ONLINE FLOW AND E-SATISFACTION IN HIGH INVOLVEMENT PURCHASING PROCESSES

This research aims to verify the relation between the attributes of online shopping experiences, the state of online flow, and e-satisfaction in high-involvement purchases. To reach that goal, we conducted a survey with 720 e-consumers. We adopted quotas sampling, using age distribution as criteria. To analyze the data, we used Structural Equation Modeling. From the statistical analysis, we found that there are some attributes of online shopping experiences that directly influence e-satisfaction (convenience associated with the website, exchange and return policies, and quality of delivery service), while others influence the state of flow online (perceived innovation on the website, price and aesthetics of the website), which, in turn, influences e-satisfaction. Additionally, we identified two attributes that influence both flow online and e-satisfaction: reliability attributed to the website and variety of products available for sale on the website.


INTRODUCTION
Internet access became easier because of improvements in the infrastructure of telecommunications (Wachter et al., 2000).Consequently, the e-business moved forward and became more evident.
Electronic business, also known as e-business, can be defined through the use of communication technologies, among which stand out those related to the Internet, to interconnect and support business processes, and to communicate and collaborate within an organization and between it and its customers, suppliers, and other partners (Laudon and Laudon, 2010;O'Brien, 2004).
Among the different electronic business arrangements described by Gonçalves and Ferreira (2010), e-commerce is noteworthy due to the significant growth achieved by this business format in recent years.The growing competition in e-commerce is inducing more and more companies to seek the satisfaction of consumers, which, in turn, reflects the continuity of the relationship, in loyalty, favorable attitudes and positive word-of-mouth advertising (Rossi and Slongo, 1998).
The satisfaction of e-consumers or e-satisfaction results, according to Dholakia and Zhao (2010) e Bansal et al. (2004), from several factors, many of them associated with attributes of online shopping experience, which are evaluated before, during and after the finalization of the electronic purchase transaction.Those same authors argue there is no concordance between researchers about which of these attributes are more relevant to formation of e-satisfaction.
However, besides the attributes of shopping experience, there are personal and psychological aspects influencing the e-consumers behavior, including online flow, which is a state of deep immersion reached by an individual during online purchase process (Hoffman and Novak, 1996).Studies show that flow state in e-commerce increases attention, improves attitudes and increases purchase intent in a particular website (Hoffman and Novak, 2009;Van Noort et al., 2011).Nevertheless, there are no studies linking the online flow to e-satisfaction yet.
Starting from the lack of agreement among researchers about which attributes of online shopping experience influence e-satisfaction, as well as the absence of studies linking online flow of e-satisfaction, was defined as general goal for this research verify the relation between the attributes of online shopping experiences, the state of online flow and e-satisfaction in high-involvement purchases.
The importance of this work lies in three key points: (i) the relevant expansion of e-commerce in Brazil, coupled with the trend of future growth; (ii) the issue of importance of customer satisfaction in the context of e-commerce; and (iii) the lack of scientific studies that discuss this topic associated with consumer involvement and online flow.

CONSUMER INVOLVEMENT IN THE PURCHASE DECISION PROCESS
According to Hanna et al. (2009), Blackwell et al. (2005), Mowen and Minor (2003), Sheth et al. (2001), Schiffman and Kanuk (2000), and Wells and Prensky (1996), the efforts made by consumers in the purchase process vary depending on his involvement with specific products or services.In lowinvolvement situations, consumer attaches little importance to the procurement process and does not believe that increasing effort to acquire the product or service significantly increases benefits.On the other hand, in situations involving highinvolvement, the consumer attribute high importance to the buying process and expects significant benefits if greater effort is made to acquire products or services.
According to Mitchell (1979), involvement is a concept that expresses an emotional state awakened in the consumer for a particular product or service.Complementarily, Zaichkowsky (1985) and Petty and Cacioppo (1981) define involvement as a measure of congruence between the meanings attributed to specific products or services and the values of consumers, while Higie and Feick (1989) and Bloch et al. (1986) argue that the concept of involvement refers to the interest shown by consumers by specific products or services.Mittal (1989) argues that there are two types of consumer involvement: involvement with a specific product or service, that reflects the degree of interest that individuals associate with a specific category of goods or services, and involvement with the purchase process, that reflects the level of interest and consumer concern about the acquisition of a product or service and include the care of the consumer in the search for information and evaluation of alternatives; the strong focus on making the right decision; and the concern about the possible outcomes of the choice.This author explains that the involvement with the product and the involvement with the purchase process are not identical constructs because consumers who typically do not show great interest in a specific product category may have high involvement in the process of buying a product belonging to this category.
Consumer purchasing behavior is not always the same, i.e., is not constant in all situations, and is modified according to the degree of involvement shown by individuals.At one extreme, involving low-involvement situations, the consumer tends to present a simplified behavior of purchase and reduces the efforts directed to the process of acquiring goods and services (Hanna et al., 2009;Solomon, 2008;Hawkins et al., 2007;Blackwell et al., 2005).At the other extreme, involving situations of high-involvement, the consumer tends to have a more complex buying behavior and increases the effort expended in the purchase of products and services (Hanna et al., 2009;Solomon, 2008;Hawkins et al., 2007).

ONLINE FLOW AND E-SATISFACTION IN HIGH INVOLVEMENT PURCHASING PROCESSES
According to Solomon (2008), purchase behavior resulting from high consumer involvement is most common in situations characterized by a high cost of the product to be purchased and non repetition of purchase.

ONLINE FLOW
In 1975, Csikszentmihalyi proposed the Flow Theory, which intended to explain the cognitive-emotional status achieved by individuals in different activities such as various sports and dance (Congwen et al., 2010).
According to the Flow Theory, when individuals are fully engaged in the implementation of any particular task or activity, they can experience a sense of flow, when they are completely immersed and deeply absorbed in the accomplishment of the task (Congwen et al., 2010).When individuals are in such a state of flow, they fail to pay attention to the time that is passing while performing the task and ignore other activities (Congwen et al., 2010).Hoffman and Novak (1996), starting from the flow theory, analyzed the state of flow experienced by consumers during their purchases in e-commerce, and confirmed that individuals can reach a state of deep immersion in these activities too.For them, the concept of flow is related to total user engagement and subsequent immersion in performing a certain activity, such as shopping online.
Also according to Hoffman and Novak (1996), the state of flow reached in online activities can be characterized by a sense of natural fun experienced by consumers.It is accompanied by the loss of self-consciousness and lack of reflection during the navigation into the website in which those are browsing.After Hoffman and Novak's work (1996), several other authors focused their studies on understanding the flow state experienced by consumers in e-commerce, among which are Chen et al. (1999), Novak et al. (2000Novak et al. ( , 2003)), Huang (2003Huang ( , 2006)), Choi et al. (2007), Hoffman and Novak (2009) and Van Noort et al. (2011).
In her study, Huang (2006) argued that the flow state can be characterized by complete immersion of consumer in the online buying activity.This occurs when the consumer's attention is focused exclusively on the interaction with the website and his curiosity is stimulated.
According to Hoffman and Novak (1996), Novak et al. (2000), Huang (2003), Choi et al. (2007), Hoffman andNovak (2009), andVan Noort et al. (2011) there is relationship between website's interactivity and state of flow, the first term being antecedent of the second.Additionally, Congwen et al. (2010) and Agarwal and Karahanna (2000) showed that enjoyment experienced by consumers when they are navigating in a particular retail site affects the flow state, while Congwen et al. (2010), andHuang (2003), reported that perception of innovation that individuals associate with a particular website increased the flow of consumers when they interact online.Finally, Bridges and Florsheim (2008), Hoffman andNovak (1996), andNovak et al. (2000), pointed that online telepresence increases the perception of reality of website, and consequently increases the state of flow during the online shopping experience.
According to above-mentioned authors, there are some attributes of online shopping experience, related with the website where purchases are made, that lead e-consumers to experience online flow.Based on that, it was defined the following hypothesis: H 1 : In high involvement purchases, attributes of online shopping experience influence the state of online flow of Brazilian e-consumers.
After presenting the elements that precede the flow state experienced in online activities, next, we discuss how this cognitive state of immersion and total concentration influences buying behavior.According to Van Noort et al. (2011), the state of flow influences consumers in three different dimensions: cognitive, affective, and behavioral.
In the cognitive dimension, the state of flow extends the consumers' attention to informational elements of the website, including the information available about products sold and the virtual retailer itself, as well as the absorption capacity, and processing of information (Van Noort et al., 2011;Hoffman and Novak, 2009;Choi et al., 2007).
In the affective dimension, the state of flow influences the attitudes developed by consumers regarding the website and the online retailer's brand.In this sense, when individuals reach a significant state of immersion when browsing into a website, they tend to develop more favorable attitudes toward electronic sales environment that they are exploring (Van Noort et al., 2011;Choi et al., 2007;Richard and Chandra, 2005;Korzaan, 2003).
Finally, in the behavioral dimension, the state of flow impacts consumers' intentions to purchase.They intend to visit the website with intention to make present and future purchases and adopt exploratory behavior while on the website (Van Noort et al., 2011;Hoffman andNovak, 2009, 1996;Huang, 2006;Richard and Chandra, 2005;Wu and Chang, 2005).
Analyzing the impacts or effects that online flow has on e-consumers in three different dimensions (cognitive, affective and behavioral), associated with the lack of studies that linking online flow and e-satisfaction and, consequently, the need to investigate this relation, was proposed the following hypothesis: H 2 : In high involvement purchases, the state of online flow influences e-satisfaction of Brazilian e-consumers.

ATTRIBUTES OF ONLINE SHOPPING EXPERIENCE THAT INFLUENCE E-SATISFACTION
After conducting an extensive literature review, it was possible to identify different attributes mentioned by several authors as being important for consumer satisfaction in e-commerce, which can be divided into three categories.These categories are related to the stages in which there is evaluation by consumers: attributes evaluated during placing the purchase order, attributes evaluated after the request has been completed and before the goods have been delivered, and, finally, attributes evaluated after the products were delivered.
The attributes evaluated by the consumer during the order placement are the most numerous and include: (1) customer service, (2) customization, (3) convenience, (4) reliability, (5) aesthetic and organization of the virtual store environment, (6) reputation of the retailer, (7) information available, (8) prices, (9) website response time, and (10) variety in the retail assortment.The attributes evaluated by the consumer in the time interval between the end of the order and delivery, are: (1) the payment process, and (2) the possibility to follow the order and track the delivery.Finally, the attributes evaluated by the consumer after the products have been delivered are: (1) delivery service, (2) return and exchange policies of the company, and (3) the quality of products.
Regarding the "service" attribute, consumers expect the retailer to have a synchronous online service channel so questions can be answered quickly (Zhao and Dholakia, 2009;Holloway and Beatty, 2008).Consumers also expect that attendants present a polished and gentle posture (Fasanghari and Roudsari, 2008;Posselt and Gerstner, 2005); that the response time is efficient (Fasanghari and Roudsari, 2008); and that attendants show great knowledge about the products sold by the company, the company's business policies and the purchase transactions on the website (Fasanghari and Roudsari, 2008;Posselt and Gerstner, 2005).
Relative to attribute "customization", individuals are more satisfied when personalized offers are developed that meet their consumer habits and preferences (Lin and Sun, 2009;Lee and Kozar, 2006;Schaupp and Belanger 2005;Madu and Madu, 2002).
Another important attribute for the formation of esatisfaction is the convenience that consumers perceive when conducting transactions in virtual environments (Eid, 2011;Lin and Sun, 2009;Evanschitzky et al., 2004;Szymanski and Hise, 2000).The convenience includes, in retailing, all the elements that facilitate user navigation, the search for information and products, and the online transaction (Zhao and Dholakia, 2009;Kim et al., 2009;Chung and Shin, 2008;Kim et al., 2007).
In addition to the attributes shown above, another important attribute in the formation of online satisfaction is the reliability assigned to a particular retailer, which includes the consumer's perception about the privacy and security of the virtual store, as well as how much the retailer's behavior is ethical (Kassim and Abdullah, 2010;Liu et al., 2008;Martín and Camarero, 2008;Cheung and Lee, 2005).
Relative to attribute "website design", consumers value that visual elements of the website are attractive and organized to facilitate navigation; with this, the e-satisfaction tends to be higher (Wang et al., 2011(Wang et al., , 2010;;Kim et al., 2009;Cyr, 2008;Liu et al., 2008;Martín and Camarero, 2008;Lee and Lin, 2005;Shankar et al., 2003;Szymanski and Hise, 2000).It should be noted that, according to Chen et al. (2008), there is a theoretical gap in studies on e-satisfaction, consequence of the lack of discussion about innovation of website design.
In addition, another important attribute for the formation of e-satisfaction is the website's brand.Lee and Kozar (2006) argue that the brand reputation of a retailer is a factor of attraction, retention, and customer satisfaction.Brands arouse greater consumer confidence, reduce the perception of risk associated with e-commerce, and increase online satisfaction (Rose et al., 2011).
Besides the attributes cited earlier, another attribute that influences e-satisfaction is the quality of information made available by the electronic retailer, which is evaluated based on criteria such as accuracy, relevance, and clarity (Eid, 2011;Cyr, 2008;Chung and Shin, 2008;Jun and Chung, 2006;Lee and Kozar, 2006;Cheung and Lee, 2005;Madu and Madu, 2002).
Customer satisfaction in e-commerce is also influenced by the prices charged by retailers.When individuals perceive that are saving money and paying fair prices, they feel more contentment after finishing the purchase (Martin and Camarero, 2008;Lee and Kozar, 2006;Shun and Yunjie, 2006).
Another attribute that influences e-satisfaction is response time of website, which refers to aspects such as the loading time of the information requested by individuals and speed of navigation (Chung and Shin, 2008;Cheung and Lee, 2005;Evanschitzky et al., 2004;Madu and Madu, 2002).
According to Dholakia and Zhao (2010), Fasanghari and Roudsari (2008), Holloway and Beatty (2008), Liu et al. (2008), Evanschitzky et al. (2004) and Szymanski and Hise (2000), esatisfaction is also influenced by the individual's perception about the variety of products available, because consumers tend to be more satisfied when they realize they have choices.In addition, besides the range of products available, consumers also evaluate the quality of the products purchased.After receiving the products, consumers evaluate whether the specifications of the delivered products meet specifications informed by the retailer on their website (Holloway and Beatty, 2008;Shun and Yunjie, 2006).
Another important attribute for the formation of esatisfaction is the payment process.More forms and payment options available by the virtual store contribute to a greater perception of control by the consumer; consequently, the greater the satisfaction level (Liu et al., 2008).Moreover, the complexity involved in the payment process also influences the online satisfaction: consumers feel less uncomfortable when the process is simpler and faster (Zhao and Dholakia, 2009;Holloway and Beatty, 2008).
Besides the payment process, the possibility for consumers to follow the progress of their order and track the delivery also influences e-satisfaction (Dholakia and Zhao, 2010;Kim et al., 2009;Holloway and Beatty, 2008;Schaupp and Belanger, 2005).
Fasanghari and Roudsari (2008) argue that consumers also attach great importance to the services provided by organizations working in e-commerce, such as the delivery of products.The assessment that consumers make about a retailer delivery service involves different aspects such as compliance with the informed term (Fasanghari and Roudsari, 2008;Collier and Bienstock, 2006;Schaupp and Belanger, 2005;Wang and Huarng, 2002), delivery of correct products (Holloway and Beatty, 2008;Collier and Bienstock, 2006), appropriate product packaging and conditions of delivered products (Dholakia and Zhao, 2010;Liu et al., 2008;Posselt and Gerstner, 2005).
Finally, exchange and return policies of goods are another attribute that influences the e-satisfaction because they reduce the discomfort and consumer distrust (Wang and Huarng, 2002).Holloway and Beatty (2008), Martín and Camarero (2008), and Cheung and Lee (2005) argue that these policies influence the confidence that consumers deposit in transactions made online as well as satisfaction, because ensure return of products that do not meet expectations or exchange, if a problem occurs with the product.
Analyzing the authors consulted, it was possible to conclude that different attributes of online shopping experiences influence e-satisfaction.In this sense, the following hypothesis was defined: H 3 : In high involvement purchases, attributes of online shopping experience influence e-satisfaction of Brazilian econsumers.

METHODOLOGICAL ASPECTS
To achieve the research goal, we collected quantitative primary data by conducting a field survey.A structured questionnaire was used, composed with questions in a structured scale format.The elaboration of the questionnaire was based on the research hypotheses.
At the beginning of questionnaire, was included a solicitation to respondents answer the questions thinking in a purchase of high involvement and a brief explanation of what was considered a high-involvement purchase.It was adopted the perspective of Solomon (2008), that high involvement of consumer is most common in situations characterized by a high cost of the product to be purchased and non repetition of purchase.
The questionnaire was divided in three parts.First, theoretical constructs identified in the literature review as antecedents of e-satisfaction (attributes that are part of the online shopping experience and influence e-satisfaction) gave rise to a set of one to four questions or statements which were included in the questionnaire, which can be explained by the fact that they are multidimensional and include more than one aspect.Second, the construct "online flow" gave rise to three statements, which also can be explained from its multidimensionality.Finally, the construct "e-satisfaction" gave rise to five statements, considering five complementary theoretical perspectives were identified that can be used to measure it (Ceribeli, 2015).
The scale used to structure the questionnaire was Likert seven-point, whose extremities were "totally disagree" and "totally agree".We chose a scale of seven points, considering that respondents tend to avoid extremes, i.e., five-point scales can become, in practice, three-point scales (Hair Junior et al., 2005).
Before proceeding to data collection, it was conducted a pretest with 10 individuals in order to identify and correct ambiguities and other problems in the drafting of the questions.Based on the results obtained, two questions were rephrased.After that, a new pretest was conducted and no additional problems were pointed.
The questionnaire was circulated on social networks by researchers.To increase the response rate, some individuals were selected to disseminate the questionnaire at the same time as researchers (these individuals agreed to publish the link to questionnaire every two days during the period of one month.Thus, disclosure of the questionnaires was repeated 15 times in the aforementioned period, both on Facebook and Linked In. For this research, the target population was defined as all inhabitants of the states of São Paulo and Espírito Santo, between 18 and 49 years, who carry out Internet purchases.Choosing the States of São Paulo and Espírito Santo reflects the researcher's ease of access to sample units.We opted for non-probabilistic sampling by quotas, which considers the existence of subgroups in the target population and is based on distribution of these subgroups (Hair Junior et al., 2005).To implement the sampling quotas in this study, the target population was stratified using as criteria the age group of consumers.
The percentage of each group of e-consumers in the research sample was defined from data of E-Commerce (2013) transformed to the base 100.To ensure that the population strata were represented in compliance with the defined percentage, when the pre-stipulated amount of answers to specific stratum was reached new responses for the same stratum were excluded.
To set the sample size, we followed the recommendations of Hair Junior et al. (2009), who suggested that when we adopted multivariate statistical techniques to analyze the data collected, the sample size should be 10 to 20 times the number of variables included in the survey.
The questionnaire includes 42 questions (research variables), so research sample consisted of 720 respondents, of which 10 were excluded due to errors in filling out the questionnaire.Thus, 710 responses were validated, which represents approximately 98.6% of the responses collected.
In data analysis, we used Structural Equation Modeling (SEM), merging the approaches Pathway Analysis and Confirma-tory Factor Analysis.The choice for SEM is justified based on the existence of more than one dependent variable (online flow and e-satisfaction).The results obtained from the SEM were analyzed as follows: first, we examined for the existence of transgressive estimates (negative variances of error, surplus standardized coefficients or very close to 1.0, or standard errors very large); then we analyzed the overall fit of the model obtained using absolute fit measures, incremental and parsimonious; finally, we interpreted the coefficients obtained based on the theory previously consulted to validate or refute the research hypothesis.

RESULTS PRESENTATION AND DISCUSSION
In order to facilitate analyses, each variable received a label, as shown in Chart 1.
After carrying out a Skewness and Kurtosis analysis, it was found that only the variable CUSTOM stands out by presenting an asymmetrical behavior and a kurtosis higher than the recommended value, which may indicate the absence of normality.To confirm the existence of normality or not, we made the LM test proposed by Jarque and Bera (1987).From the results of LM tests for each variable, it was possible to confirm the analysis of skewness and kurtosis made earlier, i.e., only the variable CUSTOM did not follow a normal distribution; the other variables met the assumption of normality.Therefore, we opted to exclude the CUSTOM variable.
After the analysis of the data normality, the assumptions of homoscedasticity, linearity, and absence of autocorrelation, were tested.First, we used graphic analysis of the standardized residuals versus the predicted dependent values, as recommended by Hair Junior et al. (2009) and Gujarati (2006).To complement the graphical analysis, we used the test d of Durbin-Watson and Pesaran-Pesaran test.After testing basic assumptions for multivariate analysis, we decided to delete three of the 42 original variables of the study due to lack of linearity (SERV1, TRUST2 and VARIE2).
For statistical analysis of data, we used Structural Equation Modeling (SEM) combining Pathways Analysis and Confirmatory Factor Analysis.Confirmatory Factor Analysis was used to group the observed variables of the survey, resulting in a smaller number of latent variables.In turn, Pathways Analysis was used to analyze the relationship between the variables that measured online shopping experience and the latent variables "online flow" and "e-satisfaction" as well as the relationship between these two variables.
Whereas the Confirmatory Factor Analysis creates latent variables from the original variables, it was necessary to verify, prior to analysis, whether it would be appropriate to aggregate the original variables or not.For this, we used Bartlett's test of sphericity, associated with the KMO (Kaiser Meyer Olkin) and Cronbach's Alpha.
Simultaneously analyzing the KMO coefficients, the calculated values of Cronbach's Alpha, and the p-values of Bartlett's test of sphericity, we identified only three sets of variables that could effectively be grouped by Confirmatory Factor Analysis, resulting in three latent variables (INNOV1 and INNOVA2; FLOW1, FLOW2 and FLOW3; SATIS1, SATIS2, SATIS3, SATIS4 and SATIS5).The remaining variables (all of them representing different attributes of online shopping experience) were placed on Structural Equation Modeling individually.
After defining which variables were grouped by Confirmatory Factor Analysis, we structured through AMOS software, a first structural equation model, which included three latent variables (INNOV, FLOW and SATIS), being two endogenous (FLOW and SATIS) and one exogenous (INNOV), and twentyeight observed exogenous variables.It should be mentioned that the decision to include observed variables related with attributes of online shopping experience instead of a unique latent variable to represent this construct is justified by the possibility of identify specifically which attributes influence the state of flow and which influence e-satisfaction.
For our estimation procedure, we opted initially to use the method of Generalized Least Squares, commonly used in Structural Equation Modeling.However, when a Mardia coefficient was obtained that went beyond the acceptable upper limit of 1.96, indicating possible absence of multivariate normality, we opted for the Asymptotically Distribution-Free method, due to the fact that this does not seem sensitive to absence of multivariate normality of data (Hair Junior et al., 2009).This first model had generated problem identification, i.e., the AMOS software identified that the structured model had no ability to generate single estimates.
To solve the identification problem encountered, we developed a simpler model (with only three variables: IN-NOV, FLOW and SATIS), which was used as a starting point to perform various tests and gradually include the twentyeight observed exogenous variables.At the end of testing process, we maintained the three latent variables (being two endogenous and one exogenous) and only fourteen observed exogenous variables.
The quality of fit obtained was examined through three measurements.The root mean square error of aproximation or RMSEA was 0.056, lower the than borderline recommended of 0.08 (Garson, 2012;Arbuckle, 2010;Hair Junior et al., 2009).The adjusted goodness-of-fit index or AGFI was 0.813, close to 1.0, that is the value that points perfect adjusts (Garson, 2012;Arbuckle, 2010;Hair Junior et al., 2009).Finally, the normed Chi-square was 3.247, lower than the borderline recommended of 5 (Schumacker and Lomax, 2004;Joreskog, 1970).
After validating the quality of the fit of the proposed model, we validated latent variables included in the structural equation model.After validating the latent variables created, we analyze the regression coefficients of the relationship between latent endogenous variables FLOW and SATIS and the exogenous variables.These coefficients are presented in Table 1.The structural equation model was able to explain

From the performed hypotheses tests and beta coefficients analyzed, we found that the variables which positively influence the state of online flow of consumers in high involvement purchases are: (1) the innovation of website, (2) the reliability assigned to the electronic retailer, (3) the variety of the assortment available on the website, (4) the aesthetics of the virtual environment, and (5) the prices charged by the company.
Furthermore, we found that the variables which positively influence online consumer satisfaction in high involvement purchases are: (1) online flow state, (2) the convenience associated with the website navigation, (3) the variety of assortment available on the website, (4) the reliability attributed to the electronic retailer, (5) the fulfillment of delivery deadlines, and (6) the existence of exchange and return policies perceived as fair.
Based on these results, a model was proposed to explain online flow and e-satisfaction in high-involvement purchases, shown in Figure 1.
First analyses of the state of online flow in high involvement contexts highlights the importance of consumer percep-

Endogenous Variable
Exogenous tion that the website design is innovative and differentiated in relation to others, corroborating the results of studies conducted by Congwen et al. (2010) and Huang (2003).
The relationship between the website innovation and online flow can be explained by one dimension of online flow proposed by Huang (2006) and Congwen et al. (2010): the consumer curiosity during navigation.If website is different and innovative, naturally curious and engaged the consumer will be.Besides, if innovation it's seen in the website, the consumer will explore it with more concentration.Both behaviors are pointed out by Van Noort et al. (2011) as a characteristic behavior of consumers who have hit the state of online flow.
Regarding the influence that the level of reliability assigned to the website has on the state of flow, we identify that when a individual feels that a certain electronic retailer is reliable and believes he would not act in bad faith with his customers, there is a higher possibility of this individual entering into a state of flow, i.e., favorable attitudes of consumers towards a particular electronic retailer increases the chances of they experience greater immersion when browsing that website.
This finding can be understood in a more coherent way when considering that one of the obstacles to achieving a state of online flow can be the insecurity experienced by consumers while they browse on a website.Following this line of thought, when consumers feel that the company is reliable, they maintain a less defensive posture regarding the website and have the possibility of experiencing more fun and deep engagement during navigation.
Continuing with the discussion of the features of online shopping experiences that precede the online state of flow, with respect to the influence that variety of products available at website has on online flow, we identify that consumers may feel more curious when viewing a website with greater options.Furthermore, the availability of a wide assortment by the electronic retailer can maintain consumers interested and without consciousness of time while evaluating the alternatives that are available, going into a state of flow.
In addition, when exploring the relationship between online flow and website aesthetics, it appears that consumers can feel more encouraged to navigate when they are required to use less effort to understand the structure of the website.In this sense, websites that present a logical organization of its products (e.g., section of male, female, and children's items), making navigation of consumers easier, can awaken greater interest, contributing to consumer immersion during the online purchase process.
Finally, exploring the relationship between online flow and prices, we hypothesized that the perception of consumers that a website has lower prices than those charged by other physical or electronic retailers exerts a "relaxing" effect, reduces anxiety during navigation and increases interest in the website.Thus, the perception that prices are lower can increase the immersion of consumers while browsing, because they feel that don't need to pay attention to monetary matters and, consequently, start to perceive other website elements (such as range of products, information available, website aesthetics, etc.), experiencing a more complete online shopping experience, which leads them to attain online flow.
Having addressed the elements associated with online shopping experiences that exert relevant influence on the online flow state, we next discuss the elements that influence the e-satisfaction in high involvement purchases.
Starting the discussion with the relationship between esatisfaction and online flow, it appears, based on the proposed structural equation model, the individual immersion, loss of self-consciousness, high curiosity, and natural fun experienced during navigation into a website tend to positively influence e-satisfaction in high involvement purchases.Thus, consumers coming into a flow state have a higher chance of being satisfied with the shopping experience in virtual shopping environments, which highlights the influence that cognitive-emotional states experienced during the navigation has on e-satisfaction.In a complementary way, with regard to the relationship between convenience and e-satisfaction in high involvement contexts, it is noteworthy that, as advocated by Eid (2011), Lin and Sun (2009), Evanschitzky et al. (2004), Burke (2002) and Szymanski and Hise (2000), ease perceived by consumers in conducting transactions in virtual environments tends to positively influence satisfaction.
Items that increase the ease perceived by consumers buying at e-commerce identified in the literature review include tools of price/product comparison (Schaupp and Belanger, 2005), website maps, FAQ, instructions available, easy registration (Kim et al., 2009), and search tools (Kim et al., 2009;Zhao and Dholakia, 2009;Chung and Shin, 2008;Lee and Lin, 2005).All these elements tend to reduce the effort required for consumers navigate the website and complete their purchases in less time.
Analyzing the dimensions of convenience, Berry et al. (2002) reiterate that e-commerce stands out for convenience of decision and transaction because it reduces the time and effort involved in finding information regarding specific products and services, comparison of competitors, and evaluation of shopping alternatives.
Analyzing the relationship between website's assortment and e-satisfaction, it appears that a large assortment significantly influences the satisfaction experienced by consumers in online purchasing processes of high involvement.This finding is consistent with studies of Dholakia and Zhao (2010), Holloway and Beatty (2008), Evanschitzky et al. (2004), Burke (2002), and Szymanski and Hise (2000), which relate the number of options available to consumers and online satisfaction.Furthermore, as explored by Liu et al. (2008) and Fasanghari and Roudsari (2008), individuals feel more satisfied when they realize they have ample choice.
This finding is also in agreement with the results obtained by Martín and Camarero (2008) and Posselt and Gerstner (2005), who concluded that consumers, after finalizing the online purchase, feel more satisfied when they see different purchase options, many of which are not available in traditional retail, optimizing their process of choice.
In turn, the relationship between e-satisfaction and reliability is supported by the studies of Rose et al. (2011), who found that websites that are associated with greater confidence tend to reduce the perception of risk associated with e-commerce and elicit favorable attitudes from consumers, increasing satisfaction.Therefore, as greater the confidence in the retail brand, lower is the cognitive dissonance or discomfort of the individual after placing the purchase order, which tends to positively influence the online satisfaction (Rose et al., 2011;Fasanghari and Roudsari, 2008;Schaupp and Belanger, 2005).
The credibility of electronic retailers is directly related to consumer perception about the privacy and security of the website, as well as the guarantees offered (Kassim and Abdullah, 2010;Cheung and Lee, 2005;Ribbink et al., 2004;Wang et al., 2003).When there are adequate security and privacy policies, the consumer discomfort tends to be lower after placement of purchase orders, which increases the sense of control and e-satisfaction (Martín and Camarero, 2008).
The relationship between the quality of delivery service and e-satisfaction was also identified, which is in line with the studies of Parasuraman et al. (2005) and Collier and Bienstock (2006), who argue that e-consumers overestimate the quality of delivery service in electronic environments, because they are affected in a very negative way by failures in this regard.According to Dholakia andZhao (2010), Fasanghari andRoudsari (2008), Holloway and Beatty (2008), Liu et al. (2008), Posselt and Gerstner (2005), Schaupp and Belanger (2005), and Wang and Huarng (2002), the delivery time is essential in the evaluation of consumers.If the time between order placement and delivery of the product does not correspond to the deadline previously informed by the retailer, the consumer tends to become very dissatisfied (Fasanghari and Roudsari, 2008;Schaupp and Belanger, 2005).
Looking at the issue of delivery time from the perspective of cognitive dissonance, we consider that, when the deadline previously informed by the e-retailer is not respected, the consumers' post-purchase discomfort tends to increase, which can be explained by geographical distance between buyer and seller and the intangibility of the online purchase process.When this occurs, the post-purchase satisfaction levels tend to suffer large losses.
Finally, we cite the importance attributed to the exchange and return policies.The structural equation modeling shows that the perception of fair exchange and return policies tends to positively influence the e-satisfaction, corroborating studies Holloway and Beatty (2008) and Wang and Huarng (2002).
Exchange and return policies of an e-retailer can transmit greater security to an e-consumer that there will be no major obstacles for the return of products that do not meet expectations, and/or easy exchange of the purchased product if a problem occurs.Therefore, as exchange and return policies reduce risks and discomfort associated by individuals to e-commerce, tend to increase e-satisfaction (Martín and Camarero, 2008;Cheung and Lee, 2005).
To conclude, we made a comparison between the elements of online shopping experiences that influence e-satisfaction and those that influence the state of flow.Our results show that only two elements influence both: the variety of products available on the website and website credibility.In this regard, it is noted that, in addition to increasing interest and immersion of consumer when browsing a certain website, the availability of several product also guarantees that the online shopping experience become more satisfying.In addition, it appears the credibility of the electronic retailer reduces psychological resistance associated with the online buying process and the website, which may leaves a consumer to experience the state of flow and also increases his e-satisfaction.
Factors that were not significant for the e-satisfaction or the online flow include the information available on the website, the degree of customization of offers, and the response time of the website, which may be the subject of future studies, considering that, although they do not affect the esatisfaction, they could influence consumer choice between different websites.

FINAL CONSIDERATIONS
Contextualized by the significant growth that Brazilian e-commerce has shown in the last decade, this study aimed to analyze the relation between the attributes of online shopping experiences, the state of online flow and e-satisfaction in high-involvement purchases.To achieve this goal, we made a literature review in order to identify all theoretical elements of online shopping experience that could influence e-satisfaction.
From the statistical analysis of data on high involvement purchases, we found there are some attributes of online shopping experiences that directly influence e-satisfaction (convenience associated with the website, exchanges and return policies, and quality of delivery service), while others influence online flow state (perceived innovation on the website, prices, and website aesthetics), which, in turn, influence the e-satisfaction.Additionally, we identified two attributes that influence both online flow and e-satisfaction (reliability attributed to the website and variety of products available for sale on the website).
Analyzing the relationships identified, it appears that more involved consumers tend to entry into a deep state of immersion while shopping when faced with more innovative and organized virtual environments, and when they realize that the prices of website are attractive.
In addition, more involved consumers tend to be more satisfied when the delivery of purchased products is realized within the time specified by the electronic retailer at time of purchase, when they perceive that exchanges and returns policies of the company are fair, and when they can explore the website without major difficulties.
Thus, we can accept the three research hypotheses, i.e., some attributes of online shopping experience influence online flow and/or e-satisfaction of Brazilian e-consumers, and the state of online flow influences e-satisfaction of these same consumers.This findings show there is relationship between online shopping experience, online flow and e-satisfaction in high involvement purchases.
As implications of this research, we have that e-companies should prioritize three aspects of its business: structure and design of online store (website), service level to consumers and reputation.These, added to prices, can be pointed as critical success factors to companies seeking to compete in the virtual market adopting a strategy focused on the customer.
As a managerial contribution of this research, we identified attributes of shopping experiences of high involvement that should be monitored by virtual retailers to increase online flow and satisfaction of e-consumers.Thus, this research presents a vision that combines strategic decisions and operations management in e-commerce.
Additionally, as an academic contribution, this research adds to the study of consumer behavior in e-commerce.Moreover, considering the study explored e-satisfaction and online flow simultaneity and incorporated a perspective based on involvement of the e-consumer during purchase process, it can be considered innovative.
One limitation of this study is the fact that the sample was not selected randomly, reducing the generalizability of the results.However, it should be added that, by opting for sampling by quotas, the researcher was able to form a sample that had age distributions that represented the actual distribution of the population studied.Therefore, we consider that, despite not having been formed by a random selection process, the research sample represents, at least peripherally, the target population of the study.
For future research, it is suggested that the questionnaire developed be tested in other samples, enabling the comparison of results.Additionally, it is recommended that the reflections arising from the analysis of the results for high involvement purchases be the subject of future studies, consolidating the discussion started at this work.
It is also suggested that future studies analyze attributes of online shopping experiences that influences e-satisfaction in low involvement purchases.Besides, another issue to be addressed in future studies is the discussion of how demographic and cognitive characteristics of consumers can influence their buying behavior in e-commerce, based on the models proposed here.Finally, it is recommended that the construct "perceived innovation", which proved to be positively associated with online flow in high involvement purchases, be divided into dimensions and the influence of each dimension to online flow be examined separated.
