This review systematically synthesised information of strengthen-based intervention programmes for adults conducted in Latin America, and summarized the current body of evidence available about the methodological quality, efficacy and/or effectiveness of these programmes, as well as implications of the findings for future research and evidence-based practices in Psychology. Medline, Scopus and PsycINFO databases (no chronological window restriction) were searched for empirical work on strengthen-based interventions programme. Overall, 15 studies were included and assessed for methodological quality. The interventions selected focused on assertiveness, empathy, coping, forgiveness, gratitude, optimism and resilience. The results revealed that 100% of the studies identified some kind of positive effect after intervention. However, methodological quality of studies showed a variety of pitfalls. Only 46% of studies achieved high quality and two studies applied experimental design (randomization). Implications for future research on intervention outcome assessment are discussed.
Keywords: positive psychology, methodological quality, intervention programme.
