Promoting positive outcomes through strengths interventions: A literature review

This paper reviews studies of strengths interventions published between 2011 and 2016. Strengths interventions aim to promote well-being or other positive outcomes by facilitating strengths identification, and sometimes also strengths use and/or development. The present review provides an overview of the different strengths interventions that are investigated, their effectiveness, and moderating and mediating factors. Results of the 18 (quasi-)experimental studies that were identified through a systematic literature search showed that all types of strengths interventions had positive outcomes in terms of well-being, job outcomes (e.g. work engagement), personal growth initiative, and group or team outcomes (e.g. class cohesion). Hope, positive affect, authentic self-expression, perceptions of the employment relationship, and feelings of social worth were identified as mediators, whereas extraversion and having specific strengths (e.g. persistence) were identified as moderators. Based on these findings, we discuss implications for future research and practice.
