title: The role of positive emotion and contributions of positive psychology in depression treatment: systematic review.
abstract: The present study aims to conduct a systematic review of the literature by checking the impact of positive emotion in the treatment of depression and on the use of strategies of positive psychology which involves positive emotion to treat and reduce symptoms of depression. For this purpose, we conducted searches in databases ISI Web of Knowledge, PsycINFO and PubMed and found a total of 3400 studies. After inclusion application and exclusion criteria, 28 articles remained, presented and discussed in this study. The studies have important relations between humor and positive emotion as well as a significant improvement in signs and symptoms of depression using differents strategies of positive psychology. Another relevant aspect is the preventative character of the proposed interventions by positive psychology by the fact that increase well-being and produce elements such as resilience and coping resources that reduce the recurrent relapses in the treatment of depression. The strategies of positive psychology, such as increasing positive emotions, develop personal strengths: seeking direction, meaning and engagement for the day-to-day life of the patients, appear as potentially tools for the prophylaxis and treatment of depression, helping to reduce signs and symptoms as well as for prevention of relapses.
