Abstract
The advent of positive psychology has triggered research into positive interventions, which focus on strengths instead of deficits. The present study aims to investigate the effects of gratitude and strengths-based interventions on happiness and depressive symptoms against a control group, as well as to explore personality traits as moderator variables of the potential effectiveness of these interventions. A total of 122 participants completed at least two stages of the research. Data were collected at three stages—baseline pre-test, post-intervention assessment, and 1-month follow-up assessment. The findings partially support the effectiveness of the gratitude and strengths-based interventions in increasing happiness and decreasing depressive symptoms compared to a control group. Two personality domains showed significance as moderator variables. More research is needed to enable a higher degree of control when administering these promising interventions.
