<p>Experiencing and upregulating positive emotions may be beneficial for adolescents’ well-being. However, in contrast to studies on regulating negative emotions, studies on positive emotion regulation (ER) have focused mainly on savoring strategies. The purpose of our study was to examine the factor (variable-centered) and profile (person-centered) structure of a novel adolescent report measure, Positive Emotion Regulation Questionnaire (PERQ), of 10 positive ER strategies used to maintain or increase happiness and investigate convergent validity with ER and mental health indicators. We recruited a sample of 349 English-speaking 13-17-year-old adolescents (50% females; 32% non-binary/other gender) using social media. Adolescents completed an online survey assessing positive ER strategies, difficulties in ER, anxiety, depression, trauma, and resilience. Exploratory factor analyses (EFA) indicated a 10-factor solution. Pearson correlations showed that Self-Improvement, Physical Activity, and Positive Thinking were positively related to resilience, Positive Thinking was negatively related to anxiety and depression, and Physical Activity was negatively related to depression. Conversely, Sensation Seeking was negatively related to resilience, Fantasizing and Sensation Seeking were positively related to anxiety, and both Sensation Seeking and Relaxation were positively related to depression. Profile analysis revealed six profiles and ANOVA results revealed significant differences in depression among some profiles. Findings demonstrate adolescents utilize a wide range of ER strategies to maintain and upregulate positive emotions. Further, certain profiles may indicate either protective or risk factors for depressive symptoms.</p>
