ABSTRACT Higher levels of reliance on cognitive reappraisal to manage daily emotional events are commonly associated with lower levels of depressive symptoms. However, reappraisal is a cognitively demanding regulation strategy, and its efficacy may depend on how successfully an individual is able to employ it. Individual differences in the association between reappraisal use and depressive symptoms may be particularly evident during adolescence, when the cognitive skills required to implement this complex strategy are still in development. The current study sought to determine whether the association between reappraisal use and subsequent depressive symptom development is contingent on perceived regulatory success when using reappraisal. At Wave 1, adolescents (n =  178, mean age = 13.92, 49.7% female) used an experience-sampling smartphone app to report on their reappraisal use and perceptions of regulatory success over the course of two weeks. Six, 12, and 18 months later, adolescents completed a self-report measure of their depressive symptoms. Results showed that a) reappraisal use was associated with both subsequent depressive symptoms and trajectories of depressive symptoms over time, b) these associations were moderated by perceptions of regulatory success. Higher levels of reappraisal use were associated with lower levels of depressive symptoms only for those who reported higher than average between-subject regulatory success when reappraisal was enacted.
