Specifically, the intervention instructs participants to use the strategy of savoring to amplify their positive emotions, fostering an appreciation for the present moment. Conversely, for the attenuation of negative emotions, the intervention advocates to use the strategy of reappraisal, encouraging participants to reinterpret adverse situations in a more positive or neutral way, thus reducing their emotional impact.

The study encompasses participants diagnosed with mild to moderate major depression or persistent depressive disorder and healthy controls without a current depressive disorder.\n\nParticipants will be randomly assigned to either the intervention group, receiving a valence-specific emotion regulation intervention in daily life, or a monitoring-only control group. The valence-specific intervention supports the implementation of different emotion regulation strategies based on whether a person is experiencing mainly positive or negative emotions. In contrast, participants in the control group will solely monitor their positive and negative emotions and the strategies used to regulate them.\n\nOutcome measures include emotion regulation ability, self-efficacy, and strategy use, depressive symptoms, positive and negative affect, and emotion beliefs (controllability, usefulness).\n\nA second aim of the study is to compare beliefs about positive emotions and strategies to regulate them between individuals with and without current depressive disorders. Furthermore, the investigators aim to examine why individuals might choose unfavorable emotion regulation strategies even when feeling good.
