- Brief Summary
This two-armed randomized controlled trial aims to investigate the effectiveness of an emotion regulation intervention in individuals with and without depressive disorders. The study encompasses participants diagnosed with mild to moderate major depression or persistent depressive disorder and healthy controls without a current depressive disorder.
Participants 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.
Outcome measures include emotion regulation ability, self-efficacy, and strategy use, depressive symptoms, positive and negative affect, and emotion beliefs (controllability, usefulness).
A 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. Therefore, another research question is, how emotion beliefs might explain emotion regulation strategy choice.
- Detailed Description
Background:
Affective disorders, such as depression, have been consistently associated with deficiencies not only in the regulation of negative emotions but also in the maintenance and upregulation of positive emotions. However, the mechanisms underlying emotion regulation deficits in depressive disorders remain inadequately understood. Recently, there has been a growing interest in the role of beliefs about emotions as factors contributing to emotion regulation deficits in psychopathology. In light of this, this study seeks to explore potential differences in beliefs about positive (and negative) emotions between individuals with and without current depressive disorders. Another aim of this study is to examine how these individual differences in emotion beliefs predict the selection of emotion regulation strategies in daily life, particularly in the context of positive emotions.
Given the pivotal role that deficits in emotion regulation play in the onset and persistence of depressive disorders, this study aims to investigate whether an ecological momentary intervention, addressing both positive and negative emotion regulation, can effectively improve emotion regulation processes. Recent research suggests that distinct emotion regulation strategies may be effective for positive versus negative emotion regulation. Consequently, this study aims to evaluate the effectiveness of a smartphone-based, valence-specific emotion regulation intervention in individuals with and without current depressive disorders.
Method:
This study will enlist participants aged between 18 and 65, diagnosed with mild to moderate major depression or persistent depressive disorder, as well as healthy controls without a current depressive disorder. Individuals presenting with a current severe substance use disorder, acute suicidality, an ongoing severe major depressive episode, a history of bipolar disorder, or lifetime psychotic disorders are precluded from participation in both groups. Additional exclusion criteria for participation within the control cohort encompass (a) occurrence of a major depressive episode in the preceding 12 months, (b) history of severe major depressive episodes, (c) diagnosis of recurrent depressive disorder or history of persistent depressive disorder, and (d) ongoing treatment modalities related to a depressive episode, including psychotherapy or pharmacotherapy.
Participants will undergo baseline questionnaires before completing four daily smartphone-based assessments over seven consecutive days, evaluating their emotion beliefs, emotion regulation, and emotional outcomes. Participants will be randomly assigned to either the intervention or the monitoring-only control group. Following a four-day break, participants in the intervention group will receive a valence-specific ecological momentary intervention targeting emotion regulation in daily life. During this period, participants will report their emotional experiences twice daily and will be supported in implementing either reappraisal or savoring strategies based on the valence of their current predominant emotion. Participants in the control group will be instructed to complete two daily assessments, monitoring their emotions and the strategies used to regulate them. After an additional four-day break, participants will be invited to complete post-assessment questionnaires capturing emotion regulation ability, self-efficacy and strategy use, depressive symptoms, emotion beliefs (controllability, usefulness), and another week of ecological momentary assessment (four per day), encompassing, among other variables, the use of emotion regulation strategies and the experience of positive and negative emotions.
Hypotheses:
The valence-specific intervention is hypothesized to enhance emotion regulation ability and self-efficacy, emotional outcomes (depressive symptoms, positive and negative affect), and emotion beliefs (controllability, usefulness) and to increase the application of reappraisal in negative and savoring in positive emotional contexts in daily life.
The investigators hypothesize that individuals with current depressive disorders will report more unfavorable beliefs about emotions and higher use of strategies associated with dampening positive emotions compared to controls at baseline.
Furthermore, the investigators expect that unfavorable beliefs about positive emotions at baseline (i.e., assuming that positive emotions are harmful) may predict the selection of dampening strategies in the context of positive emotions.

Group Intervention Description Intervention group Valence-Specific Ecological Momentary Intervention Participants complete a valence-specific ecological momentary intervention twice daily over 14 consecutive days. The ecological momentary intervention is presented as the "Positive Everyday Affect Knowledge" (PEAK) diary and includes valence-specific emotion regulation strategy instructions. Participants receive reminders to complete surveys on their strongest emotions since the last assessment. Depending on the valence of this emotion, they receive instructions on how to use the strategy savoring (for positive emotions) or reappraisal (for negative emotions).
- Primary Outcome Measures
Name Time Method Emotion Regulation Ability (Positive, Negative Emotions) 0 weeks, 3 weeks The Perth Emotion Regulation Competency Inventory (PERCI; Preece al., 2021) consists of 32 items, rated on a 7-point scale (1 = strongly disagree, 4 = neither agree nor disagree, 7 = strongly agree) and measures people's ability to regulate their positive and negative emotions. Two different composite scores can be computed to indicate positive and negative emotion regulation ability (Min = 16, Max = 112 for each score), with higher scores indicating a higher level of difficulty regulating positive or negative emotions.
Emotion Regulation Self-Efficacy for Positive and Negative Emotions 0 weeks, 3 weeks The German version of the Regulatory Emotional Self-Efficacy-Revised (RESE-R) Scale (adapted from Caprara et al., 2008) consists of 10 items, rated on a 5-point scale (1 = not at all well to 5 = very well). The scale assesses self-efficacy in expressing positive emotions (4 items, Min = 1, Max = 5) and in managing negative emotions (despondency/distress: 3 Items, anger/irritation: 3 items, Min = 1, Max = 5), with higher scores indicating higher self-efficacy beliefs.
- Secondary Outcome Measures
Name Time Method Positive and Negative Affect 0 weeks, 3 weeks Data will be collected using an adaption of the smartphone app EmoTrack (adapted from Pruessner et al., 2023). The app measures among other factors, the intensity of specific positive and negative emotions selected from the Positive and Negative Affect Schedule - Expanded Form (PANAS-X; Watson \& Clark, 1994), using an 11-point scale (1 = not at all, 11 = very much). Scores for positive and negative emotions will be aggregated across all intensity ratings from the four daily measurements over a continuous seven-day period (Min = 1, Max = 11). Higher scores indicate that participants experience a higher level of positive (resp. negative) emotions in daily life.
Emotion Regulation Strategy Use in Positive and Negative Emotional Contexts 0 weeks, 3 weeks Data will be collected using an adaption of the smartphone app EmoTrack (adapted from Pruessner et al., 2023). The app assesses among other factors, the intensity with which participants employ various emotion regulation strategies to manage specific positive and negative emotions, using an 11-point scale (1 = not at all, 11 = very much). Scores for strategy usage will be aggregated across all intensity ratings from the four daily measurements over a continuous seven-day period (Min = 1, Max = 11). Higher scores indicate that a participant engages in a specific strategy more strongly in daily life.
Depressive Symptoms 0 weeks, 3 weeks The Beck Depression Inventory-II (Wang et al., 2013) consists of 21 items, rated on a 4-point scale (0-3) with four statements of increasing severity related to a specific depressive symptom. Higher sum scores (Min = 0, Max = 63) indicate a higher severity of depressive symptoms.
Emotion Beliefs (Controllability, Usefulness) about Positive and Negative Emotions 0 weeks, 3 weeks The Emotion Beliefs Questionnaire (EBQ, Becerra et al., 2020) consists of 16 items, rated on a 7-point scale (1 = strongly disagree, 4 = neither agree nor disagree, 7 = strongly agree). Sum scores can be computed for different subscales: General-Contollability (8 Items, Min: 8; Max: 56), Positive-Usefulness (4 Items, Min: 4, Max: 28), Negative-Usefulness (4 Items, Min: 4, Max: 28), with higher scores indicating that people believe, that emotions are uncontrollable and useless.
