Between-Individual Differences in Baseline Well-Being and Emotion Regulation Strategy Use Moderate the Effect of a...

Area of Science:

• Psychology
• Behavioral Science
• Mental Health

Background:

• Self-help emotion regulation interventions offer social benefits like mental disorder prevention.
• However, their effectiveness is often limited by significant individual differences in response.
• Understanding these differences is key to optimizing intervention outcomes.

Purpose of the Study:

• To investigate if baseline emotional well-being and emotion regulation strategy use moderate the effects of a self-help cognitive-behavioral intervention.
• To identify which individuals benefit most from such interventions.

Main Methods:

• A 4-week self-help cognitive-behavioral intervention was administered to nonclinical adults.
• Experience sampling was used to collect data from 158 participants.
• Emotional well-being and engagement in cognitive reappraisal, problem solving, and appreciation were assessed.

Main Results:

• Significant interactions were found between the intervention and pre-test scores.
• Participants with lower baseline emotional well-being showed the greatest improvement.
• Individuals with lower engagement in appreciation strategies also benefited more.

Conclusions:

• Baseline levels of emotional well-being and specific emotion regulation strategies significantly moderate intervention effects.
• Interventions may be particularly beneficial for individuals with lower well-being or less adaptive strategy use.
• These findings underscore the importance of considering between-individual differences in intervention design and application.
