Emotion regulation in short-term dynamic therapy: Attachment-moderated changes and bidirectional temporal...

This study examined changes in emotion regulation difficulties during short-term dynamic psychotherapy and their temporal relationship with symptom change, considering attachment styles as potential moderators. Sixty-three patients with mild to moderate depression and/or anxiety underwent 16 weeks of supportive-expressive therapy. Emotion regulation difficulties, symptoms, and attachment styles were assessed using self-report measures. Contrary to hypotheses, no overall improvement in emotion regulation difficulties was observed. However, patients with high attachment avoidance showed increased emotional clarity, while those with anxious attachment demonstrated greater acceptance of negative emotions over time. A deterioration in emotion regulation strategies was observed across all patients, particularly among those with avoidant attachment. Cross-lagged panel analysis revealed complex temporal dynamics: bidirectional relationships between emotion regulation and symptoms during early sessions, decoupling in intermediate sessions, and unidirectional effects (regulation predicting symptoms) in late sessions. These findings highlight the complex phase-dependent dynamics of emotion regulation change in short-term psychodynamic psychotherapy. The results emphasize the importance of considering both treatment phase and attachment styles when addressing emotion regulation difficulties in therapy.
