Emotion dysregulation and affective temperaments in opioid use disorder: a 1-year follow-up study

Opioid use disorder (OUD) remains a significant public health challenge with high recurrence rates and varied long-term outcomes. Affective temperament and emotion regulation have been identified as influencing addictive behaviors and treatment outcomes in OUD. However, limited research has explored their association with reversion over an extended period.

The EDATOUD (Emotion Dysregulation and Affective Temperaments in Opioid Use Disorder) study aimed to evaluate the effects of affective temperament and emotion regulation characteristics on recurrence over a 1-year follow-up period. The study aimed to compare the baseline characteristics of patients who achieved remission versus those who did not and identify potential predictors of recurrence risk.

The study included 63 patients with OUD who were assessed monthly for return-to-use through self-report, psychiatric examination, and urine analysis. Sociodemographic data, affective temperament, difficulties in emotion regulation, anxiety, and depression were measured at baseline. Statistical analyses were performed to compare the recurrent and remission groups and determine the predictive value of these clinical features on recurrence.

Within the one-year, 77.8% of patients returned to use. Affective temperament characteristics did not differ between the groups. However, the recurrent group patients exhibited significantly more difficulties in emotion regulation.

Difficulties in emotion regulation are associated with an increased risk of recurrence in patients with OUD. Understanding these factors can inform the development of tailored treatment strategies to improve long-term outcomes. Further research is needed to explore additional factors contributing to reversion and enhance intervention and support systems for sustained recovery in OUD.
