Emotion Dysregulation and Affective Temperaments in Opioid Use Disorder: the preliminary results of a prospective...

Substance use disorder is a growing health problem all over the world. The coexistence of substance misuse, affective temperaments, and emotion dysregulation has not been studied sufficiently.

The present study aimed to evaluate the role of affective temperaments and emotion dysregulation on substance use disorder. The Emotion Dysregulation and Affective Temperaments in Opioid Use Disorder study was designed observational. This paper presents only the baseline assessments of the patient and control groups. One-year remission rates of the patients' group will be reported elsewhere after 1-year follow-up.

Sixty-seven patients with opioid use disorder and 68 healthy controls enrolled. All participants were administered to The Structured Clinical Interview for DSM-5, Temperament Evaluation of Memphis, Pisa, Paris, San Diego Autoquestionnaire, Difficulties in Emotion Regulation Scale, Beck Anxiety Inventory, and Beck Depression Inventory.

Patients with opioid use disorder had higher scores from all temperamental scales and showed higher difficulties on emotion regulation than the control group. Even controlling the confounding effects of anxiety and depression levels, dysthymic and anxious temperament scores were found correlated with the emotion dysregulation score in the patient group.

The emotional traits (i.e., affective temperaments) and emotion regulation abilities play a crucial role in substance use disorder. While managing substance use disorder, being aware of affective temperament characteristics and/or interventions to improve emotion regulation skills may be helpful.
