Objectives: Difficulty in emotional regulation is an important component in the pathology of different types of addiction and its evaluation can be helpful in understanding and treating these difficulties. The purpose of this study is to evaluate emotional regulation in people with opioid dependence (heroin and opium), food addiction, and internet addiction compared to normal people.
Methods: This is a causal- comparative study. Participants were 120 eligible male addicts selected using a purposive sampling method and divided into four groups of 30 including drug addiction, food addiction, internet addiction, and control. Semi-structured clinical interview for DSM-IV axis I disorders, Yale Food Addiction Scale, and Young’s Internet Addiction Test were used to diagnose the addictions. Then the Difficulties in Emotion Regulation Scale (DERS) was completed. Multivariate Analysis of Variance (MANOVA) was used to analyze the collected data.
Results: Overall DERS score and the score of its subscales were higher in all three addiction groups compared to the control group, and this difference was statistically significant (P<0.05). There was no significant difference between the three addiction groups in subscales of “unwillingness to accept certain emotional responses” and “difficulty engaging in goal-directed behavior”, but a significant difference between the three addiction groups was observed in subscales of “difficulty controlling impulse”, “lack of emotional awareness”, “lack of access to strategies”, “lack of emotional clarity”, and overall DERS score (P<0.05).
Conclusion: Men with opioid dependence, internet addiction and food addiction have more difficulties in emotional regulation compared to their normal peers. Emotional regulation ability in men with internet addiction is greater than in those with food and opioid addictions.
