Abstract
Background & Objectives: Substance abuse has undoubtedly affected many individuals and families in the country, and this is not an issue that can be ignored or considered unimportant. Studies have shown that good emotion regulation protects people from experiencing a wide range of adversities and mental health problems. Emotion regulation is an important variable in increasing or decreasing psychological well–being in people. It also seems that the relationship between difficulty in emotion regulation and psychological well–being sometimes occurs due to the mediating role of self–control. On the other hand, emotion regulation, well–being, and self–control are important variables related to people with substance abuse, and studies have shown a decrease in these variables in these people. Therefore, research on variables related to addiction and substance abuse is one of the obligations of every country and contributes to the individual and social development of that country. The present study aimed to determine the mediating role of self–control in the relationship between difficulty in emotion regulation and psychological well–being in men with substance abuse.
Methods: This research method was correlational based on structural equation modeling. The research population included all the men with substance abuse who were referred to addiction treatment centers in Rasht City, Iran, for treatment of their addiction within three months (May to July 2024). A total of 264 qualified volunteers of this population were included in the study by the purposive sampling method according to the inclusion and exclusion criteria. The inclusion criteria included participants' satisfaction, age range between 24 and 40 years, male only, recently detoxified (maximum one month), and education level of at least reading and writing ability. The exclusion criteria included failure to complete the questionnaire, severe physical and mental disorders such as psychosis, bipolar disorder, or borderline personality disorder (self–report), and excessive use of antipsychotic and neuroleptic drugs (benzodiazepines). The instruments used in this research were the Psychological Well–Being Scale (Ryff & Keyes, 1995), the Difficulties in Emotion Regulation Scale (Gratz & Roemer., 2004), and the Brief Self–Control Scale (Tangney et al., 2004). The Pearson correlation coefficient and structural equation method were performed in SPSS version 26 and AMOS version 24 at a significance level of 0.05 to analyze the data.
Results: In the fitted model, the direct effect of the difficulty in emotion regulation with psychological well–being (b= –0.37, p<0.001) was negative and significant; the direct effect of the self–control with psychological well–being (b=0.16, p=0.024) was positive and significant. Also, the direct effect of difficulty in emotion regulation with self–control (b= –0.50, p<0.001) was negative and significant. Further, the indirect effects of self–control in the relationship between difficulty in emotion regulation and psychological well–being (b= –0.08, p<0.05) were negative and significant. The collected data showed that the model has a good fit (RMSEA=0.04, χ2/df=1.49, CFI=0.96, GFI=0.97, IFI= 0.98, AGFI=0.95, TLI= 0.95).
Conclusions: According to the results, the mediating role of self–control in the relationship between difficulty in emotion regulation and psychological well–being in men with substance abuse was confirmed. Therefore, the results of this study may be a promising finding to improve the conditions of people with substance abuse so that practical steps can be taken to reduce and prevent the anomalies and injuries of the future generation of society.
