The Pattern of Structural Relationships of Relapse of Individuals with Substance Use Disorder based on Attentional Bias and Reward Sensitivity with the Mediating Role of Inhibition Control

The aim of this study was to investigate the pattern of structural relationships of relapse in individuals with substance use disorder based on attentional bias and reward sensitivity with the mediating role of inhibition control.

The present study was descriptive-correlation of structural equation modeling type. The statistical population of this study included all withdrawing substance-dependent individuals (methamphetamine) referred to addiction treatment centers in Ardabil in 2019. 172 individuals with methamphetamine use were selected by convenience sampling method using the Slovin formula. Participants answered the questionnaires of recurrence prediction and reward sensitivity, as well as the dot-probe and go/no-go tests. Pearsonchr('39')s correlation, structural equation modeling and bootstrapping were the methods used to analyze the data.

Results showed that there were significant positive or negative correlations between the research variables. The results confirmed the fit of the hypothesized research model. The results showed that attentional bias and reward sensitivity had significant direct effects on relapse and also indirect effects through inhibition control.

According to the results, it can be said that by adjusting for attentional bias and reward sensitivity, inhibition control reduces relapse in substance users. Therefore, it is recommended that addiction specialists use the results of the present study in their treatment programs.
