Modelling structural relations of craving based on sensitivity to reinforcement, distress tolerance and self-Compassion with the mediating role of self-efficacy for quitting

Background & Objectives:  Craving is a major barrier to the effective treatment of substance  addiction. This study conducted in order to Modelling structural relations of craving based on sensitivity to reinforcement, distress tolerance and self-compassion with the mediating role of self-efficacy for quitting. Materials and Methods: The method of this study was descriptive-correlational. The whole people with substance dependence referring to Ardabil centers of addiction treatment in the second half of 2018 comprised statistical population of this research. two hundred and forty-five people were selected from this population through multistage random cluster sampling and they were asked to respond to questionnaires of sensitivity to reward and punishment, Distress tolerance, self-compassion, self-efficacy for quitting and also craving. Data were analyzed by descriptive statistics, Pearson correlation coefficient and strucctral equating modeling (SEM) using Lisrel software. Results: The results of correlation coefficient indicated that craving with sensitivity to reward and punishment was positive and with negative total score of total Distress tolerance and its components, and with the total score of self-compassion and components (Kindness to oneself, common humanity and mindfulness), and negative self-efficacy There is a significant positive relationship with components (self-confidence, isolation, and overweight) Also, there is a negative relationship between self-efficacy for quitting sensitivity to reward and punishment and with the total score of Distress tolerance and its components, and with the total score of compassion for oneself and components (Kindness to oneself, common humanity and mindfulness), positive relationship and components (Self-confidence, isolation There is a negative and significant relationship between the two. The model fitness indexes confirmed the path of sensitivity to rewards and punishment, distress tolerance and self-compassion to the craving with the mediating role of self-efficacy for quitting.
