OBJECTIVE: Childhood maltreatment is widely accepted as a risk factor for drug addiction from adolescence to adulthood. However, the influence of childhood maltreatment on drug treatment related variables, such as drug abstinence motivation and self-concept, as well as self-efficacy, remains unclear. This study aims at exploring whether self-concept mediates the relationship between childhood maltreatment and abstinence motivation, as well as self-efficacy, among drug addicts.
METHODS: This study involves 816 (550 males, 226 females, mean age=34.59, range=16-58 years) drug addicts from compulsory detoxification units. Participants completed questionnaires, including the childhood trauma questionnaire 28 - item short form (CTQ - SF), Tennessee self-concept scale (TSCS), general self-efficacy scale (GSES), and drug abstinence motivation questionnaire (DAMQ).
RESULTS: The structural equation model (SEM) analysis, including total and specific forms of maltreatment scores, showed that childhood maltreatment was negatively associated with self-concept, self-efficacy, and abstinence motivation. Self-concept was positively associated with self-efficacy and abstinence motivation. Conversely, significant association between self-efficacy and abstinence motivation did not exist. An indirect analysis showed that self-concept mediated the relationship between childhood maltreatment and self-efficacy. Critically, self-concept arbitrated the relationship between childhood maltreatment and abstinence motivation. The indirect effect of self-concept between childhood maltreatment and abstinence motivation still existed when the total scores of maltreatment were replaced by the scores of specific forms of maltreatment.
CONCLUSIONS: These results demonstrated that self-concept is a critical factor in understanding the relationship between childhood maltreatment and abstinence motivation, as well as self-efficacy, among drug addicts. Improving the sense of self-worth may be an effective intervention therapy among drug addicts with childhood maltreatment history.
