Abstract
BACKGROUND: Enhancing abstinence motivation of drugs is an effective strategy for the rehabilitation of people who used drugs and prevention of drug use relapse. However, little is known about its risk and protective factors. This study aimed to examine the potential intrapersonal (ie, impulsivity, depression, anxiety, sleep quality) and interpersonal factors (ie, perceived social support) of abstinence motivation among people who completed the community rehabilitation treatment. METHODS: A total of 222 participants (mean age = 43; male = 89.2%) were recruited from eleven communities located in Wenzhou, China. Data were collected using a self-reported questionnaire in counselling room settings between April and June 2021. RESULTS: The proportions of participants with depression, anxiety, and poor sleep quality were 38.8%, 19.5%, and 21.2%, respectively. Age and family history of physical disease were significant background factors of abstinence motivation. Impulsivity, depressive symptoms, anxiety symptoms, and poor quality of sleep were negatively associated with abstinence motivation. Perceived social support from family and important others was positively associated with abstinence motivation. Structural equation modeling fitted the data well in which impulsivity and perceived social support were both associated with abstinence motivation indirectly through mental health problems. CONCLUSION: The identified psychosocial factors should be addressed in community rehabilitation treatment and follow-up service to enhance abstinence motivation and the long-term effectiveness of the treatment.
