Abstract
Objective To analyze the role of sleep quality (SQ) in quality of life (QOL) of heroin addicts receiving methadone maintenance treatment (MMT). Methods A total of 603 heroin addicts completed the socio-demographic questionnaire, Pittsburgh Sleep Quality Index (PSQI), and the World Health Organization’s Quality of Life Questionnaire-Brief Version (WHOQOL-BREF). Hierarchical Multiple Linear Regression was used to examine the unique contribution of SQ in the explanation of QOL. Results The overall unique contributions of the seven components in PSQI, measured by △R2, ranged from 0.139 to 0.216, which could account for 41.3%~55.7% of the total explainable variance in the four domains of WHOQOL-BREF. Conclusion SQ is an important predictor of QOL in heroin addicts receiving MMT.QOL can be improved through the intervention of low SQ. Key words: Methadone maintenance treatment; Heroin addiction; Sleep quality; Quality of life
