Abstract
Background: Anxiety, a major factor that affects the therapeutic effect and dropout rate of methadone maintenance treatment, has a high prevalence among MMT users. This study aims to investigate the prevalence of anxiety in MMT users and explore the main influencing factors of anxiety of methadone maintenance treatment users.
Methods: 177 methadone maintenance treatment users in Guangzhou, China were evaluated. The socio-demographic, duration and MMT-related characteristics were documented. Anxiety, quality of life and sleep quality were evaluated by Beck Anxiety inventory (BAI), the Quality of Life-Drug Addiction (QOL-DA) and Pittsburgh Sleep Quality Index (PSQI) respectively. The correlation between different factors and BAI score was also analyzed.
Results: The BAI total score, QOL-DA score, PSQI score were 7.1±8.2, 163.5±21.4, 6.0±4.0 respectively. 30.5% of the subjects showed mild to severe anxiety. Treatment interruption, QOL-DA score and PSQI score had strong correlations with the score of BAI, with correlation coefficients of 0.17, -0.08 and 0.50 respectively.
Conclusions: Anxiety symptoms were commonly presented in MMT users. Treatment interruption, quality of life and sleep quality are the major factors affecting anxiety of MMT users.
