Objective:
This study was to investigate quality of life (QoL) among heroin
users receiving the methadone maintenance treatment (MMT) in Taiwan, and to
explore the QoL-associated factors.
Method::
In this study, we enrolled 781 her-oin users who were participating in the MMT programs at Tsaotun Psychiatric
Center in central Taiwan. We used the World Health Organization Quality of Life-Short Form (WHOQOL-BREF) Taiwan version for assessing their QoL. The Cen-ter for Epidemiologic Studies Depression Scale, the Barratt Impulsiveness Scale,
the Chinese Version of the Severity of Dependence Scale, and the Family APGAR
score were used to evaluate comorbid depressive symptoms and other characteris-tics. Blood tests for related infectious disease were also conducted. ANCOVA sta-tistics was used to identify significant associated factors independently linked to
poorer QoL after adjusting for confounders.
Results:
The mean participant age
was 36.0 years and most patients (90.9%) were men. Comorbid HIV infection was
found in 20.7% of heroin-dependent patients and hepatitis C virus infection was
common (90.5%). Unemployment was significantly and negatvely linked to the
physical, psychological, social, and environmental domains of QoL (p< 0.05 or p
< 0.01) . Needle-sharing and polysubstance abuse presented lower scores in the
physical domain. Impulsivity was significantly associated with a poorer psycho-logical domain of QoL (p< 0.01). Better family support had a significant positive
effect on the environmental parameters of QoL (p< 0.01). Depression was signifi-cantly associated with lower scores in all four domains of QoL after controlling
demographic characteristics, drug use, and comorbid infectious disease variables
(p< 0.05 or p< 0.01).
Conclusion:
The study findings show the associated factors
of QoL among heroin users. The presence of depression was found to negatively
influence QoL of heroin-dependent patients. Further studies are required to exam-ine the effect of alleviating these factors (e.g., depression) on heroin users’ QoL.
