The strong comorbidity of psychiatric and substance use
disorders is well documented outside of China, however it has not been studied
extensively among drug using individuals in China. This study evaluated
patterns of co-occurring psychiatric and substance use disorders among heroin
dependent individuals in Changsha, China.
Participants were 1002 individuals consecutively admitted
between March 10 and October 30, 2008 into two compulsory and one voluntary
drug rehabilitation centers in Changsha. The Structured Clinical Interview for
DSM-IV-TR Axis I Disorders-Patient Edition (SCID-I/P) and the Structured
Clinical Interview for DSM-IV-TR Axis II personality Disorders (SCID-II) were
used.
Mental health disorders were highly prevalent among study
participants: 29.6% had at least one lifetime DSM-IV Axis I and 19.5% had at
least one current (past month) Axis I mental health disorder. Antisocial
(40.7%) and Borderline (22.6%) Personality Disorders were most prevalent DSM-IV
Axis II lifetime diagnoses and a mood disorder (19.1%) was the most prevalent
Axis I lifetime disorder; 57.8% had other substance use disorder in addition to
opioid dependence. Study results indicate that females in compulsory settings
have lower socio-economic status than males in compulsory settings, and that
males in compulsory settings have higher rates of co-morbidities, including
personality, mood disorders, substance use co-morbidities, and lower
socio-economic status than males in the voluntary setting.
The study findings suggest an urgent need to expand and
improve diagnostic and treatment capabilities in compulsory rehabilitation
settings in China and a need for additional services and interventions specific
for female rehabilitants.
