Efficacy of Co-occurring Disorder (COD) Intervention in Patients with Methamphetamine Induced Psychosis

Abstract

Objective : To compared the efficacy of co-occurring disorder intervention (COD
intervention) versus treatment as usual on continuing amphetamine abstinence and
readmitted in 90 days among patients with methamphetamine induced psychosis.
Methodology : A randomized control trial was conducted. The samples consisted of
44 methamphetamine induce psychosis patients who admitted in Nakhon Phanom
Rajanagarindra Psychiatric Hospital. Samples were matched pair by sex, the severity
of psychotic and stage of change. Samples allocated by simple random sampling into
the experimental and control group. The experimental group assigned to co - occurring
intervention consisted of 12 sessions for 2 weeks compare the control group
assigned treatment as usual. The primary outcomes were assessed by continuing
methamphetamine abstinent behavior and readmitted in 90 days after completed
intervention. Descriptive and inferential statistics were used in data analysis.
Results : The experimental group had significantly more patients in continuing
methamphetamine abstinence and non-readmitted in 90 days after completed
intervention than the control group; 94.95 % of experimental group compared to 77.7%
of control group p <.05 (c2 =4.25,p =.039)
Conclusion : This study demonstrated that COD intervention was more efficacious than
treatment as usual in continuing methamphetamine abstinence and non-readmitted
in 90 days among methamphetamine induced psychosis patients. This program can
be applied to use in other areas depend on its context. For further study, longitudinal
study with large samples size is needed for follow up long term outcomes regarding
to abstinence
