The forty opioid users were divided into two groups: (a) the control group (
Demographic characteristicsThere was no statistically significant difference among both groups in terms of all subclasses of GHQ-28 and the total score before the intervention, except in terms of social dysfunction. However, the researchers observed a statistically significant difference in social dysfunction, anxiety, and insomnia, in addition to a difference in the GHQ-28 total score between the control and intervention groups after brief CBT. The results are shown in Table 
GHQ-28 scores and difference between groupsCBT: Cognitive Behavioral TherapyDue to the statistically significant differences among both groups in terms of occupation, marital status, and social dysfunction, the authors utilized the Poisson regression model. After adjusting the effect of occupation and marital status, the multiple Poisson regression model results revealed no statistically significant difference (

GHQ-28 scores and difference before and after interventionCBT: Cognitive Behavioral TherapyThe researchers applied a Likert scale for scoring, in which the cut-off score was determined to be 23. There was no statistically significant difference in terms of psychotic and non-psychotic opioid users in the intervention group before and after CBT (Table
