Perceived Self-Control is Related to Mental Distress in Patients Entering Substance Use Disorder Treatment.
BACKGROUND
Levels of mental distress are high in patients with substance use disorders (SUD) and investigation of correlates may broaden our understanding of this comorbidity.


OBJECTIVES
We investigated self-reported symptoms of mental distress among individuals entering either outpatient opioid maintenance treatment (OMT) or other inpatient SUD treatment and related factors, with a particular focus on perceived self-control.


METHODS
A cross-sectional study including substance users (n = 548; mean age 34 years; 27% women) entering treatment at 21 different treatment-centers across Norway, interviewed between December 2012 and April 2015. Symptoms of mental distress were assessed with Global Symptom Index (GSI) score. Adjusted relative risk ratios (RRR) with 95% confidence intervals (CI) were estimated through multinomial logistic regression.


RESULTS
More than half of the participants in both treatment groups reported mental distress (GSI) above clinical cut-off. The use of alcohol and exposure to violence were associated with increased likelihood of high GSI for both patient groups. Also, lower perceived self-control was related to high GSI in both treatment groups.


CONCLUSION
Symptoms of mental distress were equally common among patients entering OMT and those entering other inpatient SUD treatment, even if the patients differed on a number of clinical characteristics. Use of alcohol and exposure to violence were associated with more mental distress in both groups. Perceived self-control also appeared to be important when explaining symptoms of mental distress among these SUD patients.
