Levels and predictors of participation in integrated treatment programs for pregnant and parenting women with problematic substance use

Aims: The aims were to investigate whether baseline characteristics and problematic substance use were related to change in mental distress over time in patients with substance use disorders during an 18-year period. Method: This was a prospective, longitudinal study of patients followed for 18 years after entering specialised treatment for substance use disorders. A sample of 291 patients was recruited in 1997 and 1998. Mental distress was measured using the Hopkins Symptom Checklist 25 at baseline, and at six and 18 years. Lifetime psychiatric disorders and substance use disorders at baseline were measured using the Composite International Diagnostic Interview, while personality disorders were measured using the Millon Clinical Multiaxial Inventory II. At the six- and 18-year follow-ups, substance use was measured using the Alcohol Use Disorders Identification Test and the Drug Use Disorders Identification Test. Linear mixed model was estimated to assess the overall level of mental distress over 18 years for participants with complete data at baseline ( n = 232). Results: In an adjusted model, problematic substance use assessed simultaneously with mental distress, having lifetime affective, anxiety and personality disorder at baseline were associated with greater levels of mental distress over the 18-year period. The change in mental distress from baseline to the six-year, but not to the 18-year, follow-up was significantly larger among females than among males. Conclusion: The results suggests a reciprocal relationship over time between substance use and mental health problems. Also, there seems to be an additive effect between ongoing problematic substance use and lifetime mental disorders on greater levels of mental distress. This addresses the importance of integrated treatment for both substance use disorders and mental disorders to improve the long-term course for patients with these comorbid disorders.

Objective: The aim of this paper is to critically review the literature on major mental illness and problematic substance use in order to provide clinicians and policymakers with evidence to support proposed directions for management of the above. Method: The available literature was accessed using computerised databases and manual searching. Results: The predominantly North American-based literature is largely descriptive. Those studies which attempt empirical evaluation are limited by methodological weaknesses which include small sample sizes, short follow-up periods, inadequate measurement of substance use, lack of experimental design, and treatment drift over time. However, there is consensus among most studies regarding prevalence rates and treatment. Conclusions: Problematic substance use is the most common comorbid condition among people with a major mental illness and is associated with poorer patient outcomes. There is evidence to suggest that the integration of mental health and drug and alcohol services will result in improved detection, assessment and management of comorbidity. Integration refers to the provision of comprehensive services by a single service with staff who are competent in both mental health and drug and alcohol skills. A tolerant, non-confrontational approach to substance use is most appropriate for people with a major mental illness. Treatment programs need to recognise the longitudinal nature of substance abuse and dependence. More research needs to be conducted in this field in order to establish guidelines for effective management.
