Objectives
Sober living houses are alcohol- and drug-free recovery residences that help individuals with substance use disorders maintain long-term abstinence. Given the prevalence of co-occurring mental disorders among individuals entering substance use treatment, it is likely that many residents entering sober living houses are also contending with psychiatric symptoms, and it is unclear how these symptoms may affect their sobriety. This study sought to describe the prevalence and trajectories of different types of symptoms among sober living house residents and examine how these symptoms affect substance use outcomes.
Methods
300 residents (241 men and 59 women, with a mean age of 38.5 years) were interviewed upon entry and re-interviewed at 6-, 12-, and 18-month follow-ups. Psychiatric symptoms were assessed using the Brief Symptom Inventory (BSI). General estimating equations were used to test changes in BSI global psychological distress and clinical symptom scales (depression, hostility, somatization, and phobic anxiety) over time and to test the relationship between scale scores and substance use in longitudinal models controlling for demographics, length of stay, and psychiatric service utilization.
Results
Psychiatric symptoms were common. At baseline, the majority (51%) of participants endorsed 20 or more symptoms. Overall psychological distress and symptoms of depression and phobic anxiety significantly improved over time. Rates of abstinence and days of use among those who reported using substances also improved over time. Overall distress and all symptoms dimensions measured were associated with a decreased likelihood of abstinence. Symptoms of somatization were associated with an increase in the number of days substances were used among those who reported use.
Conclusions
Psychological symptoms among sober living house residents improve over time, but they are risk factors for relapse, suggesting that additional support provided to residents with psychiatric symptoms could improve substance use outcomes.
