OBJECTIVE: There is a high rate of comorbidity among substance dependence, depression, and physical health problems. This study aimed to examine the impact of pre-treatment physical health stressors (acute and chronic conditions) on outcomes of treatment in a sample of veterans with dual disorders (depression and substance dependence) who were randomized to integrated cognitive behavioral therapy versus 12-Step interventions. METHODS: This study included 205 veterans (89.8% male, mean age = 49.5 years) enrolled in a clinical treatment outcomes trial. Chronic health problems (persistent, ongoing conditions lasting 2 weeks or more; e.g., arthritis, diabetes) and acute health events (occurring on a discrete date; e.g., injury, surgery, myocardial infarction) were coded dichotomously (presence versus absence) and evaluated separately. The impact of physical health stressors on abstinence (defined dichotomously), percentage of days abstinent, and depression symptoms were analyzed at the end of 12 and 24 weeks of treatment. Additionally, associations between intake motivation to change, health stressors, and substance use were examined. RESULTS: Analyses revealed that participants who had experienced a pretreatment acute health event had higher rates of abstinence at 12-weeks, higher percentage of days abstinent at 24-weeks, and higher depression symptoms at intake. Participants with chronic health difficulties had more severe depression at intake and those participants with severe chronic difficulties had greater depression symptoms across all time points. Chronic health difficulties were related to the Taking Steps factor of motivation to change substance use, but acute health events were not related to motivation to change. Motivation to change was also not related to substance outcomes in our sample. CONCLUSIONS:Physical health appears to have a complex relationship with co-occurring depression and substance dependence. Acute health problems predicted lower substance use, whereas chronic health problems were associated with higher depression levels. Explicitly addressing the connection between substance use and health events during treatment may improve addiction treatment outcomes. However, individuals with chronic health problems may benefit from extending treatment or adjunct strategies focused on addressing chronic health concerns. This is an analysis of data collected as part of a clinical trial registered at www.ClinicalTrials.gov as NCT00108407.
