DescriptionThere is a well-established body of literature that supports that individuals with substance use disorders are at-risk of being diagnosed with a comorbid mental health disorders (Lai et al, 2015). These disorders complicate treatment and impact treatment outcomes. The purpose of this study was to explore clinical features and disorders in an adult male inpatient population. Data were collected from 45 patients in a drug and alcohol rehabilitation facility. Research utilized measures of anxiety, depression, trauma, impulsivity and coping responses in addition to a demographic questionnaire, in order to assess descriptive features and pathology in the population. Bivariate correlations were computed to assess the relationship between the clinical disorders and diagnostic features. Results indicated high associations (p<.01) between the clinical disorders that were measured: depression, anxiety, and trauma. In terms of clinical features that were measured, impulsivity was positively correlated (p=<.01) with all clinical disorders (depression, anxiety, and trauma). Finally, trauma scores were positively correlated with avoidant coping responses. Limitations to the study include sample size, correlational design, and the design of the study (one-shot as opposed to pre-posttest). Implications based on this research such as importance of assessment of mental health problems in inpatient facility and staff training's are discussed.
