The dynamic contribution of stressful life experiences in predicting psychiatric comorbidity continues to challenge clinical practice and research. This study tested incremental validity of stressful life experiences related to psychiatric comorbidity among 128 young women in a Midwestern substance abuse treatment facility. Respondents reported low income, homelessness, and health and mental health issues. Using the Addiction Severity Index (ASI), Diagnostic and Statistical Manual of Mental Disorders-Fourth Edition, Text Revision, and Stressful Life Experience (SLE) Screen as correlates, hierarchical linear regression demonstrated support for incremental validity of SLE uniquely accounting for 6.5% of variance in ASI psychiatric scores. Findings support future use of SLE in clinical settings for assessment and intervention purposes.
Bibliographical noteFunding Information:
The study findings were predominantly in the direction as hypothesized, with increased numbers of stressful life experiences depicted on the SLE Screening resulting in an increase in the ASI psychiatric composite score. The hypothesis pertaining to SLE containing incremental validity was supported by the increase in the variance in
