Current substance use will be assessed at baseline; this in consideration of the investigators' previous work demonstrating a link between active substance use and difficulties obtaining work for Veteran with mental illness receiving SE services (Kukla, McGuire, & Salyers, 2015). In addition, substance abuse may hinder participants from benefiting from the CBTw intervention. The investigators will use the recent substance use section of the Addiction Severity Index (ASI; McClellan, Luborsky, & Woody, 1980), which assesses use of a variety of substances in the previous 30 days.
