The Indirect Relationship Between Interpersonal Trauma History and Alcohol Use via Negative Cognitions in a Multisite Alcohol Treatment Sample.

Although interpersonal trauma history (ITH) is frequently associated with alcohol use disorder (AUD), little is known about specific psychological constructs that may indirectly link these phenomena. This study hypothesized that one such construct may be negative cognitive schemas that often emerge in the aftermath of trauma. Secondary latent variable modeling was conducted using the Project MATCH sample of adults receiving treatment for AUD (N = 1726; 24.3% women; 38.63% ITH). The negative cognitions latent variable provided an excellent fit to the data and showed evidence of strong measurement invariance. As hypothesized, negative cognitions mediated the inverse association between ITH at baseline and percent days abstinent from alcohol 12 weeks later. Findings suggest that negative cognitions may be a specific underlying mechanism and potential treatment target for individuals with ITH and AUD.
