ABSTRACT
The emotional disturbance of substance abusers is often described as an inability to identify and express feelings coupled with an excess vulnerability to experience negative affect. However, there is only limited empirical support for this perspective. To validate this description, we first defined components of alexithymia, hostility, and posttraumatic stress disorder (PTSD) derived from established measures of each by conducting confirmatory factor analyses based on a self-report data set from a clinical sample of 253 alcoholics and drug addicts. We then fashioned and tested overarching latent variables representing the three aspects of emotional dysfunction (i.e., alexithymia, hostility, and PTSD) and finally tested the correlations among these overarching variables. We found a strong association between a factor labeled Bottled-Up Emotions and another labeled Neurotic Hostility (r = .62) as well as an association between PTSD and Bottled-Up Emotions (r = .66). The structure, magnitude, and intercorrelation of the latent variables did not depend on the type of psychoactive substance abused. These results support the view that features of alexithymia and hostility coexist in substance abusers and that this joint deficit is part of a broad disturbance across multiple psychological domains including pathological response to traumatic stress.
