The aims of the present study were to identify empirically derived drinking motive and personality typologies to determine whether these typologies differ as a function of PTSD status (i.e., nontrauma control, trauma exposed-no PTSD, and PTSD) and to evaluate associations between typology and PTSD symptom severity and alcohol consumption, respectively. Cluster analyses identified a 4-cluster solution. Results indicated that these typologies differed significantly according to trauma group as well as across levels of PTSD symptom severity and alcohol use. Specifically, Cluster 4 represented individuals at highest risk for both PTSD symptom severity and alcohol use compared to all the other typologies; Cluster 1 demonstrated lowest risk for PTSD symptom severity and alcohol use compared to all other typologies; and although Clus...Continue Reading
