Methods: Participants in this study (N = 103) were residents of a re-entry program using Helping Women Recover([HWR], Covington, 1999), a program designed for women with substance use disorders and trauma history. These data were gathered prior to the intervention. Trauma was measured with the Trauma Symptoms Inventory (TSI; Briere, 1996). We focused on the following TSI subscales: Anxious Arousal, Depression, Anger/Irritability, Intrusive Experiences, Defensive Avoidance, Dissociation, Sexual Concerns, Dysfunctional Sexual Behavior, Impaired Self-reference, and Tension Reduction Behavior. Readiness to change was measured with the University of Rhode Island Change Assessment (URICA; McConnaughy, Prochaska, & Velicer, 1983) and is made up of the following subscales: Precontemplation, Contemplation, Action, and Maintenance.
Results: LPA resulted in a two-class solution (AIC = 6117.965, 6199.642, Entropy= .968; LMR=528.84, p<.001). Class 1 (57.3%; n=59) included women with high levels of trauma across all indicators. Class 2 (42.7%; n= 44) demonstrated notably lower levels of trauma indicators. Demographics were not significantly different across subgroups of women. However, age trended toward significance (p=.06) demonstrating that younger women had lower levels of trauma (i.e., Class 2). There was a significant difference between classes with respect to the Precontemplation subscale of the URICA with Class 1 (i.e., higher trauma) demonstrating higher precontemplation than women in Class 2 (i.e., lower trauma) (p=.029). Women with higher trauma in Class 1 also demonstrated a trend toward greater action than women in Class 2 (p=.071). URICA Readiness to change scores were slightly higher for women with more trauma in Class 1, but the difference was non-significant.
Implications: Findings illustrate a first step in demonstrating the link between trauma indicators and readiness to change; women in Class 1, who experienced more trauma, were both more ambivalent and more likely to address their problematic behaviors when compared to Class 2. These results point to a need to further delineate links between trauma and readiness to change, which has implications for administrators delivering evidence-based treatment. Findings that illustrate extremes of readiness among individuals with high trauma suggest a need to tailor interventions to include motivational components that are also trauma-informed.
