Effectiveness of Cognitive Processing Therapy for Male and Female U.S. Veterans With and Without Military Sexual Trauma.

Military sexual trauma (MST) affects approximately 2% and 36% of male and female veterans, respectively, (e.g., Allard, Gregory, Klest, & Platt, 2011). Although the deleterious consequences of MST have been clearly established, few studies have explored treatment effectiveness for this population. Using archival data from a residential treatment program, the current study explored the effectiveness of cognitive processing therapy (CPT) in treating full or subthreshold posttraumatic stress disorder (PTSD) to compare U.S. veterans reporting an MST index trauma (MST-IT) to those without MST-IT. Of the 481 participants, 40.7% endorsed MST-IT. Multiway frequency analyses were utilized to compare men and women with and without MST on baseline demographic variables. Hierarchical linear models were constructed to investigate treatment outcome by MST status and sex. Results showed that 44.8%, 23.8%, and 19.6% of the variation in clinician- and self-reported PTSD and depression symptoms were explained by three models. Scores on all outcome measures significantly decreased over time for both groups. Additionally, women demonstrated a sharper decrease in PTSD symptoms over time than men. Lastly, men who reported MST-IT had higher PTSD symptoms than men without MST-IT on average. With no control group or random assignment, preliminary findings suggest residential treatment including CPT may be effective for MST-IT regardless of sex.

A randomized clinical trial of cognitive processing therapy for veterans with PTSD related to military sexual trauma.

In this randomized controlled clinical trial, the authors evaluated the effectiveness of cognitive processing therapy (CPT) in the treatment of self-reported and clinician-assessed posttraumatic stress disorder (PTSD) related to military sexual trauma (MST), along with depressive symptoms. Eighty-six veterans (73 female, 13 male) randomly assigned to receive 12 individual sessions of either CPT or present-centered therapy (PCT) were included in analyses. Blinded assessments occurred at baseline, posttreatment, and 2, 4, and 6 months posttreatment. Mixed-effects model analysis revealed a significant interaction between groups (p = .05, d = -0.85): At posttreatment, veterans who received CPT had a significantly greater reduction in self-reported, but not clinician-assessed, PTSD symptom severity compared to veterans who received PCT. All three primary outcome measures improved significantly, both clinically and statistically, across time in both treatment groups. Pre- and posttreatment effect sizes were mostly moderate to large (d = 0.30-1.02) and trended larger in the CPT group. Although the study was impacted by treatment fidelity issues, results provide preliminary evidence for the effectiveness of CPT in reducing self-reported PTSD symptoms in a population of veterans with MST, expanding on established literature that has demonstrated the effectiveness of CPT in treating PTSD related to sexual assault in civilian populations.

The effect of childhood sexual assault history on outpatient cognitive processing therapy for military sexual trauma-related posttraumatic stress disorder: A preliminary investigation.

History of childhood sexual assault (CSA) may result in poorer emotion regulation and interpersonal functioning, potentially affecting the tolerability and effectiveness of evidence-based treatments (EBTs) for posttraumatic stress disorder (PTSD). Survivors of military sexual trauma (MST) have an increased incidence of CSA; however, research examining the role of CSA in EBTs for veterans with MST-related PTSD is limited. Data from 32 (9 male; 23 female) veterans with MST-related PTSD were used from a previously conducted randomized clinical trial examining the efficacy of an outpatient PTSD EBT (i.e., cognitive processing therapy [CPT]). Self-rated PTSD symptom severity was assessed at pretreatment, during treatment, and up to 6 months following treatment completion. Number of CPT sessions attended and treatment completion were also examined. Using a hierarchical linear modelling approach, results indicated both veterans with and without a history of CSA were found to benefit from CPT, and history of CSA did not significantly predict treatment response. Additionally, number of sessions attended and treatment completion did not significantly vary based on history of CSA. These preliminary findings provide support for the tolerability and efficacy of outpatient CPT in veterans with MST-related PTSD regardless of CSA history.
