Changes in suicidal ideation following cognitive processing therapy in a VA residential treatment program

In 2015, suicide accounted for over 44,000 deaths and was the 10th leading cause of mortality in the US. Although Veterans, in general, are at a high risk for suicide, Veterans with Posttraumatic Stress Disorder (PTSD) are at even greater risk. While evidence suggests that PTSD symptoms are reduced by Cognitive Processing Therapy (CPT), little is known about how this treatment impacts changes in suicidal ideation across residential treatment. Studies with active duty personnel have found reductions in suicidal ideation following CPT treatment; however, only one study to date has examined this question in a Veteran sample. The current study examined (a) changes in suicidal ideation across a residential CPT treatment program and (b) the influence of demographic variables on change in suicidal ideation across treatment. Participants (N = 303) were admitted to a residential PTSD treatment in a VA medical center and completed pre-, mid-, and post-treatment assessments. Multilevel modeling of archival data revealed that suicidal ideation significantly decreased over the course of CPT (B = -0.153, SE =0.028, 95%CI =[-0.21, -0.10], t= -5.40, p< .001); however, this change did not differ based on age, marital status, sex, or race/ethnicity. Clinical and research implications are discussed.
