Abstract:

Many Veterans who complete prolonged exposure (PE) or cognitive processing therapy (CPT) report residual symptoms, but it is unclear how to best address the mental health needs of these individuals. Examining patterns of mental health service utilization following completion of these two treatments may provide insight into how to best serve this group of individuals. In a large cohort of Veterans (N? = 12,514) who sought treatment in the Veterans Health Administration during Fiscal Years 2015-2019, logistic regression models were used to assess the odds of initiating an additional course of trauma-focused (i.e., PE or CPT) or depression-focused psychotherapy in the year following completion of PE or CPT based on demographic, psychiatric, and treatment effectiveness-related variables. Approximately 9% of Veterans engaged in either trauma-(6%) or depression-(3%) related psychotherapy in the year following discharge from PE or CPT. Factors associated with increased odds of trauma-focused treatment initiation included having a sleep disorder diagnosis (OR? = 1.23), a substance use disorder diagnosis (OR? = 1.27), or experiencing military sexual trauma (OR? = 1.64). Factors associated with increased odds of depression-focused treatment initiation included having a depression diagnosis (OR? = 2.02). This study suggests that certain subgroups of Veterans who engage in PE or CPT (e.g., Veterans with comorbid sleep or substance use problems) are more likely to seek additional evidence-based treatment and may require augmentations to maximize clinical benefits, either during the initial course of treatment or subsequent to PTSD treatment.
