This retrospective chart-review study examined patient-level correlates of initiation and completion of evidence-based psychotherapy (EBP) for posttraumatic stress disorder (PTSD) among treatment-seeking U.S. veterans. We identified all patients (N = 796) in a large Veterans Affairs PTSD and anxiety clinic who attended at least 1 individual psychotherapy appointment with 1 of 8 providers trained in EBP. Within this group, 91 patients (11.4%) began EBP (either Cognitive Processing Therapy or Prolonged Exposure) and 59 patients (7.9%) completed EBP. The medical records of all EBP patients (n = 91) and a provider-matched sample of patients who received another form of individual psychotherapy (n = 66) were reviewed by 4 independent raters. Logistic regression analyses revealed that Iraq and Afghanistan veterans were less likely to begin EBP than veterans from other service eras, OR = 0.48, 95% CI = [0.24, 0.94], and veterans who were service connected for PTSD were more likely than veterans without service connection to begin EBP, OR = 2.33, 95% CI = [1.09, 5.03]. Among those who began EBP, Iraq and Afghanistan veteran status, OR = 0.09, 95% CI = [0.03, 0.30], and a history of psychiatric inpatient hospitalization, OR = 0.13, 95% CI = [0.03, 0.54], were associated with decreased likelihood of EBP completion.

Both low and high utilization of psychotherapy for posttrauamtic stress disorder (PTSD) may be problematic. Low utilization may translate into patients receiving insufficient services to effect clinical change, whereas high utilization may lead to resource depletion as a disproportionate amount of available resources are focused on a small number of patients. This study examined rates and predictors of low and high psychotherapy utilization in a sample of 157 patients enrolled in an outpatient Veterans Affairs (VA) PTSD clinic. Approximately 25% of the sample were low users, receiving fewer than 4 sessions per year, whereas 16% were categorized as high users, receiving 52 or more therapy sessions per year during their course of treatment. Indicators of clinical severity, including comorbidity, global functioning, and number of inpatient admissions, were not associated with low versus high utilization. Age was the only clinical or demographic variable that independently predicted utilization, with older veterans using more services. Qualitative data indicated that social and relational factors, such as lack of social support, may contribute to utilization rates in veterans with PTSD.

Cognitive-behavioral therapy (CBT) is the treatment of choice for panic disorder (PD); however, the effectiveness of the treatment is often thought to be diminished in the presence of comorbid conditions. PD and posttraumatic stress disorder (PTSD) commonly co-occur in veteran populations, potentially complicating the effective treatment of each disorder. The individual presented in this case is a female veteran in her mid-50s who received treatment for PD and presented with significant comorbidities (PTSD, histrionic personality traits, major depressive disorder, and chronic suicidality). She participated in an intensive weekend treatment for PD that involved psychoeducation, cognitive restructuring, and interoceptive exposure. This case illustrates the challenges in implementing a manualized treatment for panic with a diagnostically complex veteran and the improvement in panic symptoms despite comorbid presentation.

Background:Cognitive behavioural therapy (CBT) for panic disorder encourages patients to learn about and make changes to thoughts and behaviour patterns that maintain symptoms of the disorder. Instruments to assess whether or not patients understand therapy content do not currently exist.Aims:The aim of this study was to examine if increases within specific knowledge domains of panic disorder were related to improvement in panic symptoms following an intensive 2-day panic treatment.Method:Thirty-nine Veterans enrolled in an intensive weekend panic disorder treatment completed knowledge measures immediately before the first session of therapy and at the end of the last day of therapy. Four panic disorder experts evaluated items and reached consensus on subscales. Subscales were reduced further to create psychometrically sound subscales of catastrophic misinterpretation (CM), behaviours (BE), and self-efficacy (SE). A simple regression analysis was conducted to determine whether increased knowledge predicted symptom change at a 3-month follow-up assessment.Results:The overall knowledge scale was reduced to three subscales BE (n = 7), CM (n = 13) and SE (n = 8) with good internal consistency. Veterans’ knowledge of panic disorder improved from pre- to post-treatment. Greater increase in scores on the knowledge assessment predicted lower panic severity scores at a 3-month follow-up. A follow-up analysis using the three subscales as predictors showed that only changes in CM significantly contributed to the prediction.Conclusions:In an intensive therapy format, reduction in panic severity was related to improved knowledge overall, but particularly as a result of fewer catastrophic misinterpretations.
