Leveraging observational data to identify in-session patient and therapist predictors of cognitive processing therapy response and completion.

Cognitive processing therapy (CPT) is an evidence-based treatment for posttraumatic stress disorder (PTSD), but little is known about in-session process variables that predict symptom reduction and treatment completion during CPT. Examining potentially malleable factors that may promote or impede recovery can inform care delivery and enhance outcomes. The current study used observational ratings of CPT session recordings to examine in-session patient and therapist factors in cognitive, affective, and interpersonal domains to identify their relative contributions to predicting symptom outcomes and treatment completion. Participants were 70 adult survivors of interpersonal violence who received CPT. Predictors of better posttreatment PTSD outcomes included less patient fear, ß = .32, and less patient avoidance of engaging with the therapist, ß = .35. When using the last available PTSD score, less fear, ß = .23, and avoidance, ß = .28, continued to predict better outcomes, and more patient cognitive flexibility emerged as a stronger predictor of outcome, ß = -.33. Predictors of a higher likelihood of treatment completion included more therapist use of Socratic dialogue, OR = 6.75, and less therapist encouragement of patient affect, OR = 0.11. Patient sadness and anger and therapist expression of empathy did not predict symptom outcomes or treatment completion versus dropout. The results highlight the importance of patients' cognitions, emotions, and engagement with their therapist in CPT as well as the role of therapist behaviors in patient completion of treatment.

Evaluating the relative contribution of patient effort and therapist skill in integrating homework into treatment for posttraumatic stress disorder.

OBJECTIVE: Homework has historically been an integral component of cognitive behavioral interventions for posttraumatic stress disorder (PTSD). Previous studies differ in the measurement of therapy homework, resulting in inconsistent conclusions about its contributions to symptom reduction. Given the methodological burden associated with examining therapist skill within sessions, there has been no research evaluating the impact of both therapist and patient efforts on homework within and outside of the therapy session across protocols. METHOD: We first examined the relative contribution of four homework-related variables to treatment outcomes of survivors of interpersonal violence (12 sessions; 58 survivors) diagnosed with PTSD and treated with cognitive processing therapy (CPT) in two randomized, controlled clinical trials. We then assessed the moderating effect of therapist competency in the homework element of CPT on these associations by examining therapist skill in 544 therapy sessions scored by independent raters. RESULTS: Perceived helpfulness of assignments emerged as the only significant predictor of PTSD symptom reduction (ß = 0.48). Therapist homework competency moderated the relationship between time spent on homework and treatment outcome, such that more time spent on homework was associated with significantly poorer treatment response at low levels of therapist homework competency. CONCLUSIONS: Results suggest that patients' understanding of the direct contribution of homework to recovery is critical for increasing the effectiveness of the homework component of therapy. Therapist skill in incorporating homework effectively into the protocol is variable. It is essential that therapists ensure that patients' efforts (e.g., time dedicated to the task) are yielding clear results and perceived as fruitful.

Psychotherapy Utilization, Preferences, and Retention among Women Veterans with Post-traumatic Stress Disorder.

BACKGROUND: Psychotherapy is the gold standard treatment for post-traumatic stress disorder (PTSD), yet psychotherapy use and retention among veterans is low. Little is known about the barriers to care and factors associated with women veterans' PTSD psychotherapy use and retention. Using a nationally representative sample of 986 women Veterans Health Administration primary care users with PTSD and a perceived need for mental health care, we examined 1) the proportion of women who used psychotherapy, 2) retention in psychotherapy among women who used any psychotherapy, and 3) individual factors related to psychotherapy use and retention. METHODS: Women completed a survey on their mental health care experiences. Outpatient mental health care use in the year before the survey was obtained from Veterans Health Administration administrative data. RESULTS: Most women (79.1%) used psychotherapy, and 41.7% of those women had a minimal therapeutic dose of psychotherapy (≥8 visits). Mental health diagnostic comorbidity and being African American/Black or identifying as neither African American/Black nor White were significantly associated with higher psychotherapy use. Mental health diagnostic comorbidity, exposure to military sexual trauma, and receiving treatment aligned with gender-related and group-related preferences were associated with higher psychotherapy retention. Being a parent was associated with lower retention. CONCLUSIONS: Although a significant proportion of women veterans with PTSD are using psychotherapy, retention is enhanced when women are able to obtain treatment aligned with their preferences. Thus, efforts to promote patient-centered, shared decisions regarding mental health treatment options could increase the efficacy and efficiency of treatment for PTSD among women.

Fidelity to the Cognitive Processing Therapy Protocol: Evaluation of Critical Elements.

The contributions of individual therapy elements to the overall efficacy of evidence-based practices for the treatment of posttraumatic stress disorder (PTSD) are not well-understood. This study first examined the extent to which theoretically important treatment components of Cognitive Processing Therapy (CPT; i.e., skill in Socratic questioning; prioritizing assimilation; attention to practice assignments; emphasis on expression of natural affect) were successfully administered across the course of therapy for 68 PTSD-positive survivors of interpersonal trauma. Therapist fidelity in the administration of these four elements was evaluated in 533 taped CPT sessions of study participants included in one of two randomized controlled CPT treatment trials. Second, we examined therapist fidelity to these components as a predictor of session-to-session PTSD and depression symptom change. Third, follow-up analyses examined the influence of high therapist competence for these four components across an entire course of therapy on symptom change from pre- to posttreatment. Results showed consistently high adherence and more variable competence for these four treatment components. There were no significant effects of therapist fidelity on session-to-session symptom change. However, results showed that overall high therapist competence for "skill in Socratic questioning" and "prioritizing assimilation before overaccommodation" were related to greater client improvement in PTSD severity, but "attention to practice assignments" and "emphasis on expression of natural affect" were not. Overall competence ratings for the four components were not significantly associated with improvement in depressive symptoms. Findings contribute to increased understanding of the relationship between the key treatment components of CPT and symptom change.

Heart-Focused Anxiety in Patients With Noncardiac Chest Pain: Structure and Validity.

Heart-focused anxiety (HFA) is a fear of cardiac sensations driven by worries of physical health catastrophe. HFA is impairing and distressing and has been shown to disproportionately affect individuals with noncardiac chest pain (NCCP), chest pain that persists in the absence of an identifiable source. The Cardiac Anxiety Questionnaire (CAQ) is a measure designed to assess HFA. The aim of this study was to evaluate the psychometric properties and factor structure of the CAQ in a sample of 229 adults diagnosed with NCCP. Results demonstrated that the CAQ is a useful measure of HFA in patients with NCCP and that a four-factor model including fear of cardiac sensations, avoidance of activities that elicit cardiac sensations, heart-focused attention, and reassurance seeking was the best fit for the data. Additionally, associations between CAQ subscales and two measures of health-related behaviors-pain-related interference and health care utilization-provided evidence of concurrent validity. Treatment implications are also discussed.
