A Theory of Planned Behavior Scale for Adherence to Trauma-Focused Posttraumatic Stress Disorder Treatments.

Evidence-based psychotherapies for posttraumatic stress disorder (PTSD), such as cognitive processing therapy and prolonged exposure (CPT/PE), greatly reduce suffering for veterans, but many veterans fail to complete treatment. Developing a theory-based understanding of adherence is necessary to inform interventions to improve treatment retention. We developed and tested a series of scales applying the theory of planned behavior (TPB) to CPT/PE adherence. The scales were administered in mailed surveys as part of a larger mixed-methods study of veteran adherence to PE/CPT. Surveys were sent to 379 veterans who were initiating CPT/PE across four U.S. Veterans Affairs (VA) hospitals and 207 of their loved ones. Subsequent session attendance and homework compliance were coded via a review of electronic medical records. We examined item-level characteristics, factor structure, and the convergent and discriminant validity of the resultant scales. The findings support four subscales: two related to attitudes (i.e., Treatment Makes Sense and Treatment Fits Needs), one related to perceived behavioral control over participation (i.e., Participation Control), and one related to perceived family attitudes about CPT/PE participation (i.e., Subjective Norms). Scale validity was supported through significant associations with theoretically relevant constructs, including intentions to persist in CPT/PE, rs = .19-.38; treatment completion, rs = .21-.25; practical treatment barriers, rs = -.19 to -.24; and therapeutic alliance, rs = .39-.57.

Making sense of poor adherence in PTSD treatment from the perspectives of veterans and their therapists.

OBJECTIVE: Dropout rates from trauma-focused PTSD treatments (TFTs) in VA clinics are particularly high. We conducted in-depth qualitative interviews with 29 veterans and their therapists to better understand this phenomenon. METHOD: Participants were part of a multisite, mixed-methods study of TFT adherence in VA clinics. Veterans were eligible for interviews if they exhibited poor TFT adherence and screened positive for PTSD in follow-up surveys. Interviews were analyzed using qualitative dyadic analysis approaches. RESULTS: Therapists relied on stereotypes of poor adherence to understand veterans' experiences and were missing information critical to helping veterans succeed. Veterans misunderstood aspects of the therapy and struggled in ways they inadequately expressed to therapists. Therapist attempts at course corrections were poorly matched to veterans' needs. Many dyads reported difficulties in their therapeutic relationships. Veterans reported invalidating experiences that were not prominent in therapists' interviews. CONCLUSIONS: Future work is needed to test hypotheses generated and find effective ways to help veterans fully engage in TFTs. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Veterans with poor PTSD treatment adherence: Exploring their loved ones' experience of PTSD and understanding of PTSD treatment.

Trauma-focused psychotherapies such as cognitive processing therapy (CPT) and prolonged exposure (PE) are some of the most effective treatments available for posttraumatic stress disorder (PTSD). These treatments have been widely disseminated and promoted throughout the VA Health care System. However, adherence to and completion of these protocols among veterans is often poor, resulting in diminished impact. "Support persons" (SPs) such as relatives and close friends may provide a source of emotional or practical support in treatment, but little is known about how SPs are involved in or exposed to treatment principles and activities. The primary goal of the current research was to examine the experience of SPs of veterans who had poor adherence to treatment. We were interested in SPs' knowledge about the treatment, their level of involvement in treatment activities or sessions, and their potential interest in more participation or education. Qualitative analyses were used to examine data collected from interviews with 19 SPs of veterans who had an unsuccessful course of CPT or PE. Results indicated generally very low levels of knowledge and treatment participation. However, among most SPs there was substantial interest in the possibility of more treatment involvement, particularly in order to receive guidance from the clinician about how to respond to the veteran's symptoms. We suggest that it is possible and desirable to incorporate loved ones more formally into such protocols. (PsycInfo Database Record (c) 2021 APA, all rights reserved).
