The efficacy of psychological interventions for posttraumatic stress disorder (PTSD) is likely limited by the difficulty participants have learning and remembering important therapy content. Accordingly, the present study will examine the utility of integrating a Memory Support (MS) intervention into Cognitive Processing Therapy (CPT), an empirically supported and widely disseminated treatment for PTSD. MS was designed to integrate techniques aimed at facilitating encoding, consolidation, and retrieval of new learning into existing treatments, and has been shown to improve outcomes when integrated into cognitive therapy for depression. A pilot randomized controlled trial (n=52) comparing CPT with Memory Support (CPT+MS) to CPT-alone will be conducted. Study participants will be adults diagnosed with PTSD.
The primary aim of the trial will be to determine if CPT+MS will lead to greater memory and learning of therapy content relative to CPT-alone, and to establish the acceptability and feasibility of integrating MS into CPT. Secondary aims include a preliminary examination of treatment efficacy, as indicated by the magnitude of changes in PTSD symptoms between conditions, and target validation, as indicated by associations between memory and learning of therapy content and treatment response. Exploratory analyses will examine several indicators of baseline memory-related cognitive functioning as predictors of memory and learning of therapy content, providing preliminary data to inform future research on personalized application of MS. Results of the trial will advance scientific knowledge about methods for optimizing memory and learning as a mechanism for improving PTSD treatment outcomes.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Cognitive Processing Therapy + Memory Support (CPT + MS) | Experimental | CPT + MS will involve the same treatment strategies as CPT while incorporating deliberate and frequent use of memory and learning support strategies. MS strategies are designed to enhance the memory of specific treatment points, defined as any insight, skill or strategy determined to be important for the patient to remember and/or implement. MS is not designed to enhance memory functioning generally, but rather improve the encoding, consolidation and retrieval of specific components of therapeutic learning. |
|
| Cognitive Processing Therapy (CPT) | Active Comparator | CPT is a manualized, trauma-focused therapy for PTSD. Treatment consists of psychoeducation on the cognitive model of PTSD, identification of trauma-related stuck points (i.e. dysfunctional beliefs), and cognitive challenging techniques to help participants identify more realistic and adaptive ways of viewing their trauma, themselves, and the world. |

| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| CPT | Behavioral | CPT will be delivered over the course of 12 one-hour weekly sessions (maximum of 18 weeks to complete treatment). Participants will have the option of receiving CPT in-person or via videoconferencing. |
| Measure | Description | Time Frame |
|---|---|---|
| Mid-treatment Memory of therapy content assessed by the Therapy Recall Task | The Therapy Recall Task involves participants writing down as many distinct "treatment points" as they can in a 10-minute period. Treatment points are defined as insights, skills, or strategies they think are important to remember or implement as part of their therapy. Responses are scored based on the number of distinct treatment points described. | 6 weeks |
| Post-treatment Memory of therapy content assessed by the Therapy Recall Task | The Therapy Recall Task involves participants writing down as many distinct "treatment points" as they can in a 10-minute period. Treatment points are defined as insights, skills, or strategies they think are important to remember or implement as part of their therapy. Responses are scored based on the number of distinct treatment points described. | 12 weeks |
| Follow-up Memory of therapy content assessed by the Therapy Recall Task | The Therapy Recall Task involves participants writing down as many distinct "treatment points" as they can in a 10-minute period.

Responses are scored based on the number of distinct treatment points described. | 6 months |
| Feasibility assessed by mean CPT Adherence | CPT adherence is defined as the portion of CPT protocol elements completed across therapy sessions, rated from 0-100%. This will be assessed via observer ratings of a random selection of 25% of tapes/session recordings from each treatment condition using the CPT Therapist Adherence and Competence Protocol - Revised. Completion of ≥ 90% mean adherence to protocol elements indicates high CPT adherence, and would be an indicator of feasibility of CPT+MS. | 12 weeks |
| Feasibility assessed by mean CPT Competence |
| Measure | Description | Time Frame |
|---|---|---|
| Mid-treatment Memory of Therapy Content assessed by the Treatment Thoughts and Application Task | The Treatment Thoughts and Application Task assesses the number of treatment points participants thought about and applied in the previous 24 hours.

| Measure | Description | Time Frame |
|---|---|---|
| Post-treatment Change in cognitive complaints assessed by the Cognitive Self-Report Questionnaire - Cognitive subscale (CSRQ-C) | The CSRQ-C is a 10-item self-report questionnaire assessing various cognitive complaints, including memory difficulties. Scores range from 10-50, with higher scores indicating greater cognitive complaints. | Baseline, 12 weeks |

| MS | Behavioral | The MS protocol consists of eight strategies: categorization, evaluation, application, cue-based reminders, practice remembering, attention recruitment, praising recall, and repetitions. |
|
CPT competence will be assessed via observer ratings of a random selection of 25% of tapes/session recordings from each treatment condition of the competence with which CPT protocol elements are delivered, rated from 1 (poor) to 7 (excellent). This will be assessed via observer ratings of a random selection of session recordings using the CPT Therapist Adherence and Competence Protocol - Revised. A mean skill rating of "good" or higher (≥5 on a 7-point Likert scale) on protocol elements indicates high CPT competence, and would be an indicator of feasibility of CPT+MS. |

| Feasibility assessed by the Memory Support Rating Scale (MSRS) | The Memory Support Rating Scale (MSRS) is an an observer-rated scale used to measure the type and frequency of Memory Support strategies used.
