Reducing Dropout and Improving Outcomes From PTSD Therapy: When to Switch Therapies or Stay the Course

BEHAVIORAL

CPT Skills

CPT trainings recommend that if an individual is experiencing challenges with the CPT protocol (e.g., ambivalence about continuing treatment or struggling with completing homework), the provider can apply the skills of CPT to that particular problem. Those skills include problem solving and cognitive restructuring to identify and alter maladaptive underlying beliefs. The purpose of this work is to address the individual's underlying problem or problematic beliefs to improve the individual's attitudes about CPT and/or improve the individual's compliance with treatment activities. The therapist's end-goal is to keep the individual moving forward in the CPT protocol.

BEHAVIORAL

Cognitive Processing Therapy

CPT is a 12-session, cognitive-behavioral treatment for PTSD that focuses on challenging and modifying maladaptive beliefs related to prior trauma. The goal is to build a new understanding of prior trauma in order to limit the negative influence trauma and it's reminders have on individuals' daily lives. The treatment involves education about PTSD and skill building to identify and challenge maladaptive, trauma-related thinking through Socratic questioning and worksheets that teach individuals to challenge this thinking themselves. Later sessions focus on specific themes that are difficult for individuals with PTSD and can keep individuals "stuck" in their symptoms. Themes include safety, trust, control, self-esteem, and intimacy. Although the skills utilized in CPT may be used to respond to challenges individuals have with participating in CPT, the effectiveness of these strategies has not been explicitly tested.

BEHAVIORAL

Present Centered Therapy

PCT was developed as a comparator for "active" TFT, so protocol length typically matches the comparator. PCT focuses on "current life problems as manifestations of PTSD" in weekly 60-minute sessions. It includes psychoeducation and normalization of responses to trauma, problem solving related to life difficulties and stress, and emotional support and validation. Its hypothesized mechanisms are increased interpersonal connection and mastery in managing life stressors. Therapist skills include validation, support, and reflective listening. The first 2 sessions provide an overview and rationale for PCT. Subsequent sessions focus on topics participants choose and are less structured. Participants use a daily diary to record any concerning problems or issues they experience during the week. These diaries are used to select session topics.

BEHAVIORAL

Shared Decision Making

Shared decision making (SDM) is widely considered the best model for achieving patient-provider agreement on treatment plans and an ethical imperative for decision making. SDM is a communicative process in which patients and their provider personalize treatment approaches to the individual, their situation, and the problems that they are experiencing. Providers and patients engage in a shared deliberation of meaningful treatment alternatives, including pros and cons, how choices align or misalign with values, and patients' abilities to complete the plans under consideration.

BEHAVIORAL

Measurement Based Care

Investigators will compare methods of identifying individuals experiencing challenges in CPT. Investigators will use self-report measures administered each week during treatment to identify individuals who may be struggling in during CPT and compare two approaches to cut scores on these measures to classify individuals as "in need of intervention." Investigators will also use behavioral indices to determine if veterans are in need of intervention, including homework compliance and session attendance. One approach will liberally classify many individuals as "in need of intervention" (Catchall), while the other will take a more targeted approach (Targeted).

PTSD severity (via structured clinical interview)

Time frame: Baseline, through six-months after treatment completion. Treatment completion takes an average of 4 months.

Measured using the Clinician-Administered PTSD Scale for the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (CAPS-5). This standardized interview is conducted by an evaluator blinded to study condition, via telehealth.

What is a clinical trial?

A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.

Is it safe to participate?

Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.

Will I be compensated?

Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.

Will I receive a placebo instead of treatment?

When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.

Can I leave a trial if I change my mind?

Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.

How long does a clinical trial last?

Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
