Adaptive Decision-making And Personalized Treatment for PTSD (ADAPT-PTSD)

Not Applicable

Recruiting

• Conditions: Posttraumatic Stress Disorder; PTSD

• Registration Number: NCT07176273
• Lead Sponsor: The University of Texas Health Science Center at San Antonio

Brief Summary

By doing this research project, the investigators hope to learn which strategies work best to help veterans who are not benefiting from their first PTSD treatment or not completing between-session homework assignments regularly that might improve treatment response. The investigators also want to learn how best to match the right type and amount of treatment to each individual veteran. By conducting this research project, they hope to:

* See if trying a different treatment strategy for veterans not responding to their first PTSD treatment would be more helpful

* See if sending text message prompts between sessions encourages more completion of between-session homework

Detailed Description

This study is designed to assist the investigators in answering the clinical question of how to address non-response to first line PTSD treatments. Utilizing an innovative Hybrid Experimental Design (HED), the proposed study involves multiple, sequential randomizations to both therapist-delivered and digital interventions operating on short and long timescales to determine the optimal combination and sequencing of evidence-based interventions to maximize response. This will result in actionable data and, consistent with a personalized medicine approach, an implementable, adaptive treatment regimen that optimizes clinical resource allocation. By recruiting and providing treatment in routine care settings serving veterans with PTSD, the study design maximizes generalizability, relevance to the VA mission, and implementation potential.

Primary Outcome Measures

Name	Time	Method
Posttraumatic Stress Disorder Checklist (PCL-5)	10 weeks, 20 weeks and 9 months	The PCL-5 is a psychometrically valid measure and commonly used assessment of PTSD symptoms. A total score is calculated by adding up the ratings for each of the 20 items, which range from 0 to 4 (0=Not at all, 4=Extremely). Higher scores reflect more severe symptoms. A score below 31 generally suggests a sub-clinical range, while scores of 31 or above fall within the clinical range, indicating probable PTSD.

Secondary Outcome Measures

Name	Time	Method
Columbia Suicide Severity Rating Scale (C-SSRS)	Baseline, 10-weeks, 20-weeks, 9-months	The C-SSRS is a standardized measure used to assess suicide risk, primarily through the presence and severity of suicidal ideation and behavior. The screener version of the C-SSRS consists of 2-6 "Yes" or "No" questions. Responses to questions 1 and 2 determine if questions 3, 4, and 5 are asked. A 'Yes' answer to question 2 prompts questions 3, 4, 5, and 6. A 'No' answer to question 2 directs the responder to question 6. Affirmative ("Yes") responses are summed, with each 'Yes' counting as 1 point. This summation provides a score on a scale of 0-6 indicating suicide risk level.; 0 = No risk reported (all "No" responses).; 1 - 2 = Low risk. 3 - 6 = Moderate to high risk. A "Yes" response to question 3 or 6a indicates moderate risk (potential plan or lifetime engagement in preparatory behavior). A "Yes" response to question 4, 5, or 6b indicates high risk (active plan, possible intent, or recent preparatory behaviors).
Patient Health Questionnaire-9 (PHQ-9)	Baseline, 10-weeks, 20-weeks, 9-months	The PHQ-9 score indicates the severity of depressive symptoms. There are 9 items with scores ranging from 0-3 for each. Total scores range from 0 to 27, with higher scores indicating more severe symptoms. A score of 5-9 is considered mild, 10-14 is moderate, 15-19 is moderately severe, and 20-27 is severe. The PHQ-9 score is not a diagnosis, but rather a screening tool to assess depression severity and guide treatment decisions.
Quality of Life Enjoyment and Satisfaction Questionnaire-Short Form (Q-LES-Q-SF)	Baseline, 20-weeks, 9-months	The Q-LES-Q-SF contains 16 questions scored on a 5-point Likert scale with values from 1 ("Very Poor") to 5 ("Very Good"). A total score is calculated by summing the first 14 item responses and ranges from 14 to 70; higher scores are associated with greater life satisfaction and enjoyment. The total score is expressed as a percentage based on the maximum total score of the items completed (1-100). The normal range that represents community sample scores is 70-100, and thus scores below 70 are clinically significant. Note, the last two items (items 15 and 16) ask about medication and overall contentment and are stand-alone items; they are not included in the total score.
Brief Inventory of Psychosocial Functioning (B-IPF)	Baseline, 10-weeks, 20-weeks, 9-months	The B-IPF is a 7-item self-report instrument that evaluates PTSD-related psychosocial functional impairment within the last 30 days across seven functional domains (romantic relationships, family relationships, work, friendships and socializing, parenting, education, and self-care). Items on the B-IPF are scored on a Likert scale from 0 (never) to 6 (always). The B-IPF was designed so that respondents complete only temporally relevant items that reflect a domain that they have participated in over the past 30 days (e.g., participants who were not enrolled in school within the past 30 days are instructed to skip the education item). The BIPF is scored by summing the scored items to create a total score, dividing the total score by the maximum possible score based on the number of items scored, and multiplying by 100. Thus, the B-IPF represents an overall index of functioning, with higher scores indicating greater functional impairment
