Conditions: Posttraumatic Stress Disorder

Interventions: Behavioral: STAIR-PC Group
Behavioral: WebSTAIR Group

Registration Number: NCT04937504

Lead Sponsor: Boston Medical Center

Brief Summary: A majority of residents in low income communities have been exposed to a potentially traumatic event, and up to half (30-50%) of trauma-exposed residents in safety net clinical settings meet criteria for posttraumatic stress disorder (PTSD). Despite this, only 13% receive treatment. Poor access to PTSD treatment is due to a shortage of mental health specialists.

This study aims to evaluate the implementation and effectiveness of a brief, cognitive-behavioral intervention for posttraumatic stress disorder (PTSD)-Skills Training in Affective and Interpersonal Regulation (STAIR)- that will be offered in Boston Medical Center (BMC)'s primary care clinics as the new standard of care following integrated behavioral healthcare (IBH) therapist training. In response to clinician capacity concerns and the impact of the COVID-19 pandemic, we will be offering the intervention in both clinician-administered and self-paced, web-administered formats. The evidence base suggests that STAIR, delivered both synchronously (in-person/telehealth STAIR) and asynchronously (webSTAIR), is associated with significant improvements in PTSD and depression symptoms.

Detailed Description: Participants who enroll in the study will be randomized to either in-person/telehealth STAIR or webSTAIR. Those who do not enroll in the study will still be able to receive STAIR in person or via telehealth as part of usual care.

Participant data will be for 9 months. Treatment plans will continue to be determined by usual care providers, the study has no involvement in any decisions regarding care. This means that a participant's IBH therapist can continue the therapy, offer a different treatment option, or refer to other services at any time in the study and after the study is completed. At any time, patients can also choose to change their treatment plans, for example from webSTAIR to in-person/telehealth STAIR, or to another treatment option in the clinic. Access to webSTAIR will be discontinued at 9 months.

The investigators hypothesize that offering a low intensity treatment for PTSD through primary care will improve access to and engagement in care for PTSD among BMC's patient population. The feasibility of two modes of treatment delivery will be compared, while gathering further evidence of the effectiveness of the intervention in our local setting. It is also hypothesized that both formats will be effective in reducing mental health symptoms, while webSTAIR may have some advantages in regard to uptake and long-term sustainability in usual care.

Exclusion Criteria

Currently receiving cognitive behavioral therapy for PTSD elsewhere e.g., cognitive processing theory (CPT), prolonged exposure (PE), eye movement desensitization and reprocessing (EMDR).

Arm && Interventions

Group	Intervention	Description
STAIR-PC Group	STAIR-PC Group	Participants in the Skills Training in Affective and Interpersonal Regulation for Primary Care (STAIR-PC) group will complete five (30 minute each) therapist-led sessions in-person or via Telehealth for up to 12 weeks.
WebSTAIR Group	WebSTAIR Group	Participants in the WebSTAIR group will complete 10 self-guided, web-based modules for up to 12 weeks.

Primary Outcome Measures

Name	Time	Method
Posttraumatic Stress Disorder Symptoms Measured by PTSD Checklist for DSM-5 (PCL-5)	Baseline, 15 weeks, and 9 months	The PTSD Checklist for DSM-5 (PCL-5) is a 20-item self-report measure that assesses the 20 DSM-5 symptoms. The PCL-5 scale ranges from Not At All (0) to Extremely (4) so the PTSD checklist total scores can range from 0 to 80, where higher scores indicate higher severity of PTSD symptoms.
Feasibility Based on Retention	15 weeks	The number of participants who completed at least 90 minutes of an intervention by 15 weeks
Acceptability Measured by Client Satisfaction Questionnaire (CSQ-8)	15 weeks, 9 months	The Client Satisfaction Questionnaire (CSQ-8) is an 8-item survey to measure and assess consumer satisfaction with health and human services. Response options differ for each item, the scale ranges from very negative response (1) to a very positive response (4), and the total range for the CSQ-8 can be from 1 to 32 with higher scores indicating higher satisfaction.

Secondary Outcome Measures

Name	Time	Method
General Mental Health Functioning Measured by the Brief Symptom Inventory (BSI-18)	Baseline, 15 weeks, 9 months	The Brief Symptom Inventory (BSI-18) is an 18-item self-report measure to assess psychological problems. The responses for each item ranges from Not At All (0) to Extremely (4), so the toal scores can range from 0 to 72. Higher total scores indicate higher severity of psychological distress.
Emotional Regulation Measured by the Difficulties in Emotion Regulation Scale (DERS)	Baseline, 15 weeks, 9 months	The Difficulties in Emotion Regulation Scale (DERS) is a 36-item self-report measure of emotion regulation difficulties. Individual item responses range from Almost never (1) to Almost always (5), creating a potential total score range for the DERS of 36 to 180. Higher total scores indicate higher symptom severity.
Trauma Symptoms as Assessed by the Trauma Symptoms of Discrimination Scale (TSDS) of Discrimination Scale,	Baseline, 15 weeks, 9 months	The TSDS assesses discriminatory distress and anxiety-related trauma symptoms. It includes 21 items, each of which is rated on a 4-point scale ranging from 1 (Never) to 4 (Often). The total score of the TSDS is calculated by adding up the scores from all items and can range from 21 to 84. HIgher scores are asociated with more trauma.
Social Functioning Measured by the Interpersonal Support Evaluation List - 12-item Version (ISEL-12)	Baseline, 15 weeks, 9 months	The Interpersonal Support Evaluation List - 12-item version (ISEL-12) is a 12-item self-report measure to assess perceptions of social supports. Each item response ranges from Definitely false (1) to Definitely true (4), creating a total score range of 12 to 48. Higher total scores indicate greater social supports.
