Brief Summary
Less than 20% of people with PTSD receive any treatment. This study extends a program of research by the investigator focused on developing adaptive (stepped) interventions for PTSD. The adaptive intervention sequences a digital mental health intervention (DMHI) and brief trauma- and skills-focused treatments for PTSD. The selected treatments are brief and scalable and less burdensome to systems of care. These treatments are: web-administered Skills Training in Affective and Interpersonal Regulation (webSTAIR), Brief STAIR, and Written Exposure Therapy (WET).

Outcome Measures
Primary Outcomes (3)
PTSD symptom severity
This outcome will be assessed by the PTSD Checklist for the DSM-5 (PCL-5), a 20-item self-report measure that evaluates the degree to which individuals have been bothered by PTSD symptoms in the past month tied to their most distressing event. Total scores ranging from 0 to 80, and a score of 31-33 or higher suggests probable PTSD and potential benefit from treatment.
baseline, 4 weeks, 8 weeks, 18 weeks, 30 weeks
Treatment retention
as the proportion (%) of participant who complete 60% of interventions in the treatment windows.
4 weeks, 8 weeks, 18 weeks
Treatment acceptability
This outcome will be assessed with the Client Satisfaction Questionnaire 8 \[CSQ-8\], a 8-item instruction where scores are summed across items once. Items 2, 4, 5, and 8 are reverse scored. Total scores range from 8 to 32, with the higher number indicating greater satisfaction.

Interventions
Brief STAIR is a brief, low intensity, therapy that utilizes psychoeducation, coping skills training, and does not include recounting of the trauma memory, making it highly tolerable. It will be delivered by mental health clinicians in five to six 30-minute individual sessions.
WebSTAIR consists of 10 online modules that provide psychoeducation on trauma and emotions and teach skills to improve coping with emotions and strengthen interpersonal relationships. Modules are completed at the participants' own pace and utilize interactive exercises, and audio and video components to aid in delivery.
WebSTAIR with up to five 30-min coaching sessions with a CHW will focus on guiding participants through the program, discussing exercises that are valuable or problematic, and reviewing module content.
WET is a brief, high intensity, exposure-based treatment delivered by mental health clinicians consisting of six 30-minute individual sessions that cover treatment rationale, psychoeducation about PTSD, and directing participants to write in session about their traumatic experience using scripted instructions.
