Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to evaluate an online PTSD intervention that was adapted for women Veterans, called DElivery of Self TRaining and Education for Stressful Situations-Women Veterans version (DESTRESS-WV). The intervention consists of structured online sessions as well as weekly brief phone calls for additional support with a study coach. Women Veterans with PTSD who are eligible will be randomized to receive either DESTRESS-WV or phone monitoring only for 8 weeks. Participants will be assessed immediately post-treatment as well as at 12 and 24 weeks post-treatment. Investigators hypothesize that participants randomly assigned to DESTRESS-WV will have a greater decrease in severity of PTSD symptoms compared to those randomly assigned to phone monitoring only.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The RCT will target women Veterans with PTSD to compare the adapted, web-based intervention to phone monitoring only. Participants will include women Veterans with PTSD who are not actively receiving PTSD treatment. They will be interviewed via phone for an initial phone screening and eligibility interview and will complete additional online surveys at baseline, post-treatment, and 12-, and 24-week follow-up.

Recruitment. Women Veterans who live in Pacific or Mountain Time Zones with an ICD code for PTSD or a positive VA mandated PTSD screen, with no mental health stop-code in the last 2 months, and who are not on the high risk list for imminent danger to self or others, will be identified using a VINCI data pull. Individuals with these criteria will be mailed up to two invitation letters and a brochure describing the study inviting them to contact the study office. If women do not contact the study office to opt out of the study, the investigators may call them to follow-up. The investigators aim to obtain a sample of 100 individuals that meet study inclusion/exclusion criteria after providing informed consent. Because the investigators aim to recruit participants for approximately 24 months, the investigators will aim to enroll and randomize 4-5 participants per month.

Procedure. The RCT will involve four assessment phases: initial phone screen to ascertain interest and basic inclusion/exclusion eligibility, assessment of diagnostic eligibility in a full eligibility interview, baseline survey of outcomes of interest prior to initiating treatment, and three follow-up surveys of outcomes of interest at post-treatment and 12- and 24-weeks post-treatment. Patients will be randomized to condition following completion of the baseline online survey. The eligibility interview and study coach phone calls will be audio-recorded to ensure adherence to the study protocol.

Phone screen (10-15 minutes). When interested women Veterans contact the study office, study personnel will provide an overview of the study and, for those still interested, conduct an initial pre-consent screening. The purpose of the pre-consent eligibility screening is to quickly determine which candidates are most likely to qualify, thus eliminating the need to conduct consent and full eligibility interviews for those who are unlikely to meet study criteria. If patients are found to be eligible following the pre-consent eligibility screening, study staff will review the consent process, including willingness to be audio-taped during assessments and study coach calls, answer any questions, and mail the consent form to the participant to obtain written consent, along with a demographic form and Life Events Checklist. The full eligibility interview will be scheduled at this time but will only be conducted if and when the signed, written informed consent, HIPAA form, demographic form, and Life Events Checklist have been received in the study office.

Eligibility interview (95-150 minutes). Study personnel will call the potential study participant to conduct the eligibility interview over the phone after written, informed consent has been received in the study office. The interview will assess current PTSD as addressed by the CAPS interview as well as various exclusion criteria. During the course of the interview, if study personnel are concerned about the fit of the study for the potential participant, they will discuss with the PI. Potential participants who are of concern and may show a high risk profile (e.g., multiple past suicide attempts, inpatient hospitalizations, lifetime psychotic disorders) or prominent disorganization while on the phone will be discussed by the PI and co-investigator Dr. Simpson for possible exclusion.

Respondents who do not meet eligibility criteria will be offered a resource list, referred for treatment, and/or be further assessed for suicidality as appropriate. For those who are eligible, contact information (e.g., address, telephone number) and contact information for at least one friend or family member who typically would know the whereabouts of the participant should study staff have difficulty making contact will be recorded. Eligible patients will be invited to complete a baseline online survey.

Baseline and follow-up online surveys (60-90 minutes). The baseline and follow-up surveys (at post-treatment and 12- and 24-week follow-ups) consist of an online survey. Each online survey takes 60-90 minutes to complete. Participants will be compensated for the baseline survey, for each of the follow-up surveys, and a bonus for completing all surveys. If the interval between the eligibility interview and baseline survey is longer than four weeks, we will require re-administration of CAPS via telephone to ensure PTSD status. Participants will be given one-week and one-day reminders to complete the survey. Following completion of the baseline survey, participants will be randomly assigned to one of the conditions.

Randomization scheme. Fifty participants will be randomized to the adapted, web-based intervention and 50 to phone monitoring only. Participants will be randomized following their completion of the baseline survey. Stratification of randomization by rural status will be done to facilitate exploratory analyses of the impact of this variable on trial outcomes. Following randomization, the study coach will arrange an initial telephone session with each participant.

Study conditions. The treatment phase for both study conditions will last 8 weeks; however, participants will have up to 12 weeks to complete the intervention and complete study coach calls, if needed.

Phone monitoring condition. Participants randomized to the phone monitoring condition will receive calls from a study coach once a week for 8 weeks for approximately 10-15 minutes. The coach will assess their PTSD symptoms and safety.

DESTRESS-WV. Those randomly assigned to the web-based intervention will also receive calls from a study coach once a week for 8 weeks to assess PTSD symptoms and safety; the coach will also review the participant's progress with the DESTRESS-WV website. Participants will be instructed to log-on to the website twice per week, with each session taking approximately 30-60 minutes. The web-based intervention consists of 16 sessions involving structured, cognitive-behavioral components, including cognitive restructuring and in-vivo and imaginal exposure. Participants will be reminded of the study office phone number as well as the Veterans Crisis Line phone number at every logon.

Intervention Type BEHAVIORAL

This is an online intervention for PTSD tailored for women Veterans. The intervention is based on cognitive behavioral therapy (CBT). The goal of CBT is to help people recognize and address their thoughts and behaviors in positive ways with the aim of improving their ability to function as well as possible in their lives. Participants will be asked to log on to the website twice per week for about 30-60 minutes each time. Homework assignments will include stress management skills that participants will be asked to practice and apply. A study coach will call each participant once a week for 8 weeks for about 15 minutes to review their progress with the program.

She will encourage participants to use the time on the call to discuss any current life issues or problems that they would like. Active listening and rephrasing will be used, while teaching cognitive-behavioral strategies will be avoided.
