Clinical Trial Summary

The U.S. Deaf community - a group of more than 500,000 Americans who communicate using American Sign Language (ASL) - experiences nearly triple the rate of lifetime problem drinking and twice the rate of trauma exposure compared to the general population. Although there are several treatments for alcohol use disorder (AUD) and posttraumatic stress disorder (PTSD) in hearing populations, none have been developed for or tested with Deaf clients. To address these barriers, the study team developed Signs of Safety, a Deaf-accessible therapy toolkit for treating AUD and PTSD. Their aims are to conduct a nationwide, virtual clinical trial to compare (1) Signs of Safety with (2) treatment as usual and (3) a no treatment control, to collect data on clinical outcomes, and to explore potential mediators and moderators of outcome.

Description:

In partnership with Deaf-owned agency National Deaf Therapy, the study team will conduct the first-ever full-scale psychotherapy trial conducted in the Deaf community - "Evaluating Signs of Safety: A Deaf-Accessible Therapy Toolkit for AUD and Trauma." The U.S. Deaf community - more than 500,000 Americans who communicate using American Sign Language (ASL) - experiences nearly triple the rate of lifetime problem drinking compared to the general population (33.0% vs. 12.3%) and twice the rate of trauma exposure. Among Deaf people in treatment for alcohol use disorder (AUD), 74% report lifetime physical, emotional, or sexual abuse and 44% report past-year abuse. Comorbid AUD/PTSD impairs multiple domains of functioning, especially for Deaf individuals, who show poorer functional outcomes than hearing individuals in socialization, employment, and physical health. Hearing individuals have access to several validated treatments for comorbid AUD/PTSD; yet there are no evidence-based treatments to treat any behavioral health condition with Deaf clients. Available treatments fail to meet Deaf clients' unique language access needs. Deaf people's median English literacy level falls at the fourth grade and health-related vocabulary among Deaf sign language users parallels non-English-speaking U.S. immigrants. Available treatment resources, therefore, require plain text revisions, filmed ASL translations, or education through storytelling to better match Deaf clients' language needs. Leveraging extensive community engagement to address these barriers, the Principal Investigator's team of Deaf and hearing researchers, clinicians, filmmakers, actors, artists, and Deaf people with AUD/PTSD developed and pilot tested Signs of Safety, a Deaf-accessible toolkit to be used with the Seeking Safety treatment protocol. Seeking Safety is a manualized, non-exposure-based, cognitive behavioral therapy for trauma and addiction. Among evidence-based treatments for AUD/PTSD, Seeking Safety is the optimal choice for Deaf clients - its focus on psychoeducation and simple coping skills is an ideal match for Deaf people's language and literacy disparities, which prohibit the use of narrative, verbal problem-solving, and cognitive processing strategies that other AUD/PTSD therapies require. Yet, Seeking Safety's client materials rely on written English and are, therefore, not well understood by Deaf clients. As such, the Signs of Safety toolkit provides a supplemental therapist guide and population-specific client materials (e.g., visual handouts, filmed ASL teaching stories). Preliminary data from the Signs of Safety single-arm pilot and randomized feasibility pilot showed reductions in alcohol use frequency and PTSD severity from baseline to follow-up on the Reliable Change Index. The delivery of the experimental intervention was deemed feasible by study therapists and was well-received by participants, especially when moved to a virtual platform. In response to the COVID-19 pandemic, the study team overhauled in-person study methods to implement a virtual clinical trial - an acceleration of the inevitable development needed to scale Signs of Safety to a national level. This adaptation also established a crucial collaboration with National Deaf Therapy (NDT), by far the nation's largest provider of Deaf mental health services, currently serving clients across 21 states. This collaboration, paired with comprehensive feasibility data the study team collected by testing a variety of virtual methods, serves as the foundation of the study team's proposed aims. The study team will conduct a nationwide, full-scale, virtual clinical trial of Signs of Safety. Leveraging the existing infrastructure and robust referral network of NDT, the study team will enroll 144 Deaf adults with past-month PTSD and problem drinking. Primary clinical outcomes at immediate post-treatment and post-treatment follow-up are past 30-day alcohol use frequency/quantity (Alcohol Timeline Followback) and past 30-day PTSD severity (PTSD Checklist for DSM-5). Assessment will occur at baseline, mid-treatment, immediate post-treatment, three-month post-treatment follow-up, and six-month post-treatment follow-up. Participants residing in states served by NDT (n = 96) will be randomized to receive either (1) a 12-session protocol of Seeking Safety + Signs of Safety, or (2) 12 sessions of therapy as usual (TAU; general, open-ended, non-manualized supportive counseling provided by an NDT therapist). The study team will enroll an additional 48 Deaf adults into a contemporaneous no-treatment control arm. These individuals will be recruited from the existing NDT waitlist, comprised of Deaf individuals residing in the states not yet served by NDT but voluntarily awaiting NDT services. Additionally, the study team will analyze potential moderators and mediators that lead to positive outcome. Identified from the literatures on Seeking Safety, alcohol treatment research, and Deaf mental health research, mechanisms of change are coping self-efficacy, self-compassion, motivation for treatment, and access to health information. They study team's proposed aims build upon eight years of empirical work, moving the program of research from Stage IB (two-arm feasibility and pilot testing) to Stage II/III (real world efficacy). This clinical trial will potentially validate the first-ever evidence-based therapy for Deaf people, as well as provide future behavioral health researchers with a vital roadmap for conducting community-engaged clinical trials with Deaf people.

Eligibility

Inclusion Criteria:

• Self-identification as Deaf or hard-of-hearing
• Proficiency in American Sign Language (ASL)
• Age 18 years or older
• Access to videoconferencing technology for informed consent and, if applicable, study therapy sessions
• Access to online survey technology for study assessments
• "Problematic alcohol consumption, drinking behaviors, and alcohol-related problems" on the AUD Identification Test (AUDIT), a 10-item screening measure developed by the World Health Organization that demonstrates good sensitivity and specificity in many populations (past-month referent time period; score = 8 for men or = 6 for women)
• "Subthreshold or full PTSD," on the PTSD Checklist for DSM-5 (PCL-5), a 20-item measure of PTSD symptoms reliably used to monitor symptom change (past-month referent time period; "subthreshold" = meets at least two DSM-5 diagnostic categories (B, C, D, and/or E) at moderate or high severity)

Exclusion Criteria:

• Participation in concurrent formal psychotherapy (Note: Participants in all study conditions will be asked to refrain from concurrent formal psychotherapy. Participants who engage in formal psychotherapy outside of the research will be removed from the study at the point of treatment initiation. Outside treatment engagement will be queried at each assessment timepoint. If endorsed, the participant will be removed from the study at that timepoint, but data collected prior to treatment initiation will remain in the dataset. Aligning with the Seeking Safety model, Alcoholics Anonymous/Narcotics Anonymous/Dual Recovery Anonymous attendance will be encouraged; attendance will be tracked as a potential outcome mediator.)
• Members of the following special populations: Adults unable to consent; Individuals younger than 18 years; Prisoners; Pregnant women (Note: We will not knowingly include pregnant women as participants; however, we will not assess participants' pregnancy status.)

Intervention

Behavioral:
• Seeking Safety + Signs of Safety toolkit
Signs of Safety is a Deaf-accessible toolkit to be used with the Seeking Safety treatment protocol. Seeking Safety is a manualized, non-exposure-based, cognitive behavioral therapy for trauma and addiction.
• Treatment as usual
NDT therapists come from a wide variety of training backgrounds, but each works with their clients to build on their existing strengths and provide support as clients develop new strategies and behaviors for overcoming adversity.
