About

Sexual minority stressors (e.g., sexual minority identity-based discrimination) contribute to greater risk for and severity of depression, anxiety, substance use disorders and suicide among sexual minority Veterans. However, no brief, scalable, one-on-one interventions targeting sexual minority stressor-related distress are available in Veterans Affairs (VA) for sexual minority Veterans. The proposed research will examine the feasibility, acceptability, and preliminary effectiveness of a brief, 3-session expressive writing intervention to target distress related to sexual minority stressor exposure among sexual minority Veterans. The results of this work will advance knowledge about a promising brief and easy to implement intervention focused on reducing depressive and anxiety symptoms among sexual minority Veterans. This proposal aligns with VA's and CSR&D's commitment to providing equitable services to sexual minority Veterans and the aim of reducing health disparities among underserved Veteran groups.

Full description

Sexual minority Veterans (e.g., gay, lesbian, bisexual) are one of the highest risk populations for psychiatric disorders due in part to the experience of discrimination and stigma-based stressors (sexual minority stressors). These stressors and the associated stress responses contribute to greater severity of depression and anxiety, which confer risk for negative health outcomes (hazardous substance use and suicide). However, very few interventions target distress related to sexual minority stressors, and even fewer have been tested in Veteran Health Administration (VHA). Brief, easy to implement interventions that target distress related to sexual minority stressors are needed to address the unique mental health concerns of this high risk community of Veterans. Expressive writing is a brief, well-developed paradigm that involves writing about thoughts and emotions related to a stressful experience for at least 15 minutes, 3-5 times based on a structured writing prompt. Over 30 years of research supports expressive writing's effectiveness in reducing stress, depression, and anxiety related to a stressor. Expressive writing on a minority stressor (EWMS) has been shown to reduce depression and anxiety among sexual minority non-Veterans but has never been tested among sexual minority Veterans. The aim of the proposed study is to examine the feasibility, acceptability, and preliminary effectiveness of EWMS, a promising intervention for sexual minority Veterans. Based on consultation with experts in expressive writing and sexual minority Veteran health, EWMS will be adapted for sexual minority Veterans and a VHA clinic setting. EWMS will be implemented as a 3 session, one-on-one intervention with a therapist. The proposed EWMS protocol will be iteratively refined in a case series (n = 10), and then tested in a pilot randomized control trial (RCT; n = 54) comparing EWMS to a neutral writing control condition. Aims of the pilot RCT are: 1) demonstrate feasibility and acceptability of study procedures and EWMS using quantitative and qualitative data; and 2) examine the preliminary effectiveness of EWMS relative to control in reducing depressive and anxiety symptom severity. The proposed research aims are in direct alignment with the applicant's short term and long term training goals. The proposed research and complimentary mentorship and training plans will enable the applicant to: 1) gain expertise in intervention adaptation and clinical trial research; 2) gain expertise in sexual minority health; 3) develop aptitude in implementation theory and processes to inform future implementation of the proposed intervention and other interventions; and 4) achieve career independence. The results of the pilot RCT along with the training and mentorship of this project will inform a Merit award submission comparing EWMS with an active control in a hybrid I implementation-effectiveness trial to test the efficacy of the intervention while collecting information on barriers and facilitators to implementation of the intervention. This proposed research, training, and mentorship plan will provide the applicant with the necessary skills and experience to transition into an independent clinical researcher in VA focused on the development, enhancement, and implementation of interventions for minority related stress among sexual minority Veterans. The research and training will take place at the National Center for Posttraumatic Stress Disorder at the VA Boston Healthcare System under the supportive, collaborative, and accomplished mentorship team, including Drs. Brian Marx (primary mentor), Katherine Iverson (co-mentor), and Nicholas Livingston (co-mentor). These mentors have unique, yet complimentary, areas of expertise and have an established and successful history working together and with the applicant. The research, mentorship, and training proposed will facilitate the applicant's transition into a successful and productive independent VA investigator conducting research that directly aligns with VA's priority to provide equitable, patient-centered services to Veterans.

Inclusion criteria

Participants will be Veterans who:

• identify as a sexual minority (i.e., identify as gay, lesbian, bisexual, pansexual, queer, or another identity other than heterosexual)
• endorse clinically significant depressive or anxiety symptoms (score above 10 on the PHQ-9 or GAD-7)
• report a history of sexuality-based minority stressor exposure that is contributing to distress on phone screening
• be stable on psychotropic medication for at least 4 weeks if on a psychotropic medication

Exclusion criteria

The exclusion criteria for Veterans in this study are:

• clear and current suicidal plan and/or intent (assessed via the Columbia Suicide Severity Rating Scale)
• current presentation of unstable mania and/or psychosis (assessed via the Structured Interview for DSM-5)
• current substance use disorder, severe (assessed via the Structured Interview for DSM-5)
• significant cognitive impairment, including evidence of moderate or severe traumatic brain injury, determined by an inability to comprehend baseline screening questionnaires

Expressive Writing on Minority Stressors

Experimental group

Description:

The EWMS protocol will consist of 3 sessions delivered by a therapist (either in-person or remotely via telehealth platform) to sexual minority Veterans. The intervention will begin with an overview of the intervention, brief psychoeducation about expressive writing, and a review of the potential benefits of expressive writing. The initial session will also consist of psychoeducation on sexual minority stressors and common reactions to these stressors (i.e., universal stress reactions and minority-identity specific reactions) and how this relates to psychological outcomes, such as depression and anxiety, and high-risk behaviors, such as substance use and suicidal ideation. The initial session will be 60 minutes (introduction, psychoeducation, and first writing exercise) and the following two sessions (feedback, writing exercises, and check-ins) will take approximately 40 minutes.

Treatment:

Behavioral: Expressive Writing on Minority Stressors

Neutral Writing

Placebo Comparator group

Description:

To be comparable to EWMS, the control intervention will also be a 3-session individual intervention involving engaging in a writing exercise per session. For the control writing exercises, participants will be asked to write for 30 minutes about their daily activities since waking up that day based on Pennebaker's standard writing paradigm (Pennebaker \& Beall, 1987). Individuals in the control condition will also be given information about the purpose of the writing exercises to be comparable to the psychoeducation information provided in EWMS. Similar to EWMS, the clinician will check in with the participant about the writing session, such as asking how the session went and how it felt to do the writing, following the 30 minutes of writing.

Treatment:

Behavioral: Neutral Writing
