Evaluation of Momentary Affect Regulation - Safer Sex Intervention

The Policy \& Research Group (PRG) will be conducting a rigorous evaluation of an innovative intervention designed to reduce unplanned pregnancy and sexually transmitted infections in young women with depression, entitled Momentary Affect Regulation - Safer Sex Intervention (MARSSI). MARSSI was developed by Dr. Lydia Shrier of Boston Children's Hospital. MARSSI has three components. The first is a manualized session with a sexual and reproductive health counselor, who uses motivational interviewing (MI) techniques to help the young woman identify a risk-reducing goal for her sexual behavior, develop a change plan, and provide depression education and skills, based on cognitive behavioral therapy. The second component is a mobile health (mhealth) application that the young woman loads on her smartphone and, for four weeks, uses to complete app-prompted reports 3 times a day and a scheduled report once a day. When she reports poor affect, low contraceptive or condom self-efficacy, pregnancy desire, or desire for sex to regulate affect, she receives personalized messages prompting healthy behaviors and cognitive behavioral skill use. The third component is a booster session that occurs after 4 weeks of app use. The young woman meets with the counselor again to review her behavior and relationships, discuss progress toward her goal, and learn a new skill. Through these components, MARSSI aims to enhance motivation to change risk behaviors, provides skills to address depression's effects on behavior, and prompts and reinforces healthy affect regulation, cognitive behavioral skill use, and behavior change in daily life.

The Policy \& Research Group (PRG) will conduct an implementation evaluation and an impact evaluation, using an individual randomized controlled trial, to test the efficacy of this new intervention. The study will target young women ages 16-21 who have depressive symptoms and are recent clients of sexual and reproductive health clinics. The primary focus of the study will be to investigate the impact of the intervention on three self-reported sexual behaviors: 1) condom use; 2) use of effective contraception; and 3) number of sexual partners. The study will also include exploratory investigations of a number of other sexual behaviors and theoretically relevant antecedents to change in behavior and sexual health, including but not limited to: 1) engagement in protective sexual behavior; 2) condom use at last vaginal sex; 3) effective contraceptive use at last vaginal sex; 4) dual methods of protection; 5) frequency of vaginal, anal, and oral sex; 6) substance use before any type of sex; 7) types of sexual partners/relationships; 8) depressive symptoms; 9) sexual communication self-efficacy; 10) motivation to change risky sexual behaviors; 11) contraceptive and condom knowledge; 12) contraceptive and condom planning self-efficacy; and 13) use of cognitive restructuring.

Outcomes will be assessed using self-reported, participant-level data gathered (by way of a questionnaire) at four time points: baseline (enrollment); post-program (immediately after the end of the intervention period; 1 month post baseline); short-term (4 months post-baseline) follow-up; and long-term (7 months post baseline) follow-up.

Starting in June 2021 and continuing for 23 months, 600 participants who have received reproductive health care in the past two years (nationally) will be recruited and enrolled into the study by trained Planned Parenthood research coordinators. The final year of the grant will be used to complete the following tasks: collect follow-up data from study participants; conduct implementation and impact evaluation analysis, reporting, and dissemination efforts; and manualize and package the curriculum and training materials.
