Actual date on which the first participant was enrolled.

This study investigates an 8-week online program designed to help couples experiencing distress due to sexual desire discrepancies, which is when partners have different levels of sexual interest. The program, named STEP, is tested in two versions: one with guidance from a therapist (STEP-T) and one that is self-directed (STEP-NT). Couples participating in the study are randomly placed in either version of the program or put on a waiting list as a control group. The study's goal is to see if these programs can reduce distress, improve sexual satisfaction, and enhance relationship satisfaction over a six-month period. This research is important as it seeks to offer effective ways for couples to manage and improve their intimate relationships when faced with challenges around sexual desire. Participants in the study start by completing online questionnaires to establish a baseline of their current relationship status and experiences. Those in the therapist-guided group meet with a therapist online every week, while those in the self-guided group receive weekly modules via email. Both groups engage in activities like completing worksheets on sexual beliefs and participate in assessments to track their progress. The study also evaluates how engaged participants are with the program and whether their improvements last over time. Researchers send follow-up emails to ensure participation and gather feedback on the program's effectiveness and satisfaction levels. This approach allows an in-depth understanding of how each intervention format impacts couples' relationships and what additional factors might contribute to successful outcomes.
