This study aims to determine the effect of acceptance and commitment-based counseling on sexual performance and satisfaction in young couples compared to the conventional counseling currently provided in premarital counseling centers. This clinical trial with control and case groups will be conducted with 60 couples, selected purposively if they meet the inclusion criteria, and then randomly and evenly divided into control and case groups (30 each). Intervention is conducted in three stages. Each stage will include 20 couples in control and case groups, who will receive conventional and commitment-based premarital counseling respectively. After completion of educational sessions, the results of sexual satisfaction and function questionnaire completed by both control and case groups will be compared. Study inclusion criteria are the following: minimum high school diploma education, 20-30 years old, and couples planning to live together in the next two weeks. Study exclusion criteria are the following: unwillingness to participate due to personal reasons, illness, or a disorder that prevents individuals from attending educational sessions.
Interventions will comprise eight two-hour sessions. The first six sessions will involve commitment-based group counseling for both men and women, and in the last two sessions, sexual relationship will be taught to men and women separately. In this study, the sexual function and satisfaction intervention will be provided through commitment-based counseling, with sexual function and satisfaction as the main outcomes.
