Aimed to determine the effect of sexual education based on the EX-PLISSIT model on sexual function and sexual satisfaction in women with multiple sclerosis.

The present study was a pretest-posttest randomized controlled study. Conducted between June and August 2023 in Turkey. The participants were MS patients who were women 18-49 years old. The intervention (n = 20) and a control group (n = 20). The intervention group received sexual counseling based on the EX-PLISSIT model. The model consists of four levels. The levels are permission, limited information, specific suggestions and intensive therapy. Counseling was presented in six to eight sessions according to the women's sexual problems. The Female Sexual Function Index (FSFI) and the New Sexual Satisfaction Scale were used to measure the sexual function and sexual satisfaction of the participants.

Data were analyzed using the Statistical Package for the Social Sciences (SPSS) version 21. P values below 0.05 were considered statistically significant.

Within the scope of this research, sexual counseling, based on the extended (EX-PLISSIT) model was offered to women for 6-10 weeks (until a solution was achieved). The EX-PLISSIT model is based on the core concepts of the PLISSIT model. The PLISSIT model is an effective, convenient and cost effective counseling method. This model was designed by Annon (1976) and includes the stages permission, limited ınformation, specific recommendations and intensive therapy. It is known that the PLISSIT model is effective for SD. The PLISSIT Model has been updated and expanded because it offers one-way, passive interaction. While counseling is linear in the PLISSIT model, it is feedback-oriented in the EX-PLISSIT model. This is one of the reasons why the EX-PLISSIT model is superior to the PLISSIT model. Unlike PLISSIT's linear mode; The EX-PLISSIT model is done in a cyclical manner. In other words, it is an interactive and repetitive model. All interventions must begin with "Permission." Each stage of "Limited Information", "Special Recommendation" and "Intensive Therapy" is supported by "Allowing". Thus, the interaction between counselors and clients is improved. While in the PLISSIT model, a direct transition can be made from one step to another, in the EX-PLISSIT model, the permission stage is at the center of the other stages and techniques such as review, and examination are used to increase the client's self-awareness. The EX-PLISSIT model is a practical guide for nursing research and practice.
