Background & Aim: Sexual function is an important part of the health of women, and the satisfaction of basic psychological needs is among the variables related to sexual dysfunction. The self-determination theory is one of the most important motivational theories, which considers one’s internal motive the main cause of behavior, and also views three psychological needs (autonomy, relatedness, and competence) as the basis of human behavior. This study was to determine the effect of sexual consulting based on the self-determination theory on women’s sexual function.
Methods & Materials: This clinical trial was conducted on 104 married women aged 18 to 49 years referred to Mashhad health centers in two groups of intervention and control in 2019. The intervention group received five sessions of two-hour group counseling based on the constructs of self-determination theory, with intervals of one week. The data was collected using the sexual performance questionnaire and the constructs of self-determination theory (basic psychological needs) before and after the intervention. Data was analyzed using the SPSS software version 16 through independent t-test, paired t-test, Mann-Whitney and Wilcoxon tests.
Results: There was no statistically significant difference between the two groups in the average score of sexual function before the intervention. However, after the intervention, the difference in the average score of sexual function between before and after the intervention was 2.76±3.02 for the intervention group and -0.25±0.73 for the control group, which showed a significant increase in the sexual function score of the intervention group compared to the control (P<0.001). Moreover, after the intervention between the intervention and control groups, a statistically significant difference was observed in the average scores of autonomy, competence and relatedness (P<0.001).
Conclusion: Providing group sexual counseling based on the self-determination theory can satisfy the basic needs relating to sexuality and improve women's sexual performance.
