en General پژوهشي Research Article Background: Sexual dysfunction is one of the most common complications of spinal cord injury with potentially negative impacts on sexual satisfaction.Objectives: This study aimed to compare the effects of app-based and lecture-based sexual education on the sexual satisfaction of disabled men with spinal cord injury.Methods: A randomized clinical trial was conducted on disabled men with spinal cord injury in 2019. The participants were selected using a convenience sampling method from the Welfare Organization of Birjand city. A demographic form and Larson&rsquo;s Sexual Satisfaction Questionnaire were completed before the intervention. Then, the participants were randomly assigned to two groups (app-based and lecture-based groups). In the app-based group, the sexual education content was prepared as an Android app that was accessible for the group participants for two months. Similar content was communicated to the lecture-based group in the form of lectures during ten 60- to 90-min sessions over two months. Six weeks after the end of the intervention, Larson&rsquo;s Questionnaire was completed again for both groups. Data were analyzed using the Fisher&rsquo;s exact test, Kolmogorov-Smirnov test, paired t-test, and independent t-test. The significance level was set at P < 0.05.Results: In both groups, the mean scores of sexual satisfaction significantly increased after the intervention (P < 0.05). Nevertheless, the mean change in the sexual satisfaction score was significantly more in the app-based group (18.16 &plusmn; 3.31) than in the lecture-based group (7.52 &plusmn; 4.59) (P < 0.05).Conclusions: App-based sexual education can be more effective than lecture-based sexual education in improving the sexual satisfaction of disabled men with spinal cord injury.
