Objectives: This research was carried out to investigate the effectiveness of sexual education based on mindfulness and Islamic teachings in increasing self-esteem and its related components among female adolescents. Methods: This quasi-experimental research was conducted using a pretest-posttest design with a control group. A total of 60 subjects were selected by cluster random sampling method and assigned into three groups of 20 individuals. The groups were tested and matched before the intervention. Then, the experimental groups were trained using mindfulness and Islamic teaching-based sexual education in eight sessions of 90 min. The Pops' self-esteem questionnaire was used for data collection. The reliability of the questionnaire was obtained between 0.51 and 0.75 and the validity of the questionnaire was confirmed by internal consistency. Results: The mean score was higher in the Islamic teachings group than in the other groups and the mean score of the mindfulness group was higher than that of the control group. Therefore, research hypotheses were confirmed regarding the effectiveness of sexual education based on mindfulness and Islamic teachings in increasing self-esteem and its components. The results showed that mindfulness and Islamic teaching-based sexual education are effective in increasing the components of adolescents' self-esteem. Conclusions: Therefore, it can be concluded that the implementation of sexual education is essential in the curriculum context.

Background: Sexual identity is an individual's sense of masculinity or femininity that has a positive effect on his/her mental health and well-being. Objectives: The current study aimed at providing sex education based on mindfulness training and Islamic teachings in improving satisfaction with sexual identity among Iranian male adolescents aged 12-15 years. Methods: The current quasi-experimental study with a pretest-posttest design and a control group was conducted on a sample of 60 male adolescents selected using a multistage cluster sampling method, and every 20 subjects were randomly assigned to an experimental or a control group. The measurement tool was a researcher-made questionnaire on satisfaction with sexual identity to measure four emotional, perceptual, behavioral, and social subscales. Cronbach's alpha coefficients of the whole questionnaire and the subscales were 0.76 and 0.65, respectively. Its validity was confirmed by internal consistency. Results: Results of analysis of covariance showed that the scores of the groups were significantly different in satisfaction with sexual identity and its perceptual and social subscales. There was a significant difference between the experimental group trained by Islamic teachings and the control group in the emotional subscale. Concerning all of the subscales, the means of the experimental group trained by Islamic teachings were higher than those of the group received mindfulness training. Conclusions: According to the current study results, it can be concluded that sex education based on mindfulness training and Islamic teachings should necessarily be considered in school curriculums developed for adolescents to improve their mental health and prevent them from social harm.
