Due to the fact that adolescence is associated with psychological stress due to students' mental and psychological activities, such as entering university and future careers, etc., and this psychological stress can affect their physical and mental health. Therefore, in this study, the effectiveness of mindfulness training on sleep quality and mental health of Girl Students Participating in the National Exam has been investigated. This study was a quasi-experimental study of pretest-posttest type with experimental and control groups and follow-up test. The statistical population included all Girl Students Participating in the National Exam (12th grade) in Yazd in the academic year 2022-2023, 27 of whom were selected by convenience sampling method and were randomly assigned to experimental and control groups. The experimental group received 6 sessions of mindfulness training and the control group did not undergo any intervention. The Pittsburgh Sleep Quality Questionnaire (PSQI) and the General Health Questionnaire (GHQ-28) were used to collect research data. The data obtained from the questionnaires were analyzed at two levels of descriptive statistics (frequency, mean, standard deviation) and inferential statistics (analysis of variance with repeated measures) by SPSS-23 statistical analysis software. The results showed that mindfulness training significantly improved the quality of sleep and mental health of Girl Students Participating in the National Exam.

Risky behavior among adolescents is a common problem requiring attention and preventive interventions. Numerous studies support the contribution of cognitive and emotional deficits in the tendency to high-risk behaviors. This study aimed to predict risk-taking behaviors through decision-making styles and difficulty in emotion regulation among female adolescents. For this purpose, 200 high school students (Mage = 15. 23, SD = 1. 00) were selected via a stratified random sampling method. Participants completed the Iranian Adolescence Risk-taking Scale (IARS), General Decision-Making Style (GDMS) questionnaire, and Difficulty in Emotion Regulation Scale (DERS). Findings indicated that risky behaviors significantly correlated with difficulty in emotion regulation. In addition, high-risk behaviors demonstrated a positive correlation with spontaneous decision-making and a negative correlation with rational decision-making style. The results of multiple linear regression analysis revealed the significant role of decision-making styles and difficulty in emotion regulation in predicting high-risk behaviors. Practical implications and future areas of study are discussed.
