Abstract
OBJECTIVE AND BACKGROUND: Mental health is a widespread field that entails variables such as the presence of positive feelings like satisfaction with life and lack of negative emotions like depression, anxiety, and stress. This research aimed to study the prevalence of depression, anxiety, stress, and satisfaction with life as dimensions of adolescent girls' mental health in Tehran. METHODOLOGY: The population considered in this cross-sectional study consisted of adolescent girls in the last grade of high school in Tehran. Research samples were selected using multi-stage sampling. The sample size in this study was 491 and the research tools used were standardized questionnaires. Descriptive and inferential statistics included Spearman, ANOVA, and regression tests were used. FINDINGS: More than half of the adolescents experienced common symptoms of depression, anxiety, and stress. About 30% of adolescents were dissatisfied with life to some extent. Satisfaction with life was negatively correlated with age, depression, anxiety, and stress. Age and depression were predictor variables of life satisfaction based on the regression model. CONCLUSION: A considerable percentage of adolescents suffered some form of depression, anxiety, and stress symptoms and were notably dissatisfied with life. Regarding the importance of satisfaction with life in having a joyful life and its role in initiating depression, anxiety, and stress, our findings highlight the need for interventions to prevent depression, anxiety, and stress and enhance life satisfaction among adolescents.
