Abstract
Adolescence is a critical developmental period characterized by heightened vulnerability to emotional and psychological challenges, particularly during the transition to secondary education. This study examined the emotional and mental stability of Grade 9 students at Ginatilan National High School in Kidapawan City, Philippines, with the aim of identifying demographic differences and informing targeted school-based interventions. A quantitative research design was employed involving 100 Grade 9 students selected through random sampling. Data were collected using two standardized instruments: the Strengths and Difficulties Questionnaire (SDQ) and the Warwick–Edinburgh Mental Well-being Scale (WEMWBS). Descriptive statistics, Pearson correlation, regression analysis, and analysis of variance (ANOVA) were conducted using Jamovi statistical software. Results indicated that the overall mean SDQ score fell within the abnormal range, suggesting the presence of notable emotional and behavioral difficulties among the respondents. In contrast, WEMWBS scores reflected moderate levels of mental well-being. Significant differences were observed across age and gender groups, with female students and younger adolescents (aged 14) demonstrating higher levels of emotional difficulties. Regression analysis identified age and gender as significant predictors of emotional difficulties. In contrast, no significant predictors emerged for overall mental well-being, underscoring the complexity of factors influencing positive mental health. The findings highlight the prevalence of emotional and mental health concerns among early adolescents and emphasize the need for developmentally appropriate and gender-responsive interventions. This study contributes context-specific evidence to the growing literature on adolescent mental health. It supports the integration of comprehensive mental health programs within secondary school settings to promote students’ holistic well-being and academic success.
