This study employed a descriptive survey method to explore the mediation effect of graduates self efficacy in association with metacognition and mental health among graduates. Total of 211 graduates made up the study group, and data were collected through convenience sampling. The inquiry made use of the Baron and Kenny approach of mediation analysis. Among the reliable and valid research tools employed were the Positive Mental Health Inventory, the Metacognition Inventory Scale (MCI), and the General Self Efficacy Scale. Findings indicated that although self efficacy, metacognition, and mental health were positively correlated, their relationship was not very strong. The regression coefficients indicated that there might not be a causal relationship between the variables. Although the entire model for predicting self-efficacy did not show statistical significance, there was a strong correlation between self-efficacy and mental health. According to a study that looked at how self-efficacy affected the association between metacognition and mental health, the indirect effect was responsible for 30% of the difference between the direct and total effects. The findings indicate a weak but positive correlation between self-efficacy, mental health, and metacognition, but the correlations are insufficient to demonstrate a causative link. Self-efficacy was discovered to mediate the association between metacognition and mental health in a statistically significant way. It is necessary to conduct more study to examine additional causes and treatment options for improving wellbeing.
