The purpose of this research is to investigate how subjective well-being, optimism and resilience affect adolescences' levels of self-efficacy. The second purpose of this research is also to investigate the difference between demographic variables in terms of gender, grade and fields of study. 502 chosen students by convenient sampling method, aged 14 to 19, studying in Istanbul for the 2021-2022 academic year and enrolled in the 9th, 10th, 11th and 12th grades constitute the study group. Measurement instruments have utilized in the research were the Personal Information Form, General Self-Efficacy Scale, Adolescent Subjective Well-Being Scale, Optimism Scale and Adolescent Psychological Resilience Scale. The Independent Sample T-Test has used to determine whether there are any gender-related differences in the relationship self-efficacy, subjective well-being, optimism and resilience. To determine whether there is a significant correlation between self-efficacy, subjective well-being, optimism and resilience among grades and fields of study, One-Way Analysis of Variance (ANOVA) has used. Additionally, Post Hoc Scheffe Test has used among grades and fields of study. Pearson Moments Multiplication Correlation Analysis has used to determine between relationship self-efficacy, subjective well-being, optimism and resilience among age. In order to answer the main question of the research, Hierarchical Regression Analysis has applied to determine whether the self-efficacy of the participants has predicted by subjective well-being, optimism, resilience and whether the self-efficacy with optimism total scores of the participants has predicted by subjective well-being and resilience subscale scores. According to the research findings, there was no statistically significant difference between the adolescences' self-efficacy, subjective well-being, optimism and resilience based on the gender variable. Findings showed that self-efficacy, subjective well-being, optimism and resilience have differed significantly according to the class based on the grade.

Self-efficacy has positively and substantially connected with subjective well-being, subjective well-being sub-dimensions, optimism, resilience sub-dimensions and resilience based on the age.

Subjective well-being sub-dimension of life satisfaction and optimism have significantly predicted self-efficacy. Subjective well-being, optimism and resilience sub-dimension of persistence have significantly predicted self-efficacy. The limitations of this research has noted and the results have discussed within the context of the literature.
