Participants were selected through multistage cluster sampling. Data were collected using the 42-item Ryff Psychological Well-Being Scale, the Balanced Cohesion Scale of FACES IV, the Friends subscale of the Multidimensional Scale of Perceived Social Support, and the Rosenberg Self-Esteem Scale. Data were analyzed using IBM SPSS Statistics and AMOS. Pearson correlation analysis, confirmatory factor analysis, and structural equation modeling with maximum likelihood estimation were performed. Indirect effects were examined using bias-corrected bootstrapping with 5,000 resamples.</p> <p><strong>Findings:</strong> The structural model demonstrated acceptable fit, χ²/df = 2.36, CFI = .946, TLI = .940, RMSEA = .052, and SRMR = .045. Family cohesion significantly predicted self-esteem (β = .39, p &lt; .001) and psychological well-being (β = .22, p &lt; .001), while peer support significantly predicted self-esteem (β = .34, p &lt; .001) and psychological well-being (β = .18, p &lt; .001). Self-esteem had the strongest direct effect on psychological well-being (β = .49, p &lt; .001). Significant indirect effects on psychological well-being through self-esteem were observed for family cohesion (β = .19, p &lt; .001) and peer support (β = .17, p &lt; .001). The model explained 39.8% of the variance in self-esteem and 58.7% of the variance in psychological well-being.</p> <p><strong>Conclusion:</strong> Adolescent psychological well-being is associated with both interpersonal resources and positive self-evaluation, with self-esteem partially mediating the effects of family cohesion and peer support.</p> </td> </tr> </tbody> </table> https://journals.kmanpub.com/index.php/jayps/article/download/6231/11938
