Recent literature suggests that poor self-image is related to various types of mental disorders among adolescents and young adults such as depression. In this sense, this study investigates self-image and psychological well-being among seventy two adolescents in Turkey. The first purpose of this study is to evaluate psychometric properties such as factor structure, reliabilities and validity of Self-Image Questionnaire for Young Adolescents. The second purpose of this study is to investigate the relationships between mental health problems such as depressive symptoms and three important constructs of selfimage: (a) social relationships, (b) emotional tone and (c) body image. To argue the reliability of analysis, exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were made. The multiple regression analysis was conducted for the second purpose of this study. Using scale from CDI describing depressive symptoms as dependent variable, its associations with subscales in SIQYA such as family relationships, peer relationships, emotional tone and body image were examined. All the analyses were performed using SPSS except that confirmatory factor analysis was conducted using SAS. Results indicate that there is a significant negative relationship between depressive symptoms and social relationships among Turkish adolescents, and much more.
