The aim of this study was to explore the psychometric properties of the Young Schema Questionnaire-Short Form 3 (YSQ-SF3) among Turkish adolescents. A total of 356 high school students (198 females and 158 males) whose ages ranged between 15 and 18 participated in the study, and were administered the YSQ-SF3, the Trait Anxiety Inventory (STAI-T), the Trait Anger Inventory (ANG-T), and the Positive and Negative Affect Schedule (PANAS). Higher-order factor analysis run using the original 18 Early maladaptive Schemas (EMSs) revealed three internally consistent higher-order factors (i.e., schema domains) which were named Impaired Limits-Exaggerated Standards, Disconnection-Rejection, and Impaired Autonomy-Other Directedness. Concurrent validity analyses indicated that even after controlling for the effects of positive and negative affect, the Impaired Limits-Exaggerated Standards schema domain was significantly associated with anger, while Disconnection-Rejection and Impaired Autonomy-Other Directedness schema domains were significantly associated with anxiety. Findings are discussed in line with the literature.
