Abstract
Introduction: The Structured Interview of Psychosis Risk Syndromes (SIPS) was created to identify patients with Clinical High Risk for psychosis (CHR). This study aimed i) to translate and validate the Scale of Prodromal Syndromes (SOPS) in Turkish adolescents, ii) to explore the factor structure of the SIPS/SOPS in the adolescent population, especially focusing on those under the age of 15, iii) to generate a brief version of SIPS (SIPS-B). Methods: A total of 150 adolescents aged between 12 and 18 years, were consecutively interviewed using SIPS/SOPS. Patients with psychotic syndrome (n=20), psychosis risk syndrome (PRS) (n=59), and clinical controls (CC) (n=71) were included in the study. Results: Principal component analysis (PCA) yielded three latent factors, explaining 62.7% of the total variance in the whole clinical sample, including positive symptom factor, disorganized symptom factor, and negative symptom factor. The area under curve calculated in ROC analyses involving PRS and CC supported the four-item form of the SIPS-B (optimal cut-off=12.5, sensitivity=87%, specificity=80%). Conclusion: Our study results support the notion that the Turkish translation of SIPS/SOPS meets the reliability and validity criteria in Turkish adolescents. The SIPS-B could aid clinicians in their routine clinical practice to expedite referral procedures. Copyright:
