摘要

Purpose

The subthreshold autism trait questionnaire (SATQ) is a brief self-report measure designed to assess subthreshold autistic traits in the general population. While several parent-report instruments have been validated in Turkish, no self-report tool has been adapted for adolescents. This study aimed to translate, culturally adapt, and examine the psychometric properties of the Turkish version of the SATQ for adolescents aged 12–18 years.

Method

A cross-sectional, multicenter case–control design was employed with 412 adolescents (143 patients, 269 non-clinical controls). Following translation and back-translation, the Turkish SATQ underwent item analysis, reliability testing, exploratory and confirmatory factor analyses, criterion validity evaluation, and ROC analysis. Two items were removed due to cross-loadings, yielding a 30-item version (SATQ-TR).

Results

The SATQ-TR showed good internal consistency (Cronbach’s α = 0.74) and excellent test–retest reliability (r = 0.92). Item discrimination analyses were significant for all items (p < 0.001). Exploratory factor analysis identified a seven-factor structure explaining 53.5% of the variance (KMO = 0.86, p < 0.001), and confirmatory factor analysis indicated acceptable model fit (RMSEA = 0.071; CFI = 0.93; TLI = 0.92; NFI = 0.90; GFI = 0.95). ROC analysis demonstrated satisfactory discriminative ability for ASD (AUC = 0.73, 95% CI 0.60–0.86). Significant correlations between SATQ and AQ scores supported criterion validity.

Conclusion

The 30-item Turkish version of the SATQ (SATQ-TR) is a valid and reliable tool for assessing subthreshold autistic traits in adolescents. By providing a brief, multidimensional self-report measure, it fills an important gap in Turkish adolescent populations and supports early identification and dimensional approaches in autism research and practice.
