ZAVALETA-RAMIREZ, Patricia et al. K-SADS-PL-2009/Autism spectrum disorders (ASD) inter-rater reliability. Salud Ment [online]. 2014, vol.37, n.6, pp.461-466. ISSN 0185-3325.

Autism spectrum disorders (ASD) have demonstrated an increase in prevalence and are no longer considered a rare condition. The Autism Diagnostic Interview-Revised (ADI-R) and the Autism Diagnostic Observation Schedule-Generic (ADOS-G) have been gold standard instruments to diagnose ASD, but neither of these tools identifies associated comorbidity. The new Kiddie Schedule for Affective Disorders and Schizophrenia for School-Age Present and Life time version (K-SADS-PL-2009) added a supplement for assessing ASD. Objective The purpose of this study was to translate, adapt and analyze the interrater reliability of the KIDDIE SADS-PL-2009/ASD. Method The sample consisted of 40 children and adolescents, both male and female, with an age range between four and 17 years old, and presumptive ASD diagnosis. The original ASD screen and supplement interview was translated in to Spanish by two of the authors and retranslated by a certified translator blind to the study. Results Inter-rater reliability: Intraclass correlation coefficients varied from moderate to excellent for the following diagnosis both in the present and the past: Autism 0.79, 0.74; Asperger 0.85, 1.0; PDDNOS 0.72, 0.41. Kappa coefficients for expert evaluations in the present and the past were as following: Autism 0.89, 0.87; Asperger 0.77, 1.00; PDDNOS 0.69, 0.64. Diagnostic concordance between the initial clinical diagnosis and the following diagnosis through the interview was: 37.5%, with a 67.5% error margin. Conclusions In this study, the K-SADS-PL-2009/ASD showed moderate inter-rater reliability indicating that it can be used for clinical or research purposes in Mexican children and adolescents.
