The social responsiveness scale in relation to DSM IV and DSM5 ASD in Korean children

Abstract

LAY ABSTRACT The Social Responsiveness Scale(SRS) is an autism rating scales in widespread use, with over 20 official foreign language translations. It has proven highly feasible for quantitative ascertainment of autistic social impairment in public health settings, however, little is known about the validity of the reinforcement in Asia populations or in references to DSM5. The current study aims to evaluate psychometric properties and cross-cultural aspects of the SRS-Korean version (K-SRS). Our results indicate that the K-SRS exhibits adequate reliability and validity for measuring Autism Spectrum Disorder (ASD) symptoms in Korean children with DSM IV PDD and DSM5 ASD. Our findings further suggest that it is difficult to distinguish Social Communication Disorder (SCD) from other child psychiatric conditions using the K-SRS. This is the first study to examine the relationship between the SRS subscales and DSM5 based clinical diagnosis. This study provides cross-cultural confirmation of the factor structure of ASD symptoms and traits measured by the SRS. SCIENTIFIC ABSTRACT The Social Responsiveness Scale(SRS) is an autism rating scales in widespread use, with over 20 official foreign language translations. It has proven highly feasible for quantitative ascertainment of autistic social impairment in public health settings, however, little is known about the validity of the reinforcement in Asia populations or in references to DSM5. The current study aims to evaluate psychometric properties and cross-cultural aspects of the SRS-Korean version(K-SRS). The study subjects were ascertained from three samples: a general sample from 3 regular education elementary schools(n=790), a clinical sample(n=154) of 6–12-year-olds from four psychiatric clinics, and an epidemiological sample of children with ASD, diagnosed using both DSM IV PDD, DSM5 ASD and SCD criteria(n=151). Their parents completed the K-SRS and the Autism Spectrum Screening Questionnaire(ASSQ). Descriptive statistics, correlation analyses and principal components analysis (PCA) were performed on the total population. Mean total scores on the K-SRS differed significantly between the three samples. ASSQ scores were significantly correlated with the K-SRS T-scores. PCA suggested a one-factor solution for the total population. Our results indicate that the K-SRS exhibits adequate reliability and validity for measuring ASD symptoms in Korean children with DSM IV PDD and DSM5 ASD. Our findings further suggest that it is difficult to distinguish SCD from other child psychiatric conditions using the K-SRS. This is the first study to examine the relationship between the SRS subscales and DSM5-based clinical diagnoses. This study provides cross-cultural confirmation of the factor structure for ASD symptoms and traits measured by the SRS.

Validation of the Social Responsiveness Scale (SRS) to screen for atypical social behaviors in juvenile macaques

“…Analysis of the distribution of jmSRS total scores (sum of scores of all items per subject) revealed positively skewed, not normally distributed total scores, similarly to the adult mSRS (28) and the human SRS (37)(38)(39). This result indicates that very few animals (6.5%) received very high total jmSRS scoresbetween 34 and 48-(i.e.…”

Aberrant Neural Activation Underlying Idiom Comprehension in Korean Children with High Functioning Autism Spectrum Disorder

“…In order to distinguish between TDC and children with ASD clearly, we applied a social responsiveness scale to TDC and excluded children with a score of 40 or more: the scale has proven feasibility for quantitative ascertainment of autistic social impairment in public health settings. 21 None of the TDC had past or current developmental, medical, or psychiatric diagnoses. All participants were right-handed native speakers of Korean and had normal or corrected-to-normal vision.…”

Assessing the Relation between Plasma PCB concentrations and Elevated Autistic Behaviours Using Bayesian Predictive Odds Ratios

“…The Social Responsiveness Scale-2 (SRS-2) was the dependent variable in our analysis, a valid and reliable caregiver-reported questionnaire that provides a quantitative measure of autistic behaviour and, at higher scores, differentiates autism from other disorders [28]. The SRS score has been cross-validated in a large European sample of clinical ASD cases [29], and it has been compared with the Diagnostic and Statistical Manual of Mental Disorders (DSM) [30]. The…”
