Only two studies have investigated the diagnostic utility of the Autism Spectrum Rating Scale-2-5 parent report (ASRSp 2-5), and in both of these studies, the use of a gold-standard ASD measure in the diagnostic process is unclear. Method The current study investigated the criterion validity of the ASRSp-2-5 in a clinical sample of 238 children (X¯ age = 3.66; autism[AUT] n = 84; non-autism[NOT] n = 154). Children were diagnosed via a comprehensive assessment that included the Autism Diagnostic Observation Schedule-2. Results Analyses included t-tests/ANCOVAs, Logistic Regression (with and without covariates), and ROC analyses (with t-scores and predicted probabilities to account for covariates). The ASRSp 2-5 scores intended to be used for diagnosis (Total and DSM-5) were non-significant in all analyses. Higher scores in the NOT group were found for Unusual Behavior and Behavioral Rigidity. However, mean differences were non-significant with inclusion of control variables (IQ and age). Social, Peer Interaction, and Social-Emotional Reciprocity demonstrated the strongest findings. The ASD group had significantly higher scores on these scales, and findings held with covariates included (IQ for Social; age for Peer Interaction). However, odds ratios were small whether or not covariates were included, and AUCs were poor-fair (.69–.70). Sensitivity and specificity could not both be optimized at any cutpoint. Conclusions The findings were not as strong or as consistent as expected. Results suggest the ASRSp 2-5 is most useful in ruling out ASD in cases of low scores (<60). When the ASRSp 2-5 is utilized, behavioral, social, and emotional problems associated with other disorders must be considered in interpreting scores. Additional research on this measure is necessary.
