Abstract

This study aims to investigate the psychometric properties of the social communication questionnaire (SCQ) in Iran by identifying children with autism spectrum disorder (ASD) who had Persian-speaking parents.Design/methodology/approachA case–control study was performed from June to August 2021 in Hamadan, Iran. The case group consisted of children who were examined by clinicians who used a coding scheme based on the DSM-V criteria for ASD by a psychiatrist. The control group consisted of non-ASD children who were asked to participate in the study. This study conducted the reliability, content and face validity to evaluate the psychometric properties of the tool. In the first step, Kaiser–Meyer–Olkin and Bartlett’s test were used to determine sampling adequacy and appropriateness of correlation matrix. In the second step, the exploratory factor analysis approach was used. The method of extracting the factors is done by using the varimax rotation method and selecting the number of factors using an eigenvalue and scree plot. Statistical analysis was performed using Software Package for Social Sciences 21 with the statistical significance set at level less than 0.05.FindingsThe quantitative content validity analysis revealed that the mean of content validity ratio and content validity index were 0.92 and 0.91, respectively. Mean score ± standard deviation in the two groups of ASD and control were 14.23 ± 3.84 and 7.83 ± 4.80, respectively. With cut-off point >12.5, sensitivity, specificity and misclassification error values were 73.33%, 80.0% and 23%, respectively.Research limitations/implicationsThe results showed that the internal consistency of the SCQ is desirable. Also, the internal consistency of its five subscales was obtained between 0.700 and 0.87. The findings showed that SCQ questionnaire is highly reliable in reciprocal social interaction (Factor 1) and the total score, while other factors were relatively reliable.Originality/valueTo the best of the authors’ knowledge, this is the first paper on psychometric properties of SCQ in ASD children in Iran.
