The present study was conducted with the aim of evaluating the psychometric properties of the anxiety scale of children with autism spectrum disorder (parent form). The method of the current research was a correlational description. The statistical population of the present study was all children with autism spectrum disorder in Tehran city who were referred to autism education and rehabilitation centers in 2022. 315 children (193 boys and 122 girls) were selected using available sampling method. After translating and obtaining the opinions of experts and subjects, the face validity of the scale was confirmed. AMOS and SPSS software were used for statistical analysis. The results of confirmatory factor analysis showed that in the sample of Iranian children with autism spectrum disorder, the four-factor structure of the scale including performance anxiety, anxiety arousal, separation anxiety and uncertainty had a good fit with the data. The results related to the correlation between this scale and the Spence anxiety scale experimentally supported the convergent validity of the anxiety scale of children with autism spectrum disorder. The internal consistency coefficients of the whole scale and subscales of functional anxiety, anxiety arousal, separation anxiety and uncertainty were obtained as 0.79, 0.78, 0.81, 0.76 and 0.82, respectively. Overall, the results of the present study showed that the anxiety scale of children with autism spectrum disorder is a valid and reliable tool for measuring anxiety in Iranian children with autism spectrum disorder. This tool can be used to measure anxiety in Research and treatment sections.

Objectives: The aim of this study was to adapt and evaluate the psychometric properties of a Persian version of Developmental Coordination Disorder Questionnaire (DCD-Q) in Iran to identify children at risk for Developmental Coordination Disorder (DCD). Method: We examined the internal consistency, test-retest reliability construct validity, and concurrent validity of the DCD-Q using a large, primary school-based sample of boys and their parents’. A total of 922 parents completed the DCD-Q and 15 parents repeated it after 2 weeks for test–retest reliability. Scores on the DCD-Q were compared to performance on the Test of Gross Motor development-2 (TGMD-2). Concurrent validity was examined by calculating correlations between scores of the DCD-Q, and the TGMD-2.
Results: Two items deleted after the evaluation of the internal consistency. Deletion of these items increased Cronbach’s α to .85 and test–retest reliability to .93. Explanatory and confirmatory factor analysis showed that the DCD-Q was multifactorial and this version is compatible with the original version of the DCD-Q. Finally, high correlations were observed between the DCD-Q with the TGMD-2 subscales: locomotion (r = .65), object control (r = .60).
Conclusion and recommendations: These results support the validity and reliability of the Persian version of the DCDQ as a screening instrument for identification of children at risk for DCD in Iran.
