Abstract Objective To develop the joint attention parents self-rating scale（JAPS）, and assess its reliability andvalidity in the identification and screening of autism spectrum disorder（ASD）children. Methods We developed the JAPS through literature researching, in-depth interviewing, expert consulting, and entries screening methods. By using convenient sampling method, a total of 836 parents of typically developing children and 135 children diagnosed with ASD, were randomly selected to complete this survey. The reliability, content validity, and relevance validity of the JAPS were analyzed statistically. Results The internal consistency reliability of the JAPS was 0.90. The coefficients of the three dimensionswere all above 0.70. All the entries in high（top 27% of the scalescore）and low（last 27% of the scalescore）group weresignificantly different（P<0.001）, and there was a significantly positive association between all entries and the total score（r=0.38-0.82, P<0.01）. The exploratory factor analysis indicated that the relationship among entries was good, and the extracted 3 factors were consistent with the dimension-division previously envisaged. There was significant difference between the scores of typically developing children and ASD children. Moreover, a significantly negative correlation between JAPS score and childhood autism rating scale（CARS）score was found in ASD children（r=-0.912, P<0.001）. Conclusion The JAPS reveals good reliability and validity, which can be used as an early screening tool in children with ASD, and provide an effective monitoring tool for early intervention.
