Background: Due to the prevalence of visual-motor disorders among preterm children, the negative effects of these disorders on the quality of motor function and the importance of visual-motor skills in performing daily tasks, A reliable and valid tool is needed to measure these skills in these people. The aim of the present study was to evaluate the Psychometric properties and standardization of the Persian version of the third edition visual-motor skills test in preterm children.
Methods: For this purpose, 2100 students were selected from 7 to 12 year old students all over the country by multi-stage cluster random sampling method and of these, 376 preterm children (<32 weeks gestation) were purposefully selected.The measurement tool of this study was the third-edition visual-motor skills test, which was performed twice, three weeks apart, on the research samples. Formula Z was used to calculate the percentage points for each age group. Cronbach's alpha coefficient was also used to determine internal consistency and intra-class correlation in test-retest method was used for test time reliability.
Results: The results of this study indicate the appropriate validity of the 3-motor vision skills test for all age groups 7 to 12 years in preterm children. Also, the results of this study indicate the desired and acceptable internal consistency and time reliability or reproducibility of this test.
Conclusion:. The visual-motor skills test 3 has appropriate validity and reliability for screening and identifying premature children with visual-motor skills disorders.

Measuring different types of aggression (such as physical, verbal) and its functions (such as Reactive/Proactive) in individuals with developmental disabilities, especially adolescents and adults, has received little attention. In this study, we investigated the validity and reliability of the Persian version of the Children’s Scale of Hostility and Aggression: )Reactive/Proactive) in individuals with and without autism spectrum disorder in different age groups. For this purpose, C-SHARP questionnaire, child behavior checklist (CBCL) and reactive/Proactive aggression questionnaire were filled out by different age groups with autism spectrum disorder and other developmental disabilities. Different types of validity were determined with test-retest and Cronbach's alpha for its external and internal reliability. Correlation between C-SHARP, CBCL and reactive/Proactive aggression questionnaire was also used to assess the validity of the C-SHARP scale. The correlation coefficient between C-SHARP subscales and CBCL Externalizing was higher than internalized CBCL. Individuals classified with the reactive/Proactive aggression questionnaire as both Reactive and Proactive have higher C-SHARP Proactive Scores than individuals classified as Reactive only or Reactive or Non- Proactive. For C-SHARP reaction scores, a similar pattern was observed for proactive scores. The results of this study provided evidence for the validity of C-SHARP by confirming the content validity and its relationship with valid scales, which shows that C-SHARP is useful for measuring different types of aggressive behavior in different age groups with developmental disabilities
