Psychometric evaluation of the Chinese revised Sensory Integration and Praxis Tests in children with amblyopia.

Background: Children with amblyopia commonly present with sensory integration difficulties, however, there is a paucity of validated tools to assess these issues in this clinical population. This study aimed to evaluate the psychometric properties of the Chinese Revised version of the Sensory Integration and Praxis Tests (SIPT-R) for use in children with amblyopia. Methods: We conducted a psychometric validation study using baseline data from the China Amblyopia Behavioral Cohort (CABC). Participants included 629 children aged 4-9 years diagnosed with amblyopia; subtypes included bilateral ametropic (55.7%), anisometropic (38.8%), and strabismic amblyopia (5.6%). Based on severity, 32.1% were classified as mild amblyopia, 59.3% as moderate amblyopia, and 8.6% as severe. Because the learning ability subscale was only applicable to children aged 6 years and older, scale structure differed between age groups. Thus, reliability and validity were evaluated separately for the aged 4-5 and 6-9 years. Internal consistency and construct validity were examined Results: The SIPT-R demonstrated excellent internal consistency (Cronbach's α = 0.968 - 0.969) and strong subscale reliability (α = 0.906 - 0.959). All split-half coefficients exceeded 0.80. CFA indicated an acceptable model fit for both age groups: for aged 4-5 years, Conclusions: The Chinese revised SIPT-R demonstrates strong reliability and acceptable validity for screening sensory integration function in children with amblyopia. Further research should focus on refining specific subscales and evaluating additional psychometric properties, such as test-retest reliability and criterion validity.
