Abstract
Background and objective: The aim of this study is to determine the validity and reliability of the gestures section of the MacArthur–Bates Communicative Development Inventory-infant form for 8 to 16 month old Persian-speaking infants in Isfahan-Iran.
Methods: This is a validation study to determine content validity, internal consistency and test-retest reliability of the gestures section. Ten speech language pathologists were asked to comment and score the clarity, simplicity and relevance of the items. Lawshe’s method was used to analyze their scores to determine their content validity ratio (CVR). The administration limits and internal consistency were studied by asking 11 and 115 parents randomly selected, respectively to complete the revised checklist. To determine test-retest reliability the checklist was re-completed by 30 parents within a 15-30 days interval between test and retest phases.
Results: The calculated CVR for the gestures section is 0.91.Chronbach’s alpha shows %962 internal consistency between all items and the test-retest reliability is %925.
Conclusions: All psychometric features are highly acceptable which document the appropriate content validity, internal consistency and test-retest reliability of the gestures section of the infant form of CDI.
