The purpose of this study was to determine the content validity, internal consistency, and construct validity of the Child Nutrition and Physical Activity (CNPA) screening tool for obesity risk. The sample consisted of 2230 children aged 2 to 18 years old, with about 39% of the children being overweight or obese. An expert panel supported the content validity of the CNPA screener. Principal component factor analysis of perception/confidence/importance items yielded 2 factors with acceptable internal consistency. Construct validity of the CNPA screener was supported by associations with weight status. The CNPA screener demonstrates moderate reliability and validity; thus, further development will be needed.
