Validity and reliability of the Turkish version of the parent perceptions of physical activity scale.

Background: The Parent Perceptions of Physical Activity Scale (PPPAS) is a scale developed to measure the physical activity perceptions of parents of children with neurodevelopmental disorders about their children. Turkish version of the PPPAS has yet to be established. The purpose of the present study is to examine the validity and reliability of the Turkish version of the PPPAS.

Methods: The study included 130 parents with neurodevelopmental children. In the validity analyses of PPPAS, language validity, content validity analysis, and confirmatory and explanatory factor analysis were performed for construct validity. In the reliability analyses, Cronbach alpha analysis was used for internal consistency analysis, and intraclass correlation (ICC) analysis was used for test retest.

Results: The validity index was calculated as 0.94. Since the factor loading of the three questions in the survey remained below 40%,these questions were removed. Construct validity was achieved for two primary subscales of the PPPAS. It was found that the ICC valuesfor the reliability analysis of the PPPAS showed a perfect fit at the level of 0.918 for the benefits of the physical activity subdimension, and the physical activity barriers subdimension showed a perfect fit at the level of 0.916 (p = 0.001).

Discussion: The Turkish PPPAS, which consists of two subscales, namely the benefits and barriers of physical activity, is valid and reliable. This tool can measure the physical activity perceptions of parents with preschool-age children with neurodevelopmental disorders in the Turkish population.
