The validity and reliability of the Turkish version of the Family Nutrition and Physical Activity screening tool

Objective: The aim of this study is to evaluate reliability and validity of the Turkish version of the Family Nutrition and Physical Activity (FNPA-TR) screening tool. This study was conducted as a methodological research. The data were collected between May and June 2018. The population of the study consisted of 1126 first and fourth grade students and their families in three primary public schools that represent three socioeconomic statuses (high, medium, low) in Istanbul, Turkey. Materials and Methods: Data were collected from 727 students and their families with an introductory information form and the FNPA-TR screening tool. The validity of content scale was evaluated by comparing the relationship between FNPA-TR scores and answers given to non-scale questions measuring the eating behaviour. In this study, Cronbach's alpha, Kaiser-Meyer-Olkin, Varimax rotation and ICC coefficients statistical tests were used to measure validity and reliability. Results: The Cronbach alpha coefficient for the internal consistency of the scale was 0.724. The test-retest reliability coefficient of the scale had a medium to very high level that ranged from 0.422 to 0.925. The Kaiser-Meyer-Olkin test result was found to be appropriate as 0.771. Conclusion: The study shows that the FNPA-TR scale is a valid and reliable measurement tool for the Turkish population.
