Validity and Reliability of the Persian Version of Nutrition Screening Tool for Every Preschooler (NutriSTEP®) in Iranian Preschool Children.

BACKGROUNDS: To assess the validity and reliability of the Persian version of Nutrition Screening Tool for Every Preschooler (NutriSTEP®), a community-based nutrition screening tool in preschool children. DESIGN AND METHODS: A cross-cultural validation study was conducted on 192 Iranian preschool children in Mashhad, Iran. Forward and backward translation and face validity was assessed. Criterion validity was confirmed by nutritionist risk score which was determined by an expert physician. Content validity, construct validity and reliability of the Persian version was assessed as well. Receiver operating characteristic (ROC) curve was used to detect the reasonable cut-points for the Persian version. FINDINGS: Content validity index and ratio ranged between 0.9 and 1 and 0.63-1, which both were acceptable. NutriSTEP® scores were significantly different in the three categories of nutritionist risk scores (p = .007). Item-to-scale correlation analysis shows significant correlation between each item and the total score. A significant correlation was seen between test-retest scores of NutriSTEP® (r = 0.68, p < .001). In Persian NutriSTEP®, scores 27 and 31 seems to better reflect the nutrition risk in Iranian preschool children population and are suggested as cut-points; Therefore, scores lower or equal to 27 are determined as mild risk and 28-31 as moderate risk, while scores higher than 31 are categorized as high risk. CONCLUSION: The Persian NutriSTEP® questionnaire is both valid and reliable for the screening of nutrition risk in preschool children of the Iranian population. PRACTICE IMPLICATIONS: Health care professionals may use the NutriSTSP® tool to find nutritionally high risk children as an important step to prevent childhood obesity.

Evidence for the Validity of the Children's Attraction to Physical Activity (CAPA) Scale in Iranian Preschool Children.

PURPOSE: The escalating trend of overweight and obesity is a major global health challenge and needs particular attention. There are a number of reasons for this increase, but the dominant one appears to be the pandemic of physical inactivity. It is now clear that children's attraction to physical activity is an important promising factor in children's physical activity involvement. In this study, we aimed to cross-validate the long version of children's attraction to physical activity (CAPA) scale in Iranian preschool children. DESIGN AND METHODS: Evidence for the validity of the scale was based on face validity, content validity, and internal consistency. The scale was translated into Persian and underwent forward translation, synthesis of the translation and backward translation. Face and content validity were subsequently assessed on individuals and expert panels. A sample of 30 preschool children (5-6 years of age) were randomly selected from three kindergartens. Children were interviewed by their kindergarten teachers. RESULTS: Internal consistency for each of the five subscales of the CAPA scale was evaluated through Cronbach's alpha. The internal consistency was acceptable for most of the subscales when negative statements were excluded from the analyses. CONCLUSIONS: The results supported the use of modified version of Persian-language long CAPA scale for Iranian preschool children, with the deletion of negatively worded items. PRACTICE IMPLICATIONS: Health care professionals may use the CAPA when assessing the attraction of children toward physical activity and its potential involvement in childhood obesity.
