Outline
To develop a scale measuring parents’ attitudes towards their children’s dietary health and to test its reliability and validity. This study aims to provide a scientific tool for assessing parents’ attitudes towards their children’s dietary health.
According to the Health Belief Model, an initial item pool was created for the scale. A research team was assembled, and through processes such as consulting with experts, the preliminary version of the scale was established. A staged cluster sampling method was employed to select a total of 40 classes from grades 4 to 8 in primary and secondary schools in Chengdu’s Xindu District between May and October 2023. Initially, an item analysis was conducted using all 2 651 collected samples. Then, the entire sample set was randomly split into two subsets: Sample 1 (n=2 091) was subjected to exploratory factor analysis first, and Sample 2 (n=560) was subjected to confirmatory factor analysis. Finally, the total sample was used for internal consistency testing. Two weeks after the survey, parents in a random class were randomly selected to refill the questionnaire to obtain the test-retest reliability of the scale.
The final version of the scale included 24 items. EFA extracted six common factors (perceived susceptibility, perceived severity, perceived benefits, perceived barriers, self-efficacy, and cues to action), with a cumulative variance contribution rate of 82.433%. CFA results showed: χ2/df=2.641, RMSEA=0.055,GFI=0.913, AGFI=0.890, TLI=0.964, IFI=0.969, and CFI=0.969. The overall Cronbach’s α coefficient was 0.934, the split-half reliability was 0.813, and the test-retest reliability was 0.641. Children’s dietary behavior was significantly associated with parents’ attitudes scores (P<0.05).
The scale developed in this study demonstrates good reliability and validity, and is suitable for assessing parents’ attitudes towards the dietary health of school-aged children in community family settings.
