To assess the reliability of newly developed questionnaires measuring theoretical constructs believed to predict fruit and vegetable consumption among 6th–grade pupils.
Participating pupils and parents completed questionnaires twice, 14 days apart.
One hundred and twenty–nine pupils from 6th–grade classes (average age: 11.9 years) at two schools in Norway and their parents were invited to participate.
The test–retest reliability was found to be good or very good for scales reported both by the pupils and their parents. All scales showed acceptable to strong correlations between time 1 and time 2, and only one scale had significant different mean values at the two times. The internal consistency reliability of the scales was acceptable to good.
Sixth graders and their parents are able to provide reliable reports on theoretical determinants of the pupilapos;s fruit and vegetable consumption.
