Reliability of parental and self-reported determinants of fruit and vegetable intake among 6th graders.
OBJECTIVE
To assess the reliability of newly developed questionnaires measuring theoretical constructs believed to predict fruit and vegetable consumption among 6th-grade pupils.


METHODS
Participating pupils and parents completed questionnaires twice, 14 days apart.


METHODS
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.


RESULTS
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.


CONCLUSIONS
Sixth graders and their parents are able to provide reliable reports on theoretical determinants of the pupil's fruit and vegetable consumption.
