Abstract:

Objective:

To describe the development and reproducibility of a self-report instrument, for use with children in years 4-6, to identify sources of food eaten during the day, and type and frequency of food purchases at school. Design:

Tool development stages included formulation of content and format, expert review, piloting and a test-retest study. Subjects/setting:

The pilot study included school students (n = 20) in years 4 and 5 (seven girls, mean age 9.7 ± 0.7 years) attending an Australian public primary school. The test-retest study was performed in a large metropolitan public primary school (n = 245 children, 52% female, mean age 10.7 ± 0.91 years) including children from years 4 (n = 88), 5 (n = 84) and 6 (n = 73). Statistical analysis:

A Kappa statistic was used to assess level of agreement between the two time periods separated by 1 week. The results were analysed using SAS version 8.2 with each question compared at time 1 and 2. Results:

The mean kappa was 0.529 using pairings from 17 questions. Values ranged from 0.18 to 0.71 (CI 0.46-0.60). Conclusions and applications:

The School Eating Habits and Lifestyle Survey has been developed and pilot-tested in primary school-aged children and shown to have moderate stability over time. The results show that each phase of development, particularly those spent in consultation and testing, led to progressive improvement of this instrument. This process improved the quality of information produced and gave insights to self-report of dietary intake and behaviours among children.
