What To Ask In A Self-Administered Dietary Assessment Website: The Role Of Professional Judgement, Y. C. Probst, Linda C. Tapsell
L. C. Tapsell
Background: Professional judgement is a key component of questionnaire development, subjective in nature and rarely reported in this context. It is required in dietary questionnaires to delimit the size whilst retaining quality of the data. Objectives: To describe the nature and extent of professional judgement involved in developing a food database to include in a web-based self-administered dietary assessment. Methods & materials: Professional judgement was applied in tandem with a stepwise statistical analysis of hierarchically reported foods in the Australian National Nutrition Survey (NNS95). Statistical analyses determined foods commonly consumed and eaten together and three different forms of cluster analysis …

Using a context-based case-control trial, 41 adults with type 2 diabetes mellitus were randomized into four groups to complete dietary assessments (computerized or interviewer administered) at 0, 2 and 8 weeks and food records at 0 and 2 weeks. Repeatability of reported energy, total fat, saturated, polyunsaturated and monounsaturated fatty acids between the computerized and interviewer administered methods were assessed using repeated measures ANOVA. Paired t-tests and Pearson's correlations determined relative validity of the assessments.

The objective of this paper was to determine relationships between patient age and BMI and use of a self-administered dietary assessment website in the primary healthcare setting. Chi- square and ordinal regression models were used to determine the relationships between age and BMI and computer experience, ownership, and usage from 188 patients using a self-administered dietary assessment website over 12 months. One hundred and twenty-five (66.5%) female and 63 (33.5%) male patients used the website. A total of 72.9% were overweight (BMI425 kg/m2). Advanced/intermediate computer users were 17.1 times more likely to own a computer than beginners or patients who …
