Implementation research for 'evidence-based' guideline development by dietitians: a pilot study to test an instrument.

AIM: To improve the quality of dietetic care, dietitians in the University Medical Center Utrecht (UMCU) are encouraged to develop and implement 'evidence-based' guidelines. The aim of this pilot study was to develop and test a questionnaire for implementation research to monitor the process of developing and implementing these guidelines. METHODS: A questionnaire was developed and distributed to 15 dietitians, who have started developing an 'evidence-based' guideline. The questionnaire measures determinants of dietitians' behaviour and the presence of conditions facilitating the development of a guideline. Cronbach's alpha with a cut-off point of 0.7 was used to analyse the internal consistence between the items related to behavioural determinants. A panel of professionals such as a member of staff from the UMCU, a communication expert and project-managers ensured the completeness of the questionnaire. RESULTS: The internal consistency was high (alpha > 0.7) between the items related to the determinants of behaviour. The questionnaire gives a structured overview of factors affecting positively or negatively the process of guideline development. Although dietitians have a positive behaviour towards guideline development, they perceived barriers related to the presence of conditions to develop a guideline. CONCLUSION: We concluded that the applied questionnaire is appropriate for implementation research and has given a structured overview of factors that influence the development of dietetic guidelines by dietitians in the UMCU.

Correlates of toothbrushing in preschool children by their parents in four ethnic groups in The Netherlands.

A previous study among Amsterdam 5-year-old children showed that on average, the older the child at the onset of toothbrushing and the less frequent the toothbrushing, the more life time caries experience it had. The aim of the present study was to assess correlates of these two caries risk factors, in four ethnic groups. A further aim was to evaluate the putative role of correlates as intervening variables between ethnicity and caries risk factors. Questionnaire data were available from the Amsterdam study, in which a stratified sample of 103 Turkish, 258 Moroccan, 59 Dutch and 56 Surinamese parents were interviewed at home in their mother tongue. Results showed 69 per cent of the Turkish, 45 per cent of the Moroccan, 17 per cent of the Dutch and 11 per cent of the Surinamese parents had commenced brushing their child's teeth only after its second birthday or even never at all. Moreover, many parents had not brushed their child's teeth every day. Almost all potential correlates in six domains, namely parental habits, attitudes, evaluative beliefs, behavioural beliefs, perceived role of the child and that of the partner, were found to be related crudely to the risk factors. Large differences in score patterns on the correlates were observed between ethnic groups. Multiple logistic regression analyses showed substantial parts of the differences in risk factor scores between the Turkish group and a combined Dutch and Surinamese reference group could be attributed to the intervening role of the correlates, as could only minor parts of the difference in risk factor scores between the Moroccan group and the reference group.(ABSTRACT TRUNCATED AT 250 WORDS)
