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

J Hum Nutr Diet. 2002 Aug;15(4):243-54. doi: 10.1046/j.1365-277x.2002.00368.x.


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.
