Implementing the British Columbia Nutrition Survey: perspectives of interviewers and facilitators.

The British Columbia Nutrition Survey was the last of ten provincial nutrition surveys completed between 1988 and 1999. A qualitative process evaluation was conducted to identify strengths and weaknesses of British Columbia Nutrition Survey procedures, as perceived by 27 public health nurses and dietitians directly involved in data collection. Data for the process evaluation were collected through in-depth telephone interviews, during which interviewers and facilitators described their experiences working for the survey. Qualitative analysis of interview transcripts identified codes that were then organized into eight categories, including issues arising from interviewer and facilitator training, challenges in recruiting survey participants, reflections on safety for survey personnel and participants, facilitators' key role, the flexibility required to implement the protocol, and communication within the survey research team. Two final categories related to rewarding aspects of the job: insights affecting professional practice, and meeting survey participants and personnel. Evaluation findings show the importance of establishing open communication between research planners and those conducting surveys. This communication is needed to ensure that workers' needs are met, the quality of the study is maximized, and evaluations of study protocols include the perspectives of those directly involved in data collection.
