Surveying nurses: identifying strategies to improve participation.

While surveys of nurses are an important tool in health services and policy research, they are often characterized by low response rates. The authors conducted a systematic review of 22 published reports of efforts to improve response rates to nurse surveys. Two general strategies were explored in this literature: incentive and design-based approaches. Even small financial incentives were found to be effective in improving nurse survey participation. Token nonmonetary incentives, in contrast, were much less effective. In terms of design strategies, postal and telephone strategies have generally been more successful than have fax or web-based approaches, with evidence also supporting use of mixed-mode surveys in this population. In addition, use of first-class stamps on return envelopes as well as questionnaires personalized and endorsed by legitimizing professional associations were also more likely to be successful. Researchers should continue to implement evidence-based strategies in order to improve the survey response of nurses.
