Maximizing worksite survey response rates through community organization strategies and multiple contacts.

BACKGROUND

Worksites are natural settings for health promotion. In many cases, the effectiveness of such interventions is appraised by surveying employees to assess worksite-wide changes in the targeted behavior. Little attention has been paid to increasing worksite survey response rates. One way is to utilize community organization strategies, which involve enlisting the individuals within a group to work together with researchers to affect the social environment.

METHODS

Community organization strategies and multiple contacts were used to obtain responses from employees in five worksites involved in a smoking cessation project. Employee Advisory Board members in each worksite reviewed, adapted, and revised the survey distribution method, the messages that accompanied the survey, and the survey content. Three major survey waves were undertaken: a worksite effort, a home mailing (in the pilot worksite only), and a telephone call to nonrespondents.

RESULTS

Response rates to a worksite-wide survey in one worksite the first year and four additional worksites the next year yielded 99.3% and 98.4% response rates, respectively. In the pilot worksite, 273 employees were eligible for the survey with 366 eligible employees in the four other worksites. Chi-square or analysis of variance computations were used, as appropriate, to test for differences in characteristics of respondents in the various data collection waves.

DISCUSSION

These results suggest that there may be merit in adapting such community organization intervention methods for research applications.
