An introduction to the National Nursing Assistant Survey

This report provides an introduction and overview of the National Nursing Assistant Survey (NNAS),the first national probability survey of nursing assistants working in nursing homes. The NNAS was designed to provide national estimates and to allow for separate estimates to be calculated for nursing assistants by geographic location of the agency and for workers by tenure at the sampled facility. This report includes a description of relevant research that led to federal interest in sponsoring the NNAS, types of data collected, methodology, linkage between the NNAS and the 2004 National Nursing Home Survey (NNHS), advantages of combining establishment and worker surveys, and potential uses of the data.

The NNAS was conducted as a supplement to the 2004 National Nursing Home Survey. The design was a stratified, multistage probability survey. Nursing facilities were sampled and then nursing assistants were sampled within the facilities. Telephone interviews were conducted with nursing assistants using Computer-Assisted Telephone Interviews (CATI). The survey instrument consisted of sections on recruitment, training and licensure, job history, family life, management and supervision, client relations, organizational commitment and job satisfaction, workplace environment, work-related injuries, and demographics.

A total of 3,017 interviews were completed from September 2004 to February 2005. The overall response rate was 53.4 percent. A public-use data file has been released that contains the interview responses and sampling weights. The file also includes ownership, bed size, and geographic location of the facility where the nursing assistant was sampled. Estimates based on the sampling weights can be used to produce national estimates.
