Estimation of Response Bias in the NHES:95 Adult Education Survey. Working Paper Series.
Brick, Mike; Kim, Kwang; Nolin, Mary Jo; Collins, Mary
The National Household Education Survey (NHES) is a data collection system of the National Center for Education Statistics (NCES) designed to address a wide range of education-related issues. It is a telephone survey of the noninstitutionalized civilian population. In 1995, the NHES included a survey of adult education (AE). This report deals with response bias in the AE component of the NHES. To estimate response bias for the AE, an intensive reinterview was conducted with a sample of respondents and the responses to this reinterview were compared with the original values to estimate response bias. Interviewers were not chosen from the regular pool of NHES interviewers, but were people with previous experience in less structured interviews. An interview protocol was developed for the reinterview. Of 230 cases sampled for the bias study, 206 respondents completed intensive reinterviews. The estimated bias in the overall participation rate of adults was 24%, and the bias-corrected estimate is that 64% of adults participated in AE in 1995, a figure considerably larger than the 40% reported in the NHES:95. Under-reporting may have resulted from a lack of understanding related to the less formal forms of adult education. The under-reporting of participation for work-related and personal development courses was substantial. Consistency problems were identified for items dealing with barriers to participation in adult education, but the reinterview program did not lead to new ideas to cope with inconsistent reporting (the switching problem) in the NHES:95. The intensive reinterview methodology appeared to have good potential for detecting biases, and it appears that response bias can be estimated using this methodology.
