Objectives. The purpose of this study is to examine data from the Center for Epidemiological Studies Depression Scale, administered recently as part of the set of National Longitudinal Surveys sponsored by the Bureau of Labor Statistics, to showcase a public health component of the surveys.

Methods. The NLS of Mature Women (1989 and 1995), of Young Women (1993 and 1995), and Youth (NLSY, 1992 and 1994) provide data for all 20 items of the CESD in the earlier surveys and for 7 CESD items in the later surveys. Analyses of internal consistency (coefficient alpha) and of factor structure (principal components) are conducted separately for blacks and non-blacks using data from the earlier surveys. Items from the later surveys are correlated with items from the earlier surveys to examine the integrity of items over time.

Results. The CESD showed internal consistency ranging from .75 for non-blacks to .78 for blacks. The three factors that resulted are consistent with those that have been reported in the past, for both blacks and non-blacks, with the exception that no apparent distinction between the depressed affect and enervation factors emerged for either group. Females reported higher frequencies of depression than did males (youth cohort); blacks reported higher frequencies of depression than did non-blacks.

Conclusions. The NLS offers researchers an opportunity to study certain public health issues in this case the CESD, using large panels of Americans over time.
