The prevalence of epilepsy among children in the third grade in Multnomah County, Oregon, was investigated by use of a questionnaire similar tothat used by Rose et al. (1973). Of the 7,039 potential respondents, 5,317 (75.5%) responded to the questionnaire. A stratified random sample of 161 children was drawn from the respondents, and of these 129 (80%) underwent physical and EEG examinations. This replication of the study by Rose et al. (1973) yielded prevalence estimates which were somewhat lower than those reported by Rose et al. for Washington County, Maryland. Our findings suggest that the questionnaire method of estimating the prevalence of epilepsy has promise; further investigation of the method is in progress.
This study of a paper products factory was designed to provide objective data for the hypothesis that certain classes of industrial work cause alienation, using absenteeism as an index of dissatisfaction. A questionnaire was developed involving 38 distinctive features of man-machine interaction that characterized 40 different job-stations, involving a labor force of 230 male workers. Absentee records for a set of 6,000 man-work wks. provided the basis for the computation of absentee rates for each job station. Of the 40 job stations, those that embodied conditions where employees (a) set their own pace and/or (6) where they could adjust or correct the machine had less absenteeism associated with them (findings significant at .05 level of confidence, Mann-Whitney V Test).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
