The purpose of the study was to investigate the perceived anxiety experienced by coronary care nurses working eight- and 12-hour work shifts. It was hypothesized that length of shift work affects the before- and after-shift anxiety for nurses working eight or 12-hour work shifts. Anxiety differences between the eight- and 12-hour work shifts were examined as well as differences between the before- and after-shift anxiety for each length of shift.Thirty-two (32) coronary care nurses from a general medical and surgical hospital in the Midwest volunteered to participate in the research. The sample consisted of all females (18 Registered Nurses, nine Licensed Practical Nurses, three charge nurses, a supervisory nurse, and a rehabilitation nurse). The nurses had voluntarily selected the eight- or 12-hour length of shift work and understood that they would be committed to work that shift for one year. Twelve nurses worked the eight-hour shift; 20 nurses chose the new 12-hour shift.The State Anxiety Inventory (SAI) was used to measure the nurses' before- and after-shift anxiety. Baseline data were collected from the nurses prior to the initiation of the 12-hour shift. The Box-Jenkins Time Series Analysis was used to analyze the daily before- and after-shift anxiety scores and to establish a forecasted trend for both the eight- and 12-hour shifts.The first finding was that the before-shift anxiety scores for the eight-hour workers declined, while the anxiety scores for the 12-hour workers increased, following the implementation of the 12-hour shift. The same trend was forecast for the after-shift anxiety scores. The eight-hour nurses' after-shift anxiety scores declined while the 12-hour nurses' anxiety scores increased. A transfer function was conducted for both the eight-hour and 12-hour before- and after-shift anxiety scores. No predictive trend could be established for the eight-hour anxiety scores; however, the 12-hour after-shift anxiety scores were found to be consistently higher than before-shift anxiety scores. / Department of Educational Psychology

The present study was designed to assess the role of response time on the Category Test of the Halstead-Reitan Neuropsychological Test Battery (HRNB). The intent was to define the underlying constructs of the Category Test more particularly, the speed of performance by examining response time to individual slides of the Category Test.Seventy-two normal adult volunteers were administered the complete HRNB. Average response times were computed for correct (CRT), incorrect (IRT), and total (TRT) scores on the Category Test. The efficacy of using response measures (CRT, IRT, and TRT) to predict Category performance was examined in the context of other HRNB variables that loaded factorially with the Category Test, more specifically: TPT-time, memory, and location, Trails B, WAIS-R Block Design, and WAIS-R Object Assembly.A step-wise multiple regression analysis was computed using the above HRNB and response time measures to predict Category error scores. Results from this analysis indicated that TPT-location, TRT, and IRT contributed significantly (p<.05) in the prediction of Category scores. Approximately 15% of the variability in Category scores was explained by a measure of spatial memory (TPT-location) and an additional 15% was accounted for by psycho-motor speed (TRT and IRT). The significant contribution of response time in defining the underlying construct of the Category Test was discussed in terms of possible implications for enhancing the neuropsychological significance of the Category Test.
