Abstract:A total of twenty-one participants completed the three-month study designed to assess the functionality of improving individual sleep habits with Actigraph Performance Feedback. There were eleven participants in the feedback group and ten participants in the non-feedback group. Each of these individuals completed three surveys. The first survey was administered on June 17th 2002, the second on July 14th 2002, and the third survey on August 28th 2002. Participants wore the non-feedback actigraphs for a 30 day base-line period followed by a 30 day period where half of the participants wore a feedback actigraph and half continued to wear the non-performance feedback actigraph.
Results indicate that study participants in the experimental group found the performance actigraph to be a useful tool for fatigue management. While there were not statistically significant differences between the feedback and non-feedback actigraph participants on indices assessing stress, fatigue, job satisfaction, anxiety, or quality of life, significant differences were found between the two groups on questions assessing the usefulness of the actigraph. Specifically, the most robust finding indicated that the performance sleep watch helped participants in the experimental group monitor their fatigue levels.
