    We conducted this longitudinal study to evaluate the relationships of positive and negative affectivity (Affect Balance Scale) to sleep quality among civil servants. For this study we evaluated 827 civil servants of T city in Toyama prefecture in the springs of 2001 (Baseline) and 2004 with complete information in both phases of the study. Based on the median score at each phase, we divided Affect Balance Scale (ABS) scores into high and low groups. We conducted logistic regression analysis to determine the odds ratios (OR) of 3-yr follow-up sleep quality by baseline and follow-up ABS scores. After adjusting for baseline sleep quality scores, age, sex, employment, job strain, and exercise habits, participants who had high ABS scores were more likely (OR: 3.13, 95% confidence interval (CI): 1.78-5.53) to have better sleep quality than those with low ABS scores at both phases. In addition, participants with low ABS scores at baseline and high ABS scores 3 yr later had better sleep quality (OR: 1.81, 95%CI: 1.02-3.20) than those with low ABS scores at both phases. These findings substantiate the relationships of positive and negative affectivity to sleep quality. Improving the affect balance condition as well as maintaining good affect balance condition may be important determinants of sleep quality in civil servants.
