Abstract
Sleepiness can  be felt by everyone at time and interfere with ability of work. Like others, professional nurses often feel sleepy during on duty.  However, there is little known of sleepiness in Thai nurses.  Thus, the purposes of this study   were to analyze the sleepiness scores and factors predicted sleepiness in Thai nurses.    Two hundred and ninety-seven nurses working in a hospital were selected in the study.  Those were asked to fill the questionnaires of  Epworth Sleepiness Score, Quality of Sleep Scale, and   Fatique Scale. Epworth Sleepiness Score was a single dimension.  Quality of Sleep Scale was consisted of 3 components: sleep disturbance, sleep effectiveness, and sleep supplementation.  Fatique scale was consisted of 4 components : behavioral/severity, affective meaning, physical/mood and cognition. Those scales were test for content validity and internal reliability. The reliability with alpha chronbach of  Epworth Sleepiness Score, Quality of Sleep Scale, and   Fatique Scale  were .88, .82, and.95, respectively.  All data were analyzed by using mean standard deviation, t-test and stepwise regression.
            The major findings were as follows:
1.      The mean scores of sleepiness were 8.55 (Scores ranging from 0-24).
2.      Behavioral/severity, physical/mood,and cognition (subscales of Fatique) were positively related to sleepiness (r = .238, .301,  and .299 respectively)
3.      Sleep effectiveness (a subscale of Quality of Sleep Scale) was  negatively related to sleepiness (r = - .220).
4.      The predictors of sleepiness were physical/mood, sleep effectiveness, and Behavioral/severity.  Those accounted for 11.6% of variance.
