The aim of this study was to determine if low mood influenced the association between eating problem symptoms and self report sleeping quality in a large group of young women and men. A group of 381 female and male undergraduate students completed a set of self-report inventories in order to test a model developed for this study observing the association between eating problems, low mood, restricted dieting, weight and self-reported sleeping quality using a path analysis model. The model that best fit the data indicated that eating problem symptoms were associated with low mood and low mood was related to sleeping quality. There was also a direct association between eating problems and sleeping quality but this was reduced by the presence of low mood in the equation. There were no other direct relationships with sleeping quality but there was an association between low mood and low weight. There were also differences reported between men and women on sleeping quality suggesting that women in this sample reported more sleeping difficulties than men. In all this research demonstrates with a large non-clinical sample the links between eating problems, mood and sleeping difficulties.
