To test the relationship between stress and sleep and the mod- erating role of coping style, we used a repeated-measure analysis of variance based on the general linear model (GLM) analysis (SAS, 1990), with gender and age as control variables and EFC, PFC, and DE as three linear independent measures. All of the predictors and control variables were simultaneously entered into the model. The sleep measures on each testing period (low and high stress) were used as the dependent measures, with period as the independent repeating measure (with two levels for low- and high-stress measurement periods).
