  • Statistical comparison was performed with a mixed ANOVA with group as a between-subject factor and moment as a within-subject factor. There were no significant interactions between group and moment for any of the subscales. For all of the negative subscales, there was a significant restorative effect of the night [F(1,21) = 16.6, P = 0.001 for tension; F(1,26) = 5.4, P = 0.029 for depression; F(1,21) = 5.1, P = 0.035 for anger; F(1,21) = 20.8, P < 0.001 for fatigue].
