Repeated measures anova revealed a main effect of TIME (P < 0.0001) and an interaction between TIME and GROUPS (P < 0.0001). Post hoc tests with Bonferroni correction showed that music statistically significantly improved sleep quality (P < 0.0001). Sleep quality did not improve statistically significantly in the audiobook and the control group. Depressive symptoms decreased statistically significantly in the music group (P < 0.0001), but not in the group listening to audiobooks.
