How Prescribed Music and Preferred Music Influence Sleep Quality in University Students.

Objective: The purpose of this study was to investigate the effect of listening to music on sleep quality in university students and to explore the influence of preferred music on this effect.

Methods: University students identified by the Pittsburgh Sleep Quality Index (PSQI) as 'poor' sleepers (global score > 5) were assigned to three groups (a prescribed music group, preferred music group, and no-music group). During the period of intervention, the prescribed music group and preferred music group listened to their assigned type of music at home every day at bedtime.
