Most persons living with dementia (PLWD) experience insomnia symptoms including difficulty falling asleep or staying asleep.
• Music interventions show promise for addressing insomnia in PLWD, as musical memory often remains intact despite cognitive decline and can be personalized to individuals.
• The purpose of this study was to test the prototype
features of a mobile application “Calming Music Personalized for Sleep Enhancement in Persons Living with Dementia (CoMPoSER)”.

We piloted CoMPoSER using a sequential rapid-cycle prototyping approach for 7 days with 10 dyads of PLWD
and their caregivers. • At follow-up, we assessed usability (Post Study System
Usability Questionnaire, Likert Scale 1-5), feasibility (Feasibility of Intervention Measure, Likert Scale 1-5), and appropriateness (Intervention Appropriateness Measure, Likert Scale 1-6).
• Baseline and follow-up interviews were analyzed using a rapid qualitative analysis technique.
