Exclusion criteria
Exclusion criteria: A) Treatment adherence is already sufficiently good, with little need for further improvement. (Defined as a proportion of days with >4 hours of CPAP use of 90% or higher, and an average daily usage time >=7 hours over the past 1 month.) B) No CPAP usage at all during the past 1 month (for example, due to business trips, caring for family members, or other social reasons resulting in an inability to use CPAP, and for whom improvement in adherence through this intervention is not expected).

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary outcome is the number of participants whose CPAP adherence improved, comparing before and after the intervention. CPAP adherence during the six months following the start of the intervention will be compared with adherence during the three months prior to obtaining consent. Improvement in adherence will be defined as meeting either of the following criteria: (1) The average daily usage time increases by 30 minutes or more, or (2) The average daily CPAP usage time increases, AND the proportion of days with CPAP usage of 4 hours or more per day increases by 10 percentage points or more. | — |
Secondary
| Measure | Time frame |
|---|---|
| In addition to the primary outcome, the following secondary outcomes were set: (1) Change in the proportion of days with CPAP usage of 4 hours or more per day, comparing the 3 months prior to obtaining consent and the 6 months following the intervention (2) Change in average daily CPAP usage time, comparing the 3 months prior to obtaining consent and the 6 months following the intervention (3) Change in the proportion of days with CPAP usage of 4 hours or more per day, comparing the month prior to obtaining consent and the 6 months following the intervention (4) Change in average daily CPAP usage time, comparing the month prior to obtaining consent and the 6 months following the intervention (5) Change in sleepiness, comparing the time of enrollment and 6 months after the intervention | — |
