Design outcomes

Primary

Measure	Time frame
Total number of blood pressure (BP) measurement opportunities for 14 days	—

Secondary

Measure	Time frame
Number of days that BP can be measured in the morning or night as instructed Number of days that BP can be measured as instructed, two occasions per day, at least twice per occasion Mean number of occasions for BP measurement per day Mean number of BP measurements per occasion Number and situation of occasions for measurements at times not instructed (e.g., before and after meals, before and after baths) Number of days that BP is not measured Subgroup analyses about days, occasions and times of BP measurement (sex, age, personality traits, stages of change in the transtheoretical model, level of health literacy, the value of BP, and the presence of antihypertensive medication) Changes in consciousness in BP control Changes in the number of occasions of BP measurement over time	—
