Table 1 Face to face session procedures

From: Effect of personal activity intelligence (PAI) monitoring in the maintenance phase of cardiac rehabilitation: a mixed methods evaluation

Session 1 individual face to face

Before intervention

Session 2 face to face

At 3 weeks

Session 3 face to face

At 6 weeks

• Participant informed consent form completed and signed

• Issued WPAM device

• Register participant with PAI Health (age, sex, weight, height, resting heart rate, maximal heart rate calculated using formula from PAI Health App [211–0.64xage]) **

• Participants download the test-flight PAI research APP onto their smartphone which was used to blind subjects to the data

• Instructed on daily syncing procedures, cleaning procedures (wiping to avoid grime and sweat interfering with accuracy of heart rate recording), charging procedures, and correct placement (2–3 fingers above the distal radius and ulna for the wristwatch: or two fingers below the deltoid muscle when using the arm strap)

• Education on switching between all day and workout mode on device and to maintain usual activity level

• Euro Quality of Life -5 Dimension-5 Level Health Questionnaire: English version for Australia (2009) completed

**For participants on beta blockers or calcium channel blocker medication, 15 beats per minute was subtracted from the calculated maximum heart rate; or the maximum achieved heart rate on an exercise stress test was used

• Blinded App removed and un-blinded App installed on smartphone

• Education about PAI given (verbal and written (handout) and three-minute video shown)

• Explanations given that PAI is based on heart rate responses to exercise, and that higher intensity exercise would result in greater accumulation of PAI points

• Educated on current research surrounding PAI, including the health benefits of maintaining 100 PAI

• Participants who accrued under 10 PAI during blinding were encouraged to aim for 50 PAI initially to avoid unrealistic goal setting and disappointment in not achieving 100 PAI

• Education about how to interpret the PAI APP, where to find the PAI score, seven-day bar graph, heart rate information and how to continue to sync the device was provided

• Euro Quality of Life -5 Dimension-5 Level Health Questionnaire: English version for Australia (2009) repeated

• Audiotaped interview (either individually or in pairs)

• Otter (speech to text software) used

• Questions pertained to their experiences and opinions during the trial and projected thoughts for the future
