Objectives 1(a): feasibility outcome measures
MAY, RECRUITMENT, RECRUITMENT

Recruitment rate: A target recruitment rate to demonstrate feasibility was defined as 30 plus participants between May and August 2019 (4.5 months), or seven people per month, similar to other feasibility studies [Retention rate: The target retention rate was at least 75–80% of participants completing six or more of the 10 sessions (including orientation and all-day session), for retention to be deemed successful. In addition, there was a follow-up at Week-13 (e.g., tablet and self-reported home diary collection). A withdrawal rate of 20% or less was deemed to be indicative of program feasibility based on other feasibility studies [(i) Adherence: An adherence rate was used for participants using tablets, and a true adherence rate was used for participants using tablets and CDs, thus capturing all program participants (those that chose CDs or computer tablets).(ii) Adherence rate (tablets only): The adherence rate was deemed adequate if (i) participants completed three logins per week or 39 logins (3 logins per week × 13-weeks) and (ii) formal practice for at least 1.5 hours (90 mins) per week or 19.5 hours (1.5 hours × 13-weeks; 1170 mins) duration of the study, beyond the 9-week intervention.(iii) True Adherence rate (tablets and CDs): Formal meditation home practice is setting aside time to carry out the guided meditation recordings. Informal meditation practice is bringing awareness within the flow of participants’ day-to-day activities at any time. As such, to capture both formal and informal practices, a true adherence rate was determined by both i.) attendance rate (attending ≥ 6 or more sessions) and ii.) self-reported home practice diary consisting of formal practice and informal practice totaling ≥ 19.5 hrs (or ≥ 1170 mins) during the 13-week study. True adherence also includes formal and informal meditation home practice (in minutes).Duration of home practice: Comparing both tablet data collection of formal home practice and self-reported diary home practice logs to determine level of accuracy.
