Methods
HL
A randomized 2 × 3 repeated measures design was used. Survey measurements were taken at three-time points, baseline, at 8 weeks (after the 8-week coaching intervention), and at 20 weeks (after a 12-week no-treatment phase to determine the sustainability of outcomes). We employed a randomization sequence using Excel 2007 (Microsoft, Redmond, WA, USA) with a 1:1 allocation using random block sizes of 2 and 4 by a blinded team member (statistician) to randomize participants to either the Healthy Lifetime (HL) coaching intervention or the usual care group. The study was registered with CT.gov on 09/23/2021 (record NCT05070923) and was approved by the Institutional Review Board (IRB).
