Feasibility of a Group Version of the Lifestyle-Integrated Functional Exercise Program

In a randomised noninferiority trial, it is investigated whether a group version of the Lifestyle-integrated Functional Exercise program (gLiFE) is non-inferior to the individually delivered LiFE in terms of feasibility and effectiveness. While effectiveness evaluation is ongoing, feasibility results are already available. Participants (>70 years; confirmed fall risk) were randomized in either LiFE or gLiFE and participated in the same strength and balance exercises, however, based on different approaches of delivery. LiFE participants received seven home visits; gLiFE was delivered in seven group sessions. Feasibility was defined as willingness to participate, adherence to group/home visits, and drop-outs. Predictors for intention to participate were calculated using regression. N=310 participants were randomized to LiFE (n=156) or gLiFE (n=154). n=51 (16%) of the participants dropped out after baseline. Attendance analyses showed that when excluding drop-outs, 100% (iLiFE) and 88% (gLiFE) took part in at least 5 of the 7 meetings. Self-efficacy and outcome expectancies, but not risk perception, were predictors of the intention to participate (F(3,193)=24.84, p
