Design and Sample
long-term illness, impaired cognitive
The study utilized a qualitative design with an inductive approach and was conducted as part of a process evaluation within a randomized controlled trial evaluating the effects of tele-yoga (ClinicalTrials.gov Identifier: NCT03703609). This study used a single-blind methodology where the evaluator and analyst were blinded, and it followed a parallel 2-arm randomized controlled study format. The participants were allocated in a 1:1 ratio to either the intervention group, which received tele-yoga, or the control group. A total of 200 individuals with long-term illness were recruited so far in the randomised controlled trial from 4 hospitals in southern Sweden and subsequently randomized into 2 groups. The first group (n=100) participated in a tele-yoga intervention conducted at home over a period of 3 months. The second group (n=100) served as the control group and received individual exercise advice during the same timeframe. The participants were recruited from those who had been admitted to the departments of cardiology or intensive care in the past 3-36 months, with a minimum length of stay of 48 hours during their hospitalization. To meet the training requirements, the participants were included in the study when they were stable in their medical condition and aged over 18 years. Exclusion criteria were short life expectancy (<6 months), impaired cognitive ability, lack of ability to fill in forms, and inability to complete the tele-yoga intervention. In this qualitative study, we consecutively invited the 100 patients randomized to the intervention group at baseline before starting the tele-yoga intervention to participate in an interview.
