Signals for effectiveness of the intervention
With regard to the effectiveness of our intervention, the pilot trial with 41 participants showed lower physical HRQOL (primary outcome) in the intervention group compared to the control group (mean 34.3 vs. 39.3). However, the mental HRQOL of the participants in the intervention group (mean 49.0) was higher than that of the control group (mean 44.4). It can be hypothesised that the intervention had a greater impact on the participants’ mental health than on their physical health. This is in line with previous findings from the PRacTICaL study [
