Four overarching themes were identified: (1) reasons to participate in the trial, (2) personal resources, (3) safety, and (4) experience of the randomization. The most frequent reason for participating in the trial was to support research and help others, but many also participated hoping to receive the intervention treatment. The study showed that a surplus of personal resources played an important role when the patients decided to participate in the trial. Differences were found between patients belonging to the intervention and the control group in relation to these themes. Finally, both groups experienced the extra examinations received during the trial as an additional source of safety.
