A personalized digital lifestyle management application (\u201clevidex\u201d), designed to support people with MS (pwMS) in coping with their diagnosis and adopting healthier behaviors, was evaluated against an active psychoeducational control program (\u201cdexilev\u201d) in a randomized controlled trial (RCT; \u201cPOWER@MS1\u201d).<\/jats:p>\n <\/jats:sec>\n \n Objectives<\/jats:title>\n This study evaluates the POWER@MS1 trial, focusing on the processes and organizational aspects of the study. Specifically, it seeks to (1) identify the contextual factors that influence behavior change in pwMS and (2) assess how the intervention and study design were perceived by pwMS and involved health care professionals (HCPs; neurologists, study nurses, radiologists).<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n \n A mixed methods approach was applied. During the study period questionnaire data were collected from all trial participants (\n n<\/jats:italic>\n \u202f=\u202f234) and HCPs (\n n<\/jats:italic>\n \u202f=\u202f91) and were analyzed quantitatively. After the RCT ended, semi-structured interviews were conducted with 15 HCPs and 16 pwMS. Participants were selected according to the maximum variation sampling. Data was analyzed thematically.\n <\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n Quantitative trial data revealed that the levidex group significantly agreed more to behavioral changes after 3\u202fmonths [levidex (6.65); dexilev (5.23),\n p<\/jats:italic>\n \u202f&lt;\u202f0.001]. Improvements in diet, physical activity and stress management were reported. PwMS considered evidence-based information, meditation instructions and self-monitoring tools embedded in levidex as particularly helpful. In the interviews, they reported close monitoring through regular clinical visits as reassuring after MS diagnosis. A healthy lifestyle was considered an important component of MS treatment by both HCPs and pwMS. Both perceived levidex as a useful addition to standard care, but reported a need for additional personal consultation.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n Health behavior change was rated as an important component of MS treatment. A digital application was perceived to be beneficial for the facilitation of relevant behavior change.<\/jats:p>\n
