Primary Outcome Measures

Name	Time	Method
ow disease activity or remission, categorized according to disease-specific instruments: Rheumatoid Arthritis Disease Activity Index (RADAI) for rheumatoid arthritis, Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) for axial spondyloarthritis and Disease Activity Index in Psoriatic Arthritis (DAPSA) for PsoA at baseline and 12 weeks.

Secondary Outcome Measures

Name	Time	Method
1. Adherence to a healthy Mediterranean diet measured using the Mediterranean Diet Adherence Screener (MEDAS) at weeks 0 and 12<br>2. Health-related quality of life measured with the Short-Form Health Survey (SF-36) at weeks 0 and 12<br>3. Weight (in kg) measured using a scale at weeks 0 and 12<br>4. Self-estimated time doing sports per week (in h) measured using a questionnaire via mobile phone application at weeks 0 and 12<br>5. Exercise per week measured using BSA (Bewegungs- und Sportaktivität Fragebogen = Movement and sports activity questionnaire) via mobile phone application at weeks 0 and 12<br>6. Mental health status measured using the Patient Health Questionnaire 5 (PHQ-5) questionnaire via mobile phone application at weeks 0 and 12<br>7. Rheumatoid arthritis disease activity measured using the compound Disease Activity Score-28 (DAS-28) during patient visit in a subgroup of rheumatoid arthritis (RA) patients at weeks 0 and 12
