Design outcomes

Primary

Measure	Time frame
Assessment of eHealth literacy using the GR-eHEALS (revised German version of the eHealth Literacy Scale), consisting of eight items on a five-point Likert scale, measured before the intervention (T0), after the intervention ended (T1b), 1 month after the intervention ended (T2), and 3 months after the intervention ended (T3).	—

Secondary

Measure	Time frame
Assessment of health-related quality of life using the World Health Organization Quality of Life-BREF (WHOQOL-BREF), measured before the intervention (T0), after the intervention ended (T1b), 1 month after the intervention ended (T2), and 3 months after the intervention ended (T3). Assessment of changes in self-directed health behaviors (physical activity, diet, smoking behavior, alcohol consumption, self-management) using self-generated items on diet, physical activity, and smoking behavior; assessment of alcohol consumption using two items from the Alcohol Use Disorders Identification Test (AUDIT); and assessment of self-management using the Appraisal of Self-Care Agency Scale-Revised (ASAS-R), measured before the intervention (T0), after the intervention ended (T1b), 1 month after the end of the intervention (T2), and 3 months after the end of the intervention (T3). Measurement of changes in self-efficacy expectations using self-efficacy scales, assessed before the intervention (T0), after the intervention (T1b), 1 month after the intervention (T2), and 3 months after the intervention (T3). Measurement of changes in general and disease-specific health and well-being using self-generated items assessing patients’ self-perception regarding their physical and mental health, general quality of life, and emotional distress. To assess disease-specific health status, self-generated items regarding physical performance, pain perception, medical interventions, and current symptoms are collected, specifically before the intervention (T0), after the intervention (T1b), 1 month after the intervention (T2), and 3 months after the intervention (T3). Assessment of the usability of the mHealth intervention using the System Usability Scale (SUS), measured after completion of the intervention (T1b). Assessment of satisfaction with the mHealth intervention using the Client Satisfaction Questionnaire (CSQ-I), adapted for internet-based interventions, measured after complet	—
