Brief summary
In adolescents with congenital heart disease physical activity level is reduced which is why promotion to a more active lifestyle with an age-appropriate and modern intervention is needed. In healthy subjects digital health nudging was shown to increase physical activity. However, in adolescents with congenital heart disease such studies have not been conducted yet. In this RCT participants receive daily, short smartphone messages with the primary purpose to increase daily physical activity, which is monitored with a Garmin vivofit jr. wearable.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Objectively measured physical activity | 25 weeks | Physical activity is objectively assessed with the wrist worn wearable Garmin vivofit jr.. Daily physical activity is measured on the basis of active minutes in moderate-to-vigorous intensity. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Objectively measured daily step count | 25 weeks | Daily step count is objectively assessed with the wrist worn wearable Garmin vivofit jr.. |
| Activity-related self-efficacy | Baseline, after 12 weeks, after 24 weeks | Perceived self-efficacy in the context of physical activity is measured using the German version of the Physical Activity Self-Efficacy Scale. The scale consists of eight items, each of which is answered on a five-point Likert scale. |
| Health-related quality of life | Baseline, after 12 weeks, after 24 weeks | Health-related quality of life is self-assessed via the KINDL® questionnaire. The KINDL® is a generic instrument for assessing health-related quality of life in children and adolescents.
