Erste Schritte zu Smartphone-basierten Sportinterventionen im Alltag?
Eine Pilotuntersuchung der Effekte einer Sportintervention auf die Alltagsstimmung depressiver Personen
Abstract
Zusammenfassung. Digitalisierung ermöglicht die vielversprechende Integration von Gesundheitsinterventionen in unseren Alltag, u.a. auf Smartphones, und bietet Chancen zur Implementierung von Bewegungsinterventionen, von denen auch insbesondere psychisch Erkrankte profitieren können. Allerdings ist die Kluft zwischen technisch bereits Umsetzbarem und Wissen um Wirkungen im Alltag groß. Beispielsweise wurde gezeigt, dass Sport generell Depressionssymptomen entgegenwirkt. Der spezifische Einfluss von Sportinterventionen auf die Alltags-Stimmung – einem der drei von Depressionen betroffenen Kernbereiche – ist jedoch unzureichend erforscht. Um diesen spezifischen Effekt zu untersuchen und den Weg zu evidenzbasierten Smartphoneinterventionen zu ebnen, statteten wir 15 depressive Personen jeweils drei Tage vor und nach einer zehnwöchigen Sportintervention mit Smartphone-Tagebüchern aus. Die Probanden beantworteten 83.6% aller Stimmungsabfragen. Signifikante Cross-Level-Interaktionen in Mehrebenen-Analysen bestätigten, dass Personen, die zu Interventionsbeginn weniger Sport trieben, größere Stimmungsverbesserungen nach der Intervention zeigten (Gute-Schlechte-Stimmung: b = 5.8; Ruhe-Unruhe: b = 5.3). Diese Pilotergebnisse sollen helfen, den vielversprechenden Weg zu evidenzbasierten sportpsychologischen Interventionen auf dem Smartphone zu ebnen.
Abstract. Technological progress offers the chance to incorporate health interventions into everyday life, for example, on smartphones, which may be beneficial for people with mental illness. However, there is a large gap between what is technically feasible and what is known about effects on everyday life. For example, exercise is known to reduce depression symptoms in general, but specific influences of exercise interventions on everyday life mood, a core issue of depression, have yet to be studied. Therefore, we equipped 15 participants with depression with smartphone diaries for 3 days both before and after a 10-week exercise intervention. The participants answered 83.6% of all queries. Significant cross-level interaction effects in multilevel analyses revealed that people who engaged less in exercise at the start of the intervention showed greater improvements in everyday life mood (valence: b = 5.8; calmness: b = 5.3). Our results may serve as a tiny kick-off paving the way for evidence-based physical activity interventions on smartphones.
