[Which Digital Services do Psychosomatic Rehabilitation Patients Use During the Corona Pandemic and do Interrelations with Anxiety and Depressive Symptoms Exist?].

Objective: The COVID-19 pandemic requires numerous measures to protect against infection, such as contact reduction and adherence to hygiene and social distancing rules. The former leads to mental disorders (possibly requiring treatment) due to social isolation, the latter require adaptation in the implementation of medical therapies. With overall limited therapy capacities, the use of digital (health) applications can be of particular importance in the therapy of chronic and psychological diseases in particular. The present study investigates which health apps are being used by people with mental health problems.

Methods: 1,060 insured persons in preparation for psychosomatic rehabilitation measures were surveyed by means of an online questionnaire. Descriptive analyses, frequency analyses, and analyses of variance with post-hoc tests and correlation analyses were used for evaluation.

Results: Participants used on average three apps; the most common topics were "nutrition" (n=313), "self-diagnosis" (n=244) and "relaxation" (n=234). Female participants were more likely to use apps than male participants, and younger participants were more likely to use apps than older participants. Symptoms of anxiety were correlated to the use of digital applications, especially concerning heart rate and blood pressure monitoring, while depressive symptoms were not associated with a more frequent use of apps.

Discussion: Digital apps are being frequently used by people with mental health problems. Increasing acceptance of digital (health) apps has significant potential in the treatment of chronic mental illness in particular. The focus should be on individual applications with integration into the regular care process.

Conclusion: Increasing digitalization, also in the healthcare sector, can be used to ensure care, especially in times of contact restrictions and limited human resources.
