[Internet-based self-help for loneliness-a systematic review].

Abstract

Background: Recently, the phenomenon of loneliness has received increasing attention. Loneliness is widespread and can have adverse consequences for mental and physical health if prolonged. Internet-based interventions (IBIs) for self-help have proven to be effective for a variety of psychological disorders. Due to several specific aspects, IBIs are also a relevant option for loneliness. This systematic review aims to present the current research on self-help IBIs for reducing loneliness.

Methods: A systematic literature search was conducted in the databases Web of Science, PubMed, Scopus, PsycInfo, MedLine, PsycIndex, Cochrane Library and PsyArXiv between December 2023 and early January 2024. We included original German or English studies that addressed IBIs for self-help to reduce loneliness.

Results: In total, eight studies published between 2017 and 2024 were included in the qualitative analysis. All studies were conducted in high-income countries, included predominantly well-educated female adults and were mostly satisfactory regarding their internal validity.

Discussion: The results of this review suggest that self-help IBIs may be a promising option for alleviating loneliness. However, the work also points to the need for further research. Future studies should consider larger samples and people of different ages, genders and education levels in order to generalise the results of the present review.
