Psychotherapy in patients with long/post-COVID – A systematic review on the feasibility, acceptability, safety, and efficacy of available and emerging interventions

Abstract

Backgrounds

There is an urgent need for effective treatments for patients with long/post-COVID. Current recommendations for management favor a multimodal approach including psychotherapy and emphasize that interventions should also consider the mental health impact of living with long/post-COVID. This systematic review synthesizes psychotherapeutic interventions that currently target long/post-COVID complaints and summarizes data on the feasibility, acceptability, safety, and efficacy of psychotherapy for patients with long/post-COVID.

Methods

This systematic review was conducted according to the PRISMA statement. Studies were retrieved from three databases (PubMed, PsycInfo, Web of Science) and independently assessed by two raters. Studies investigating patients of any age suffering from long/post-COVID were included if the intervention involved psychotherapeutic treatment and changes in long/post-COVID symptoms were reported. The review has been pre-registered on PROSPERO.

Results

A total of 12 studies were included in the analysis. Of these, 10 were multimodal approaches with integrated psychotherapeutic interventions, and two were studies on stand-alone psychotherapy. The majority of studies were uncontrolled and demonstrate pre-post improvements in a range of long/post-COVID symptoms. Only one RCT could be identified, which supports the benefit of CBT for COVID-related fatigue. It was not possible to draw general conclusions regarding the efficacy of psychotherapy for long/post-COVID. However, data on feasibility, acceptability, and safety support the potential of psychotherapy as a treatment approach for long/post-COVID.

Conclusion

Future studies investigating the potential of psychotherapy approach for long/post-COVID which go beyond the pilot stage are needed to systematically assess feasibility, acceptability, safety, and efficacy in large-scale confirmatory trials.
