Exploring the psychological construct of resilience in kidney transplantation: A scoping review

Abstract

Background

Extensive literature has highlighted the psychological burden experienced by kidney transplant recipients (KTRs) and its association with adverse outcomes. Psychological resilience can serve as a measure of baseline vulnerability, and low resilience is associated with poor mental health. We aimed to synthesize the existing literature that has explored the concept of resilience in kidney transplantation.

Methods

A scoping review was conducted due to the anticipated heterogeneity of the literature. Any empirical study that measured resilience using a validated tool in KTRs was included. Resilience could be a variable, a predictor, or an outcome. All study designs were considered with no time restrictions.

Results

Of the 4525 titles and abstracts screened, 14 were eligible for inclusion. Sample sizes ranged from 10 to 505 KTRs. One study exclusively focused on developing and validating a resilience scale while others used existing tools. Three studies compared resilience between different populations and the results were heterogeneous: similar resilience between KTRs and dialysis/pre-KT patients (n = 2) and another reporting better resilience in KTRs (n = 1). A decline in resilience scores after pediatric-adult transition (n = 1) and 3 months post-transplant (n = 1) was reported. In terms of outcomes, higher resilience was associated with medication adherence (n = 1), lower frailty (n = 2), and lower risk of psychopathology (n = 2). Two of the three included studies reported improvements in resilience scores with an exercise program and a resilience-enhancing program.

Conclusions

Our review highlights that resilience is an underused and poorly explored construct in KTRs. We recommend explorative and interventional work as resilience is measurable and modifiable.
