Psychological interventions to enhance positive outcomes in adult cancer caregivers: A systematic review

This systematic review aims to examine the characteristics of psychological interventions that aim to enhance positive outcomes, such as wellbeing, post-traumatic growth, or hope in cancer caregivers. Studies published until December 2023 were searched on PubMed, Scopus, PsycINFO, WOS, PsycARTICLES and were included when examining interventions targeting positive outcomes with adult cancer caregivers. Of the 1424 articles retrieved through the databases, 16 studies were eligible for inclusion in this review, targeting 908 caregivers (70.2% female; Mage = 53.5). A narrative synthesis was used to describe the interventions, which were based on a variety of approaches such as psychoeducation, mindfulness, or Existential Behavioral Therapy, and reported positive gains for the positive outcomes. The results show few randomized controlled trials published to date, highlight the contrast between the focus shift towards these outcomes and the need for systematic testing of the interventions, to be able to inform evidence-based service delivery.
