A systematic review of Indigenous caregiver functioning and interventions

Purpose
There is a global increase in chronic, degenerative illnesses that require long-term intervention and support as a result of the aging population. The majority of support needs are met by informal family caregivers. While there have been three decades of research focusing on caregivers in general, the extent to which research has focused on Indigenous caregivers is unclear. Worldwide, Indigenous peoples face severe economic and health disadvantages that may make them even more vulnerable to the negative aspects of informal caregiving. The current systematic review aimed to synthesize the extant literature on Indigenous caregiver functioning and the interventions that are efficacious in alleviating Indigenous caregiver distress.

Methods
Systematic review Inclusion criteria were peer-reviewed quantitative studies examining Indigenous caregiver functioning or evaluating Indigenous caregiver interventions.

Results
1172 unique records were located in the final search undertaken; only 7 articles, representing 6 unique studies, met the full inclusion criteria. Most studies contained numerous methodological weaknesses that compromised the reliability and validity of findings. Available studies suggest poor health and high burden among Indigenous relative to non-Indigenous caregivers. However, high levels of positive aspects of caregiving were reported in one study. A single intervention study suggests that poor health outcomes among Indigenous caregivers can be alleviated, though the quality and focus of this study was sub-optimal.

Conclusions
Overall, there is very little quality evidence around Indigenous caregiver functioning. Future research in this area would benefit from greater adherence to the standards of research that contribute to a strong and reliable evidence base.
