Decolonising Outcome Measurement: A Systematic Review of Health and Wellbeing Measures for Māori

Abstract

The objective of the study is to conduct a systematic review and methodological quality appraisal on studies reporting the development of health and wellbeing outcome measures for Māori (Indigenous people of New Zealand), identify common features and processes, and critically appraise the measures using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN). Key databases were searched using key terms in May 2022 without date limiters. English or Māori language publications were included if they reported Māori health and wellbeing outcome measure development. Studies were then appraised using the COSMIN. Seven publications developed outcome measures and seven reported the validation of the measures. All studies were Inadequate when appraised using the COSMIN so measurement properties were not appraised. This study highlights the value of integrating Indigenous and western research methods to yield culturally relevant outcome measures, promoting equity in health and wellbeing assessment for Māori.
