Reliability of the Aboriginal Children's Health and Well-Being Measure (ACHWM).
PURPOSE
The aim of this research was to evaluate the reliability of the Aboriginal Children's Health and Well-Being Measure© (ACHWM).


METHODS
Two cohorts of children from Wiikwemkoong Unceded Territory were recruited for this study. Each child completed the ACHWM independently on a computer tablet running a customized survey app. The data from the first and second cohorts were used to estimate the internal consistencies using Cronbach's alpha. A subgroup of the second cohort completed the survey twice, within the same day. The data from this subgroup was used to evaluate the test-retest reliability using a random effects Intra-class Correlation Coefficient (ICC).


RESULTS
There were 124 participants in the first cohort and 132 participants in the second cohort. The repeated measures subgroup was comprised of 29 participants from the second cohort. The internal consistency statistic (Cronbach's alpha) was 0.93 for the first and second cohorts. The test-retest reliability ICC was 0.94 (95% CI 0.86-0.97) for the ACHWM summary scores based on the repeated measures subgroup.


CONCLUSIONS
These results establish the internal consistency and the test-retest validity of the ACHWM. This important finding will enable Aboriginal communities to use this measure with confidence and promote the voices of their children in reporting their health. The ACHWM is an essential data gathering tool that enables evidence-based health care for Aboriginal communities.
