Rasch Measurement Theory's contribution to the psychometric properties of a co-created measure of health and wellness for Indigenous children and youth.

Objectives: To determine how Rasch Measurement Theory (RMT) methods can be used to assess the psychometric properties of the Aaniish Naa Gegii: the Children's Health and Wellbeing Measure (ACHWM) and Qanuippit.

Study Design And Setting: Indigenous children aged 8-18 years, from five communities, completed the 62-item ACHWM. We applied RMT methods to ACHWM data from 401 children (mean age 13.

Improving Prediction of Risk of Admission to Long-Term Care or Mortality Among Home Care Users With IDD.

Background: Frailty is an established predictor of admission into long-term care (LTC) and mortality in the elderly population. Assessment of frailty among adults with intellectual and developmental disabilities (IDD) using a generic frailty marker may not be as predictive, as some lifelong disabilities associated with IDD may be interpreted as a sign of frailty. This study set out to determine if adding the Home Care-Intellectual and Developmental Disabilities Frailty Index (HC-IDD Frailty Index), developed for use in home care users with IDD, to a basic list of predictors (age, sex, rural status, and the Johns Hopkins Frailty Marker) increases the ability to predict admission to long-term care or death within one year.

Patterns of mortality among adults with intellectual and developmental disabilities in Ontario.

Objectives: To determine recent mortality rates among Ontarian adults with intellectual and developmental disabilities (IDDs) and investigate changes over time in contrast to the general population. To determine the most commonly reported underlying causes of death and explore related coding practices.

Methods: Using linked health administrative data, four cohorts of adults with IDD aged 25-99 living in Ontario were followed for 1 year (one cohort for each year between 2011 and 2014).
