Data Linkage: Canadian and Australian Perspectives on a Valuable Methodology for Intellectual and Developmental Disability Research

Building data linkage capabilities, and how linked databases can be used to identify persons with IDD and used for population-based research

Development and initial validation of the Communication Inventory Disability – Observer Reported (CID-OR): a measure of communication in CDKL5 deficiency disorder

CDKL5 Deficiency Disorder (CDD) is a rare neurodevelopmental disorder characterised by early onset seizures combined with complex healthcare needs and developmental impairment that influence functional domains including communication. Communication is a high priority domain for families but currently used measures demonstrate floor effects.

Beyond Seizures as an Outcome Measure: A Global Severity Scoring System for CDKL5 Deficiency Disorder

CDKL5 deficiency disorder (CDD) is a rare developmental and epileptic encephalopathy (DEE) associated with multiple impairments and comorbidities. Outcome measures for disease-modifying clinical trials for DEEs should measurably capture a spectrum of caregiver priorities and be externally validated.

Content Validation of the Communication Inventory Disability–Observer Reported CID-OR

CDKL5 deficiency disorder is a rare and severe developmental and epileptic encephalopathy that has profound effects on communication. It is essential that communication be measured accurately for upcoming gene therapy trials. The Communication Inventory Disability-Observer Reported was developed from a framework of communication derived from parent/caregiver interview data in consultation with disability and communication experts, and after reviewing concepts in existing measures.

Hospitalizations Following Complex Hip Surgery in Children with Intellectual Disability: A Self-Controlled Case Series Analysis

To evaluate the associations between complex hip surgery and subsequent hospitalizations in children with intellectual disability, including a subset of children with cerebral palsy.

Psychometric evaluation of clinician- and caregiver-reported clinical severity assessments for individuals with CDKL5 deficiency disorder

The CDKL5 Clinical Severity Assessment is a comprehensive, content-validated measurement tool capturing the diverse challenges of cyclin-dependent kinase-like 5 deficiency disorder, a genetically caused developmental epileptic encephalopathy. The CCSA is divided into clinician-reported and caregiver-reported assessments. The aim of this study was to evaluate the factor structure of these measures through confirmatory factor analysis and evaluate their validity and reliability.

Modifiable child and caregiver factors that influence community participation among children with Down syndrome

To investigate modifiable child and caregiver factors influencing community participation among children with Down syndrome.

The effect of functioning on Quality of Life Inventory-Disability measured quality of life is not mediated or moderated by parental psychological distress

The measurement of quality of life (QOL) in children with intellectual disability often relies upon proxy report via caregivers. The current study investigated whether caregiver psychological distress mediates or moderates the effects of impairment on their ratings of QOL in children with intellectual disability.

Longitudinal bone mineral content and density in Rett syndrome and their contributing factors

Bone mass and density are low in females with Rett syndrome.

Twenty years of surveillance in Rett syndrome: what does this tell us?

This study aimed to describe overall survival and adult health in those with Rett syndrome.
