BACKGROUND Children with cerebral palsy have a primary motor disorder that may be accompanied by disturbances of sensation or perception that impact their ability to use vision. Many other factors may also influence how a child ‘uses their vision’, yet our understanding of how to optimise outcomes rarely includes a focus on visual abilities. For some children with cerebral palsy, visual ability may be a strength. To maximise a child’s ability to use vision we first need a method to quantify visual ability. This thesis describes the conceptualisation, development, and initial validation of a scale to describe ‘how vision is used’ by children with cerebral palsy.
METHODS Using a multi-phase mixed methods instrument project design, the first step was a systematic review to identify and appraise existing measures. This was followed by a study to map items from existing measures to the International Classification of Functioning, Disability and Health (ICF) framework using standard linking methodology. After confirming the need for a new measurement tool, the second phase of this research involved an international online survey of key stakeholders; the construction of items and a rating scale; and pre-testing with cognitive interviews. The third phase explored the psychometric properties of the tool in initial field testing.
CONCLUSION MEVU is a new instrument to describe the use of basic visual abilities that has potential to support early intervention planning for children with (or at high risk of) cerebral palsy.
