The VQoL_Child and VQoL_Young Person are self-report questionnaires developed to assess vision-related quality of life (VQoL) of children and young people aged 8-17 years with visual impairment or blindness, and may be used as complementary adjuncts to our functional vision instrument versions (the FVQ_Child and FVQ_Young Person).
The VQoL_Child and VQoL_Young Person are intended for use by healthcare professionals and related specialists with children and young people aged 8 up to 18 years.
The VQoL_Child contains 20 items.
The VQoL_Young Person contains 22 items.
Both instrument versions use a 4-point response structure with age-appropriate instructions and question stems. The two instrument versions contain a common ‘core’ set of items relevant to all children and young people within the age-range of 8 up to 18 years, as well as age-specific items.
Summary scores from the VQoL_Child and VQoL_Young Person can be derived and transformed into measurement-scaled scores so that summary scores across different age groups can be compared.
Previous instrument versions:
The VQoL_Child and VQoL_Young Person are age-appropriate extensions of the original VQoL_CYP, which was designed for use with children and young people aged 10-15 years. The new age-appropriate versions replace the original VQoL_CYP, broadening the age-range of children and young people to whom the instrument is applicable. Both new versions are psychometrically robust, valid and reliable for capturing VQoL of children and young people within the specific age-groups.
Publications reporting the development of the new VQoL extensions are in progress. Papers reporting the development of the original VQoL_CYP are included in the References section.
What the instrument includes:
Both the VQoL_Child and VQoL_Young Person include:
The user manual contains a description of VQoL, a brief background to the VQoL_Child and VQoL_Young Person, administration guidelines, scoring instructions (including how to transform summary scores into comparable measurement-scaled scores) and relevant references.
Each instrument booklet contains a title page, instructions, prompts, question stems, items, and response options. It is important that all these elements are presented to children and young people using the instrument booklets. The instrument booklets containing the VQoL_Child and VQoL_Young Person differ in length and content.
Development of the original VQoL_CYP (for 10-15 year olds) was supported by The Guide Dogs for the Blind Association (Grant: OR2006-03b). Development of the new, age-appropriate extensions of the VQoL_CYP was supported by Fight for Sight (Grant: 1322).
