Example of process to identify linking units and ICF-CY codes (Part I) and ‘visual ability’ themes & categories (Part II)
| Part I | Part II | ||||||
|---|---|---|---|---|---|---|---|
| Descriptive theme | Analytical theme | ||||||
| Measure | Item | Linking unita | ICF-CY codeb | Descriptive word for visual ability | Indicator of visual ability | Theme: Observable visual behaviour | Category of visual ability behaviour |
| CVI Q [16] | Manipulates an object rather than look at it (Item 40, Other senses domain) |
Use of other senses | d110 Watching d1201 Touchingc |
Look | Look at object Manipulate rather than look (other senses) |
Watches and/or visually interacts with objects Frequency of use of vision in activities |
Interactions Use of vision |
| FVQ [18] | Tracks an object/toy (Item 2) | Tracking | d110 Watching | Tracking | Tracks an object/toy | Follows | Abilities |
| Watches and/or visually interacts with objects | Interactions | ||||||
| PreViAs [24] | Is he/she able to look towards a sound source? (Item 3) | Looking toward a sound sourced | d110 Watching b2302 Localisation of a sound source |
Look | Looks toward sound source | Searches | Abilities |
| VSI [36] | Does your child reach for a large, bright, silent object? (Item 17) | Reaching | d4452 Reaching | n/a | |||
aLinking unit = What is the item about?; bOnly assessment items which have been linked to an ICF-CY ‘visual ability’ code of d110 Watching, d160 Focusing attention or d161 Directing attention are included in Part II; cThis is an example where the exact term in the ICF-CY does not match the construct as described in the measure i.e., linked to d1201 Touching and not d4402 Manipulating; dExample of an item where it was not easy to identify what the item was about e.g., is it about ‘Turning to look’?, ‘Hearing a sound’ or ‘Looking’
