aType of assessment determines type of information to be linked: patient-oriented measure (self-report, caregiver report or health professional reported) or clinical assessment; bNumber of domain codes may equal more than the number linking units as some linking units were given two codes; cExamples of constructs linked to Body Functions: seeing functions (visual acuity, visual field, and the ability to sense light, form, shape and colour, and eye functions), mental functions (orientation, memory, response time, visual perception and discrimination, visuospatial perception, knowledge and application of knowledge, recognition and object permanence), hearing functions, and neuromuscular functions such as reflexes and eye-hand coordination; dActivities and Participation codes are expanded in Table 3; eEnvironmental factors include supports or barriers of adapted products including large print or glasses/contacts, light in the environment, or people providing support; fOther includes personal factors such as a child’s interest or mood, the use of compensatory strategies, and interventions such as patching; g Number of ‘visual ability’ constructs is total number of linking units coded to the visual ability codes (d110 Watching, d160 Focusing attention, d161 Directing attention) as % of the total linking units
