ABSTRACT. Background. The Functional Independence Measure (WeeFIM) for children is a simple-toadminister scale for assessing independence across 3 domains in American children. WeeFIM was based on a conceptual framework by the World Health Organization (1980) of pathology, impairment, disability and handicap, and the "burden of care." WeeFIM is useful in assessing functional independence in children aged 6 months to 7 years. It can be used for children with developmental disabilities aged 6 months to 21 years. Normative WeeFIM data had been validated for American children. Because of cultural and environmental differences among countries, normative data for the Chinese population are needed. With a normative database, the progression of independence at home and in the community can be evaluated.WeeFIM is an 18-item, 7-level ordinal scale instrument that measures a child's consistent performance in essential daily functional skills. Three main domains (selfcare, mobility, and cognition) are assessed by interviewing or by observing a child's performance of a task to criterion standards. WeeFIM is categorized into 2 main functional streams: "Dependent" (ie, requires helper: scores 1-5) and "Independent" (ie, requires no helper: scores 6 -7). Scores 1 (total assistance) and 2 (maximal assistance) belonged to the "Complete Dependence" category. Scores 3 (moderate assistance), 4 (minimal contact assistance), and 5 (supervision or set-up) belonged to the "Modified Dependence" category. Scores 6 (modified independence) and 7 (complete independence) belonged to the "Independent" category. The WeeFIM is a 7-level criterion-specific ordinal scale. Level 7 requires no assistance for the child and the child completes the task independently without requiring a device. During the task, there is no concern about safety or taking an inordinate amount of time. Level 6 reflects modified independence and includes use of an assistive device or not completing the task in a timely or safe manner.Objective. To examine the utility of the WeeFIM in Chinese children and to create a normative WeeFIM profile suitable for Chinese children.Method. Direct interviews were conducted for 445 normal Chinese children, aged 6 months to 7 years, in the community.Results. 1. WeeFIM total score and 3 domains subscores versus age. The total WeeFIM scores increased progressively with age, reaching a plateau at 72 months.There was a progressive increase in subscores of selfcare, mobility, and cognition independence between 6 to 62 months, especially between 6 to 45 months. Similarly, the WeeFIM self-care subscores increased progressively with age, reaching a plateau at around 72 months. The WeeFIM mobility subscores increased progressively with age, reaching a plateau at around 54 months. The WeeFIM cognition subscores increased progressively with age, reaching a later plateau at around 80 months.2. WeeFIM subtotal scores versus age. The total WeeFIM score and 3 domain subscores correlated significantly with age. We further classified the 18 items into 3 ...
