| Annotation | An Instrumental Activities of Daily Living Scale for elderly people (IADL-E) for use in conjunction with cognitive screening tests for dementia in an educationally and socioculturally heterogeneous population was developed and validated. 11 IADL items were selected and weighted for major factors causing heterogeneity in the population: gender, education, social (rural/urban), degree of disability (scored from 0 to 2) and causative impairment (cognitive and/or physical). From this, a composite index of cognitive (CDI) or physical (PDI) disability was derived. Validation was performed retrospectively on 240 subjects in Kerala, India: 155 without and 105 with dementia by DSM-IV. The IADL-E had a high internal consistency. A cutoff score of 16 on CDI provided a sensitivity of 0.91, specificity of 0.99 and positive predictive value of 0.76. IADL-E correlated highly with clinical (DSM-IV), functional (CDR) and cognitive (Mini-Mental State Examination, MMSE) diagnoses. It showed good responsiveness, with the change on CDI over a median of 23 months correlating significantly with that on MMSE. Individual items had good inter-rater and test-retest reliability. The IADL-E is therefore a reliable, sensitive and responsive scale of functional abilities, useful in dementia screening in a socioculturally heterogeneous population. (RH). |
