The Change in Cognition with Age Questionnaire (CICAQ) was developed to identify symptoms of cognitive decline. Initial items were developed by identifying symptoms of early/mild dementia from a literature review, survey of experts in the field and a chart review of Prince of Wales Memory Clinic patients. CICAQ items were pilot tested on subjects with cognitive impairment no dementia (CIND) and their informants. Self-rated CICAQ scores did not differ between those with or without CIND. Informant ratings showed a difference, with CIND subjects rated as having a greater change in functioning.
The CICAQ was administered as part of the Sydney Memory and Ageing Study (MAS) as an informant rated scale. The purpose of the proposed study is to develop and validate the CICAQ scale. Scale development will involve identifying items relevant for inclusion in different versions of the scale (10-20 items). Scales will be compared against cognitive decline and an optimal scale length and cut-off identified. Scale validation will involve assessing how well the scale predicts cognitive decline and any potential sources of bias (e.g., age, education).
