AnnotationThe Cognitive Decline scale of the Psychogeriatric Assessment Scales (PAS) uses informant data to assess retrospectively change from earlier in life. Data from a 7-8 year longitudinal study were used to assess the validity of this scale against changes in cognitive performance and mortality of large sample groups of over 70s in Canberra and Queanbeyan, Australia. PAS data were collected on three occasions with gaps of 3.6 and 4.1 years between. Scores of 4+ on the first predicted mortality and further cognitive decline. Those with scores of 4+ on the third showed substantial deterioration over the previous 7-8 years. The Cognitive Decline Scale allows a valid retrospective assessment of change, and has predictive validity for subsequent cognitive deterioration and increased mortality. (RH).
