| Annotation | Most adults with Down's syndrome develop Alzheimer's dementia relatively early in their lives, but accurate clinical diagnosis remains difficult. The authors used qualitative methods to gather information from carers of people with Down's syndrome about the symptoms of dementia. They provided the items for the Dementia Screening Questionnaire for Individuals with Intellectual Disabilities (DSQIID) which was then tested for its psychometric properties. The DSQIID was administered to carers of 193 adults with Down's syndrome, 117 of whom were re-examined by clinicians who confirmed a diagnosis of dementia for 49 according to modified ICD-10 criteria. The authors established that a total score of 20 provides maximum sensitivity (0.92) and optimum specificity (0.97) for screening. The DSQIID has sound internal consistency for all its 53 items, and good test-retest and inter-rater reliability. The authors established a good construct validity by dividing the items into four factors. The DSQIID is therefore a valid and user-friendly observer-rated questionnaire for dementia in adults with Down's syndrome. (RH). |
