The DICHAQ is a self-reported participant-oriented outcome measure, calculated as the mean of the following 8 category scores (range: 0 to 3): Dressing and Grooming, Arising, Eating, Walking, Hygiene, Reach, Grip, and Activities. The score of each category is calculated as the maximum of the scores for the questions within that category. If aids and devices and/or help from another person are used for a category, a lower category score is adjusted to 2 for that category. A participant must have scores for at least 6 categories in order to compute the DICHAQ score. Total score is derived as average of all categories: 0 (no disability) to 3 (complete disability).
