I'm developing a new patient reported outcome measure to assess functional activity status among Indian patients with stroke. This scale intend to evaluate patients mobility,self care, domestic and social life domains. I'm facing difficulties in choosing a relevant measure to use as a criterion/concurrent measure for validating domestic and social domain items that are applicable in Indian setting. The existing and commonly used measures of participation are either too lengthy (LIFE-H,activity sort) or contents are not applicable to Indian patients. I would appreciate specific inputs on the methods too
