The questionnaire comprised of three sections- the first section asked for general description like name, qualification, occupation, income, marital status, etc. Second section explored the person’s felt difficulties in the activities of daily living and the third section sought specific information on the AEDs needs for assistance in key life functions and about the awareness of these devices. The section on AED contained a list of devices under each category, followed by a set of questions. First, it asks whether there is a difficulty or problem with this category of task/activity. Then it asks if the respondent is aware of the potential AED listed under that category. If the respondent is aware and using the device, whether there is a difficulty in use. In case the respondent is aware but not presently using the device, whether he/she would like to use in future.
