Please explain to me what is a pre-clinical stage?'A pre-clinical stage of disability can be detected by adding question related to IADLs'  It means that the disability can be identified before it becomes medically necessary to treat it. And what is a board- and -care home?  It is a residential unit in which people have a room, their food and any assitance/care that may be needed And in this title:' surveys, invetories, diaries', does 'inventories' mean the questions used in the surveys and 'diaries' means the way we save the item responses?  There is not enough context. Please give more information. Thanks for your help
