This edition of the "interRAI Community Health (CHA) Assessment Form and User's Manual" is customized to contain country-specific examples for Canada, and it uses the English language that is native to Canada. The CHA instrument was developed in response to user requests for a modular instrument that could efficiently assess the well elderly individual and identify those persons who merit further assessment in order to prevent or stabilize early functional or health decline. The instrument comprises a brief basic assessment and four supplements: Functional (CHA-FS), Mental Health (CHA-MH), Assisted Living (CHA-AL), and Deafblind (CHA-Db). The target population is adults living in the community and a variety of residential care settings. About the Additional Materials This book (published in 2019) includes additional materials that were not part of the previous edition (published 2010). These additional materials begin with an Errata and Addenda document that lists changes, updates, or additions to the published CHA manual and assessment forms. Following the Errata and Addenda document are two revised assessment forms, in which the errata/addenda have been implemented: the CHA Assessment Form (version 9.1.4) and the CHA Functional Supplement (CHA-FS) Assessment Form (version 9.1.4). Please note that these two revised assessment forms - CHA 9.1.4 and CHA-FS 9.1.4 - are included here in addition to the original versions, CHA 9.1.3 and CHA-FS 9.1.1. All of the other CHA forms (CHA-MH, CHA-AL, and CHA-Db) are also included here, and have not been updated or revised
