The COOP Charts, analogous to Snellen Charts, were pretested in two practices on adult patients (<em>N</em> = 117) to test feasibility, clinical utility, and validity. Patients completed questionnaires containing validated health status scales and sociodemographic variables. Practice staff filled out forms indicating COOP Chart scores and clinical data. We held debriefing interviews with staff who administered the Charts, The results indicate the Charts take 1–2 minutes to administer, are easy to use, and produce important clinical data. The patterns of correlations between the Charts and validity indicator variables provide evidence for both convergent and discriminant validity. We conclude that new measures are needed to assess function in a busy office practice and that the COOP Chart system represents one promising strategy.</p></div>","PeriodicalId":15427,"journal":{"name":"Journal of chronic diseases","volume":"40 ","pages":"Pages 55S-63S"},"PeriodicalIF":0.0,"publicationDate":"1987-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S0021-9681(87)80033-4","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14719370","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Quantitative models that express age-specific mortality rates as functions of the exposure pattern and that allow such extrapolations to be made are presented. The uncertainty inherently associated with those extrapolations is discussed and is found to be exacerbated by small data sets and inadequate data availability.
