INTRAFAMILIAL TRANSMISSION OF RHEUMATOID ARTHRITIS .2. AN INTERVIEW MEASURE OF RHEUMATOID ARTHRITIS

Our conclusion is that we have a very usable instrument in the 4-point RA measure, and that if our assumptions are correct, the associations to be presented in subsequent papers are just as true as if the respondents had been examined by a physician equipped with X-ray and laboratory facilities. In some senses this is an affirmation of the medical dictum that the history is by all odds the most important part of a medical evaluation. © 1969.
