"This Handbook deals briefly with certain concepts related to the design of psychometric instruments, with particular emphasis on those that apply to the construction and use of psychiatric rating scales. In addition to an elementary discussion of psychometric principles, the text includes descriptions of a representative grouping of rating scales currently used in a variety of clinical and research contexts. Selections were made after consultations with professionals in the field, many of whom are authors of rating scales, and after an intensive search of the literature pertaining to the use of psychiatric rating scales...In bringing together in one publication an account of leading rating sscales, we hope not only to assist the investigator in the selection of an appropriate instrument for his research, but also to acquaint him with those scales on which a substantial body of information exists...." (the preface)
This Handbook contains 19 rating scales and discussions about them. Worldcat finds no earlier editions (we dated this copy based on the Govt printing format in rear: 1966-222-014 which normally means it was printed in 1966). It must have found significant value in the community - the 1981 edition has 239 pages (more than five times the number of pages here).
After 1981 we don't find any other editions in Worldcat until a new title: "Handbook of clinical rating scales and assessment in psychiatry and mental health" appears in 2010, with 320 pages and sections on various disorders and their scales.
