Part 1. Improvement criteria in drug trials with neurotic patients

Abstract

SYNOPSISPublished drug trials with neurotic patients are surveyed and rating scales and other improvement criteria are tabulated and related to outcome. These findings are compared with the results of studies which were designed to evaluate the effectiveness of various improvement criteria. The principles of the construction of distress scales and the method of testing reliability and validity of scales which purport to measure changes are discussed.
