.— A multivariable‐multimethod analysis was performed on six professional clinical psychologists' ratings of 38 patients for the three variables, Intelligence, Ability to Establish Contact and Control of Affect and Impulses. The judges based their ratings of the patients performance on each of the three tests Rorschach, TAT, and Sentence Completion separately as well as on all tests together. The stability coefficients and the consensus among judges was rather high but decreased when the depth of interpretation of the response variable increased. The ratings showed both convergent and discriminant validity but the generality of the ratings was generally low. The results support the opinions held among clinicians, that tests give different kinds of information about individuals and that clinicians, to some extent, use the information from each test as a subvariable which is integrated into a more global variable.
