title: The effect of social class on psychiatric psychological evaluations in patients with pulmonary tuberculosis.
abstract: The present study is a methodological examination in which the social and psychic background factors of 100 tuberculous patients, aged 20 to 45 years, were explored using psychiatric interview and psychological tests (MMPI, Rorschach, and Wartegg). The purpose of the study was to analyse the effect of social background factors on the psychiatric and psychological examination. With the help of correlation coefficients and three-factor factor analysis, the variable indicating the social class of the subject could be proved to correlate significantly to the projective test variables (Rorschach, Wartegg). No such correlation between the social group variable and those obtained in the psychiatric interview or the MMPI test could be demonstrated. On the basis of the projective tests, subjects in the lower social classes were considered more disturbed. It can be supposed that the background factors characteristic of lower social classes would contribute to the unfamiliar test situation, causing reactions disturbing the test performance. This suggests that the mentioned tests should be used with caution in the evaluation of personality disturbances.
