title: Construct validity of the Sivik Psychosomaticism Test and test of operational style: correlations with four Minnesota Multiphasic Personality Inventory (MMPI) subscales.
abstract: To evaluate the construct validity (convergent and divergent) of the Sivik Psycho Somaticism test (SPS) and test of Operationality (OPER), Pearson correlation coefficients between SPS scales and subscales, OPER and Minnesota Multiphasic Personality Inventory (MMPI) subscales Hypochondria (Hs), Depression (D), Hysteria (Hy) and Alexithymia (Al) were calculated. Eighty-eight healthy individuals and 285 psychosomatic patients completed the SPS and OPER tests and MMPI; Hs, D, Hy and Al. The results show that most of the SPS subscales and OPER are significantly correlated to several MMPI subscales in both a normal and a psychosomatic population. The results are in concordance with the theoretical hypotheses and confirm the validity of the SPS and OPER constructs.
