Test profiles as a diagnostic aid: The Rorschach

Association of Rorschach and MMPI Psychosis Indicators and Schizophrenia Spectrum Diagnoses in a Russian Clinical Sample

“…For the MMPI, the mean T scores on Sc were 83.69 (SD = 22.24) for men in my sample with ICD-10 schizophrenia spectrum disorder (n = 42) and 76.66 (SD = 20.39, n = 42) for women using the Russian norms (Berezin et al, 1994). In Table 6, these values are compared to American T scores reported for the MMPI-2 (Ben-Porath, Butcher, & Graham, 1991) and for the original MMPI, all for inpatient samples with schizophrenia or related psychoses using the relevant American norms (Dahlstrom & Prange, 1960;Gough, 1956;Schmidt, 1956;Wauck, 1950). As shown on Table 6, there were effect size differences between these samples ranging from negligible to medium (Cohen's d ranged from 0.04 to 0.66), all in the direction of my sample appearing somewhat more disturbed than the other sample.…”

What do MMPI zero items really measure: An experimental investigation

“…These results along with related findings (6-8. 9,16) suggested that endorsement of zero items was more representative of attributes contributing to "normalcy" or L'improvement'l than of pathology. Because of the unknown nature of zero scores in a psychiatric population and because of some concern about the appropriateness of scoring these items for deviancy, the general purpose of this study was to investigate the distribution of zero scores in a psychiatric sample and the relationship of these scores to a response set designed to improve test scores.…”

Compulsiveness as a Determinant in Selected Cognitive‐Perceptual Performances1

“…The Minnesota Multiphasic Personality Inventory (hereinafter referred to as the MMPI) was used to measure the degree and existence of compulsiveness m the control group as well as the experimental group Following the work of Gough (9), Meehl (16), Schmidt (19), and Guthne (10) and the general trend to profile analysis of the MMPI, a clinically useful and frequently appearing profile for obsessive-compulsive neurotics was utilized Expenence has proved that a profile with a peak at Pt (T-score > 70), secondary peaks at Sc and D( T-score of at least 65), with a decline of Hs and Hy on either side of D, and a low Ma (T-score < 57) is the usual profile for the obsessive compulsive patient When a patient at the psychiatric clinic showed an MMPI profile m agreement with the above, the therapist made an appointment for him to see the experimenter…”
