Narcotic addicts comprising 2 diagnostic groups as defined by MMPI profile types (49′ sociopathic and 468′ paranoid) were selected to test the validity of emotion profiles gleaned from affective differential ratings, the affective differential methodology and the assumption that patients with different character structures have measurable differences in emotion profiles. Comparisons were made between the patient groups and between profiles gleaned from clinicians' ratings and the patients' self-reports. Emotion profile differences were demonstrated between paranoid and sociopathic patient groups. The clinicians' ratings tended to exaggerate the intensity of the emotions, making differences between profile types greater than those differences observed from patient self-reports. The results supported the hypothesis that persons with different character structures have different emotion profiles but not to the degree first reported by clinicians.
The Raven Progressive Matrices protocols of 88 narcotic addicts, divided into four MMPI profile pattern groups, were scored for avoidable errors. Ss having psychotic-like profiles (428′ and 987′) made significantly more avoidable reasoning errors than Ss with sociopathic patterns (42′ and 49′). These data were interpreted as evidence of the sensitivity of avoidable error measures to disturbances in consistency and accuracy of comparative and analogical reasoning performance. It was suggested that avoidable error indices might be used to (a) judge the effects of pathological ideation upon complex reasoning, (b) estimate potential level of intellectual functioning in clinical populations, and (c) serve as a criterion for treatment efficacies.
The Ravens Progressive Matrices (RPM), a test of intellectual ability, was administered to 396 male narcotic users. Norms are given, and concepts basic to the validity and reliability of the RPM tested. Significant shifts were found in item order in sets A, B, C, and D. Differences were not considered crucial for each set, which was progressively more difficult than the preceding set; thus the total structure of the test was supported by the sample. The discriminative power of most items ranged from good to excellent. In investigating properties of distractors, answer four was chosen significantly more often than other alternatives as the wrong answer in sets C, D and E identifying the possible operation of a positional distractor. Test-retest reliability, content and concurrent validity coefficients were of the order of .8. Correlation of formal education with RPM was of the order of .2. Previously available normative data on patient samples ae extended and use of the RPM as a measure of intellectual performance relatively free from language and cultural bias is supported.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
