Processing of persuasive in-group messages

Two studies investigated the processes mediating the persuasive impact of messages representing in-group opinions. In the 1st study, subjects read either a strong or a weak message attributed to either an in-group member or to another group. Subjects were more persuaded by a strong message from the in-group than a weak one, suggesting content-focused processing of the in-group message. Subjects were equally unpersuaded by either a strong or a weak message from the other group, and showed little sign of message processing. In the 2nd study, Ss listened to in-group or other-group messages about issues that varied in their relevance to in-group membership. When the issue was relevant to the in-group, subjects were persuaded by a strong message from the in-group, unpersuaded by a weak message from the in-group, and equally unimpressed by strong and weak messages from the other group. When the issue was irrelevant to the in-group, subjects accepted the position advocated by the in-group regardless of message quality, and again ignored messages from the other group. These results suggest that increased message processing, and not merely the impact of source persuasion cues, can underlie in-group-mediated attitude change.     

Alexithymia among empirically derived subgroups of chronic back pain patients

A seeded cluster analysis procedure was applied to the Minnesota Multiphasic Personality Inventory (MMPI) profiles of 102 male and 63 female back-pain patients. For both men and women, the resulting subgroups were found to correspond closely to similar subgroups obtained in several previous investigations. New data on the psychometric properties of the MMPI Alexithymia scale (Kleiger & Kinsman, 1980) are presented. Significant differences in alexithymia among empirically derived MMPI subgroups were found in the male sample only.     

Contingent reinforcement effects on movement responses of prison inmates to the Holtzman Inkblot Technique

Prison inmates were administered the Holtzman Inkblot Technique (HIT) under conditions of either verbal or nonverbal reinforcement of movement responses. Overall, there were no differences among the verbal, nonverbal, and control groups. Inmates charged with violent crimes were found to give the fewest movement responses. With crime category controlled, more movement responses were given under nonverbal conditions. There were no sex differences for movement responses but testing time increased significantly when administered by the female examiner.     

A comparison of two multidimensional health locus of control instruments

This study examined the factor structure, internal consistency reliability, and construct validity of the multidimensional health locus of control (MHLC) instruments developed by K.A. Wallston, B.S. Wallston, and DeVellis (1978) and Lau (Lau, 1982; Lau & Ware, 1981). Both measures were administered to a sample of Veterans Administration (VA) medical outpatients (N = 181). Only minimal evidence of convergence was found between corresponding scales of the two MHLC instruments. Low convergent validity appears attributable to the poor internal consistency reliability of the Lau-Ware subscales. Moreover, results of factor analysis largely supported the a priori factor structure of the K.A. Wallston et al. (1978) MHLC instrument but failed to support the factor structure of the Lau-Ware instrument. Health locus of control (HLC) dimensions that emerged from simultaneous factor analysis of both instruments were most consistent with a three-dimensional typology (i.e., Personal Control, Professional Control, and Chance) rather than the four-dimensional typology proposed by Lau (Lau, 1982; Lau & Ware, 1981). Implications for HLC conceptualization and measurement are discussed.     

The susceptibility of the Rorschach to malingering: a critical review

Empirical studies of malingering on the Rorschach are reviewed. Results from these studies are to this point inconsistent and inconclusive. Although several indices are related to malingering in individual studies, no specific malingering pattern has been found that replicates across studies. A methodological problem specific to this literature is discussed and future research designs are recommended.     

Genetic and environmental variation on the California Psychological Inventory vector scales

Three recently introduced vector scales for the California Psychological Inventory (CPI) were scored for the National Merit Twin Sample and subjected to a heredity-environment analysis. Confidence intervals for genetic and environmental parameters were obtained by a bootstrap method. Two of the scales, Internality (Vector 1) and Self-Realization (Vector 3), showed the substantial heritability and near-zero family environment effects typically found for personality scales, whereas Norm-Favoring (Vector 2) showed an appreciable effect of family environment and a nonsignificant heritability.     

Four Systems Anxiety Questionnaire (FSAQ): a self-report measure of somatic, cognitive, behavioral, and feeling components

This article presents the development of a 60-item self-report known as the Four Systems Anxiety Questionnaire (FSAQ). The FSAQ assesses anxiety on four components: somatic, cognitive, behavioral, and feeling. The FSAQ was given to 218 first-year university students, 54 anxiety patients attending clinical psychology departments, and 14 agoraphobic patients pre- and postpsychological treatment. Results reveal satisfactory reliability and validity levels. In addition, we proved that the FSAQ is sensitive to change following psychological treatment.     

Psychological assessment of catatonic schizophrenia

Probably due to the rarity of the disorder and the general inability of catatonic patients to cooperate with standardized assessment, no data exist documenting the psychological features associated with catatonic schizophrenia that may appear on psychological tests. This study utilized standard assessment techniques to examine clinical hypotheses regarding the psychogenic correlates of catatonic conditions from the performance of one man on psychological tests. In accordance with previous theory, test findings indicated frequent constriction, rigidity, and negativism in conjunction with compulsive traits. Experiences of cognitive and self-fragmentation were juxtaposed with a formal, mechanistic body ego; disorganization and discontinuity were countered with attempts at self-cohesion. Depressed feelings and human interest were apparent, although interpersonal relatedness was frequently characterized by an avoidant, distancing style.
