Personality Correlates of Confidence in One's Decisions

ABSTRACT Taylor and Brown (1988) hypothesized that certain illusions, such as unrealistic optimism, are predictably associated with positive affect, social skills, and intellectual functioning. To test this hypothesis, we obtained data from 162 students who first filled out a questionnaire containing dispositional measures of affect, social skills, and approaches to problem solving; in a second session they completed three tasks requiring difficult decisions, reporting their confidence in each decision. Accuracy of judgments was found to vary considerably from task to task, but confidence ratings showed a consistent pattern of individual differences. This result lent support to Taylor and Brown's hypothesis, as did other features of the data, most notably several small but significant Pearson r s between confidence ratings and dispositional variables. Removing the effects of accuracy from these r s reduced their magnitude very little; it yielded partial r s interpretable as evidence that illusory confidence is associated with personality traits which, in this case, load saliently on factors labeled ( a ) affective, and ( b ) cognitive/social.     

Marginal and mindful: deviants in social interactions

Master status people's behavior, physical appearance, or life circumstance is statistically unusual and centrally defining (e.g., the physically attractive, the obese, the intellectually gifted, the facially scarred, the talented, the athletic, Blacks, gays, the wealthy, rape and incest victims). These individuals were paired with people without such conditions. Each pair was left alone on a pretext and covertly videotaped. Pairs were then separated; each member spontaneously recalled information about her partner and the experimental room and provided a record of her thoughts and feelings during the interaction. As hypothesized, all master status Ss were particularly likely to be mindful in social interactions; they recalled detailed information about the situation and often took their partner's perspective during the interaction. The positive or negative connotations of the master status conditions were irrelevant in predicting Ss cognitions (mindfulness) but were critical in determining Ss behaviors (interaction strategies).     

Social support and immune function among spouses of cancer patients

This study investigated whether social support was related to immune function among spouses of cancer patients. Effects of depression and negative life events were examined as potential mediators. Results showed evidence of greater immunocompetence on 2 of 3 dynamic measures: natural killer cytotoxicity and proliferation response to phytohemagglutinin among spouses who reported high levels of social support. All six components of social support assessed by the Social Provisions Scale (Cutrona & Russell, 1987) were strongly related to these indices of immune function. No evidence was found for mediation by either life events or depression.     

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.     

Racial bias and the MCMI

We studied the scores obtained on the Millon Clinical Multiaxial Inventory (MCMI) by Black and White male psychiatric inpatients to determine the presence or absence of racial bias. In predicting psychopathology for the two races, comparisons of MCMI performance indicated significant differences for all diagnoses except the personality disorders. The subjects were then matched into two groups of 209 patients each, according to DSM-III psychiatric diagnoses. The data were analyzed at the item, scale, and structural levels. At the item level, application of the Mantel-Haenszel Procedure revealed that 45 of the 175 items of the inventory were answered significantly different by the two racial groups. Because this number was higher than what could be expected by chance, the finding suggested possible deficiencies in terms of the culture-fairness of the items used in the test. At the scale level, an analysis of variance (ANOVA) demonstrated that the scores obtained by the Black and White groups were significantly different in 9 of the 20 scales (Histrionic, Narcissistic, Antisocial, Paraphrenia, Hypomania, Dysthymia, Alcohol Abuse, Drug Abuse, and Psychotic Delusion). With the exception of the Dysthymic scale, all of the differences were in the direction of the Blacks obtaining a higher score than the Whites. At the structural level, however, a principal components factor analysis performed on each group resulted in factor structures that looked identical.     

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.     

Assessing object representations as a continuous variable: a modification of the concept of the object on the Rorschach scale

Current methods for assessing the quality of internalized object representations have not provided a continuous variable that simultaneously includes both an accuracy and a maturity component. A modification of Blatt, Brooks, Brenneis, and Schimek's (1976) Concept of the Object on the Rorschach scale that would combine the two components by weighting the quality of each response according to its form level was proposed. Initial discriminant and convergent validity of this modification was checked through correlations and multiple regression analyses using behavioral, diagnostic, and demographic data from 84 adolescent inpatients as dependent variables. Results indicate the modified score was directly related to measures of peer relatedness, intelligence, psychological health, and reality testing, and indirectly related to measures of psychosis and hostile, unmanageable behavior. The results support the utility of the modification for providing a continuous score that assesses both developmental maturity and accuracy, the two dimensions on which the concept of object representation is based.     

Assessment: what role the assessor?

The advent of automated assessment contains the seeds of both threat and promise for professional assessors. Placing the problem in the historical and sociological contexts, this article examines computer-based test interpretation (CBTI) and the frequently misunderstood role of actuarial data in relation to it. I argue that sound clinicianship is central not only to the development of adequate CBTI systems, but also to the systems' appropriate and skillful use in practice. When properly utilized by otherwise well-qualified clinicians, CBTI can substantially enhance practice.     

Learned resourcefulness, drinking, and smoking in young adults

The purpose of this study was to examine the relationship between learned resourcefulness and two common addictive behaviors, namely, drinking and smoking. Male and female college students (N = 175) completed the Self-Control Schedule (SCS), the Quantity-Frequency-Variability questionnaire, and a smoking history form. Learned resourcefulness was related to self-reported patterns of alcohol consumption; specifically, heavy drinking subjects were lower in learned resourcefulness than were light and moderate drinkers who, in turn, were lower in learned resourcefulness than were infrequent drinkers and abstainers. Learned resourcefulness was only modestly related to smoking, with students who had never smoked evidencing somewhat higher learned resourcefulness than ex-smokers and current smokers. Overall, these data provide correlational support for the notion that learned resourcefulness may protect young adults against substance abuse.     

A Rorschach investigation of narcissism and hysteria in antisocial personality

We investigated Rorschach responses associated with narcissism and hysteria in a group of antisocial personality disordered offenders. The Rorschach protocols of 42 subjects who met the criteria from the Diagnostic and Statistical Manual of Mental Disorders (3rd ed., rev. [DSM-III-R]; American Psychiatric Association, 1987) for antisocial personality disorder were analyzed using Exner's (1986) criteria for pairs, reflections, and personal responses, and Gacono's (1988) criteria for the impressionistic response. Severe, or primary psychopaths (n = 21), scoring greater than or equal to 30 on the Hare (1980) Psychopathy Checklist (PCL), were compared to moderate, or secondary pscyhopaths (n = 21), scoring less than 30 on the PCL. The mean number of pair and impressionistic responses did not significantly differ for the two antisocial groups. The highly psychopathic group, however, did exhibit a significantly greater mean number of reflection and personal responses. We discuss pair and reflection responses and their relationship to narcissism in psychopathic disturbance. We recommend interpreting the personal response within the context of the psychopathic character and view personal responses as expressions of narcissism and omnipotence in highly psychopathic subjects. We also hypothesize that the impressionistic responses are indicative of primitive dissociative processes and hysteria in psychopathic subjects, and that their presence provides construct validity for the work of Guze (1976) and others who suggested an underlying histrionic dimension to psychopathy.
