On the Construct Validity of Integrity Tests: Individual and Situational Factors as Predictors of Test Performance

Although integrity tests are widely applied in screening job applicants, there is a need for research for examining the construct validity of these tests. In the present study, a theoretical model examining the causes of destructive behavior in organizational settings was used to develop background data measures of individual and situational variables that might be related to integrity test scores. Subsequently, 692 undergraduates were asked to complete these background data scales along with (a) two overt integrity tests – the Reid Report and the Personnel Selection Inventory, and (b) two personality‐based measures – the delinquency and socialization scales of the California Psychological Inventory. When scores of these measures were correlated with and regressed on the background data scales, it was found that relevant individual variables, such as narcissism and power motives, and relevant situational variables, such as alienation and exposure to negative peer groups, were related to scores on both types of integrity tests. However, a stronger pattern of validity evidence was obtained for the personality‐based measures and, in all cases, situational variables were found to be better predictors than individual variables. The implications of these findings for the validity of inferences drawn from overt and personality‐based integrity tests are discussed.     

Behavioral assessment of pain detection and tolerance in monkeys

Cebus albifrons monkeys received electrical stimulation of the hindlimbs over a wide range of intensities. On trials signalled by a blue light, the animals were permitted to escape shock by pressing a disc, or shock was terminated after 8 sec (free escape). Escape force (disc pressure) was found to increase as stimulation intensity increased well beyond escape threshold, while shock duration curves reached plateau at the mid-range of intensities. The shock duration curves generated by free escape responses should be comparable to pain detection functions obtained by similar operations in humans, and the curves were stable over months of testing, as is generally found in pain-detection studies. On trials signalled by a red light, the animals received intense tail shock immediately after escape responses (punished escape), or, if they endured leg shock for 8 sec without escaping, then they could avoid tail shock with a panel press. The shock duration curves generated by punished escape responses should be comparable to pain tolerance functions as defined for human subjects, and the escape thresholds were considerably higher on red-light trials. As in human studies, the tolerance curves were not stable over repeated testing sessions, and some feature of the paradigm forced a progression toward extremely high levels of tolerance.     

The effects of Δ9 THC on cutaneous sensitivity and its relation to personality

Pain threshold/tolerance and vibration perception were studied in a sample of female frequent and infrequent cannabis users. Interactions with personality characteristics were examined using the EPI. Performance on all measures was investigated after oral administration of either 10mgΔ⁹ THC or 20 mg Δ⁹ THC. Results indicated that while the 10mg dosage produced no consistent changes in cutaneous sensory response, the 20 mg dosage was followed by lowering of the vibration threshold. Frequent and infrequent cannabis users differed in their response to the pain stimulus (pain tolerance scores were higher among infrequent users). They also differed with respect to the personality measure (frequent users had lower E, N and L scores). The findings provide experimental support for cannabis users' reports of enhanced sensory awareness consequent to drug intake. The results also show that frequent and infrequent cannabis users differ in pain response and personality characteristics.     

Ego development in adult women

Ego development in adult women was studied using Loevinger's Sentence Completion Test of Ego Development (SCT). The subjects were 163 women in a university nurse practitioner training program. Ego development scores were correlated with scores from personality tests and with interview data. Higher ego levels were related to personal adjustment, nurturance, responsibility, tolerance, enjoyment of children, inner control, capacity for status, and age. Improvement in ego level scores was found only for those at, or below, the self-aware level. The SCT, as scored for women, seems to be particularly sensitive to differences in responsible caring in relationships, an aspect of personality development often neglected by other tests.     

Emotion control and analgesia in labour

The role of personality in analgesic use during labour was investigated. When age, duration of labour and number of previous labours were controlled, significant relationships were uncovered between analgesic use and two personality variables: Hypochondriasis and Rehearsal. The results are discussed in relation to stimulus intensity control and emotion control models of pain tolerance.     

Personality disorders and response to outpatient treatment of chronic pain

As part of a comprehensive interdisciplinary evaluation conducted prior to participation in an outpatient chronic pain treatment program, the psychological status of 101 persons was assessed. The majority of participants was found to have a form of personality disorder, determined by conservative cutoff scores applied to their Millon Clinical Multiaxial Inventory (MCMI) profiles. DSM-III-R Cluster C disorders (i.e., Avoidant, Dependent, Obsessive-Compulsive, and Passive-Aggressive) were overrepresented in this sample. Subsequent analyses revealed that personality disorders were related to higher levels of self-reported distress and pain at both the beginning and the end of outpatient treatment. Differential responses to treatment were observed on self-report measures; however, few relations were found between personality disorder and physical therapist ratings of impairment and improvement. Implications for the assessment of personality disorders in outpatient pain treatment programs are discussed and appropriate intervention strategies are considered.     

A cross-cultural test of the personality integration hypothesis1

This study attempted to validate the psychological integration hypothesis by comparing the levels of psychological functioning of individuals from four cultural groups on three dimensions of personality. The personality attributes investigated were field-dependence/independence cognitive style, tolerance of ambiguity (an affective style variable) and machiavellianism (an index of stylistic orientation in interpersonal relationships). Subjects were 218 first-level supervisors from five industrial plants in Auckland, New Zealand. Comparisons of mean group scores on each personality variable showed that a similar rank order among the groups held for each personality variable. It was also found that, for the sample as a whole, there were positive intercorrelations between the personality variables. The symmetrical rank ordering of the groups on the personality variables was considered to indicate that members of each group had attained relatively similar levels of psychological development on each personality attribute. The relatively low levels of intercorrelations between the personality variables were held to indicate that they were measuring separate areas of psychological functioning.     

Sex differences and personality factors in responsivity to pain

This study investigated the relationship between measured levels of masculinity-femininity, social desirability, and responsivity to pain in men and women. The literature suggests that the two personality variables might provide an explanation for the common findings of higher pain thresholds and tolerances in men than in women. A significant interaction was found between masculinity-femininity and sex for pain thresholds. Analysis of this interaction indicated that for men, but not women, there was a significant correlation between masculinity-femininity and pain, where higher masculinity was associated with higher pain thresholds. However, this finding did not account for the sex difference in pain threshold. The sex of the subject remained a significant predictor of both pain thresholds and tolerances after allowing for the influence of masculinity-femininity, social desirability, and their associated interactions.     

Cognitive processes and computerized personality assessment

Several implications of the cognitive viewpoint on personality are tested and the predictive validity of cognitive processing variables is assessed with judgements of parents and friends as a criterion measure. Free recall of items was related to cognitive schemas but reaction time during score recall was not. Ease of faking as well as response latency during faking were not related to cognitive schemas. Intra-individual analysis revealed a consistent non-linear relationship between response latency and item score in all conditions of the experiment. Although some cognitive process variables were correlated with the criterion measures, adding these variables to item scores did not always increase the predictive validity.     

Drug tolerance and personality: Some implications for Eysenck's theory

Two previous studies, one of nitrous oxide and the other of amylobarbitone sodium, had shown that tolerance of these drugs, assessed by the ‘sedation threshold’ procedure, was influenced by an interaction between introversion-extraversion and neuroticism: tolerance was negatively correlated with E in High N subjects and positively with E in low N subjects. In a study described in the first part of this paper the same result was found for thiopentone among a group of 50 surgical patients, tested as part of their routine pre-operative procedure. The remainder of the paper is devoted to a more detailed analysis of this interactive effect, undertaken by combining the personality and sedation threshold scores from three studies. In this larger sample the previously observed results were broadly maintained, in that neurotic extraverts and normal introverts proved to have very low drug tolerance; the highest tolerance was found, however, in introverts with moderate, rather than very high, neuroticism. Comparison with similar data for a large group of neurotic patients revealed a somewhat different picture: the sedation thresholds of patients were sometimes predictable from their personality scores and sometimes from their diagnoses, the two not always coinciding. The results as a whole are discussed with reference to the possible neurophysiological mechanisms mediating depressant drug action and personality differences. Specifically it is suggested that some parts of the observed variation in drug tolerance might be explained by combining certain features of the modifications to Eysenck's theory of extraversion and neuroticism proposed, respectively, by Gray and by Claridge. However, it is considered that not all of the variation can be explained in this way and that other personality characteristics, probably those associated with ‘psychoticism’, are likely to prove important determinants of drug tolerance differences.     

The Effect of Anxiety on the Cognitive Functioning in Non-clinical Schizotypal Individuals

Schizotypal personality disorder (SPD) is characterized by eccentric behavior and perceptual distortions that closely resemble the patterns observed in those with schizophrenia. Schizophrenia and related personality disorders (i.e., SPD) are associated with deficits in sustained attention, slower than normal reaction times, and manifestations of working memory deficits and erratic cognitive tasks. The present study used the schizotypal personality scale (STA) to compare cognitive abilities of self-reported low schizotypic tendency subjects with high schizotypic tendency subjects. The group scores on the STA differed significantly. Those with high STA scores also tended to have higher state and trait anxiety scores based on the State-Trait Anxiety Inventory (STAI). The groups did not significantly differ on any of the demographic variables tested, including age, education, self-rated health status, and medication. Along with an executive function test, two computerized tasks tested subjects on reaction time and memory. Even when covariates (i.e., state, trait anxiety scores) were analyzed, there were no significant differences between the groups and tasks, although the gathered data showed trends in the expected direction.

Perceptual deprivation,extraversion—introversion and the autokinetic phenomenon

The present study examines the relationships between perceptual-deprivation tolerance and three variables: extraversion, the autokinetic (AK) phenomenon and field-dependence. In addition, the relationship between extraversion and autokinesis (AK) was investigated. Thirty-three male subjects were subjected to 3 hr of perceptual deprivation and, in addition, their scores on each of the three independent variables were obtained. It was found, as hypothesized, that perceptual-deprivation tolerance was negatively related to extraversion and positively related to the intensity of the AK effect. Field-dependence was not related to perceptual-deprivation tolerance. The correlation between extraversion and the autokinetic effect was significant but moderate. The nature of the relationship between these two variables is discussed.     

RATINGS OF ANXIETY-PRONENESS AND RESPONSES TO ELECTRICAL PAIN STIMULATION: Preliminary experiments in a group of young delinquents

A group of young delinquents clinically rated as manifesting a tendency to react with anxiety and tension was compared with a group from the same prison with predominantly 'psychopathic' traits according to clinical ratings. The delinquents were subjected to electrical pain stimulation and tested with a battery of tests and personality inventories. In line with the hypotheses, the more anxiety-prone delinquents showed greater sensitivity to pain, had lower scores in the Leg Persistence Test, shorter reaction times and more errors in an auditive choice reaction test. There were no significant differences with regard to the inventory variables.     

Personality correlates of heroic rescue during the holocaust

This study investigated the extent to which personality variables can be used to discriminate non-Jewish heroes of the Holocaust from bystanders and from a comparison group of prewar European immigrants who left their countries of origin prior to World War II. Eighty verified rescuers, 73 bystanders, and 43 immigrants were administered measures of locus of control, autonomy, risk taking, social responsibility, tolerance/authoritarianism, empathy, and altruistic moral reasoning. A three-group discriminant function analysis was able to correctly classify 80.2% of the sample by a combination of personality and demographic variables. When the bystanders and immigrants, who differed very little from each other, were grouped together and compared to the rescuers, the personality variables alone correctly classified 93.1% of the sample. Implications regarding the relationship between personality and altruistic behavior, as well as suggestions for future research are discussed.     

A cognitive neuropsychological and psychophysiological investigation of a patient who exhibited an acute exacerbated behavioural response during innocuous somatosensory stimulation and movement

We report findings from a cognitive neuropsychological and psychophysiological investigation of a patient who displayed an exacerbated acute emotional expression during movement, innocuous, and aversive somatosensory stimulation. The condition developed in the context of non-specific white matter ischaemia along with abnormalities in the cortical white matter of the left anterior parietal lobe, and subcortical white matter of the left Sylvian cortex. Cognitive neuropsychological assessment revealed a pronounced deficiency in executive function, relative to IQ, memory, attention, language and visual processing. Compared to a normal control group, the patient [EQ] displayed a significantly elevated skin conductance level during both innocuous and aversive somatosensory stimulation. His pain tolerance was also significantly reduced. Despite this, EQ remained able to accurately describe the form of stimulation taking place, and to rate the levels of pain intensity and pain affect. These results suggest that EQ's exaggerated behavioural response and reduced pain tolerance to somatosensory stimulation may be linked to cognitive changes, possibly related to increased apprehension and fear, rather than altered pain intensity or pain affect per se.     

Motives, values and moral judgments

This study examined McClelland's (1981) hypothesis that operant and respondent measures of personality are orthogonal and assess different dimensions of personality structure. An operant measure of motives, a sentence completion test, and two respondent measures of cognitive schema variables, the Rokeach Value Survey and the Defining issues Test, were administered to 311 subjects. As predicted and in support of McClelland's hypothesis, 69% of the correlations between the respondent measures were significant at the alpha .05 level of probability versus 14% of the correlations between the operant and respondent measures. Further, within the domain of cognitive schema variables, it was theoretically possible to predict which values would correlate with different levels of moral judgment. The findings were discussed in terms. of their implications for person x situation models of social interaction and the prediction of criterion variables from typologies of personality.     

Differences in High and Low Anxiety Sensitive Women's Responses to a Laboratory‐Based Cold Pressor Task

Anxiety sensitivity (AS) has been linked to a variety of disabling chronic health conditions, including pain‐related conditions. A recent study has found that healthy women with high AS reported significantly higher levels of sensory and affective pain on an experimental cold pressor task compared to women with low AS. However, this study found no differences between AS groups for pain tolerance or pain threshold. In the present study, which was designed to replicate and extend these findings, 90 undergraduate university women were selected for inclusion in 1 of 2 AS groups (high or low) based on their screening scores on a 16‐item measure of AS. Participants were tested individually on a lab‐based cold pressor task using a variety of self‐report and observer‐measured variables. Data analyses revealed that, as expected, the high AS participants reported significantly more fear in response to the cold pressor on a relevant item of the McGill Pain Questionnaire – Short Form (SF‐MPQ) than did the low AS participants. Also as expected, the high AS participants reported more pain in response to the cold pressor on the Present Pain Index (PPI) of the SF‐MPQ than did the low AS participants. High AS participants did not differ from low AS participants on other aspects of the cold pressor response (e.g. pain threshold, pain tolerance, pain recovery). These results support the role of pain‐related fear as a mediating variable between AS and increased perceived pain intensity.     

Psychosocial maturity and interpersonal attraction

Psychosocial maturity (PSM), assessed by scores on the Inventory of Psychosocial Development, was related to interpersonal behavior. In Experiment I PSM and proportion of attitude similarity was varied using Byrne's attraction paradigm in a between-subjects design. The personality variable failed to affect attraction. In Experiment II PSM and proportion of attitude similarity were manipulated in a within-subjects design. High PSM subjects rated the stranger significantly higher in attraction at high levels of similarity and significantly lower in attraction at low levels of similarity when compared to Low PSM individuals. The results were discussed in terms of design differences in personality research and potential mechanisms by which PSM affects attraction (self-esteem and/or competence).
