Narcissism and empathy: validity evidence for the Narcissistic Personality Inventory

Three empathy questionnaires were correlated with scores on the Narcissistic Personality Inventory (NPI), and the predicted negative relationship was observed in two of the three cases. In addition, the Exploitiveness/Entitlement (E/E) subscale of the NPI was inversely related to all three empathy scales and directly related to another hypothesized measure of narcissism. Unexpected negative correlations between the E/E subscale and social desirability scales were interpreted as evidence of E/E subscale sensitivity to the manipulative dimension of narcissistic relationship styles. These data further support the construct validity of the NPI in general and of the Exploitiveness/Entitlement subscale in particular.     

Further evidence for the validity of the Need Inventory of Sensation Seeking

The Need Inventory of Sensation Seeking (NISS) by Roth and Hammelstein (2012) conceptualizes sensation seeking as a motivational trait, a need for stimulation that can provoke different behaviors. Extending the area of application to the field of sexuality, the results of an online survey with a convenience sample (N = 368) provided evidence that the NISS outperforms traditional measures of sensation seeking. In a series of hierarchical regression analyses, the NISS added incremental variance in predicting the number of sexual partners and the frequency of extreme sexual behaviors and fantasies. No relationship between the NISS and pornography use was found. Moreover, the NISS subscale Need for Stimulation performed better than the subscale Avoidance of Rest. Overall, the study supported the assumption that the NISS is a valid and reliable instrument in the area of sexuality.     

Further evidence for construct validity of the Interpersonal Relationship Inventory: Japanese version

The Japanese versions of the Interpersonal Relationship Inventory, the Satisfaction with Life Scale, and the Self-esteem Scale were administered to 153 Japanese college students. Weak to modest significant correlations between scores on the inventory and measure of life satisfaction and self-esteem provided further incremental support for construct validity of the inventory.     

Evidence for the criterion validity and clinical utility of the Pathological Narcissism Inventory

In this study, the authors evaluated aspects of criterion validity and clinical utility of the grandiosity and vulnerability components of the Pathological Narcissism Inventory (PNI) using two undergraduate samples (N = 299 and 500). Criterion validity was assessed by evaluating the correlations of narcissistic grandiosity and narcissistic vulnerability with established indices of normal personality traits, psychopathology and clinical concerns, and pathological personality traits. Overall, the pattern of correlations supported the convergent and discriminant validity of grandiose and vulnerable conceptualizations of pathological narcissism as measured by the PNI. Clinical utility was assessed by evaluating the extent to which clinicians without specific training in pathological narcissism as well as clinicians with expertise in pathological narcissism could accurately predict the correlates of PNI grandiosity and vulnerability with normal and pathological personality traits and psychopathology. The r(contrast-cv) coefficient provided a global index of accuracy in clinicians' predictions that was more fully elaborated by examining systematic discrepancies across groups. Overall, novice and expert clinicians were generally able to predict criterion correlations, with some exceptions (e.g., counter to predictions, pathological narcissism was negatively associated with treatment resistance). These results provide further evidence regarding the validity and utility of the narcissistic grandiosity and narcissistic vulnerability constructs as measured by the PNI.     

Further evidence for the validity of the Taylor Aggression Paradigm

The purpose of this study was to evaluate the validity of a modified version of the Taylor Aggression Paradigm (TAP) as a measure of direct physical aggression. Hypotheses were generated from recent theory pertinent to the categorization and measurement of aggressive behavior as well as widely supported effects of alcohol intoxication and gender on aggression. Participants were 328 (163 men and 165 women) healthy social drinkers between 21 and 35 years of age who completed self-report personality inventories designed to assess one's propensity toward direct physical aggression, verbal aggression, trait anger, and hostility. Following the consumption of either an alcohol or a placebo beverage, participants were tested on the TAP, in which mild electric shocks were received from, and administered to, a fictitious opponent during a competitive task. Direct physical aggression was operationalized as the shock intensities (i.e., first trial shock intensity, mean shock intensity, proportion of highest shock) administered to the fictitious opponent. Although all self-report measures were significantly associated with the three TAP indices, the associations involving physical aggression were strongest. In addition, self-report measures of physical aggression consistently predicted higher levels of aggression on the TAP indices in men, compared with women, and in intoxicated, relative to sober, participants. Taken as a whole, this pattern of findings provides further evidence for the validity of the TAP as a measure of direct physical aggression for men and women.     

The development of the Minnesota Multiphasic Personality Inventory

The Minnesota Multiphasic Personality Inventory (MMPI) was constructed at the University of Minnesota before and during World War II. In its developmental phase, the MMPI was conceputalized as an efficient way of detecting psychiatric disturbance. The test's construction was made possible by atypical cooperation between psychologists and psychiatrists, within the context of a crisis in the U.S. public mental health care system. The MMPI was designed to meet the diagnostic needs of psychiatrists. As such, it represented the operationalization of medical hegemony. However, the interpretation of the MMPI shifted significantly after the war, reflecting organizational reform in clinical psychology and changing professional relationships between psychologists and psychiatrists.     

Further exploration of the Vedic Personality Inventory: validity, reliability and generalizability

The purpose of this study was to explore the validity, reliability, and generalizability of the Vedic Personality Inventory which consists of constructs derived from the Vedic literature of India. There were 57 participants (20 men, 37 women). The mean age was 44.3 yr. (SD= 15.1). The sample was predominantly older, well-educated women who volunteered to participate as respondees to invitations to participate posted in supermarkets, churches, colleges, and on the internet. Analysis yielded statistically significant correlations for scores on the Vedic Personality Inventory and on the Daily Spiritual Experiences Scale and the Brief Symptom Inventory, each of which measures domains of interest addressed by the first inventory.     

Further evidence of reliability and validity for the driving anger expression inventory

This study provided evidence of reliability and validity for the four scales of the Driving Anger Expression Inventory. Alpha reliabilities for scales ranged from .84 to .89. Measures of aggressive anger expression while driving (Verbal Aggressive Expression, Personal Physical Aggressive Expression, and Use of the Vehicle to Express Anger scales) correlated positively with each other and negatively with the Adaptive/Constructive Expression scale. Scores on the three aggressive forms of anger expression correlated positively with trait anger and measures of driving-related anger, aggression, and risky behavior, whereas scores on the Adaptive/Constructive Expression scale correlated negatively with these variables. Reports of aggressive and risky behavior correlated most strongly with the Use of the Vehicle to Express Anger scale. Forms of anger expression were minimally or uncorrelated with rated trait anxiety and reports of moving violations, close calls, and accidents. Findings replicated earlier findings and provided further evidence for the reliability and validity of the Driving Anger Expression Inventory.     

Convergent validity of the Chinese Personality Assessment Inventory and the Minnesota Multiphasic Personality Inventory-2: preliminary findings with a normative sample

We examined the convergent validity of the Chinese Personality Assessment Inventory (CPAI; Cheung, Leung, et al., 1996), an indigenously constructed measure, by comparing its patterns of correlations with the MMPI-2 (Butcher et al., 2001). A valid sample of 147 Chinese students took both the CPAI and the MMPI-2. Results provide preliminary support for the convergence between most of the CPAI clinical scales and the relevant MMPI-2 scales. The CPAI personality scales further illustrated the patterns of personality features associated with the MMPI-2 scales in a Chinese cultural context. We discuss discrepancies in the correspondence between a number of CPAI and MMPI-2 clinical scales.     

Further evidence for the validity of assessment center dimensions: a meta-analysis of the incremental criterion-related validity of dimension ratings

This study investigates the incremental variance in job performance explained by assessment center (AC) dimensions over and above personality and cognitive ability. The authors extend previous research by using meta-analysis to examine the relationships between AC dimensions, personality, cognitive ability, and job performance. The results indicate that the 7 summary AC dimensions postulated by W. Arthur, Jr., E. A. Day, T. L. McNelly, & P. S. Edens (2003) are distinguishable from popular individual difference constructs and explain a sizeable proportion of variance in job performance beyond cognitive ability and personality.

Factor comparison of two Minnesota Multiphasic Personality Inventory short forms

A sample of 315 valid Minnesota Multiphasic Personality Inventory (MMPI) protocols were selected from inpatient files and scored for both the MMPI-168 and Faschingbauer Abbreviated MMPI short forms. Each short form was then factor-analyzed by a principal axis strategy with varimax rotation. The six factors extracted from each short form were then compared as to their similarity by use of the s index. This procedure showed five of the six factors in each short form as having a significant relationship of the pattern of salient variables they had in common with the complimentary factors of the other form. These data suggest that both short forms, though based on different construction methodologies, share the same underlying personality attributes. Future research is suggested to replicate these results and extend them to the full MMPI.
