Mexican- and Anglo-American differences on the psychological screening inventory

This study investigated differences between Mexican- and Anglo-American college students on the Psychological Screening Inventory (PSI; Lanyon, 1970, 1973)-a brief personality instrument designed to detect persons who might benefit from more extensive evaluations in mental health settings. Further, this study controlled for the Mexican Americans' acculturation level, age, and socioeconomic status (SES), as these variables have routinely been shown to covary with other psychosocial variables. From data on 107 Mexican-American and 105 Anglo-American college students, we found that Mexican-American subjects had higher PSI scores on the Alienation and Defensiveness subscales and lower scores on the Social Nonconformity and Expression subscales than did Anglo-American subjects. With acculturation covaried, however, these differences were no longer statistically significant. With age and SES covaried, the two ethnic groups differed on Alienation, Expression, and Defensiveness, suggesting that Mexican Americans' performance on the PSI varies as a function of acculturation, age, and SES. Implications of these findings are discussed.     

Construct validity of the misrepresentation scales of the psychological screening inventory

This study provides construct validity evidence and reliabilities (consistency and stability) for 5 misrepresentation (response distortion) scales of the Psychological Screening Inventory (PSI; Lanyon, 1970, 1973, 1978) in assessing 3 constructs: exaggeration of psychopathology, exaggeration of personal virtue, and exaggeration of health problems. Using data from forensic cases, the existence and independence of these 3 constructs were confirmed in data from the MMPI-2 (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) and the Balanced Inventory of Desirable Responding (Paulhus, 1986, 1991). The PSI scales were then shown to load highly on these constructs. The PSI scales also showed the expected patterns when their mean scores were examined for 15 sets of responses from participant groups with varied motivations to misrepresent. We present receiver operating characteristic data to show the success of the scales in distinguishing between simulators and appropriate comparison groups. Using the same data, we also present classification accuracy in terms of positive predictive power and negative predictive power based on a sensitivity level of 90% and misrepresentation base rates of .20 and .10.     

A new counselling inventory

The construction of a counselling inventory for use by teachers and counsellors in identifying those pupils most in need of personal counselling is described The inventory consists of statements in six factorially distinct areas: (i) relationship with teachers, (ii) relationship with family, (iii) relation-ship with peers, (iv) social confidence, (v) irritability and (vi) health Evidence of reliability and validity is reported.     

Impacts of psychological science on national security agencies post-9/11

Psychologists have been an integral part of national security agencies since World War I, when psychological science helped in personnel selection. A robust infrastructure supporting wider applications of psychology to military and intelligence problems developed further during World War II and the years following, primarily in the areas of testing, human factors, perception, and the decision sciences. Although the nature of the attacks on 9/11 raised the level of perceived need for increased human-based intelligence, the impacts of psychologists on the policies and practices of national security agencies in the decade since have not increased significantly.     

Ryff's psychological well-being inventory: factorial structure and life history correlates among Japanese university students

The theoretical model of psychological well-being that encompasses six domains (self-acceptance, positive relations with others, autonomy, environmental mastery, purpose in life, and personal growth) was tested with a Japanese university student population (N = 574) using a Japanese translation of Ryff's 1989 Psychological Well-being Inventory. A factor structure similar to Ryff's original model emerged. Both depression and anxiety correlated only moderately with scores on some subscales of the inventory, suggesting the relative independence of these dimensions of psychological well-being and negative affectivity. With negative affectivity controlled, some early life experiences were significantly linked with psychological well-being: relationships with romantic partners were linked with greater autonomy and experiences which enhance self-esteem were liked with greater personal growth. Careful psychometric work on the Japanese version is required to use the scale; then a replication and extension of the present study would be feasible.     

A psychometric investigation of Eysenck's personality inventory

Eysenck's personality inventory (EPI) was administered to 653 females and 666 males. Item analyses were carried out for the subsamples and the combined sample. In addition hierarchical oblique factor analysis was applied to the data. The purpose of both item and factor analysis was to examine the psychometric properties of the EPI in regard to (a) the homogeneity of the scales, in terms both of internal and external item-scale relationships (b) the univocality of the scales assessed in factor analytic terms. It was found that the neuroticism scale was superior to the extraversion scale in both these respects.
