Confirmatory factor analysis of the Kaufman Adolescent and Adult Intelligence Test with young adolescents

This study examined the factor structure of the Kaufman Adolescent and Adult Intelligence Test (KAIT) in 375 11- to 14-year-olds (normative sample) and 60 sixth- and eighth-graders (cross-validation sample). Previous exploratory and confirmatory factor analyses of the KAIT have included optional subtests, which are often not administered in practice, and have not tested oblique versus orthogonal two-factor models. In this study, three factor models were tested via confirmatory factor analysis for the six core subtests of the KAIT: a one-factor general intelligence (g) model, an orthogonal fluid intelligence (Gf)-crystallized intelligence (Gc) model, and an oblique Gf-Gc model. The orthogonal Gf-Gc model fit poorly in both samples. The g model fit only the cross-validation sample. The oblique Gf-Gc model fit both samples and fit significantly better than the g model in both samples. Additional tests of factor structure, path coefficients, and covariance between Gf and Gc indicated that the data from both samples fit even the most restrictive oblique Gf-Gc model tested. KAIT users can be confident that the Fluid and Crystallized IQs from the KAIT are adequate representations of a robust and interpretable factor structure when only the core subtests are administered to young adolescents.     

Using Score Equating and Measurement Invariance to Examine the Flynn Effect in the Wechsler Adult Intelligence Scale

The Flynn effect (FE; i.e., increase in mean IQ scores over time) is commonly viewed as reflecting population shifts in intelligence, despite the fact that most FE studies have not investigated the assumption of score comparability. Consequently, the extent to which these mean differences in IQ scores reflect population shifts in cognitive abilities versus changes in the instruments used to measure these abilities is unclear. In this study, we used modern psychometric tools to examine the FE. First, we equated raw scores for each common subtest to be on the same scale across instruments. This enabled the combination of scores from all three instruments into one of 13 age groups before converting raw scores into Z scores. Second, using age-based standardized scores for standardization samples, we examined measurement invariance across the second (revised), third, and fourth editions of the Wechsler Adult Intelligence Scale. Results indicate that while scores were equivalent across the third and fourth editions, they were not equivalent across the second and third editions. Results suggest that there is some evidence for an increase in intelligence, but also call into question many published FE findings as presuming the instruments' scores are invariant when this assumption is not warranted.

A revalidation of the Thurstone Test of Mental Alertness as a brief measure of intelligence through comparison with the Wechsler Adult Intelligence Scale-III

In earlier research, Rossini, Wygonik, Barrett, and Friedman (1994) demonstrated that the Thurstone Test of Mental Alertness (TMA) is a valid, brief measure of intelligence by comparing it to the Wechsler Scale of Adult Intelligence-Revised, which was at that time the "gold standard" of IQ assessment. Since that study, the WAIS has again been revised and reissued in a third edition, the WAIS-III. We assessed the relationship between scores on the Thurstone Test of Mental Alertness and this latest WAIS test to see if there is still a predictive relationship between the two tests. Correlations between the two tests and the accuracy of TMA point estimates of IQ indicate that the Thurstone Test of Mental Alertness remains a viable brief measure of adult intelligence.     

Genetic,Maternal, School,Intelligence, and Media Use Predictors of Adult Criminality: A Longitudinal Test of the Catalyst Model in Adolescence through Early Adulthood

The catalyst model suggests that adult criminality arises from the interaction of genetic and proximal social influences such as family influences, but that distal social influences such as media exposure have only negligible influence. This article uses data from a 13-year longitudinal study of adolescent health to examine the catalyst model. As expected by the catalyst model, adult criminality was best explained by a confluence of genetic and proximal social risk factors. The influence of media exposure on adult criminality was negligible. Implications of these findings for both theory and policy are discussed.     

Dyadic short forms of the Wechsler Adult Intelligence Scale-III

Various short forms of the Wechsler Adult Intelligence Scale (WAIS)/WAIS-R have been developed to obtain estimates of overall intellectual level, although little research of WAIS-III short forms has been published to date. Full Scale IQ (FSIQ) estimatesfromfour WAIS-III dyadic short forms were obtained by entering selected subtest scores from a mixed neurologic/ psychiatric sample (n = 196) into regression equations. Results were cross validated on a second sample (n = 57). Within both samples, WAIS-III FSIQ scores were highly correlated (r = .90-.92, p < .001) with estimated FSIQ scores. Estimated FSIQ fell within 5 points of actual FSIQ in 49% to 74% of cross-validation cases and within 10 points of actual FSIQ in 81% to 93% of the sample. Comparable to findings from previous short-form investigations, actual and estimated FSIQ classification levels agreed in 46% to 67% of cases in the cross-validation sample. These dyadic WAIS-III forms appear appropriate for obtaining gross estimates of FSIQ in similar populations, although caution is recommended in interpreting estimated IQ scores.     

The location of the Trait Emotional Intelligence in the Zuckerman's Personality Model space and the role of General Intelligence and social status

The aim of this study was to investigate the relationships between Emotional Intelligence (EI) measured by the Trait Emotional Intelligence Questionnaire (TEIQue) and personality measured by the Zuckerman‐Kuhlman‐Aluja Personality Questionnaire (ZKA‐PQ) with the purpose of analyzing similarities and differences of both psychological constructs. Additionally, we studied the relationship among EI, personality, General Intelligence (GI) and a social position index (SPI). Results showed that the ZKA‐PQ predicts the 66% (facets) and the 64% (factors) of the TEIQue. High scores in EI correlated negatively with Neuroticism (r: –0.66) and Aggressiveness (r: –0.27); and positively with Extraversion (r: 0.62). Oblique factorial analyses demonstrated that TEIQue scales were located basically in the Neuroticism and Extraversion factors. The SPI and GI no loaded in any factor. These findings showed that EI is a not a distinct construct of personality and it cannot be isolated in the ZKA‐PQ personality space. GI is related with the SPI (r: 0.26), and EI correlated with GI (r: 0.18) and SPI (r: 0.16). Nevertheless, we found differences between GI high groups and the TEIQue and ZKA‐PQ factors when controlling age and sex. These findings are discussed in the individual differences context.     

The Wechsler Adult Intelligence Scale (WAIS), but not the Defence Mechanism Test (DMTm), separates schizophrenics and normal controls in a factorial cluster analysis

Ten schizophrenic patients and ten healthy control subjects matched with respect to sex, age and education were tested by a psychological test battery including WAIS, WCST, FAS and a modified version of the tachistoscopic Defence Mechanism Test (DMTm). In a Q-factor analysis two factors were derived in the analysis of DMTm test scores. The distribution of cases among these factors was wholly at random. On the other hand, when analysing WAIS scores, five factors were derived and schizophrenic cases as well as control subjects were almost unequivocally clustered by different factors. It is argued that also if an unequivocal categorisation of cases had been achieved in the analysis of DMTm data, such a finding might well have been interpreted as an effect of anomalies in cerebral structures assumed to be of critical importance in the filtering of signals in the stream of visual perception. The existence of such anomalies in schizophrenics is now well established by neuroimaging as well as postmortem studies, and findings are also well in accordance with phenomenological and physiological data. The failure of DMTm to separate schizophrenic and control subjects does thus make the second and important step in a discussion on validity entirely superfluous, namely whether signs recorded really measure what they are assumed to measure, in this case defence mechanisms in a psychoanalytic sense.     

General intelligence,temperament, and the Matching Familiar Figures Test

To investigate the relationship between general intelligence g and temperament, highly intelligent 10-year-old children (N = 151) were compared with classmates of the same gender and socio-economic status but of average intelligence (N = 134). The two ability groups were administered the Matching Familiar Figures Test (MFFT) during home visits. The parents and teachers rated the temperament of the children. The results showed a consistent pattern: highly intelligent children are more task-oriented, e.g. less distractible and more controlled than their average counterparts. In the MFFT, gifted children not only gave a higher percentage of correct answers, but also showed longer (!) reaction times.     

The validity of the Comprehensive Test of Nonverbal Intelligence as a measure of fluid intelligence

The current investigation examined the validity of the Comprehensive Test of Nonverbal Intelligence (CTONI), an intelligence test that is purported to measure fluid intelligence. The CTONI was evaluated in comparison with the Kaufman Adolescent and Adult Intelligence Test (KAIT), an established measure of fluid and crystallized intelligence. Ninety-seven adults were administered these instruments in counterbalanced order. Results indicated that the sample's mean CTONI Nonverbal IQ (NIQ) deviated significantly from the mean KAIT Crystallized, Fluid, and Composite IQs. The CTONI mean NIQ underestimated KAIT Fluid and Composite IQs when individual participants were subdivided into existing KAIT ability categories and mean score comparisons were made. Results also indicated that the CTONI NIQ correlated strongly and positively with the KAIT Composite and Fluid IQs. Furthermore, the CTONI Geometric NIQ scale clearly demonstrated discriminant and convergent validity, whereas, the CTONI Pictorial NIQ (PNIQ) did not.     

Development and Validation of a Situational Judgment Test of Emotional Intelligence

The present study describes the development and validation of a situational judgment test (SJT) of emotional intelligence (EI). Initially, 80 situations and three response alternatives for each situation were created based on the available theoretical models. Principal component factor analysis with direct oblimin rotation of data (N = 213) yielded a three‐factor structure with 46 items. These factors were (1) utilizing own emotion, (2) sensing other's emotion, and (3) understanding emotional context. Additional studies showed that the measure had good internal consistency and test‐retest reliability. None of the three factors strongly correlated with the Big Five factors of personality (NEO Five‐Factor Inventory, thus establishing its identity as a construct distinct from personality. Findings of confirmatory factor analysis on secondary data reconfirm the three‐factor model for a 46‐item SJT of EI. The second study also found no correlation among these three factors, intelligence scores measured using Raven's Matrices, and trait EI score measured using the Trait Emotional Intelligence Questionnaire. The third study was conducted in order to determine the relationship of SJT of EI with academic achievement and life satisfaction. All three factors of SJT‐based EI measure were significantly associated with academic achievement and life satisfaction.     

Factor structure of the Wechsler Adult Intelligence Scale-III in schizophrenia

This report examines and compares the factor structure of the new edition of the Wechsler Adult Intelligence Scale (WAIS-III) in a sample of chronic schizophrenia and schizoaffective disorder outpatients (n = 120) and an age-matched sample of individuals drawn from the WAIS-III standardization sample (n = 200). Exploratory and confirmatory factor analyses similar to those reported by the developers of the scale suggested that a model of WAIS-III performance with correlated factors for verbal comprehension, perceptual organization, working memory, and processing speed fit the data from the schizophrenia sample as well as it fit the nonclinical comparison sample and fit the data from both samples better than alternative models.
