International comparison of group differences in general mental ability for immigrants versus non‐immigrants

Globalization has led to increased migration and labor mobility over the past several decades and immigrants generally seek jobs in their new countries. Tests of general mental ability (GMA) are common in personnel selection systems throughout the world. Unfortunately, GMA test scores often display differences between majority groups and ethnic subgroups that may represent a barrier to employment for immigrants. The purpose of this study was to examine differences in GMA based on immigrant status in 29 countries (or jurisdictions of countries) throughout the world using an existing database that employs high‐quality measurement and sampling methodologies with large sample sizes. The primary findings were that across countries, non‐immigrants (n = 139,464) scored approximately half of a standard deviation (d = .53) higher than first‐generation immigrants (n = 22,162) but only one‐tenth of a standard deviation (d = .12) higher than second‐generation immigrants (n = 6,428). Considerable variability in effect sizes was found across countries as Nordic European and Germanic European countries evidenced the highest non‐immigrant/first‐generation immigrant mean differences and Anglo countries the smallest. Countries with the lowest income inequality tended to evidence the highest differences in GMA between non‐immigrants and first‐generation immigrants. Implications for GMA testing as a potential barrier to immigrant employment success and the field's current understanding of group differences in GMA test scores will be discussed.     

Body Boundary and Psychological Control in an Arthritic Population

This study investigated the relationship of body boundary and psychological control in a sample of 115 arthritic and connective tissue disorder patients. Barrier and penetration scores in the Rorschach were compared with ratings of outer and inner control. A positive significant relationship was found between barrier and outer control and a negative significant relationship was found between penetration and inner control. It is indicated that in this population a combination of high barrier and low penetration is associated with good psychological control while a combination of low barrier and high penetration is associated with poor psychological control. A combination of high barrier and high penetration is associated with poor inner control and a combination of low barrier and low penetration is associated with poor outer control.     

Increasing the reliability of Wechsler Intelligence Scale for Children--Third Edition difference scores with reliable component analysis

Wechsler Intelligence Scale for Children--Third Edition index score differences are generally interpreted cautiously, if at all, primarily because of their poor reliability. On the basis of prior analyses with the Wechsler Adult Intelligence Scale--Third Edition (J. C. Caruso & N. Cliff, 1999), it was hypothesized that differences between scores defined by reliable component analysis would have higher reliability than those defined by traditional equal weighting. Differences between the reliable component scores showed substantially higher reliability than equally weighted score differences. The differences between reliable component scores were also substantially more reliable than those derived from the weighted scores suggested by K. C. H. Parker and L. Atkinson (1994). Using the weights provided in this article will allow researchers and practitioners to compute the RCA scores and have the assurance of high reliability with its attractive consequences.     

Changing people’s attitudes and beliefs toward driving through floodwaters: Evaluation of a video infographic

Despite awareness of campaigns such as ‘Turn Around, Don’t Drown’ and the Australian state of Queensland’s ‘If It’s Flooded, Forget It’, people continue to drive through floodwaters, causing loss of life, risk to rescuers, and damage to vehicles. The aim of this study was to develop a video infographic that highlights the dangers of driving through floodwaters and provide safety tips to reduce the risk, and to evaluate its effectiveness in changing the beliefs and intentions of Australian adults toward this risky driving behaviour. This study adopted an online three-wave non-controlled pretest–posttest design. Australian licensed drivers (N = 201, male = 41, female = 160; M_age = 34.10) self-reported their demographic and psychological variables (intention, attitude, subjective norm, barrier self-efficacy, risk perception, anticipated regret, perceived susceptibility, and perceived severity) at baseline (T1), immediately post-intervention (T2), and at a one-month follow-up (T3). Messages in the video infographic were developed based on psychological theory and empirical evidence, using data on causal factors derived from coronial records and the findings of behavioural research. Results indicated that men had significantly higher intentions and attitudes and significantly lower barrier self-efficacy, risk perception, anticipated regret, perceived susceptibility, and perceived severity with respect to driving through floodwater than women. Statistically significant time x gender interaction effects were also found; attitude and subjective norm were significantly lower between T1 and T2 for both men and women but scores between T2 and T3 remained significantly lower for women only. In addition, perceived susceptibility and perceived severity scores were significantly higher in women across T1 and T2, with the difference maintained at T3. In contrast, there were no differences in scores across the three-time points for men. The implications of these findings for road safety and drowning prevention messages targeting drivers during floods are discussed.     

The Timing of Counselor Contact in the Use of a Computer Information Delivery System With Adult Career Counseling Clients

Treatment outcome differences based on the timing of counselor contact in the use of a computer information delivery system were investigated. The results indicate significant differences between scores for the postintervention counseling and control groups on the Career Decision Scale. Results also indicate significant differences between the postintervention and en-route counseling groups for scores on the Computer Liking subscale of the Computer Attitude Scale. Implications are discussed.     

The relationship between parental divorce and the child's body boundary definiteness

The relationship between parental divorce and body boundary definiteness was studied in a group of Swedish children. Rorschach tests were administered to a nonclinical sample of 90 school children between the ages of 10 and 12. Forty-six of the children's parents were divorced (hereafter called divorce children), and 44 of the children's parents were not divorced (hereafter called nondivorce children). Divorce children were interviewed after the testing. Nondivorce children were found to have firmer body boundaries (i.e., higher barrier and lower penetration scores) than divorce children. The quality of the child's relationship with the noncustodial father and the child's age at the time of separation were found to be related to the barrier score among boys but not among girls. The vulnerability of body boundaries appears to persist even years after the family breakup, indicating that for children of either sex the effects of divorce are long-term.     

Three-year analysis of characteristics of learning disabled students in self-contained classrooms and resource rooms

The present investigation examined the characteristics of school-identified learning disabled students from a large metropolitan school district in Tennessee. While it corroborated several findings of previous surveys of such students, this report also supplemented the literature by comparing the differences within a three-year span of time between school-identified learning disabled students who were assigned to self-contained classrooms and those who were assigned to resource rooms. Among the major findings were the presence of initial differences in IQ between self-contained and resource room students, the absence of differences in initial achievement scores between these two groups, and a decline over time in IQ, arithmetic, and spelling scores for both groups.     

General Newsletter

Low scores often have been ignored in validity research on the MMPI, yet these statistically significant deviations from the norm may be valuable sources of information and occur frequently enough to merit further investigation. The meaning of low scores on the MMPI-2 was examined for 822 male-female partner pairs in the MMPI-2 restandardization sample. Subjects were divided by MMPI-2 scale scores into high-, medium-, and low-score groups. Analyses of variance were performed with score level as the independent variable and partner ratings as dependent variables. Significant differences were found between the low- and medium-score groups with low scorers rated as better adjusted than medium scorers. More significant differences were found between the high-score and medium-score groups than between the low-score and medium-score groups; this suggested that high scores on MMPI-2 clinical scales are associated with poorer adjustment.

An exploration of adolescent emotional intelligence in relation to demographic characteristics

Emotional intelligence (EI) was measured in 200 youth ages 16-19. EI scores were compared to demographic characteristics of the individuals (age, sex, household income, parents' level of education, and location of residence). Findings indicate that EI levels were positively related to females, parents' education, and household income. The study did not show significant relationships between adolescent EI and location of residence or age. EI scores were significantly different between females and males, with females reporting higher EI levels. A one-way ANOVA showed no significant differences between EI scores and age, location of residence, and household income. Significant differences were found based upon EI scores for parents' education; as they increased, so did EI levels. In a linear regression model, with demograpics as the independent variables and EI as the dependent variable, father's education and sex were both predictors. The results will guide future studies to determine the factors behind adolescent El formation and development.     

An experimental analysis of delayed posttraumatic stress

Three self-report anxiety questionnaires were administered to a sample of Lebanese undergraduates shortly before the Israeli invasion of Lebanon in 1982. Six months after the disengagement of forces, the investigator located 20 Ss who had remained in West Beirut throughout the siege and 35 Ss who had evacuated to safer environs. The inventories were readministered to the Ss and the results revealed that: (1) there were no significant differences between the preinvasion scores of the evacuees and nonevacuees: (2) there were no significant differences between the postinvasion scores of the evacuees and nonevacuees: and (3) the aggregate scores of both groups vis-á-vis war-related stimuli were significantly lower at postassessment.     

Conformity behavior of Afrikaans- and English-speaking adolescents in South Africa.

The conformity behaviors of 50 Afrikaans- and 48 English-speaking early adolescents (ages 12 to 14 years) were measured by a modified Asch experiment and then compared. The effects of sex, self-concept (measured by the Tennessee Self-Concept Scale) and certain personality factors (measured by the High School Personality Questionnaire) were also examined. No significant differences between the conformity scores of the two groups were found, but boys and girls significantly differed with regard to their conformity scores. Although subjects with low self-concept scores did not have higher conformity scores than those with high self-concept scores, a significant difference between the self-concept scores of Afrikaans- and English-speaking adolescents was demonstrated. Low but significant correlations were found between personality factors (A, J, and Q2) and conformity scores.     

Relationship of scores on PPVT-R and WISC-R with special education children and youth

Comparisons of the Peabody Picture Vocabulary Test-Revised and the Wechsler Intelligence Scale for Children-Revised were made with 104 children diagnosed as learning disabled and mentally retarded. Significant but modest correlations were found between all but one of the WISC-R scaled scores (i.e., Coding) and PPVT-R standard scores, and between WISC-R IQs and PPVT-R standard scores. Significant differences were found among mean Verbal, Performance, and Full Scale IQs and mean PPVT-R standard scores. The PPVT-R standard scores underestimated WISC-R Verbal IQs by 7 points, WISC-R Performance IQs by 17 points, and WISC-R Full Scale IQs by 11 points.     

Effects of training intensity on observers' ratings of anxiety, social skills, and alcohol-specific coping skills

Few studies have addressed the amount of training needed to obtain reliable ratings in behavioral observation data. The current study examined the effects of differing intensities of frame-of-reference (FOR) rater training on observers' ratings of anxiety, social skills, and alcohol-specific coping skills in community volunteers with and without social anxiety and alcohol use disorders. Interrater reliability was assessed by comparing three training conditions (no-training, moderate FOR, and intensive FOR) on discrepancies between raters'scores and the strength of association between raters'scoring patterns. The discrepancies between raters' scores were significantly larger in the control condition than in the intensive and moderate training conditions. Generally, small and nonsignificant differences were found between intensive and moderate training's discrepancy scores. Strength of association results showed significantly lower correlations in the control group compared to the intensive group. However, these correlational results showed less consistent differences between the moderate and other training conditions; differences when found were in the expected directions. Study findings suggest that differing training intensities can affect rating scores and that interrater reliability may be meaningfully assessed through multiple methods.     

Gender and Grade Differences in Latent Ability Variables

Scores in ability tests administered to students in grades 4–9 were simultaneously factor-analyzed within twelve gender by grade groups. Gender and grade differences in means and variances were studied for five latent ability factors according to a hierarchical model and compared with means and variances in the observed scores.
Girls had higher means than boys in a general ability factor (G), in a residual general speed factor (Gs') and in a residual factor of numerical facility (N'). Boys were higher in a residual vocabulary factor (V') and most of all in a residual spatial visualization factor (Vz'). Boys had larger variances than girls in N' and Gs'. In general the differences in means and variances were in the same direction for the closest corresponding observed scores, but some striking discrepancies between latent and observed scores were found. As a rule, the discrepancies were due to the complexity of the tests where one factor could compensate for another.
In the discussion it was pointed out that some of the differences found were likely to have changed between the testing in the late 1950s and the present. Nevertheless the demonstration of the divergence between analyses of latent vs. observed scores remains valid.     

Conformity Behavior of Afrikaans-and English-Speaking Adolescents in South Africa

Abstract

The conformity behaviors of 50 Afrikaans- and 48 English-speaking early adolescents (ages 12 to 14 years) were measured by a modified Asch experiment and then compared. The effects of sex, self-concept (measured by the Tennessee Self-Concept Scale) and certain personality factors (measured by the High School Personality Questionnaire) were also examined. No significant differences between the conformity scores of the two groups were found, but boys and girls significantly differed with regard to their conformity scores. Although subjects with low self-concept scores did not have higher conformity scores than those with high self-concept scores, a significant difference between the self-concept scores of Afrikaans-and English-speaking adolescents was demonstrated. Low but significant correlations were found between personality factors (A, J, and Q2) and conformity scores.     

Intellectual similarities within families of both adopted and biological children

The effects of genetic and environmental differences on intellectual differences among children were examined in a study of families with both biological and adopted children. IQ scores of all family members and education of natural parents were used to estimate intellectual similarities among related and unrelated persons, living together and apart. Comparisons of correlations between related and unrelated siblings produced negligible heritability values, whereas the parent-child data suggested moderate heritability for the children's IQ differences. The high mean values of the adopted children's IQ scores and the high degree of similarity among unrelated sibs suggest that IQ scores are more maleable than previously thought.     

Physical fitness of South African primary school children, 6 to 13 years of age: discovery vitality health of the nation study

Basic physical fitness was measured using 8 different measures for 10,295 South African children and youths (5,611 boys, 4,684 girls) ages 6 to 13 years. These measurements included height, weight, Body Mass Index, standing long jump, shuttle run, sit-and-reach, sit-up (EUROFIT testing battery), and cricket ball throw scores. Due to the effects of earlier apartheid laws on separating communities, it was hypothesized that scores for different ethnic groups may differ. Therefore, in addition to the calculation of basic norms and sex differences, ethnic differences were also tested. Height and weight, relative to age, were different between the various ethnic groups (Black, White, and Mixed ancestry) for boys, with Black boys being shorter and lighter than White boys. There were no differences in sit-and-reach flexibility scores between the groups. With the exception of the cricket ball throw for girls, White children had higher scores in most tests. Although not significantly different from the White children, in the majority of cases, the children of mixed ancestral origin had scores that ranged between the other two ethnic groups. These results suggest a need for encouraging fitness in school children, and the reintroduction of formal physical education into the South African school curriculum, especially into schools in which Black children predominate.     

Leiter-3 generalizability in Scandinavia

The Leiter-3 is a nonverbal assessment that evaluates cognitive abilities and has been adapted for use in Scandinavia. Generalizability of United States-based normative scoring for use with the Scandinavian population was evaluated. Leiter-3 scores from a sample of Scandinavian students were compared with scores obtained from the Leiter-3 standardization sample, controlling for confounding variables, across ages, using mixed-methods analysis. A Scandinavian-population-based sample was created from Leiter-3 standardization data and norms were constructed and were used to generate standardized scores from the sample data. Results suggest that overall the Scandinavian test-takers score higher than American test-takers, but that differences between groups were minimized when controlling for factors that may influence cognitive performance. Creating Scandinavian based scores was not effective at reducing gaps in performance, suggesting that differences in performance between the different populations may be attributable to factors other than those typically controlled for when constructing standardized tests. Implications of these results and recommendations for Leiter-3 adaptation are reviewed.
