Assessing Type A behavior in children: a longitudinal exploration of the overlap between Type A behavior and hyperactivity

Child Type A behavior and its relation to hyperactivity were investigated developmentally using a longitudinal normal sample of 91 children (46 boys and 45 girls) between the ages of 4 and 8-9. In light of the overlap found in several studies between Type A behavior, as measured by the Matthews Youth Test for Health (MYTH) questionnaire, and hyperactivity measured by questionnaires, an attempt was made to measure Type A behavior as distinct from hyperactivity using behavioral observations. The MYTH questionnaire and behavioral observations were used to assess Type A behavior and questionnaire-based measures and behavioral observations were used to assess hyperactivity. Predictions were made regarding individual stability in phenomena and in measures. The results indicated considerable stability in the respective Type A and hyperactivity measures over time, and further, that behavioral observations make it possible to measure Global Type A behavior and Type A Competitiveness as distinct from hyperactivity, although the status of Type A Impatience at early ages is not yet settled. The MYTH and the observed Type A behavior showed differential relations to external criteria, such as achievement measures and problem behavior. This has implications for future measurement and perhaps conceptualization of Type A behavior in children, and thereby also for studying the developmental aspects of Type A behavior.     

Early disruptive behavior,IQ, and later school achievement and delinquent behavior

A series of structural equation models is developed to examine the relationship between early externalizing behaviors (conduct problems, attention deficit) and IQ measured at age 8 years, academic achievement over the period 10 to 13 years, and delinquent behavior to the age of 15 in a birth cohort of New Zealand children. These models indicated that early externalizing behaviors and IQ were related to later academic achievement and delinquent behavior by two quite distinct but highly correlated developmental sequences. In one sequence early conduct problems were predictive of later delinquency but were not directly related to later academic achievement. In the other sequence, attention deficit and IQ were prognostic of later school achievement but were not directly related to delinquency. Further, the apparent correlations between academic achievement and delinquency were adequately explained by the common and correlated effects of early behavior and IQ on later achievement and delinquency. These conclusions remained unchanged when the sample was stratified by gender, and when further explanatory factors were introduced into the model.This research was funded by grants from the Health Research Council of New Zealand, the Canterbury Medical Research Foundation and the National Child Health Research Foundation.     

The relationship of three measures of childhood depression to academic underachievement

Clinical features of depression (short attention span, lethargy, poor memory and shortened task persistence) appear to be incompatible with effective learning. This has led several investigators to suggest that depression is a significant cause of academic underachievement. The most adequate test of this hypothesis (Tesiny, Lefkowitz, & Gordon, 1980), however, found only small correlations between depression and academic achievement when neither IQ nor socioeconomic status were controlled. In the present study, three measures of childhood depression (Peer Nomination Inventory for Depression, Children's Depression Inventory, and an ad hoc teacher rating) were correlated with scores from the Peabody Individual Achievement Test and the Stanford Achievement Test. IQ was statistically controlled to provide a direct measure of underachievement and analyses were conducted separately for males, females, and the combined sample in a sample that was homogeneous for socioeconomic status. Although intercorrelations among the variables indicated that the sample was appropriate to test the hypothesis, only a few significant correlations were found. These findings suggest that if depression causes academic underachievement, it is a weak or uncommon effect.     

The heritability of conscientiousness facets and their relationship to IQ and academic achievement

The heritability of conscientiousness has been one of the least explored of the NEO PI domains. Here we focus on the facet scales of the conscientiousness domain, estimating both their heritability and their correlations with measures of IQ and academic achievement (Queensland Core Skills Test; QCST) in a sample of adolescent twins and their non-twin siblings. Our findings confirmed positive associations between IQ and the facets of Competence and Dutifulness (ranging 0.11–0.27), with academic achievement showing correlations of 0.27 and 0.15 with these same facets and 0.15 with Deliberation. All conscientiousness facets were influenced by genes (broad sense heritabilities ranging 0.18–0.49) and unique environment, but common environment was judged unimportant. A multivariate genetic analysis including Competence, Dutifulness, IQ (verbal, performance) and QCST scores showed that common variance was primarily explained by a general additive genetic factor (loadings ranging 0.15–0.84). Future multivariate genetic analysis which incorporates Openness to Experience dimensions may improve the interpretation of these findings.     

Differentiating Type A behaviour and hyperactivity using observed motivation during a reaction time task

In light of the previously found overlap between Type A behaviour as measured by the Matthews Youth Test for Health (MYTH) and hyperactivity scales, the overall aim of this study was to clarify the standing of MYTH‐defined Type A behaviour relative to hyperactivity and Attention‐Deficit/Hyperactivity Disorder (ADHD), using observed task motivation and performance on a choice reaction‐time task, the Complex Reaction Time (CRT) measure. This study included 21 boys exhibiting Type A behaviour, 22 ADHD boys, 20 non‐clinically hyperactive boys, and 20 non‐hyperactive boys, between the ages of 6 and 13 years. It was proposed that a differentiation of constructs would be possible using observed task motivation if the MYTH were a discriminantly valid measure of Type A behaviour. Results showed that the MYTH‐defined Type A group differed from the clinically diagnosed ADHD group, although it was markedly similar to the non‐clinical hyperactive group, displaying comparable CRT performance and low level of task motivation. Type A behaviour correlated to CRT performance and task motivation in a way which was conceptually more indicative of hyperactivity than of Type A behaviour, which questions the validity of the MYTH as a measure of the Type A construct. The MYTH Impatience subscale was found to be particularly impure with regard to hyperactivity. Copyright © 2003 John Wiley & Sons, Ltd.     

Assessment of children's Type A behavior: relationship with negative behavioral characteristics and children and teacher demographic characteristics

Thirty-two teachers rated Type A behavior, using Matthews Youth Test for Health, (MYTH) and negative characteristics of hyperactivity, negative peer relations, social withdrawal, and depression in 105 children, between the ages of 6 and 11, from lower to middle class Black and White families. Children's age, gender, race, and socioeconomic status (SES) and teachers' gender, grade taught, and years of teaching experience were not related to teachers' MYTH ratings. However, White teachers rated children higher on Type A behavior than Black teachers. Controlling for teacher race effects, MYTH total scores, rather than reflecting a global negative view of the child, showed a strong overlap with hyperactivity and were differentiated from social withdrawal and depression. The MYTH Impatience/Aggression factor was highly related to hyperactivity and negative peer interactions; the Competitiveness factor was associated with a lack of social withdrawal. The conclusions verify the multidimensional nature of children's Type A behavior pattern and the importance of rater demographic characteristics in the assessment of children's behavior.     

Comparison of the Matthews Youth Test for Health and the Hunter-Wolf A-B Rating Scale: measures of type A behavior in children

This study evaluated the extent to which two youth measures of Type A behavior--the Matthews Youth Test for Health (MYTH) and the Hunter-Wolf A-B Rating Scale--similarly assess the Type A construct. Data from 25 elementary teachers and from 300 of their students revealed that these scales are weakly correlated and that the concordance of their Type A-Type B classifications was only slightly above that expected by chance. Weak agreement was found even when teachers and students rated the same Type A behaviors, which suggests that variability in content was not the principal reason for the lack of agreement between these measures. The major implication of this study is that the MYTH and the Hunter-Wolf scale should not be considered interchangeable measures of Type A behavior. The study reveals that investigators' choice of a Type A measure may strongly affect the nature of their research findings and may inhibit the integration of their data with data from other investigators who employ different measures of the Type A construct. It is recommended that, if multiple measures cannot be used in a study, the investigator employ the MYTH.     

Genetic and environmental influences on academic achievement trajectories during adolescence

Most studies have considered the effects of particular characteristics on academic achievement individually, which means that little is known about how they function together. Using the population-based Minnesota Twin Family Study, the authors investigated the effects of child academic engagement (interest, involvement, effort), IQ, depression, externalizing behavior, and family environmental risk on academic achievement (reported school grades) from ages 11 through 17. Hierarchical linear growth curve modeling showed main effects on initial reported Grades for all variables, and IQ mitigated the deleterious effects of family risk and externalizing. Only engagement affected change in Grades through adolescence. Influences on initial Grades were strongly genetically influenced, associated primarily with IQ, engagement, and externalizing behavior. Shared environmental influences on initial Grades linked engagement, IQ, and family risk. Genetic influences on change in Grades were substantial, but they were not associated with the academic, family risk, and mental health covarying factors. These results indicate that age 11 achievement and change in achievement through adolescence show systematic patterns and document the existence of individual differences in the commonly shared developmental experience of adapting to the school environment.     

Temperament,classmate likability,and social perspective coordination as correlates of children's parent-rated type A behaviors

Parents of 58 boys and 62 girls from grades three through eight completed the Matthews Youth Test for Health (MYTH), a measure of Type A behavior. Normative and reliability data were similar to those obtained from teachers as reported in the literature, but a factor analysis of parents' ratings revealed four factors (Competitiveness, Irritability, Impatience, and Leadership) as opposed to the two factors (Impatience/Aggression and Competitiveness) that have been derived from teacher ratings. Boys had higher total MYTH scores than girls, but correlations with age were not significant. No grade or gender effects were obtained for any of the four MYTH factor scores. Correlates of the MYTH scores were computed separately for boys and for girls. For boys, Irritability was related to Reactivity, a Difficult Temperament, low classmate Likeability, and poor performance on two social cognitive tasks (compromising and friendship understanding). For girls, Leadership was related to Classmate Likeability and good performance on the two social cognitive tasks. For boys only, total MYTH scores were related to low Attention Span, high Reactivity, a Difficult Temperament, and low Friendship Understanding scores. Findings are related to the gender differences found in the study of both ego control and cooperation/ competition.     

Relation of personality dimensions to social and intellectual factors in children

In the course of the Hungarian adaptation of the JEPQ, using 2185 children, aged 7–15, the relation of the personality dimensions E, N, P, L to academic achievement, school marks for ‘behaviour’ and ‘diligence’, IQ, size of settlement, education and occupation of father and mother was investigated. High academic achievement was found to be associated with E, Emotional Stability, low P and low L scores. High IQ and high marks for ‘behaviour’ and ‘diligence’ were found to correlate with Emotional Stability and low P. Children from smaller settlements and from lower-status background were more introverted, had higher P scores, were more labile, and had higher L score means, than those from larger settlements and high-status families.

Achievement and adjustment correlates of the matching familiar figures test

To help clarify the relationship between the Matching Familiar Figures (MFF) Test and measures of school achievement and adjustment, 450 children from kindergarten, second, and fifth grades were tested and achievement scores and teacher's ratings of classroom and personal adjustment were obtained. Regardless of grades, MFF latency in most instances did not predict achievement or adjustment. At the kindergarten level the correlations between MFF errors and both achievement and adjustment were significant for most subscales but at second grade correlations were lower and generally nonsignificant except for a few adjustment items. At the fifth grade level the correlations were moderately high but when IQ was partialled out the correlations with achievement and school adjustment dropped to near zero; however, partialling out IQ did not affect the moderate correlations between errors and personal adjustment. The errors score evidencedmore important relationships than the latency scores. The relationship between the MFF and ratings of social and emotional adjustment was consistently higher than the correlations between the MFF and achievement. These results suggest that MFF errors are personalogically relevant and that MFF performance is generally more related to adjustment than achievement.     

The type A behavior pattern in children: relationships with performance on speed oriented tasks

The Matthews Youth Test for Health (MYTH) was completed by teachers to evaluate 85 fifth- and sixth-grade boys. Type A and B groups of 20 boys each were selected based on MYTH scores. Each boy performed a signalled reaction time task and a perceptual search task. No performance difference was found between the Type A and B boys on the reaction time task. On the perceptual search task, each boy had to scan a set of pictures and report the number of "Snoopy's" seen in each picture. A group difference in response time was found, with the Type A boys having a mean of 5.98 s versus 7.87 for the Type B boys.     

Parental child-rearing attitudes associated with Type A behaviors in children

The relation of Type A behaviors to parental child-rearing attitudes was assessed for 177 mothers, 153 fathers, and their children in preschools. Type A behaviors of children were measured on the Japanese version of the Matthews Youth Test for Health (MYTH), and parental child-rearing attitudes were measured on the Parents' Attitudes Test (PAT). Children were classified as Type A and Type B on the basis of their MYTH scores, and parental child-rearing attitudes in the two types were compared in a combination of parental sex (mothers vs fathers) and child's sex (boys vs girls). Analysis showed that especially mothers and fathers of Type A boys had less concern for their children than their peers whose boys were classified as Type B. The notion that boys showing Type A behaviors might develop Type A behavior patterns by striving to obtain more expression of concern or affection from their parents was presented.     

A Latent-Variable Modeling Approach to Assessing Reliability and Validity of a Creativity Instrument

ABSTRACT: A multiple-choice paper-and-pencil test was developed based on the constructs from the Torrance Test of Creative Thinking (TTCT). The rationale of this new instrument was to shorten the amount of time required for the administration and scoring of creativity tests. This instrument was translated into Spanish and administered along with the TTCT and the Villa and Auzmendi Creativity Test (VAT) to 2,270 students in Spain. Teachers' ratings of student creativity were also obtained. Using a traditional concurrent validation approach from an earlier study, we found low but significant correlations between the scores of the four subscales of the new test and the same subscales of the VAT and TTCT, as well as the students' academic achievement measures. In terms of reliability, mostly moderate (internal consistency) reliability coefficients were found for the new test. As an alternative to the traditional approach, this study employed structural equation modeling (SEM) with multiple indicators to examine the validity and reliability of the new creativity test. The results indicated that substantial improvements in the validity and reliability estimation over the traditional approaches can be made by using SEM with multiple indicators.     

Impact of cognitive profile on social functioning in prepubescent females with Turner syndrome

Social deficits are prevalent in Turner syndrome (TS); however, the extent to which these difficulties are secondary to characteristic cognitive impairments is not well known. Here, we sought to establish the relative contribution of executive functions, visuospatial abilities, and IQ to social difficulties in young girls with TS. Forty TS girls and 19 typically developing (TD) children were assessed with the Social Responsiveness Scale (SRS), the Motor-Free Visual Spatial Test (MVPT-3), the Behavior Rating Inventory of Executive Function (BRIEF), and an IQ test. Hierarchical multiple regression analyses were conducted with the SRS subscales as outcome variables. In a first step, the cognitive factors were entered (verbal IQ, BRIEF global score, MVPT-3, and age), followed by the group variable in a second step. In comparison to TD, TS participants were significantly impaired on all main measures. All six regression models with the SRS subscales were significant and revealed that global executive functions explained the largest portion of the variance on all subscales and the total score. Even after controlling for cognitive elements, the group factor still explained a significant portion of the variance of the Social Cognition, Social Awareness, and Autistic Mannerisms subscales. In contrast, the group factor was not a significant predictor of Social Motivation and Social Communication scores. These results suggest that executive dysfunctions play a role in social impairments encountered in TS, but also that some specific aspects of social behavior are altered beyond what can be attributed to cognitive difficulties in this population.     

Black adolescents: a descriptive study of their self-concepts and academic achievement

This study was designed to determine the relationships among global self-concept, self-concept of academic ability, and academic achievement of black American adolescents. The subjects were 211 tenth-grade students in five public high schools in the Pacific Northwest school district who volunteered to participate in the study. Global self-concept was measured by the Coopersmith Self-Esteem Inventory (SEI), self-concept of academic ability by the Brookover Self-Concept of Ability (General) Scale, and academic achievement by the California Achievement Test (CAT). The major statistical tools were the Pearson product-moment correlations and Fisher Z statistic. In all of the tests the decision was made to reject the null hypothesis at the .05 level of significance. No significant relationship was found between global self-concept and academic achievement, although the relationship between self-concept of academic ability and academic achievement reached significance. The relationship between self-concept of academic ability and academic achievement correlated more strongly than the relationship between global self-concept and academic achievement. These results suggest that the enhancement of global self-concept might not be a potent intervention for academic improvement for black adolescents.     

Validity of the miami structured interview-1 for assessing type a behavior,competitiveness, and aggression in children

The validity of the Miami Structured Interview-1 for measuring Type A behavior in children was examined in 122 boys 8 to 16 years old. We assessed the relationship between interview ratings and Type A and factor analytically derived Type A component scores from the Matthews Youth Test for Health (MYTH), a teacher rating scale. The validity of interview ratings was initially supported by significant correlations with MYTH Type A scores for preadolescents rated by English teachers and adolescents rated by English and mathematics teachers. Principal-components analyses of the MYTH items revealed components we labeled competitiveness-leadership and impatience-aggression. Interview ratings were related to the competitiveness-leadership component from English and mathematics teachers of both age groups but not the impatience-aggression component. The implications of these findings and the strengths and limitations of the Miami Structured Interview-1 for preadolscents and adolescents are discussed.An earlier version of this paper was presented at the American Psychological Association 91st Annual Meeting, Anaheim, California, 1983.

Longitudinal Behavioral and Academic Adjustment in Children with HIV Infection

This study investigated; the behavioral adjustment and academic status of children with HIV infection through serial evaluations over a ten-year period. The parents of children were assessed with Achenbach Child Behavior Checklist Parent Forms and the children were administered the Woodcock-Johnson Tests of Academic Achievement at regular intervals as part of their treatment in the HIV Program of a children’s hospital. Children with HIV were found to have behavioral adjustment within normal limits over time. Aggressive behavior was noted to decrease over time. Academic achievement mirrored IQ status, unlike other studies, which have reported poorer achievement than expected for IQ. Math skills appeared to improve over time. Thus, these findings suggest children with HIV infection did not show significant behavioral disturbance across time, however, aggressive behavior appeared to decrease. Academic achievement was stable over time.
