The etiology of behavioral problems and competencies in very young twins

Although genetic and environmental influences on behavior problems in middle childhood and adolescence have been well-studied, little is known about the etiology of behavior problems in very early childhood. The present study explores genetic and environmental contributions to individual differences in behavior problems and competences in an infant-toddler sample of twins. There were 1,950 twin pairs (mean age=23.8 months) who were rated by parents on the Infant-Toddler Social and Emotional Assessment. All four domains (Externalizing, Internalizing, Dysregulation, Competence) and 20 subscales-indices on the Infant-Toddler Social and Emotional Assessment displayed significant heritability. There were also substantial shared environmental influences operating on most of the domains and subscales. Compared with behavior problems, behavioral competencies were less heritable and more influenced by shared environments.     

The relationship of parental warm responsiveness and negativity to emerging behavior problems following traumatic brain injury in young children

Parenting behaviors play a critical role in the child's behavioral development, particularly for children with neurological deficits. This study examined the relationship of parental warm responsiveness and negativity to changes in behavior following traumatic brain injury (TBI) in young children relative to an age-matched cohort of children with orthopedic injuries (OI). It was hypothesized that responsive parenting would buffer the adverse effects of TBI on child behavior, whereas parental negativity would exacerbate these effects. Children, ages 3-7 years, hospitalized for TBI (n = 80) or OI (n = 113), were seen acutely and again 6 months later. Parent-child dyads were videotaped during free play. Parents completed behavior ratings (Child Behavior Checklist; T. M. Achenbach & L. A. Rescorla, 2001) at both visits, with baseline ratings reflecting preinjury behavior. Hypotheses were tested using multiple regression, with preinjury behavior ratings, race, income, child IQ, family functioning, and acute parental distress serving as covariates. Parental responsiveness and negativity had stronger associations with emerging externalizing behaviors and attention-deficit/hyperactivity disorder symptoms among children with severe TBI. Findings suggest that parenting quality may facilitate or impede behavioral recovery following early TBI. Interventions that increase positive parenting may partially ameliorate emerging behavior problems.     

The relationship of personality and behavioral development from adolescence to young adulthood and subsequent parenting behavior

The purpose of the study was to examine the association of parental personality, behavior, and substance use during adolescence and adulthood as related to the later parent-offspring relationship. The sample consisted of 297 parents (M age 32 yr.), who were first interviewed at earlier points in their lives in childhood and early adolescence at six points in time, extending from 1983 to 2002. Multiple regression models showed that parents with certain earlier personality and behavioral attributes, e.g., more rebelliousness and more frequent tobacco use, had a more difficult relationship with their children. Findings indicated an association between the cumulative number of psychosocial risk factors in the parents and difficulties in the parent-child relationship. The findings suggested that interventions designed to decrease youths' substance abuse may increase the likelihood that later when they are parents they will form nurturing relationships with their children.     

The structure and prevalence of behavioral problems in Hong Kong preschool children

Nearly all 3-year-old Chinese children in Hong Kong attend preschool facilities, making it possible to study their behavior in a group learning situation based upon teachers' perception. The Preschool Behavior Checklist (PBCL), a teacher's questionnaire, was applied to a random sample of 851 Chinese children, ages 36 to 48 months. The factor structure of the PBCL was very similar to that obtained from its original British study, supporting its usage cross-culturally. Prevalence of behavior disorder was high as defined by the PBCL. This reflected specific cultural demands at school settings. Significant sex differences were also found in the overall rate of behavior disorder and symptom patterns. As in other studies, boys had more hyperactive, conduct, and speech problems. The results suggested a certain degree of universality of symptomatology for children at the preschool level.This project was funded by the Hong Kong Society for Child Health and Development. We are grateful to all the kindergartens and child care centers which participated in this project. Valuable assistance was provided by the Education Department and the Medical Health Department.     

Test response inconsistency in young children

Five studies were conducted which indicated that young children show a high degree of inconsistency of response from test to retest. The first three studies included one in which the same concepts were measured on two different forms of a test of basic concepts given one day apart—one in which the same test was given prior to and following a 3-month intervention program, and one in which the same concepts were presented twice on the same test. Studies four and five employed standardized test items from the Stanford Binet, WPPSI and McCarthy Scales with retest intervals of approximately 3 months and 15 minutes, respectively. Results indicated that preschool children show a high degree of variability when responding to the same test questions even with a short time interval. In the first two studies, 90% to 100% of the children were inconsistent in responding. In the third study, one third of the children responded inconsistently. The last two studies with standardized test items revealed inconsistency of response among approximately 40% to over 80% of the children, depending upon the retest interval and the items examined. The studies highlight the need for those who evaluate educational programs and those who design tests to have a greater understanding of the manner in which young children perform in situations that are designed to demonstrate learning.     

The Animal Preference test and Its Relationship to Behavioral Problems in Young Children

We compared performance on the Animal Preference Test; (APT; Van Krevelen,, 1955) with parental assessment of children's behavioral problems as measured by the Achenbach Child Behavior Checklist (CCBL; Achenbach & Edelbrock, 1986). Forty Black and Hispanic 6- to 12-year-old boys were asked to name the three animals they would most like to be and the three animals they would least like to be if they could not be a human being. Reasons for animal choice were categorized into one of four theme categories: aggression, autonomy, nurturance, and pleasure-beauty. Each category had a high degree (91%) of interrater reliability. When reasons for animal choice were dichotomized into aggression/autonomy versus nurturance/pleasure-beauty, children who rejected animals because of their nurturant or aesthetic qualities displayed significantly greater aggressive (p < .001) and depressed (p < .05) behaviors on the CBCL. The choice of animals the subjects would most like to be was not meaningfully associated with CBCL performance. Further research with this easily administered and reliably scored projective test appears warranted.     

Novelty responding and behavioral development in young,developmentally delayed children

This study examined whether or not a measure of information processing ability based on the discrimination of novel and familiar stimuli was related to behavioral development among developmentally-delayed infants. Two samples of handicapped infants were administered multiple measures of visual novelty discrimination and a battery of assessments which were representative of available measures of development in infancy. The results indicated that, as a group, the developmentally delayed infants were capable of discriminating novel and familiar stimuli. Also, correlational analyses indicated that responding to novelty was related to developmental accessment performance in both samples. This finding is consistent with previous data which indicates that novelty response measures are associated with important individual differences in young children.     

Stereotypes versus behavioral judgments of sex differences in young children

Parents and child care workers were asked to rate 30 preschool child behaviors according to the cultural stereotypes concerning sex-typed behavior and actual behavioral differences between boys and girls. Both agreed on cultural stereotypes, with males rating more behaviors stereotyped than females. The behavioral ratings and cultural stereotypes of parents showed more agreement than those of child care workers. Parents overestimated sex differences in behavior, while child care workers underestimated them.This study was supported by a grant from the Office of Scientific and Scholarly Research, Graduate School, University of Oregon.     

A self-report typology of behavioral adjustment for young children

A large, national U.S. sample of children rated their own behavior and emotions using the Self-Report of Personality-Child version (SRP-C) of the Behavior Assessment System for Children (C. R. Reynolds & R. W. Kamphaus, 1992). Cluster analysis was used to group 4,981 self-reports (SRP-C) of children between the ages of 8 and 11 years. Theoretical and empirical considerations were used to identify a 10-cluster solution. Internal validation procedures revealed that the 10-cluster solution was well replicated by independently classifying 2 large subsamples of participants. External validation evidence revealed that only 2 of the 10 clusters could be differentiated by parent and teacher ratings of behavior problems. Peer ratings of social status and behavior, however, proved far better than adult ratings at differentiating the clusters. These findings suggest that the realm of intraindividual adjustment is not well understood by parents and teachers of these same children.     

The relationship variable in behavioral consultation

Behavioral consultation has traditionally been conceptualized as a scientific-technological exchange process where the primary goal is the transfer of information. Perceived reluctance of school personnel to use behavioral techniques has been seen as a special problem of educational settings. However, current understanding of this reluctance has emerged from the treatment adherence literature which stresses the complexity of adherence in clinical settings. One important issue which has emerged is the critical importance of the consultation relationship. While behavioral consultation has utilized an expert model focused on client behavior and problem solving, the efficacy of a more collaborative consultation style has been recommended. Behavioral consultants need to attend to factors such as communication strategies that facilitate shared responsibility as well as to understand consultees' explanations for their problems and their treatment expectations. Such skills need to be incorporated directly into the education of behavioral consultants along with behavioral technology if the behavioral model is to be disseminated widely into educational practice.     

The relationship between sleep problems and working memory in children born very preterm

In two studies, the relationship between sleep and working memory performance was investigated in children born very preterm (i.e., gestation less than 32 weeks) and the possible mechanisms underlying this relationship. In Study 1, parent-reported measures of snoring, night-time sleep quality, and daytime sleepiness were collected on 89 children born very preterm aged 6 to 7 years. The children completed a verbal working memory task, as well as measures of processing speed and verbal storage capacity. Night-time sleep quality was found to be associated with verbal working memory performance over and above the variance associated with individual differences in processing speed and storage capacity, suggesting that poor sleep may have an impact on the executive component of working memory. Snoring and daytime sleepiness were not found to be associated with working memory performance. Study 2 introduced a direct measure of executive functioning and examined whether sleep problems would differentially impact the executive functioning of children born very preterm relative to children born to term. Parent-reported sleep problems were collected on 43 children born very preterm and 48 children born to term (aged 6 to 9 years). Problematic sleep was found to adversely impact executive functioning in the very preterm group, while no effect of sleep was found in the control group. These findings implicate executive dysfunction as a possible mechanism by which problematic sleep adversely impacts upon cognition in children born very preterm, and suggest that sleep problems can increase the cognitive vulnerability already experienced by many of these children.     

Computer administration of the Peabody Picture Vocabulary Test to young children

Computer-controlled administration of the Peabody Picture Vocabulary Test to children between the ages of 4 and 13 years was shown to be feasible without the presence of a live examiner. Test-retest correlation coefficients were obtained in the range from .54 to .74 and were not significantly different from those obtained with manual administration in the PPVT standardization sample. Practice effects and IQ differences between the two forms of the test were nonsignificant.     

The use of biofeedback techniques with school-aged children exhibiting behavioral and/or learning problems

This article reviews 44 studies that investigated the efficacy of biofeedback techniques in treating childhood behavioral and learning disorders. Although the data suggest that children can learn voluntary control over a variety of physiological processes, methodological flaws make it impossible to specify the mechanisms responsible for such learning. Further, the data do not suggest that biofeedback techniques are superior to more conventional treatments in remediating learning or behavioral disorders. Suggestions for future research focus upon the elimination of methodological weaknesses, the use of more stringent diagnostic criteria, and the use of more sophisticated biofeedback equipment and procedures.     

Social competence and conduct problems in young children: issues in assessment

Examined the differences in various facets of social competence in 2 groups of young children (ages 4-7 years)--a clinic-referred group of aggressive children (N = 60) diagnosed with oppositional defiant disorder or conduct problems and a matched comparison group of typically developing children (N = 60). Four aspects of social competence were assessed: social information processing, actual observations of conflict management skills and social play interactions during peer interactions, positive social interactions with mothers and fathers at home, and teacher reports of social competence. The social information processing assessed included problem-solving skills (hypothetical skills as demonstrated on a social problem-solving test), self-perceptions (child's awareness of his or her own social self and feelings of loneliness), perceptions of others (attributions), and perceptions of others' attitudes toward oneself. To determine the construct validity of various means of assessing child social competence, we correlated children's social information processing measures with parent and teacher reports of social adjustment and with actual observations of interactions during peer play and at home with parents. Results comparing the 2 groups suggest that young children with conduct problems have deficits in their social information processing awareness or interpretation of social cues--they overestimate their own social competence and misattribute hostile intent to others. Tests of cognitive problem solving and observations of peer play interactions indicated that the children with conduct problems had significantly fewer positive problem-solving strategies and positive social skills, more negative conflict management strategies, and delayed play skills with peers than the comparison children. Correlation analyses indicated significant correlations between children's negative attributions and the ratio of positive to negative problem-solving strategies with observations of peer play interactions.     

The varieties of speech to young children

This article examines caregiver speech to young children. The authors obtained several measures of the speech used to children during early language development (14-30 months). For all measures, they found substantial variation across individuals and subgroups. Speech patterns vary with caregiver education, and the differences are maintained over time. While there are distinct levels of complexity for different caregivers, there is a common pattern of increase across age within the range that characterizes each educational group. Thus, caregiver speech exhibits both long-standing patterns of linguistic behavior and adjustment for the interlocutor. This information about the variability of speech by individual caregivers provides a framework for systematic study of the role of input in language acquisition.
