Executive Functions in Preschool Children with Aggressive Behavior: Impairments in Inhibitory Control

The question whether executive function (EF) deficits in children are associated with conduct problems remains controversial. Although the origins of aggressive behavior are to be found in early childhood, findings from EF studies in preschool children with aggressive behavior are inconsistent. The current study aimed to investigate whether preschool children with aggressive behavior show impairments in EF. From a population-based sample, 82 preschool children who were showing aggressive behavior as indicated by scores at or above the 93rd percentile on the Aggressive Behavior Scale of the CBCL 1 1/2-5 were selected. These children with aggressive behavior were matched on IQ to a group of typically developing control children (N = 99). Six neuropsychological tasks were administered to assess set shifting, inhibition, working memory and verbal fluency. A factor analysis was conducted which yielded one clear factor: inhibition. Aggressive preschool children showed poorer performance on this inhibition factor than control children and boys performed worse on this factor than girls. This association between aggressive behavior and inhibition deficits was maintained after controlling for attention problems. In addition, gender differences in all EFs measured were found with boys exhibiting more impairment in EF than girls. These findings demonstrate that preschool children with aggressive behavior show impairments in inhibition, irrespective of attention problems.     

Children with ADHD in Residential Care

Little is known about the characteristics or functioning of children with ADHD in residential care as compared to their non-ADHD peers. This study evaluated data on 538 children with (n = 125) and without (n = 413) ADHD in residential care to determine demographic, mental health, behavioral, and treatment (i.e., medication use) characteristics. Results revealed that both groups presented elevated risks, however, scores for children with ADHD indicated even greater levels of need. Specifically, differences were found between the two groups on demographics (e.g., family reunification status, restrictiveness of prior out-of-home placements), behavior (e.g., attention problems, rule-breaking and aggressive behaviors) and medication status. Findings suggest there is a need for aftercare services to help support families as children transition from care, interventions to address behavior, and medication management through assessment and monitoring.     

The Kent-Rosanoff Word Association: I. New Frequencies for Ages 18–21 and a Comparison with Kent-Rosanoff Frequencies

Imitative behavior was studied with the use of 36 kindergarten children who were either reinforced or not reinforced for imitative behavior prior to observing a male model exhibit aggressive behaviors. The children were tested for imitative aggressive behaviors in an eight-minute free-play situation, by means of a five-category rating scale. The results revealed that the reinforced group emitted significant more physical, verbal, and nonimitative aggression than the nonreinforced group. A second test examined the retention of the model's aggressive behavior under an incentive condition. The incentive condition diminished the initial differences found in the first test, revealing a nonsignificant difference between the reinforced and nonreinforced groups. Hence, the study provided support for both the “contiguity” and “generalized imitation” theories of social modeling.     

Sex-Typed Behavior in Preschoolers: Sex,Age, and Social Class Effects

Sex, age, and social class differences in the sex-role differentiation of preschoolers were investigated in the present study. Ss included 469 three-, four-, and five-year-old boys (N = 245) and girls (N = 224), sampled in approximately equal numbers from middle-and lower-income populations. Children were observed at three-week intervals in the naturalistic environment of their nursery school or daycare classrooms for occurrences of pcespecified aggressive, dependent, and cooperative (i.e., sex-typed) behaviors. A 2(Sex) x 3(Age) x 2(Social Class) ANOVA was performed on each behavior rate. Sex differences were found in the expected direction for aggression and dependency, but not cooperation. Age differences varied by sex, social class, and type of behavior. Social class effects were weakest, but significant for aggression and cooperation.     

Overt and covert antisocial behavior: Child and family characteristics among psychiatric inpatient children

The present study examined child and family characteristics associated with overt and covert antisocial child behaviors. Child psychiatric inpatients (N=258, ages 6–13) were identified as high in overt and/or covert antisocial behaviors (e.g., aggression and stealing, respectively) based on a structured parent interview measuring antisocial behavior. Children were classified into four groups derived from the factorial combination of level of overt (high vs. low) and covert (high vs. low) antisocial behaviors. Analyses were made of the children's reactions to hostile and anger-provoking situations, deviant and prosocial child behaviors at home and at school, and family structure and organization. Children higher in overt antisocial behaviors were more negative, resentful, and irritable in their reactions to hostile situations and more aggressive at school. They came from families with significantly greater conflict and less independence among family members. Children higher in covert antisocial behavior participated in fewer social activities and were higher in anxiety; their families showed significantly lower family cohesion and organization and less of an emphasis on moral-religious values. The results suggest reliable differences in child and family functioning as a function of patterns of overt and covert antisocial behavior.     

Mother-child interactions in ADHD and comparison boys: Relationships with overt and covert externalizing behavior

Reciprocal relationships between child characteristics and such familial factors as parental psychopathology and interaction style with the child characterize the development and maintenance of attention-deficit hyperactivity disorder (ADHD) as well as its comorbidity with antisocial behavior. Our goal was to ascertain the ability of negative maternal behavior exhibited during mothers-on interactions to predict independently observed overt and covert externalizing behavior in the child, controlling for current maternal symptomatology and the boy's acting out behavior during the interaction. Participants were 49 boys with ADHD and 37 comparison boys, aged 6 to 12 years. Hierarchical multiple-regression analyses revealed that, even with maternal psychopathology and child negativity with the mother partialed, maternal negative behaviors predicted both observed noncompliance exhibited in class and play settings and laboratory stealing. Stealing was predicted from maternal negativity even with child interactional compliance controlled. Differential predictions of noncompliance were revealed in ADHD versus comparison families, yet similar patterns emerged for stealing within each group. Results are discussed in light of the high risk for antisocial behavior in ADHD children.This article is based, in part, on a doctoral dissertation written by Carolyn A. Anderson at the University of California, Los Angeles. The research received primary support from National Institute of Mental Health Grant 45064, awarded to Stephen P. Hinshaw.

In Protection of Ourselves: Black Girls' Perceptions of Self-Reported Delinquent Behaviors

The purpose of this study was to explore Black adolescent girls' perceptions of self-reported delinquent behaviors. Semi-structured interviews were conducted with 11 Black girls enrolled in alternative schools designated for "delinquent" adolescents. Using dimensional analysis, two general categories emerged from the data: defending/protecting self and self-interest. All of the girls indicated that they used aggressive behaviors to protect themselves from perceived threats. Generally, the girls protected themselves using two strategies: "Hold off" strategies were used to avoid physical and/or verbal conflicts, and "face down" strategies were used to physically confront threats. To a lesser degree, girls discussed gaining materially from specific behaviors ( e.g., stealing and lying). One important implication of this research study is that aggressive Black girls may often perceive their environment to be hostile and nonsupportive. Consequently, support needs to be provided for Black girls who engage in aggressive behaviors.     

The incidence,prevalence, and severity of behavior disorders among preschool-aged children in day care

This study examined the incidence, prevalence, and severity of 14 empirically derived externalizing (unsocialized aggressive) and internalizing (socially withdrawn) behaviors among 2- through 5-year-olds attending day care. Teacher ratings were obtained for 558 children in the incidence sample and 709 children in the expanded prevalence sample. Within each age, data were cross-tabulated by sex of child and severity of behavior, and chi-square analyses were computed. Results indicated that a substantial proportion of children in the normal preschool population exhibit relatively high severities of selected externalizing and internalizing behaviors; this proportion varied with the age of the child and the behavior rated. Preschool-aged boys were consistently rated as demonstrating greater frequencies of externalizing behaviors than preschool-aged girls. The diagnostic and clinical implications of these findings are discussed.     

Brief report: Non-intrusive operant analysis of aggressive behavior in persons with mental retardation

A procedure for operant analysis of aggressive behavior was derived from multi-element assessment methods that have been previously applied to both self-injurious and stereotypic responding. Analog sessions included No Interaction Baseline, Social Disapproval, Demand, Social Reinforcement, and Discriminated Extinction conditions, repeatedly presented within a multi-element design. Three men with differing severity of mental retardation, communicative deficits and aggressive behavior were exposed to multiple brief analog sessions embedded within their normal meal-time routines in group home settings. Mean frequencies of aggressive behavior and concurrent eating indicate that, while aggressive behavior was negatively reinforced in all three participants, both social and non-social contingencies were also prominent. The same contingencies which have been demonstrated to maintain self-injury and stereotypic behavior can therefore also maintain aggression. Results suggest the feasibility of conducting relatively non-intrusive analog assessments in community residences, and support the-extension of functional analysis across differing classes of aberrant behavior.     

Direct Social Support for Young High Risk Children: Relations with Behavioral and Emotional Outcomes across Time

This study is unique in addressing developmental correlates of direct social support for young children in a high risk sample, in contrast to previous studies addressing social support for caregivers. Participants were drawn from a prospective, longitudinal study of at-risk children. Social support was rated from maternal interviews throughout early childhood. Support from the mother was assessed from mother-child observations. Outcomes included internalizing and externalizing behavior problems measured from first through tenth grades. The most common support providers were biological fathers, followed by grandparents and other providers. Using multilevel modeling, higher quantity, higher quality, and lower disruption of support predicted lower starting levels of behavior problems, controlling for support from the mother. Disruption was associated with change in slope. Gender differences were found for externalizing behavior intercepts. Social support provides a promotive factor for young high risk children. Implications include involving children's social support providers in prevention and intervention programs.     

Empirical evidence for overt and covert patterns of antisocial conduct problems: A metaanalysis

Twenty-eight factor- and cluster-analytic studies of child psychopathology were examined for patterns in antisocial behavior. A multidimensional scaling analysis yielded one dimension that was labeled overt-covert antisocial behavior. One end of this dimension consisted of overt or confrontive antisocial behaviors such as arguing, temper tantrums, and fighting. The other end consisted of covert or concealed antisocial behaviors such as stealing, truancy, and fire setting. Implications derived from the present findings are discussed as they apply to the diagnosis, prevention, and treatment of antisocial behaviors in children.The authors are indebted to Drs. C.

Reducing the Risk for Preschool Expulsion: Mental Health Consultation for Young Children with Challenging Behaviors

Increasing numbers of young children are being expelled from child care settings because of their problem behavior. Access to mental health consultation is related to lower rates of expulsion, but additional data are needed to document the pathways through which mental health consultation reduces the risk of expulsion. We report on outcomes from a 4-year project designed to reduce the number of children expelled for problem behavior in a large suburban county in Maryland. Two master’s-level professionals provided behavioral consultation to child care providers who identified nearly 200 children at imminent risk for expulsion. Child care providers rated children’s social skills and problem behaviors at referral and discharge using the Preschool Kindergarten Behavior Scales and the Brief Infant Toddler Social Emotional Assessment. Statistically significant increases in social skills and reductions in problem behaviors were seen for children who received individualized consultation. More than three-quarters of the children who were at risk for expulsion were able to be maintained in their current child care placement; of those that changed placements, only half (n = 13) were removed involuntarily. These findings provide additional support for mental health consultation as a promising strategy to reduce the risk for expulsion for young children with problem behaviors.     

SOLITARY TOY PLAY AND TIME OUT: A FAMILY TREATMENT PACKAGE FOR CHILDREN WITH AGGRESSIVE AND OPPOSITIONAL BEHAVIOR

The behavior of four boys, 5 to 8 years of age, who were referred for a number of oppositional, rule violating, and aggressive behaviors, was assessed by direct observation and parent reports. Following baseline measurement, several interventions were successively applied to each child's behavior. Use of a social play contract to reduce problem behaviors by teaching appropriate social behaviors resulted either in no improvement or in worsening of the problem behaviors in observations made when the contract was not in effect. Changing the contract behavior to solitary toy play resulted in reduced oppositional behavior during the observation sessions, fewer reports from the parents of low-rate problem behaviors, and improvements in the parents' attitudes toward the children. However, these changes during the observation sessions were shortlived, because the data on these measures began to show a reversal during later sessions. Inclusion of a time-out contingency with the solitary play contract recovered the earlier improvements in the children's behavior during observation sessions and the parents' reports. These results gave support to the view that for children whose behavior is severely oppositional and aggressive, a treatment approach emphasizing productive, solitary behaviors may be superior to one stressing appropriate social interaction. However, a combined strategy of reinforcement for solitary play and punishment for problem behaviors appears necessary to ensure more durable treatment effects.     

Multidimensional latent-construct analysis of children's social information processing patterns: correlations with aggressive behavior problems

Social information processing (SIP) patterns were conceptualized in orthogonal domains of process and context and measured through responses to hypothetical vignettes in a stratified sample of 387 children (50% boys; 49% minority) from 4 geographical sites followed from kindergarten through 3rd grade. Multidimensional, latent-construct, confirmatory factor analyses supported the within-construct internal consistency, cross-construct discrimination, and multidimensionality of SIP patterns. Contrasts among nested structural equation models indicated that SIP constructs significantly predicted children's aggressive behavior problems as measured by later teacher reports. The findings support the multidimensional construct validity of children's social cognitive patterns and the relevance of SIP patterns in children's aggressive behavior problems.     

The effects of video game play on young children's aggression, fantasy, and prosocial behavior

From the ecological perspective of human development the emergence of significant media may affect children's behavior. It has been suggested that the home computer has the potential to affect young children's behavior, but no published data currently exist to support this hypothesis. However, home computer games have features similar to television. In that vein, research on television and aggression lends itself as a paradigm for studying the effects of video games on young children's behavior. From past television research it may be hypothesized that exposure to violent video games will increase children's aggressive behavior. Twenty-eight children, age 4 to 6 years were observed in a free play setting at baseline, after watching a violent cartoon and after playing “Space Invaders”. Results indicated significant differences in aggressive behavior, relative to baseline behaviors, after watching television and after playing video games. There was no difference between the television and video game conditions. It was concluded that violent video games arouse children in much the same way as violent television cartoons.     

Interpersonal antecedents of drivers' aggression

The theory of social information processing, which suggests that attributions affect aggressive reactions to another person's provocative behavior, was applied to the context of driving. Respondents were 150 male drivers, who were presented with three scenarios describing frustrating driving situations caused by another driver, male or female. Hostile and non-hostile attributions, and the preference for either aggressive or non-aggressive reactions were measured for each scenario. Aggregate image of drivers as well as driving-related emotions were also measured. A path analysis showed that irritability and competitiveness mediate the relationship between aggressive reactions, on the one hand, and hostility, anxiety, and drivers' image, on the other. Hostile attributions were found to be directed more toward male than toward female drivers and were related to a negative image of drivers. The results are discussed with regard to interpersonal aspects of driving behavior.     

Child behavior disorders by age and sex based on item factoring of the revised Bristol Guides

Standardized teacher observations of 2,527 schoolchildren, selected at random for the revised Bristol Social Adjustment Guides were partitioned into four subsamples consisting of 797 5- to 10-year-old boys, 758 5- to 10-year-old-girls; 508 11- to 15-year-old boys, and 464 11- to 15-year-old girls, respectively. The children were observed by over 900 teachers and rated on 104 indicators of maladaptive behavior. Item scores for each age/ sex sample were subjected to first- and second-order factor analysis, with varimax rotation yielding identical second-order models of behavior disorder across age and sex samples and somewhat different first-order models for each sample. Comparison of derived dimensions with dimensions emergent in other behavior problem research indicated considerable consistency. Moreover, the similarity of the factorially derived dimensions confirmed the cross-age and -sex generality of the syndromes known as unforthcomingness, hostility, and depression, and provided reasonable support for the utility of the syndrome of inconsequence, although it was apparent that inconsequence stands as more a composite of underlying factor dimensions reflecting hyperactive and attention-seeking behaviors. While the withdrawal syndrome found factorial support, its integrity was clearly specific to child age and sex.     

A multitrait-multimethod analysis of the preschool behavior questionnaire

The Preschool Behavior Questionnaire is a teacher rating instrument yielding a total score reflecting overall level of adjustment and three subscale scores labeled Hostile/Aggressive, Anxious/Fearful, and Hyperactive/Distractible. This study assessed the convergent and discriminant validity of this teacher rating measure against two alternative measures within a multitrait-multimethod analysis. The results supported the construct validity of the Hostile/Aggressive and Anxious/Fearful scores as well as the overall score. There was, however, no support for the validity of the Hyperactive/Distractible score.This research was supported, in part, by a grant from the Pickering Foundation. The authors would like to thank Maria Bhaneja for her help in the collection and coding of data. Thanks are also extended to the teachers and children who participated in the study.     

Angry and aggressive behavior across three generations: a prospective,longitudinal study of parents and children

This investigation examined intergenerational continuities in both angry, aggressive parenting and also the angry, aggressive behavior of children and adolescents. Data from 75 G2 youth (26 men, 49 women, M = 22-years old), their mothers (G1), and their G3 children (47 boys, 28 girls, M = 2.4-years old) were included in the analyses. The prospective, longitudinal design of the study, which included observational and multiinformant measures, overcame many of the methodological limitations found in much of the earlier research on intergenerational transmission. The results demonstrated a direct connection between observed G1 aggressive parenting and observed G2 aggressive parenting from 5 to 7 years later. G2 aggressive behavior as an adolescent and G3 aggressive behavior as a child were related to parenting behavior but not directly to one another. The results were consistent with a social learning perspective on intergenerational continuities in angry and aggressive behaviors.     

Aggressive behavior in children's dolls' house play

The present study addressed the question of whether there are gender and age differences in aggressive behavior when it is studied as the spontaneous expression of mental contents and not as the result of immediate social interaction. This study also investigated whether aggression, in terms of mental content, is related to temperamental aspects. Aggressive behaviors were examined in make‐believe play, in relation to age, gender, and temperament in a near‐ecological context, i.e., the Dolls' House Play. The participants, 55 boys and 47 girls, subdivided into three age levels (4 years–4 years and 6 months; 5–6 years; and 7 years and 6 months–8 years and 6 months) were requested to represent what happens in their family 1) during Mealtimes; 2) at Bedtime; 3) on the Saddest day; and 4) the Happiest day; their Dolls' House Play was then recorded. Children's temperaments were measured with the TABC‐Teachers' form [Martin, The Temperament Assessment Battery for Children, Brandon, VT: Clinical Psychology Publishing, 1998]. Data analysis was conducted considering aggressive behaviors in their distinct expressions—physical, verbal, direct, and indirect. Results revealed no statistical differences between boys and girls when all aggressive behaviors were compounded. However, when the distinct types of aggressiveness were considered, boys presented statistically higher levels of physical aggression than girls did. Moreover, boys and girls reacted with different types of aggression in the different emotional contexts created by the four episodes. Few age differences were observed. Surprisingly, there was a significantly greater presence of indirect verbal aggressiveness in younger children. With respect to temperament, a higher level of negative emotivity was significantly linked to a greater degree of aggressive behaviors in some of the episodes. In conclusion, this paper confirms gender differences in the type of aggressive behavior children display even in the absence of any immediate social interaction, which might itself trigger aggression.
