Type A behavior in preschool children

Type A behaviors were observed in a group of 48 preschool children in different free-play and competitive situations. Interrater reliability was assessed on the Matthews Youth Test for Health (MYTH), and the children's and their parents' type A scores were compared. Scores on the MYTH were used to classify children as either type A or type B. Comparisons were made between type A and type B children's play in classroom and in laboratory situations. For the laboratory situations, 24 same-sex type A-type B dyads were formed, and the dyads were observed in free play, followed by car racing, by a tower-building contest, and by an interview. Type A children more frequently showed annoyed facial expressions, gross motor activity, interruptions during classroom free play, and gross motor activity and aggressive play with an inflatable Bobo doll during the laboratory free-play situation. Type A children more often won the car race and the tower-building contest, and they answered a greater number of questions and more frequently answered first during the interviews. These data are consistent with other findings on type A behavior in preschool children and suggest that the behavioral dimensions of type A (competitiveness and impatience-aggression) may emerge as early as the preschool years, particularly in competitive situations.     

Type A behavior in normal and hyperactive children: multisource evidence of overlapping constructs

1 goal was to identify correlates of the Type A "coronary-prone" Behavior Pattern (TABP) in children. A second was to examine the overlap between hyperactivity and TABP. In Study 1, a diverse set of measures reliably distinguished boys classified as Type A versus Type B on the basis of the MYTH, a teacher rating scale. The MYTH Competition subscale was related to perceived leadership, athleticism, and--when age and IQ were partialed out--to task attention in the classroom. The Impatience-Aggression subscale showed a different and more extensive configuration of correlates, including staff and peer assessments of problematic behaviors as well as classroom observations of noisemaking, verbalization, and social (particularly negative) contact. Hyperactive boys received higher Type A scores than did their comparison peers, a difference attributable to higher scores on the Impatience-Aggression subscale. Study 2, a partial replication conducted with a different group of hyperactive children, yielded a similar configuration of correlates. Discussion focused on the implications of the overlap between TABP and hyperactivity and, more generally, the heterogeneity of children designated Type A.     

Choice and goal-directed behavior in preschool children

Preschool children (3–4 years old) were trained to perform two actions to gain different outcomes, in the form of video clips from different cartoons, before one of these outcomes was devalued by noncontingent exposure. The effect of outcome devaluation was subsequently assessed in an extinction test by giving children the opportunity to perform both actions in the absence of any outcomes. When the two actions were trained concurrently, performance during the test was modulated by outcome value and children showed a preference for the action trained with the currently valued outcome. By contrast, when each action was trained separately on different trials, test performance was insensitive to outcome devaluation. These effects of the training schedules are interpreted in terms of dual-process theories of action control.     

Construct validity of the adjustment scales for children and adolescents and the preschool and kindergarten behavior scales: Convergent and divergent evidence

Construct validity (convergent and divergent) of the Adjustment Scales for Children and Adolescents (ASCA; McDermott, Marston, & Stott, 1993) and the Preschool and Kindergarten Behavior Scales (PKBS; Merrell, 1994a) is presented. Regular classroom teachers (n = 38) randomly selected 5‐ and 6‐year‐old children (N = 123) and rated them on the ASCA and PKBS in counterbalanced order. Convergent evidence of construct validity was observed for the PKBS Externalizing Problems scale and the ASCA Overactivity syndrome. Divergent evidence of construct validity was provided for the PKBS Externalizing Problems scale and ASCA Underactivity syndrome. Convergent and divergent evidence of construct validity for the PKBS Internalizing Problems scale and ASCA Overactivity and Underactivity syndromes was mixed. Results were identical to those of Canivez and Bordenkircher (2002). © 2002 Wiley Periodicals, Inc. Psychol Schs 39: 621–633, 2002.     

The Study Process Questionnaire: A construct validation study

The Study Process Questionnaire (Biggs, 1987) has been widely used in studies investigating learning behaviours in tertiary education. Many of the studies that have used the instrument have investigated the construct validity of the SPQ using a variety of factor analytic methods and techniques in an atheoretical way. Contrary to this method, Burnett and Dart (1997) argued that the hypothesised structure of a scale should be used when assessing the construct validity of an existing instrument. This study investigated the factor structure of the SPQ using a theoretical approach and found strong support for the three approaches to learning structure of the instrument.     

Storybook models and achievement behavior of preschool children

The effects of orally presented storybook models on children's cognitive achievement behavior were assessed in two experiments. Experiment I involved 100 preschool-age children who were given one exposure to either a story depicting achievement behaviors by a male/female model, or a control story describing no achievement behavior. Subjects then were asked to perform a related achievement task. No significant modeling effects were found, but a significant relationship existed between the children's recall of the story content and their performance on the subsequent task. Experiment 11 employed 60 preschool-age children who were given repeated exposures (3 to 4) to, and group discussion of, the same achievement stories or non-achievement control story. A significant relationship was observed between type of story and type of solutions to the subsequent achievement task. These findings are discussed in the context of modeling theory, with practical implications.     

Type of day-care and preschool intellectual development in disadvantaged children

Levels and patterns of intellectual development of 3 groups of socioeconomically disadvantaged children were compared. The groups consisted of (1) children who were randomly assigned to receive extensive university-based intervention group day-care, (2) children whose parents placed them in community day-care centers for varying amounts of time, or (3) children whose parents chose little to no center-based day-care for their children. Two repeated-measures analyses of variance were performed to identify possible day-care effects on IQ level and on patterns of infant and preschool cognitive development. The results suggest that quality community day-care, as well as intervention day-care, may positively change both the level and pattern of preschool intellectual development of socioeconomically disadvantaged children.     

Developmental trajectories of disruptive behavior problems in preschool children of adolescent mothers

Using hierarchical linear modeling (HLM), we analyzed individual developmental trajectories of disruptive behavior problems between ages 3.5 to 6.0 years for 183 children of adolescent mothers. We examined how the level of problem behavior (intercept) and the rate of change over time (slope) are influenced by child's sex, mother's depression/anxiety symptoms, and mother's use of negative control for regulating child behavior. On average, disruptive behavior decreased from age 3.5 to 6.0. Child sex and maternal depression/anxiety related to the level of behavior problems but not to the rate of change. Boys and children of more depressed/anxious mothers exhibited higher levels of disruptive behavior. Maternal negative control was associated with both level of disruptive behavior and rate of change, and negative control mediated the effects of maternal depression/anxiety. Greater negative control corresponded to higher levels of behavior problems and no reduction in their display over time. Child race moderated effects of negative control.
