Abstract

Seven first-grade children with conduct disorders and/or hyperactivity attended full-day sessions at a laboratory school classroom. During an 8-week period, the classroom lighting conditions alternated at the end of each week. During odd-numbered weeks, the classroom was illuminated by a standard cool-white fluorescent system. On even-numbered weeks, illumination was a daylight-simulating fluorescent system of equal footcandles with controls for purported soft X rays and radio frequency (RF). There were no effects of lighting conditions on hyperactive behavior as assessed by (a) independent observations of task orientation or (b) ratings of activity level. A Critical Flicker Fusion (CFF) measure, a reported indicator of visual-sensory fatigue, indicated that the daylight-simulating condition was associated with a decreasing CFF across weeks.

Early childhood externalising behaviour problems: child, parenting, and family-related predictors over time.

This study examined the dynamic relationships between child, parenting, and family-related predictor variables and early childhood externalising behaviour problems. A community sample of 395 Australian children was followed longitudinally, and assessed at 4 and 6 years with the Child Behavior Checklist, Teacher Report Form, and standard measures of parenting, temperament, and familial adversity. Variables based on the average scores across the two assessments and the change in scores between assessments were utilised as predictors of parent-reported and teacher-reported externalising behaviour problems at age 6. It was hypothesised that both higher average scores and more detrimental changes in scores, would independently predict externalising problems at age 6. Multivariable analyses found that the presence of parent-reported child externalising problems in six-year-olds were predicted by: (i) the presence of parent-reported child externalising problems at age 4, (ii) higher average "teacher-reported child externalising behaviour," "inflexible temperament," "non-persistent temperament," and "over-reactive parenting," and (iii) an increased "inflexible temperament" score between age 4 and age 6. The presence of teacher-reported child externalising problems at age 6 was predicted by higher average "parent-reported child externalising behaviour," and "over-reactive parenting." The results provide further evidence of the adverse impact of continuing high levels of temperament difficulties and over-reactive parenting on externalising behaviour in early childhood. However, contrary to expectations, the contribution of including the dynamic change scores was limited.

Cardiac vagal regulation differentiates among children at risk for behavior problems.

A sample of 335 five-year-old children participating in an ongoing longitudinal study was the focus of a study on the effects of emotional and behavioral challenge on cardiac activity in children with different patterns of early childhood behavior problems. The children were placed in one of three behavior problem groups (low behavior problems, risk for externalizing problems, risk for mixed externalizing/internalizing problems) based on their scores on the Child Behavior Checklist for 4-18-year-olds [Achenbach, T.M., 1991. Integrative guide for the 1991 CBCL/4-18, YSR & TRF profiles. University of Vermont Department of Psychiatry, Burlington, VT], completed by their mothers. To assess cardiac vagal regulation, resting measures of respiratory sinus arrhythmia (RSA) and RSA change (vagal withdrawal) to five emotionally and behaviorally challenging tasks were derived. In addition, heart period (HP) and heart period change (HR acceleration) was examined. Results indicated that the behavior problem groups did not differ in terms of resting measures of either RSA or HP. Analyses of the challenge tasks indicated that the children at risk for mixed problems displayed greater cardiac vagal withdrawal across the five tasks than did the other two groups of children. There was a trend for the children at risk for externalizing problems to display less vagal withdrawal than the control group. In addition, the children at risk for mixed problems displayed greater heart rate acceleration to the tasks than did the other two groups of children. Follow-up analyses indicated that the greater cardiac acceleration observed in the mixed group was largely a function of greater vagal withdrawal. These findings are discussed in terms of the emotion regulatory function of cardiac vagal regulation, and its implications for patterns of risk for behavior problems in young children.

Theoretical, developmental & cultural orientations of school-based prevention programs for preschoolers.

Schools are the primary environment in which to conduct prevention programs for school-age children. Educators, policy makers, and psychologist argue that prevention efforts should begin as early as possible to maximize their effectiveness. Surprisingly, there are relatively few school-based prevention programs targeted for preschoolers. Given the evidence supporting earlier rather than later prevention efforts and the fact that many children in the United States attend preschool programs, more research on the feasibility and effectiveness of prevention programs administered in preschool environments is warranted. In this article, we review the existing literature on school-based prevention programs targeted for preschool children. We examine whether school-based prevention programs are theory driven, developmentally appropriate, culturally sensitive, and aimed specifically at symptom reduction or behavior promotion. Based on the findings of this review, our aim is to identify gaps in the prevention research literature regarding programs for preschoolers and propose research to address such gaps to create more effective school-based prevention programs for young children.
