Consistency of hand-preference across the early years: long-term relationship to verbal intelligence and reading achievement in girls

The relationship between consistency of hand preference, left hemispheric specialization, and cognitive functioning was examined in an ongoing longitudinal investigation. Children were classified as consistent or inconsistent in their hand preference across 5 assessments from ages 18 to 42 months. Findings demonstrated that (a) this early classification continued to reveal differences in cognitive functioning from 10 to 17 years but only for girls, (b) consistent girls' performances were continually higher relative to the inconsistent girls on measures of verbal intelligence and reading achievement, (c) differences between the female groups were specifically related to left-hemispheric language specialization, and (d) one factor influencing the consistent girls' development may be the amount of reading exposure received during infancy.     

Measurement of Preoperative Anxiety in Young Children: Self-report Versus Observer-rated

The utility of the self-report Children’s Anxiety and Pain Scale Anxiety subscale (CAPS-A) in comparison to the widely used, observer-rated Modified Yale Preoperative Anxiety Scale (mYPAS) in assessing anxiety in children undergoing day surgery procedures was examined. The CAPS-A test-retest reliability, concurrent validity with the Modified Yale Preoperative Anxiety Scale (mYPAS), and sensitivity to expected increases in anxiety at stressful times during the preoperative period were examined. Levels of observer-rated (mYPAS) and self-reported anxiety (CAPS-A) were obtained from 61 children (3 to 6 years) undergoing day surgery procedures. The CAPS-A demonstrated adequate test-retest reliability. Concurrent validity between the CAPS-A and mYPAS scores was poor. The CAPS-A failed to show sensitivity to the expected increases in anxiety at stressful time-points. Thus, an alternative scoring strategy for the CAPS-A was proposed (i.e., child’s refusal to point was scored as high anxiety). Post-hoc analyses demonstrated good concurrent and adequate convergent validity with the alternative scoring strategy.     

The Emotion Regulation Index for Children and Adolescents (ERICA): A Psychometric Investigation

There is increased recognition of the importance of children learning how to regulate emotions in a functional and adaptive manner for healthy psychological development. However, there is a paucity of tools for assessing emotion regulation during the middle childhood and adolescent years. This study reports on the psychometric evaluation of the 16-item self-report Emotion Regulation Index for Children and Adolescents (ERICA) involving a sample of 1,389 (768 girls, 621 boys) Australian children and adolescents aged 9 to 16 years. Convergent validity for the ERICA is reported with measures of self-conscious emotions (shame, guilt), empathy, childhood depressive symptomatology, and the perceived parenting dimensions of Care and Overprotection. Construct validity assessment using Principal Components Analysis and Confirmatory Factor Analysis yielded three factors: (1) Emotional Control, (2) Emotional Self-Awareness, and (3) Situational Responsiveness. The ERICA was also found to have good internal consistency and to be relatively stable over a four week test-retest period and to be sensitive to age and sex differences. It is concluded that the ERICA is a psychometrically sound measure for the assessment of the identified key aspects of emotion regulation in children and adolescents.     

The Impact of Anger Management Treatment and Rational Emotive Behavior Therapy in a Public School Setting on Social Skills,Anger Management,and Depression

Public school students participated in a group to enhance and improve anger management. The study used a pre-post design with a comparison group. Students were assigned to either Anger Management Treatment or Anger Management plus Rational Emotive Behavior Therapy (REBT). Each child served as his or her own control and received an empirically validated intervention. Pretest–posttest data were evaluated using the Social Skills Rating System, the Children’s Depression Inventory and the Children’s Inventory of Anger. Results indicate that the addition of the REBT component to Anger Management reduced anger as well as depression, while improving social skills, suggesting the addition of a specialized cognitive behavioral component increased the effectiveness of the intervention.     

The information content of panoramic images II: view-based navigation in nonrectangular experimental arenas

Two recent studies testing navigation of rats in swimming pools have posed problems for any account of the use of purely geometric properties of space in navigation (M. Graham, M. A. Good, A. McGregor, & J. M. Pearce, 2006; J. M. Pearce, M. A. Good, P. M. Jones, & A. McGregor, 2004). The authors simulated 1 experiment from each study in a virtual reality environment to test whether experimental results could be explained by view-based navigation. The authors recorded a reference image at the target location and then determined global panoramic image differences between this image and images taken at regularly spaced locations throughout the arena. A formal model, in which an agent attempts to minimize image differences between the reference image and current views, generated trajectories that could be compared with the search performance of rats. For both experiments, this model mimics many aspects of rat behavior. View-based navigation provides a sufficient and parsimonious explanation for a range of navigational behaviors of rats under these experimental conditions.     

Modeling the Information Preferences of Parents of Children with Mental Health Problems: A Discrete Choice Conjoint Experiment

Although materials informing parents about children’s mental health (CMH) problems can improve outcomes, we know relatively little about the design factors that might influence their utilization of available resources. We used a discrete choice conjoint experiment to model the information preferences of parents seeking mental health services for 6 to 18 year olds. Parents completed 30 choice tasks presenting experimentally varied combinations of 20 four-level CMH information content, transfer process, and outcome attributes. Latent class analysis revealed three segments with different preferences. Parents in the Action segment (43%) chose materials providing step-by-step solutions to behavioral or emotional problems. They preferred weekly meetings with other parents and coaching calls from a therapist. The Information segment (41%) chose materials helping them understand rather than solve their child’s problems. These parents were more sensitive to logistical factors such as receiving information in groups, the location where information was available, the modality in which the information was presented, and the time required to obtain and use the information. The Overwhelmed segment (16%) reported more oppositional and conduct problems, felt their children’s difficulties exerted a greater adverse impact on family functioning, and reported higher personal depression scores than those in the Action or Information segments. Nonetheless, they did not choose information about, or solutions to, the problems their children presented. Simulations predicted that maximizing utilization and realizing the potential benefits of CMH information would require knowledge transfer strategies consistent with each segment’s preferences.

Severe Life Events and Chronic Adversities as Antecedents to Anxiety in Children: A Matched Control Study

The present study compared the number of severe life events and chronic adversities as reported retrospectively by mothers of children with an anxiety disorder (n = 39) prior to the onset of their most recent episode, with controls (n = 39) matched for age and sex. The parent version of the Psychosocial Assessment of Childhood Experiences (PACE) was used to assess chronic adversities (long-term experiences with negative impact on child) and severe life events (discrete life events with high long-term threat). A significantly greater number of severe life events and chronic adversities were assessed prior to onset for anxious children compared to controls. The finding for severe life events held regardless of whether impact ratings were assigned by mothers or a panel of independent raters, suggesting the findings reflect actual as opposed to perceived differences. Results suggest that both discrete and chronic stressors may constitute risk for future episodes of anxiety in children.
