ABSTRACT Data from the National Institute of Child Health and Human Development Study of Early Child Care were examined to test whether: attention deficit/hyperactivity disorder (ADHD) symptoms remain stable from 54 months through early elementary school; behavioral inhibition and attention deficits assessed at 54 months predict ADHD symptoms in elementary school, even after controlling for their temporal stability; and early behavioral inhibition and attention deficits moderate the longitudinal stability in ADHD symptoms. Data were examined using continuous and categorical measures of symptoms. Modest stability in ADHD symptoms from 54 months to third grade was found. Measures of inhibition and inattention predicted later teacher ratings uniquely, but no evidence was found for moderation. Measures of preschool behavioral inhibition also predicted "persistently at risk status" defined by elevated teacher ratings over time. Results are discussed in terms of executive and motivational facets of inhibition that may be related to early signs of ADHD.

    ABSTRACT: Background Evidence-based psychosocial interventions such as parent training programs are strongly recommended as first-line treatment for preschool-age children with or at-risk of attention deficit/hyperactivity disorder (AD/HD). Objective Evaluate the effectiveness of the Incredible Years Basic Parent Training (IY) in hyperactive and inattentive behaviors of Portuguese preschoolers. Methods One hundred children, between three and six years-old, with AD/HD behaviors, who were part of a larger randomized controlled trial in which participants were allocated to either an intervention or control group. In this subsample analysis, there were 52 participants in the intervention condition (IYC) and 48 in the waiting-list control condition (WLC). Multi-informants and multi-measures of child and parenting behaviors were taken before and after the 14-week intervention. Results Medium-to-large intervention effects were found in primary caregivers’ reported measures of children’s AD/HD behaviors and on self-reported parenting practices. Independent observations indicated significant short-term effects on positive parenting and coaching. Primary caregivers had a high attendance rate and reported high satisfaction with the program. Additionally, 43 % of children in the IYC clinically improved in the primary AD/HD outcome measure, compared with 11 % in the WLC. Conclusions Preliminary results suggest that IY parent training seems to be an effective tool, making the difference in the behavior of Portuguese preschoolers with early signs of AD/HD and their mothers.

    ABSTRACT: OBJECTIVE This longitudinal study examined if changes in neuropsychological functioning were associated with the trajectory of symptoms related to attention deficit hyperactivity disorder (ADHD) and impairment between preschool and school age. METHOD The sample consisted of 3- and 4-year-old children (N=138) who were identified as being at risk for ADHD based on parent and teacher reports. Neuropsychological functioning was measured annually using the NEPSY at four time points (mean ages, 4.19, 5.36, 6.35, and 7.35 years). ADHD symptoms and impairment were assessed with semiannual parent and teacher reports using the ADHD Rating Scale-IV and the Children's Problems Checklist at 10 time points (mean ages at baseline and final assessment, 4.19 and 8.81 years, respectively). Hierarchical linear modeling was used to assess the trajectories of change in neuropsychological functioning and ADHD severity as well as the association of change in neuropsychological functioning with change in ADHD severity over time. RESULTS Baseline neuropsychological functioning was not significantly associated with the slope of change in ADHD severity. However, the magnitude of change in neuropsychological functioning was linearly associated with the trajectory of ADHD symptom severity and impairment, such that individuals with greater neuropsychological growth over time had a greater diminution of ADHD severity and impairment. Family socioeconomic status at baseline was significantly associated with initial ADHD severity and impairment, but not with change over time. CONCLUSIONS Interventions that enhance neuropsychological functioning at an early age may be beneficial in attenuating long-term ADHD severity and impairment.

    ABSTRACT: The day-night paradigm, where children respond to a pair of pictures with opposite labels over a series of trials, is a widely used measure of interference control. Recent research found that a happy-sad variant of the day-night task was significantly more difficult than the standard day-night task. The present research examined whether the perceptual discriminability of the happy-sad task pictures impacts young children's interference control. When test card pairs were equally distinct between conditions, children performed similarly regardless of whether the happy-sad or day-night response terms were employed (Experiment 1). Two versions of the happy-sad task were administered in Experiment 2 and children experienced significantly more interference when the stimuli were perceptually similar than when they were distinct. Theoretical implications for the role attentional demands play in interference control in Stroop-like tasks for pre-readers are discussed.
