Predicting developmental outcomes at school entry using a multiple-risk model: four American communities. The Conduct Problems Prevention Research Group.
(1/698)
The contributions of different risk factors in predicting children's psychological and academic outcomes at the end of 1st grade were examined. Using a regression model, levels of ecobehavioral risk were assessed in the following order: specific demographics, broad demographics, family psychosocial status, mother's depressive symptoms, and neighborhood quality. Participants were 337 families from 4 American communities. Predictor variables were assessed in kindergarten, and teacher, parent, and child outcomes (behavioral and academic) were assessed at the end of 1st grade. Results indicated that (a) each level of analysis contributed to prediction of most outcomes, (b) 18%-29% of the variance was predicted in outcomes, (c) a common set of predictors predicted numerous outcomes, (d) ethnicity showed little unique prediction, and (e) the quality of the neighborhood showed small but unique prediction to externalizing problems.

Further analysis of the separate and interactive effects of methylphenidate and common classroom contingencies.
(2/698)
We evaluated separate and interactive effects between common classroom contingencies and methylphenidate (MPH) on disruptive and off-task behaviors for 4 children with a diagnosis of attention deficit hyperactivity disorder. Analogue conditions consisting of contingent teacher reprimands, brief time-out, no interaction, and alone were conducted in a multielement design. Medication status (MPH or placebo) was alternated across days in a superordinate multielement design. Results indicate that (a) the behavioral effects of MPH were influenced by one or more of the analogue conditions for each participant, and (b) time-out was associated with zero or near-zero levels of both disruptive and off-task behavior for 3 of the 4 participants during MPH and placebo conditions. Implications for the clinical effectiveness of MPH and possible behavioral mechanisms of action of MPH in applied settings are discussed. (+info)
Biochemical hypothyroidism secondary to iodine deficiency is associated with poor school achievement and cognition in Bangladeshi children.
(3/698)
Iodine deficiency in pregnancy leads to poor cognitive function in the offspring; however, the effect of concurrent iodine deficiency on school-aged children is not clear. Several studies have shown that school children in iodine-deficient villages have poorer cognitive function than children in iodine-sufficient villages. However, villages differ in many factors that may also detrimentally affect children's development. In addition, the children's nutritional and health status has not usually been taken into account. In this study, we compared the cognitive function and school achievement levels of 170 children who had recently had low thyroxine (T4) levels [T4 /=70 nmol/L (euthyroid)]. The children were matched for school and grade level and came from the same iodine-deficient regions in rural Bangladesh. They were given a battery of cognitive, motor and school achievement tests. We also measured their nutritional status, examined their stools for geohelminths and assessed their home environments. A factor analysis of cognitive and motor function tests yielded two factors, a general cognitive factor and a fine motor factor. The children's height and arm circumference, experience of hunger, parental characteristics and stimulation in the home made independent contributions to their test scores. Controlling for these variables, the hypothyroid children performed worse than the euthyroid children on reading and spelling and the general cognitive factor. These findings indicate that a large number of disadvantages including hypothyroidism are related to the poor development of these children. (+info)
A comparison of language achievement in children with cochlear implants and children using hearing aids.
(4/698)
English language achievement of 29 prelingually deaf children with 3 or more years of cochlear implant (CI) experience was compared to the achievement levels of prelingually deaf children who did not have such CI experience. Language achievement was measured by the Rhode Island Test of Language Structure (RITLS), a measure of signed and spoken sentence comprehension, and the Index of Productive Syntax (IPSyn), a measure of expressive (signed and spoken) English grammar. When the CI users were compared with their deaf age mates who contributed to the norms of the RITLS, it was found that CI users achieved significantly better scores. Likewise, we found that CI users performed better than 29 deaf children who used hearing aids (HAs) with respect to English grammar achievement as indexed by the IPSyn. Additionally, we found that chronological age highly correlated with IPSyn levels only among the non-CI users, whereas length of CI experience was significantly correlated with IPSyn scores for CI users. Finally, clear differences between those with and without CI experience were found by 2 years of post-implant experience. These data provide evidence that children who receive CIs benefit in the form of improved English language comprehension and production. (+info)
Adversity and psychosocial competence of South African children.
(5/698)
Black children in South Africa commonly experience low socioeconomic status and community violence. Parents (N = 625) in a longitudinal study of urbanization responded to structured questionnaires related to resilience, affability, maturity, and school readiness of their six-year olds. SES was found to have an inverse and linear relation to competence at age six; the relationship to violence was curvilinear, with children from moderately safe communities achieving better outcomes than those from very safe or very unsafe ones.

Contextual factors in substance use: a study of suburban and inner-city adolescents.
(6/698)
Objectives in this research were to examine contextual differences in correlates of substance use among high school students. The focus was on two broad categories of adjustment indices: personal psychopathology (internalizing and externalizing problems) and behaviors reflecting social competence (academic achievement, teacher-rated classroom behaviors, and peer acceptance or rejection). Associations between drug use and each of these constructs were examined in two sociodemographically disparate groups: teens from affluent, suburban families (n = 264), and low socioeconomic status adolescents from inner-city settings (n = 224). Results indicated that suburban youth reported significantly higher levels of substance use than inner-city youth. In addition, their substance use was more strongly linked with subjectively perceived maladjustment indices. Comparable negative associations involving grades and teacher-rated behaviors were found in both groups, and among suburban males only, substance use showed robust positive associations with acceptance by peers. Results are discussed in terms of developmental perspectives on adolescent deviance, contextual socializing forces, and implications for preventive interventions and treatment. (+info)
Truancy and perceived school performance: an alcohol and drug study of UK teenagers.
(7/698)
This study is based on a subsample of 15- and 16-year-old school students from the UK, part of the European School Project on Alcohol and Other Drugs (ESPAD). Information was available on truancy rates, perceived school performance, family structure, lifestyle, and usage of alcohol, cigarettes and illicit drugs in 6409 teenagers. Living in a single-parent family, lack of constructive hobbies, presence of psychiatric symptoms, and an aggressive outgoing delinquent lifestyle bore the strongest associations to truancy and to perceived school performance. There were also strong relationships between both these last two variables and use of alcohol, cigarettes, and illicit drugs. However, the effects of alcohol, cigarettes, and illicit drugs were largely accounted for by other variables. Having at least one parent who both supported the respondent and who exercised some control was predictive of better perceived school performance. (+info)
Intellectual, neuropsychological, and academic functioning in long-term survivors of leukemia.
(8/698)
OBJECTIVE: To assess the effects of treatment for acute lymphoblastic leukemia (ALL) on children's cognitive functioning. METHOD: Participants were long-term survivors of ALL treated with cranial irradiation and central nervous system (CNS) chemotherapy (n = 20), or CNS chemotherapy only (n = 21), healthy children (n = 21), and children with chronic asthma (n = 21). The groups were compared on measures of intellectual, neuropsychological, and academic functioning. RESULTS: CNS chemotherapy, with and without cranial irradiation, was associated with significantly lower levels of intellectual and academic functioning. Children with chronic asthma obtained lower scores than healthy controls, but these differences were not significant. Tests of neuropsychological functioning did not consistently separate the groups. CONCLUSIONS: CNS chemotherapy and, to a lesser extent, chronic illness both contribute to the poorer performance of long-term survivors of ALL on measures of intellectual and academic functioning.
