This study examined whether the benefits of reading tutoring in first grade were moderated by children's level of attention problems. Participants were 581 children from the intervention and control samples of Fast Track, a longitudinal multisite investigation of the development and prevention of conduct problems. Standardized reading achievement measures were administered after kindergarten and 1st grade, and teacher ratings of attention problems were obtained during 1st grade. During 1st grade, intervention participants received three 30-min tutoring sessions per week to promote the development of initial reading skills. Results replicated prior findings that attention problems predict reduced 1st grade reading achievement, even after controlling for IQ and earlier reading ability. Intervention was associated with modest reading achievement benefits for inattentive children without early reading difficulties, and substantial benefits for children with early reading difficulties who were not inattentive. It had no discernible impact, however, for children who were both inattentive and poor early readers. Results underscore the need to develop effective academic interventions for inattentive children, particularly for those with co-occurring reading difficulties.  相似文献

Parent–Child Interaction Therapy and Chronic Illness: A Case Study   总被引:1,自引:0,他引:1  
We examined the outcome of parent–child interaction therapy (PCIT) for a child diagnosed with Oppositional Defiant Disorder (ODD) and cancer. Robert, a 4-year-old Caucasian male, showed significant and meaningful changes in his behavior over the course of 13 weeks of PCIT, and Robert no longer met diagnostic criteria for ODD following treatment. His scores on the Eyberg Child Behavior Inventory and the Achenbach Child Behavior Checklist were in the clinical range before treatment and in the normal range at the conclusion of treatment. His mother also reported dramatic improvements in Robert's behavior during medical visits. Physician and social worker reports were consistent with her report. Such anecdotal data may have implications for the generalization of compliance to the medical setting for children with chronic illnesses. The results of this case study should prompt further investigation of parent-training interventions for children with chronic illnesses and disruptive behavior.  相似文献

The paper presents major ethical, legal and methodological problems related to the use of placebo in mental disorders, especially in depression. It is pointed out that although authoritative groups of experts and numerous publications in the field of psychopharmacology indicate advisability of the double blind design with placebo in clinical trials of antidepressants, in recent years there have been more and more voices questioning legitimacy of this method. Objections of an ethical nature are raised, and reliability of this approach is put into doubt from the methodological viewpoint. These issues are discussed in more detail in the paper. Available alternative solutions should be implemented in psychotropic drug studies. The author shares these objections and doubts of an ethical nature, and believes that the placebo procedure is not a necessity in clinical trials of antidepressants. An earlier version of this paper was presented at an international conference, “Placebo: Its Action and Place in Health Research Today,” held in Warsaw, Poland on 12–13 April, 2003.  相似文献

Can children reason the Bayesian way? We argue that the answer to this question depends on how numbers are represented, because a representation can do part of the computation. We test, for the first time, whether Bayesian reasoning can be elicited in children by means of natural frequencies. We show that when information was presented to fourth, fifth, and sixth graders in terms of probabilities, their ability to estimate the Bayesian posterior probability was zero. Yet when the same information was presented in natural frequencies, Bayesian reasoning showed a steady increase from fourth to sixth grade, reaching an average level of 19, 39, and 53%, respectively, in two studies. Sixth graders' performance with natural frequencies matched the performance of adults with probabilities. But this general increase was accompanied by striking individual differences. More than half of the sixth graders solved most or all problems, whereas one third could not solve a single one. An analysis of the children's responses provides evidence for the use of three non-Bayesian strategies. These follow an overlapping wave model of development and continue to be observed in the minds of adults. More so than adults' probabilistic reasoning, children's reasoning depends on a proper representation of information.  相似文献

This study investigates the long-term effects of parental divorce on adolescent psychological adjustment and well-being, and to what extent the effects are accounted for by parental psychological distress. Data were collected among 8,984 Norwegian adolescents (13-19 years) and their parents. Outcome variables were symptoms of anxiety and depression, subjective well-being, and three areas of school problems. Parental divorce was found to be associated with both higher mean levels and larger variances in adolescent problems. Divorce and parental distress contributed independently to adolescent distress, supporting the notion of "double exposure" effects. The prevalence of adolescents with substantial distress symptoms was 14% among those with non-distressed non-divorced parents and 30% among those with divorced and distressed parents. In general effects remained when controlling for demographic factors. Long-term effects of divorce on symptoms of anxiety and depression were stronger among girls than among boys.  相似文献

This study examined whether characteristics of behavioral items reported by parent and child are related to parent–child agreement. Data were collected from 20 judges rating 59 child behaviors on 11 dimensions hypothesized to affect parent–child agreement. Data from 675 parent–child dyads (85% female caregivers, 62% male children, aged 7–17) reporting on 59 child behaviors were used to examine agreement. Behavior characteristics accounted for 43% of variability in parent–child agreement. Three components, saliency to the parent, saliency to the child, and observability/willingness to report, contributed uniquely to prediction of agreement.  相似文献

The role of callous-unemotional (CU) traits and conduct problems in predicting conduct problem severity, severity and type of aggression, and self-reported delinquency at a 1-year follow-up was investigated in a sample of 98 children (mean age 12.43; SD = 1.72) recruited from a community-wide screening. Children with both CU traits and conduct problems had a greater number and variety of conduct problems at follow-up than children who at the screening had high levels of conduct problems alone. However, this poorer outcome for children with CU traits could largely be accounted for by differences in initial level of conduct problem severity. Children with CU traits and conduct problems were also at risk for showing higher levels of aggression, especially proactive aggression, and self-reported delinquency. Importantly, these outcomes could not be solely explained by initial level of conduct problem severity. Finally, CU traits predicted self-reported delinquency in some children who did not initially show high levels of conduct problems and this predictive relationship seemed to be strongest for girls in the sample who were high on CU traits but who did not show significant conduct problems.  相似文献

When children in foster care are reunified with their families of origin they encounter changes that may influence their well-being in both positive and negative ways. We examined the effects of reunification among 218 children in foster care to test an integrative model of the effects of reunification using structural equation modeling. We hypothesized that reunification would exert indirect effects on subsequent child adjustment via changes in adverse life events, perceived social isolation, and mental health service utilization. Results indicated no direct effect of reunification on subsequent internalizing problems, but reunification was related to increased adverse life events that, in turn, were related to elevated symptoms. Second, reunification was negatively associated with mental health service use. Finally, reunification was associated with decreased child perceptions of social isolation. In summary, reunification with biological parents is associated with multiple environmental changes, with most but not all effects indicating negative consequences.  相似文献

Associations among neighborhood structure, parenting processes, and the development of externalizing behavior problems were investigated in a longitudinal sample of early adolescents (from age 11 to 13). Mothers' reports of parental monitoring (at age 11), mothers' and youths' reports of the amount of youths' unsupervised time (at age 11), and youths' reports of positive parental involvement (at age 12) were used to predict initial levels (at age 11) and growth rates in youths' externalizing behavior as reported by teachers. Census-based measures of neighborhood structural disadvantage, residential instability, and concentrated affluence were expected to moderate the effects of parenting processes (e.g., parental monitoring) on externalizing behavior. Hierarchical linear modeling results revealed that less parental monitoring was associated with more externalizing behavior problems at age 11, and more unsupervised time spent out in the community (vs. unsupervised time in any context) and less positive parental involvement were associated with increases in externalizing behavior across time. Furthermore, the decrease in externalizing levels associated with more parental monitoring was significantly more pronounced when youths lived in neighborhoods with more residential instability.  相似文献

In this paper the refinement and psychometric properties of the Infant–Toddler Social and Emotional Assessment (ITSEA) are described. Results from a sociodemographically diverse birth cohort sample of 1,235 parents of children between the ages of 12 and 36 months are presented. Confirmatory factor analyses supported the hypothesized Internalizing, Externalizing, Regulatory, and Competence domains as well as the 17 individual scales that comprise the ITSEA. Findings for 3 additional indices useful in identifying significant psychopathology are presented. Subgroup analyses revealed structural invariance and expected mean level differences across both child sex and 6-month age bands. Child sex differences emerged for some problem and most competence scales, with boys rated as higher on Activity–Impulsivity and girls rated higher on Anxiety and most Competence scales. All competence scores increased across age groups. Problem behaviors showed a more mixed developmental pattern. Test–retest and interrater reliability were acceptable. Associations between the ITSEA and independent evaluator ratings and parental ratings of child behavior problems, temperament, and parental distress support the validity of the instrument.  相似文献
