Risk factors for psychopathology in children with intellectual disability: A prospective longitudinal population-based study
Background: This study examined risk factors for the development of psychopathology in children with intellectual disability (ID) in the developmental, biological, family and social-ecological domains. Methods: A population sample of 968 children, aged 6-18, enrolled in special schools in the Netherlands for educable and trainable ID were assessed at Time 1. A random 58% were re-contacted about 1 year later, resulting in a sample of 474 at Time 2. Results: Psychopathology was highly consistent over 1 year. Risk factors jointly accounted for significant, but small, portions of the variance in development of psychopathology. Child physical symptoms, family dysfunction and previous parental mental health treatment reported at Time 1 were uniquely associated with new psychopathology at Time 2. Conclusions: Prevention and early intervention research to find ways to reduce the incidence of psychopathology, possibly targeting family functioning, appear important. © 2006 Blackwell Publishing Ltd
Psychopathology in Children with Intellectual Disability: Assessment, prevalence and predictive factors
__Abstract__
This study’s main focus is psychopathology in children and adolescents with intellectual
disability (ID). The main topics addressed in this study are the assessment of psychopathology
in children (also including adolescents) with ID, the prevalence and impact of
psychopathology in children with ID, and associated risk factors.
The present study is an epidemiological study. In short, epidemiological studies are
concerned with the study of patterns of disease occurrence in human populations, and with the
factors that influence those patterns. Epidemiological research is empirical by nature, involves
quantification of relevant factors, is probabilistic, and uses the method of comparison as a
basic tool (Verhulst, 1995).
The number of studies addressing the epidemiology of psychopathology in children with
ID is limited, though it has increased in the last decade. Few systematic studies on the
relationship between ID and psychopathology in children exist. Theoretical considerations
and empirical findings suggest that children with ID are at higher risk than children without
ID for developing psychopathology. Further, several other issues hamper our understanding
of the subject, such as the use of different definitions for both ID and psychopathology, the
lack of standardized assessment procedures, and the use of not so representative samples.
In this chapter we will discuss some of the major issues in this research-field. Further, we
will account for the choices made in this study in an effort to provide good quality data on the
epidemiology of psychopathology in children with ID
Quantization of the Damped Harmonic Oscillator Revisited
We return to the description of the damped harmonic oscillator by means of a
closed quantum theory with a general assessment of previous works, in
particular the Bateman-Caldirola-Kanai model and a new model recently proposed
by one of the authors. We show the local equivalence between the two models and
argue that latter has better high energy behavior and is naturally connected to
existing open-quantum-systems approaches.Comment: 16 page
Attentional control and executive functioning in school-aged children: Linking self-regulation and parenting strategies
Good parenting strategies can shape children’s neurocognitive development, yet little is known about the nature of this relation in school-aged children and whether this association shifts with age. We aimed to investigate the relation between parenting strategies observed during a home visit and children’s performance-based attentional control and executive functioning (N = 98, aged 4–8 years). Linear and curvilinear regression analyses showed that children of parents who were more supportive, were less intrusive, and asked more open-ended questions displayed better inhibitory control. In addition, children of parents who asked relatively more open-ended than closed-ended questions showed better performance on inhibition, working memory, and cognitive flexibility tasks. Curvilinear relations indicated the presence of an optimal amount of closed-ended and elaborative questions by parents—that is, not too few and not too many—which is linked to increased performance on attentional and inhibitory control in children. Higher parental intrusiveness and more frequent elaborative questioning were associated with decreased inhibitory control in younger children, whereas no such negative associations were present in older children. These results suggest that susceptibility to certain parenting strategies may shift with age. Our findings underscore the importance of adaptive parenting strategies to both the age and needs of school-aged children, which may positively affect their self-regulation skills.Development Psychopathology in context: clinical setting

Reflective Goal-Setting Improves Academic Performance in Teacher and Business Education: A Large-Scale Field Experiment
Students often have trouble adjusting to higher education and this affects their
performance, retention, and well-being. Scholars have suggested applying reflective goal-
setting interventions, and most have found positive effects on academic performance and
retention. However, one study found no effect at all, stressing the need for understanding
the underlying mechanisms, as they could explain when the intervention works and why.
Thus, we assessed these mechanisms through a rigorous effect test, using an experimental
design and repeated measures. We measured engagement, self-regulated learning,
resilience, grit, wellbeing, academic performance, and retention at three points in a large
scale randomized controlled trial involving first-year teacher and business education
students (N = 1,134). The treatment group earned significantly more course credits and
had lower drop out rates. Contrary to previous findings, these effects were independent of
gender or ethnicity. Grit, self-regulated learning, resilience, or engagement did not
mediate the effects. This study confirmed reflective goal-setting’s small and direct effect
on academic performance, but no mediating or moderating effects. Differences in
implementation fidelity could explain previous studies’ varying effect-sizes
