Parents' and children's reports of behavioural-emotional problems in 116 children assessed by the Child Assessment Schedule developed by Hodges et al. (Journal of the American Academy of Child Psychiatry, 21, 468-473, 1982) and the Graham & Rutter Parent Interview (British Journal of Psychiatry, 114, 581-592, 1968), both semi-structured interviews, revealed(More)
This study concerns the second, more clinically oriented, part of our epidemiological project. The prevalence of child psychiatric disorders in random samples of 8- and 11-year-old children is assessed by using standardized parent- and child-interviews. The relationships between different measures of child psychopathology are determined. Furthermore,(More)
The relationship between major life events and changes, across a 2-yr period, in the level of parent-reported behavioural/emotional problems in 1397 children from a general population sample was investigated using a highly modified version of the Coddington Life Events Record and the Achenbach Child Behavior Checklist. The life event questionnaire used in(More)
In this 4-year follow-up of behavioral/emotional problems in an epidemiological sample of 1,200 children originally aged 4 to 12 years assessed with the Achenbach Child Behavior Checklist (CBCL), high stability in the level of CBCL total problem scores was found. Stability of problem behavior was equally substantial for ages 4 to 12 and both sexes.(More)
OBJECTIVE the purpose of this study was to determine the 6-year longitudinal course of psychiatric disorders in children from the general population commencing at age 4 to 11 years. METHOD three groups of children were selected on the basis of Child Behavior Checklist ratings obtained at 2-year intervals: "persisters," "decreasers," and "increasers."(More)
Ionization is the dominant response of atoms and molecules to intense laser fields and is at the basis of several important techniques, such as the generation of attosecond pulses that allow the measurement of electron motion in real time. We present experiments in which metastable xenon atoms were ionized with intense 7-micrometer laser pulses from a(More)
This study is a clinical extension of two previous epidemiological studies on problem behavior in international adoptees. In depth pictures were obtained by clinical interviews of 132 14-year-old international adoptees and their parents. Children were selected on the basis of previously obtained Child Behavior Checklist (CBCL) scores. Clinical severity(More)
This study was aimed to identify the risk factors of aggressive behaviour in adolescents (1318 years), and to describe available intervention strategies. The findings are evaluated on the basis of their implications for nursing practice. Aggressive behaviour in adolescent psychiatric settings is a neglected research area. The consequences of aggressive(More)
We have used two-color time-resolved spectroscopy to measure the relaxation of electron spin polarizations in a bulk semiconductor. The circularly polarized pump beam induces a polarization either by direct excitation from the valence band, or by free-carrier (Drude) absorption when tuned to an energy below the band gap. We find that the spin relaxation(More)
