Are there long-term effects of early child care?

Effects of early child care on children's functioning from 4(1/2) years through the end of 6th grade (M age=12.0 years) were examined in the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development (n=1,364). The results indicated that although parenting was a stronger and more consistent predictor of children's development than early child-care experience, higher quality care predicted higher vocabulary scores and more exposure to center care predicted more teacher-reported externalizing problems. Discussion focuses on mechanisms responsible for these effects, the potential collective consequences of small child-care effects, and the importance of the ongoing follow-up at age 15.     

The relation of attachment security to adolescents' paternal and peer relationships, depression, and externalizing behavior

The relation of attachment security to multiple domains of psychosocial functioning was examined in a community sample of 167 early adolescents. Security of attachment organization, assessed using the Adult Attachment Interview, was linked to success in establishing autonomy while maintaining a sense of relatedness both with fathers and with peers, even after accounting for predictions from qualities of the mother-teen relationship. Growth curve analyses revealed links of insecurity to increasing patterns of externalizing behavior and higher and stable patterns of depressive symptoms across adolescence. Implications for a developing theory of the connections of the attachment system to multiple domains of functioning in adolescence are discussed.     

Prevalence of overweight among deaf children

The study examined the prevalence of overweight cases in a sample of 151 deaf children aged 6-11 years. Participants were deaf students attending six elementary schools, both regular and special, in four states. Body mass index (BMI) was calculated using height and weight, plotted on the Center for Disease Control and Prevention (CDC) U.S. BMI-for-age growth charts, then compared to national values for same age and gender (CDC, 2006a, 2006b; National Center for Health Statistics, 2005). The results indicated that the prevalence of overweight deaf children aged 6-11 years was above the national percentage for same age and gender. A larger percentage of boys was overweight (24.7%) than girls (20.4%). After age 8 years, girls showed a consistent decrease in BMI with increasing age, a trend not demonstrated by boys. As a group, deaf children demonstrate a higher prevalence of overweight than national averages.     

Prenatal Antecedents of Newborn Neurological Maturation

Fetal neurobehavioral development was modeled longitudinally using data collected at weekly intervals from 24 to 38 weeks gestation in a sample of 112 healthy pregnancies. Predictive associations between 3 measures of fetal neurobehavioral functioning and their developmental trajectories to neurological maturation in the first weeks after birth were examined. Prenatal measures included fetal heart rate (FHR) variability, fetal movement, and coupling between fetal motor activity and heart rate patterning; neonatal outcomes include a standard neurologic examination ( n  =   97) and brainstem auditory evoked potential (BAEP; n  =   47). Optimality in newborn motor activity and reflexes was predicted by fetal motor activity, FHR variability, and somatic–cardiac coupling predicted BAEP parameters. Maternal pregnancy-specific psychological stress was associated with accelerated neurologic maturation.     

Effectiveness of training health professionals in literature search skills using electronic health databases--a critical appraisal

The objective was to assess the effect on health professionals' skills of one to eight hours literature search and retrieval training from electronic health databases. We searched: Cochrane library (2002; Issue 3), MEDLINE (1977-2002/5), EMBASE (1980-2002/7); CINAHL (1982-2002/5); ASSIA (1982-2002/7), BNI (1994-2002/5), ERIC (1985-2002/6); LISA (1969--current), NRR (2002, Issue 2), the world-wide-web and references. The selection criteria consisted of randomised controlled trials, controlled before and after, and controlled cohort studies in comparison with no training. The intervention had to be one to eight hours training in literature search and retrieval skills for health professionals. The outcome was the effect on health professionals' literature search and retrieval skill levels measured through reliable instruments. For data collection and ana-lysis, one reviewer extracted data and assessed the quality of the studies and the second reviewer checked it. The results indicate that there is some evidence of positive impact on health professionals' skill levels in literature searching and they find the training useful. In conclusion, the size of the positive effect is debatable as only three small and methodologically weak studies met the inclusion criteria and out of those only two showed the positive effect.     

What is Program Evaluation? Generating Knowledge for Improvement

In this introductory article, we discuss the nature of Program Evaluation, describing the concepts that underlie our formal and informal evaluative efforts. Program Evaluation, like any deliberate inquiry process, is about learning. The process explicates program purposes, activities, and outcomes and generates knowledge about their merit and worth. This knowledge can inform planning and lead to program improvement. We present and discuss various definitions of Program Evaluation, focussing on its purposes and uses. We also provide an overview of the inquiry process, grounding the search for merit and worth in the American Evaluation Association's Guiding Principles for Evaluators. Because program evaluations are typically conducted to inform decision makers, we discuss aspects of professional practise that contribute to the use of an evaluation.
