The MEDLINE experience at Yale: 1986-1996

The Cushing/Whitney Medical Library began providing end-user access to MEDLINE in 1986 and switched to the OVID system in 1993. MEDLINE is a core service of the library, and the choice of delivery systems has had a significant impact throughout the Yale-New Haven Medical Center. This paper describes the user response to MEDLINE, discusses the effects of MEDLINE on other library services, and suggests ways in which technology, policy, and funding have influenced use. Yale's experience suggests that removing barriers in all three areas can dramatically expand the points of access, the number of users, and the amount of use with manageable effects on other library services.     

Nine years after child sexual abuse

OBJECTIVE: During 1988-1990, 103 children presented to Child Protection Units (CPU) at two children's hospitals in Sydney, Australia. Nine years later, the psychological adjustment of these young people (mean age=19.1 years, SD=3.4 years; range=14-25 years) was compared with that of non-abused young people of similar age and gender to assess group differences and examine potential risk factors. METHOD: At intake, data on the nature of the index sexual abuse, demographics and the family environment were collected by clinicians. A comparison group, of similar age and gender, was selected from schools in the catchment area of the CPUs. Six years after presentation for the abuse, records of the statutory child protection authority were checked to determine any further notifications for abuse and/or neglect. Nine years after intake, 49 of the abused young people and 68 of the non-abused young people and/or their parents were interviewed and assessed. RESULTS: The sexually abused young people performed more poorly than non-abused young people on psychometric tests of depression (p=.001), self-esteem (p<.001), anxiety (p<.001), behavior (Child Behavior Checklist: p=.01; Youth Self Report: p=.01; Young Adult Self Report: p<.001), and despair (p=.001). They were also more likely to have a history of bingeing (p=.002), self-inducing vomiting (p=.02), smoking cigarettes (p=.01), and using amphetamines (p=.002), ecstasy (p=.002) and cocaine (p=.004). Potential risk factors were in two groups, family and child. Family factors: family functioning, parental drug/alcohol problems, mother's sexual abuse history, mother's depression and socio-economic status. Child factors: despair and hopefulness, number of negative life events, ratings of their father's care, previous notifications for child sexual abuse and placements in out-of-home care by the statutory child protection authority. In the presence of other risk factors, child sexual abuse was a significant predictor of self-esteem, behavior and bingeing. CONCLUSIONS: Rather than focusing only on the individual's child sexual abuse, treatment may also need to address the family's functioning and the individual's feelings of despair.     

Genetic and environmental etiologies of reading difficulties: DeFries-Fulker analysis of reading performance data from twin pairs and their nontwin siblings

Reading performance data from 254 pairs of identical (MZ) and 420 pairs of fraternal (DZ) twins, 8.0 to 20.0 years of age, were subjected to multiple regression analyses. An extension of the DeFries-Fulker (DF) analysis (DeFries & Fulker, 1985, 1988) that facilitated inclusion of data from 303 of their nontwin siblings was employed. In addition to providing estimates of heritability, this analysis yields a test of the difference between shared environmental influences for twins versus siblings (Astrom et al., 2011). Results suggest that proband reading deficits are due substantially to genetic factors (.67 ± .07, p < .001), and that shared environmental influences are significantly higher for members of twin pairs than for those of twins and their nontwin siblings (viz., .25 versus .17, p = .02).     

Race, ethnicity, and culture in child development: contemporary research and future directions

The editors of this special issue reflect on the current status and future directions of research on race, ethnicity, and culture in child development. Research in the special issue disentangles race, ethnicity, culture, and immigrant status, and identifies mediators of sociocultural variables on developmental outcomes. The special issue includes important research on normal development in context for ethnic and racial minority children, addresses racial and ethnic identity development, and considers intergroup processes. The methodological innovations as well as challenges of current research are highlighted. It is recommended that future research adhere to principles of cultural validity described in the text.
