Within-family estimates have been considered a remedy to selection bias in estimates of long-run consequences of teen motherhood. A major critique, however, is that heterogeneity within the family might still bias the estimates. Using Swedish data on biological sisters, I revisit the question of the consequences of teenage motherhood. My…

This study examined 2 samples of adolescents and mothers using a child-based design (Nonshared Environment in Adolescent Development [NEAD] project, N = 395 families) and a parent-based design (Twin Moms [TM] project, N = 236 twin family pairs) to compare genetic and environmental influences on mothering. For both samples, the same measures of…

Using data from 8 random assignment studies and employing meta-analytic techniques, this article provides systematic evidence that welfare and work policies targeted at low-income parents have small adverse effects on some school outcomes among adolescents ages 12 to 18 years at follow-up. These adverse effects were observed mostly for school…

Using data from the 1996 National Longitudinal Survey of Youth (NLSY79) merged mother-child sample, we investigate the impact of two family events, parental divorce and the birth of a sibling, on the cognitive stimulation and emotional support provided to children in the home. We use fixed-effect regression techniques to control for unmeasured…

This study investigates whether childhood health acts as a mechanism through which socioeconomic status is transferred across generations. The study uses data from the Panel Study of Income Dynamics to track siblings and to estimate fixed-effects models that account for unobserved heterogeneity at the family level. The results demonstrate that…

Despite unmistakable evidence that incest offenders rarely stop with one child, courts routinely fail to protect an incest victim's siblings. Many courts simple deny that a parent's sex act with one child signals risk to others. Nevertheless, even those courts that acknowledge a sibling's risk reach wildly different results when confronting…

Responds to the comment by John J. Sigal about the article by David, Dytrych, and Matejcek which showed the long-term negative psychological effects of unwantedness, up to 35 years after birth. The authors state that they were pleased to note Sigal's observation that the conclusions from their Prague study are consistent with findings reported by…

Background: A minority of patients with attention-deficit hyperactivity disorder (ADHD) do not respond favorably to methylphenidate. This has been partially associated with homozygosity for the Dopamine transporter (DAT1) 10-repeat allele and the presence of one or two Dopamine D4 receptor (DRD4) 7-repeat alleles. This study examined the sibling…

Background: Findings from family and twin-based studies of Attention Deficit/Hyperactivity Disorder (ADHD) have indicated that inattentive and combined subtypes cluster together among sibling pairs who both express ADHD symptoms. The current report examines the familial clustering of ADHD subtypes, defined according to latent class and DSM-IV…

The Prader-Willi/Angelman Critical Region (PWACR; Chromosome 15q11-13) is of interest as a potential locus for genes conferring susceptibility to autism spectrum disorders (ASD). This report describes a female proband referred for evaluation of a possible ASD. Genetic analyses indicated that the proband, her father and one of her sisters, carried…

Traditional legal and social forces have hindered the adoption of children by gay and lesbian individuals and couples. Using a convenience sample drawn from gay and lesbian support groups and Internet sites, this exploratory study examines adoptive families with gay and lesbian parents in terms of family functioning capabilities, child's behavior,…

Objective: It is widely presumed that when children are hit by peers or siblings, it is not as serious as similar acts between adults or older youth, which would be termed, "assaults" and "violent crimes". The goal of this study was to compare the violent peer and sibling episodes of younger children to those of older youth in terms of their…

This examination of exposure of Palestinian adolescents to family violence found alarming rates of witnessing interparental and experiencing parent-to-child aggression and violence. Rates correlated with parents' levels of education, place of residence, family size, religious affiliation, family income, and housing conditions, as well as with…

Recent studies have used increasingly complex methodologies to estimate the effect of peer characteristics--race, poverty, and ability--on student achievement. A paper by Hanushek, Kain, and Rivkin using Texas state testing data has received particularly wide attention because it found a large negative effect of school percent black on black math…

Objective: Many children with conduct disorder develop life-course persistent antisocial behavior; however, other children exhibit childhood-limited or adolescence-limited conduct disorder symptoms and escape poor adult outcomes. Prospective prediction of long-term prognosis in pediatric and adolescent clinical settings is difficult. Improved…
