Divorce Disclosures and Adolescents' Physical and Mental Health and Parental Relationship Quality

Two studies were constructed to examine the associations between custodial parents' negative disclosures about the other parent after a divorce and parent–adolescent relational quality (closeness and satisfaction) and adolescents' physical and mental health. In general, the results suggested that even though negative disclosures about the other parent might be associated with more cohesive relationships between custodial parents and adolescents, it does not mean that adolescents are immune to the physical and psychological effects of such disclosures. In Study 2, negative disclosures about the other parent were associated with adolescents' increased reports of physical and mental health symptoms. The results revealed a similar effect for general divorce information and adolescents' mental health. However, there was no association for catharsis and adolescents' physical and mental health. The results from both studies also revealed that adolescents perceived that their custodial parents disclosed more negative information about the other parent than the parents perceived that they disclosed.     

Anti-Homophobia Education in Public Schooling: A Canadian Case Study of Policy Implementation

SUMMARY

An 18-month study investigating the implementation of a Canadian anti-homophobia school policy found that such policies need to address homophobic ideas, institutional forms of homophobia and heterosexism, and individual expressions of homophobia. Teacher development is identical as an area in which Canadian policy implementation can be improved. More resources are needed to support the complex negotiations that educators must undertake when their professional and personal commitments to equity and human rights education collide with their own and others' personal and community religious beliefs about homosexuality.     

Regression Models and Risk Estimation for Mixed Discrete and Continuous Outcomes in Developmental Toxicology

Multivariate dose-response models have recently been proposed for developmental toxicity data to simultaneously model malformation incidence (a binary outcome), and reductions in fetal weight (a continuous outcome). In this and other applications, the binary outcome often represents a dichotomization of another outcome or a composite of outcomes, which facilitates analysis. For example, in Segment II developmental toxicology studies, multiple malformation types (i.e., external, visceral, skeletal) are evaluated on each fetus; malformation status may also be ordinally measured (e.g., normal, signs of variation, full malformation). A model is proposed is for fetal weight and multiple malformation variables measured on an ordinal scale, where the correlations between the outcomes and between the offspring within a litter are taken into account. Fully specifying the joint distribution of outcomes within a litter is avoided by specifying only the distribution of the multivariate outcome for each fetus and using generalized estimating equation methodology to account for correlations due to litter clustering. The correlations between the outcomes are required to characterize joint risk to the fetus, and are therefore a focus of inference. Dose-response models and their application to quantitative risk assessment are illustrated using data from a recent developmental toxicology experiment of ethylene oxide in mice.     

Effective Recruitment for Parenting Programs Within Ethnic Minority Communities

This article describes the results of a demonstration project which focused on exploring recruitment and retention of ethnic minority families to a parent training program aimed to prevent substance abuse among their children. The Parenting for Drug-Free Children project sought to deliver a curriculum to parents from several ethnic groups in an urban setting. The targeted ethnic communities were African American, Latino, Native American, and Samoan. The project successfully recruited diverse groups of families to participate in a drug prevention program, many of whom had never participated before in a parenting program. The identification of key individuals for recruiting and accessing networks of potential participants proved to be an effective means of recruitment.     

Alcohol- and drug-involved driving in the United States: methodology for the 2007 National Roadside Survey

This article describes the methodology used in the 2007 U.S. National Roadside Survey to estimate the prevalence of alcohol- and drug-impaired driving and alcohol- and drug-involved driving. This study involved randomly stopping drivers at 300 locations across the 48 continental U.S. states at sites selected through a stratified random sampling procedure. Data were collected during a 2-hr Friday daytime session at 60 locations and during 2-hr nighttime weekend periods at 240 locations. Both self-report and biological measures were taken. Biological measures included breath alcohol measurements from 9,413 respondents, oral fluid samples from 7,719 respondents, and blood samples from 3,276 respondents.     

Trait anger as a mediator of difficulties with emotion regulation and female-perpetrated psychological aggression

Recent research has demonstrated the devastating impact of female-perpetrated psychological aggression in intimate relationships broadly and dating relationships specifically. With the perpetration of psychological aggression in dating relationships occurring at shockingly high rates, prevention programming for dating violence should target this form of aggression. Toward this end, it is important to understand the antecedent conditions that increase one's risk for perpetrating psychological aggression. This study sought to examine two possible risk factors for perpetrating psychological aggression among female undergraduates (N = 145), namely, emotion regulation and trait anger. Findings showed that difficulties with emotion regulation and trait anger were associated with increased psychological aggression perpetration, and trait anger mediated the link between emotion regulation and psychological aggression. Implications of these findings for prevention programming and future research are discussed.     

Implications of Developmental Toxicity Study Design for Quantitative Risk Assessment

Standard experimental designs for conducting developmental toxicity studies typically include three- or four-dose levels in addition to a control group. Some researchers have suggested that designs with more exposure groups would improve dose-response characterization and risk estimation. Such proposals have not, however, been supported by the results of simulation studies, which instead back the use of fewer dose levels. This discrepancy is partly due to using a known dose–response pattern to generate data, making model choice obvious. While the carcinogenicity literature has explored implications of different study designs, little attention has been given to the role of design in developmental toxicity risk assessment (or noncancer toxicology in general). In this research, we explore the implications of various experimental designs for developmental toxicity by resampling data from a large study of 2,4,5-trichlorophenoxyacetic acid in mice. We compare the properties of benchmark dose (BMD) estimation for different design strategies by randomly selecting animals within particular dose groups from the entire 2,4,5-T database of over 77,000 birth outcomes to create smaller "pseudo-studies" that are representative of standard bioassay sample sizes. Our results show that experimental designs which include more dose levels have advantages in terms of risk characterization and estimation.     

The ecological effect of unemployment on the incidence of very low birthweight in Norway and Sweden

Little attention has been paid to the ecological effects of unemployment, despite strong theory suggesting that being socially or economically connected to unemployed persons can induce illness. Theory suggests, for example, that the labor market experience of adult males should affect maternal and infant health. We advance this line of inquiry by testing the hypothesis that quarterly increases in unemployment among Norwegian and Swedish males were associated with increased incidence of very low weight births from 1973 through 1995. Results support the hypothesis. We estimate that approximately 188 very low weight births could have been averted in Norway, and about 329 in Sweden, if quarterly increases in male unemployment had been constrained to the median over the 23-year period. Our findings imply that the social cost of unemployment may be underestimated by focusing on unemployment as an individual risk factor.     

The effect of movie portrayals on audience attitudes about nontraditional families and sexual orientation

This study examined the impact of motion pictures about the family on viewers' attitudes about family life and sexual orientation. Viewers were randomly assigned to view either Father of the Bride II (control group) or Object of My Affection (treatment group). Viewers' attitudes toward nontraditionalism and homosexuality were assessed before and after viewing their respective film. Treatment and control groups significantly differed in their attitudes toward nontraditionalism, but did not significantly differ in their attitudes toward homosexuals after viewing their respective films. However, the treatment group experienced more favorable attitudes toward homosexuals than the control group after viewing the film. Gender differences were also observed. Men were less tolerant of homosexuals and held fewer nontraditional beliefs about the family than women. Implications and discussion follow.
