Maternal Emotion Socialization: The Contribution of Inhibited Behaviour and Mothers' Dissatisfaction with the Parent–Child Relationship

In the present study, we examined the associations between children's inhibited behaviour, mothers' dissatisfaction with the parent–child relationship and mothers' self‐reported reactions to children's emotions. Fifty‐three mother–child dyads visited the laboratory, and mothers completed questionnaires about child temperament and emotion socialization. Maternal stress stemming from dissatisfaction with the parent–child relationship was negatively predictive of mothers' supportive reactions to happiness. In addition, the interaction between children's inhibited behaviour and parent–child relationship dissatisfaction significantly predicted mothers' supportive reactions to children's fear; specifically, mothers who reported the highest levels of dissatisfaction in their relationship with their children and had children who exhibited low levels of inhibition reported the lowest levels of supportive responses to their children's fear. Importantly, mothers reported the highest levels of supportive reactions to children's fear when their children were low in inhibition, and they reported low levels of dissatisfaction in their relationship with their child.

Not every credible interval is credible: Evaluating robustness in the presence of contamination in Bayesian data analysis

As Bayesian methods become more popular among behavioral scientists, they will inevitably be applied in situations that violate the assumptions underpinning typical models used to guide statistical inference. With this in mind, it is important to know something about how robust Bayesian methods are to the violation of those assumptions. In this paper, we focus on the problem of contaminated data (such as data with outliers or conflicts present), with specific application to the problem of estimating a credible interval for the population mean. We evaluate five Bayesian methods for constructing a credible interval, using toy examples to illustrate the qualitative behavior of different approaches in the presence of contaminants, and an extensive simulation study to quantify the robustness of each method. We find that the “default” normal model used in most Bayesian data analyses is not robust, and that approaches based on the Bayesian bootstrap are only robust in limited circumstances. A simple parametric model based on Tukey’s “contaminated normal model” and a model based on the t-distribution were markedly more robust. However, the contaminated normal model had the added benefit of estimating which data points were discounted as outliers and which were not.     

Bioethics, Christian charity and the view from no place.

This essay contrasts the notions of charity employed by Traditional Christianity and by liberal cosmopolitan bioethics, arguing that: (1) bioethics attempts to reconstruct the notion of charity in a manner that is caustic to the Traditional Christian moral vision, (2) Christians are, on the whole, more charitable than proponents of bioethics' reconstructed view (even given the standards of the latter), and (3) the theistically oriented conception of charity employed by Traditional Christianity cannot be expressed in bioethics' purportedly neutral public vocabulary. The upshot is that, in the name of neutrality and pluralism, liberal cosmopolitan bioethicists seek to impose an impoverished moral vocabulary that reflects liberal cosmopolitan ideology while excluding input from Traditional Christianity and other non-liberal-humanistic moral visions.     

Cognition at risk: Gestalt/feature-intensive processing, attention deficit, and substance abuse

Attention deficit hyperactive disorder (ADHD) is associated with elevated levels of substance abuse, but the cognitive linkages involved have been little explored. The present study builds upon earlier work showing that more gestalt, as opposed to feature-intensive, styles of processing are conductive to substance abuse, especially in those with ADHD symptoms. The work reported here indicates that a protective factor against substance abuse may lie in relatively efficient heuristic processing, especially synthetic or inferential heuristic processing, but further demonstrates that those with ADHD symptoms tend to have poorer abilities in this regard, even at the subclinical, nondiagnosed level. Results are discussed in terms of the gestalt/featureintensive processing theory of cognition.     

Attention problems and executive functions in children with spina bifida and hydrocephalus.

This study addressed the incidence of Attention-Deficit/Hyperactivity Disorder (ADHD) subtypes in children with spina bifida meningomyelocele and shunted hydrocephalus (SBH) as well as differences in executive functions among these subtypes. Parent rating scales revealed that 31% of the group with SBH could be identified with AD/HD, mostly the Inattentive type (23%). The group with SBH differed from normal controls on cognitive measures of executive functions, but subtype differences were not significant. Multivariate tests showed that children with SBH were rated with greater difficulties on the Behavior Rating Inventory of Executive Function (BRIEF) compared to controls; those with SBH and any subtype of ADHD differed from those with SBH and no ADHD; and those with ADHD (Combined Type) differed significantly from those with ADHD (Predominantly Inattentive Type). Subtype differences on univariate tests in the latter comparison were significant on the BRIEF Inhibit scale, showing more disinhibition in those with SBH and ADHD (Combined Type), but no significant differences were apparent on the BRIEF Sustain, Shift, and Initiate scales. The results show that the incidence of ADHD in children with SBH exceeds the population rate, is represented by problems with inattention rather than with impulsivity and hyperactivity; and that as with non-brain injured individuals, subtype differences in cognitive function remain to more clearly delineated.     

From beliefs to behavior: the mediating role of hostile response selection in predicting aggression

This study evaluated the complementary roles that aggressive normative beliefs and hostile response selections play in predicting adolescents' aggressive behavior. Self‐, peer‐, and teacher‐reported data were collected from 2003 young adolescents from a variety of ethnic backgrounds (Black, Latino, Asian, White) during the fall of their sixth grade year to test the hypothesis that adolescents' hostile response selections mediate the association between their normative beliefs and aggressive reputations among their peers and teachers. Structural equation modeling analyses supported our hypothesis, and the model was found to be consistent across both gender and ethnicity. The results suggest that even though gender and ethnic differences in average levels of aggressive cognitions and behavior exist, the general process linking cognitions and behaviors is the same for all young adolescents.

Toward a hierarchical model of criminal thinking: evidence from item response theory and confirmatory factor analysis

Item response theory (IRT) methods were applied to items from the 80-item Psychological Inventory of Criminal Thinking Styles (PICTS; G. D. Walters, 1995) to determine how well they measure the latent trait of criminal thinking in a group of 2,872 male medium security prison inmates. Preliminary analyses revealed that the 64 PICTS thinking style items, 32 PICTS proactive criminal thinking items, and 24 PICTS reactive criminal thinking items were sufficiently unidimensional to meet the local independence requirements of IRT. The PICTS was fitted to a 2-parameter logistic-graded response IRT model, the results of which showed that the 8 items measuring denial of harm (Sentimentality) displayed weak discrimination (a < 0.5), whereas most of the proactive and reactive items displayed moderate to good discrimination (a > 1.0). Information function analysis revealed that all 3 components of a hierarchical model of criminal thinking--PICTS total scale, PICTS proactive factor, and PICTS reactive factor--displayed greater precision at higher rather than lower levels of the trait dimension. The study findings indicate that items from the PICTS Sentimentality scale do a poor job of measuring general criminal thinking, whereas items from the other 7 PICTS thinking style scales provide their most precise estimates at the upper end of the trait dimension.     

Efficacy of a Self-Administered Home-Based Parent Intervention on Parenting Behaviors for Preventing Adolescent Substance Use

A growing body of literature suggests that parenting practices characterized by careful monitoring, firm and consistent limit setting, and nurturing communication patterns with children are protective against adolescent substance use and other problem behaviors. Family-based prevention programs that promote these behaviors can be an effective way to prevent adolescent substance use. However, low participation rates remain problematic for many such programs, particularly programs that require parents to attend scheduled meetings outside the home. The purpose of this study was to determine the efficacy of a newly developed substance use prevention program when self-administered at home by parents of middle school students. As part of a randomized trial, 338 parents of middle school students either received the parent prevention program or served as control group participants. Parents completed self-report surveys at home that assessed parenting behaviors at pre-test, post-test, and one-year follow-up time points. A series of mixed model ANCOVAs were conducted, examining the post-test and one-year follow-up means for the parent outcomes, controlling for pre-test levels on these outcomes. Analyses showed that at the post-test assessment, intervention parents reported significant increases relative to controls in appropriate role modeling, disciplinary practices, family communication, and parental monitoring skills. At the one-year follow-up assessment, intervention effects on family communication skills remained significant and effects on parental role modeling were marginally significant. This study shows that a theoretically rich prevention program can be effectively self-administered by parents at home and improve key parenting skills that have been shown to prevent adolescent substance use.
