Meta‐CART: A tool to identify interactions between moderators in meta‐analysis

In the framework of meta‐analysis, moderator analysis is usually performed only univariately. When several study characteristics are available that may account for treatment effect, standard meta‐regression has difficulties in identifying interactions between them. To overcome this problem, meta‐CART has been proposed: an approach that applies classification and regression trees (CART) to identify interactions, and then subgroup meta‐analysis to test the significance of moderator effects. The previous version of meta‐CART has its shortcomings: when applying CART, the sample sizes of studies are not taken into account, and the effect sizes are dichotomized around the median value. Therefore, this article proposes new meta‐CART extensions, weighting study effect sizes by their accuracy, and using a regression tree to avoid dichotomization. In addition, new pruning rules are proposed. The performance of all versions of meta‐CART was evaluated via a Monte Carlo simulation study. The simulation results revealed that meta‐regression trees with random‐effects weights and a 0.5‐standard‐error pruning rule perform best. The required sample size for meta‐CART to achieve satisfactory performance depends on the number of study characteristics, the magnitude of the interactions, and the residual heterogeneity.     

Validation of Self-Report Impairment Measures for Section III Obsessive–Compulsive and Avoidant Personality Disorders

This study examined the validity of newly developed disorder-specific impairment scales (IS), modeled on the Level of Personality Functioning Scale, for obsessive–compulsive (OCPD) and avoidant (AvPD) personality disorders. The IS focused on content validity (items directly reflected the disorder-specific impairments listed in DSM-5 Section III) and severity of impairment. A community sample of 313 adults completed personality inventories indexing the DSM-5 Sections II and III diagnostic criteria for OCPD and AvPD, as well as measures of impairment in the domains of self- and interpersonal functioning. Results indicated that both impairment measures (for AvPD in particular) showed promise in their ability to measure disorder-specific impairment, demonstrating convergent validity with their respective Section II counterparts and discriminant validity with their noncorresponding Section II disorder and with each other. The pattern of relationships between scores on the IS and scores on external measures of personality functioning, however, did not indicate that it is useful to maintain a distinction between impairment in the self- and interpersonal domains, at least for AvPD and OCPD.     

Alcohol Intoxication and Metamemory: Little Evidence that Moderate Intoxication Impairs Metacognitive Monitoring Processes

There is minimal research on metacognition in alcohol‐intoxicated participants. Study 1 examined metacognition across sober, intoxicated, and placebo groups, with the intoxicated group's breath alcohol concentration reaching 0.074 g/210 L on average immediately prior to the metacognition task. Participants answered cued recall general knowledge questions and provided confidence ratings and feeling‐of‐knowing judgments. They then completed a recognition (i.e., multiple choice) version of the same task, indicating an answer and a confidence rating for each question. Findings suggest that metacognitive accuracy generally did not vary across intoxication levels, although the control group's retrospective confidence judgments better discriminated between accurate and inaccurate responses than the alcohol groups in the recognition task. Study 2 surveyed academic psychologists about their expectations regarding the relation between alcohol and metacognition. Study 1's results were counter to their expectations, as respondents generally predicted a relation would be present. We discuss the implications for alcohol and memory.Copyright © 2017 John Wiley & Sons, Ltd.     

Every Child Still Matters: interdisciplinary approaches to the spirituality of the child

Abstract

Ten years ago, I was a researcher with the Evaluation of Children’s Trusts which examined a key aspect of U.K. government policy, Every Child Matters. Every Child Matters was partly a response to Lord Laming’s 2003 report into the murder of 8-year old Victoria Climbié, which concluded that children’s services needed to be better integrated to avoid such tragedies in the future. Children’s Trusts were regional hubs, set-up across England to facilitate integrated professional practice; but Every Child Matters was bigger than this because it set out a policy vision for rethinking the child as a whole person. At the time, I was struck by the absence of any reference to spirituality in this new holistic view of the child, and this led me to write an article which was published in 2006 entitled, ‘Every Child Matters and children’s spiritual rights: does the new holistic approach to children’s care address children’s spiritual well-being?’.

This article was originally a keynote talk at the 2016 International Conference on Children’s Spirituality with the theme Spirituality and the whole child: interdisciplinary approaches, and this provided the opportunity both to see where we are now with integrated working for children and young people more generally, and to focus our attention on interdisciplinary approaches to children’s spirituality and the whole child in particular. The article begins by summarising some of the current thinking spirituality, the whole child and interdisciplinary working. The article then goes on to consider a long-standing concern of mine, and one which was highlighted in my 2006 article, which is what we intend to mean – collectively, as academics and professional practitioners concerned with children’s (and adults’) spirituality – when we use the term ‘spirituality’ in the professional context. In my view, it is time to stop stating that spirituality is hard to define, and come to an agreement about what we mean when we use it. Interdisciplinary approaches to children’s (and adults’) spirituality, and holistic approaches to the child (and adult), will not be successful unless there is a clear, shared agreement about what we mean, and the article ends with suggestions for ways forward.     

Preliminary evidence of the impact of early childhood maltreatment and a preventive intervention on neural patterns of response inhibition in early adolescence

Maltreated youths in foster care often experience negative developmental and psychological outcomes, which have been linked with poor response inhibition. Recent evidence suggests that childhood maltreatment is also associated with alterations in the neural circuitry underlying response inhibition. However, a burgeoning line of research has begun to explore the mitigating effects of preventive interventions on neural functioning. The current study used event‐related functional magnetic resonance imaging to explore the impact of early childhood maltreatment and a preventive intervention on response inhibition in early adolescence. Thirty‐six demographically similar adolescents (ages 9–14 years) completed a Go/NoGo task. The sample included nonmaltreated adolescents (n = 14) and maltreated adolescents who were in foster care as preschoolers and randomly assigned to receive services as usual (n = 11) or a preventive intervention, Multidimensional Treatment Foster Care for Preschoolers (n = 11). The groups demonstrated similar behavioral performance but significantly different neural patterns. The maltreated adolescents who received services as usual demonstrated subcortical hypoactivity during successful response inhibition and subcortical hyperactivity during unsuccessful response inhibition. In contrast, the nonmaltreated adolescents and maltreated adolescents who received the intervention exhibited strikingly similar neural patterns during successful response inhibition, but the maltreated adolescents who received the intervention demonstrated prefrontal hypoactivity during unsuccessful response inhibition. These findings offer preliminary evidence that early childhood maltreatment alters the neural patterns underlying response inhibition in early adolescence and that participating in a preventive intervention could mitigate maltreatment‐related effects on these neural systems.     

DNA Testing for Family Reunification in Canada: Points to Consider

Countries have adopted different laws, policies, and practices that allow immigration officers to request in certain cases DNA tests to confirm biological relationships in the context of family reunification. In Canada, Citizenship and Immigration Canada has adopted a policy of suggesting DNA testing only as a last resort in cases where no documentary evidence has been submitted or where the evidence provided is deemed unsatisfactory. However, in practice, there have been concerns on the increasing use of DNA tests in family reunification processes of nationals from certain regions including Africa, Asia, and Latin America. Moreover, the Immigration and Refugee Protection Regulations (IRPR) presents a biological definition of family as a determinant of parenthood in the context of family reunification that is inconsistent with the psychosocial definition used in provincial family laws. Although there are cases that can justify the request for DNA tests, there are also significant social, legal, and ethical issues, including discrimination and unfair practices, raised by this increasing use of genetic information in immigration. This policy brief identifies points to consider for policymakers regarding the use of DNA testing in Canadian family reunification procedures. These include (1) the need to refine the policy of “using DNA testing as a last resort” and its implementation, (2) the need to modify the definition of “dependent child” under the IRPR to reflect the intrinsic reality of psychosocial family ties, and (3) the importance of conducting more research on the use of DNA testing in other immigration contexts.     

The moderating effect of parental warmth on the association between spanking and child aggression: a longitudinal approach

Using data from the Early Head Start Research and Evaluation Study, this study analysed the stability of child aggressive behaviour beginning in infancy and tested whether spanking when the child was 36 months was associated with aggressive child behaviour among three ethnic groups and whether maternal warmth moderated the effect of spanking on aggressive behaviour in each ethnic group at 36 months, after controlling for earlier aggressive behaviour. Participants included 693 Hispanic parent–child dyads, 1013 African‐American dyads and 1086 Caucasian dyads who met qualifications for participation in the Early Head Start programme. Findings suggest that infant temperament was associated with aggressive behaviour at 24 and 36 months and that child aggression remained stable. Among the three ethnic groups, spanking was only associated with aggressive behaviour for children who had Caucasian mothers and maternal warmth did not moderate the effect of spanking on aggressive behaviour.

Seeking the perfect balance: Perfectionism and work–family conflict

This study considers the relationship between perfectionism and perceptions of work–family conflict. A situational component to perfectionism was found, with higher standards and a higher perceived discrepancy between standards and performance at home versus at work. Findings suggest perfectionism predicts work–family conflict, beyond the effects of the Big Five, trait affectivity and achievement. Further, findings indicate those with adaptive perfectionism (AP; work and home) tend to have lower strain and time‐based family interfering with work and lower behaviour‐based work interfering with family, compared with maladaptive perfectionists (home) and non‐perfectionists (work and home). Gender differences were found and considered in a more exploratory manner.
