Mechanisms of child behavior change in parent training: Comment on Weeland et al. (2018) / Theodore P. BEAUCHAINE in Development and Psychopathology, 30-4 (October 2018)
[article]
Titre : Mechanisms of child behavior change in parent training: Comment on Weeland et al. (2018) Type de document : Texte imprimé et/ou numérique Auteurs : Theodore P. BEAUCHAINE, Auteur ; Amy SLEP, Auteur Article en page(s) : p.1529-1534 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Recently in this journal, Weeland et al. () published a thought-provoking article reporting moderating effects of children's serotonin transporter-linked polymorphisms (5-HTTLPR) on negative parenting during prevention with the Incredible Years series. Participants were parents and young children of 387 families enrolled in the Observational Randomized Control Trial of Childhood Differential Susceptibility study. An equally important finding, which we focus on in this comment, involved null effects for all tests of parenting as a mediator of prevention-induced improvements in children's externalizing behavior. Although such findings may seem surprising, both confirmations of and failures to confirm parenting change as a mediator of child behavior change are common in the prevention and intervention literatures. In this comment, we explore likely reasons for heterogeneity in findings, including both moderators of treatment effect size and methods used to test mediation. Common moderators of prevention and intervention response to Incredible Years include dose, parenting problems at intake, high-risk versus clinical nature of samples, how parenting is measured, and whether child training is included with parent training. All of these moderators affect power to detect mediation. We then discuss conceptual criteria for testing mediation in randomized clinical trials, and problems with interpreting mediating paths in cross-lag panel models. Although the gene effect reported by Weeland et al. is important, their cross-lag panel models do not provide strong tests of parenting as a mediator of child behavior change. We conclude with recommendations for testing mediation in randomized clinical trials.

Titre : METHODOLOGICAL ARTICLE: A Brief Taxometrics Primer Type de document : Texte imprimé et/ou numérique Auteurs : Theodore P. BEAUCHAINE, Auteur Année de publication : 2007 Article en page(s) : p.654-676 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Taxometric procedures provide an empirical means of determining which psychiatric disorders are typologically distinct from normal behavioral functioning. Although most disorders reflect extremes along continuously distributed behavioral traits, identifying those that are discrete has important implications for accurate diagnosis, effective treatment, early identification of risk, and improved understanding of etiology. This article provides (a) brief descriptions of the conceptual bases of several taxometric procedures, (b) example analyses using simulated data, and (c) strategies for avoiding common pitfalls that are often observed in taxometrics research. To date, most taxometrics studies have appeared in the adult psychopathology literature. It is hoped that this primer will encourage interested readers to extend taxometrics research to child and adolescent populations.

[article]
Titre : A Monte Carlo evaluation of growth mixture modeling Type de document : Texte imprimé et/ou numérique Auteurs : Tiffany M. SHADER, Auteur ; Theodore P. BEAUCHAINE, Auteur Article en page(s) : p.1604-1617 Langues : Anglais (eng) Mots-clés : Computer Simulation Humans Models, Statistical Monte Carlo Method Monte Carlo growth mixture modeling latent classes longitudinal simulation Index. décimale : PER Périodiques Résumé : Growth mixture modeling (GMM) and its variants, which group individuals based on similar longitudinal growth trajectories, are quite popular in developmental and clinical science. However, research addressing the validity of GMM-identified latent subgroupings is limited. This Monte Carlo simulation tests the efficiency of GMM in identifying known subgroups (k = 1-4) across various combinations of distributional characteristics, including skew, kurtosis, sample size, intercept effect size, patterns of growth (none, linear, quadratic, exponential), and proportions of observations within each group. In total, 1,955 combinations of distributional parameters were examined, each with 1,000 replications (1,955,000 simulations). Using standard fit indices, GMM often identified the wrong number of groups. When one group was simulated with varying skew and kurtosis, GMM often identified multiple groups. When two groups were simulated, GMM performed well only when one group had steep growth (whether linear, quadratic, or exponential). When three to four groups were simulated, GMM was effective primarily when intercept effect sizes and sample sizes were large, an uncommon state of affairs in real-world applications. When conditions were less ideal, GMM often underestimated the correct number of groups when the true number was between two and four. Results suggest caution in interpreting GMM results, which sometimes get reified in the literature.

Titre : Multifinality in the development of personality disorders: A Biology × Sex × Environment interaction model of antisocial and borderline traits Type de document : Texte imprimé et/ou numérique Auteurs : Theodore P. BEAUCHAINE, Auteur ; Lisa GATZKE-KOPP, Auteur ; Daniel N. KLEIN, Auteur ; Sheila E. CROWELL, Auteur ; Christina M. DERBIDGE, Auteur Année de publication : 2009 Article en page(s) : p.735-770 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Although antisocial personality disorder (ASPD) is more common among males and borderline PD (BPD) is more common among females, some authors have suggested that the two disorders reflect multifinal outcomes of a single etiology. This assertion is based on several overlapping symptoms and features, including trait impulsivity, emotional lability, high rates of depression and suicide, and a high likelihood of childhood abuse and/or neglect. Furthermore, rates of ASPD are elevated in the first degree relatives of those with BPD, and concurrent comorbidity rates for the two disorders are high. In this article, we present a common model of antisocial and borderline personality development. We begin by reviewing issues and problems with diagnosing and studying PDs in children and adolescents. Next, we discuss dopaminergic and serotonergic mechanisms of trait impulsivity as predisposing vulnerabilities to ASPD and BPD. Finally, we extend shared risk models for ASPD and BPD by specifying genetic loci that may confer differential vulnerability to impulsive aggression and mood dysregulation among males and impulsive self-injury and mood dysregulation among females. Although the precise mechanisms of these sex-moderated genetic vulnerabilities remain poorly understood, they appear to interact with environmental risk factors including adverse rearing environments to potentiate the development of ASPD and BPD.

Titre : Neural responses to monetary incentives among self-injuring adolescent girls Type de document : Texte imprimé et/ou numérique Auteurs : Colin L. SAUDER, Auteur ; Christina M. DERBIDGE, Auteur ; Theodore P. BEAUCHAINE, Auteur Article en page(s) : p.277-291 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Rates of self-inflicted injury among adolescents have risen in recent years, yet much remains to be learned about the pathophysiology of such conduct. Self-injuring adolescents report high levels of both impulsivity and depression behaviorally. Aberrant neural responding to incentives, particularly in striatal and prefrontal regions, is observed among both impulsive and depressed adolescents, and may mark common vulnerability to symptoms of anhedonia, irritability, and low positive affectivity. To date, however, no studies have examined associations between central nervous system reward responding and self-injury. In the current study, self-injuring (n = 19) and control (n = 19) adolescent females, ages 13–19 years, participated in a monetary incentive delay task in which rewards were obtained on some trials and losses were incurred on others. Consistent with previous findings from impulsive and depressed samples, self-injuring adolescents exhibited less activation in both striatal and orbitofrontal cortex regions during anticipation of reward than did controls. Self-injuring adolescents also exhibited reduced bilateral amygdala activation during reward anticipation. Although few studies to date have examined amygdala activity during reward tasks, such findings are common among adults with mood disorders and borderline personality disorder. Implications for neural models of impulsivity, depression, heterotypic comorbidity, and development of both self-injury and borderline personality traits are discussed.
