Association between a marker for prenatal testosterone exposure and externalizing behavior problems in children / Jianghong LIU in Development and Psychopathology, 24-3 (August 2012)  

Public ISBD [article]  inDevelopment and Psychopathology > 24-3 (August 2012) . - p.771-82 Titre : Association between a marker for prenatal testosterone exposure and externalizing behavior problems in children Type de document : Texte imprimé et/ou numérique Auteurs : Jianghong LIU, Auteur ; Jill PORTNOY, Auteur ; Adrian RAINE, Auteur Année de publication : 2012 Article en page(s) : p.771-82 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Prenatal androgen exposure has been associated with aggressive behavior in adults. It is less clear whether this association holds for childhood externalizing behavior. This study tests the hypothesis that increased prenatal androgen exposure is associated with aggressive behavior and attention problems in childhood. The ratio of the length of the second finger digit relative to the fourth digit, which is a marker for prenatal testosterone exposure, was assessed in 239 male and female fifth grade schoolchildren from Jintan, China, together with parent and teacher ratings of aggression and attention problems. Increased aggression and attention problems were both significantly associated with a lower ratio of the length of the second finger digit relative to the fourth digit ratios in boys but not girls. The effects remained significant after controlling for early adversity. These findings are the first to establish a relationship between an indirect indicator of fetal androgen exposure and any child psychopathology in Chinese children, and the observed effect size in boys was stronger than in male adults in Western studies. The results provide limited cross-cultural support for the importance of prenatal androgen exposure in contributing to the development of externalizing behavior problems in children, and they suggest that such effects may be specific to boys who may be relatively more vulnerable to early prenatal influences.

Item ratings were aggregated into scores on syndromes; Diagnostic and Statistical Manual of Mental Disorders-oriented scales; a Stress Problems scale; and Internalizing, Externalizing, and Total Problems scales. Effect sizes for scale score differences among the 24 societies ranged from small to medium (3-12%). Although societies differed greatly in language, culture, and other characteristics, Total Problems scores for 18 of the 24 societies were within 7.1 points of the omnicultural mean of 33.3 (on a scale of 0-198). Gender and age differences, as well as gender and age interactions with society, were all very small (effect sizes < 1%). Across all pairs of societies, correlations between mean item ratings averaged .78, and correlations between internal consistency alphas for the scales averaged .92, indicating that the rank orders of mean item ratings and internal consistencies of scales were very similar across diverse societies.

Nutritional supplementation to reduce child aggression: a randomized, stratified, single-blind, factorial trial / Adrian RAINE in Journal of Child Psychology and Psychiatry, 57-9 (September 2016)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 57-9 (September 2016) . - p.1038-1046 Titre : Nutritional supplementation to reduce child aggression: a randomized, stratified, single-blind, factorial trial Type de document : Texte imprimé et/ou numérique Auteurs : Adrian RAINE, Auteur ; Rose A. CHENEY, Auteur ; Ringo HO, Auteur ; Jill PORTNOY, Auteur ; Jianghong LIU, Auteur ; Liana SOYFER, Auteur ; Joseph HIBBELN, Auteur ; Therese S. RICHMOND, Auteur Article en page(s) : p.1038-1046 Langues : Anglais (eng) Mots-clés : Aggression  omega-3  cognitive behavioral therapy  reactive  callous  nutrition  externalizing Index. décimale : PER Périodiques Résumé : Background While some studies suggest that nutritional supplementation may reduce aggressive behavior in children, they have not examined whether its efficacy may be enhanced in conjunction with other treatment approaches. This study tests the hypothesis that a nutritional supplementation of omega-3, multivitamins, and minerals over 3 months, combined with cognitive behavior therapy, will reduce childhood aggression. Methods In this randomized, single-blind, stratified, factorial trial, a high-risk community sample of 290 children aged 11–12 years were randomized into Nutrition only, cognitive behavioral therapy (CBT) only, Nutrition + CBT, and Control groups. The primary outcome measures of child- and parent-reported aggressive and antisocial behavior were collected at 0 months (baseline), 3 months (end of treatment), 6 months (3 months posttreatment), and 12 months (9 months posttreatment). The trial (‘Healthy Brains & Behavior: Understanding and Treating Youth Aggression (HBB)’ was registered at ClinicalTrials.gov at https://clinicaltrials.gov/ct2/show/NCT00842439 Results For child self-reports, children in the Nutrition only group showed reduced externalizing behavior compared to Controls at 3 months. At 6 months, the Nutrition + CBT group scored lower on externalizing behavior compared to both CBT only and Control groups. Findings were more in evidence for an Aggressive-Reactive form of antisocial behavior than for a Callous-Proactive form. Effect sizes were in the small-to-medium range (d = ?.33 to ?.37). Group differences were not sustained 9 months posttreatment, and no other effects were significant. Conclusions Findings provide some limited support for the efficacy of omega-3, vitamin, and mineral supplementation in reducing aggressive behavior in children, and represent the first evaluation of nutritional supplements in conjunction with CBT.

Reduction in behavior problems with omega-3 supplementation in children aged 8–16 years: a randomized, double-blind, placebo-controlled, stratified, parallel-group trial / Adrian RAINE in Journal of Child Psychology and Psychiatry, 56-5 (May 2015)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 56-5 (May 2015) . - p.509-520 Titre : Reduction in behavior problems with omega-3 supplementation in children aged 8–16 years: a randomized, double-blind, placebo-controlled, stratified, parallel-group trial Type de document : Texte imprimé et/ou numérique Auteurs : Adrian RAINE, Auteur ; Jill PORTNOY, Auteur ; Jianghong LIU, Auteur ; Tashneem MAHOOMED, Auteur ; Joseph R.

This study tests the hypothesis that omega-3 supplementation over 6 months will reduce behavior problems in children both at the end of treatment and at 6 months post treatment. Methods In this randomized, double-blind, placebo-controlled, stratified, parallel-group trial, a community sample of 8–16 year old children were randomized into a treatment group (N = 100) and a placebo-control group (N = 100). The supplementation consisted of a fruit drink containing 1 g/day of omega-3 or a placebo consisting of the same fruit drink without omega-3. Participants, caregivers, and research assistants were blinded to group assignment. The primary outcome measures of externalizing and internalizing behavior problems were reported by both caregivers and their children in a laboratory setting at 0 months (baseline), 6 months (end of treatment) and 12 months (6 months post treatment), together with the secondary outcome measures of parental antisocial behavior. Data were analyzed on an intention-to-treat basis including all participants. Trial registration: ClinicalTrials.gov: http://clinicaltrials.gov/ct2/show/NCT02016079?term=mauritius&rank=2 Results Significant group × time interactions were observed with the treatment group showing long-term improvements in child behavior problems. The average posttreatment effect size was d = ?.59. Effects were documented for parent reports, but with the exception of proactive and reactive aggression, child-report data were nonsignificant. Parents whose children took omega-3 showed significant posttreatment reductions in their own antisocial and aggressive behavior. This improvement in caregiver behavior partly mediated the improvements observed in child behavior. Conclusions Findings provide initial evidence that omega-3 supplementation can produce sustained reductions in externalizing and internalizing behavior problems. Results are the first to report improvements in caregiver behavior, and to establish this improvement as a part-mechanism for the efficacy of omega-3.
