Previous research has also neglected the dimensional effects of psychological control on child bullying development. This study examined two psychological control dimensions, love withdrawal and guilt induction, and their effects on children's bullying aggressive behavior using a longitudinal design. Participants were first-generation Chinese American mothers (N = 133; mean age [Mage] = 37.82) and their preschool children (Mage = 4.48). Chinese immigrant mothers reported their psychologically controlling parenting and teachers rated children's bullying aggressive behaviors in the school setting. Confirmatory factor analyses were conducted to establish the psychometric properties and cross-wave measurement equivalence of the study constructs. Cross-lagged structural equation modeling analysis indicated that maternal love withdrawal prospectively predicted more bullying aggressive behavior, whereas guilt induction predicted less bullying aggressive behavior in children 6 months later. These results held after controlling for the initial level of children's problem behaviors and demographic variables (child age, gender, and maternal education). For child effects, child bullying aggressive behavior predicted more maternal guilt induction over time but not love withdrawal. Our findings highlight the importance of construct specificity and cultural context in understanding associations between parenting and child development.

Oral probiotic administration during pregnancy prevents autism-related behaviors in offspring induced by maternal immune activation via anti-inflammation in mice / X. WANG in Autism Research, 12-4 (April 2019)  

Public ISBD [article]  inAutism Research > 12-4 (April 2019) . - p.576-588 Titre : Oral probiotic administration during pregnancy prevents autism-related behaviors in offspring induced by maternal immune activation via anti-inflammation in mice Type de document : Texte imprimé et/ou numérique Auteurs : X. WANG, Auteur ; J. YANG, Auteur ; H. ZHANG, Auteur ; J. YU, Auteur ; Z. YAO, Auteur Article en page(s) : p.576-588 Langues : Anglais (eng) Mots-clés : anti-inflammation  autism spectrum disorders  interleukin 17a  interleukin 6  maternal immune activation  probiotics Index. décimale : PER Périodiques Résumé : Maternal immune activation (MIA) is associated with an increased risk for autism spectrum disorders (ASD) in offspring. Animal experiments have found that interleukin 6 (IL-6) and IL-17a are key cytokines in the induction of ASD by MIA. Moreover, probiotics were verified to inhibit the production of proinflammatory cytokines. Therefore, we investigated whether the administration of oral probiotics during pregnancy might protect the offspring that have suffered MIA from developing ASD. Probiotics were orally administered to pregnant mice with/without the simultaneous administration of Poly(I:C). We found that oral probiotics prevented the ASD-like behaviors induced by MIA in offspring. Furthermore, oral probiotics prevented the MIA-induced increases in the IL-6 and IL-17a levels in both maternal serum and fetal brains, parvalbumin positive (PV(+) ) neuron loss, and the decrease in the gamma-aminobutyric acid levels in the prefrontal cortex of adult offspring. This work suggests that administering oral probiotics during pregnancy may help decrease the risk of ASD following MIA during pregnancy. Autism Res 2019, 12: 576-588. (c) 2019 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: Interleukin 6 (IL-6) and IL-17a are key cytokines in the maternal immune activation (MIA)-induced autism spectrum disorders (ASD). Based on emerging evidence that probiotics can inhibit the production of proinflammatory cytokines, we found that oral probiotics prevented MIA-induced ASD-like behaviors in offspring. This work suggested that oral probiotics during pregnancy may be an effective means for decreasing the incidence of ASD in offspring.
