The Coping with Children's Negative Emotions Scale (CCNES) is a widely used measure of parent emotion socialization; however, it is a lengthy measure and it is unclear whether all items are appropriately aligned with, and fully capture, the underlying constructs. We aimed to examine content validity of the CCNES, evaluate the theoretical alignment between the CCNES and Gottman, Katz and Hooven's meta-emotion theory, and develop two short-forms. Participants were parents of children aged 4 to 10 years (N = 937) from the longitudinal study the Child and Parent Emotion Study (https://bmjopen.bmj.com/content/10/10/e038124). Content experts qualitatively evaluated parent-report items of the CCNES and additional items that measured empathy. Nineteen of the 84 items were found to not align with the meta-emotion theory. The latent structures of the CCNES and empathy subscales were quantitatively evaluated via confirmatory factor analysis. Items with poor psychometric properties were subsequently removed. An 18-item short-form (three emotion coaching subscales, three emotion dismissing subscales) and 6-item brief short-form (one emotion coaching subscale, one emotion dismissing subscale) with strong psychometric properties were created using a calibration sample (n = 468, that is, 50% of N = 937) and cross-validated with a validation sample. The short-form CCNES measures provide viable, theoretically consistent alternatives to the original CCNES measure. [ABSTRACT FROM AUTHOR]

Purpose: Maternal psychological distress and mother-infant bonding problems each predict poorer offspring outcomes. They are also related to each other, yet the extensive literature reporting their association has not been meta-analysed. Methods: We searched MEDLINE, PsycINFO, CINAHL, Embase, ProQuest DTG, and OATD for English-language peer-reviewed and grey literature reporting an association between mother-infant bonding, and multiple indicators of maternal psychological distress. Results: We included 133 studies representing 118 samples; 99 samples (110,968 mothers) were eligible for meta-analysis. Results showed concurrent associations across a range of timepoints during the first year postpartum, between bonding problems and depression (r =.27 [95% CI 0.20, 0.35] to r =.47 [95% CI 0.41, 0.53]), anxiety (r =.27 [95% CI 0.24, 0.31] to r =.39 [95% CI 0.15, 0.59]), and stress (r =.46 [95% CI 0.40, 0.52]). Associations between antenatal distress and subsequent postpartum bonding problems were mostly weaker and with wider confidence intervals: depression (r =.20 [95% CI 0.14, 0.50] to r =.25 [95% CI 0.64, 0.85]), anxiety (r =.16 [95% CI 0.10, 0.22]), and stress (r =.15 [95% CI − 0.67, 0.80]). Pre-conception depression and anxiety were associated with postpartum bonding problems (r = − 0.17 [95% CI − 0.22, − 0.11]). Conclusion: Maternal psychological distress is associated with postpartum mother-infant bonding problems. Co-occurrence of psychological distress and bonding problems is common, but should not be assumed. There may be benefit in augmenting existing perinatal screening programs with well-validated mother-infant bonding measures. [ABSTRACT FROM AUTHOR]

Purpose: In this study pupillometry was used to investigate the allocation of attentional resources associated with sentence comprehension in children with and without specific language impairment (SLI). Method: Eighteen children with SLI (age: M = 6.4 years) and 18 typically developing (TD) children (age: M = 6.3 years) participated in the study. A sentence comprehension task was presented that comprised items designated as easy or hard. Easy sentences contained 4 or 5 words, and hard sentences contained 6 or 7 words. Results: For the TD group, pupil size was significantly larger when comprehending hard sentences compared with easy sentences. There was no effect of sentence difficulty on pupil size in the SLI group. Comparisons between groups revealed pupil sizes for the SLI group were significantly larger than those for the TD group for easy sentences. There were no group differences for the hard sentences. Conclusion: In TD children, pupillometry was sensitive to the attentional demands associated with sentence comprehension. Between-subjects comparisons indicated that the TD group allocated less attention than did the children with SLI for the easy sentences but not for the hard sentences. This study provides evidence of attentional differences between children with SLI and TD children under conditions of low processing demands., Children with specific language impairment (SLI) have below age-appropriate language skills in the absence of an identifiable cause (American Psychiatric Association, 2013; World Health Organization, 1992). The spoken language of [...]

This paper aims to report an enhanced mechanistic analytical model to account for the geometry of a concentric cylinder structure, the effect of an elastic bonding layer, and mechanical boundary conditions on the magnetoelectric response. The elastic properties and the geometry of the bonding layer were added into the magneto-electro-elastic effective media theory by modifying the continuity condition through the introduction of a normalized stiffness parameter. Results from this investigation can be applied to the development of efficient energy harvesters or frequency-consistent magnetic field sensors by manipulating the mechanical and bonding conditions.

Background: This study assessed the extent to which women's preconception binge drinking, tobacco use and cannabis use, reported prospectively in adolescence and young adulthood, predicted use of these substances during pregnancy and at 1 year postpartum. Methods: Data were pooled from two intergenerational cohort studies: the Australian Temperament Project Generation 3 Study (395 mothers, 691 pregnancies) and the Victorian Intergenerational Health Cohort Study (398 mothers, 609 pregnancies). Alcohol, tobacco and cannabis use were assessed in adolescence (13–18 years), young adulthood (19–29 years) and at ages 29–35 years for those transitioning to parenthood. Exposures were weekly or more frequent preconception binge drinking (5 + drinks in one session), tobacco use and cannabis use. Outcomes were any alcohol, tobacco and cannabis use prior to awareness of the pregnancy, after awareness of pregnancy (up to and including the third trimester pregnancy) and at 1 year postpartum. Results: Frequent preconception binge drinking, tobacco use and cannabis use across both adolescence and young adulthood were strong predictors of continued use post-conception, before and after awareness of the pregnancy and at 1 year postpartum. Substance use limited to young adulthood also predicted continued use post-conception. Conclusions: Persistent alcohol, tobacco use and cannabis use that starts in adolescence has a strong continuity into parenthood. Reducing substance use in the perinatal period requires action well before pregnancy, commencing in adolescence and continuing into the years before conception and throughout the perinatal period.
