Identifying children at the risk of developmental delay can improve their long-term prognosis. In this case--control study, mothers and infants aged 6--18 months referred to healthcare centres affiliated with Qazvin University of Medical Sciences were recruited from August to December 2017. The sample size consisted of 197 individuals in…

We aimed to evaluate the validity of the Ages and Stages Questionnaires Edition 3 (ASQ-3) and the MacArthur communicative development inventory (CDI) as a screening measure for children at risk of language development delay in western rural China, by comparing them to the Bayley Scales of Infant and Toddler Development (BSID-III). We administered…

Aim: To investigate developmental trajectories in early childhood and predictors of class assignment. Methods: Data were available for Gen2 infants at 12 (n = 2275), 24 (n = 1845) and 36 (n = 2110) months of age in the Raine Study. Latent growth class analysis was used to identify developmental trajectories based on the Ages and Stages…

Substantial evidence endorses the early assessment of cognitive development to promote children's developmental health and well-being. Especially in the Brazilian context, there is a paucity of standardized screening and assessment tools with normative data to evaluate young children. This study provided initial reliability and validity evidence…

Socioeconomic disparities in early language are widespread and have long-lasting effects. The aim of this study is to investigate when social gaps in language problems arise and how they change across the first years of schooling. We address this question in two large longitudinal Norwegian datasets: the Behavior Outlook Norwegian Developmental…

Maternal singing is considered vital to infant well-being. This study focuses on vocal emotion expressions in infant-directed singing among mothers in war conditions. It examines the questions: (a) how traumatic war events and mental health problems are associated with the content and valence of vocal emotion expressions and (b) how these emotion…

Preterm birth consequences may lead to developmental deficits, psychiatric disorders and may also cause parental mental health problems. Our aim was to describe quality of life and internalizing-externalizing behaviours of preterm children at 2 years regarding parental mental health. 112 mothers of preterm children provided the following…

This mixed two-way experimental, cross-sectional study investigated fast-mapping (FM) of novel nouns and verbs in 63 Persian-speaking toddlers aged 30 months, including 31 late-talking (LT) and 32 typically developing (TD) matched with respect to age and maternal education. Toddlers were classified as LT if they had limited expressive vocabulary…

This study examined the unique relations between multiple sources (i.e., mothers, teachers, and siblings) of perceived daily autonomy support and psychological control and children's basic psychological needs and well-being. During 5 consecutive days, 2 children from 154 families (M[subscript age] youngest child = 8.54 years; SD = 0.89 and…

Fragmented sleep is common in infancy. Although night awakening is known to decrease with age, in some infants night awakening is more persistent and continues into older ages. However, the influence of fragmented sleep on development is poorly known. In the present study, the longitudinal relationship between fragmented sleep and psychomotor…

"Women's Mental Health Questionnaire" (W-MHQ) assesses females' adult mental health concerns, and examines their associations with specified father-daughter childhood relationships. Presented are W-MHQ item and scale development, and psychometric findings drawn from factor analyses, reliability assessments, and validation processes. For…

The present study investigated how changes in specific dimensions of the parent-adolescent relationship predict adolescent engagement in sexual intercourse and oral sex. Longitudinal data from 1,364 participants in the National Institute of Child Health and Human Development (NICHD) Study of Early Child Care and Youth Development were gathered at…

Background: Recent research suggests that adults and children with anxiety disorders have a particular set of metacognitive beliefs and strategies. Knowing whether parents' metacognitions, beliefs and behaviors are associated with their children's metacognitions is important for understanding how anxiety-related metacognitions and clinical anxiety…

A community sample of 192 parents reported on their children's restricted and repetitive behaviors (RRBs) at mean ages 15 months (N = 138), 26 months (N = 191), and 77 months (N = 125) using the Repetitive Behavior Questionnaire-2 (RBQ-2). Consistent with previous factor analytic research, 2 factors were found at each age: 1 comprising repetitive…

We examined the prediction that the interaction between Glucocorticoid Receptor Gene ("NR3C1") methylation, stress, and experienced maternal support predicts anxious and avoidant attachment development. This was tested in a general population sample of 487 children and adolescents (44% boys, M[subscript age] = 11.84, SD[subscript age] =…
