Children's fears have received scholarly attention for well over 50 years. A considerable amount of literature has focused on such fear variables as fear intensity and fear prevalence scores and age and gender differences. We used meta-analysis to systematically review the findings related to gender differences in children's fear intensity scores…

This meta-analysis reviews 79 studies (N = 46,605) that examined the existence of gender difference on intelligence in school-aged children. To do so, we limited the literature search to works that assessed the construct of intelligence through the Wechsler Intelligence Scales for Children (WISC) batteries, evaluating eventual gender differences…

This study conducted two meta-analyses to synthesize the association between children's language skills and two broad-band dimensions of psychopathology: internalizing and externalizing. Pooled estimates across 139 samples (externalizing k = 105; internalizing k = 90) and 147,305 participants (age range: 2-17 years old; mean % males: 53.75; mean %…

The aim of this study is to examine the effect size of depression in a Turkish sample with respect to gender and developmental periods. The studies of dissertation and articles completed during the period of 2004-2018 and covering Turkish sample have been examined through the method of Meta Analysis. The studies carried out, with the help of the…

Being overweight or obese (overweight/obesity) or physically aggressive in childhood and adolescence can have lifelong consequences, hence are important public health problems. Identifying a relationship between these problems would assist in understanding their developmental origins. The present paper sought to review previous studies and use…

Background: Numerous studies have looked at the efficacy of Parent-Child Interaction Therapy (PCIT) for young children with externalizing behaviour problems. Objective: The present study compiled these results through a comprehensive review to provide greater clarity regarding the efficacy of this treatment. Methods: Using a random effects model,…

Child gender has been proved to affect toddlers'/children's language development in several studies, but its effect was not found to be stable across different ages or various aspects of language ability. The effect of gender on toddler's, children's and adolescents' language ability was examined in the present meta-analysis of ten Slovenian…

Research on the effects of physical activity on children with attention deficit hyperactivity disorder is promising, yet no attempt has been made to integrate current findings using meta-analytic techniques. Using a meta-regression, the present study examined the effectives of physical activity for children with attention deficit hyperactivity…

A cross-sectional case-control study was carried out to evaluate the concentrations of metallic elements in the hair of 44 children with diagnosis of autism and 61 age-balanced controls. Unadjusted comparisons showed higher concentrations of molybdenum, lithium and selenium in autistic children. Logistic regression analysis confirmed the role of…

It has been argued that children who possess an advanced theory of mind (ToM) are more likely to act prosocially, yet the empirical findings are mixed. To address this issue definitively, a meta-analytic integration of all prior literature that met appropriate inclusion criteria was conducted. In total, 76 studies including 6,432 children between…

Autism is an extensively studied disorder in which the gender disparity in prevalence has received much attention. In contrast, only a few studies examine gender differences in symptomatology. This systematic review and meta-analysis of 22 peer reviewed original publications examines gender differences in the core triad of impairments in autism.…

There are several theoretical reasons to believe that media use might be related to attention-deficit/hyperactivity disorder (ADHD) or ADHD-related behaviors (i.e., attention problems, hyperactivity, and impulsivity). Although studies into the media--ADHD relationship have accumulated, they have yielded inconsistent results. Therefore, we still do…

Objective: Gender differences among children with ADHD are not well understood. The continuous performance test (CPT) is the most frequently used direct measure of inattention and impulsivity. This meta-analysis compared CPT performance between boys and girls with and without ADHD. Method: All peer-reviewed ADHD studies published between 1980 and…

Youth aggression has been associated with negative parenting practices, but previous research about this association has mainly focused on physical and verbal aggression. Because more subtle forms of aggression are considered at least as harmful as their physical and verbal counterparts, there is a growing scientific interest in parenting…

Background: Prospective evidence on psychological outcomes for children with specific language impairments (SLI) is accumulating. To date, there has been no attempt to summarise what this evidence says about the strength of link between SLI and later child and adolescent emotional and behavioural (EB) outcomes. Methods: We undertook a systematic…
