The Links Between Parent Behaviors and Boys' and Girls' Science Achievement Beliefs

This study examined whether parental involvement in children's science schoolwork (i.e., discussions about science, homework helping and encouragement of science interest) varies for boys and girls, and how these behaviors relate to children's science achievement beliefs (i.e., ability perceptions and task-value) at the end of a school year. We analyzed these links both for fathers and mothers and examined whether child gender moderates how parental behaviors relate to children's beliefs over time. Data were gathered over a span of a school year from 114 middle-school students (50% girls, 81% European American) and their parents (mothers: n = 103, fathers: n = 90). We found support for the moderating effect of gender. Specifically, the findings indicated that only parents' encouragement of science interest varied by child gender; mothers' encouragement positively predicted girls' self-assessments of science ability at the end of the year, but was a negative estimator of boys' self-assessments. Additionally, mothers' discussions about science showed similar findings with respect to girls' and boys' utility beliefs about science.     

Fathers' and Mothers' Home Literacy Involvement and Children's Cognitive and Social Emotional Development: Implications for Family Literacy Programs

The relations between fathers' and mothers' home literacy involvement at 24 months and children's cognitive and social emotional development in preschool were examined using a large sample of African American and Caucasian families (N = 5190) from the Early Childhood Longitudinal Study-Birth Cohort (ECLS-B). Hierarchical regression analyses revealed that both fathers' and mothers' home literacy involvement positively contributed to children's cognitive and social emotional development. Specifically, fathers and mothers who participated in more frequent home literacy involvement (e.g., shared book reading) had children with better reading, math, and social emotional outcomes (i.e., sustained attention and fewer negative behaviors) in preschool. Findings suggest that increasing family literacy involvement can have positive benefits for children's cognitive and social emotional skills during the developmentally important early childhood years.     

Sibling and environment correlates of children's achievement: Sex group differences

Abstract

Regression surface analysis was used to examine associations between sibling variables and measures of academic achievement and intellectual ability at different levels of social status and family environment variables for girls and boys. The sample was 460 Anglo‐Australian families, each with an 11‐year‐old child. Family environments were defined by parents’ aspirations for their children and parents’ instrumental and affective orientations. Regression models included terms to account for possible linear, interaction, and curvilinear relations between sib size and birth order and measures of word knowledge, word comprehension, mathematics performance, and intellectual ability. The findings indicated that the sibling variables were poor predictors of children's cognitive performance. Typically, sib size and birth order were not related to children's academic performance at different levels of family environment scores.     

A Latent Class Analysis of Bullies,Victims and Aggressive Victims in Chinese Adolescence: Relations with Social and School Adjustments

This study used the latent class analysis (LCA) to identify and classify Chinese adolescent children''s aggressive behaviors. It was found that (1) Adolescent children could be divided into four categories: general children, aggressive children, victimized children and aggressive victimized children. (2) There were significant gender differences among the aggressive victimized children, the aggressive children and the general children. Specifically, aggressive victimized children and aggressive children had greater probabilities of being boys; victimized children had equal probabilities of being boys or girls. (3) Significant differences in loneliness, depression, anxiety and academic achievement existed among the aggressive victims, the aggressor, the victims and the general children, in which the aggressive victims scored the worst in all questionaires. (4) As protective factors, peer and teacher supports had important influences on children''s aggressive and victimized behaviors. Relative to general children, aggressive victims, aggressive children and victimized children had lower probabilities of receiving peer supports. On the other hand, compared to general children, aggressive victims had lower probabilities of receiving teacher supports; while significant differences in the probability of receiving teacher supports did not exist between aggressive children and victimized children.     

Influence of parents' eating behaviors and child feeding practices on children's weight status

Objective : To investigate the effects of mothers’ and fathers’ eating behaviors, child feeding practices, and BMI on percentage body fat and BMI in their children. Research Methods and Procedures : Four hundred fifty‐eight parents (239 mothers, 219 fathers) were asked to complete two questionnaires: the Three‐Factor Eating Questionnaire and the Child Feeding Questionnaire, which measure dimensions of parent eating behavior and child feeding practices, respectively. Parent BMI was calculated from self‐reported height and weight; children's measures included BMI and percentage fat assessed by DXA. Regression analyses were used to analyze relationships between parents’ BMI and questionnaire scores and children's weight status. Results : One hundred forty‐three mothers and 68 fathers returned questionnaires, representing parents of 148 children 3 to 5 years old (78 boys). Children's weight was related to mothers’ BMI, but not fathers’. Girls had a greater BMI if either parent reported being overweight as a child, and both girls and boys were likely to be overweight if their mothers believed they had risky eating habits (fussiness, eating too much, etc.). Girls with fathers who were more controlling had a higher percentage fat; these fathers were also more concerned about their daughters’ future health. Discussion : Mothers exert a strong influence over their children's weight and seem to be more concerned about their children's eating behaviors; however, fathers play a role in imposing child feeding practices. Gender bias may be present in child feeding, as suggested by dissimilar effects of parent practices on the weight status of girls vs. boys. Fathers should be included in future studies analyzing parent feeding practices and children's weight outcome.     

Mapping Temporal Dynamics in Social Interactions With Unified Structural Equation Modeling: A Description and Demonstration Revealing Time-Dependent Sex Differences in Play Behavior

Developmental science is rich with observations of social interactions, but few available methodological and statistical approaches take full advantage of the information provided by these data. The authors propose implementation of the unified structural equation model (uSEM), a network analysis technique, for observational data coded repeatedly across time; uSEM captures the temporal dynamics underlying changes in behavior at the individual level by revealing the ways in which a single person influences—concurrently and in the future—other people. To demonstrate the utility of uSEM, the authors applied it to ratings of positive affect and vigor of activity during children's unstructured laboratory play with unfamiliar, same-sex peers. Results revealed the time-dependent nature of sex differences in play behavior. For girls more than boys, positive affect was dependent upon peers' prior positive affect. For boys more than girls, vigor of activity was dependent upon peers' current vigor of activity.

The Influence of Parenting Change on Pediatric Weight Control

Objective: Parenting style was examined as a predictor of weight loss maintenance in behavioral family‐based pediatric obesity treatment. Research Methods and Procedures: Fifty obese children who participated in a behavioral family‐based pediatric obesity treatment were studied. Hierarchical regression tested the incremental effect of baseline parenting and parenting during treatment on children's percentage overweight change over 12 months, beyond demographics and adherence to targeted behaviors. Results: Children's percentage overweight significantly decreased at 6 (?16.3) and 12 (?11.1) months. Adherence to program goals significantly increased variance accounted for in the regression model by 10.8%, whereas adding baseline father acceptance and change in father acceptance accounted for another 20.5%. The overall model accounted for 40.6% of the variance in pediatric weight control. ANOVA showed significantly greater percentage overweight decrease from baseline for youth with fathers who increased their acceptance vs. those who decreased acceptance at 6 (?19.8 vs. ?14.6) and 12 (?17.4 vs. ?8.1) months. Discussion: Youth who perceive an increase in father acceptance after treatment had better changes in percentage overweight over 12 months than youth with lower ratings of father acceptance. Future directions include examining how other parenting dimensions impact pediatric obesity treatment outcome and how parental acceptance can be enhanced to improve child weight control.     

The Educational Benefits of a Ten-Week Home-Based Wild Bird Feeding Program for Children

ABSTRACT

This study evaluated a ten-week educational home-based program for feeding wild birds, intended to increase elementary school age children's knowledge about birds, especially those wild birds commonly encountered at outdoor home feeders. We measured changes from pre- to post-program in 65 seven- to 12-year old children's knowledge about wild birds, as well as in environmental attitudes. The goal was not only to increase bird knowledge in the target child but also to involve other family members in home-based nature education activities. After the program, seven- to nine-year old boys and girls showed significant gains in bird knowledge, but older children (10–12 years) did not significantly improve. Children's increased knowledge was positively associated with parental education. There was no systematic change in environmental attitudes. Parents identified family involvement as a particularly beneficial aspect of the program, and 90% of contacted families were still feeding birds one year after program termination.     

Intergenerational Perceptions of Body Image in Hispanics: Role of BMI,Gender, and Acculturation

Objective: To assess role of BMI, gender, and acculturation on maternal and children's perception of body size, body ideal, and attractiveness. Research Methods and Procedures: Eighty mothers and their 6‐ to‐ 12‐year‐old children (41 boys, 39 girls) participated. Maternal and children's perceptions of body size (actual and ideal) and attractiveness were assessed through a pictorial instrument. Mother and child height and weight, demographic, and acculturation characteristics were also assessed. Results: Seventy‐nine percent of the mothers were overweight, and 32% of the boys and 34% of the girls were overweight or at‐risk for overweight. BMI influenced the children's selection of perceived ideal size. Overweight or at‐risk for overweight children were more likely to select thinner figures as the ideal size than non‐overweight children. Gender and acculturation differences concerning children's perceptions of body size and attractiveness were also found. Girls perceived the obese figure as being less attractive than did the boys. More acculturated children were likely to select thinner figures as more attractive than their less acculturated counterparts. Maternal acculturation was associated positively with the girls’ choice of thinner figures as an ideal body size, but not with the boys. Mothers viewed their daughters’ actual body size and BMI as ideal, although 34% of the girls were at‐risk for overweight. Mothers perceived average body size figures as more attractive for their sons. Discussion: Findings from this study provide empirical data about the role of BMI, gender, acculturation, and familial influences on children's perceptions of actual and ideal body sizes and attractiveness.     

Bone Mineral Density of the Spine in 11,898 Chinese Infants and Young Children: A Cross-Sectional Study

Background

Bone mineral density (BMD) increases progressively during childhood and adolescence and is affected by various genetic and environmental factors. The aim of this study was to establish reference values for lumbar BMD in healthy Chinese infants and young children and investigate its influencing factors.

Methods and Findings

Healthy children aged 0 to 3 years who underwent regular physical examinations at the Child Health Care Clinic of Hubei Maternal and Child Health Hospital (N = 11,898) were recruited for this study. We also chose 379 preterm infants aged 0 to 1 years to preliminarily explore the development of BMD in this special population. BMD (g/cm²) measurements of the lumbar spine (L2–L4) were carried out with dual-energy X-ray absorptiometry and a questionnaire was administered to full-term children''s parents to gather information on various nutritional and lifestyle factors as well as mothers'' nutritional supplement use during pregnancy. Lumbar BMD significantly increased with age among both boys and girls (p<0.05), with fastest growth observed during the first postnatal year. There was no significant difference in lumbar BMD between boys and girls of similar age (p>0.05), either among healthy reference children or preterm infants. However, BMD values in preterm infants were significantly lower than those in term infants 3 to 8 months old (p<0.05) after adjustment for gestational age. Multivariable linear regression analysis indicated significant positive associations between lumbar BMD of healthy children and the child''s age and current weight, mother''s weight gain during pregnancy, birth weight, children''s outdoor activity duration and children''s physical activity duration.

Conclusion

Our study provides reference values of lumbar BMD for healthy Chinese children aged 0 to 3 years and identifies several influencing factors.     

Population-Level Associations between Preschool Vulnerability and Grade-Four Basic Skills

Background

This is a predictive validity study examining the extent to which developmental vulnerability at kindergarten entry (as measured by the Early Development Instrument, EDI) is associated with children''s basic skills in 4th grade (as measured by the Foundation Skills Assessment, FSA).

Methodology/Principal Findings

Relative risk analysis was performed on a large database linking individual-level EDI ratings to the scores the same children obtained on a provincial assessment of academic skills (FSA – Foundation Skills Assessment) four years later. We found that early vulnerability in kindergarten is associated with the basic skills that underlie populations of children''s academic achievement in reading, writing and math, indicating that the Early Development Instrument permits to predict achievement-related skills four years in advance.

Conclusions/Significance

The EDI can be used to predict children''s educational trends at the population level and can help select early prevention and intervention programs targeting pre-school populations at minimum cost.     

The Relationship between the Second-to-Fourth Digit Ratio and Behavioral Sexual Dimorphism in School-Aged Children

Sexually dimorphic brain development and behavior are known to be influenced by sex hormones exposure in prenatal periods. On the other hand, second-to forth digit ratio (2D/4D) has been used as an indirect method to investigate the putative effects of prenatal exposure to androgen. In the present study, we herein investigated the relationship between gender-role play behavior and the second-to-fourth digit ratio (2D/4D), which has been used as an indirect method to investigate the putative effects of prenatal exposure to androgens, in school-aged children. Among 4981 children who became 8 years old by November 2014 and were contactable for this survey by The Hokkaido Study of Environment and Children''s Health, 1631 (32.7%), who had data for 2D/4D and Pre-school Activities Inventory (PSAI) as well as data for the survey at baseline, were available for analysis. Parents sent reports of PSAI on the sex-typical characteristics, preferred toys, and play activities of children, and black and white photocopies of the left and right hand palms via mail. PSAI consisted of 12 masculine items and 12 feminine items, and a composite score was created by subtracting the feminine score from the masculine score, with higher scores representing masculine-typical behavior. While composite scores in PSAI were significantly higher in boys than in girls, 2D/4D was significantly lower in boys than in girls. Although the presence or absence of brothers or sisters affected the composite, masculine, and feminine scored of PSAI, a multivariate regression model revealed that 2D/4D negatively correlated with the composite scores of PSAI in boys, whereas no correlation was found in girls. Although 2D/4D negatively correlated with the masculine score in boys and girls, no correlation was observed between 2D/4D and the feminine score. In conclusion, although social factors, such as the existence of brother or sisters, affect dimorphic brain development and behavior in childhood, the present study revealed that the prenatal hormonal environment was an important factor influencing masculine-typical dimorphic brain development and behavior in school-aged children.     

Development, problem behavior, and quality of life in a population based sample of eight-year-old children with Down syndrome

Objective

Children with Down syndrome (DS) have delayed psychomotor development. We investigated levels of development, problem behavior, and Health-Related Quality of Life (HRQoL) in a population sample of Dutch eight-year-old children with DS. Developmental outcomes were compared with normative data of eight-year-old children from the general population.

Method

Over a three-year-period all parents with an eight-year-old child with DS were approached by the national parent organization. Developmental skills were assessed by means of the McCarthy Scales of Children''s Ability. To measure emotional and behavioral problems we used the Child Behavior Checklist. HRQoL was assessed with the TNO-AZL Children''s Quality of Life questionnaire. Analyses of variance were applied to compare groups.

Results

A total of 337 children participated. Mean developmental age was substantially lower than mean calendar age (3.9 years, SD 0.87 and 8.1 years, SD 0.15 respectively). Mean developmental age was significantly lower among boys than girls (3.6 (SD 0.85) and 4.2 years (SD 0.82) respectively; p<0.001). Compared with the general population, children with DS had more emotional and behavioral problems (p<0.001). However on the anxious/depressed scale, they scored significantly more favorably (p<0.001). Significantly lower HRQoL scores for the scales gross motor skills, autonomy, social functioning and cognitive functioning were found (p-values<0.001). Hardly any differences were observed for the scales physical complaints, positive and negative emotions.

Conclusion

Eight-year-old children with DS have an average developmental delay of four years, more often have emotional and behavioral problems, and have a less favorable HRQoL compared with children from the general population.     

Blood Lead Levels and Associated Factors among Children in Guiyu of China: A Population-Based Study

Objectives

Children''s health problems caused by the electronic waste (e-waste) lead exposure in China remains. To assess children''s blood lead levels (BLLs) in Guiyu of China and investigate risk factors of children''s elevated BLLs in Guiyu.

Material and Methods

842 children under 11 years of age from Guiyu and Haojiang were enrolled in this population-based study during 2011–2013. Participants completed a lifestyle and residential environment questionnaire and their physical growth indices were measured, and blood samples taken. Blood samples were tested to assess BLLs. Children''s BLLs between the two groups were compared and factors associated with elevated BLLs among Guiyu children were analyzed by group Lasso logistic regression model.

Results

Children living in Guiyu had significant higher BLLs (7.06 µg/dL) than the quantity (5.89 µg/dL) of Haojiang children (P<0.05). Subgroup analyses of BLLs exceeding 10 µg/dL showed the proportion (24.80%) of high-level BLLs for Guiyu children was greater than that (12.84%) in Haojiang (P<0.05). Boys had greater BLLs than girls, irrespectively of areas (P<0.05). The number of e-waste piles or recycling workshops around the house (odds ratio, 2.28; 95% confidence interval [CI], 1.37 to 3.87) significantly contributed to the elevated BLLs of children in Guiyu, and girls had less risk (odds ratio, 0.51; 95% CI, 0.31 to 0.83) of e-waste lead exposure than boys.

Conclusions

This analysis reinforces the importance of shifting e-waste recycling piles or workshops to non-populated areas as part of a comprehensive response to e-waste lead exposure control in Guiyu. To correct the problem of lead poisoning in children in Guiyu should be a long-term mission.     

The Children's Treatment of Animals Questionnaire: A Rasch Analysis

ABSTRACT

The study of human–animal interactions is limited by a paucity of empirically validated measures of humane treatment of companion animals. The current study reports findings from a psychometric analysis of the Children's treatment of animals Questionnaire (CTAQ; thompson and Gullone 2003), an instrument that assesses children's humane interactions with nonhuman animals. Specifically, the current study extends what is known about the psychometric properties of the CTAQ by using traditional and item response theory analyses. The CTAQ was administered to a sample of 217 school-age children whose mothers were currently receiving residential or non-residential domestic violence services. Item-analysis, exploratory factor analysis, and parallel analysis were conducted to replicate previous psychometric evaluations of the CTAQ. Rasch analysis of the CTAQ was also conducted to provide a stringent test of unidimensionality and to identify potential invariance in item functioning across various demographic variables. The CTAQ showed adequate fit to the Rasch model; one modification, removal of item 5, was required. A Rasch principal components analysis of residuals indicated a single latent dimension among the remaining 12 items. Scale use was appropriate; Rasch-andrich thresholds increased with category values and no disordering of categories was evident. Examination of item-person maps indicated the sample was also well-targeted. Notably, evidence of differential item function was found across Spanish and English translations. Overall, findings indicate that the CTAQ is an appropriate unidimensional measure of children's humane treatment of animals. The measure is particularly well-suited for children ages 7 to 12 years who are at risk for exposure to and perpetration of animal cruelty. We recommend use of a 12-item version of the CTAQ to enhance the utility of the total score as a latent measure of children's humane treatment of companion animals.     

Consultation for Teachers and Children's Language and Literacy Development during Pre-Kindergarten

MyTeachingPartner (MTP) is a teacher professional development program designed to improve the quality of teacher-child interactions in pre-kindergarten classrooms and children's language and literacy development. The program includes language/literacy activities and two Web-based resources—video exemplars of effective interactions and individualized consultation—designed to support teachers' high quality implementation of these activities. This study examined the impacts of the MTP Web-based resources on the language and literacy development of 1,165 children during pre-kindergarten. Children whose teachers were randomly assigned to receive access to both the video exemplars and participated in consultation (MTP Consultancy n = 65) made greater gains in receptive language skills during pre-kindergarten compared to children whose teachers were randomly assigned to receive access to the video exemplars only (MTP Video Library n = 69). Further, among MTP Consultancy teachers, more hours of participating in the consultation process was positively associated with children's receptive language development, and more hours implementing the language/literacy activities was positively associated with children's language and literacy development. Implications for improving children's school readiness and promoting teachers' participation in professional development programs are discussed.     

Parents' Socializing Behavior and Children's Participation in Math,Science, and Computer Out-of-School Activities

This study examined associations between multiple parental behaviors and children's participation in out-of-school math, science, and computer activities for children in 2nd (n = 125), 3rd (n = 123), and 5th grade (n = 200). Mothers and fathers reported how often they encouraged their children's activities, participated in activities with their child, provided activity-related materials, and participated in activities themselves, as well as how often their children participated in activities. The youth described how often they participated in math, science, and computer activities. Results indicate that parents' behavior is a strong, positive predictor of children's participation. Although there were significant mean level gender differences, relations between parents' behavior and children's participation were similar for boys and girls.     

Classroom Race/Ethnic Composition,Family-School Connections,and the Transition to School

Using data from the Early Childhood Longitudinal Study–Kindergarten Cohort (N = 13,970), we examined whether two aspects of school-family connections, parental involvement and communication quality, accounted for the association between classroom composition and children's academic and socioemotional functioning following the transition to elementary school. For students with more same-race/ethnic representation in their classrooms, greater classroom race/ethnic diversity promoted more parental involvement, which in turn promoted children's interpersonal skills and reading achievement. Classroom diversity made little difference to parental involvement when students had fewer same-race/ethnic peers in the classroom. Teacher–parent communication quality did not emerge as an explanatory mechanism, and findings did not vary by the race/ethnic match between students and their teachers.     

The influence of immigrant parent legal status on U.S.-born children's academic abilities: The moderating effects of social service use

The present study investigated the relationship between immigrant parent legal status and academic performance among U.S.-born children, ages 7–10. Building on previous research and a social ecological framework, the study further explored how social service use moderates the relationship between parent legal status and academic performance. Participants included 178 low-income, urban parent/child dyads; all parents were immigrants from Mexico, Central America, or the Dominican Republic and all children were U.S.-born citizens. Using a standardized academic assessment as the outcome, parent legal vulnerability was a significant negative predictor of children's academic performance on reading, spelling, and math subtests. Additionally, parent use of social services significantly and positively moderated the relationship between parent legal vulnerability and children's word reading and spelling skills, indicating that social service use can serve as a protective buffer against the negative associations between parental unauthorized status and child achievement.
