Sex differences in symptoms of depression among American children and adolescents

The Arabic Children's Depression Inventory in its English version was administered to a sample of 535 U.S. school students (11 to 18 years old). By sex, differences on total score and on 19 of 27 items (70.4%) were not statistically significant. Nevertheless, differences were significant for 8 (29.6%) items on which girls had higher mean scores. Half of the items were positive indicators of depression (I am sad, I feel lonely, I feel miserable, and I hate myself), while the other half were negative (I feel happy, Life is rosy, A lot of people like me, and I am optimistic).     

Relationship between impulsiveness and deviant behavior among adolescents in the classroom: age and sex differences

To assess the relationship between impulsiveness and deviant behavior among 103 adolescents, taking into account their sociodemographic characteristics, the Barratt Impulsiveness Scale and a self-assessment measure with regard to disruptive and deviant behaviors which had occurred in the last 90 days were used. The results show that impulsiveness and disruptive behavior in the classroom were related to deviant behavior outside of the classroom. Therefore, age and sex explained the relationship between impulsiveness and behavior. The older adolescents and the girls showed less disruptive behaviors than the younger participants and the boys; both variables showed an interactive effect on disruptive behavior. The age at which sexual activity commenced and the number of sexual partners were also significantly related to impulsiveness and disruptive and deviant behavior. Similarly, impulsiveness was shown to have a significant relationship with disruptive and deviant behavior, and disruptive behavior was shown to have a significant relationship with deviant behavior.     

The Japanese State-Trait Anxiety Inventory: age and sex differences

Purpose of the present study was to investigate scores on anxiety among adults of different ages. The State-Trait Anxiety Inventory was administered to a representative community sample of 1,234 men and women whose ages ranged from 25 to 92 yr. Anxiety declined linearly over the series of age groups. A sex difference was also observed on trait anxiety; women showed higher anxiety than men. Occupation was associated with anxiety for men but with education for women. Possible development of anxiety and differential association of demographic variables with anxiety between sexes were discussed in relation to personality.     

Preliminary examination of sex differences in depressive symptoms among adolescent psychiatric inpatients: the role of anxious symptoms and generalized negative affect.

Assessed the emerging view that generalized negative affect and anxious symptoms are important in understanding sex differences in depressive symptoms. Sixty-three adolescent psychiatric inpatients (32 boys, 31 girls), ages 12 to 16 (M = 13.87, SD = 1.36), completed measures of positive and negative affect and anxious and depressive symptoms. Results demonstrated, as predicted, that depressive and anxious symptoms were more highly associated in adolescent girls than boys. Furthermore, girls with depressive symptoms were more likely to have comorbid anxious symptoms than boys with depressive symptoms. Sex differences were not found for adolescents with specific depressive symptoms and specific anxious symptoms (i.e., the absence of comorbidity). Our findings supported the possibility that sex differences in pure forms of depression are overestimated and that comorbid internalizing conditions may be more prevalent in adolescent girls than boys.     

Preschoolers' beliefs about sex and age differences in emotionality

The goal of the present study was to assess preschoolers' beliefs about the frequency and intensity with which boys, girls, women, and men experience anger, sadness, and happiness. Sixty-seven middle-class preschool children (35 girls, 32 boys) were presented with drawings of adult and child figures of each sex, and were asked to rate how frequently and intensely the emotions were felt (91% of the children were white; the remainder were primarily black). Children's gender stereotyped beliefs were particularly strong for sadness and appeared to be based on a deficit-experience model for males. Sex of target differences also were found for children's beliefs about anger (favoring males). However, the sex difference in anger was based more on the degree to which anger is believed to be experienced rather than on differences in beliefs regarding males' and females' capacity to experience anger. Age of target differences were also found for sadness and anger, but not for happiness. It was concluded that preschoolers' beliefs about differences in emotions are complex, and vary as a function of the sex and age of the target person, and as a function of the specific emotion.Partial support for Richard Fabes was provided by a grant from the National Science Foundation (BNS-8807784).

Explaining age and sex differences in children's handwriting: A neurobiological approach

The present study aimed to assess the effect of age and sex on children's writing performance, as well as to investigate possible age and sex differences between proficient, intermediate and poor writers. Two hundred and ten children aged 7 to 12 years were examined during spontaneous writing, copying and writing to dictation, using the writing scale of the Luria – Nebraska neuropsychological battery. Results showed a significant effect of age in writing performance. The trend towards writing proficiency in childhood was found to be sex related, while boys were overrepresented among the poor writers. The findings are interpreted on the basis of the neurobiological theories of brain development as well as on the different rates of cerebral maturation between the sexes.     

Happiness among adolescents in The Netherlands: ethnic and sex differences

A nationwide sample of 2710 Dutch adolescents and 518 ethnic minority adolescents living in the Netherlands was used to examine ethnic and sex differences in happiness. Analyses of variance were conducted with ethnic background, sex, and length of residence in the Netherlands, as variables. Socioeconomic status was included in the analyses as a covariate. Adolescents from ethnic minority backgrounds, as compared to the Dutch, had significantly lower scores on a generalized estimates of life satisfaction and on a measure of hedonic effect. Both differences, however, explained only a very small amount of variance. Girls (from all ethnic groups including the Dutch) had lower scores than boys on both measures. There was no significant effect for length of residence on either measure.     

Stress and coping among gay men: age and ethnic differences

Previous studies suggest that perceived stigmatization of sexual minority status, ethnicity, and age are associated with negative mental health outcomes, and other studies suggest that coping styles may influence these outcomes. However, no studies have examined these relationships among gay men of varying ethnicities and age groups. Three hundred eighty-three Black and White, younger, middle-aged, and older adult gay men completed measures of perceived stigmatization, coping style, and mental health outcomes. Black older adult gay men reported significantly higher levels of perceived ageism than the older White group, significantly higher levels of perceived racism than the younger Black group, significantly higher levels of homonegativity than the younger Black and the White groups, and were more likely to use disengaged coping styles than White gay men. However, Black older adult gay men did not experience significantly higher levels of negative mental health outcomes. Results suggest that further research should examine how older Black gay men, who perceive higher levels of stigma while reporting greater use of less effective coping styles, do not appear to be experiencing more negative mental health outcomes as a result.     

Morningness-eveningness and sleep habits among adolescents: age and gender differences

Previous research has indicated the need to use large samples in different cultural contexts in order to clarify age and gender differences on morningness-eveningness and sleep habits. The goal of our research was to study the relationship between morningness-eveningness and sleep habits in a large sample of 2,649 adolescents between 12 and 16 years. The Morningness- Eveningness Scale for Children and an adaptation of the School Sleep Habits Survey measures were used. Results indicated a greater tendency toward eveningness with age and higher eveningness in 13- and 14-year-old girls. Older adolescents claimed later rising time on weekends, later bedtime and shorter sleep length, and greater social jetlag, weekend rise time delay, and weekend bedtime delay. Girls reported earlier rising time on weekdays, later rising time on weekends, longer sleep length on weekends, and greater social jetlag and weekend rising time delay. Lastly, evening oriented adolescents claimed later rising time and bedtime, shorter sleep length on weekdays but longer sleep duration on weekends, and greater social jetlag, weekend rising time delay, and weekend bedtime delay.     

Problem-solving deficits and depressive symptoms among children

Depressive symptoms among 40 fourth- and fifth-grade students as measured by the Children's Depression Inventory, correlated highly with impaired problem solving at block designs (r = .64) and anagrams (r = .67). Similar impairments have been found among depressed adults, suggesting that depression among children may be continuous with depression among adults.     

Cognitive gender differences among Israeli children

The study investigated gender differences among 11,000 Israeli children in Grades 4–6 with respect to verbal, spatial, and mathematical ability, as measured by 12 intelligence tests. Consistent differences in score variance were found across grades for 11 of the 12 tests. In each of these tests the variance for boys exceeded that for girls by 10%–20%. With respect to mean achievement, consistent cross-grade differences were found only for mathematical ability, where boys had the edge (about 0.20 SD). These findings diverge from those of recent American studies, which found no gender differences in any of these realms. Furthermore, they differ from the results of earlier Israeli studies in that the gender gap is limited to mathematical ability, and its size is much smaller. The revealed gender gap can be partially attributed to differences in response strategy: girls were found to be more likely to skip items for which they lack an answer (i.e., to take fewer risks in guessing). This implies that the performance of girls on intelligence tests will improve if they are encouraged to dare to guess.This research was supported by the Henrietta Szold Research Institute.

Social comparisons by children: An analysis of research on sex differences

This article analyzes research on social comparisons by children of elementary school age or younger with respect to sex differences. First, theoretical perspectives are briefly examined, which yield a conceptual framework for the study of social comparison. Then, relevant research is reviewed. This research has been categorized according to whether children were investigated in laboratory-controlled or naturalistic settings. Next, a summary is delineated for the reader, highlighting major findings and emphasizing points of similarity and contrast between studies. Finally, recommendations are drawn for future research.     

Population sex differences in IQ at age 11: the Scottish mental survey 1932

There is uncertainty whether the sexes differ with respect to their mean levels and variabilities in mental ability test scores. Here we describe the cognitive ability distribution in 80,000+ children—almost everyone born in Scotland in 1921—tested at age 11 in 1932. There were no significant mean differences in cognitive test scores between boys and girls, but there was a highly significant difference in their standard deviations (P<.001). Boys were over-represented at the low and high extremes of cognitive ability. These findings, the first to be presented from a whole population, might in part explain such cognitive outcomes as the slight excess of men achieving first class university degrees, and the excess of males with learning difficulties.     

Parent-child physical play: The effects of sex and age of children and parents

Physical play is an important vehicle for differential socialization of boys and girls into appropriate sex roles. The aim of the study was to examine developmental changes in patterns of parent-child physical play as a function of the sex of parent and child. Three hundred ninety families with a total of 746 children ranging in age from under 1 year to 10 years were contacted by telephone and questioned about the frequency of physical-play interactions with their children. The results indicated that the strongest variable affecting the frequency of physical play was the age of the child. This developmental effect was curvilinear, with comparatively low levels prior to age one, a peak in the early childhood years, and the decline thereafter. Fathers tended to engage in more physical play than mothers. Effects of child sex were less evident, but tended to indicate that girls participated more often in nonstrenuous physical games with their parents, such as pattycake and being bounced on the parent's knee, while boys participated more often in activities such as wrestling and ball playing. There was a modest but significant tendency for older parents to engage less often in physical play with their children at each age level. The implications of parent-child physical play for sex role typing were noted.     

Gender and age differences in spiritual development among early adolescents

ABSTRACT

The current study examined age and gender effects on spiritual development among early adolescents. A total sample of 416 Czech adolescents, age ranged from 11 to 15 years, was analysed for the study. Data was collected employing a non-experimental survey design by utilizing a self-administered questionnaire. A series of independent t-tests were performed to determine whether there were significant age and gender differences across the spirituality indicators: spiritual well-being, spiritual belief, and experiential spirituality. Results indicated that 11-year-old adolescents were more likely to demonstrate a higher level of spiritual well-being and spiritual belief compared with those 15-year-old; while 15-year-old adolescents were more likely to score high in experiential spirituality than their younger counterparts. Regarding gender, girls were more likely than boys to demonstrate a higher level of spirituality score. Practitioners in education and psychology should be mindful of the use of spirituality interventions applying the respective forms and practices according to age and gender to better promote positive youth development.     

Gender differences in emotional support and depressive symptoms among adolescents: A prospective analysis

Investigated components of perceived emotional support, including support from family members, nonfamily adults, and peers, as predictors of depressive symptoms in a sample of 333 high school students (age 14-18) using a prospective design. Analyses of panel questionnaire data at two points in time suggest there are significant gender differences both in the quality of perceived support reported by adolescents and in the importance of support variables as predictors of depressive symptoms. Although there are no gender differences in the magnitude of perceived support from family members, girls report higher emotional support from both nonfamily adults and peers than boys report. Simple correlations between family support and depression are significantly stronger for girls than for boys. Results of hierarchical regression analyses, controlling for initial level of symptoms, reveal that whereas both nonfamily adult and friend components of perceived support are significant predictors of changes in symptoms for girls, none of these variables significantly predicts changes in symptoms for boys in this sample. In addition, initial symptoms predict changes in family support for girls but not for boys.
