The odds ratio (OR) for gender differences in major depression is 1.95, averaged meta-analytically over all ages and nations. The gender difference appears by age 12, OR = 2.37, and peaks at OR = ...3.02 for ages 13-15. Using the ABC (affective, biological, cognitive) model as a framework within a vulnerability-stress approach, we consider the evidence for biological vulnerabilities (genes, pubertal hormones, and pubertal timing), affective vulnerabilities (temperament), and cognitive vulnerabilities (negative cognitive style, objectified body consciousness, and rumination). The impact of stress is central to the vulnerability-stress model, and we review evidence on gender differences in stress exposure, emphasizing gender differences in sex-related traumas such as child sexual abuse and rape. Finally, we examine sociocultural factors that may contribute to the gender difference, including the media and gender inequality. An implication for research methods is that single-gender designs should be questioned. Regarding clinical implications, the vulnerabilities and stressors identified in this review should contribute to personalized interventions with depressed individuals, especially depressed women.
In 2 meta-analyses on gender differences in depression in nationally representative samples, we advance previous work by including studies of depression diagnoses and symptoms to (a) estimate the ...magnitude of the gender difference in depression across a wide array of nations and ages; (b) use a developmental perspective to elucidate patterns of gender differences across the life span; and (c) incorporate additional theory-driven moderators (e.g., gender equity). For major depression diagnoses and depression symptoms, respectively, we meta-analyzed data from 65 and 95 articles and their corresponding national data sets, representing data from 1,716,195 and 1,922,064 people in over 90 different nations. Overall, odds ratio (OR) = 1.95, 95% confidence interval (CI) 1.88, 2.03, and d = 0.27 0.26, 0.29. Age was the strongest predictor of effect size. The gender difference for diagnoses emerged earlier than previously thought, with OR = 2.37 at age 12. For both meta-analyses, the gender difference peaked in adolescence (OR = 3.02 for ages 13-15, and d = 0.47 for age 16) but then declined and remained stable in adulthood. Cross-national analyses indicated that larger gender differences were found in nations with greater gender equity, for major depression, but not depression symptoms. The gender difference in depression represents a health disparity, especially in adolescence, yet the magnitude of the difference indicates that depression in men should not be overlooked.

Using contemporary data from the U.S. and other nations, we address 3 questions: Do gender differences in mathematics performance exist in the general population? Do gender differences exist among ...the mathematically talented? Do females exist who possess profound mathematical talent? In regard to the first question, contemporary data indicate that girls in the U.S. have reached parity with boys in mathematics performance, a pattern that is found in some other nations as well. Focusing on the second question, studies find more males than females scoring above the 95th or 99th percentile, but this gender gap has significantly narrowed over time in the U.S. and is not found among some ethnic groups and in some nations. Furthermore, data from several studies indicate that greater male variability with respect to mathematics is not ubiquitous. Rather, its presence correlates with several measures of gender inequality. Thus, it is largely an artifact of changeable sociocultural factors, not immutable, innate biological differences between the sexes. Responding to the third question, we document the existence of females who possess profound mathematical talent. Finally, we review mounting evidence that both the magnitude of mean math gender differences and the frequency of identification of gifted and profoundly gifted females significantly correlate with sociocultural factors, including measures of gender equality across nations.

Abstract Background We probe the adolescent gender difference in depression, asking two critical questions. First, most longitudinal studies of gender differences in adolescent depression date from ...the 1980 s and 1990 s, raising the need for a body of evidence on whether the developmental pattern is similar or different today. Second, despite the importance of chronicity to depression, we do not know whether there is a gender difference in the chronicity burden of the disorder. Methods In a contemporary longitudinal sample of U.S. adolescents, depression symptoms were assessed at ages 11, 13, 15, and 18, and depression diagnoses were assessed at age 20. To capture the chronicity burden of clinical depression, we assessed for every depressive episode in an individual's lifetime and summed the total number of days spent in episode. Results A gender difference emerged at age 13 for depression symptoms and at age 13-14 for diagnoses. These findings are similar to those in the 1980 s and 1990 s despite many social changes that have occurred. However, the magnitude of the gender difference in symptoms at ages 13 and 15 may be larger than those documented previously. Latent growth curve modeling of depression symptoms indicated that girls’ symptoms accelerated early in adolescence whereas boys’ symptoms accelerated later. Although more girls (24%) than boys (15%) experienced major depression or dysthymia by age 20, the chronicity burden among those with depression showed gender similarities (median = 2.6% days depressed for boys and 2.4% for girls). Limitations Depression diagnoses were assessed retrospectively; however, symptom data were assessed prospectively, and symptom and diagnostic data converged. The sample was also predominantly White, limiting generalizability. Conclusions In a contemporary adolescent sample we observed gender differences in depression symptoms and diagnoses beginning at age 13. We documented distinct developmental trajectories of depression for adolescent girls and boys, suggesting different developmental windows for depression prevention programs. We also discovered a gender similarity in the chronicity burden of clinical depression.

Many college students abandon their goal of completing a degree in science, technology, engineering, or math (STEM) when confronted with challenging introductory-level science courses. In the U.S., ...this trend is more pronounced for underrepresented minority (URM) and first-generation (FG) students, and contributes to persisting racial and social-class achievement gaps in higher education. Previous intervention studies have focused exclusively on race or social class, but have not examined how the 2 may be confounded and interact. This research therefore investigates the independent and interactive effects of race and social class as moderators of an intervention designed to promote performance, measured by grade in the course. In a double-blind randomized experiment conducted over 4 semesters of an introductory biology course (N = 1,040), we tested the effectiveness of a utility-value intervention in which students wrote about the personal relevance of course material. The utility-value intervention was successful in reducing the achievement gap for FG-URM students by 61%: the performance gap for FG-URM students, relative to continuing generation (CG)-Majority students, was large in the control condition, .84 grade points (d = .98), and the treatment effect for FG-URM students was .51 grade points (d = 0.55). The UV intervention helped students from all groups find utility value in the course content, and mediation analyses showed that the process of writing about utility value was particularly powerful for FG-URM students. Results highlight the importance of intersectionality in examining the independent and interactive effects of race and social class when evaluating interventions to close achievement gaps and the mechanisms through which they may operate.

This meta-analysis quantitatively compiled the results of studies from 1992 to 2009 to determine the prevalence and types of victimization experienced by lesbian, gay, and bisexual (LGB) individuals. ...Based on the results of three searches, 386 studies were retrieved and coded. Comparisons were made across all LGB individuals (138 studies), between LGB and heterosexual individuals (65 studies), and between LGB females and males (53 studies), with over 500,000 participants. Multiple types of victimization were coded, including discrimination, physical assault, and school victimization. Findings revealed that for LGB individuals, reports of victimization experiences were substantial (e.g., 55% experienced verbal harassment, and 41% experienced discrimination) and some types have increased since a 1992 review, while others have decreased. LGB individuals experienced greater rates of victimization than heterosexual individuals (range: d = .04-.58). LGB males experienced some types of victimization more than LGB females (e.g., weapon assault and being robbed) but, overall, the gender differences were small. It can be concluded that LGB individuals still experience a substantial amount of victimization. Implications for research methods are discussed, including recommendations for sampling and measurement of victimization.

Antisocial behavior is harmful, financially costly to society, and hard to treat. Callous-unemotional (CU) traits, which predict greater risk for antisocial behavior, are defined in theoretical and ...diagnostic models as representing low empathy, guilt, and prosociality. However, no meta-analytic reviews have systematically integrated the findings of studies that have reported associations between measures of CU traits and empathy, guilt, or prosociality, or potential moderators of these associations, including gender, age, severity of antisocial behavior, and informant (i.e., self or other reports of measures). To address this gap in the literature, we conducted three separate meta-analyses exploring the association between CU traits and empathy, guilt, and prosociality. In follow-up analyses, we explored associations between CU traits and affective versus cognitive empathy. The results revealed statistically significant and moderate-to-large negative associations between measures of CU traits and empathy (ρ = −.57), guilt (ρ = −.40), and prosociality (ρ = −.66). The negative association between CU traits and cognitive empathy was stronger when the informant was a parent or teacher rather than the child, and in younger children. CU traits were also more strongly related to cognitive empathy than affective empathy when the informant was a parent or teacher rather than the child, and in younger children. The findings establish that CU traits are moderately-to-strongly correlated with the presence of callous (low empathy), uncaring (low prosociality), and remorseless (low guilt) behaviors.
•Callous-unemotional (CU) traits predict risk for severe antisocial behavior.•We need better understanding of the core correlates of CU traits.•Higher CU traits were correlated with lower empathy, prosociality, and guilt.•Effect sizes were in the moderate-to-large range across 59 studies.•Effects mostly did not differ based on sex, age, or severity of antisocial behavior.

The pipeline toward careers in science, technology, engineering, and mathematics (STEM) begins to leak in high school, when some students choose not to take advanced mathematics and science courses. ...We conducted a field experiment testing whether a theory-based intervention that was designed to help parents convey the importance of mathematics and science courses to their high school—aged children would lead them to take more mathematics and science courses in high school. The three-part intervention consisted of two brochures mailed to parents and a Web site, all highlighting the usefulness of STEM courses. This relatively simple intervention led students whose parents were in the experimental group to take, on average, nearly one semester more of science and mathematics in the last 2 years of high school, compared with the control group. Parents are an untapped resource for increasing STEM motivation in adolescents, and the results demonstrate that motivational theory can be applied to this important pipeline problem.

On the basis of social structural theory and identity theory, the current study examined changes in gender-role attitudes and behavior across the first-time transition to parenthood and following the ...birth of a second child for experienced mothers and fathers. Data were analyzed from the ongoing longitudinal Wisconsin Study of Families and Work. Gender-role attitudes, work and family identity salience, and division of household labor were measured for 205 first-time and 198 experienced mothers and fathers across 4 time points from 5 months pregnant to 12 months postpartum. Multilevel latent growth curve analysis was used to analyze the data. In general, parents became more traditional in their gender-role attitudes and behavior following the birth of a child, women changed more than men, and first-time parents changed more than experienced parents. Findings suggest that changes in gender-role attitudes and behavior following the birth of a child may be attributed to both the process of transitioning to parenthood for the first time and that of negotiating the demands of having a new baby in the family.
