Gender Similarities Characterize Math Performance

Gender differences in mathematics performance and ability remain a concern as scientists seek to address the underrepresentation of women at the highest levels of mathematics, the physical sciences, and engineering. Stereotypes that girls and women lack mathematical ability persist and are widely held by parents and teachers. Meta-analytic findings from 1990 (6) indicated that gender differences in mathematics performance in the general population were trivial, d = -.05. d = Mmales – Mfemales sw

New trends in gender and mathematics performance: A meta-analysis.

In this article, we use meta-analysis to analyze gender differences in recent studies of mathematics performance. First, we meta-analyzed data from 242 studies published between 1990 and 2007, representing the testing of 1,286,350 people. Overall, d = 0.05, indicating no gender difference, and variance ratio = 1.08, indicating nearly equal male and female variances. Second, we analyzed data from large data sets based on probability sampling of U.S. adolescents over the past 20 years: the National Longitudinal Surveys of Youth, the National Education Longitudinal Study of 1988, the Longitudinal Study of American Youth, and the National Assessment of Educational Progress. Effect sizes for the gender difference ranged between -0.15 and +0.22. Variance ratios ranged from 0.88 to 1.34. Taken together, these findings support the view that males and females perform similarly in mathematics.

A Measure of Objectified Body Consciousness for Preadolescent and Adolescent Youth

Objectified body consciousness (OBC)—the tendency to view oneself as an object to be looked at and evaluated by others—has received recent attention as a possible vulnerability factor for depression and disordered eating. Although OBC generally is discussed in developmental terms, extant research has examined primarily the experiences of undergraduates and adults. Our goal in this study was to develop an age-appropriate measure to allow study of OBC development during preadolescence and adolescence. We modeled the OBC-Youth after McKinley and Hydes (1996) OBC-Classic to measure three components of OBC: body surveillance, body shame, and appearance control beliefs. The 14-item scale contains modified vocabulary and syntax to make it appropriate for use with preadolescent and adolescent youth. Results indicate that the OBC-Youth scale is a reliable, valid measure of OBC. Initial findings about the correlates of OBC in preadolescence are discussed.

Adolescent Gender‐Role Identity and Mental Health: Gender Intensification Revisited

Gender intensification, an increased pressure for adolescents to conform to culturally sanctioned gender roles, has been posited as an explanation for the emergence of the gender difference in depression. This longitudinal study assessed whether 410 individuals became more stereotypical in their gender-role identity across adolescence and whether such patterns predicted depressive symptoms. Girls reported higher femininity than boys at ages 11, 13, and 15, but girls and boys did not differ in masculinity. Contrary to prevailing views, there was not evidence of intensification in femininity or masculinity. Positive trajectories in masculinity for both girls and boys predicted fewer depressive symptoms, particularly at moderate levels of stress. Findings suggest a need to reconceptualize gender intensification in ways that characterize contemporary adolescence.

Excess Gestational Weight Gain in Low-Income Overweight and Obese Women: A Qualitative Study.

OBJECTIVE Examine factors implicated in gestational weight gain (GWG) in low-income overweight and obese women. DESIGN Qualitative study. SETTING Community-based perinatal center. PARTICIPANTS Eight focus groups with women (black = 48%, white non-Hispanic = 41%, and Hispanic = 10%) in the first half (n = 12) and last half of pregnancy (n = 10) or postpartum (n = 7), 2 with obstetrician-gynecologists (n = 9). PHENOMENON OF INTEREST Barriers and facilitators to healthy eating and GWG within different levels of the Social Ecological Model: for example, intrapersonal, interpersonal, and organizational. ANALYSIS Coding guide was based on the Social Ecological Model. Transcripts were coded by 3 researchers for common themes. Thematic saturation was reached. RESULTS At an intrapersonal level, knowledge/skills and cravings were the most common barriers. At an interpersonal level, family and friends were most influential. At an organizational level, the Special Supplemental Nutrition Program for Women, Infants, and Children and clinics were influential. At the community level, lack of transportation was most frequently discussed. At a policy level, complex policies and social stigma surrounding the Special Supplemental Nutrition Program for Women, Infants, and Children were barriers. There was consensus that ideal intervention approaches would include peer-facilitated support groups with information from experts. Obstetrician-gynecologists felt uncomfortable counseling patients about GWG because of time constraints, other priorities, and lack of training. CONCLUSIONS AND IMPLICATIONS There are multilevel public health opportunities to promote healthy GWG. Better communication between nutrition specialists and obstetrician-gynecologists is needed.

Individuation or Identification? Self-Objectification and the Mother–Adolescent Relationship

Do adolescents model their mothers’ self-objectification? We measured self-objectification (body surveillance and body shame), body mass index, body esteem, and quality of the mother–adolescent relationship in 179 female and 162 male adolescents at age 15, as well as self-objectification in their mothers. Initial analyses indicated no improvement in model fit if paths were allowed to differ for females and males; therefore, a single model was tested for the combined sample. Findings revealed that mothers’ body surveillance negatively predicted adolescents’ body surveillance. Mothers’ body shame was unrelated to adolescents’ body shame but positively predicted adolescents’ body surveillance. Results for the relationship between mothers’ and adolescents’ self-objectification suggest that adolescents engaged in more individuation than modeling. A more positive mother–adolescent relationship predicted lower body shame and higher body esteem in adolescents, suggesting that the quality of the relationship with the mother may be a protective factor for adolescents’ body image. Mother–adolescent relationship quality did not moderate the association between mothers’ and adolescents’ self-objectification. These findings contribute to our understanding about the sociocultural role of parents in adolescents’ body image and inform interventions addressing negative body image in this age group. The quality of the mother–adolescent relationship is a clear point of entry for such interventions. Therapists should work with adolescents and their mothers toward a more positive relationship quality, which could then positively impact adolescents’ body image.

Integrating Medical-Dental Care for Diabetic Patients: Qualitative Assessment of Provider Perspectives

Globally, periodontal disease and diabetes have achieved epidemic proportions and have become a top health care priority. Mutual bidirectional exacerbation of these conditions is promoting creation of cross-disciplinary integrated care delivery (ICD) models that bridge the traditionally siloed health care domains of dentistry and medicine. By engaging focus groups inclusive of both medical and dental providers and one-on-one interviews, this qualitative study investigated provider knowledgeability, receptiveness, and readiness to engage ICD and sought input from the medical-dental primary care practitioner participants on perceived opportunities, benefits, and challenges to achieving ICD models for patients with diabetes/prediabetes. Statewide regional representation and inclusivity of diverse practice settings were emphasized in soliciting participants. Thematic analysis of focus group and interview transcripts was undertaken to establish current state of the art, gauge receptivity to alternative ICD models, and seek insights from practitioners surrounding opportunities and barriers to ICD achievement. Forty providers participated, and thematic analyses achieved saturation. Providers were well informed regarding disease interaction; were receptive to ICD, including implementation of better screening and referral processes; and favored improving interdisciplinary communication inclusive of access to integrated electronic health records. Perceived barriers and opportunities communicated by participants for advancing ICD were documented.
