Where and with whom does a brief social-belonging intervention promote progress in college?

A promising way to mitigate inequality is by addressing students' worries about belonging. But where and with whom is this social-belonging intervention effective? Here we report a team-science randomized controlled experiment with 26,911 students at 22 diverse institutions. Results showed that the social-belonging intervention, administered online before college (in under 30 minutes), increased the rate at which students completed the first year as full-time students, especially among students in groups that had historically progressed at lower rates. The college context also mattered: The intervention was effective only when students' groups were afforded opportunities to belong. This study develops methods for understanding how student identities and contexts interact with interventions. It also shows that a low-cost, scalable intervention generalizes its effects to 749 4-year institutions in the United States.

The Countervailing Effects of Weight Stigma on Weight-Loss Motivation and Perceived Capacity for Weight Control.

We hypothesized that exposure to weight stigma simultaneously increases motivation to lose or avoid gaining weight to avoid future stigma and decreases perceived capacity to do so, by heightening concerns about experiencing stigma and negative affect. Study 1 showed that more frequently experiencing weight-based discrimination was associated with greater concerns about being a victim of weight stigma, which predicted increased motivation to lose weight but decreased perceived capacity for weight control. Study 2 showed that participants randomly assigned to view a weight-stigmatizing (vs. control) message showed increased concerns about being a target of weight stigma, which indirectly increased motivation to lose weight and decreased state self-control. These, in turn, predicted increased willingness to engage in unhealthy weight-loss behaviors and decreased perceived capacity for weight control, respectively. Study 3 showed that increased motivation to avoid stigma and increased negative affect mediate these effects of exposure to weight stigma.

An educational intervention to improve women's academic STEM outcomes: Divergent effects on well-represented vs. underrepresented minority women.

OBJECTIVES: The aim of this field experiment was to test the effect of a social psychological intervention on an ethnically diverse sample of first-year college women majoring in science, technology, engineering, and math (STEM). We hypothesized that grade point averages in STEM courses would be higher in the intervention condition relative to the control condition. Furthermore, we tested competing hypotheses about the moderating role of belonging to either a well-represented (WR) or underrepresented minority (URM) ethnic group in STEM. METHOD: The sample (N = 199) included 115 women from WR ethnic groups and 84 women from URM ethnic groups who were randomly assigned to condition. Women in the intervention were educated about the harmful impact of gender stereotypes in STEM and provided with effective strategies for coping with stereotype threat. At the end of their first year, we obtained participants' academic transcripts. RESULTS: At the end of their first year in college, URM women in the intervention condition had higher grade point averages in their STEM courses than URM women in the control condition. The intervention had no effect on WR women. CONCLUSIONS: The present research demonstrates the importance of intersectional approaches to studying the experiences of women in STEM.

The psychological and physiological effects of interacting with an anti-fat peer.

This experiment tested whether interacting with a peer who holds explicitly anti-fat attitudes leads to cognitive performance deficits and poorer psychological and cardiovascular outcomes among higher body weight women by increasing anticipated rejection. One hundred and forty six higher body weight women were randomly assigned to interact in a non-romantic context with a same-sex peer who endorsed explicit anti-fat or unbiased attitudes. All women showed greater heart rate reactivity and anger when interacting with an anti-fat peer. The heavier women were, and the more they thought they were overweight, the more they anticipated rejection when interacting with an anti-fat peer. This anticipated rejection was in turn associated with poorer cognitive performance, lower state self-esteem, and increased negative emotions, rumination, compensatory efforts, and thoughts related to anxiety and evaluation. These effects were not observed among women in our sample categorized as slightly "overweight" or who perceived themselves as only slightly overweight.

Perceived discrimination and poor health: Accounting for self-blame complicates a well-established relationship.

Past research has reliably demonstrated that both perceiving oneself as a target of discrimination and a tendency to blame negative events on oneself undermine psychological and physical health. These two literatures, however, have evolved largely independently of one another. The present research sought to develop a deeper understanding of the health effects of perceived discrimination by taking into account the relationship between perceived discrimination and self-blame. In two correlational studies, we examined perceived ethnic-based discrimination, self-blame, and psychological and physical health among White and ethnic minority adults residing in the United States. Contrary to the hypothesis that attributing negative events to discrimination leads to the discounting of self-blame, perceived discrimination and self-blame were positively related. Replicating past research, perceived discrimination was negatively related to health when examined as an independent predictor. When perceived discrimination and self-blame were examined as simultaneous predictors of health, however, the negative health effects of perceived discrimination were weakened. Furthermore, an alternative model revealed that perceived discrimination indirectly predicted decreased health through increased self-blame. The present findings highlight the importance of taking self-blame into account when assessing and interpreting the negative health effects of perceived discrimination.

Unpacking the psychological weight of weight stigma: A rejection-expectation pathway.

The present research tested the hypothesis that the negative effects of weight stigma among higher body-weight individuals are mediated by expectations of social rejection. Women and men who varied in objective body-weight (body mass index; BMI) gave a speech describing why they would make a good date. Half believed that a potential dating partner would see a videotape of their speech (weight seen) and half believed that a potential dating partner would listen to an audiotape of their speech (weight unseen). Among women, but not men, higher body-weight predicted increased expectations of social rejection, decreased executive control resources, decreased self-esteem, increased self-conscious emotions and behavioral displays of self-consciousness when weight was seen but not when weight was unseen. As predicted, higher body-weight women reported increased expectations of social rejection when weight was seen (versus unseen), which in turn predicted decreased self-esteem, increased self-conscious emotions, and increased stress. In contrast, lower body-weight women reported decreased expectations of social rejection when weight was seen (versus unseen), which in turn predicted increased self-esteem, decreased self-conscious emotions, and decreased stress. Men's responses were largely unaffected by body-weight or visibility, suggesting that a dating context may not be identity threatening for higher body-weight men. Overall, the present research illuminates a rejection-expectation pathway by which weight stigma undermines higher body-weight women's health.

Weighed down by stigma: How weight-based social identity threat contributes to weight gain and poor health.

Weight stigma is pervasive, and a number of scholars argue that this profound stigma contributes to the negative effects of weight on psychological and physical health. Some lay individuals and health professionals assume that stigmatizing weight can actually motivate healthier behaviors and promote weight loss. However, as we review, weight stigma is consistently associated with poorer mental and physical health outcomes. In this article we propose a social identity threat model elucidating how weight stigma contributes to weight gain and poorer mental and physical health among overweight individuals. We propose that weight-based social identity threat increases physiological stress, undermines self-regulation, compromises psychological health, and increases the motivation to avoid stigmatizing domains (e.g., the gym) and escape the stigma by engaging in unhealthy weight loss behaviors. Given the prevalence of overweight and obesity in the US, weight stigma thus has the potential to undermine the health and wellbeing of millions of Americans.

Ethnic variation in gender-STEM stereotypes and STEM participation: an intersectional approach.

Stereotypes associating men and masculine traits with science, technology, engineering, and mathematics (STEM) fields are ubiquitous, but the relative strength of these stereotypes varies considerably across cultures. The present research applies an intersectional approach to understanding ethnic variation in gender-STEM stereotypes and STEM participation within an American university context. African American college women participated in STEM majors at higher rates than European American college women (Study 1, Study 2, and Study 4). Furthermore, African American women had weaker implicit gender-STEM stereotypes than European American women (Studies 2-4), and ethnic differences in implicit gender-STEM stereotypes partially mediated ethnic differences in STEM participation (Study 2 and Study 4). Although African American men had weaker implicit gender-STEM stereotypes than European American men (Study 4), ethnic differences between men in STEM participation were generally small (Study 1) or nonsignificant (Study 4). We discuss the implications of an intersectional approach for understanding the relationship between gender and STEM participation.
