Rumination is engaging in a passive focus on one's symptoms of distress and on the possible causes and consequences of these symptoms. Women are more likely than men to engage in rumination. This study examined whether gender differences in the following beliefs would mediate the gender difference in rumination: the controllability of emotions, the appropriateness of rumination as a coping strategy, responsibility for the emotional tone of relationships, and mastery over negative events. The sample was 740 community-dwelling adults between 25 and 75 years of age, who completed a survey by mail. The combination of beliefs about control of emotions, responsibility for the emotional tone of relationships, and mastery over negative events fully mediated the gender difference in rumination. Alternative hypotheses that the gender difference in rumination was due to gender differences in distress, emotional expressivity, and the tendency to give socially desirable answers were not supported.Note: Percentages are based on non-missing cases. Percentages may not add to 100 because of rounding error.

In this review, we explore social contagion as an understudied risk factor for non-suicidal self-injury (NSSI) among adolescents and young adults, populations with a high prevalence of NSSI. We review empirical studies reporting data on prevalence and risk factors that, through social contagion, may influence the transmission of NSSI. Findings in this literature are consistent with social modeling/learning of NSSI increasing risk of initial engagement in NSSI among individuals with certain individual and/or psychiatric characteristics. Preliminary research suggests iatrogenic effects of social contagion of NSSI through primary prevention are not likely. Thus, social contagion factors may warrant considerable empirical attention. Intervention efforts may be enhanced, and social contagion reduced, by implementation of psychoeducation and awareness about NSSI in schools, colleges, and treatment programs.

A growing body of research documents multiple health disparities by sexual orientation among women, yet little is known about the possible causes of these disparities. One underlying factor may be heightened risk for abuse victimization in childhood in lesbian and bisexual women. Using survey data from 63,028 women participating in the Nurses' Health Study II, we investigated sexual orientation group differences in emotional, physical, and sexual abuse in childhood and adolescence. Multivariable log-binomial and linear regression models were used to examine orientation group differences in prevalence and severity of abuse, with heterosexual as the referent and controlling for sociodemographics. Results showed strong evidence of elevated frequency, severity, and persistence of abuse experienced by lesbian and bisexual women. Comparing physical abuse victimization occurring in both childhood and adolescence, lesbian (30%; prevalence ratio [PR] 1.61; 95% confidence interval [CI] 1.40, 1.84) and bisexual (24%; PR 1.26; 95% CI 1.00, 1.60) women were more likely to report victimization than were heterosexual women (19%). Similarly, comparing sexual abuse victimization occurring in both age periods, lesbian (19%; PR 2.16; 95% CI 1.80, 2.60) and bisexual (20%; PR 2.29; 95% CI 1.76, 2.98) women were more likely to report victimization than were heterosexual women (9%). This study documents prevalent and persistent abuse disproportionately experienced by lesbian and bisexual women.

Can perceiving unfairness influence physical health? To address this question the authors propose the Perceived Unfairness Model, synthesized from psychological and epidemiological research. The model starts from the premise that perceiving unfairness, directed at beings to which the perceiver is emotionally attached, activates a cascade of psychological and physical processes. This cascade may be experienced by low or high status group members, and by the target or observer of the perceived unfairness. With repeated episodes, the effects of perceiving unfairness may accumulate and compromise physical health. Whether perceiving unfairness is potentially toxic or benign is a function of two key components of social location: identity relevance and helplessness to redress the unfairness. The authors conclude by discussing directions for developing the model.
