Most of the women in our sample reported mild sleep disturbances through the perinatal period. A subgroup of women reported a significant decline in sleep quality from early to late pregnancy and another reported poor subjective sleep quality throughout pregnancy; these groups had the greatest risk of experiencing high symptoms of depression in the postpartum period.

We examined perceptions of cross-class heterosexual couples, that is, couples where couple members differ in social class. Informed by social dominance theory, system justification theory, and equity theory, we predicted that (a) cross- (vs. same-) class couples would be perceived more negatively, (b) cross-class couples with the woman (vs. the man) in the higher class position would be evaluated more negatively, and (c) same-class low-low (vs. high-high) couples would be evaluated more negatively. We examined perceptions of cross-income, cross-education, and cross-occupation status relationships. We found support for our predicted patterns, with some exceptions. In general, high-high class couples were preferred. In three of four studies, a higher-class woman paired with a lower-class man was evaluated most negatively of all couples. Recognition of this prejudice may explain challenges faced by certain couples and couple members; as such, implications for clinicians and counselors are discussed. Further, our research generates directions for future research.

Republican or Democrat participants imagined how they would respond upon learning about the political group membership of a potential or established friend. Four vignettes (friend political in-group; friend political out-group; potential friend political in-group; potential friend political out-group) were presented in a random order. After each, participants provided expected reactions. Overall, reactions (e.g., hope of the relationship lasting, intentions to engage in friendship maintenance behaviors, trust) were most positive toward the established in-group friend, followed by potential in-group friend, then the established out-group friend, and lastly the potential out-group friend. That is, participants expected to be more positive toward a person they just met than an established close friend, simply due to knowing these individuals’ political group memberships. Some of these differences were moderated by intergroup attitudes or political identification. Discoveries of political group membership may influence the development or maintenance of friendships.

In the domain of political affiliation, negative intergroup attitudes are widespread. In the United States, Republicans generally hold negative attitudes toward Democrats and Democrats generally hold negative attitudes toward Republicans (Iyengar et al., 2012). Some evidence suggests that antipathy toward one's political outgroup, especially in the United States, has increased in recent years (Iyengar & Krupenkin, 2018; Pew Research Center, 2017). The percentage of Americans who characterized the conflicts between Democrats and Republicans to be very strong has increased substantially from 47%
