Abstract: Researchers have long argued that ingroup favoritism and outgroup derogation are separable phenomena that occur in different, meaningful combinations. Statistical methods for testing this thesis, however, have been underutilized. We address this oversight by using latent profile analysis (LPA) to investigate distinct profiles of group bias derived from ingroup and outgroup warmth ratings. Using a national probability s le of Māori (the indigenous people of New Zealand N = 2,289) and Europeans ( N = 13,647), we identify a distinct profile reflecting ingroup favoritism/outgroup derogation (Type III in Brewer’s typology of ingroup bias) in both groups (6.7% of Māori, 10.3% of Europeans). The factors associated with this type, however, differed between groups. Whereas ethnic identity centrality predicted membership for Type III for Māori, social dominance orientation predicted this type for Europeans. Thus, although both groups may express the same kind of bias pattern, the motivation underlying this bias varies by status.

Abstract: In this study, we asked participants to "describe their sexual orientation" in an open-ended measure of self-generated sexual orientation. The question was included as part of the New Zealand Attitudes and Values Study (N = 18,261) 2013/2014 wave, a national probability survey conducted shortly after the first legal same-sex marriages in New Zealand. We present a two-level classification scheme to address questions about the prevalence of, and demographic differences between, sexual orientations. At the most detailed level of the coding scheme, 49 unique categories were generated by participant responses. Of those who responded with the following, significantly more were women: bisexual (2.1 % of women, compared to 1.5 % of men), bicurious (0.7 % of women, 0.4 % of men), and asexual (0.4 % of women and less than 0.1 % of men). However, significantly fewer women than men reported being lesbian or gay (1.8 % of women, compared to 3.5 % of men). Those openly identifying as bicurious, bisexual, or lesbian/gay were significantly younger than those with a heterosexual orientation. This study shows ersity in the terms used in self-generated sexual orientations, and provides up-to-date gender, age, and prevalence estimates for the New Zealand population. Finally, results reveal that a substantial minority of participants may not have understood the question about sexual orientation.

Abstract: Is it possible to predict COVID-19 vaccination status prior to the existence and availability of COVID-19 vaccines? Here, we present a logistic model by regressing decisions to vaccinate in late 2021 on lagged sociodemographic, health, social, and political indicators from 2019 in a s le of New Zealand adults aged between 18 and 94 (Mage = 52.92, SD = 14.10 62.21% women N = 5324). We explain 31% of the variance in decision making across New Zealand. Significant predictors of being unvaccinated were being younger, more deprived, reporting less satisfaction with general practitioners, lower levels of neuroticism, greater levels of subjective health and meaning in life, higher distrust in science and in the police, lower satisfaction in the government, as well as political conservatism. Additional cross-sectional models specified using the same, and additional COVID-19-specific factors are also presented. These findings reveal that vaccination decisions are neither artefacts of context nor chance, but rather can be predicted in advance of the availability of vaccines.

Abstract: Research indicates COVID-19 lockdowns elevated psychological distress. Here, we leverage national panel data before and during New Zealand’s COVID-19 lockdown to clarify distress buffers (2018/2020, N = 940). To distinguish lockdown-related distress from natural disasters, we investigate distress dynamics following the Christchurch earthquakes (2011, N = 6,806). During lockdown, there were small increases in hopelessness, restlessness, and nervousness, and substantial increases in worthlessness. A sense of neighbourhood community became decoupled from this distress, which high levels of social belonging and health satisfaction did not prevent. A silver lining was a relief from feelings of effort fostered by social belonging. By contrast, the Christchurch earthquakes increased all distress indicators and distress buffers performed consistently. We infer that losses of employment and social routines during New Zealand’s lockdown, in a setting of government income and health protections, precipitated bittersweet mental health dynamics. That certain pandemic mental health burdens are avoidable has applied interest.

Abstract: New Zealand's COVID-19 lockdown in March and April 2020 was among the world's most stringent. Similar to other countries, New Zealand's lockdown occurred amidst pervasive health and economic uncertainties. However, New Zealanders experienced comparatively less psychological distress. To test theories of pandemic distress mitigation, we use national longitudinal responses with pre-COVID-19 baselines and systematically quantify psychological distress trajectories within the same in iduals during the lockdown (pre-COVID-19 = 2018/2019 stringent-lockdown = March/April 2020 N = 940). Most distress indicators were minimally elevated. However, there was a three-fold increase in feelings of worthlessness. Neither satisfaction with the government, nor business-satisfaction, nor a sense of neighbourhood community were effective distress defences. Perceived social-belonging and health-satisfaction mitigated feelings of worthlessness. A silver lining was a relief from feelings of effort, which social-belonging fostered. That social-belonging and health satisfaction could quell serious distress among those low in government confidence, low in business satisfaction, and low neighbourhood community proves that distress mitigation is possible without shifting a population's general political, economic, and civic attitudes. Protection of income and containment of infectious disease threat reduces mental health burdens. Though feelings of worthlessness surge during lockdown, such feelings attenuate from interpersonal belonging with people one already knows.

Abstract: The contagiousness and deadliness of COVID-19 have necessitated drastic social management to halt transmission. The immediate effects of a nationwide lockdown were investigated by comparing matched s les of New Zealanders assessed before (Npre-lockdown = 1,003) and during the first 18 days of lockdown (Nlockdown = 1,003). Two categories of outcomes were examined: (1) institutional trust and attitudes towards the nation and government, and (2) health and wellbeing. Applying propensity score matching to approximate the conditions of a randomized controlled experiment, the study found that people in the pandemic/lockdown group reported higher trust in science, politicians, and police, higher levels of patriotism, and higher rates of mental distress compared to people in the pre-lockdown pre-pandemic group. Results were confirmed in within-subjects analyses. The study highlights social connectedness, resilience, and vulnerability in the face of adversity, and has applied implications for how countries face this global challenge.

Abstract: Although the social identity model of collective action (SIMCA) demonstrates that identity, efficacy, and injustice are key correlates of collective action, longitudinal tests of these causal assumptions are absent from the literature. Moreover, most collective action research focuses on disadvantaged groups’ responses to injustice, with few studies examining what motivates advantaged groups to protest. We address these oversights using nationally representative longitudinal panel data to investigate SIMCA among members of disadvantaged ( N = 2,574) and advantaged ( N = 13,367) groups. As hypothesized, identity predicted increases in injustice, efficacy, and collective action support over time. In turn, injustice (but not efficacy) mediated the longitudinal association between identity and collective action support. Notably, results were largely consistent across disadvantaged and advantaged groups. Thus, we provide the first demonstration that identity temporally precedes collective action across objectively disadvantaged and advantaged groups, but identify complexities regarding the role of efficacy in protest.

Abstract: We leverage powerful time-series data from a national longitudinal s le measured before the COVID-19 pandemic and during the world’s eighth most stringent COVID-19 lockdown (New Zealand, March-April 2020, N = 940) and apply Bayesian multilevel mediation models to rigorously test five theories of pandemic distress. Findings: (1) during lockdown, rest diminished distress without rest psychological distress would have been ~ 1.74 times greater (2) an elevated sense of community reduced distress, a little, but elevated government satisfaction was inert. Thus, the psychological benefits of lockdown extended to political discontents (3) most lockdown distress arose from dissatisfaction from personal relationships. Social captivity, more than isolation, proved challenging (4-5) Health and business satisfaction were stable were they challenged substantially more distress would have ensued. Thus, lockdown benefited psychological health by affording safety, yet only because income remained secure. These national longitudinal findings clarify the mental health effects of stringent infectious disease containment.

Abstract: Although Benevolent Sexism (BS)—an ideology that highly reveres women who conform to traditional gender roles—is cloaked in a superficially positive tone, being placed upon a pedestal is inherently restrictive. Accordingly, because the paternalistic beliefs associated with BS are based on the idealization of traditional gender roles (which include motherhood), BS should predict people’s attitudes toward women’s reproductive rights. Using data from a nationwide longitudinal panel study ( N = 12,299), Study 1 showed that BS (but not Hostile Sexism) had cross-lagged effects on opposition to both elective and traumatic abortion. Study 2 ( N = 309) extended these findings by showing that the relationship between BS and support for abortion was fully mediated by attitudes toward motherhood. These results highlight the pernicious nature of BS by demonstrating that the idealization of women—and motherhood, in particular—comes at a substantial cost (namely, the restriction of women’s reproductive rights).

Abstract: The aim of the current research is to test predictions derived from the rejection-identification model and research on collective action using cross-sectional (Study 1) and longitudinal (Study 2) methods. Specifically, an integration of these 2 literatures suggests that recognition of discrimination can have simultaneous positive relationships with well-being and engagement in collective action via the formation of a strong ingroup identity. We test these predictions in 2 studies using data from a large national probability s le of Māori (the indigenous peoples of New Zealand), collected as part of the New Zealand Attitudes and Values Study (Ns for Study 1 and 2 were 1,981 and 1,373, respectively). Consistent with the extant research, Study 1 showed that perceived discrimination was directly linked with decreased life satisfaction, but indirectly linked with increased life satisfaction through higher levels of ethnic identification. Perceived discrimination was also directly linked with increased support for Māori rights and indirectly linked with increased support for Māori rights through higher levels of ethnic identification. Study 2 replicated these findings using longitudinal data and identified multiple bidirectional paths between perceived discrimination, ethnic identity, well-being, and support for collective action. These findings replicate and extend the rejection-identification model in a novel cultural context by demonstrating via cross-sectional (Study 1) and longitudinal (Study 2) analyses that the recognition of discrimination can both motivate support for political rights and increase well-being by strengthening ingroup identity.
