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 samples 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.

Patients’ expectations of being prescribed antibiotics can have an important influence on inappropriate prescribing. Therefore, it is important to understand the drivers of patients’ antibiotic expectations. The 2015/16 New Zealand Attitudes and Values Study measured sense of entitlement to antibiotics in a nationally representative sample of New Zealanders (n = 13,484). Participants were asked to rate their agreement with the statement “If I go to my doctor/GP with a minor illness (e.g., sore throat, cough, runny nose, etc.), I think that I should be prescribed antibiotics by default.” Eighty percent of participants showed low feelings of antibiotic entitlement, while 18.5% exhibited moderate and 3.7% high feelings of entitlement. People of ethnic minority, lower socio-economic status, and with diabetes expressed higher expectations of being prescribed antibiotics. This may be partially based on a higher risk of rheumatic fever or other complications. Men, religious people, those with lower educational attainment and self-rated health, but greater psychological distress and feelings of control over their health exhibited higher feelings of antibiotic entitlement. Those high on Extraversion, Conscientiousness, and Narcissism, but low on Agreeableness and Openness, also showed greater feelings of entitlement. Our findings help identify key characteristics of those more likely to express inappropriate expectations of antibiotic prescription.

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 sample 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.
