Abstract: To measure the global impact of COVID-19 pandemic on volumes of IV thrombolysis (IVT), IVT transfers, and stroke hospitalizations over 4 months at the height of the pandemic (March 1 to June 30, 2020) compared with 2 control 4-month periods. We conducted a cross-sectional, observational, retrospective study across 6 continents, 70 countries, and 457 stroke centers. Diagnoses were identified by their ICD-10 codes or classifications in stroke databases. There were 91,373 stroke admissions in the 4 months immediately before compared to 80,894 admissions during the pandemic months, representing an 11.5% (95% confidence interval [CI] −11.7 to −11.3, p 0.0001) decline. There were 13,334 IVT therapies in the 4 months preceding compared to 11,570 procedures during the pandemic, representing a 13.2% (95% CI −13.8 to −12.7, p 0.0001) drop. Interfacility IVT transfers decreased from 1,337 to 1,178, or an 11.9% decrease (95% CI −13.7 to −10.3, p = 0.001). Recovery of stroke hospitalization volume (9.5%, 95% CI 9.2–9.8, p 0.0001) was noted over the 2 later (May, June) vs the 2 earlier (March, April) pandemic months. There was a 1.48% stroke rate across 119,967 COVID-19 hospitalizations. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection was noted in 3.3% (1,722/52,026) of all stroke admissions. The COVID-19 pandemic was associated with a global decline in the volume of stroke hospitalizations, IVT, and interfacility IVT transfers. Primary stroke centers and centers with higher COVID-19 inpatient volumes experienced steeper declines. Recovery of stroke hospitalization was noted in the later pandemic months.

Abstract: Societal threats that face the world today seem overpowering, especially for young generations who will need to develop creative solutions. The present study examined the relationships between societal threats and social motives. Social motives function to orient in iduals toward the social world and prepare them to engage socially. This adaptive function of social motives may be particularly useful when threats are looming in the environment. We thus expected that perceived societal threats would correlate positively with activation of social motives, especially among in iduals with lower self‐esteem, who tend to show higher interdependency when threatened. Our cross‐cultural s les from Australia, the United States, New Zealand, the Philippines, China (Macao), Malaysia (Sabah), and Austria ( N = 1,269) showed evidence to support these expectations. Perceived societal threats correlated positively with all social motives (Belong, Understand, Control, Esteem, and Trust) however, the link was most vital for the Control motive, and especially in the United States and China. In line with our expectations, higher perceived societal threats were associated with more robust social motives, especially among those with low self‐esteem. Potential mechanisms through which social motives assist adaptation to societal threats and country‐specific contents of threats are discussed.

Abstract: A new scale to measure core social motives was developed based on the BUC(K)ET framework (Belong, Understand, Control, Esteem, and Trust). The scale was completed by 1,516 university students from seven countries: Australia, the United States, New Zealand, the Philippines, Malaysia, China (Macao), and Austria. Multigroup confirmatory factor analysis supported the scale's full scalar invariance between Australia and the United States and between Australia and Austria. Partial scalar invariance was established for all countries after omitting the Understand motive, suggesting that the remaining four subscales can be used to compare levels of social motives across erse cultural groups with caution. We further established the scale's construct validity by examining its correlations in the nomological networks involving several in idual difference variables. The profile of social motives was remarkably similar across countries and gender groups, although three Asian groups showed higher motives to belong than non‐Asian groups, and women showed generally stronger core social motives than men, especially the Belong motive. Implications and possible directions of research are discussed.
