Did relationship quality during the COVID-19 pandemic vary across cultural contexts?

We examined whether the impact of the pandemic on couple relationships varied across cultural contexts. Following from studies showing better outcomes (lower disease risk, greater well-being) within cultures higher in tightness (having strong norms promoting conformity) or collectivism (vs. individualism), we predicted that tighter and more collectivistic contexts would be associated with better relationship functioning. Preregistered analyses using existing data collected during the pandemic (N = 2510; 12 countries), indicated, counter to predictions, that individuals from countries higher in tightness or collectivism evidenced greater relationship conflict. Cultural context was unrelated to relationship quality. Stress, attachment insecurity, and perceived partner responsiveness predicted relationship quality during the pandemic, but cultural context generally did not moderate these links. Perceived partner responsiveness, however, predicted relationship quality more strongly within more collectivistic (vs. more individualistic) countries. We discuss possible explanations for these findings, limitations of the data, and the need for larger studies including a broader range of countries, individuals, and cultural contexts.
