Happiness around the world: A combined etic-emic approach across 63 countries

What does it mean to be happy? The vast majority of cross-cultural studies on happiness have employed a Western-origin, or "WEIRD" measure of happiness that conceptualizes it as a self-centered (or "independent"), high-arousal emotion. However, research from Eastern cultures, particularly Japan, conceptualizes happiness as including an interpersonal aspect emphasizing harmony and connectedness to others. Following a combined emicetic approach (Cheung, van de Vijver & Leong, 2011), we assessed the cross-cultural applicability of a measure of independent happiness developed in the US (Subjective Happiness Scale; Lyubomirsky & Lepper, 1999) and a measure of interdependent happiness developed in Japan (Interdependent Happiness Scale; Hitokoto & Uchida, 2015), with data from 63 countries representing 7 sociocultural regions. Results indicate that the schema of independent happiness was more coherent in more WEIRD countries. In contrast, the coherence of interdependent happiness was unrelated to a country's "WEIRD-ness." Reliabilities of both happiness measures were lowest in African and Middle Eastern countries, suggesting these two conceptualizations of happiness may not be globally comprehensive. Overall, while the two measures had many similar correlates and properties, the self-focused concept of independent happiness is "WEIRD-er" than interdependent happiness, suggesting cross-cultural researchers should attend to both conceptualizations

International optimism: Correlates and consequences of dispositional optimism across 61 countries

Objective: The current exploratory study sought to examine dispositional optimism, or the general expectation for positive outcomes, around the world. Method: Dispositional optimism and possible correlates were assessed across 61 countries (N = 15,185; mean age = 21.92; 77% female). Mean-level differences in optimism were computed along with their relationships with individual and country-level variables. Results: Worldwide, mean optimism levels were above the midpoint of the scale. Perhaps surprisingly, country-level optimism was negatively related to gross domestic product per capita, population density, and democratic norms and positively related to income inequality and perceived corruption. However, country-level optimism was positively related to projected economic improvement. Individual-level optimism was positively related to individual well-being within every country, although this relationship was less strong in countries with challenging economic and social circumstances. Conclusions: While individuals around the world are generally optimistic, societal characteristics appear to affect the degree to which their optimism is associated with psychological well-being, sometimes in seemingly anomalous ways
