A research synthesis was conducted with four studies which correlated natio
nal mean self-ratings of affect balance (positive minus negative affect) an
d subjective well-being with the nations' cultural characteristics (individ
ualism, masculinity, uncertainty avoidance, and power-distance national sco
res on Hofstede's dimensions), socioeconomic development (Human Development
Index), and climate (absolute latitude). A meta-analysis of these collecti
ve level cross-cultural studies shows that individualism correlates positiv
ely with affect balance and subjective well-being, controlling for socioeco
nomic development, cultural femininity, power-distance, uncertainty avoidan
ce, and climate. Similar results were found for individual-level data. The
meaning of collective-level or national means of individual self-reports of
affect balance is discussed.
