Does Major Depression Differentially Affect Daily Affect in Adults From Six Middle-Income Countries: China, Ghana, India, Mexico, Russian Federation, and South Africa?

Much of the research on how depression affects daily emotional functioning comes from Western, Educated, Industrialized, Rich, and Democratic (WEIRD) countries. In the current study, we investigated daily positive affect (PA) and negative affect (NA) and PA and NA variability in a cross-cultural sample of adults with a depression diagnosis ( N = 2,487) and without a depression diagnosis ( N = 31,764) from six middle-income non-WEIRD countries: China, Ghana, India, Mexico, Russian Federation, and South Africa. Across countries, adults with depression relative to adults without depression reported higher average NA and NA variability and lower average PA but higher PA variability. Findings varied between countries. Observations are discussed within the context of new theories and evidence. Implications for current knowledge and for future efforts to grow cross-cultural and non-WEIRD affective science are discussed.
