Horizontal Collectivism Predicts Perceived Social Support, Higher Friendship Quality, and Lower Ostracism Among Young Adults

This study examined whether collectivistic cultural orientations predict friendship quality, perceived social support, and ostracism in young adults within a U.S. sample (N = 1,137). We found that horizontal collectivism consistently predicted positive social outcomes. The findings reinforce the importance of cultural orientation in shaping social well-being.
