As they inhabit complex social worlds, adolescents often learn competing values, resulting in value-differentiation, within-individual variability in value importance across contexts. But what are the implications of value-differentiation across age groups and cultures? A study of 4007 adolescents aged 11 to 18 (M = 14.41, SD = 2.16), of three Israeli groups (majority, former Soviet Union immigrants, Arabs) discovered negative relations between value-differentiation and self-esteem, suggesting that confusion may result from value incoherence. The relations were stronger among younger adolescents than older ones and were especially strong among younger first-generation immigrant adolescents, pointing to the need to address the value-differentiation of immigrant adolescents.
