Residential mobility, personality, and subjective and physical well-being: An analysis of cortisol secretion

Frequent residential moves in childhood may be stressful. Because introverts find making new friends in a new town more difficult than extraverts, the authors predicted that residential moves would be more negatively associated with well-being among introverts than among extraverts. To test this hypothesis, the authors collected salivary cortisol samples from morning to evening for two consecutive days, in addition to self-reports of well-being. In general, the authors found support for this prediction among European American participants but not for African Americans or Asian Americans. Extraversion seems to buffer the stress of residential moves among European Americans, whereas it does not seem to play as important a role to this end among African and Asian Americans.
