Ethics-relevant values in adulthood: Longitudinal findings from the life and time study

OBJECTIVE: This study investigates a set of variables related to the relative valuing of narrow self-interest versus the concerns of a larger community. These values likely capture stable dispositions. Additionally, because ethics-relevant values are associated with ongoing cultural and moral socialization, they may develop over time as in May's theory of "mature" values. METHOD: We administered eight value priority scales (Mature Values, Unmitigated Self-Interest, Materialism, Financial Aspirations, and Horizontal and Vertical Individualism and Collectivism) to a national community sample (N = 864, 66% female, 71% White, mean age 36) on four occasions approximately one year apart (Time 4 N = 570). We examined the mean-level change as cross-sectional age differences and longitudinal change, and rank-order stability. Correlations with Big Five/Big Six personality traits are reported. RESULTS: As people grew older, they increased in Mature Values and Horizontal and Vertical Collectivism, and decreased in Unmitigated Self-Interest, Materialism, and Vertical Individualism. Rank-order stability of the values was nearly as high as personality traits over three years. Stability increased with age for some scales. DISCUSSION: The stability of values scores suggests that they capture dispositional aspects, but age differences and longitudinal trends are also consistent with the hypothesis of socialization toward more inclusive value priorities
