• Abstract We examined four types of stability and change in values during young adulthood. 270 respondents (aged 20–28, 54% female) completed the Portrait Values Questionnaire at three time points, separated by 4 years. Rank-order stability coefficients of the 10 values averaged 0.69 (T1-T2) and 0.77 (T2-T3). The mean importance of conservation, self-transcendence, and power values increased over time, the mean importance of achievement values decreased, and openness to change values remained stable. For 75% of respondents, the correlations of the within-person value hierarchies exceeded 0.45 from T1 to T2 and 0.61 from T2 to T3. Correlations among individual change scores for the 10 values formed coherent patterns of value change that mirror the circular structure of Schwartz’s theory.
