Objective: We examined patterns of change and stability in the whole set of 10 Schwartz values over 2 years during early adolescence.
Method: Participants completed the Portrait Values Questionnaire repeatedly throughout the junior high school years. The study involved six waves of data and a total of 382 respondents aged 10 years at the first measurement occasion (43% female). We investigated multiple types of stability in the values: mean-level, rank-order, and ipsative stability.
Results: At the mean-level, self-enhancement, and Openness to change values increased in importance. Self-direction and hedonism values showed the greatest increase-about one-third of a standard deviation. Conservation and self-transcendence values did not change with the exception of tradition, which decreased slightly. After correcting for measurement error, rank-order stability coefficients ranged from .39 (hedonism) to .77 (power). Correlations between value hierarchies measured 2 years apart were ≥.85 for 75% of respondents, and ≤.12 for 5% of the respondents. Thus only a small proportion of participants experienced a marked change in the relative importance they ascribed to the 10 values.
Conclusions: Results are discussed and related to earlier findings on patterns and magnitude of value change during other periods of the life span.
