Unformatted text preview: e of .54 found for personality traits during the college years
(Roberts & DelVecchio, 2000). Disattenuated coefficients (corrected for
coefficient alpha reliability estimates) ranged from .63 for Neuroticism
to .92 for Openness.
Differences among the Big Five in their 4-year stabilities may reflect
differences in the degree to which these dimensions exhibit short-term
fluctuations over time. For example, it is possible that Neuroticism is less
stable than Openness because Neuroticism shows greater week-by-week
fluctuations than Openness. To explore this possibility, we used shortterm test-retest reliability estimates to compute stability coefficients for
each of the Big Five. The disattenuated 4-year stability correlations were
.73 (Extraversion), .70 (Agreeableness), .66 (Conscientiousness),
.60 (Neuroticism), and .80 (Openness). These stability estimates are
consistent with (albeit a little lower than) the stabilities found when
coefficient alpha was used to disattenuate the correlations (see Table 1).
Structural Stability of Personality The intercorrelations among the Big Five scales at the beginning and end
of college were highly similar both in terms of their absolute level and
their patterning (see Table 2). The mean intercorrelation at Week 1 was Personality Change 629 Table 2
