traits related to Conscientiousness. Similarly, the college environment
exposes individuals to a diverse set of ideas, people, and cultural traditions, as well as sparking their curiosity and stimulating them to consider
a wider range of perspectives and values. At the same time, maturational
changes occurring during late adolescence may promote independence
from one’s parents; exploration of new identities, roles, and relationships;
and goal-oriented behaviors that facilitate successful adaptation to adult
society (Arnett, 2000). Thus, increases in Conscientiousness and Openness could reflect experiential factors associated with college, intrinsic
maturational factors, or both. Disentangling these accounts requires
research using a non-college student control sample. Personality Change 633 Longitudinal studies based on only two waves of data present several
limitations in the study of stability and change (e.g., Bryk & Raudenbush,
1987; Jones & Meredith, 1996; Rogosa, 1995; Rogosa, Brandt, &
Zimowski, 1982; Willett, Singer, & Martin, 1998). First, estimates of the
amount of change from two-wave studies can be highly unreliable. The
reliability of a change trajectory increases substantially up to six or seven
waves of data and then gradually begins to asymptote (Willett, Singer, &
Martin, 1998, Figure 4). Thus, studies in which personality change is
modeled across multiple waves of data are greatly needed.
Second, the amount of change demonstrated by two-wave longitudinal
studies can be misleading because decisions about when the Time 1 and
Time 2 measurements occur are highly consequential, and observations
over alternative time periods may yield quite different findings (Rogosa,
1995). For example, our findings regarding change in Neuroticism might
have been different if our first personality assessment had been 1 month
earlier (i.e., prior to entry into college). Specifically, it is possible that
individuals experience a temporary elevation in their Neuroticism scores
during the transition to college and that this ar...
