stability is theoretically and statistically distinct from normative stability.
For example, the rank ordering of individuals could change substantially
over time but without any aggregate increases or decreases (e.g., if the
number of people who decreased offset the number of people who
increased). Similarly, a population could increase substantially on a trait,
but the rank ordering of individuals would be maintained if everyone
increased by the same amount. Changes in rank ordering result from
maturational or experiential factors that differentially affect people, as 620 Robins et al. well as from measurement error. Rank-order stability is commonly
assessed by the correlation between personality scores across two time
Structural stability refers to the degree of continuity in the intercorrelations among traits over time. Structural equation modeling can be used
to assess the degree to which the intercorrelations among personality
dimensions are invariant over time (Mortimer et al., 1982; see Panter,
Tanaka, & Hoyle, 1994, for a general discussion of methodological
approaches to comparing personality structure across time, measures,
and data source).
Ipsative stability refers to the degree to which the relative ordering of
traits within an individual stays the same over time. Of the four types of
stability, only ipsative stability characterizes changes that occur at the
level of the individual. Ipsative stability can be assessed by several
different indices of profile similarity, which quantify the degree to which
two profiles differ in their elevation, scatter, and shape (Cronbach &
Normative Change Although no studies have used a direct measure of the Big Five to chart
normative, or mean-level, changes in personality during the college
years, a number of studies have tracked changes on other personality
dimensions from adolescence through young adulthood. Many of these
studies focused on dimensions broadly related to Openness to Experience. For example, Plant (1965)...
