“…Campbell et al () theorized SCC as a type of individual difference that exhibits high levels of temporal stability, although it is susceptible to contextual influences. Thus, like other personality traits (Caspi, Roberts, & Shiner, ; Roberts, Walton, & Viechtbauer, ), though many aspects of the self‐concept may be stable across time and situations, they also might mature over time and change in response to important life experiences and transitions (Light & Visser, ; Lodi‐Smith & Roberts, ; Nezlek & Plesko, ). So, high levels of relative stability (i.e., the degree to which the relative differences among individuals remain the same over time) may go together with changes in absolute stability (i.e., the extent to which personality scores change over time; e.g., Santor, Bagby, & Joffe, ).…”
