Ka. Sheldon et T. Kasser, Getting older, getting better? Personal strivings and psychological maturity across the life span, DEVEL PSYCH, 37(4), 2001, pp. 491-501
Measures of psychological maturity based on personal strivings (R. A. Emmon
s, 1989) were administered to 108 adults aged 17-82. On the basis of organi
smic-theoretical assumptions regarding maturity, age was hypothesized to be
positively associated with K. M. Sheldon and T. Kasser's (1995, 1998) two
goal-based measures of personality integration. E. Erikson's (1963) assumpt
ions regarding maturity were the basis for the hypothesis that older people
would tend to list more strivings concerning generativity and ego integrit
y and fewer strivings concerning identity and intimacy. Finally, on the bas
is of past research findings, maturity and age were hypothesized to be posi
tively associated with subjective well-being. Results supported these hypot
heses and also showed that measured maturity mediated the relationship betw
een age and well-being, Thus, older individuals may indeed be more psycho l
ogically mature than younger people and may be happier as a result.
