Some Predictors of Primary Control of Development in Three Transitional Periods of Life

In the context of some personal control (mastery) theories (e.g., J. Heckhausen & R. Schultz, 1995; Gutmann, 1964), primary, secondary, and tertiary personal control of development among subjects in three transitional periods of life were investigated (D. J. Levinson, C. N. Darrow, E. B. Klein, M. H. Levinson, & B. McKee, 1978). Results confirmed the expectation that primary control decrease whereas secondary control increase with age. Tertiary control was the same in all transitional periods. There were some differences in contribution of predictors of primary control in the early, middle, and late period of transition. From the group of variables relating to personality traits, optimism proved a good predictor of primary control in the young and middle aged, whereas in old people who have the lowest primary control, none of the personality traits proved predictive. The importance of goals related to knowledge and competence (GKC) was a significant predictor in all three (age) groups.
