RESUMO
Two studies used the self-concordance model of healthy goal striving (K. M. Sheldon & A. J. Elliot, 1999) to examine the motivational processes by which people can increase their level of well-being during a period of time and then maintain the gain or perhaps increase it even further during the next period of time. In Study 1, entering freshmen with self-concordant motivation better attained their 1st-semester goals, which in turn predicted increased adjustment and greater self-concordance for the next semester's goals. Increased self-concordance in turn predicted even better goal attainment during the 2nd semester, which led to further increases in adjustment and to higher levels of ego development by the end of the year. Study 2 replicated the basic model in a 2-week study of short-term goals set in the laboratory. Limits of the model and implications for the question of how (and whether) happiness may be increased are discussed.
