Young adults (202 women, 61 men: M = 20.9) completed measures of decisional and behavioral procrastination, self-esteem, interpersonal dependency, and self-defeating behavior. Correlational analysis indicated that both procrastination types separately and combined were significantly related to low self-esteem, dependency on others, and defeating behaviors. Among specific self-defeating behaviors, decisional procrastination was related to failing to complete crucial tasks, inciting anger in others, and rejecting good-spirited others. Behavioral procrastination was related to failing task completion, rejecting well-minded others, feeling guilty after a positive event, and choosing handicapping situations. Multiple regression analyses indicated that self-defeating tendencies of failure to complete crucial tasks and rejecting opportunities for pleasure were significant predictors of decisional, behavioral, and overall dysfunctional procrastination. Interpersonal dependency also was a significant predictor of both decisional and dysfunctional procrastination, while self-esteem predicted behavioral procrastination. These results suggest that types of procrastination may be predicted by similar personality factors, and that chronic procrastination is dysfunctional toward achieving life goals.
