Self-actualization in a marathon growth group: Do the strong get stronger?

Examined the effects of a weekend marathon on the level of self-actualization of 20 male and 8 female college students 1 and 4 wks after their group experience. The relationship between ego strength and extent of change in self-actualization during a marathon was also studied. Comparison of pre- and posttest scores on the Personal Orientation Inventory and Barron Ego-Strength scale indicate that, in general, the group experience did increase self-actualization and the effects persisted through the 4th wk afterward. The possibility of a sleeper effect is discussed, and hypotheses are offered regarding conditions necessary for such groups to be effective. Ss' initial level of ego strength was unrelated to changes in self-actualization. (29 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)
