“…The virtues of self-management training were expanded upon by Cooper, Heron, and Heward (1987), who noted: Instances of important behavior change that might have been missed by external agents would not be missed by the individual; certain types of behavior (e.g., smoking, exercise, assertiveness) do not lend themselves to external-agent control but rather are more appropriately monitored by the individual him or herself; those with self-management skills require less trainer time; self-management can be used to control behavior not affected by weak or distant outcomes; some people perform better under self-selected standards; and finally, self-management "feels good." Reactivity, changes in behavior as a result of self-monitoring, is also widely reported (Kirby, Fowler, & Baer, 1991;Mace & West, 1986;McFall, 1977).…”
