Abstract
The purpose of this study is to investigate effects of situational variables on the relationship between leadership behavior and personal power. A questionnairesurvey was conducted for 158 workers at the city office, 425 nurses at the hospital, and 289 workers at the steel company. They rated their own growth need, superior leadership behaviors, and social power (position, power and personal power) of the superior. The results showed that:(1) the leader's task oriented behavior (P behavior) and the human relations oriented behavior (M behavior) were closely related to personal power, but they were not related to position power, (2) the position power moderated the relationship between M behavior and personal power, (3) worker growth need moderated the relationship between planning behavior (one of P behaviors) and personal power, and (4) worker's age moderated the relationship between leadership behavior and personal power, but the direction of effects was found different among organizations.
