A study examined the relationship between outdoor leader self-awareness and co-leaders' perceptions of leader influence. Thirty-three challenge course instructors for a major university in the Midwest operated as a peer group, working in instructor teams leading groups in an outdoor setting. Each instructor took a turn as leader of the day. All subjects completed the Personal Orientation Inventory, which measures an outdoor leader's level of self-awareness, and the Rahim Leader Power Inventory, which reveals perceptions of co-leader influence. Results indicate that: perceptions of expert power were directly correlated with inner-directedness; perceptions of expert power were significantly related to age, with older instructors perceived as having stronger expert power bases; as an outdoor leader's age increased, the self-actualizing attribute of inner-directedness also increased; expert power was significantly related to work experience, with co-leaders' perceptions of an outdoor leader's expert power increasing as the leader gained work experience; outdoor leaders saw education as a determining factor influencing co-leaders' perceptions of expert power; and there was no significant difference between men and women in perceptions of power.
