Some studies report that almost half of American workers wish they held different jobs. This paper analyzes the relationships between both the quality and frequency of optimal experience and counselor development. A questionnaire consisting of a 12-item measure of optimal experience, the Supervisee Levels Questionnaire--Revised, and a 1-item measure of flow frequency was administered to 24 counseling practica graduate students. Results supported both research hypotheses: (1) the 12-item measure indicated a positive correlation between the experience of flow and the reported level of counselor development; and (2) the frequency of reported flow experiences while counseling was positively correlated with the level of counselor development. The findings were consistent with both the concept of flow or optimal experience as developed by Csikszentmihalyi and the Integrated Developmental Model of counselor development. The experience of flow and counselor development are complex concepts which appear to be highly correlated. Although with correlation one cannot assign causality, one may speculate that the complex nature of counseling probably provides numerous challenges which make the experience of flow possible. Included here are two scatterplots, which graph the reported optimal experiences, and a copy of the counselor questionnaire. (RJM)
