This was a three part study designed to evaluate the effectiveness of the Basic Seminar, a five-day personal growth training designed and presented by Lifespring, Inc. The instrument used in this study was the Personal Orientation Inventory (POI) published in 1963 by Everett L. Shostrom and copyrighted by Edits Publishing Co., San Diego, CA. This inventory consists of 150 two-choice comparative value and behavior judgments. Two basic scales measure personal orientation, inner directed support and time competence. Ten subscales measure different conceptually important elements of self-actualizing. The items are scored twice, once for the two basic scales and second for the ten subscales. The human potential movement is a relatively recent phenomenon in contemporary society and Lifespring's Basic Seminar is one of the many personal growth trainings which has developed within this context and is based upon the principles of humanistic psychology. The purpose of the training is to facilitate within the individual self-actualizing processes leading to greater personal fulfillment. The scales in the POI measure those facets of self-actualizing which the Lifespring training is designed to develop and was chosen as the instrument for this study primarily for that reason.
