Jungian theory was used as a way of understanding human behavior and personality development and of enlarging the knowledge base for social work practice. The primary purposes of this exploratory multi-case study were: (1) to identify resources and methods which clinicians may use for promoting personality-spiritual development; and (2) to clarify and expand the profession's knowledge and understanding of spirituality and the transpersonal dimension of the person. The research participants, recovering alcoholic adult children of alcoholics, were assigned to one of two groups based on level of self-actualization (ten self-actualized; seven not-self-actualized) as determined by the Personal Orientation Inventory. Data collection included intensive interviews using Fowler's Faith Development Interview Instrument and the Recovery Interview Guide and the administration of several questionnaires: Clinical Measurement Package Index of Peer Relationships, Symptom Check List-90-Revised, and Problem Check List. A quantitative approach was used to identify the number of resources and methods which recovering alcoholic ACOAs used in their recovery and to relate level of spiritual development with current life functioning which included length of sobriety, faith stage, symptomatology, and problems in daily living. Qualitative methods addressed the types of resources and methods used in the recovery process as well as the respondents' views of spirituality and creativity. Respondents identified specific resources and methods as being particularly helpful. Positive relationships were found between level of self-actualization and most indicators of current life functioning, however, a negative relationship was found between level of self-actualization and length of sobriety. Different definitions of spirituality were made explicit, and a sketch of a new model which offers a broader view of the person was presented as a way of extending the current thinking about spirituality and a person's spiritual development. Implications of the findings for clinicians, researchers, and theoreticians were discussed.
