Distribution of a questionnaire explored the types and determinants of psychotherapeutic intervention with children. The sample consisted of 76 licensed professionals in the fields of psychology, social work, and counseling. Family therapy was the preferred type of psychotherapy; however, psychotherapists employed different therapeutic interventions as the clients age varied. The primary determinant in intervention was the professionals perception of the nature of the child's problem. Developmental knowledge was not considered a significant tool in selecting and implementing therapeutic intervention. Professionals who intervene with children did not believe that their educational programs had prepared them to do so. These results are discussed in terms of the need for specialized training for psychotherapists who intervene with children. / M.S.
