This paper reviews the scope of the problem of runaway children and presents treatment approaches currently in use. Several findings on runaway children are discussed: (1) the multiple social and psychological difficulties faced by parents; (2) the high degree of family strain; and (3) the runaways' dissatisfactions with peer and adult interpersonal relationships. The rationale and development of a comprehensive treatment program are described as program components consisting of child management, family enrichment, and interpersonal enrichment in a group work approach. A competency-based training model that facilitates juvenile justice workers' acquisition of skills to deliver this comprehensive treatment program is reviewed, and the evaluation methods to assess the competencies needed to implement the model are presented.
