ABSTRACT: BACKGROUND:Thirty years after the origin of the field of psycho-oncology, limited data exist about the work practices of professionals providing psychosocial care to children with cancer and their families. METHOD:A survey was designed to assess training, work environment, theoretical orientation, services provided, subspecialty areas or areas of special interest, satisfactions, challenges, and continuing education needs of pediatric psycho-oncologists. Members of national and international psycho-oncology organizations were invited to participate in the web-based survey. RESULTS:Seven hundred eighty-six professionals from 63 countries responded. The sample consisted mostly of psychologists (41%), physicians (20%), and social workers (14%). Approximately half of the participants worked in a designated psycho-oncology unit. Psychologists and social workers provided the majority of psychosocial services. Individual sessions with parents were most common (42%), followed by sessions with children (41%), survivors (36%), families (31%), and siblings (25%). Therapies provided include cognitive behavioral therapy (50%), relaxation (43%), psychodynamic psychotherapy (27%), play therapy (26%), and imagery (23%). Two-thirds reported having appropriate supervision, 37% were conducting research, and only half felt their salary was appropriate. Differences in therapeutic modalities were found by country. Clinicians desire training on clinical interventions, improving communication with medical staff, research, and ethics. CONCLUSIONS:An international cohort of clinicians providing pediatric psycho-oncology services perform a wide variety of tasks, use a range of therapeutic approaches, and report considerable work satisfaction. Problem areas include professional inter-relations, inadequate supervision, and need for additional specialized training. Opportunity exists for global collaboration in pediatric psycho-oncology research and practices to enhance clinical effectiveness and reduce professional isolation.
