Success Factors and Stumbling Blocks in the Cooperation with Child and Adolescent Psychiatry/Psychotherapy from the Perspective of Social Pedagogues In numerous current studies, experts describe a need for improved cooperation between employees of youth welfare and child and adolescent psychiatry/-psychotherapy. The present study investigates how social pedagogues working in youth welfare institutions perceive psychiatrists or psychologists working in child and adolescent psychiatry. Benefits and difficulties of the cooperation are described and potential areas of improvement as perceived by youth welfare employees are identified. The study presents quantitative and qualitative data and pursues a mixed-method approach. The qualitative evaluation is based on the content structuring qualitative content analysis according to Kuckartz (2012) and is complemented by descriptive data. The results are based on the responses of 221 social pedagogues in Switzerland. While 97.7 % of respondents perceive interdisciplinary collaborations for children with high psychological stress as ideal, they also mention various barriers that hinder effective and efficient cooperation. Many social pedagogues wish for the field of child and adolescent psychiatry to show a greater interest in their job profile, as well as more appreciation for the demanding work that they perform. Clarification of roles and responsibilities, a better flow of information and a direct person of contact are also deemed important aspects to improve upon. The study suggests practical approaches for a more effective cooperation.
