METHODS: A comparative multiple case study with an experimental and control condition, applying deductive analyses of diagnoses and treatment plans.
RESULTS: The analyses revealed that the number of diagnostic statements and planned treatment actions in the experimental group was significantly larger and more differentiated than in the control condition. In the control group, consequential harm and protective factors were hardly mentioned in diagnoses and treatment plans.
CONCLUSIONS: Working with the \'Diagnostic Guideline for Anxiety and CB\' leads to improved diagnoses and treatment plans compared with care as usual.
