RESUMO
Objective: Untreated school refusal increases the risk of a premature discontinuation of the educational career. The aim of this study is the economic evaluation of a manual-based treatment for school refusal in comparison to the standard treatment. Method: Within the cost-minimisation analysis, resource use is measured retrospectively for six months using the CSSRI questionnaire. Unit costs for most health care services are derived from published standard prices. Costs are calculated from the societal perspective based on prices compiled in 2011. The cost comparison during the one-year intervention period applies a difference in differences Approach. Results: The most common diagnoses among the 112 participants are phobic and emotional disorders. The average cost per patient during the intervention period amounts to 7197 (95 %-CI: 4746 10 079 ) for the manual group and 9294 (95 %-CI: 6313 12 878 ) for the control group. The difference in adjusted costs of 1453 in favour of the manual group is not statistically relevant. Conclusions: The manual-based treatment is equivalent if not slightly advantageous compared to the standard treatment considering the clinical outcomes and cost of illness.
