Therapeutic Assessment is a model of psychological evaluation that adopts a collaborative approach and a semi-structured systematization to the extent that it has well-defined steps. Considering its intervention nature, Therapeutic Assessment seeks to bring about positive changes in the lives of clients and/or people close to them. The present study aimed to evaluate how the Therapeutic Assessment process presented therapeutic consequences, using the case study as a research method. The description of the results was based on the assistance of a client using the Therapeutic Assessment model. The findings corroborate the hypotheses related to the therapeutic benefits of the Therapeutic Assessment, providing the clients with increased self-knowledge and self-reflection and changes in the way they deal with difficult situations. We conclude that more research on Therapeutic Assessment should be developed to verify other possible benefits of the model.
