How have the outcomes of existential therapy typically been evaluated?

Existential therapy, while rich in philosophical ideas about the human experience, faces unique challenges in terms of empirical evaluation. Historically, it has not lent itself easily to conventional scientific methodologies typically used in psychology. This is due to its focus on subjective experience, personal meaning, and the exploration of existential themes, which are challenging to quantify or measure with standardized testing approaches.

The nature of existential therapy emphasizes individual narratives and the therapeutic relationship, often making it difficult to apply rigorous scientific testing that requires clear, measurable outcomes. This lack of empirical testing can be attributed to both the complexity of existential concepts and the emphasis on a deeply personal therapeutic process that aims to foster growth instead of simply treating symptoms. This means that evaluations often fall short of providing statistically significant results that can be associated with traditional evidence-based approaches, thus leading to a conclusion that the outcomes of existential therapy have not been rigorously tested in the same manner as other therapeutic modalities.

Consequently, while there may be anecdotal and qualitative evidence of its effectiveness, the field has yet to establish a robust body of empirical research that definitively supports the outcomes of existential therapy in a measurable way.
