Do existential therapy approaches produce measurable clinical benefit, or does the evidence differ sharply by which existential tradition is being tested?

Existential therapies have shown varying efficacy in adults, with meaning-centered therapies improving life meaning and moderately reducing psychopathology, supportive-expressive therapy showing small benefits for psychopathology, and experiential-existential and cognitive-existential therapies showing no significant effects; despite limited and low-quality evidence, structured interventions incorporating psychoeducation, exercises, and discussion of meaning appear most promising.
