Limitations and Criticisms of the Existential Approach: A major criticism often aimed at this approach is that it lacks a systematic statement of the principles and practices of psychotherapy. Some therapists who claim adherence to an existential orientation describe their therapeutic style in vague and global terms (such as self-actualization, dialogic encounter, authenticity, and being in the world). The fact that few techniques are generated by this approach makes it essential for practitioners to develop their own innovative procedures or to borrow from other schools of therapy. It must be realized, however, that philosophical insight may not be appropriate for some clients (seriously disturbed or nonverbal clients).
