The psychotherapeutic utility of the five-factor model of personality: a clinician's experience.

This article summarizes experience using the five-factor model of personality, operationalized by the NEO Personality Inventory (NEO-PI), to facilitate psychotherapy treatment with 119 private-practice, outpatient, psychotherapy patients and their family members over a period of 2 years. Trait theories such as the five-factor model implicitly challenge the premises of much clinical theory, yet they can be useful to clinicians, as they provide a detailed, accurate portrait of the client's needs, feelings, proximate motives, and interpersonal style. I suggest that: Neuroticism (N) influences the intensity and duration of the patient's distress, Extraversion (E) influences the patient's enthusiasm for treatment, Openness (O) influences the patient's reactions to the therapist's interventions, Agreeableness (A) influences the patient's reaction to the person of the therapist, and Conscientiousness (C) influences the patient's willingness to do the work of psychotherapy. Fundamental questions raised by the five-factor model about the nature of psychopathology and psychotherapy are discussed.
