Harcourt, L and Kirkby, KC and Daniels, BA and Montgomery, IM, The differential effect of personality on computer-based treatment of agoraphobia, Comprehensive Psychiatry, 39, (5) pp. 303-307. ISSN 0010-440X (1998) [Refereed Article]
The differential effects of the revised NEO Personality Inventory (NEO PI-R) personality factors and intelligence on response to a computerized vicarious exposure treatment for agoraphobia were investigated. The Fear Questionnaire (FQ), the Agoraphobia Cognitions Questionnaire (ACQ), and the Body Sensations Questionnaire (BSQ) were used to assess agoraphobic symptomatology. Fourteen females and four males with agoraphobia diagnoses completed three 45-minute weekly treatment sessions. There was a significant decrease in scores on all three measures following treatment. Compared with published population norms, the agoraphobic subjects showed very high neuroticism, low extroversion, and high openness. Lower agreeableness factor scores predicted good treatment outcome. The NEO PI-R openness factor was negatively correlated with proficiency on the computer program; however, proficiency on the computer program did not correlate with symptom improvement. Overall, these results suggest that personality interacts with treatment at different stages of the therapeutic process.
