The recording of personality strengths: An analysis of the impact of positive personality features on the long‐term outcome of common mental disorders

Abstract Although personality strengths are assessed frequently in occupational and managerial settings and in children, they have been less used in studies of personality disorder. The aim of this study is to examine the impact of a measure of personality strengths derived from the comprehensive version of the Personality Assessment Schedule (CPAS) (i.e., positive and reinforcing traits) on clinical symptoms and functioning. Eighty‐nine patients with anxiety and depression seen at the 30‐year follow‐up point in a cohort study (Nottingham Study of Neurotic Disorder) were administered the Comprehensive version of the PAS (CPAS). A factor analysis of the results determined the main groupings and their impact on long‐term outcomes as well as their association with change of outcomes over 30 years. Five positive factors (strengths), forceful considerateness, emotional toughness, cautiousness, independence and discernment accounted for 67.2% of the variance using both Varimax and Promax rotations. Low positive scores were strongly associated with suicide attempts, moderate/severe personality disorder, cothymia (mixed anxiety‐depression), greater symptomatology and poor social function. High scores were protective of serious pathology and particularly effective in inhibiting suicidal behaviour. The promotion of personality strengths may be of value in preventing suicidal behaviour and helping pro‐social change in those with personality disturbance.
