Personality, body weight and ultimate outcome in anorexia nervosa.
The Eysenck Personality Inventory, a highly standardized self-rating questionnaire, allows 2 measures of psychosocial functioning on independent scales entitled "emotionally" and "extroversion/introversion." A population of severely ill, low body weight anorectics revealed a high degree of "introversion" and variable amounts of "emotionality" on these measures. Low amounts of "emotionality" were associated with abnormally high "lie" scores. Following restoration of body weight to full matched population mean levels within an intensive treatment program, significant changes occurred on these measures--increased extroversion scores, decreased emotionality and lie scores. However, possibly qualitative changes had occurred in the state of emotionality since high levels were now related to good clinical outcome many years later. The nature of this phenomenon is discussed.
