Abstract: | Personality measures of Anxiety-Neuroticism, Extraversion and Socialization obtained from self-report questionnaires were studied in a group of sleep-apnea patients (15 males, 5 females), and compared with results from a normal control group (63 males, 21 females) and a group of narcoleptic patients (17 males, 32 females). Sleep-apnea patients were significantly higher in Anxiety-Neuroticism and slightly higher in Extraversion than controls. Although the main symptom, i.e. excessive daytime sleepiness, of sleep-apnea and narcoleptic patients is similar, there were distinct differences in pattern of personality measures. Sleep-apnea patients were lower in Anxiety-Neuroticism and higher in Extraversion. Thus, increased sleepiness alone did not induce uniform changes in personality traits in the two patient groups. It is suggested that the particular personality profile of the sleep-apnea patients is secondary to increased psychosocial strain and coping strategies to keep awake. In contrast, the high Somatic Anxiety scores and low Socialization scores in the narcoleptic group are assumed to reflect a constitutional lability which also involves autonomic and sleep functions. |
