Abstract
The aims of the present study are to evaluate the impact of insomnia on psychological well-being and to examine the associations of insomnia and psychological well-being with anxiety and depression. Forty-one patients attending our hospital-based Centre for sleep medicine were administered scales for the evaluation of insomnia (ISI), anxiety (STAI-Y), depression (BDI-II) and psychological well-being (PWB). The scores were compared to those of a control group of 68 subjects attending the hospital for routine examinations or as accompanying persons. Significant differences between patients and controls were detected for anxiety and depression, as well as for psychological well-being. Even if subclinical on average, anxiety and depression symptoms were significantly related to poor psychological well-being, whereas insomnia per se was not. These findings suggest that patients with insomnia report a relevant impact on their psychological well-being, and that such an impact seems to be strongly associated with concomitant subthreshold symptoms of anxiety and depression. The implications for diagnosis and treatment are discussed.
