Abstract

Sixty insomniacs, aged 60 years or over, fulfilling the DSM-IV criteria for primary insomnia, completed a set of questionnaires measuring psychological distress. These included the Sleep Impairment Index (SIM), the Symptom Check List 90-Revised (SCL-90-R), the Penn State Worry Questionnaire (PSWQ), the Toronto Alexithymia Scale-20 (TAS-20) and the Elders Life Stress Inventory (ELSI). The insomniacs were compared on these measures with two contrast groups, one of elderly good sleepers and one an elderly community sample. As norms were developed for the SCL-90-R and PSWQ, insomniacs were also contrasted with the norm groups on these measures. In general, the results indicated a higher level of psychological distress among insomniacs than among the good sleepers, while there were negligible differences between insomniacs and the community sample on most measures. Overall, elderly insomniacs scored higher on measures of worry compared with the other groups, followed by measures of somatization, obsessive-compulsion and depression. It is concluded that excessive worrying was the most characteristic feature of elderly insomniacs.
