A sample of 2,574 volunteer Kuwaiti boys (n = 1,309) and girls (n = 1,265) in secondary schools were recruited. Their ages ranged from 14 to 18 years. 13 items were used to assess prevalence of insomnia, hypersomnia, nightmares, sleepwalking, sleep terror, and narcolepsy. Participants were requested to respond according to the past month on a 5-point scale. The summation of responses in the last two options, i.e., "Much" and "Very much" was considered as the point prevalence rates. Girls had significantly higher mean ratings than boys on the following items: difficulty initiating sleep, fitful and disturbed sleep, waking up several times, nightmares, and sleep terror, while boys had significantly higher mean ratings on sleepwalking and "watching TV causes naps or sleep." The point prevalence on all the items for boys ranged from 4.6% to 35.2%, and that for girls ranged between 1.0% and 37.5%. One should keep in mind that the present sample was not a clinical one.

More than 5,000 passengers on Tokyo subway trains were injured with toxic chemicals including the nerve gas "sarin" on March 20, 1995. The purpose of this study was to identify the effect of sarin exposure on insomnia in a cross-sectional study. A self-administered questionnaire concerning sleep-related items was distributed to victims of sarin exposure in October and November, 2003. Questionnaires were completed by 161 of the 163 participants (98.8%), who were selected from 1,500 subjects. Among them, the authors selected 75 women 30 to 69 years of age. Control participants were collected from inhabitants living in Maebachi City, Gunma Prefecture, Japan. For the younger exposed group (under 50 yr. of age), percentages of poor sleep, difficulty falling asleep, intermittent awakening, early morning awakening, a feeling of light overnight sleep, and insomnia were significantly higher than those for the control group. In contrast, the older exposed group (ages 50 to 69 years) had significantly higher prevalence of poor sleep, a feeling of light overnight sleep, and early morning awakening for the exposed group when compared with the control group. The high prevalence of insomnia and insomnia-related factors for victims especially under 50 years of age suggests a need for research on sleep quality after sarin exposure. Although posttraumatic stress disorder is assumed to be a psychological effect of exposure to a toxic substance, a cause-and-effect relationship has not been established.

An assessment study examining the relationship between sleep quality and personality style in individuals presenting to a sleep clinic with symptoms of insomnia was conducted. The protocol entailed standard clinical interviews conducted by a board certified sleep physician and licensed clinical psychologist. Participants were then assessed using a standard interview and the Millon Clinical Multi-axial Inventory III (MCMI-III) A follow-up appointment was conducted to provide interpretation and treatment recommendations from the interview and testing data. The results from a review of 210 cases are presented in terms of their sleep quality and dominant MCMI-III patterns. Preliminary multivariate analyses indicated two common profiles that correspond to the presentation of insomnia symptomology. These clusters were termed "avoidant" and "anxious" profiles, accordingly. Item content analyses were conducted via the Noteworthy Item classification in the MCMI-III manual to determine the viability of a category determined by the authors called Sleep Behavior Preoccupation. Of this sample 17% fit into the category.

A new scale for the measurement of insomnia, the Bergen Insomnia Scale, was constructed on the basis of current formal and clinical diagnostic criteria for insomnia. There are six items, of which the first three pertain to sleep onset, maintenance, and early morning wakening insomnia, respectively. The last three items refer to not feeling adequately rested, experiencing daytime impairment, and being dissatisfied with current sleep. This scale was validated in three samples, 320 students, 2645 community persons, and 225 patients. Cronbach alphas in the three samples were .79, .87, and .80, respectively. The 2-wk. test-retest reliability for students was .77. In the student and the patient samples, a two-factor solution was found, nocturnal symptoms and daytime symptoms, but in the community sample, a one-factor solution was found. The Bergen Insomnia Scale discriminated well between the patient sample and the other two. In all three, values of convergent and discriminative validity in relation to other self-report measures were good, as well as in relation to polysomnographic data for patients. It is concluded that the Bergen Insomnia Scale has good psychometric properties. It is one of very few insomnia scales which provide normative data for comparisons and which has been validated against subjective as well as polysomnographic data.

This study investigated the prevalence and correlates of insomnia and excessive sleepiness in adults presenting symptoms of obstructive sleep apnea (OSA) in the general population. Randomly selected participants (N = 1,502; 50.7% men, 49.3% women), ages 40 to 70 yr. (M = 53.6, SD = 8.5) were interviewed over the telephone. Insomnia and excessive sleepiness (hypersomnia) were assessed with the Bergen Insomnia Scale and the Epworth Sleepiness Scale, respectively. OSA symptoms were identified by self- or spouse reports on snoring, breathing cessations during sleep, and being tired or sleepy. The prevalence of OSA was 6.2%. Among these participants with OSA, 57.6% reported insomnia and 30.1% reported excessive sleepiness. Furthermore, OSA symptoms were associated with self-reported obesity, hypertension, diabetes, and depression, but only in participants with comorbid insomnia or excessive sleepiness.
