Objective: To estimate the prevalence rates of, and gender differences in insomnia complaints and its consequences, as well as to assess the reliability and validity of the Insomnia Scale. Method: 2,210 male and female non-clinical Kuwaiti college students participated. Their ages ranged from 16 to 37. Insomnia scale (IS) comprising 12 items was administered in group sessions. Point prevalence rate was computed as the summation of the percentages of responses in the two options “Much” and “Very much” on each item during the most recent month. Results: The IS has acceptable test-retest and alpha reliabilities, and good convergent validity. The prevalence of the 12 IS items ranged from 4.1% to 29% in males, and between 4.8 and 32.2% among females. The highest reported insomnia complaint was early morning awakening in both sexes. It was found that 19.4% of males and 18.1% of females reported difficulty initiating sleep, while 8.6% of males and 15.7% of females reported difficulty maintaining sleep. Females have higher mean scores in 3 items: interrupted sleep, awakening up many times during sleep, and annoyance from interrupted sleep. Conclusion: Point prevalence of insomnia and its consequences among the present sample of Kuwaiti undergraduates lies approximately in the range of previous epidemiological studies. However, the present range is somewhat lower than that of Kuwaiti adolescents. It is useful to administer the same assessment tool in the epidemiology of sleep disorders research.
