“…The item-total correlations ranged from 0.65 to 0.84, thus also exceeding the usual accepted value of 0.30 41. The value of Cronbach's alpha was higher than 0.74, which was first established for examining the validation of clinical tests,16 and similar to those achieved by the Arabic27 and Hindi25 versions of the ISI (0.92 and 0.91, respectively). However, the item-total correlations of the current research were more stable than those of the Arabic27 and Hindi25 versions (0.49-0.92 and 0.56-0.87, respectively).…”

“…The PSQI is a widely used measure of sleep quality32 and has been used in previous studies as a convergent measure with ISI in other language versions 24,26,27. PSG was used as the primary diagnosis tool for other sleep disorders, and as a complementary instrument for the evaluation of insomnia, although it is not indicated for the routine evaluation of this condition 33,34…”

“…The ISI has been validated for several age groups from adolescence17 to the elderly,18 and is reported to be a useful assessment instrument for individuals with psychiatric diseases,19,20 cancer,21 and other clinical diseases 16,22,23. The ISI has been translated into several languages, including Chinese,24 Hindi,25 Spanish,26 and Arabic,27 with these language versions demonstrating adequate psychometric properties. However, there is no standardization for Korean.…”

Background and PurposeThe purposes of this study were to standardize and validate a Korean version of the Insomnia Severity Index (ISI-K), and to evaluate its clinical usefulness.MethodsWe translated the ISI into Korean and then translated it back into English to check its accuracy. The 614 patients with sleep disorders who were enrolled in this study comprised 169 with primary insomnia, 133 with comorbid insomnia, and 312 with obstructive sleep apnea. All subjects underwent one night of polysomnography (PSG) and completed the Korean versions of both the Pittsburgh Sleep Quality Index (PSQI-K) and the Epworth Sleepiness Scale, as well as the ISI-K. The ISI-K was compared to these sleep scales and various PSG sleep parameters.ResultsThe internal consistency the ISI-K total score was confirmed by a Cronbach's alpha of 0.92, and the item-to-total-score correlations (item-total correlations) ranged from 0.65 to 0.84, suggesting adequate reliability. The correlation between the ISI-K total score and PSQI-K was 0.84, which suggested adequate convergent validity. Low-to-moderate correlations were obtained between the ISI-K total score and PSG-defined sleep parameters: 0.22 for sleep onset latency, 0.38 for wake after sleep onset, and 0.46 for sleep efficiency. A cutoff score of 15.5 on the ISI-K was optimal for discriminating patients with insomnia. The test-retest scores over a 4-week interval with 34 subjects yielded a correlation coefficient of 0.86, suggesting excellent temporal stability.ConclusionsThe findings of this study show that the ISI-K is a reliable and valid instrument for assessing the severity of insomnia in a Korean population.

“…In the current study, we used the ISI to assess the patient's perception of his or her insomnia and the severity of both nighttime and daytime components of insomnia since it has been subject to several validation studies, and its psychometric qualities are highlighted by many publications [14][15][16][17][18][19]. It is available in several languages and is increasingly used as a metric in clinical research.…”

“…Based on a previous literature participants, scoring 10 or more were considered to be insomniacs 16 . Prior research utilized the Arabic version of ISI, which was showed to be reliable with an internal consistency of 0.84 17 . In the current study, ISI was showed to have good reliability with a Cronbach's alpha score of 0.89.…”

Background: Many sedatives and anxiolytics are used in single dose or chronically to aid sleep. Clinically important sedatives include valerian-hops and antihistamines as they are used over the counter and are highly accessible and safe agents. Objectives: To evaluate and compare a single dose of chlorpheniramine versus valerian-hops combination in modulating subjective sleep measures in insomniac war refugees. Methods: Insomnia among refugees was screened using the Insomnia Severity Index (ISI). Insomniac subjects were randomized to received a single dose valerian-hops (320/80 mg) (n = 65), or chlorpheneramine (4 mg) (n = 50) or placebo (n = 76) two hours prior sleeping. Participants were instructed to complete Leeds Sleep Evaluation Questionnaire (LSEQ), visual analogue scales of anxiety and sedation. Also sleep latency, total hours slept and self-rated improvement were obtained. Results: Almost 75% of screened refugees had insomnia. Chlorpheneramine reduced sleep latency and anxiety significantly, however it resulted in poor sleep quality. Valerian-hops group showed marked anxiolysis one hour after dosing, a sleep quality similar to placebo and better than chlorpheneramine, and better alertness compared to placebo. Participants satisfaction was higher with chlorpheneramine and there was no difference in the total hours slept. Discussion: Valerian-hops combination may provide better sleep quality than antihistamines.

Translating the Insomnia Severity Index Into Arabic

Abstract: Preliminary psychometric estimates show that the translated ISI is reliable and valid in this community-dwelling Arabic sample. The translated ISI allows for Arabic researchers to screen for insomnia and plan for future intervention studies.
