Validation of the adapted Leeds sleep evaluation questionnaire in Ethiopian university students

Abstract: BackgroundCurrent evidence supports the applicability of the Leeds Sleep Evaluation Questionnaire (LSEQ) in screening for insomnia. The psychometric properties of the LSEQ have never been investigated in an African population. Therefore, this study aimed to validate the adapted version of the LSEQ-Mizan (LSEQ-M) in Ethiopian university students.MethodsOf a preliminary sample of 750 (random sampling), 424 students (age = 21.87 ± 4.13 years and body mass index = 20.84 ± 3.18 kg/m2) from Mizan-Tepi University, Mi… Show more

“…Table 2 shows the item analysis of the SDS-Khat in polysubstance users. A minimum of 15% response rate of the highest or the lowest score was used to describe the presence of the ceiling or the floor effect, respectively [ 14 , 18 , 28 ]. There was no ceiling and floor effect in the SDS total score with a range of 2–13 in the study population.…”

“…Insomnia patients usually have increased levels of daytime sleepiness; therefore, the higher values for the ESS item as well as the ESS total score establish the validity of the scale in Ethiopian university students [1]. In comparison with other sleep questionnaires validated among Ethiopians, the ESS is on par with the Leeds sleep evaluation questionnaire and slightly better than the Pittsburgh sleep quality index [17, 18]. For the Leeds sleep evaluation questionnaire, all item scores, as well as the total scores, differed significantly among known-groups, while for the Pittsburgh sleep quality index, two item scores did not differ among known groups [17, 18].…”

“…The participants were interviewed by an experienced sleep researcher blinded to their ESS scores to screen for the presence of the symptoms of insomnia. Insomnia was defined according to criteria listed in the International Classification of Sleep Disorders (ICSD-2) [1, 17, 18]. The diagnosis was based on (i) reporting insufficient sleep occurring almost nightly, (ii) complaints of restlessness after sleep, (iii) mild to moderate levels of socio-occupational impairment, (iv) complaints of problems such as anxiety, daytime fatigue, irritability, and tiredness.…”

“…In addition to the physical measurements we will also administer questionnaires at baseline and follow-up, to assess the effect of the screen media use restriction on different psychological and physical constructs. The adults will answer the following questionnaires; WHO-5, Profile of Moods Scale [40] and two components of the Leeds sleep evaluation questionnaire [41]. On behalf of the participating children, the adults will answer the Strength and Difficulties Questionnaire [42].…”
