Aim The purpose of this study was to examine the psychometric properties of two brief versions of previously validated cognitive process measures in insomnia: the Anxiety and Preoccupation about Sleep Questionnaire and the Sleep-Associated Monitoring Index. Methods Two samples (168 students and 219 patients with insomnia disorder) completed original and brief versions of the two measures (Anxiety and Preoccupation about Sleep Questionnaire-Brief version and Sleep-Associated Monitoring Index-Brief version). Also, they filled out sociodemographic questions, sleep items, and the Insomnia Severity Index. Results In both samples, the internal consistencies of the two brief versions were acceptable at α = .70 to.72. The correlations between the original and brief versions were significant at .79 to .82. The two brief versions were also significantly associated with insomnia severity and nighttime symptomatology. In the student sample, those with likely insomnia disorder (14.9% of the sample) scored significantly higher on the two brief versions, relative to those without insomnia. Conclusion The two brief versions, Anxiety and Preoccupation about Sleep Questionnaire-Brief version and Sleep-Associated Monitoring Index-Brief version, displayed acceptable psychometric properties. This implies that the two brief versions might be viable alternatives for use in clinical and research settings.

We explored the factor structure and psychometric properties of the Insomnia Severity Index (ISI) using 3 samples totaling 2,066 Mainland Chinese undergraduates. All participants completed the ISI and Sample 2 completed 3 other related measures. Their responses were processed using exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and multiple group analyses. The EFA results revealed a 2-factor structure, whereas the CFA results supported a 3-factor solution, the latter of which was further confirmed by the results of multiple group analyses. The Chinese version of the ISI had a satisfactory Cronbach's alpha coefficient of internal reliability, 2-week test–retest reliability, and criterion validity. Overall, we found that the ISI is a reliable, valid, and psychometrically sound measure of insomnia for use with Mainland Chinese undergraduates.

Insomnia Severity

The COVID-19 outbreak is associated with sleep problems and mental health issues among individuals. Therefore, there is a need to assess sleep efficiency during this tough period. Unfortunately, the commonly used instrument on insomnia severity—the Insomnia Severity Index (ISI)—has never been translated and validated among Bangladeshis. Additionally, the ISI has never been validated during a major protracted disaster (such as the COVID-19 outbreak) when individuals encounter mental health problems. The present study aimed to translate the ISI into Bangla language (ISI-Bangla) and validate its psychometric properties. First, the linguistic validity of the ISI-Bangla was established. Then, 9790 Bangladeshis (mean age = 26.7 years; SD = 8.5; 5489 [56.1%] males) completed the Bangla versions of the following questionnaires: ISI, Fear of COVID-19 Scale (FCV-19S), and Patient Health Questionnaire-9 (PHQ-9). All the participants also answered an item on suicidal ideation. Classical test theory and Rasch analyses were conducted to evaluate the psychometric properties of the ISI-Bangla. Both classical test theory and Rasch analyses support a one-factor structure for the ISI-Bangla. Moreover, no substantial differential item functioning was observed across different subgroups (gender, depression status (determined using PHQ-9), and suicidal ideation). Additionally, concurrent validity of the ISI-Bangla was supported by significant and moderate correlations with FCV-19S and PHQ-9; known-group validity was established by the significant difference of the ISI-Bangla scores between participants who experienced suicidal ideation and those without. The present psychometric validation conducted during the COVID-19 outbreak suggests that the ISI-Bangla is a promising and operationally adequate instrument to assess insomnia in Bangladeshis.

Objectives The study aimed to assess sleep disturbances in patients subjected to home quarantine due to suspected SARS-CoV-2 infection. The study used a mixed methods design study as a research methodology. Methods A semi-structured interview and the scale for Insomnia Severity Index (ISI) were used to achieve the aim of the study. The survey was conducted from 16 to 20 April 2020 and 1 to 2 September 2020 in Poland, at the during of SARS-CoV-2 epidemic in this country. The data were coded and cross-processed. The (COREQ) checklist was followed. Results Interviews with patients and a thorough analysis of recordings revealed commonly used phrases in the following categories: “anxiety”, “ Am I going crazy?”, “Sleep problems”. 10 out of 11 respondents reported sleep disorders of varying severity according to the Insomnia Severity Index scale. Patients presented a fear related to the return to society and normal functioning after quarantine. Additionally, some study participants voiced concerns related to their mental health; some cases of hallucinations were reported. Conclusions Further global population studies should be conducted to analyse this phenomenon. Acute Stress Disorder should be understood as a threat to life and health of an isolated society in quarantine. Further research in this area should be promoted and the need for global guidelines for the entire population should be developed.

The rapid increase in the number of smartphone users has raised concern about the negative psychosocial and physical effects of this use. A descriptive cross-sectional design was conducted to investigate the relationship between smartphone use, anxiety and insomnia among university students. A convenience sample of 404 students from one public university completed questionnaires with items from the Smartphone Addiction Scale, the Depression Anxiety Stress Scale and the Insomnia Severity Index, with some demographic data. High smartphone addition scale score was significantly associated with higher anxiety and stress scores of the Depression Anxiety Stress scale, and higher insomnia severity index score. The findings support the importance of an intervention program to promote appropriate use of smartphones and to improve sleep and psychological symptoms such as stress and anxiety among university students.
