Development of a slovenian version of the pittsburgh sleep quality index (PSQI-SLO) for use with older adults.

ABSTRACT:

Background

Poor sleep quality predicts poor quality of life, poor self-rated health, and chronic diseases and mental disorders among older adults. The Pittsburgh Sleep Quality Index (PSQI) is the most widely used self-report measure of sleep quality in older adults.

Objectives

This study aimed to assess internal reliability, face validity, content validity and internal consistency of the Slovenian version of the PSQI (PSQI-SLO) for sleep quality in older adults.

Methods

A cross-sectional study was used to evaluate content and face validity as well as reliability (ɑ, ω and item-total correlations). Residents of 13 nursing homes and community-dwelling older adults from all regions of Slovenia were sampled. A total of 831 participants aged 65 years and older participated in the study between March and August 2019.

Results

All items were successfully translated to Slovenian. A minor cultural adaptation was made to improve the clarity of the meaning of all items. None of the items had an item content validity index (I-CVI) score lower than 0.50. Kappa indices were excellent for half of the items and good for the remainder. Internal consistency agreed with prior research (ɑ = 0.74). Intraclass correlation coefficient for global PSQI-SLO was 0.62 (p < 0.001). The total score of PSQI-SLO (8.09 ± 3.64 (95%, CI = 7.85-8.34)) was expected and comparable. Fifty-eight and four tenths' per cent (95%, CI = 55%-62%) had at least one chronic disease and 40% (95%, CI = 37%-42%) lived in a nursing home.

Conclusions

PSQI-SLO showed adequate internal consistency and test-retest reliability, and adequate construct and criterion validity. The instrument can be important in assessing older adults' subjective sleep quality in nursing homes, home environment and clinical settings.

Project description:BackgroundSleep disruption is a prevalent symptom reported by survivors of childhood cancer. However, there is no validated instrument for assessing this symptom in this population group. To bridge the literature gap, this study translated and adapted the Pittsburgh Sleep Quality Index (PSQI) for Hong Kong Chinese cancer survivors and examined its psychometric properties and factor structure.MethodsA convenience sample of 402 Hong Kong Chinese childhood cancer survivors aged 6-18 years were asked to complete the Chinese version of the PSQI, Center for Epidemiologic Studies Depression Scale for Children (CES-DC), Fatigue Scale-Child (FS-C)/Fatigue Scale-Adolescent (FS-A), and Pediatric Quality of Life Inventory (PedsQL). To assess known-group validity, 50 pediatric cancer patients and 50 healthy counterparts were recruited. A sample of 40 children were invited to respond by phone to the PSQI 2 weeks later to assess test-retest reliability. A cutoff score for the translated PSQI used with the survivors was determined using receiver operating characteristic analysis.ResultsThe Chinese version of the PSQI had a Cronbach alpha of 0.71, with an intraclass correlation coefficient of 0.90. Childhood cancer survivors showed significantly lower mean PSQI scores than children with cancer, and significantly higher mean scores than healthy counterparts. This reflected that childhood cancer survivors had a better sleep quality than children with cancer, but a poorer sleep quality than healthy counterparts. We observed positive correlations between PSQI and CES-DC scores and between PSQI and FS-A/FS-C scores, but a negative correlation between PSQI and PedsQL scores. The results supported that the Chinese version of the PSQI showed convergent validity. Confirmatory factor analysis showed that the translated PSQI data best fit a three-factor model. The best cutoff score to detect insomnia was 5, with a sensitivity of 0.81 and specificity of 0.70.ConclusionThe Chinese version of the PSQI is a reliable and valid instrument to assess subjective sleep quality among Hong Kong Chinese childhood cancer survivors. The validated PSQI could be used in clinical settings to provide early assessments for sleep disruption. Appropriate interventions can therefore be provided to minimize its associated long-term healthcare cost. Trial registration This study was registered in ClinicalTrials.gov with the reference number NCT03858218.
