Abstract

In the present article we examine the psychometric characteristics of the Hungarian version of the Groningen Sleep Quality Scale, based on the data of 201 individuals. The reliability and the validity of the scale was tested on two independent samples, composed by a healthy population of 123 university students and a patient population of 78 patients from a psychiatric department, respectively. The reliability of the Groningen Sleep Quality Scale proved to be considerably good, with the Cronbach alpha exceeding the .85 value in the two different samples. We analysed the validity of the scale by contrasting its results with four different questionnaires: the short version of WHO Well-Being Questionnaire - WBI-5, the short version of the Beck Depression Inventory - BDI-R, the Somatic Symptom Scale - PHQ-15 and the Trait Anxiety Scale - STAI-T. The results of the four questionnaires, and the sleep related items of the given questionnaires showed a significant and moderately strong correlation with the results of the Groningen Sleep Quality Questionnaire in both samples. Based on the results of the binary logistic regression analysis, the WHO-5, the PHQ-15, and (at tendency-level) the BDI-R showed a significant effect, by explaining one quarter of the whole variance of the scale. According to the results, the Hungarian version of the Groningen Sleep Quality Scale is sound from psychometric point of view therefore we consider that the scale is a valuable tool for the measurement of subjective sleep quality.
