Zusammenfassung: | The objectives of this study were to validate the Patient Empowerment Strategies Questionnaire (PES-Q) in a Greek sample and to study its psychometric properties in a sample of patients diagnosed with chronic insomnia.
This is a validation of the PES-Q in Attikon General Hospital, School of Medicine, National and Kapodistrian University of Athens. The questionnaire was administered to 93 subjects aged between 18 and 85 years (mean age ± SD: 54.7 ± 15.2, 28% males).
The criterion validity of the questionnaire was tested with the use of four specific criteria: the Athens Insomnia Scale, the Pittsburg questionnaire (Pittsburg Sleep Quality Index), the Depression, Anxiety and Stress Scale, and the Self-Esteem Scale.
According to factor analysis results, the structure of the original scale was confirmed by the presence of one main factor in the Greek sample, explaining 40.1% of the variance of PES-Q queries. The questionnaire showed satisfactory reliability (Cronbach's α = 0.887). The results of the current study suggest that the PES-Q may be used as an accurate psychometric instrument for the purposes of chronic insomnia. Future research should examine the psychometric qualities of the PES-Q Greek version in a larger sample. |
