PURPOSE: To compare the self-reported estimation of sleep quality evaluated by the Pittsburgh Sleep Quality Index (PSQI) and life quality assessed by the Quality of Life Index (QLI). BACKGROUND: The PSQI comprised 19 questions and assessed a wide variety of factors relating to sleep quality. The QLI consisted of 10 items for self assessment of different dimensions of life quality. SUBJECTS: A representative Austrian sample (n = 1049) aged above 15 years. PROCEDURE: Interviews in the homes of the participants. RESULTS: 32.1% could be classified as poor sleepers (37% females, 26.5% males). Sleep quality decreased with increasing age, especially in women. Overall quality of life was highest in younger (15-29 years) and lowest in elderly subjects (over 50 years). Life quality decreased with increasing age. Between subjective sleep quality and quality of life a moderate, significant correlation was found (r2= 0.6721). CONCLUSIONS: Complaints about a bad quality of sleep could be used as a screening method in the exploration of patients' quality of life (QoL).
