Abstract EN

The study was conducted in order to verify the psychometric properties of Pittsburgh Sleep Quality Index PSQI in a sample of chronic diseases.

The study was conducted on a sample of 348 (79 males, 269 females), (83 pressure patients, 90 diabetes patients, 70 heart disease patients, 105 normals), They ranged from 18 to 86 years old, (M= 38.50, SD= 16.58).

PSQI, a global indicator consisting of seven indicators to assess sleep quality, was translated.

Confirmatory factor analysis of PSQI emphasizes the three dimensions model Vs.

the two dimensions model among samples of pressure patients, diabetes patients, heart disease patients, normal, and among the total sample.

The three dimensions model includes perceived sleep quality ((subjective-sleep quality, sleep latency, use of sleep medications), sleep efficiency (sleep duration, habitual sleep efficiency) and daily sleep disturbance (sleep disturbance, daytime dysfunction during last month).

All goodness of fit indexes appear to be excellent.

Results also show that PSQI has good psychometric properties such as criterion validity with sleep disturbance scale and depressive symptoms scale.

PSQI has good internal consistence and reliability.
