The Sleep Quality Scales are used in the diagnosis of sleep disorders. A proprietary scale can be used to assess sleep quality, but the Pittsburgh Sleep Quality Index (PSQI) is often used.
Sleep Quality Scalesare used in the diagnosis of sleep disorders. In order to assess the quality of sleep, the proprietary Sleep Quality scale can be used. Then, the respondent assesses the truthfulness of the statements concerning various elements of sleep on a specific scale. The sleep quality value is the sum of the points obtained. However, the Pittsburgh Sleep Quality Index (PSQI) is the most commonly used method to measure sleep quality.
Pittsburgh Sleep Quality Questionnaire
The Pittsburgh Sleep Quality Questionnaire examines the 7 components of sleep quality: subjective sleep quality, time taken to fall asleep, sleep duration, sleep efficiency, sleep disturbance, taking sleeping pills and difficulties in functioning during the day.
Measuring the quality of sleep is recommended for people who have sleep problems and also work in shifts (e.g. doctors, nurses).
The Pittsburgh Sleep Quality Questionnaire has several parts. The first contains four questions that cover common sleep habits in the last four weeks. When answering these questions, the subject must enter specific values (minutes, hours) or the frequency of specific problems affecting sleep (number of awakenings at night due to breathing difficulties):
1. What time did you usually go to bed in the evening? 2. How much time would you usually need in the evening to fall asleep? 3. What time do you usually get out of bed in the morning? 4. How many hours did you actually sleep during the night on average (this does not have to correspond to the time spent in bed)
