The first 18 questions answered by the participant are used in calculating the total PSQI score and component scores. The 18 questions answered by the participant provide information about 7 components: sleep quality (component 1), sleep latency (component 2), sleep duration (component 3), habitual sleep efficiency (component 4), sleep disturbance (component 5), use of sleeping pills (component 6) and daytime sleep dysfunction (component 7). Each component is evaluated on a scale of 0-3 points. The sum of these 7 component scores gives the total PSQI score. The total PSQI score varies between 0-21. The sleep qual
