Pittsburgh Sleep Quality Index (PSQI) scoring instructions

SCORING INSTRUCTIONS FOR THE PITTSBURGH SLEEP QUALITY INDEX:
The Pittsburgh Sleep Quality Index (PSQI) contains 19 self-rated questions and 5 questions rated by the bed partner or roommate (if one is available). Only self-rated questions are included in the scoring. The 19 self-rated items are combined to form seven "component" scores, each of which has a range of 0-3 points. In all cases, a score of "0" indicates no difficulty, while a score of "3" indicates severe difficulty. The seven component scores are then added to yield one "global" score, with a range of 0-21 points, "0" indicating no difficulty and "21" indicating severe difficulties in all areas. Scoring proceeds as follows:
Component 1: Subjective sleep quality
Examine question #6, and assign scores as follows:
Response	Component 1 score
"Very good"	0
"Fairly good"	1
