Pitsburgh Sleep Quality Index

Form Administration Instructions


The range of values for questions 5 through 10 are all 0 to 3.

Questions 1 through 9 are not allowed to be missing except as noted below.  If these questions are missing then any scores calculated using missing questions are also missing.  Thus it is important to make sure that all questions 1 through 9 have been answered. 

In the event that a range is given for an answer (for example, ‘30 to 60’ is written as the answer to Q2, minutes to fall asleep), split the difference and enter 45.

Scores – reportable in publications


On May 20, 2005, on the instruction of Dr. Daniel J. Buysse, the scoring of the PSQI was changed to set the score for Q5J to 0 if either the comment or the value was missing.  This may reduce the DISTB score by 1 point and the PSQI Total Score by 1 point.

PSQIDURAT              DURATION OF SLEEP
                                    IF Q4 > 7, THEN set value to 0
                                    IF Q4 < 7 and > 6, THEN set value to 1
                                    IF Q4 < 6 and > 5, THEN set value to 2
                                    IF Q4 < 5, THEN set value to 3
Minimum Score = 0 (better); Maximum Score = 3 (worse)

PSQIDISTB                SLEEP DISTURBANCE
                                    IF Q5b + Q5c + Q5d + Q5e + Q5f + Q5g + Q5h + Q5i + Q5j (IF Q5JCOM is null or Q5j is null, set the value of Q5j to 0) = 0, THEN set value to 0

IF Q5b + Q5c + Q5d + Q5e + Q5f + Q5g + Q5h + Q5i + Q5j (IF Q5JCOM is null or Q5j is null, set the value of Q5j to 0) > 1 and < 9, THEN set value to 1

IF Q5b + Q5c + Q5d + Q5e + Q5f + Q5g + Q5h + Q5i + Q5j (IF Q5JCOM is null or Q5j is null, set the value of Q5j to 0) > 9 and < 18, THEN set value to 2

IF Q5b + Q5c + Q5d + Q5e + Q5f + Q5g + Q5h + Q5i + Q5j (IF Q5JCOM is null or Q5j is null, set the value of Q5j to 0) > 18, THEN set value to 3

Minimum Score = 0 (better); Maximum Score = 3 (worse)

PSQILATEN              SLEEP LATENCY
                                    First, recode Q2 into Q2new thusly:
IF Q2 > 0 and < 15, THEN set value of Q2new to 0
IF Q2 > 15 and < 30, THEN set value of Q2new to 1
IF Q2 > 30 and < 60, THEN set value of Q2new to 2
IF Q2 > 60, THEN set value of Q2new to 3
Next
                                    IF Q5a + Q2new = 0, THEN set value to 0
IF Q5a + Q2new > 1 and < 2, THEN set value to 1
IF Q5a + Q2new > 3 and < 4, THEN set value to 2
IF Q5a + Q2new > 5 and < 6, THEN set value to 3

Minimum Score = 0 (better); Maximum Score = 3 (worse)

PSQIDAYDYS                        DAY DYSFUNCTION DUE TO SLEEPINESS
                                    IF Q8 + Q9 = 0, THEN set value to 0
                                    IF Q8 + Q9 > 1 and < 2, THEN set value to 1
                                    IF Q8 + Q9 > 3 and < 4, THEN set value to 2
                                    IF Q8 + Q9 > 5 and < 6, THEN set value to 3
Minimum Score = 0 (better); Maximum Score = 3 (worse)

PSQIHSE                    SLEEP EFFICIENCY
                                    Diffsec = Difference in seconds between day and time of day Q1 and day Q3
                                    Diffhour = Absolute value of diffsec / 3600
                                     newtib =IF diffhour > 24, then newtib = diffhour – 24
                                                 IF diffhour < 24, THEN newtib = diffhour
(NOTE, THE ABOVE JUST CALCULATES THE HOURS BETWEEN GNT (Q1) AND GMT (Q3))
                                    tmphse = (Q4 / newtib) * 100

                                    IF tmphse > 85, THEN set value to 0
                                    IF tmphse < 85 and > 75, THEN set value to 1
                                    IF tmphse < 75 and > 65, THEN set value to 2
                                    IF tmphse < 65, THEN set value to 3
Minimum Score = 0 (better); Maximum Score = 3 (worse)

PSQISLPQUAL                     OVERALL SLEEP QUALITY
                                    Q6
Minimum Score = 0 (better); Maximum Score = 3 (worse)

PSQIMEDS                 NEED MEDS TO SLEEP
                                    Q7
Minimum Score = 0 (better); Maximum Score = 3 (worse)

PSQI                           TOTAL
                                    DURAT + DISTB + LATEN + DAYDYS + HSE + SLPQUAL + MEDS
Minimum Score = 0 (better); Maximum Score = 21 (worse)
Interpretation:              TOTAL < 5 associated with good sleep quality
                                                            TOTAL > 5 associated with poor sleep quality
