The order of the PSQI items has been modified from the original order in order tofit the first 9 items (which are the only items that contribute to the total score) on a single
page. Item 10, which is the second page of the scale, does not contribute to the PSQIscore.
In scoring the PSQI, seven component scores are derived, each scored 0 (nodifficulty) to 3 (severe difficulty). The component scores are summed to produce a global
score (range 0 to 21). Higher scores indicate worse sleep quality.
