Dear Diksha Sapkota!

With my pleasure.

Please, open an Attachment.

Hello Diksha, I checked original article that mentioned the GSDS-reference provided below. It seems like the GSDS contains 21 items rating the frequency of specific sleep problems during the past month from 0 (not at all, scores as 0) to 7 (every day, scores as 7). Scores are summed to produce a score between zero and 147. Higher score is suggestive of greater sleep disturbance.

The 21 items related to frequency in the past month of:

· difficulty getting to sleep (one item), score range 0 to 7

· waking up during sleep (one item), score range 0 to 7

· waking up too early from sleep (one item), score range 0 to 7

· quality of sleep (three items: sleeping poorly, not feeling rested upon awakening, and not feeling satisfied with sleep), 3 x (0-7), score range 0 to 21

· quantity of sleep (two items: too little sleep and too much sleep), 2 x (0-7), score range 0 to 14

· fatigue and alertness at work (seven items), 7 x (0-7), score range 0 to 49

· and use of substances to help induce sleep (six items, ranging from aspirin to prescription drugs), 6x (0-7), score range 0 to 42.

Hope this helps.

Best wishes,

Tatyana
