Abstract
The purpose of this study was to develop an indigenous Sleep Disorders Scale for identifying
the symptoms and prevalence of sleep disorders among Pakistani population. Beginning with
an extensive review of the literature, the symptoms of the sleep disorders were identified.
Interviews with sleep specialists and sleep disorders' patients were also conducted. An initial
pool of items based on the symptoms list obtained from both the sources was generated. Four
focus groups were carried out to identify symptoms and general sleep disturbances. Finally, a
scale consisting of 81 items was developed. Four experts were then asked to examine the
developed scale. Using expert opinion, the items were revised according to their fidelity to the
relevant construct and the scale was finalized. A pilot study was conducted and the Cronbach's
alpha of the scale was highly reliable (α = .94). There is no such scale in use in
Pakistan which identifies the symptoms of all main categories of sleep disorders. This scale
could be used to screen individuals for sleep disorders and treat them timely.
