Chronic insomnia and depression are often associated. Measuring the impact on quality of life associated with changes in sleep in co-treatment of insomnia and depression requires a valid and reliable patient reported outcome (PRO) instrument. This study aimed to assess the validity of the Sleep Impact Scale (SIS), a sleep-specific PRO instrument, in a population comorbid with Major Depressive Disorder (MDD) and insomnia to support its use in clinical or clinical trial applications.
