suspect the presence of a learned insomnia component ( see table 2 ).

It is also important to assess for other comorbid sleep and mental health conditions — such as obstructive sleep apnoea ( with the OSA50 screening questionnaire , see figure 2 ), depression and anxiety , which may require treatment — and
Box 2 . Brief questionnaires
• Patients with high levels of daytime sleepiness ( especially sleepiness while driving ) may require referral to a specialist sleep psychologist or sleep physician . The Epworth Sleepiness Scale is an eight-item self-report measure of likelihood of falling asleep in different situations during the day . 33 Patients with excessive daytime sleepiness ( scores greater than 16 )
22 , 29 may have comorbid conditions , such as depression or sleep apnoea .
• The Patient Health Questionnaire-9 ( PHQ-9 ) is a nine-item self-report questionnaire to measure depression . 31 Scores range from 0 to 27 , with higher scores indicating greater depression . A score of 10 or greater indicates at least moderate depression .
• Insomnia and sleep apnoea commonly co-occur and may require referral to a sleep specialist . 29 The OSA50 ( see figure 2 ) is a four-item tool to screen for those at high risk of obstructive sleep apnoea . 30
