Pre-Sleep InterviewsANS:->>-conducted by sleep technicians who ask questions to clarify information and make careful observations of the patient such as,willingness to learn, mental age, physical limitations, etc. Sleep DiaryANS:->>-Patient keeps a record of sleep habits for 2 weeks
preceding the test. The sleep diary generally has two components: Before Sleep andAfter Sleep. Pre-sleep QuestionnaireANS:->>-standardized form that reviews issues relatedto sleep, but tech asks additional questions for clarification, as needed. The questionnaire determines if the patient's preceding 24 hrs was normal for that individual.

The partner typically is aware of snoring or periods of apnea even though the patient may not be aware. Morning QuestionnaireANS:->>-Takes place in the morning after PSG; May come in the form of a checklist, or the tech may ask specific questions regarding sleep quality,onset to sleep time,number of arousals,TST,Differences between sleeping at home and in lab, and Sleepiness upon awakening.-If pt reports sleep was very differentfrom home, repeat PSG may be warranted. Morning/Evening QuestionnairesANS:->>-asks 19 questionnaires about time preferences to determine if patient is a morning,evening, or neutral person.
