This chapter describes the more commonly used subjective assessments to evaluate sleepiness, obstructive sleep apnea (OSA) risk, insomnia presence and severity, and restless legs syndrome (RLS). The chapter also describes measures used to evaluate quality of life in sleep disorders and sleep quality. It explains the most common objective sleep tests including polysomnography (PSG), the multiple sleep latency test (MSLT), the maintenance of wakefulness test (MWT), actigraphy, and the suggested immobilization test (SIT). These tests are typically performed in a sleep laboratory and interpreted by a sleep specialist. The subjective and objective tests should be selected as appropriate for each patient to ensure correct and complete therapy for their sleep disorder. Subjective testing may allow for routine, rapid screening of high-risk populations and repeat evaluation of patient-reported outcomes. Objective testing is more resource and time intensive, but is often necessary for precise diagnosis and treatment.
