The DSM-5 Level 2—Sleep Disturbance—Adult measure is the 8-item PROMIS Sleep Disturbance Short Form that assesses the pure domain of sleep disturbance in individuals age 18 and older. The measure is completed by the individual prior to a visit with the clinician. If the individual receiving care is of impaired capacity and unable to complete the form (e.g., an individual with dementia), a knowledgeable informant may complete the measure as done in the DSM-5 Field Trials.
However, the PROMIS Sleep Disturbance Short Form has not been validated as an informant report scale by the PROMIS group. Each item
asks the patient (or informant) to rate the severity of the patient’s sleep disturbance during the past 7 days.
