Insomnia Outcomes May Vary by Measurement Method

A recent randomized trial analyzed the daytime effects of suvorexant on older adults (60-85 years) with chronic insomnia, revealing that traditional questionnaires failed to capture significant time-of-day variations in fatigue and cognition. While suvorexant reduced overall insomnia severity, smartphone-based ecological momentary assessment (EMA) identified substantial effects on daytime symptoms that standard measures overlooked, such as greater morning fatigue and decreased alertness in the early day, as well as improved evening functioning. The study highlights the potential of EMA to enhance insomnia treatment evaluation and calls for more comprehensive methods in clinical practice.
