Planned outcome assessments include app feasibility and acceptability, sleep duration, regularity, and quality, presenteeism, absenteeism, performance, mood, adverse outcomes, and healthcare utilization assessed monthly and at granular daily intervals.
What was found
No empirical results or numbers are reported. The abstract only describes the rationale, study design, and planned outcome measures.
Why it matters
