Registered outcomes 4
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description | Source |
|---|---|---|---|---|
| Primary | Composite Objective Sleep Quality Index Derived From Wearable Device | During 5 consecutive days around baseline assessment | A composite objective sleep quality index will be derived from wearable device data collected continuously over five consecutive days. The composite score will be calculated by combining standardized values of total sleep time, sleep efficiency, sleep onset latency, and wake after sleep onset into a single summary measure representing overall objective sleep quality. | ClinicalTrials.gov |
| Secondary | Sleep Quality (Pittsburgh Sleep Quality Index Scores) | Baseline (single assessment) | Subjective sleep quality will be assessed using the Pittsburgh Sleep Quality Index (PSQI). The total PSQI score ranges from 0 to 21, with higher scores indicating poorer sleep quality. | ClinicalTrials.gov |
| Secondary | Cognitive Performance (Victoria Stroop Test Scores) | Baseline (single assessment) | Attention and executive functions will be assessed using the Victoria Stroop Test. Outcome measures include completion time and error scores obtained during the test. | ClinicalTrials.gov |
| Secondary | Verbal Memory Performance (Öktem Verbal Memory Processes Test Scores) | Baseline (single assessment) | Verbal memory will be evaluated using the Öktem Verbal Memory Processes Test. Outcome measures include standardized scores reflecting learning and recall performance. | ClinicalTrials.gov |
