Variance and intraclass correlation coefficients for sleep variables.
| Data Type | Between Person Variance (Intercept) | Within Person Variance (Residual) | Total Variance | ICC | |
|---|---|---|---|---|---|
| TST | Subjective | 2289 | 5663 | 7952 | 0.2879 |
| Actigraphy | 1118 | 4215 | 5333 | 0.2096 | |
| SOL | Subjective | 881.2 | 2474 | 3355 | 0.2627 |
| Actigraphy | 308.7 | 1012 | 1321 | 0.2337 | |
| MI | - | 0.015 | 0.018 | 0.033 | 0.4592 |
| SOLd | - | 445.6 | 2166 | 2611 | 0.1707 |
TST = total sleep time, SOL = sleep onset latency, SE = sleep efficiency, MI = misperception index, SOLd = sleep onset latency discrepancy, ICC = intraclass correlation coefficient. TST and SOL were measured in minutes.
