Table 2.
Means, standard deviation and correlations for reported sleep duration and estimates based on broken stick model.
| N | M(SD) sleep duration | M(SD) sleep duration estimated by broken stick model | Correlation (p) | |
|---|---|---|---|---|
| 1 month | 96 | 15:28 (3:13) | 15:20 (2:46) | .78 (<.001) |
| 3 months | 94 | 13:47 (2:39) | 13:53 (2:02) | .98 (<.001) |
| 6 months | 103 | 13:06 (2:16) | 13:12 (1:42) | .96 (<.001) |
| 9 months | 72 | 12:26 (2:08) | 12:19 (1:32) | .95 (<.001) |
| 12 months | 87 | 12:49 (1:54) | 12:40 (1:25) | .92 (<.001) |
Note. M and SD reported in hours:minutes. N for broken stick estimates is always N = 112 since missing data is imputed. Ns for reported sleep durations and correlations are reported in the table.
