Summary of state-dependent measures.
| Measure | Factor | Habitual | Curtailed | p-Value | q-Value |
|---|---|---|---|---|---|
| Hunger | Hunger (100 mm VAS) | 67.1 ± 10.24 | 65.5 ± 10.3 | 0.916 | 0.916 |
| G-FCQ-S (0–15 per factor) | Total | 44.2 ± 9.7 | 46.2 ± 12.3 | 0.429 | 0.687 |
| F1-Desire to Eat | 6.1 ± 2.0 | 6.1 ± 2.2 | 0.948 | 0.916 | |
| F2-Anticipation to positive reinforcement | 8.9 ± 2.0 | 9.5 ± 2.7 | 0.232 | 0.618 | |
| F3-Anticipation to negative reinforcement | 11.2 ± 1.8 | 11.1 ± 2.6 | 0.859 | 0.916 | |
| F4-Obsessive preoccupation | 6.6 ± 2.4 | 7.4 ± 3.0 | 0.124 | 0.496 | |
| F5-Craving as a physiological state | 9.1 ± 2.0 | 9.4 ± 2.7 | 0.405 | 0.687 | |
| PANAS | Positive Affect | 23.6 ± 2.0 | 17.6 ± 6.4 | <0.001 | <0.001 |
| Negative Affect | 12.8 ± 3.9 | 13.2 ± 4.3 | 0.539 | 0.719 |
Positive affect was significantly decreased after sleep curtailment, whereas, hunger, food craving, and negative affect were not. Larger numbers indicate a greater response. For example, positive affect is higher after a habitual night compared to a curtailed night. FDR correction, shown as q-values, did not change the significance of any comparisons.
