Table 2.
Differences in mental states between Floatation-REST and Bed-REST.
| Scale [range] | Floatation-REST median [Mean*] (Interquartile) | Bed-REST median [Mean*] (Interquartile) | Wilcoxon test |
|---|---|---|---|
| p | |||
| DIFF SAM-Valence [− 2 …. 2] | 0 [0.30] (1) | 0 [0.12] (2) | 0.339 |
| DIFF SAM-Arousal [1 …. 5] | − 1 [− 0.86] (2) | − 1 [− 0.71] (1) | 0.520 |
| DIFF Anxiety (STAI) [10 …. 80] | − 10 [− 11.66] (11) | − 10 [− 7.94] (14) | 0.033a |
| DIFF Tension (VAS) [0 …. 100] | − 35 (24) | − 20.5 (34) | 0.009a |
| DIFF Stress (VAS) [0 …. 100] | − 30 (27) | − 18.5 (26) | 0.125 |
| Fatigue during REST (VAS) [0 …. 100] | 54 (30) | 65 (35) | 0.010a |
| Mind wandering post- REST (VAS) [0 …. 100] | 33.5 (30) | 31.5 (35) | 0.605 |
Wilcoxon Test for the difference between medians of pre-post measurements of the respective condition (t2–t1 = DIFF) or Wilcoxon Test for post-measurements. Measurements related to the state after Floatation- and Bed-REST. aMeets FDR-adjusted significance of p < 0.05 for 22 statistical tests (Tables 1, 2, 3). * The mean values of a variable are additionally shown when the medians do not exhibit the significant differences between the REST conditions. Next to visual analogue scales (VAS), the Self-Assessment-Manikin (SAM) scales with the subscales valence and arousal as well as the State-Trait-Anxiety Inventory (STAI) were used for the assessment of mental states.
Significant values are in bold.
