Accurate prediction of space motion sickness is dependent, in part, upon the reliability of terrestrial-based motion sickness susceptibility tests. In the present study, test-retest reliability values were derived from motion sickness susceptibility scores obtained from two successive exposures to each of three tests: 1) Coriolis Sickness Sensitivity Index (CSSI); 2) Staircase Velocity Movement Test (SVMT); and 3) Parabolic Flight Static Chair Test (PSCT). The reliability of the three tests ranged from 0.70 to 0.88. Normalizing values from predictors with skewed distributions improved the reliability. The apparent inconsistency between our finding of high reliability of predictive tests, and previous reports of low correlations between ground-based predictors and space motion sickness may be due to unreliability in assessment of the sickness criterion. Issues of reliability and validity of predictor and criterion measures, and their implications for future development of ground-based predictive tests are discussed in some detail. |
