Abstract:
Objective To develop a self-rating scale of sensitivity of seasickness ( SSSS ) in navy recruits, and also to detect the reliability and validity of the scale. Methods A theoretical model and created entry pool were constructed on the basis of literature review and individual interviews. In the preliminary test, we first investigated 214 naval veterans from the Shantou Coast Guard of the South China Sea Fleet, and then an initial scale was formed following related analysis and exploratory factor analysis. For the large sample test, the initial scale was used to investigate 940 veterans from some of the 3 naval fleets, and then data analysis and exploratory factor analysis were used to form the final formal scale. During the validation test, confirmatory factor analysis and reliability and validity test were performed using the formal scale to investigate 742 recruits from the 3 fleets. Calibration was made by using symptoms and signs of Graybiel motion sickness. In addition, 37 undergraduate students from the Naval Medical Department of the Second Military Medical University of 2016 were tested and a retest was made after a month. Results The formal scale contained 7 factors encompassing 36 items or entries, the cumulative contribution of variance was as high as 72. 031％. The results of confirmatory factor analysis showed that the model fitted well (χ2 =935. 993, df=465,χ2/df=2. 013, GFI=0. 934, AGFI=0. 905, TLI=0. 969, CFI=0. 977, IFI=0. 977 and RMSEA=0. 038). There was a significant positive correlation between the scores of each factor, as well as the scores of each factor and total scores of the scale( r=0. 313-0. 713, P<0. 01;r=0. 529-0. 884, P<0. 01). The total scores and each factor scores of the scale were positively correlated to the scores of the symptoms and signs of Graybiel motion sickness(r=0. 730, P<0. 01;r=0. 365-0699, P<0. 01). The Cronbach'sαof the total scale was 0. 952 and those of various factors were from 0. 797 to 0. 945. The retest reliability of the total scale was 0. 875 and the retest reliability of the 7 factors was from 0. 488 to 0. 837. Conclusion Various indexes of the self-rating scale for the detection of seasickness sensitivity in navy recruits were quite reliable and were suitable for the evaluation of seasickness susceptibility in naval recruits.
