Table 2: Questionnaire items of the Self-Consciousness Scale (SCS), identified factors, and their loadings. The items that had higher loadings on Factors 1, 4, and 5 were related to public self-consciousness, as defined by [PERSON] (1984) [21]. The items with particularly high factor loadings for Factor 1 were items 6, 8, 9, 10, and 21 (more than the absolute value of 0.40). We named this \"concern about the self observed by others\". The items with particularly high factor loadings for Factor 4 were items 18 and 21. Notably, some items (items 6, 8, and 10) showed higher loadings on Factor 1, while they showed lower loadings on Factor 4. When considering contents of these items, Factor 1 represents concern about the observable (overt) aspect of the self which could be observed by others, while Factor 4 represents concern about evaluation of oneself by others. Thus, Factor 4 is qualitatively different from Factor 1. Therefore, we named Factor 4 \"concern about being evaluated by others\". Lastly, the items with particularly high factor loadings for Factor 5 were items 6 and 16. We named this \"concern about one's own appearance\".
