大学入学までのスポーツ経験が及ぼす2つの自己効力感と自己愛への影響―構造方程式モデリングによる自己効力感の因果性検討―

The purpose of this study was to investigate whether either generalized self-efficacy or task-specific self-efficacy is an antecedent factor on a structural equation modeling, as well as to verify what influence the number of years being engaged in sports activity before entering college (TEY: Total Experience Years, HSY: High School Years) has on the two types of self-efficacy and self-love. Eight hundred and seventy-eight college students (683 male, 195 female, mean age 18.9 years old) answered a questionnaire consisting of questions regarding the number of years engaged in sporting activity excluding Physical Education class and the number of years engaged in sporting activity in high school. Measurement scales used in the study were the Generalized Self-Efficacy scale (GSE), Exercise Self-Efficacy (Exercise-SE) scale, and Narcissistic Personality Inventory (NPI). Before verifying the accuracy of the hypothetical model, an exploratory factor analysis on NPI extracted five factors consisting of Competence factor, Attention desire factor, Self-reliance factor, Body praise factor, and Leader factor. Consequently, TEY, HSY, Exercise-SE, GSE and five factors of NPI were identified as variables of the hypothetical model. Structure equation modeling verified hypothetical model 1 (GSE→Exercise-SE) and hypothetical model 2 (Exercise-SE→GSE). The result revealed that hypothetical model 1 showed a higher goodness of fit index (CMIN=3.105(p=.875), GFI=.999, AGFI=.995, CFI=1.000, RMSEA=.000) than hypothetical model 2. Hypothetical model 1 demonstrated a direct effect from the TEY and HSY to the GSE. It showed that the number of years engaged in sporting activity affects self-efficacy outside of a sports environment. It also showed that a valid pass exists from GSE to five factors of NPI, implying that GSE could be a promoting factor of NPI.
