ECBI Problem. There was a significant relationship between supports, ตัวแปรร่วม, interaction terms, and confidence and satisfaction (R2= .16, F(11, 117) = 2.073, p < .05). After examining the value of R2, it was determined that 16% of the variance in confidence and satisfaction can be attributed to the ตัวแปรร่วม, independent variables, moderator, and interaction terms.Although the overall model was significant, there were no significant variables or moderators in the final model. ECBI problem was not a moderator of the relationship between the independent variables and confidence and satisfaction.
