Adjusted R square, adjusted multiple determination coefficient; B, unstandardized regression coefficient; Beta, standardized regression coefficient; F (df 1, df 2), coefficient of analysis of variance (degrees of freedom 1, and 2); p-level, level of significance of the Beta coefficients; R, multiple correlation coefficient; R square, multiple determination coefficient; Sig. F, level of significance of the F coefficient.
