[i] Notes: n=1,487; *Hierarchical regression involving the entry of predictor variables into the analysis in steps (stepwise). Linear correlation obtained from Spearman (r). ΔR2=the change in R2 value for each subsequent step of the model resulting from the addition of a predictor to the regression equation. β=the beta values in regression are the estimated coefficients of the explanatory variables. A p-value of less than 0.05 was considered to be statistically non-significant.
