Note. SE = Standard Error of B. Model 2 Adjusted R2 = .23, F(9, 81) = 4.05, p < .01.
Step 1 included demographic and personal risk factors predicting the sun protection behavior index score; Step 2 included variables from the Health Belief Model.
Coded as 0 = No, 1 = Yes
Coded as 0 = Low risk, 1= High risk
For every one unit change in the predictors, the sun protection behavior index score changes by the corresponding B.
Step 1 demographic and personal risk factors accounted for a total of 14% of the variance in the outcome of sun protection behaviors while Step 2 Health Belief Model factors accounted for 31% of the variance in the outcome. The additional 17% variance indicated a significant model improvement at p < .01.
