All parameters obtained from the AMOS output with the HBM dimensions: perceived susceptibility (not significant), perceived severity (not significant), perceived benefits, Perceived barriers, cues to action and self-efficacy; β—unstandardised beta co-efficient; Stdβ—standardised beta co-efficient; SE—standard error; 95% CI—95% confidence interval with lower bounds and upper bounds [LCI, UCI]; t—t value, p—shows the significant level.
