Note: Based on 5000 bootstrapping samples; 95% CI = lower and upper level of the bias-corrected confidence intervals for α = 0.05: intervals are significant if they do not contain zero (Preacher and Hayes, 2004). Direct effects (including 95% CIs) are also shown in Fig. 2. FOBT = faecal occult blood test; AR = anticipated regret; ICK = perceived disgust; HLOC = Health Locus of Control.
