CHAPTER 3 72 4) Dirty laundry: A plastic laundry basket filled with items of clothing, underwear, old cleaning cloths and an old oven glove was presented. All items were made to look dirty using coffee. 5) Bedpan: A white plastic bedpan that was made to look dirty with tea and yellow food coloring was presented to the participant. It contained yellow liquid made with food coloring to resemble urine. 6) Lab specimen: A small biohazard zip bag containing the following items was presented to the participant: surgical gloves, oral thermometer, open grimy looking plaster, 2 ml micro-tube containing a drop of hand sanitizer, small piece of ripped rolled-up gauze, and a cotton stick. Data analysis Pre-test differences between conditions were analyzed with one-way ANOVAs and one-way MANOVAs for CFDD, perceived control, and expectations. 2 (Time, pre- test vs. post-test) x 3 (Condition, E+RP vs. E+SB vs. control) mixed MANOVAs, and subsequent 2x3 mixed ANOVAs were used to analyze CFDD and perceived control. Pre-test CFDD ratings (see van den Hout et al., 2011) for the selected contaminant were used as pre-test ratings. Post-test ratings were CFDD ratings for trial 20 before the 30s delay (E+RP and E+SB), or trial 2 (control). Threat belief ratings were analyzed with a 2 (Time, pre-test vs. post-test) x 3 (Condition, E+RP vs. E+SB vs. control) mixed ANOVA. The relationship between pre- to post-test changes in threat beliefs and CFDD ratings was explored with Pearson r correlations. To explore the time course of effects in CFDD in the E+RP and E+SB condition, quadratic trends were analyzed with 21 (Time, pre-test to trial 20) x 2 (Condition, E+RP vs. E+SB) ANOVAs. The immediate effects of wiping (E+SB) and waiting (E+RP) on CFDD were assessed by comparing CFDD ratings at the moment right after touching the contaminant (i.e., before wiping or the 30s delay) and after wiping or the 30s delay. This was analyzed with 19 (Trial, trial 1 to 19) x 2 (Moment, before vs. after wiping or the 30s delay) x 2 (Condition, E+RP vs. E+SB) mixed ANOVAs. Planned comparisons
