Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Behavioural expectations will be assessed by a series of 7-point Likert scale items (with response options ranging from strongly disagree to strongly agree) administered via computer-based survey immediately post-intervention. Likert scales will measure the extent to which participants agree with statements pertaining to their perceived likelihood of engaging in each of the following behaviours: 1. Adherence: 1.1. Remaining in place until the arrival of a shower 1.2. Disrobing 1.3. Undergoing dry decontamination 2. Alternative courses of action: 2.1. Going to a hospital without following any of the police officer's instructions 2.2. Leaving the area without following any of the police officer's instructions 2.3. Seeking further information before taking any action For each of the above behaviours, there will be three items pertaining to the extent to which people: would be likely to; would try; or would want to engage in each behaviour. Scores for all three items will be summed to provide an overall behavioural expectation score for each behaviour. Measured immediately post-intervention. | — |
