Intervention

Behavioral:
• Question-behaviour effect (for affective attitudes)
Investigators propose to investigate the Question-behaviour effect (omit affective attitudes). Investigators will conduct an experimental manipulation by omitting certain items from a questionnaire assessing attitudes to organ donation. Specifically, investigators will omit questions on affective attitudes. This group will complete a similar questionnaire to the comparison group, with the same number of items, but items on affective attitudes will substituted for non-affective items (e.g. on political parties).
• Question-behaviour effect (negatively-worded attitudes)
Behavioral: Question-behaviour effect (for negatively-worded attitudes) Investigators propose to investigate the Question-behaviour effect (omit negatively-worded affective attitudes). Investigators will conduct an experimental manipulation by omitting certain items from a questionnaire assessing attitudes to organ donation. Specifically, investigators will omit questions on negatively-worded affective attitudes. This group will complete a similar questionnaire to the comparison group, with the same number of items, but items on negatively-worded affective attitudes will substituted for non-affective items (e.g. on political parties).
