Summary

The investigators aim to experimentally manipulate presence of questions on positive or negative affective attitudes to see if including these moderate as intention to become an organ donor. The methodology will be replicated across three international sites (RCSI Dublin, RCSI Bahrain, RCSI Perdana University).

Conditions

• Organ Donation

Interventions

Type	Name	Description
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).
BEHAVIORAL	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).
