Brief 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).

Arm Intervention/treatment
No Intervention: Replication group
Replication group - this group will complete the entire questionnaire, in order to replicate the findings of O'Carroll et al (2011)
Active Comparator: Omit affective attitudes
Omitting affective attitudes The intervention is the omission of all questions on affective attitudes. This group will complete a similar questionnaire to the replication group, with the same number of questionnaire items, but affective attitudes will be omitted. Dummy questions (e.g. about politics) will be substituted for these deleted questions.
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).
Other Name: Priming

Active Comparator: Omit negatively-worded items
Omitting negatively-worded affective attitudes. This intervention is the omission of a subset of negatively-worded affective attitudinal items. This group will complete a similar questionnaire to the replication group, with the same number of items, but all negatively-worded affective attitudes will be omitted. Dummy questions (e.g. about politics) will be substituted for these deleted questions.
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).

Primary Outcome Measures :
  1. Intention to become an organ donor [ Time Frame: within 3 months ]
    Mean score of two 7-point items: "I will definitely sign up for organ donation and discuss this with my family in the next few months" and "How strong is your intention to sign up for organ donation and discuss this with my family in the next few months?"


Secondary Outcome Measures :
  1. Taking a donor card after the interview [ Time Frame: Immediately at the end of the interview (i.e. that day, an average of 10-15 minutes after consenting to participate)) ]
    "Did survey participant accept a donor card?" Yes/No
