Treatment and study plan

Question-behaviour effect (for affective attitudes)

Behavioral

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 names: Priming

Question-behaviour effect (negatively-worded attitudes)

Behavioral

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).

    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 outcomes

  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))
