| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Replication group | No Intervention | Replication group - this group will complete the entire questionnaire, in order to replicate the findings of O'Carroll et al (2011) | |
| Omit affective attitudes | Active Comparator | 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. |
|
| Omit negatively-worded items | Active Comparator | 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. |

| 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). |
| Measure | Description | Time Frame |
|---|---|---|
| Intention to become an organ donor | 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?" | within 3 months |
| Measure | Description | Time Frame |
|---|---|---|
| Taking a donor card after the interview | "Did survey participant accept a donor card?" Yes/No | Immediately at the end of the interview (i.e. that day, an average of 10-15 minutes after consenting to participate)) |
