Trial summary

The study is conducted to investigate the effects of priming different cultural orientations on participants' decisions on whether to donate their organs, in an opt-out donation system scenario where the default is a presumed consent on the part of the individual. Read more about this study

About this study

Official title: Evaluating Attitudes Towards Organ Donation

The study is conducted to investigate the effects of priming different cultural orientations on participants' decisions on whether to donate their organs, in an opt-out donation system scenario where the default is a presumed consent on the part of the individual.

Read the detailed description

Participants complete a survey where they respond to scales measuring their baseline cultural and power distance orientations, and answer questions on their demographics such as gender, race, employment etc.

24 hours later, participants fill in a 2nd survey where they are instructed to complete 1 out of 2 possible priming tasks. The possible tasks consist of an Individualistic priming condition and a Collectivistic priming condition; both tasks require participants to answer 3 statements each to 3 questions regarding the self or their social group. Participants then indicate their choice on whether to donate their organs (default or opt-out), rate their confidence regarding their choice and complete the same scales measuring their cultural and power distance orientations.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Online Individualistic Prime (statement writing)Behavioural

    Participants write 3 statements each about (1) themselves, (2) why they are not like others, and (3) why it is beneficial to stand out from others

  • Online Collectivistic Prime (statement writing)Behavioural

    Participants think about a social group and write 3 statements each about (1) their social group, (2) why they are like others, and (3) why it is beneficial to blend in with others

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Binary survey item - Decision to Donate Organ

    From a scenario where participants imagine themselves applying for a driver's license in a country where an opt-out organ donation system is enforced, participants are asked to make a binary choice between choosing to donate their organs (default) and choosing not to donate their organs (opt out).

    Measured: 1 minute

  2. Line scale survey item - Confidence in Decision to Donate Organ

    Participants are asked to mark along a line scale on how confident they feel about their decision to donate their organs. The extreme ends of the line scale are defined as "Not Confident At All" (0) and "Extremely Confident" (100).

    Measured: 1 minute

Secondary outcomes (2)
  1. Individual levels of individualism & collectivism

    Individualism and collectivism levels will be measured by Triandis \& Gelfand (1998)'s "Culture Orientation Scale". This is a 16-item scale designed to measure: 1) Vertical Collectivism (VC) - seeing the self as a part of a collective and accepting hierarchy and inequality within that collective; 2) Vertical Individualism (VI) - seeing the self as fully autonomous, but recognizing and accepting the existence of inequality; 3) Horizontal Collectivism (HC) - seeing the self as part of a collective but viewing all the members of that collective as equal counterparts; and 4) Horizontal Individualism (HI) - seeing the self as fully autonomous, and believing in equality amongst individuals.

    All items are answered on a 5-point scale, ranging from 1 = strongly disagree \& 5 = strongly agree. Each dimension's items are summed up separately to create a VC, VI, HC, and HI score to reflect the level of collectivism and individualism in the sampled group.

    Measured: 5 minutes

  2. Individual levels of power distance

    Individualism and collectivism levels will be measured by a 5-item scale used by Hanzaee and Dehkordi (2011) to measure Power Distance, defined as "the extent to which the less powerful members of institutions and organizations within a country expect and accept that power is distributed unequally" (Hofstede and Hofstede, 2005)

    All items are answered on a 5-point scale, ranging from 1 = strongly disagree \& 5 = strongly agree. All items are summed up to create an average score to reflect the level of power distance orientation in the sampled group.

    Measured: 3 minutes

Questions about this trial

What is this clinical trial studying?

A study testing Online Individualistic Prime (statement writing) and Online Collectivistic Prime (statement writing) in people with Individual Difference, run by Yale-NUS College at 1 site in Singapore.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 16 Mar 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Singapore. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Binary survey item - Decision to Donate Organ (time frame: 1 minute). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Mar 2020.
