About this study

The goal of this clinical trial is to investigate the comparison of two incentives to determine their effectiveness for motivating an urban population to participate in a Experience Sampling Method wellbeing studies. It will also investigate alternative incentive preferences that can motivate the population. The main questions it aims to answer are:

  • Does the provision of a financial incentive or social incentive to neighbourhood research participants increase the willingness of individuals to participate in ESM research compared to offering no incentive?
  • What are the reasons for unwillingness to participate in ESM studies?
  • What are the alternative incentive preference that could increase willingness to participate in ESM studies?

Researchers will compare monetary incentive (4 x £100 prize draw qualification) to a non-monetary incentive (invitation to end of project social event to engage research findings) to how they influence willingness to participate compared to offering no incentive.

Participants will:

  • Receive receive an email describing a future experience sampling study in the neighbourhood for at least two times.
  • Complete a survey to indicate their positive or negative interest in the hypothetical study.

Treatment and study plan

No Incentive Email

Behavioral

Participant will receive an email describing a hypothetical experience sampling study that will happen in King's Cross where he or she is an inhabitant as a worker, resident, or visitor. However, this email will not include any promised compensation for future participation in the hypothetical wellbeing study in the neighbourhood. This group serves as the control group to compare the effects of incentives on participation rates.

Financial Incentive Email

Behavioral

Participant will receive an email describing a hypothetical experience sampling study that will happen in King's Cross where he or she is an inhabitant as a worker, resident, or visitor. This email will include a paragraph that describes a compensation for participation in the future study. The type of compensation that will be offered is a financial compensation, which is a chance of enter a prize draw to win a 4 X £100 voucher which can be used to purchase goods and services within the King's Cross neighbourhood in London.

Social Incentive Email

Behavioral

Participant will receive an email describing a hypothetical experience sampling study that will happen in King's Cross where he or she is an inhabitant as a worker, resident, or visitor. This email will include a paragraph that describes a compensation for participation in the future study. The type of compensation that will be offered is a non-financial compensation, which is an invitation to participate in a social event that will be organised by the researchers and the neighbourhood asset manager team at the end of the research project. This event will be exclusive and it will be an opportunity for participants to socialize with other study participants in the neighbourhood. It will also be an opportunity for the study participants to feel they are contributing a change to the neighbourhood and will be able to articulate their views about the wellbeing research findings which is expected to be used to inform future interventions in the neighbourhood.

Primary outcomes

  1. Willingness to participate

    Time frame: From enrollment to the end of treatment at 7 weeks

    Measure the proportion of participants in each arm who agree to participate in the experience sampling study.

Other outcomes

  1. Reasons for non-participation

    Time frame: From enrollment to the end of treatment at 7 weeks

    Participants who are not willing to participate in the future experience sampling study will be asked to indicate four out of seven reasons for the unwillingness.

  2. Alternative Incentive Preferences

    Time frame: From enrollment to the end of treatment at 7 weeks

    Participants who are not willing to participate in the future experience sampling study and who select "inadequate compensation" as one of the reasons for not participating will be asked to select desired incentives from a list of seven options that could motivate a change in participation decision.
