Fostering Prosocial Preventive Behaviours Through Awe

The goal of this randomized control trial is to investigate the impact pf awe on prosocial preventive behaviours against infectious diseases among adults from Hong Kong, Singapore, and ten major cities in Mainland China (Beijing, Shanghai, Guangzhou, Shenzhen, Hangzhou, Chongqing, Chengdu, Wuhan, Xi'an, Nanjing). The main questions it aims to answer are:

* Does experiencing awe increase adults' intentions to engage in prosocial preventive behaviours against infectious diseases, including vaccination, mask wearing, and social distancing? * Does the impact vary across three research sites?

About this study

This study will be conducted as a nested sub-study within a main longitudinal study implemented online. The baseline assessment of the longitudinal study was conducted between October and November 2025. Participants who agreed to be recontacted will be invited to join the randomized controlled trial (RCT) approximately four months after the baseline assessment, in February-March 2026. At that time, participants will be randomized in a 1:1 ratio into either the intervention or control group.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Adults (age ≥18 years) who live in
  • Hong Kong, Singapore, and ten major cities in Mainland China (Beijing, Shanghai, Guangzhou, Shenzhen, Hangzhou, Chongqing, Chengdu, Wuhan, Xi'an, Nanjing) over the past one year
  • Able to read and understand written Chinese or English
  • Have access to the internet through computers, mobile phones, or tablets

Exclusion criteria

  • Individuals with cognitive or linguistic difficulties that would prevent them from completing an online survey will be excluded.

Treatment and study plan

Awe intervention

Behavioral

The intervention is a three-step mini game named Hidden Picture Puzzle designed to induce the feeling of awe. In the game, participants will first see a picture of nature covered by six opaque blocks. They will be asked to guess the content of the picture. After making their choice, participants will be instructed to click the six blocks to gradually uncover the picture. Once all six blocks are removed, the full image will be revealed. In the final step, participants will be instructed to imagine themselves in the scene and describe their feelings by selecting the word from a provided list. To ensure that participants will have sufficient time to complete the imagination tasks, they will be required to pause for at least 15s before proceeding to indicate their immediate feeling. Each participant will complete four rounds of this mini game, each with a different picture.

Neutral imagination

Behavioral

For the control group, the mini game Hidden Picture Puzzle will also follow a three-step format, identical in structure to the intervention condition. However, the images provided will depict everyday objects (e.g., a bottle) rather than nature scenes. Similarly, when participants are asked to guess the content of the picture. After the participants finish uncovering the pictures, they will be asked to imagine their interaction with these daily objects and describe the features of the objects by selecting a word from a provided list. As in the intervention group, participants in the control group will complete four rounds of the mini game, each with a different image.

Primary outcomes

  1. Intentions to participate in future preventive behaviours

    Time frame: Immediately after they complete the game with manipulation

    Participants will be asked about their intentions to participate in future vaccination, mask wearing, and social distancing during next winter influenza season using a 7-point Likert scale (1=Never, 7=Certain).

  2. Behavioural choices in the pandemic vignettes

    Time frame: Immediately after they complete the game with manipulation

    Based on a hypothetical infectious disease pandemic, six vignettes will be shown to the participants, comprising three on vaccination and three on social distancing. Each vignette illustrates a trade-off between personal cost and social benefit in engaging in these prosocial behaviours. Participants will be asked to report how likely will they are to engage in the prosocial preventive behaviours using a 7-point Likert scale (1=Never, 7=Certain).

Secondary outcomes

  1. Intentions to engage in social activities

    Time frame: Immediately after they complete the game with manipulation

    Participants will also be asked their intentions to engage in social activities using a 5-point Likert scale (1=Very unwilling, 5=Very willing).
