The aim of this project is to examine the effectiveness of a gamified prosocial VR intervention.
There are two parts in this study. In the first part of the study, participants will be first directed to complete a background survey online (approximately 20 minutes). In the second part of the study, participants will participate in a 5-session gamified training program, one session a week for five consecutive weeks, each session lasts between 10-15 minutes. Upon completion of each session, participants will be required to complete a short 5-minute online survey. A daily diary study will be conducted during the intervention to monitor the nuance behavioral and attitudinal changes.

| Prosocial VR intervention | Behavioral | A five-week gamified prosocial VR intervention program based on literature review and relevance to the local contexts will be developed for the proposed project. The intervention will be expanded to include five weekly sessions, each lasting between 10 to 15 minutes. Each session will depict a different daily life scenario-home, school, street, park, and shopping mall, respectively. During each session, participants will engage in a series of tasks that incorporate elements of prosocial behavior or helping actions within the scene. These tasks are designed to be more comprehensive and interactive, ensuring that participants are fully immersed in the experience for the entire duration of the session. |
| Measure | Description | Time Frame |
|---|---|---|
| Prosocial attitudes | Three items assessing prosocial attitudes will be revised from the Prosocial Orientation Questionnaire. Participants will rate each item on a 6-point Likert scale, ranging from 1 (strongly disagree) to 6 (strongly agree). Higher scores on the scale indicate a greater presence of positive prosocial attitudes. | Baseline (pre-intervention); immediately after the intervention (post-intervention); 1 month after intervention (follow-up) |
| Prosocial identity | The Internalization subscale of the Self Importance of Moral Identity Scale (SIMIS) will be used to measure the construct of prosocial identity. Participants will rate each item on a 7-point Likert scale, ranging from 1 (strongly disagree) to 7 (strongly agree). Elevated scores on the scale indicate a greater degree of prosocial identity. | Baseline (pre-intervention); immediately after the intervention (post-intervention); 1 month after intervention (follow-up) |
| Prosocial intention | The Prosocial Behavioral Intentions Scale (PBIS) will be employed to evaluate individuals' future intentions to engage in prosocial behavior. Participants will rate each item on a 7-point Likert scale, ranging from 1 (Definitely would not do this) to 7 (Definitely would do this). Increased scores on the scale indicate a greater inclination towards prosocial intentions. | Baseline (pre-intervention); immediately after the intervention (post-intervention); 1 month after intervention (follow-up) |
| Attitudes toward helping others | The Attitudes toward Helping Others Scale (AHO) will be employed to assess individuals' attitudes towards helping others. Each item will be rated on a 5-point Likert scale, ranging from 1 (strongly disagree) to 5 (strongly agree). Elevated scores on the scale indicate a greater presence of positive attitudes towards helping others. | Baseline (pre-intervention); immediately after the intervention (post-intervention); 1 month after intervention (follow-up) |
| Measure | Description | Time Frame |
|---|---|---|
| Intervention satisfaction | Intervention satisfaction will be assessed using the Client Satisfaction Questionnaire-8 (CSQ-8). Participants will rate each item on a 4-point Likert scale, with "1" indicating the lowest degree of satisfaction and "4" representing the highest. Elevated scores on the scale reflect greater levels of intervention satisfaction. | immediately after the intervention (post-intervention) |
| Measure | Description | Time Frame |
|---|---|---|
| Socio-demographic variables | The study will collect socio-demographic variables including gender, age, level of education, and family income. | Baseline (pre-intervention) |

| Altruism | Two items from the Preference Survey Module (PSM) will be modified to measure altruism. One example item is as follows: "Imagine the following scenario: you have won 1,000 Euros in a lottery. Considering your present circumstances, how much of the prize would you donate to a charitable cause? (Values between 0 and 1000 are permissible)." Higher scores on this item indicate a higher level of altruistic behavior or tendencies. | Baseline (pre-intervention); immediately after the intervention (post-intervention); 1 month after intervention (follow-up) |
| Empathy | The Single Item Trait Empathy Scale (SITES) will be utilized to assess levels of empathy. Participants will rate this item on a 7-point Likert scale, ranging from 1 (strongly disagree) to 7 (strongly agree), with higher scores indicating a greater degree of empathy. | Baseline (pre-intervention); immediately after the intervention (post-intervention); 1 month after intervention (follow-up) |
| Life satisfaction | The Satisfaction with Life Scale (SWLS) will be employed to evaluate levels of life satisfaction. Participants will rate each item on a 7-point Likert scale, ranging from "Strongly Disagree" to "Strongly Agree." Elevated scores on the scale indicate greater levels of life satisfaction. | Baseline (pre-intervention); immediately after the intervention (post-intervention); 1 month after intervention (follow-up) |
| Subjective happiness | The Subjective Happiness Scale (SHS) will be utilized to assess participants' subjective happiness. Each item will be rated on a 7-point Likert scale. Elevated scores on the scale indicate a greater level of subjective happiness. | Baseline (pre-intervention); immediately after the intervention (post-intervention); 1 month after intervention (follow-up) |
| Affect | The Emmons Mood Indicator will be employed to measure affect, encompassing two dimensions: Positive Affect and Negative Affect. Each item will be rated on a 7-point Likert scale, ranging from 1 (not at all) to 7 (extremely). Elevated scores on the scale indicate a higher level of affect. | Baseline (pre-intervention); immediately after the intervention (post-intervention); 1 month after intervention (follow-up) |
| Gratitude | One item from the Gratitude Adjective Checklist (GAC) will be used to measure participants' gratitude. This item will be rated on a 7-point Likert scale.

| Self-esteem | The Rosenberg Self-esteem Scale (RSE) will be used to measure self-esteem. Each item will be rated on a 4-point Likert scale, ranging from 1 (strongly agree) to 4(strongly disagree). Higher scores indicate higher levels of self esteem. | Baseline (pre-intervention); immediately after the intervention (post-intervention); 1 month after intervention (follow-up) |
| Daily well-being | Daily well-being will be assessed using a single item ("How do you feel right now?") adapted from the Well-Being Manifestations Measure Scale (WBMMS) using a sliding scale ranging from 0 (not good at all) to 100 (very good). A higher score indicates a higher level of daily well-being. | Daily monitoring for 5 weeks during the intervention |
| Daily prosocial act | Daily prosocial act will be measured by one item: "How many acts have you engaged today that involve helping someone else or doing something for a good cause?" Participants will indicate the number of prosocial acts from a drop-down menu ranging from 0 to 10+. The response of "0" will be classified as "no prosocial engagement," and responses of "1" or more will be classified as "having engaged in prosocial acts." | Daily monitoring for 5 weeks during the intervention |
