How Does Group Data Collection Work?
For experience sampling and ecological momentary assessment projects, the default is to collect data at the individual level. In other words, we care only about individual experiences.
However, there are many instances when one is interested in collecting data from groups of individuals to understand their collective experience.
Group data collection is useful when you are interested in:
- Romantic relationships
- Workplace relationships
- Team dynamics
Setting up Group Data Collection
For Premium licenses, you will have the option of going into the Project Design tab as shown below.
By default, the data collection will be at the individual. You can toggle 'Group' to collect group data.
Number of Members per Group
When you toggle on the Group Data Collection you can specify the number of members there are in the group. For example, if you are interested in collecting couple or dyadic data, you will specify "2"; if you are interested in teams of 5 people, you will specify "5".
Setting up the number of individuals will automatically ensure that people who join your ExpiWell projects will need to reach the specified number of members to be able to start the project. For example, if you specify "3" members in each group, the project will not begin for the first two participants until the final group member joins.
In addition, once the number of members in the group reaches the specified number, no more new members can join the same group.
You will need to provide a group access code to participants so they can enter it after joining the project. You can create a unique group access code of up to 8-character alphanumeric (ignoring upper and lower case) for each group of participants. This will help ExpiWell differentiate the groups and track the number of participants in each group. In addition, when you download the data, you will be able to see the group access codes so you know which participant belongs in which group.
Synchronize notification timings / Yoking
Toggling the "synchronize notification timings" or "yoking of timings" ensures that all the scheduled notifications and surveys will occur at the same time for ALL participants in the group. For example, if you have a survey that is scheduled to start randomly from 9am to 12pm, ALL participants will receive the survey and notification at the same "random" time, such as 10:17am EST.
Otherwise, the scheduled notifications and surveys will occur at each participants time. For example, if you have a survey that is scheduled to start randomly from 9am to 12pm, Participant 1 may receive it at 9:12 EST, another participant may receive it at 11:21 EST.
participants will need to be in the same time zone to start the project. Otherwise, they will not be able to start the project even if the number of participants reaches the specified number. This is because synchronization requires group members to be in the same time zone.
Participant Process in the Mobile App
After participants enter the access code, they will be asked to enter the “Synchronization Code.”
The project will only start after the system receives the codes that are equal to the number of members within the group (e.g., 2).
For members waiting for other members to enter the group code, they will see this message.
“Thank you. We are waiting for all other members of your group to join before the project begins.”
If all participants have entered the group code and are in the same time zone, then the project will start, and they will receive this notification.
“All members in your group have joined, and your project [NAME] has started.”
If the 'Synchronize notification timings' are enabled, participants have to be in the same time zone; otherwise, the project will not start. They will see this message.
“The project requires synchronization of notification timings. The current group has members in different time zones, so the project cannot continue.”
Researchers are able to track the group access code of each group, all the participants who joined the project, and if the project has already started.
Yoking in EMA and ESM, particularly in ExpiWell, is an innovative approach to understanding the dynamics of dyads and groups, such as couples, teams, or work relationships. This method ensures that notifications and surveys are synchronized, allowing for the simultaneous collection of data from all group members.
This synchronization is vital for researchers focusing on interactions and shared experiences within dyads or groups, providing insights that individual data collection cannot offer. Whether exploring couple dynamics or team behaviors, the yoking feature in EMA and ESM studies adds depth and precision to the research, enabling a more comprehensive understanding of collective experiences.
Moreover, this approach enriches the data with contextual depth, as responses are gathered in a unified timeframe, reflecting the real-time interplay of group dynamics. This capability is particularly beneficial for studies that capture the nuances of interpersonal relationships and group interactions, offering a unique perspective on how individuals collectively respond to similar experiences and stimuli.
