Each study has an overview page which describes the different parameters chosen during the study design and allows the changing these options if needed. The following image shows study overview page for the study created in Creating a New Study section.
All the elements shown in this page are self-explanatory. You also have the option to edit the study and changes the configurations which you had defined previously.
If by the time you decide to change the study you already have enrolled one or more participant whose participation period is not passed, you need to make sure the changes are sent to their devices. You can read more about this in Modifying a Study section.
In Study Overview page you also can see the list of participants currently registered in the study, and some basic information from each. The following image shows the information about the only participant in our sample study.
Each of the fields shown above are described below.
This shows the ID of the participant in Ethica. Each participant is allocated a unique ID, and this ID is used everywhere when referring to this participant.
This shows a list of devices used by the participant. Each participant can use one or more device during the their participation period.
If more than one device is used at the same time by the participant, the uploaded data can potentially be ambiguous, as Ethica cannot determine which was in fact carried by the participant as the main device and shows their behaviour. We advise if a participant listed with more than one device, make sure they don't have Ethica running on both their devices at the same time.
This shows for what percentage of the time Ethica app was running on participant's device and was trying to collect data per specifications of this study. This is calculated by counting all time slots where the participant provided any data, and divide it to total time slots in their participation period so far.
For example if participation period is from June 1st to June 15th 2016, this value is calculated by counting the number of time slots participant has reported any sort of data, divided by total time slots available in these 15 days. This is considered as a crude measure of compliance. You can read more about how to measure compliance for each participant in Compliance section.
This reports the last time the server received data from the participant. Ethica app performs all data collection on the smartphone regardless of the network connectivity. The app encrypts and stores the data on the smartphone until it finds an opportunity to upload them. So lack of Internet connectivity cannot cause data lose.
On the other hand, if participant does not upload any data for a long period, that can be a point of concern as it might be an indication that participant is not complying with the study as expected.
This value simply shows when was the last time this participant uploaded data related to this study. Study organizers based on the context can interpret this value and decide whether they should contact the participant for a follow-up or not.
As mentioned before, each participant has a participation period which defines the period of time when the data collection takes place. This date shows at what point the data collection for this participant was started (or will be started).
This date shows at what point the data collection for this participant was ended (or will be ended).
Each row in Participants section is related to one participant, and it can be extended by pressing the + icon on the left side of the row. Expanding the row for a given participant provides additional information about the participant, as shown and described below.
Each smart-device used for data collection is allocated a unique ID which is shown here. This ID is independent to the participant using that device and is unique per smart-device. This ID remains unique even if the Ethica app is uninstalled and reinstalled on that smart-device.
When a device is used for a given participant in a given study, the same device cannot be used for another participant, until the current participation period is over. This guarantees the data coming from the device is for the participant who used it to join the study.
The make and model of this device.
The Bluetooth MAC address of this device, if available.
The Wi-Fi MAC address of this device, if available.
Whether the device registered for Google-Cloud Messaging (GCM) services or not. Ethica uses GCM technology to communicate with participants device's when needed. If the device is not GCM enabled, the device will not receive requests sent from the server, for example to receive changes made to the study, or to receive a survey.
Majority of the devices are GCM enabled. The reasons for a device being not GCM enabled includes the device is too old, the software is outdated, or the device is not having a valid Google account.
For what portion of time this device has been in operation. If the user has only one device, this value is the same as In Operation value explained above. Otherwise this value shows the amount of this this device has been in operation, while the previous entry shows the maximum time the user's devices have been active and operational.
When was the last time this device sent any data to Ethica servers. If the user has only one device, this value is the same as Last Seen value explained above. Otherwise this value shows the time Ethica received any data from this device.
