Introduction
MetricWire is a platform for mobile data collection through research participants' own iOS and Android mobile phones.
Through partnership with MetricWire, m2c2kit assessments can be added to MetricWire studies.
MetricWire is a strong option for studies using EMA, scheduling, and notifications. It supports complex scheduling, notifications, and compliance tracking, while also providing a seamless participant experience through a single app. It also prevents duplicate completion of the same M2C2 assessment within a session. This option does require a MetricWire license, so you will need to contact their team for an estimated cost. The m2c2 team cannot provide this for you.
A note on configuration. There are two options for deploying M2C2 assessments in MetricWire: a URL approach or an Embedded approach. The URL approach requires contacting the PSU team to establish a study for the assessment data to be securely stored on M2C2 servers. Costs may be lower if you select this option; however, storing the assessment data outside of the MetricWire platform requires internet connectivity or a data plan for assessments to function properly. If your participants do not have reliable access to a data plan, or internet, or if your institution does not allow researchers to store data on outside servers, you may need to work with the MetricWire team to include access to the assessments in your license.”
MetricWire M2C2 Deployment Options
| Feature | M2C2 Web URL | Embedded M2C2 |
|---|---|---|
| How assessments are deployed | M2C2 assessments are accessed through web URLs within MetricWire | M2C2 assessments are embedded directly within MetricWire |
| Cost | No additional M2C2 assessment package cost beyond the MetricWire license | Additional cost for the MetricWire cognitive assessment add-on package |
| M2C2 data storage | Penn State secure server | MetricWire server |
| Data access | Export through the M2C2 web portal | Download directly from MetricWire |
| Scoring | Score through the M2C2 web portal | Use the M2C2 Python scoring pipeline in your own computing environment |
| Data format for scoring | Managed through the M2C2 portal workflow | JSON files downloaded from MetricWire |
| Offline capability | No | Yes |
| Technical effort | Lower — portal-based export and scoring | Higher — requires JSON download, Python, and the M2C2 scoring pipeline |
| Best fit | Studies wanting a simpler, lower-cost workflow that does not require offline assessment delivery | Studies requiring offline assessment delivery and able to manage data and scoring locally |
