Twente Intervention and Interaction Machine (TIIM)

Twente Intervention and Interaction Machine (TIIM) is a software created by the BMS Lab. Researchers, teachers, and students at the University of Twente can use the dashboard’s web application to create interventions, longitudinal studies, ESM studies and questionnaires. Subsequently, through the TIIM’s mobile application, the researcher/teacher/student can gather data and/or distribute information/content to participants about different topics. It allows researchers to create sets of questionnaires and present them to participants based on a schedule or conditions. In addition, the studies can be adapted to individual participants due to the option to add item routing and questionnaire conditions. TIIM allows for interactive feedback, notifications and calculations, while giving you a better picture of your participants or patients by collecting wearable data when desired. 

TIIM is ISO/NEN 7510/7512/7513 and GDPR compliant and it operates on ISO/IEC27001 certified infrastructure


If you have any requests, questions or concerns regading TIIM, please let us know by sending an email at dashboard-bms@utwente.nl.

If you have questions or concerns regarding your study, please include your study ID (the four numbers in the URL when your study is open) in the email.

TIIM For Research And Education

TIIM can be used for cohort studies, eCoaching, interventions, experience sampling, EMA/EMI, pilot testing, clinimetrics, wearable data, clinical trials and education & eLearning.

The IsolatieCoach research used TIIM as an interactive and personalised eCoach to support people during their process of isolation. Participants engaged in an interactive questionnaire where based on their answers, the app provided feedback. 

Another example is the project: Using motivational interviewing combined with digital shoe-fitting to improve adherence to wearing orthopaedic shoes in people with diabetes at risk of foot ulceration: study protocol for a cluster-randomized controlled trial. TIIM was used to collect participants biometric data (steps and heart rate) and sleep, through their wearables. The full article is available on this link.

Best practices

To reduce potential issues and challenges, keep the following points in mind before using TIIM for your research:

  • Planning Your Research Design
    1. Think about what you would like to measure. When? What will it deliver afterwards? And how does TIIM fit within your research? This helps you realize what you need to build, when and how much time it will likely take.
    2. Take practical aspects into account: is there an easier way to do it? Uncertain? Ask the BMS Lab.
    3. Consider the limitations of the software to your study. Keep in mind that TIIM is in continuous development which means that bugs might be introduced as a result.
    4. Please note that in all cases users of TIIM are fully responsible for their own study design, data collection and the resulting data. Collecting data that may be deemed sensitive or medical in nature in TIIM is possible. In these cases, researchers should always go through the required procedures (e.g.: ethical approval from a central ethical commission, MDR approval (contact person: p.oosterhoff@utwente.nl) or AVG registration) for their individual studies.
    5. Be mindful of the size of the study! The more participants interventions, modules and module items you have, the longer it will take for the studies to load and download.
  • Developing Your Research
    1. Ensure that you have approximately 2 – 3 weeks to build your research. You might need to adapt your methodology based on TIIM’s functionalities (see “Further Support” section) or you might need time to get an answer from the BMS Lab.
    2. Your introduction screen should adequately inform your participants and meet the BMS faculty’s ethical standard on informed consent.
    3. Any time you make new additions, make sure to regularly test your research from the participant’s perspective.
    4. Duplicate your research to have a clean backup version.
    5. Test your final version as a participant.
    6. Download your data metrics to ensure that the data output fits with your research.
    7. Found a bug or issue? Please inform us.

Best Practices for ESM in TIIM

TIIM is undergoing a major update in which ESM studies will be easier to do. Until then, here are a few tips and tricks on how to do an ESM study in TIIM.

  • Creating the questionnaire

    You will need to create the module (questionnaire) only once. Then, using the duplicate function, you can duplicate it as many times as you wish to send it.

  • Sending the modules at random times

    You can generate the random times at which you can send the modules in, for example Excel, and then use the times generated for creating the schedule.

    Disclaimer: All participants will receive the modules at the same time.

  • Notifications & Reminders

    In TIIM you can send notifications & reminders to the participant. In the cases when you would like to have them being sent out at random times, we propose to use Excel to generate the times and create the schedule based on that using the specific date function.

BEST PRACTICES FOR Learning & E-diarisation IN TIIM

Here are few tips and tricks on how to do an E-diarisation study in TIIM.

  • Working with ‘goals’

    Oftentimes when TIIM is used as a tool to facilitate learning, participants are asked to specify their learning goals or objectives. Using the dynamic text function can be used to call back to the goals or objectives specified by the participants.  

    Keep in mind that the module(s) that specify the goals and graphs should be part of the same intervention.  

  • Using graphs in TIIM

    The item type graphs allows for visualisation of the progress of the participants.  

    You can use a different item type (for example, number slider) to ask participants to assess their knowledge or familiarity with a chosen goal. Then, using dynamic text option in the graph item type, you can create a graph showing their progress over time by dates. You can select the modules and the items from which the values in the graph will be shown. 

  • Minimising missing data

    We advise you to carefully consider the starting moment of the study, choosing it to be close to a real life case or trigger that will start the process (such as lecture that is held on a specific day). Then, all of the participants can be automatically receive the intervention once it is available to them, by either scheduling the intervention to start at a specific date and time. 

    It is also possible to send reminders (both to all participants or individually) to ensure their retention. 

  • Dealing with missing data

    Missing data can happen in the instances when participants have not answered specific modules. We advise you to consider the data as if it is liked, and not fixed (for example, in time). If linear processes are used, the missing points can be interpolated. It is also advisable to consider whether carefully examine whether you want within person or between person results, i.e. with high inconsistency of some individuals between person results analysis can still be done if the group is large enough. 

    For the participants it may be motivating and useful to use the graph item type, as it allows them to visualise their progress. You can also download the data per participant and individually send it to them to increase engagement or adherence.  

    Lastly, having enough data points may minimise the impact of the missing data and currently in TIIM all items in a module are mandatory to be answered.
