Participation in: Research to Detect Mental Health Conditions through Digital Behavior on a Smartphone.  



You are being invited to take part in research. This research is being carried out by Behavidence Inc. Behavidence ( is a commercial company that builds mental health navigation tools to help monitor mental health conditions such as Depression, Anxiety and ADHD (Attention Deficit Hyperactivity Disorder) using the technology of digital phenotyping. (Digital phenotyping refers to the science of leveraging behavioral data from smartphones to characterize individual human traits.) Before you decide to join the research, it is important that you understand why this research is being done and what activities will be involved. Please take time to read and understand the following information sheet carefully. Please email us at if you have any questions. Please note that this research study is not meant to diagnose or treat medical problems.


Why am I being invited to take part in a research study?  

We invite you to take part in this study because you have agreed to help research in developing a digital similarity score for mental health conditions. . There will be a total of 100 persons with a mental health condition in this study in addition to 100 control participants. All participants will be recruited online.

Why is this research being done?  

The purpose of this investigational study is to learn if passive behavioral data, not content, collected through smartphone applications (apps) may be helpful in understanding more about affective mental health conditions. This will enable us to create accurate digital behavioral models for these conditions  based on this data.  This study involves downloading the Behavidence app to your smartphone and answering a short questionnaire (less than 2 mins).


How long will the research last and what will I need to do?  

You will need to download the app and use it as per your convenience for a period of 30 days. You will also answer the questionnaire only once i.e. when you sign up for the app.  


This research study collects two types of data: 


  1. Passive Data

The app will passively collect behavioral data from your phone once you have downloaded the app, but will not collect ANY content or any personal information. The data will be automatically collected unless you delete the app from your phone.  Passive data means information about when your phone is turned on or off and when your phone is being used or not used.

The forms of passive data that we collect are App open and close, digital screen time, digital sleep time and gyroscope. 

   2. Active Data Collection  

The app will offer you the questionnaire to answer only once, while onboarding, during the 30 day duration, which you are encouraged to answer. 


All Data Collected 

You are free to stop the app collecting data at any time by deleting the app from your phone. Any data that has been collected before you delete the app will be used for research purposes, but no further or new data will be collected. 


Research Procedures

If you qualify to take part in this research study, you will undergo these research procedures:

  • At the time you decide to respond to the advertisement, you will be asked to sign up and provide basic demographic details. We will ask you to complete a standardised  questionnaire to get a baseline assessment. 

  • Sign up can be done securely using your preferred email address and password

  • This will take 2-5 mins. This app will be password protected using a password of your choice, so no one else will be able to access the app.  You have the choice to log in anonymously. This means we will not be able to restore your data should you delete the app and reinstall it again. 

  • The app will collect passive data but no personal content data will be tracked or collected. All of the data collected is immediately encrypted on the phone as soon as it is collected. .

  • You are free to use the app according to your convenience, 


I am not very technologically inclined; how will I be able to use the app? 

The app is very simple to use. It will give you a daily Mental Health Similarity Score to ADHD, Depression and Anxiety. There is also a journal option. You can simply use the app to monitor your mental health, journal and also to manage your digital use just by opening the app. 


Is there any way being in this study could be harmful to me?

As a result of your participation in this study, you are at risk for side effects listed in this section. This may or may not happen.There may be other unforeseeable risks.


  1. Data loss 

It is also possible that although the app has many features to keep your data secure, there is a remote chance that your data or phone could be stolen, 22although all your data other than the one you see on screen is encrypted. If this were to happen, someone would know  your MHSS scores and your journal entries. 

Steps to ensure confidentiality:

The app is HIPAA (Health Insurance Portability and Accountability Act) compliant, which ensures absolute confidentiality for our users. There is also an option to login anonymously where the user has to enter no personal information. Some of the steps that we take to ensure confidentiality are as follows-

  1. All the data that we hold for our users is encrypted. We create random IDs when you log in, which can in no way be tracked to your real name/email if you choose to enter. 

  2. If we give any third parties access to our data, we add another level of encryption. 

  3. There is an option to sign in anonymously. If you choose to do so, we will not collect any identifiables. 

  4. We have an efficient alert based system for any external threat to our servers, i.e., we are in complete control to protect our information if there is an external interference. 

  5. As noted above, all data the apps collect are not monitored in real time and no one will be able to respond to that data in real time. If at any time, and for any reason you need help you can email the research coordinator at
