Assessing mood and behaviour using a smartphone application

Madeleine Wallis and the research team at University College London, have developed a smartphone application with a series of short decision-making games and surveys.

The aim of the research is to try and understand how neurological conditions, including Parkinson’s, influence mood and decision making.


People living in the UK aged between 18-80 who have access to an iOS (iPhone/iPad) or Android smartphone/tablet, and belong to any one of the following groups: 

300 people with Parkinson’s

300 people unaffected by any psychiatric or neurological condition

300 people with a history of anxiety or mood disorder but no diagnosis of a neurological condition


You will be asked to download an app to their smartphone or tablet and asked to play a short decision-making game and complete surveys that take 3-5 minutes each. The time spent on the app will be no more than 10 minutes per day for the duration of the 3-week study. No previous experience in playing smartphone games is required. 

For full information about the research:

If you are a person with Parkinson's please read the Parkinson's Participant Information Sheet. If you are a person without Parkinson's please read the General Participant Information Sheet
