Master thesis/internship project: Dropout Prediction in Digital Health Interventions

#datascience #digitalhealth #machinelearning

Project context: Digital Health Interventions (DHIs) and, more specifically, mHealth apps show vast potential in supporting health care systems with the globally increasing prevalence and economic costs of chronic diseases – the leading causes of death and disability worldwide. However, despite the availability of evidence-based DHIs, a substantial proportion of users do not adhere to them, ultimately dropping out and thus not receiving treatment. To solve this problem, we collaborate with several project partners that develop and distribute mHealth apps targeting food literacy, substance use, high blood pressure, sleep hygiene, and diabetes. Analyzing real-life longitudinal data of their apps, we aim to identify factors influencing non-adherence and explore machine learning methods that can effectively predict dropouts. Further information can be found on the project website.

Candidate profile: We are searching for highly motivated, proactive, and self-directed students with a general interest in digital health. You should be proficient in creating clear and comprehensible R/Python scripts that can be reused by other parties to explore and analyze large datasets. You should have experience cleaning and organizing data and applying relevant statistical models. You will be fully supported as to relevant theory from medical and behavioral sciences and how to write your thesis for a healthcare audience.

Master thesis/internship tasks: You will clean, organize, and analyze given data sets, conduct statistical analysis, engineer and select feature variables, and explore machine learning methods that classify potential dropouts in mHealth apps. Your work will be part of a more extensive scientific study which is subject to being published in a renowned medical peer-reviewed journal, which you are invited to co-author based on your contribution. The project can be conducted entirely remotely. We highly encourage members of underrepresented groups to apply. Students from other universities than ETH Zurich are also welcome to apply.

Start: Anytime, as soon as possible

Methodology: Longitudinal data analysis

Duration: 6 months (or to be discussed)

Master Thesis Offer: Business Model Development for the AI-based Mindfulness Tool “Breeze”

Background: Non-communicable diseases (NCDs) impose enormous health burdens on individuals and lead to substantial health economic challenges. NCDs’ risk factors relate primarily to a lifestyle characterized by tobacco and excessive alcohol consumption, physical inactivity, or an unbalanced diet. This lifestyle leads to overweight and obesity, hypertension, and other cardiovascular and neurodegenerative diseases. Unfortunately, individuals with lower socioeconomic status (SES) are substantially more affected by NCDs. These individuals are also significantly underrepresented in clinical and non-clinical trials. As a result, health interventions are potentially only effective for individuals with higher SES and do not address those most in need. Therefore, it is essential to understand better how to reach and engage individuals with lower SES while developing and delivering health interventions. As a first step, we have already developed and successfully evaluated a novel AI-based Mindfulness Tool “Breeze” for the prevention and management of physical and mental health (10.2196/22803, 10.2196/22802, 10.1145/3369835). Breeze utilizes the microphone of a smartphone (or a smartphone with a Bluetooth connected headset) to detect breathing patterns in quasi-real-time to then provide biofeedback in a novel and gamified way.

Goal: The thesis has the objective to develop a business model for Breeze. This involves the following activities:
  1. To understand better the competitive landscape of mindfulness tools (see, for example, 10.2196/29412),
  2. To explore whether Breeze should be either further developed as a business-to-consumer (B2C) or business to business (B2B) product.

Candidate Profile: We are searching for a highly motivated Master student proficient in English and comfortable with desk research and qualitative research methods (e.g. conducting interviews with representatives of mindfulness companies and other experts in the mindfulness sector, such as investors, etc.). The ideal student has excellent communication skills and experience in business model innovation, entrepreneurship and digital health. Moreover, the master student has excellent grades and can invest 100% effort into this thesis.

Start: as soon as possible

Duration: 6 months

Interested students are invited to send an email with their (1) motivation letter, (2) CV, and (3) transcript of records to Prof. Dr. Tobias Kowatsch (Scientific Director CDHI ETH Zurich & University of St.Gallen and Assistant Professor for Digital Health, University of St.Gallen) at The thesis will be co-supervised by Prof. Dr. Felix Wortmann (Scientific Director Bosch IoT Lab) and Dr. Jan-Niklas Kramer (Innovation Manager, CSS insurance, Lucerne).

Master Thesis or Semester Project (3 or 6 ECTS) Offer – Elena+: Care for COVID-19

Project context: In Spring 2020, during the height of the pandemic in Europe, the Elena+: Care for COVID-19 smartphone app was developed by a group of international researchers. Functioning as a digital health intervention delivered by a text-based chatbot, the app coaches individuals through a series of psycho-educational coaching sessions (related to anxiety, sleep, diet etc.). The general project aim is to examine whether a chatbot-delivered smartphone app can help reduce the collateral damage of lockdowns (i.e., increased anxiety because of the situation, lack of exercise because of staying indoors etc.). Further details can be read in the study protocol paper.

Project status: The app is currently live and collecting data in Switzer- land, United Kingdom, Ireland, Spain, Colombia, and Mexico, and is available in English and Spanish (European and Latin American versions). The app has had approximately 7000 downloads.

Candidate Profile: We are searching for a highly motivated student, comfortable with using R/Python to explore large datasets. The ideal student will have some experience cleaning and organising data, as well as applying relevant statistical models.

Master’s thesis
For those interested in writing a master’s thesis, a general interest in healthcare, chatbots and marketing is desirable. However, your background area of study is not important provided you are motivated to learn. You will be fully supported as to relevant theory from social/behavioural sciences and how to write your thesis for a healthcare/marketing audience.

Example tasks

  1. Read and organise relevant literature from healthcare, information systems and marketing fields.
  2. Create clear and comprehensible R/Python scripts that can be re-used by other parties.
  3. Split tuple items into separate variables (for ex- ample, with regex).
  4. Create new composite variables (e.g., from psy- chometric item scores).
  5. Apply join methods to different datasets.

Example analyses

  1. Longitudinal regression models (e.g., linear regression and more advanced applications such as ARMA models).
  2. Analysis of Variance (e.g., within-subjects ANOVA, between-groups ANOVA)
  3. Exploring and codifying free text entries

Start: Anytime, as soon as possible

Methodology: Longitudinal data analysis

Master thesis/internship project: Passive mobile sensing in anxiety patients prior to and during cognitive behaviour therapy

Finishing your studies at the University of St. Gallen or ETH Zurich and looking for an exciting thesis matter? Why not considering one of these:

The Experimental Psychopathology and Psychotherapy group (Dual affiliation with the Psychiatric University Hospital and Dept of Psychology, UZH) offers an open master thesis project on passive sensing data collected through a mobile app within a randomized clinical trial on anxiety (SNSF OPTIMAX project, optimizing psychotherapy for anxiety disorders, headed by Prof. Dr Birgit Kleim). Passive sensing data was collected in collaboration with the group of Dr Tobias Kowatsch at the Centre for Digital Health Interventions, ETH Zurich and University of St.Gallen.

The OPTIMAX project aims at improving the treatment of anxiety disorders by establishing improved prediction models. Participants are patients with a primary diagnosis of anxiety and the treatment consists of 16 to 18 weeks of cognitive behavioural therapy. The aim of the master thesis is to investigate whether passive sensing data are feasible to describe different behavioural patterns in everyday life and whether these data can be used to predict treatment outcomes. Passive sensing data are collected pre, mid and post-treatment, therefore changes in the course of treatment can also be investigated.

Potential master candidates or interns should have an interest in digital assessments, data science and/or clinical psychology/psychiatry and, ideally, experience working with larger data sets. They will be supervised by the teams of Prof Kleim and Kowatsch.

Starting point: Immediate or upon agreement
