Complex methods - brief interventions.

Research

I care greatly about helping individuals make a positive change in their life to better their own and others physical and mental health. In particular, my focus is on the development and evaluation of novel interventions, including research on the methodological advancements and limitations of both.

Some of the research projects which I work on have grown into research programs and are presented below. Please see Research projects for a complete list of all my research projects, and Publications for published work.

Research programs

Text messaging alcohol interventions
TOPHAT

Five projects focusing on the use of mobile phones in alcohol interventions. Including three trials, one feasability study and a meta-analysis.

College student's mental health
MENTAL

Four projects focusing on college students' mental health, including a trial of a text message intervention, WHO-WMH-ICS surveys, Covid-19 specific surveys, and a meta-analysis.

mHealth - Multiple Lifestyle Behaviors
MoBILE

Seven projects, including seven trials and qualitative studies, of mobile phone multiple lifestyle behaviour interventions among different populations across the lifespan. Including meta-analysis, registry studies, and dissemination projects.

Text messaging smoking cessation interventions
NEXit

Five projects, including trials, qualitative and precision health studies, of text messaging smoking cessation interventions among five different populations: college and high school students, patients with elective surgery, primary health care visitors, and online help-seekers.

Electronic screening and brief intervention to reduce risky drinking
AMADEUS

Two trials of brief alcohol interventions emailed to college students in Sweden. Both effectivness and efficacy trials, including a unique study of research participation effects.

Please see Research projects for a complete list of all my research projects.

Dissemination

Behaviour change interventions which are the produce of scientific research, and which have been proven to be effective, should be disseminated to those who may benefit from them. I therefore always ensure that effective interventions that stem from my own research are available for free to the general public.

question_answer
Student healthcare alcohol portal

Electronic screening and brief intervention for reduced alcohol consumption proven effective among university students. Since 2010, student healthcare units across Sweden have been sending email invitations to students to screen themselves and be given advice for change. The first decade saw over 1 million emails sent with over 200 000 students responding.

smoke_free
Text messaging smoking cessation intervention

Freely available 12-week smoking cessation intervention delivered via text messages. Effectiveness established among university and high school students. In 2020 a new trial including online help seekers and primary health care visitors has been initiated.

psychology
Text messaging positive psychology intervention

Freely available 10-week positive psychology intervention delivered via text messages. Effectivness established among university students.

Teaching

I have taught extensively at both medical and technical faculites since 2009, and have been examiner and/or supervisor for over 50 bachelor and master theses (see full Teaching history). I am currently examiner and/or course leader for the five courses presented below.

Epidemiology
Medical Faculty PhD course

This is a course designed to help you ask the right questions. Sometimes these questions may be directed to an epidemiologist, sometimes to a data analyst, and sometimes to yourself.

Good research stems from knowing that you will have to make bad choices. But knowing which ones are least bad, and which ones get you closer to your goal, is key in moving your research field forward. You should appreciate the complexities, understand what can be done to alleviate difficulties, and always report your findings in light of your decisions.

Digital lifestyle interventions - from idea to implementation
Medical Faculty PhD course

The course aims to provide a deeper understanding and knowledge of digital lifestyle interventions. The course includes elements that consider the planning and design of digital life intervention, critical interpretation and evaluation of the results, and implementation in health care or other arenas in society.

During the course, students will write their own individual work where they will either design a new digital lifestyle intervention or refine or implement an already ongoing intervention within the framework of their dissertation.

eHealth: Aims and Applications
Masters program in Medical Science

This course is an introduction to eHealth which aims to make the concept of eHealth more transparent with an anchoring in its interdisciplinary nature. The course is taken by both students from both the medical and technical faculty, and they interact in learning about the interprofessional nature of the core topics.

eHealth: Digital Applications for Promoting Health and Preventing Disease
Masters program in Medical Science

This course has three themes which focus on how digital applications for promoting health and preventing disease are developed, implemented and evaluated.

Behaviour change theories and behaviour change techniques are discussed in conjunction with user participatory design of digital applications. Factors which affect implementation of innovations within an organisation, and how innovations can be evaluated with respect to both effectivness and dissemination, are discussed from both theoretical and methodological points of view.

Project Semester including Bachelor Thesis Project: Secure Systems
Information Technology, Master of Science in Engineering

This is a semester long course including two projects (one of which results in a bachelor thesis). The course includes a range of topics, including: security terminology and security principles, analyzing situations from an information security standpoint, consideration of risks and threats, safe identification and authentication, and basic cryptography.

The course also includes group work and learning how to plan and execute projects.
