Mediation Analysis workshop

Testing Mediating Mechanisms and Moderating Factors in Prevention Work


In recent decades, there have been major advances in the design of studies to evaluate efficacy and effectiveness of preventive interventions.  These advancements contributed to the quality of evaluation studies and the confidence in the findings.  Most evaluation studies still focus only one of the most fundamental questions: Is the program effective? Relatively few research focus on other critical questions such as why, how, and when is a prevention program effective? Nevertheless, addressing these questions often requires complex statistical modeling, and some of these techniques are not commonly available to research community yet.

The goal of this workshop is introducing the new conceptual developments and statistical techniques that can be applied to testing mediating mechanisms and moderating factors of program effect.  The audience will be provided with conceptual arguments about mediation and moderation effects and recent developments in modeling mediating mechanisms and moderating factors in prevention research.

Learning the theoretical underpinnings and application of these techniques may provide researcher with opportunities to address intriguing research questions such as: How does a program influence targeted outcomes? Does the program work consistent with the program theory? Which components of the program do account for the program effect? What factors do boost or hinder effectiveness of programs? Do the effect of a program vary across different socioeconomic conditions? Are the processes that explain the program effect generalizable across different groups? Answering these questions is essential for a comprehensive understanding of the prevention programs. This understanding may also contribute to translation of research findings into practice. For example, understanding the effect of program components may guide decisions regarding program modification.  Similarly, understanding the factors that may influence program outcomes may guide decisions regarding program adoption.


09:30 – 10:00    Introduction – Fabrizio Faggiano

Instructor: Metin Ă–zdemir, Ph.D.

Metin Özdemir  received his doctoral degree in Community and Applied Social Psychology at the University of Maryland, Baltimore County in 2009.  He is currently affiliated with the Center for Developmental Research, Örebro University (Sweden), where he coordinates a Master’s program in prevention science. His research focuses on youth adjustment in normative populations and testing effectiveness of preventive interventions for youths and families. He has been teaching courses on prevention science theory and methods including advanced level courses on testing program effectiveness.

Co-instructor: Fabrizia Giannotta, Ph.D.

Fabrizia Giannotta has received her doctoral degree in Social and Developmental Psychology at University of Torino (Italy). She is currently affiliated with the Center for Developmental Research, Örebro University (Sweden), where she holds a lecturer position. Her research interests focus on the study of protective and risk factors in adolescence and the cross cultural adaptation of prevention programs to combat risk behaviors in adolescence.  She has been teaching courses on program development and evaluation and on research methods to evaluate programs effectiveness, in the Master program in prevention science at Örebro University.

Screentime related prevention research

“Prevention of problematic and addictive use of screen media – a call for action”

The first part of the workshop will give a comprehensive and critical introduction into the topic and give positive examples from new German and Spanish interventions.

  • Paula Bleckmann, Hanover, Germany “Current state of media effects research – first evidence of its neglect in preventive practise due to conflict of interest”
  • Michael Seidel; Bonn, Germany:– “Supporting parents to limit children´s problematic media use. Results and lessons learned from MEDIA PROTECT”
  • Daniel Lloret Irles, Spain: “Teens and their parents as targets in an intervention to reduce problematic use of screen media”

The second half of the workshop will serve as discussion forum and possible kickoff meeting for a new EUSPR working group “eHealth/screen-related prevention” with three possible aims:

First, to serve as a starting point for a network of researchers and practitioners based on a widened and balanced understanding of “eHealth”: working to reduce problematic use of screen media and using new media for health promotion purposes where appropriate;

Second, to avoid the errors made in the past of prevention science, e.g. trusting economic stakeholders (in this case: media industry) to develop concepts for prevention;

Third, to discuss possibilities fo a joint European intervention design for prevention of problematic use of screen media that could be proposed to future EU funding streams.

Fourth EUSPR Conference and Members’ Meeting, 13-15 November 2013, Paris, France


Understanding differences in prevention outcomes

It is well known that differences in health and wellbeing within and between populations are influenced by a range of biological and social factors.

However, less attention has been given to identifying how differences in these factors may influence the experiences or outcomes of prevention work. Prevention interventions and policies may also inadvertently generate health and social inequalities by disproportionately benefiting some populations, to the disadvantage of others.

The development of frameworks such as PROGRESS Plus (Place of residence, Ethnicity, Occupation, Gender, Religion, Education, Socio-economic status, Social capital, Age, Disability and Sexual Orientation) has helped to provide a focus for research, but how do these factors influence intervention outcomes, and how do we design prevention policies and programmes which take them into account?

The 2013 EUSPR Conference focused on the important role of modifiers of prevention outcome, and examined the best ways in which diversity can be incorporated into research and practice. Keynote speakers presented the latest findings from research investigating modifying factors such as age, gender, ethnicity, family and socioeconomic status.

We are also extremely pleased that pre-conference workshops were held in collaboration with the Science for Prevention Academic Network (SPAN) project, which aims to support the development of prevention science education across the EU.

As part of Day 2 of the conference there was a special guided poster session with prizes for the best Early Career Posters including cash prizes and one year’s free Society membership. The poster prizes were supported by SPAN.

Venue: Le Centquatre, 5 Rue Curial, 75019 Paris, France. MAP
