Conference contributions in Fall 2021

This years conference season is about to begin and I’d like to announce the following contributions our group makes: ISOQOL Felix Fischer, “Positive and negative predictive values for continuous test scores”, Brief Oral, on Demand

Webinar: Scoring of IRT based PROs

Yesterday, the PRO scoring webinar took place. Find my slides and a recording of the talk here. Feel free to get in touch if you have questions on the material.

DEPRESSD Webinar - Addressing overestimation of prevalence based on self-report questionnaires: Are there cost-effective alternatives?

For those who couldn’t make it to the first DEPRESSD Webinar, you can watch the recording here here. The video is also posted on the DEPRESSD website.

HARMONY training schools

The COST Action HARMONY, devoted to make statistical tools for test evaluation and disease prevalence estimation more accessible, does some training schools (online and hybrid) over the summer. Check it out here.

Presentation: Von der Herausforderung, individuelle Veränderungen der Lebensqualität zu erfassen

I held a talk at this years DKPM-Kongress (in German!) - it’s about the challenges if one wants to assess change in quality of life individually over time.

New Publication: Achieving reliable pain change scores for individuals in the postoperative phase carefully choose sampling density, test length, and administration mode

Alexander Obbarius recently published a study investigating the impact of sampling density, test length, and administration mode to assess change in pain. The paper can be found here.

New Publication: Building a Value-Based Care Infrastructure in Europe: The Health Outcomes Observatory

Our new study introducing the Health Outcomes Observatory (H2O), a multi-jurisdictional ecosystem to incorporate patient-reported and other health outcomes into health care decision-making across Europe, is out! Leaders at the European Union’s Innovative Medicines Initiative are developing a large-scale multi-stakeholder international ecosystem to incorporate patient-reported outcomes and measures to improve patient engagement and drive value.

DEPRESSD Webinar - Addressing overestimation of prevalence based on self-report questionnaires: Are there cost-effective alternatives?

The DEPRESSD Team is planning to host a series of webinars for project collaborators and other interested researchers and clinicians. The first webinar will cover the topic: Addressing overestimation of prevalence based on self-report questionnaires: Are there cost-effective alternatives?

New publication: More flexible response functions for the PROMIS physical functioning item bank by application of a monotonic polynomial approach

Carl Falk from McGill University in Montreal, Canada and I investigated the use of a more flexible IRT model to fit the PROMIS Physical Function Itembank. The paper has been now published in Quality of Life Research’s nonparametric IRT section.

Webinar: Scoring of PROs using IRT

I’m doing a short webinar about the basics of PRO scoring using Item-Response Theory on July, 8th at 4pm (CET). The goal is to give you a short overview of scoring options for PROMIS and other IRT based measures, with a focus on interpretation.
