Workgroup Research Design and Statistical Data Analysis

  • Description
  • Description

    The workgroup Research Design and Statistical Data Analysis (head: Dr. Levente Kriston) exists since 2009 and aims at testing and developing methodological and statistical tools for medical and behavioral sciences.

    The group performs several research projects addressing methodological and statistical issues in the context of:

    • evidence-based medicine and comparative effectiveness research (e.g., clinical trials, systematic reviews, and meta-analyses),
    • health services research and implementation science (e.g., evaluation of complex interventions and analysis of routinely collected data),
    • medical decision making (e.g., translational science and information processing),
    • psychotherapy research (e.g., process and outcome research),
    • epidemiology (e.g., latent class models and investigations of etiologic factors),
    • as well as outcomes research and psychometric evaluation (e.g., screening, diagnostics, development of questionnaires, measurement of adverse effects).

    In addition, the group contributes to the development of scientific contents in medical education and the training of postgradual fellows in research methods.
