Delphi Study : Core Biostatistical Competencies and Attitudes towards Biostatistics among Health Researchers

A Delphi study was conducted to identify the biostatistical competencies that all health researchers should possess and to draw up a list of attitudes towards biostatistics they may hold. The panellists were selected from French-Speaking Belgian universities and were biostatisticians, health researchers or psychometricians. Over three rounds, panellists rated each item on a 7-point Likert scale and provided qualitative feedback and suggestions. Consensus was defined as a median ≥ 6 and an interquartile range < 1. Items were iteratively added, removed, or refined between rounds. Response stability between the first two rounds was assessed using the Wilcoxon signed-rank test. Here are joined the feedback (in french) with quantitative and qualitative results sent to the panel members after each round. The database associated to this study will be submitted after acceptance for publication.
