Health-2-Market was a 3-year long Coordination and Support Action, funded by the European Union’s Seventh Framework Programme for research, technological development and demonstration (Grant Agreement No 305532). H2M aimed at providing training and individual support to Health / Life Sciences researchers in the process of translating their research results into successful new business ideas. With a view to properly adapting the training offer of the project to the needs of Health / Life Sciences researchers in terms of entrepreneurship and business skill development a Training Needs Analysis (TNA) was conducted. In this context, H2M launched an online survey targeted at Health / Life Sciences researchers who have been involved in EU health projects. In particular, the objectives of the survey were: To formulate a descriptive understanding of various aspects of commercialisation and training needs of the main target group of the project; To divide this target group into homogeneous sub-groups (clusters) along a number of key characteristics such as demographics, commercialisation attitudes and needs; To understand preferences and importance of different aspects and needs through the analysis of: Knowledge areas that can influence commercialisation behaviour; Training modalities that have an effect on the intention to participate and /or on the perception of the usefulness of a commercialisation training; Variations identified over different sub-groups. The survey was dispatched to a database composed of 7,991 unique contacts of participants in previous health projects, accessed through the Directorate General for Health and Food Safety of the European Commission. The initial aim of at least 50 complete responses was overwhelmingly surpassed: 637 respondents completed the survey in full. The “H2M survey questionnaire for the identification of commercialisation training needs of Health Researchers” document contains the questionnaire that was utilised in the frame of the survey.
