Despite the multiple achievements in Huntington’s disease (HD) research over the last years, effective disease-modifying treatments are still lacking. Because clinical progresses imply a strong commitment from HD families, they should be heard in this process. Our aim was to establish which factors affect the willingness of persons at risk for HD (HDRisk) and persons with premanifest HD (PreHD) to take part in studies. Specifically, this work investigated the view of the Dutch HDRisk and PreHD communities regarding research participation.
The European Huntington Association created a multi-language online survey to capture the research perceptions and experiences of persons with HDRisk and PreHD. Questions assessed research experience and knowledge, information sources, reasons for involvement and noninvolvement in research, and factors preventing and facilitating study participation. The Dutch survey responses were examined and compared with the global survey results.
The survey was filled by 525 persons with HDRisk and PreHD. We found that the Dutch survey respondents (DSR, n=87) relied more on their family and on television to get research information than the global survey respondents (GSR, n=438). Overall, the reasons and factors enabling study involvement were less important for the DSR than the GSR. The need to travel to the study site and invasive procedures were greater obstacles to participation for the DSR than the GSR. Importantly, the information and support provided by others had a reduced influence on the DSR study engagement compared to GSR. Lastly, negative emotions were less important obstacles to DSR research participation.
The Dutch survey responses generally met the global survey results. The DSR show high motivation to take part in studies, despite having limited research experience and knowledge. This motivation is affected by tangible factors such as site distance and procedure invasiveness, but not care burden, suggesting that the DSR consider their formal/informal healthcare assistance model to be effective. Notably, the DSR motivation is less influenced by external factors and emotional status compared to GSR, suggesting that the Dutch HDRisk and PreHD communities present an intrinsic motivation to participate in research that may be enhanced through family education and multimedia campaigns.
