Communicating individual human biomonitoring results to study participants has been the subject of debate for some time. This debate is dominated by ethical considerations from a researchers' perspective on whether or not to communicate, thereby overlooking more practice-based questions from a participants' perspective on what and how to communicate. We conducted a small scale follow-up study based on eleven face-to-face interviews with mothers participating in the third cycle of the Flemish Environment and Health Study (FLEHS III 2012-2015) to investigate how they experienced and interpreted individual biomonitoring results. Key findings indicate that respondents were generally satisfied with participating in the biomonitoring study, but the report-back process especially lacked contextualized information and interactive communication options to better comprehend and cope with personal results. These findings also argue in favor of a more tailored approach in which report-back methods, formats and content are diversified according to the type of results and the preferences of participants. A reflexive research practice with active engagement in follow-up research is crucial to improve participants' understanding and use of personal biomonitoring results. ; Morrens, B (corresponding author), Univ Antwerp, Fac Social Sci, B-2000 Antwerp, Belgium. bert.morrens@uantwerpen.be; hans.jonker@uantwerpen.be; elly.denhond@provincieantwerpen.be; dries.coertjens@uantwerpen.be; ann.colles@vito.be; greet.schoeters@vito.be; nicolas.vanlarebeke@ugent.be; tim.nawrot@uhasselt.be; adrian.covaci@uantwerpen.be; vera.nelen@provincieantwerpen.be; frederic.vandermoere@uantwerpen.be; ilse.loots@uantwerpen.be
