Researchers who seek to better understand this complex interpersonal phenomenon, must negotiate a traumatised and, sometimes, reluctant population who may be loath to revisit their distressing experiences of bullying or emotional abuse for the purposes of academic research. While acknowledging that researching sensitive topics present complex ethical, moral and practical difficulties (Coen & Arieli, 2011; Fahie, 2014; Einarsdottir, this issue), there is a consequential professional imperative that such studies are subject to systematic, rigorous and thorough methodological approaches. For those engaged in qualitative research on workplace bullying or harassment, the successful realisation of a ‘good’ sample – in terms of size and composition - remains a critical tension (Fahie and Devine, 2014; Fahie 2016). Similarly, traditional quantitative researchers must also anticipate and, indeed, successfully resolve, complex ethical and methodological dilemmas in order to ensure a scientifically appropriate response rate (Creswell, 2014, Fugard and Potts, 2015, Osborne, 2008). This chapter will examine these key methodological tensions for both quantitative and qualitative researchers, focusing specifically on accessing, recruiting and retaining an appropriate research population. The chapter concludes with some practical suggestions/advice for the researcher-in-the-field which draw upon the real-world experience of both authors.enThe final publication is available at Springer via http://dx.doi.org/10.1007/978-981-10-5334-4_19-1Qualitative researchQuantitative researchWorkplace bullyingResearch methodologiesSamplingSensitive researchBook Chapter10.1007/978-981-10-5334-4_19-12018-08-23https://creativecommons.org/licenses/by-nc-nd/3.0/ie/
