The authors of this manuscript completed a doctoral program in public health within the past 5 years. As part of the doctoral program, the authors were required to collect primary data while conducting dissertation research. In this manuscript, the authors share the identified challenges encountered during the data collection process of conducting dissertation research. Data collection is the first stage in the research process. Depending on the data collection method, researchers could encounter challenges with obtaining information from participants in a study. Although knowledgeable about data collection methods, theory, tips, and challenges, the authors encountered unanticipated real time situations that served as challenges. The authors also share recommendations to streamline the data collection process in an effort to inform doctoral students and early career professionals engaged in data collection. Limited information on the challenges of data collection is available in the public health and social research literature. A search of the literature on the topics of data collection challenges encountered by early career researchers yielded few studies (Ashton, 2014; Dearnley, 2005; Nicholl, 2010). Based on the dearth of studies in the literature, there is a need to share and report the data collection challenges of public health doctoral students. This knowledge can assist doctoral students and early career researchers when facing data collection challenges in the future. This topic is helpful and relevant given that many doctoral students collect data on limited budgets. The primary purpose of this manuscript is to describe data collection challenges encountered by public health doctoral students. The secondary purpose is to provide recommendations to doctoral students and early career researchers on strategies to address these identified data collection challenges. Data collection is the first stage in the research process. Data collection, usually occurring simultaneously with data analysis in qualitative research, is defined as the systematic gathering of data for a particular purpose from various sources, including, interviews, focus groups, observation, existing records, and electronic devices. Depending on the data collection method, researchers could encounter challenges with obtaining information from participants in a study. Early career researchers including doctoral students may face unanticipated challenges during the data collection phase of their dissertation research for numerous reasons. The challenges encountered during the data collection process can involve research with human subjects related to interviews or focus groups. Literature Review Our search of data collection challenges in the literature were organized into the following categories: 1) researcher, 2) participant, 3) data collection environment, and 4) interview guide design. Manuscripts were found in the nursing, public health, social science, and methodology literature (Bonevski et al., 2014; Bournet & Robson, 2015; Dearnley, 2005; Easton, McComish, & Greenberg, 2000; Hebert, Loxton, Bateson, Weisberg, & Locke, 2013; Johnson & Clarke, 2003). First, the authors identified data collection challenges related to the researcher. Data collection challenges have included: 1) participants who were resistant to participate; 2) how to dress for an interview, such as wearing formal or informal clothes; 3) lack of experience conducting qualitative interviews; and 4) feelings of isolation from peers and other researchers during data collection (Dearnley, 2005; Hoskins & White, 2013; Johnson & Clarke, 2003). Novice researchers may have difficulty establishing rapport with participants unlike them and encounter participants who are resistant to participate in the interview (Hoskins & White, 2013). …
