Facebook recruitment of nurses as research participants: Methodological considerations

Social Media Use for Research Participant Recruitment: Integrative Literature Review

BACKGROUND

Social media tools have provided health researchers with the opportunity to engage with communities and groups in a nonconventional manner to recruit participants for health research. Using social media to advertise research opportunities and recruit participants facilitates accessibility to participants from broad geographical areas and diverse populations. However, little guidance is provided by ethics review boards for researchers to effectively use this recruitment method in their research.

OBJECTIVE

This study sought to explore the literature on the use of social media for participant recruitment for research studies and identify the best practices for recruiting participants using this method.

METHODS

An integrative review approach was used to synthesize the literature. A total of 5 health sciences databases, namely, EMBASE (Ovid), MEDLINE (Ovid and EBSCOhost), PsycINFO (Ovid), Scopus (Elsevier), and CINAHL Plus with Full Text (EBSCOhost), were searched using predefined keywords and inclusion and exclusion criteria. The initial search was conducted in October 2020 and was updated in February 2022. Descriptive and content analyses were applied to synthesize the results, and the findings are presented in a narrative and tabular format.

RESULTS

A total of 96 records were included in this review, 83 (86%) from the initial search and 13 (14%) from the updated search. The publication year ranged between 2011 and 2022, with most publications (63/96, 66%) being from the United States. Regarding recruitment strategy, 45% (43/96) of the studies exclusively used social media, whereas 51% (49/96) used social media in conjunction with other strategies. The remaining 4% (4/96) provided guidelines and recommendations for social media recruitment. Notably, 38% (36/96) of these studies involved hard-to-reach populations. The findings also revealed that the use of social media is a cost-effective and efficient strategy for recruiting research participants. Despite the expanded use across different populations, there is limited participation of older adults in social media recruitment.

CONCLUSIONS

This review provides important insights into the current use of social media for health research participant recruitment. Ethics boards and research support services in academic institutions are encouraged to explicitly provide researchers with guidelines on the use of social media for health research participant recruitment. A preliminary guideline prepared based on the findings of this review is proposed to spark further development in this area.

Facebook recruitment for research of children and parents during the COVID-19 pandemic

The COVID-19 pandemic has created unique challenges for recruitment of adults and children into clinical research. The sudden onset of stay-at-home orders and social distancing enacted in much of the United States created sudden barriers for researchers to recruit participants in-person. Recognizing the critical need to understand the impact of COVID-19 on children and families in real time, studies required an alternative approach. The present study sought to develop methods and establish the feasibility of utilizing Facebook's targeted advertising to enroll schoolaged children and their parents for a study examining the impact of the COVID-19 pandemic on families.

This study used an 8 week pay-per-click advertisement approach via Facebook for research recruitment. Parents of children age 8 to 17 were invited and asked to include their child. Standardized measures were included for parents and children. Zip code targeting was used to increase diversity in participants.

The ad campaign reached 213,120, yielding 3563 clicks, 684 parent participants, 494 child participants and a 26% conversion rate over eight weeks. The cost-per-click was $0.64, and cost-per-participant was $3.30 and $4.60 for parents and children, respectively.

This nationwide study successfully used social media to recruit a robust nationwide sample of parent-child dyads during the COVID-19 pandemic. Social media recruitment mitigated typical time and engagement barriers for participants while also circumventing social and physical distancing orders due to the pandemic which allowed for real time assessment of the pandemic's effects on families. Future consideration should be given.to social media as a research recruitment methodology.
