The Social Media Research Network was co-founded by Chantelle Roulston and Akash Shroff in August 2021 with the support of Dr. Jessica Schleider and the Lab for Scalable Mental Health (LSMH). Since 2018, LSMH has been recruiting adolescents and parents using social media—primarily Facebook and Instagram. As of September 2021, our social media presence has reached 1.4 million people across the world. More than 35,000 individuals have interacted with our posts and messages and more than 6,000 youth, young adults, and parents have completed our single-session interventions. We wanted to share our current success and improve our processes by forming a collaboration of psychology/adolescent development research labs.The SMRN Social Media Toolkit is designed to consolidate social media experiences and suggestions from various labs into a useful document for others to use. This is by no means an exhaustive list of social media platforms and suggestions. We have limited the toolkit to include the use of Facebook and Instagram, owned and trademarked by Meta Platforms, Inc.. Instagram and Facebook encompass a very large audience (diverse in age, location, and race/ethnicity). The platforms have a lot of overlap and have been successful in research efforts for the authors. This toolkit outlines broad concepts of branding, post design, and post management. It also provides details, suggestions, and tips on how to create an account, gain a following, increase engagement, and more on both Facebook and Instagram. . Lastly, it details the process of using paid Facebook and Instagram advertisements for research purposes (i.e., recruiting participants).The ultimate goal of SMRN is to increase collaboration across research groups so that we can leverage the entire network’s social media presence to improve recruitment, science communication, and outreach efforts for all research groups involved. We hope this document will serve as a preliminary guide for the research groups within the network.
