Social media use is on the rise. With a 10-fold increase in use over the last decade, it is estimated that over 69% of adults now use social media on a regular basis. Social media has been identified as a key resource for health professionals, including psychologists, to learn new knowledge, interact with others, keep up-to-date on the latest research, and get tips on how to integrate evidence-based information into their clinical practice. The objectives of this article are to (a) summarize professional opportunities in the area of social media and outline the various ways that pediatric psychologists can use social media in their research, practice, and advocacy; and (b) provide practical suggestions for pediatric psychologists on creating, sharing and interacting over social media. Recommendations for participating in activities such as live tweeting, video streaming, and social media evaluation are discussed. Common barriers, potential pitfalls, and ethical issues associated with use of social media by pediatric psychologists are also addressed.
