2.1. Data sources and search strategy
Two searches were conducted using the databases Medline,
PsycInfo, Cinahl, Scopus, Web of Science, and Cochrane. The first
searched for articles published until March 2015, and the second search
was to update for articles published until March 2016. The search strategy
employed a combination of search terms including Internet (or online,
web, e-health, computer) and CBT (or behavior, cognitive, therapy,
treatment) and was limited to an age range from 0 to 18 years. The complete
search strings can be viewed in Supplement 1.
