You can't always trust an article database on whether or not a particular journal is peer-reviewed. To find out whether it is or not, you can:
a) Search the journal title in the UlrichsWeb database
Ulrichsweb is a bibliographic database providing detailed, comprehensive, and authoritative information on serials published throughout the world. It covers all subjects, and includes publications that are published regularly or irregularly and are circulated free of charge or by paid subscription.
b) Search the journal title in Google or another search engine
