It is a peer reviewed article. I found it on a pop-up right below the title of the article TTT linked.

What are journal pre-proofs?
Journal pre-proofs are Articles in Press that have been peer reviewed and accepted for publication by the Editorial Board of this publication. They have undergone enhancements after acceptance, such as the addition of a cover page and metadata, and formatting for readability, but are not yet definitive versions of record. These versions will undergo additional copyediting, typesetting and review, and may not yet have full ScienceDirect functionality. For example, supplementary files may still need to be added, links to references may not resolve yet, etc. The text could still change before final publication.
