Given the word-for-word reproduction of the 28 item- pool,
an argument could be made that the COSS plagiarizes the Bsas, even though the authors acknowledge the source of their scale items.
In 2015, I along with my colleagues, developed and subsequently published(in the journal Frontiers in Psychology) a new scale to assess shopping addiction-
the 7-item Bergen Shopping Addiction Scale(Bsas) which I wrote about in one of my previous blogs.
However, the purpose of this sentence was to give fellow researchers permission to use the validated scale in their own studies and
to avoid the inconvenience of having to request permission to use the Bsas and then waiting for an answer.
