Probably but the use and interpretation of blinding indexes is still a bit controversial. For example, the 2001 CONSORT guidelines suggested using and reporting a blinding index but the latest 2010 version dropped it, saying:

Item 11 (blinding)—We added the specification of how blinding was done and, if relevant, a description of the similarity of interventions and procedures. We also eliminated text on “how the success of blinding (masking) was assessed” because of a lack of empirical evidence supporting the practice, as well as theoretical concerns about the validity of any such assessment (23, 24).
