3.3.2. Scope Index (SCI)

This metric counts the number of questions answered in a particular annual report and compares this with the maximum possible number (all questions answered). In the previous research, these were referred to as themes rather than questions. Because of the low number of questions answered in many of the early years of the sample, in particular, we also computed a second SCI index scored by categories answered. The questions were grouped into six categories (see Appendix A), and each annual report was assessed based on the number of categories where at least one question had been answered out of a potential high score of all six. We refer to the question-based SCI as SCI-Q and the category SCI as SCI-C.
