The number of words was used to measure the level of CSR
for several reasons. Measuring the number of words is more detailed than
measuring “part-page” disclosure (Deegan and Gordon, 1996); words lend
themselves to more exclusive analysis (Gray et al., 1995b); “part-page” disclosure
does not consider different print and page sizes (Hackston and Milne, 1996); and
measurement according to number of sentences ignores differences in typeface size
and does not account for different grammar conveying the same message (Milne
and Adler, 1999).
