Response Difficulty

This four item, seven point scale is intended to measure the perceived cognitive effort involved in answering a question. The scale was referred to by a variety of names: the effort index by Menon, Raghubir, and Schwarz (1995), the accessibility manipulation by Raghubir and Menon (1998), the cognitive effort index by Menon, Block, and Ramanathan (2002), and the difficulty index by Menon and Raghubir (2003).
