The instrument used to measure attitude towards using DLMs
reflected an instrumental as well as an affective or experiential
dimension (Ajzen, 2010; Fishbein & Ajzen, 2010). Three bipolar
items (valuable–worthless, meaningful–meaningless, and useless–
useful) were used to assess the instrumental dimension and
three other items (boring–fun, dull–exciting, and fantastic–horrible)
to gauge the affective dimension
