“…Among 42 items, eight items asked about their perceived competence in reading and interest in and enjoyment of reading (Marsh, 1990;Marsh et al, 1984;Tourangeau et al, 2009): "I get good grades in reading," "Work in reading is easy for me," "I am good at reading," "I like reading," "I am interested in reading," "I cannot wait to read each day," "I like reading long chapter books," and "I enjoy doing work in reading" (National Center for Education Statistics, 2010). The SDQ has been used to assess reading motivation (e.g., Froiland & Oros, 2014;Karasinski & Anderson, 2017). Specifically, the first three items appear to be closely related to reading self-efficacy (i.e., the belief that one can be successful at reading), whereas the remaining five items measure intrinsic motivation for reading (i.e., willingness to read for the sake of internal purposes of reading), which are two important dimensions of reading motivation recurring in reading research (Schiefele et al, 2012;Wigfield & Guthrie, 1997).…”
