“…They have been constructed to measure the composite construct of self-efficacy for science (Aydin & Uzuntiryaki, 2009; Dalgety, Coll, & Jones, 2003), mathematics (Betz & Hackett, 1983), and writing (Pajares, 2007). Scales also have been created to measure the four sources of self-efficacy for academics (Usher & Pajares, 2006), mathematics (Lent, Lopez, & Bieschke, 1991; Lopez & Lent, 1992; Matsui, Matsui, & Ohnishi, 1990; Usher & Pajares, 2009), jazz music performance (Wehr-Flowers, 2007), and orchestra performance (Hendricks, 2009). The MPSES was designed to measure these same sources of self-efficacy for music performance among band, chorus, and string orchestra students at the secondary school level (i.e., Grades 6 to 12, or approximate ages 11 to 18).…”
