“…The independent variable was personal and academic stress level, which was measured by the Student-life Stress Inventory (SSI) (see Appendices E and F) (Gadzella, 1991). The self-report paper and pencil instrument, developed from a theoretical model described by Morris (1990) The Student-life Stress Inventory (SSI) has been used in numerous studies to measure college student stress and to determine the reliability and validity of the instrument (Gadzella, 1991(Gadzella, , 1994a(Gadzella, , 1994b(Gadzella, , 2004Gadzella & Baloglu, 2001;Gadzella & Carvalho, 2006;Gadzella, Fullwood, & Ginther, 1991;Gadzella, Fullwood, & Tomcala, 1992;Gadzella, Masten, & Stacks, 1998). For example, concurrent validities were reported for the SSI for 95 students in 1991 (Cronbach's alpha ranging from .52 for the Frustrations scale to .85 for the Changes scale), 290 students in 1994 (p = .0009), and 381 male and female students enrolled in psychology courses at all levels of a state university in 2001 (Cronbach's alpha = .92) (Gadzella, 1994b;Gadzella & Baloglu, 2001;Gadzella, Fullwood, et al, 1991).…”
