Measurement invariance of the Beck Depression Inventory-Second Edition across race (Blacks and Whites) was examined in a sample of university students, from two universities from diverse geographical areas of South Africa (N = 870). Multigroup confirmatory factor analysis (i.e., means and covariance structures) was used to test the factorial invariance of the hierarchical four-factor structure, composed of three first-order factors (i.e., Negative Attitude, Performance Difficulty, and Somatic Complaints) and one second-order general factor (Depression) found with South African students. Evidence of measurement invariance was established at the level of configural, metric, and scalar invariance. However, there were some evidence of differential additive response style across race-with two non-invariant intercepts (Item 5 and 14) being identified. Results also revealed significant latent mean differences favoring Black students on the Performance Difficulty and Somatic Complaints factors but not on the Negative Attitude factor. Findings suggest that the Beck Depression Inventory-Second Edition provides an assessment of the severity of depressive symptoms that is equivalent across race in university students. Downloaded from Makhubela 3 to examine the MI (i.e., configural, metric, and scalar invariance) and latent mean differences of the BDI-II across race in a South African university sample.
Method
ParticipantsA purposive sample of 870 students (M age = 21.70 years, standard deviation [SD] = 13.51, 70% female) was selected from both the University of Limpopo (46%) and the University of Pretoria (54%). The inclusion criteria were as follows: (1) undergraduate university students, (2) command of English, and (3) predominantly White university and predominantly Black university (4) race. Besides accessibility, sampling from the institutions ensured that we had a heterogeneous sample (i.e., race and socio-economic status [SES]) which also approximated the ones used in previous studies on the BDI-II (Beck, Steer, & Brown, 1996;Byrne, Stewart, & Lee, 2004). The overwhelmingly female (72%) sample, while a concern, is not surprising given the sampling strategy used and the undergraduate enrollment rates of the two South African universities. For instance, the Department of Higher Education and Training's (2011) Statistics on Post-School Education and Training in South Africa reports that female students comprise 54% of all students enrolled in contact programs at the University of Limpopo and 60% of all students enrolled in contact programs at the University of Pretoria. This part of the sample characteristics is given a detailed treatment in the Methodology section. The data consisted of undergraduate students from faculties of Humanities, Natural Sciences, Statistics, Law, and Management Sciences. In total, 67% of the participants identified themselves as 'Black', while 33% said they were 'White'. The mean score (11.45; SD = 7.74) of the sample on the total BDI-II is outside the symptomatic range of the BDI-II suggested...
