Abstract Objective We assessed the relations between the Subjective Memory Complaints Questionnaire (SMCQ) and the Spanish English Verbal Learning Test (SEVLT) for equivalence across race. Secondary objectives include evaluating the SMCQ for measurement invariance across race. Methods The current study accessed data from the University of North Texas Health Science Center’s Health and Aging Brain Study – Health Disparities (HABS-HD). We used structural equation modeling (SEM) to test the SMCQ for measurement invariance across Black (n = 515), Hispanic (n = 1104), and White (n = 1096) Americans. We first specified a configural model to assess the fit of the underlying structure across groups, followed by a scalar model to determine whether scores reflect comparable levels of the latent construct. Next, we regressed the SEVLT on the SMCQ to test the relation between subjective and objective memory functioning. Lastly, we specified a multigroup SEM to compare unconstrained and constrained regression models across race. Results Full scalar invariance was tenable for the SMCQ (ΔCFI = 0.007, NCI = 0.023). There were significant negative relations between the SMCQ and the SEVLT for each group (Black: b = −2.31; Hispanic: b = −1.63; White: b = −2.72), but the relations were not equivalent across groups [χ2 diff (df) = 20.2.45 (2), p
