This study analyzes the factorial structure, internal consistency and factorial invariance according to gender of the Lasher and Faulkender Anxiety about Aging Scale. The sample consisted of 706 Mexican adults. The factor structure of the questionnaire was analyzed with confirmatory factor analysis. The analyses show a four-factor structure (fear of the elderly, psychological concerns, physical appearance and fear of loss) is viable and adequate for both the total sample (GFI .979; RMSEA .037; CFI .987) as for women (GFI .970; RMSEA .045; CFI .980) and men (GFI .919 and RMSEA .080; CFI .947). The four-factor structure, based on statistical and substantive criteria, has shown adequate reliability and validity fit indicators and can be considered a short and computerized version of the original version by Lasher and Faulkender. On the other hand, the factor structure, the factor loadings and the intercepts are considered invariant in the two populations studied (men and women); however, there are differences between the populations on the means of the physical appearance and fear of loss factors  a1134-7937  a2174-0437
