<p>The main objective of the study was to determine the construct, convergent, and discriminant validity of a new scale of patience. It was used an incidental sample of 289 college students (48.10% men, 51.90% women). It was used confirmatory factor analysis (CFA), the average variance explained (AVE), r of Pearson, and the formula to calculate the explained common variance (ECV) to know about the scale one-dimensionality. It is found a one-dimensional scale having four items with an excellent goodness of fit and acceptable reliability: p = .430; X²/df = .844; NFI = .993; NNFI = 1.004; GFI = .997; AGFI = .985; CFI = 1.000; RMSEA = .0001, and SRMR = .0151; ɑ = .73 and ω = .73. It has convergent validity with the Three-Factor Patient Questionnaire (3-FPQ; r = .45 [CI90%, .38-.70], d = small). It shows discriminant validity with the Anger Proneness Scale-G (APS-G; r = -.26 [CI90%, -.15, -.54], d = small). It concludes that the new Brief Patience Scale-G (BPS-G) has good psychometric properties as to recommend its use in Mexico for research purposes.</p>
