Objective. Determine the psychometric properties of a scale to measure social skills difficulties in handling peer aggression. Method. 502 Mexican students participated in the study of which 279 were boys (M = 10.52, DE = 1.13 years) and 223 girls (M = 10.81, DE = 1.25 years). The study compared the empirical adjustment of two measurement models (one-dimensional and two-dimensional) to measure social skills difficulties associated with victimization by peers and establish evidence of concurrent validity of the scale to investigate the relationship of their scores with reports of victimization. Results. It was found that the measurement model comprised of two dimensions (vulnerability and passivity) has better indicators of adjustment (X² = 36.60, df = 19, p = 0.009; X²/df = 1.92; CFI = 0.98; AGFI = 0.96; RMSEA = 0.04 CI 90 [0.02 - 0.06]; SRMR = 0.04; AIC = 70.60) with respect to a dimension for both (X² = 290.42, df = 20, p = 0.000; X²/df = 15.27; CFI = 0.48; AGFI = 0.75; RMSEA = 0.27 CI 90 [0.20 - 0.25]; SRMR = 0,16; AIC = 337,42). The difficulties in developing social skills explain a significant part of the variance of the reports of victimization of both students (men: R² = 0.20, f²= 0.25; women: R² = 0.24, f²= 0.32). Conclusion. The scale has psychometric properties that allow its use in measuring social skills difficulties to face peer aggression.
