Propiedades psicométricas de una escala para medir dificultades en habilidades sociales relacionadas con la victimización

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...

Zusammenfassung: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. Escopo. Estabelecer as propriedades psicométricas de uma escala para medir dificuldades nas habilidades sociais para afrontar a agressão por pares. Metodologia. Participaram 502 estudantes mexicanos de educação primária, 279 crianças masculinas (M = 10.52, DE = 1.13 años) e 223 femininas (M = 10.81, DE = 1.25 años). Foi comparado o ajuste empírico de dois modelos (unidimensional e bidimensional), e foi determinada a validez concorrente da escala ao indagar a relação de suas pontuações com reportes de vitimização. Resultados. O modelo bidimensional (vulnerabilidade e passividade) apresentou melhores indicadores de ajuste (X2 = 36.60, gl = 19, p = 0.009; X2/gl = 1.92; CFI = 0.98; AGFI = 0.96; RMSEA = 0.04 IC 90 [0.02 - 0.06]; SRMR = 0.04; AIC = 70.60) que o unidimensional (X2 = 290.42, gl =20, p = 0.000; X2/gl = 15.27; CFI = 0.48; AGFI = 0.75; RMSEA = 0.27 IC 90 [0.20 - 0.25]; SRMR = 0.16; AIC = 337.42). As dificuldades nas habilidades sociais explicam uma parte significativa da variação dos reportes de vitimização em ambos sexos (homens R2 = 0.20, f2 = 0.25; mulheres R2 = 0.24, f2 = 0.32). Conclusão. A escala
