Objective. To examine the factor structure of the 4-and 10-item Perceived Stress Scale (PSS) among 1 310 Mexican women participating in a prospective cancer cohort study. Materials and methods. We performed exploratory and confirmatory factor analyses in two sub-samples of the Mexican Teachers' Cohort. We evaluated internal consistency, estimated the correlation between PSS-4 and PSS-10, and assessed their correlation with a depressive symptoms scale. Results. Two-factor models were the solutions with the best fit to the data for both PSS-4 and -10, exhibiting strong factor loadings (0.39 to 0.75) and high internal consistency (Cronbach's alpha 0.72 and 0.83). The correlation between PSS-4 and PSS-10 was r=0.91 and the correlations of these two scales with a depressive symptoms scale were r=0.41 and r=0.46, respectively. Conclusions. PSS might be an adequate scale to assess perceived stress in this prospective cancer cohort study. PSS-4 may be advantageous due to its simplicity, low cost, and short application time in multicountry studies on stress and cancer. [ABSTRACT FROM AUTHOR] |

Objetivo. Evaluar la estructura factorial de la Escala de Estrés Percibido (PSS, por sus siglas en inglés) de 4 y 10 ítems en 1 310 mujeres mexicanas que participan en un estudio de cohorte sobre cáncer. Material y métodos. Se realizó análisis factorial exploratorio y confirmatorio en dos submuestras distintas del estudio ESMaestras. También se evaluó la consistencia interna, la correlación entre la PSS-4 y la PSS-10, y la correlación de estas escalas con una escala de síntomas depresivos. Resultados. El modelo de dos factores fue la solución con los mejores índices para ambas escalas, exhibiendo cargas factoriales fuertes (0.39-0.75), y alta consistencia interna (alfa de Cronbach=0.72 y 0.83). La correlación entre la PSS-4 y la PSS-10 fue r=0.91 y la correlación de estas escalas con la escala de síntomas depresivos fue r=0.41 y 0.46. Conclusiones. La PSS es una escala adecuada para evaluar el estrés percibido en este estudio de cohorte sobre cáncer. La PSS-4 puede ser ventajosa por su simplicidad, bajo costo y corto tiempo de aplicación en estudios multipaís sobre estrés y cáncer. [ABSTRACT FROM AUTHOR] |
