RESUMEN Objetivos a. Adaptar y validar el "Perfil de Estrés" para la población mexicana; b. Determinar la proporción de varianza que el instrumento es capaz de explicar de los datos originales a partir de un modelo factorial; c. Agrupar las variables en los factores en donde saturan con mayor claridad; d. Evaluar la validez de contenido del instrumento, y; e. Evaluar la consistencia interna del instrumento. Método La muestra de validación estuvo compuesta por 883 participantes, 58.3% mujeres y 41.7% hombres, con edades entre 15 y 76 años (M=21.40, DE=10.02). Para verificar la validez psicométrica de la escala se llevaron a cabo el procedimiento propuesto por Reyes-Lagunes y García-Barragán (2008), el cual consta de los siguientes pasos: a. Frecuencia incluyendo sesgo para la selección de reactivos; b. Discriminación de reactivos para grupos extremos con base en el cual se eliminarán los que no cumplen con el requisito; c.

ABSTRACT Objectives This work sees to a) adapt and validate the "Stress profile" for the Mexican population, b) determine the proportion of variance that the instrument is able to explain based on the original data of a factorial model, c) group the variables into factors where they saturate most clearly, d) evaluate the validity of the content of the instrument, and e) evaluate the internal consistency of the instrument. Methods The validation sample consisted of 883 participants, 58.3% women and 41.7% men, aged between 15 and 76 years (M=21.40, SD=10.02). To verify the psychometric validity of the scale, the procedure proposed by Reyes-Lagunes and García-Barragán (2008) was used. It consists of the following steps: a) frequency, including bias for the selection of reagents; b) discrimination of reagents for extreme groups, having in mind that those that do not comply with the requirement will be eliminated; c) internal reliability; and d) validity. Results The "Stress Profile" has adequate psychometric characteristics for the Mexican population (Cronbach's alpha of 0.65 to 0.93). Conclusion The "Stress Profile" was adapted and validated for the Mexican population. This is a useful tool for studies that aim to evaluate the factors associated with stress in general, including health habits, coping styles and psychological well-being.(AU)

RESUMO
AIM: The aim of this investigation was to measure the impact of a self-administered hypnosis intervention on resilience and the inflammatory cytokine IL-6. METHOD: Over a period of 12 weeks, 11 participants listened to a self-administered hypnosis stress reduction program designed to recondition and improve participants' emotional and physical reactions to perceived work and life stressors. Subjects were administered subjective measures of coping, resilience, and stress tolerance, as well as, IL-6, an objective blood measure of inflammatory activity. RESULTS: After 12 weeks, participants were observed to have a significantly lower IL-6 serum level from baseline. Further, participants reported a significant decrease in the use of negative appraisal coping (such as, self-deprecating statements, perfectionism, and catastrophic and pessimistic thinking), and an improvement in eating/nutritional habits following the intervention. Baseline eating/nutritional habits and threat minimization coping significantly predicted a change in serum IL-6 over the course of the intervention in stepwise hierarchical regression analyses. CONCLUSION: Pilot study provides support that a brief self-administered CD hypnosis stress reduction program can modify a physiological measure of inflammation (IL-6), and improve coping and resilience in the face of work and life stress.
