This study examines the psychometric properties of a scale of daily stress in the school context (EECE). The factorial structure and internal consistency were studied in a sample of Chilean children and adolescents from the Maule region (n = 734) between 10 to 17 years old. The factorial structure of three factors was simple and coherent with the main dimensions of the school context that can become stressful for students: academic stress, relationship stress and inadequate school climate. The internal consistency was good for both the overall scale as well as for the three factors. Also, significant differences were found in the perception of stress according to sex (male / female) and geographic location (rural /urban). These findings are consistent with the existing literature. / Se evaluaron las propiedades psicométricas de una escala de estrés cotidiano en el contexto escolar (EECE). Se estudió la estructura factorial y la consistencia interna en una muestra de niños y adolescentes chilenos de la Región del Maule (n = 734) con edades entre 10 y 17 años. La solución factorial de tres factores resultó simple y coherente respecto a las principales dimensiones del contexto escolar que pueden llegar a ser estresantes para los estudiantes: estrés académico, estrés relacional y ambiente escolar inadecuado. Los índices de consisten- cia interna fueron buenos tanto para la escala general como para los tres factores. Además se aprecian diferencias significativas en la percepción de estrés según el sexo (hombre/mujer) y ubicación geográfica (rural/urbano), que son coherentes con lo que señala la literatura.

A theory of off-job reactivity to daily work stress which encompasses the prediction of levels of reactivity from specific daily occupational stressors and personality traits, and outcomes of state and trait off-job reactivity, is presented and empirically tested. Despite decades of research linking negative spillover to maladaptive work and non-work outcomes, multidimensional studies of manifestations of spillover are rare. While investigators have increasingly recognized that spillover correlates tend to be associated with greater off-job physiological stress responses (Meijman, Mulder, Van Dormolen,&Cremer, 1992), no attempt has been made to incorporate off-job reactivity to daily stress within a multidimensional framework of negative work to non-work spillover. The overarching goal of this dissertation is to develop a model of off-job reactivity to daily occupational stress, comprising cognitive, affective, and behavioral indicators of negative work to non-work spillover. An empirical study is presented in which 75 nurses (N = 75) reported their exposure to different categories of daily work stress and provided measurements of off-job reactivity and anticipated outcomes during their off-job time for four work days. Select personality traits, work characteristics, and trait-level outcome variables were measured via an at-home questionnaire prior to the daily survey period. Empirical validation was obtained for a three-facet, higher-order factor model of off-job reactivity. Negative interpersonal interactions and situational constraints were supported as daily stressor predictors of state off-job reactivity, while trait negative affect and abusive supervision were supported as predictors of this state-level outcome. Elevated off-job reactivity was associated with several maladaptive outcomes, including diminished subjective well-being, elevated work to non-work conflict, greater somatic complaint frequency, and reduced off-job recovery activity pursuit. Implications of these findings for theoretical models of work - non-work relationships, the relative contribution of predictors and outcomes of off-job reactivity, and practical applications of the results of this dissertation are discussed.
