a b s t r a c tBased upon the revised Job Demands and Resources Model (2008) we aim first, to test the relations between work-family conflict and emotional exhaustion across time and second, to determine the role of professional self-efficacy in this relation. A longitudinal study was conducted in two times, with a year of interval in a Spanish Army sample (n = 242). To test the causal relations between work-family and emotional exhaustion three models are tested: normal causal, reversed causal, and causal reciprocal. To test the role of professional self-efficacy in the relation between work-family conflict and emotional exhaustion four alternative models are tested: independence, antecedent, mediation, and independence plus antecedent models. Structural Equation Modeling results confirm the simultaneous reciprocal effects model as it fits the data better than the normal causal or the reverse causal models. This result suggests a spiral process, where work-family conflict predicts emotional exhaustion and at the same time emotional exhaustion increases work-family conflict. Likewise, this article contributes to clarifying the role of selfefficacy in the complex relationship between work-family conflict and emotional exhaustion.

Changes in the education system in Ecuador have increased the workload of university teachers, producing stress and burnout. This study analyses the relation between work overload, coping styles and emotional exhaustion in a sample of 202 university teachers by using a hierarchical regression model analysis. The results show that work overload and evasive coping are positively related to emotional exhaustion, while active coping is negatively related to emotional exhaustion. Evasive coping moderated the relationship between work overload and emotional exhaustion so that teachers who use more evasive coping in situations of high work overload experience less burnout than teachers who use this coping style less. Finally, we discuss the limitations of this study and its theoretical and practical contributions for university professors in Latin American contexts.

Purpose -To analyse the influence of three different types of organisational support (supervisor's and colleagues' support, training, and acknowledgement and rewards) on the implementation of teamwork systems. Design/methodology/approach -Main and buffer effects of social support were tested using different subjective (job satisfaction and job involvement) and objective (production and total production management (TPM)) organisational criteria. In the longitudinal study, two sets of data were taken from a sample of workers from car-manufacturing factories in two consecutive years. Findings -The three dimensions of support explain 30 per cent of the variance in job satisfaction in time 1(T1) and 11 per cent in time 2 (T2). A total of 50 per cent of job involvement in T1 is due to the supervisor's and colleagues' support, whereas in T2 this influence is not apparent. Social support from supervisor's and colleagues and acknowledgment and rewards explain 10 per cent of the variance of the objective measures (production and TPM).Research limitations/implications -The objective measures used are similar for the production line as a whole and therefore they do not consider the possible differences in performance between different production line groups. Practical implications -The importance of social support in organisational settings, in particular in the implementation of working teams. It also emphasises the need to distinguish the different stages of support from colleagues, supervisors or the organisation. Originality/value -This study indicates that support is an easy and inexpensive means not only to improve the social environment of an employee but also to make an important contribution towards productivity targets.

Despite the amount of research on family-work conflict and burnout, there persist questions about their relations and which coping strategies are the most effective. In this paper we address this issue from a gender perspective with a sample of 131 dual-earner couples developing both individual and couple analyses. The results at individual level yield gender differences when each of the two burnout components is explained. The main predictor of emotional exhaustion is workfamily conflict while family-work conflict is the main predictor of depersonalization, especially for men. Regarding coping strategies, behavioural coping is negatively related to male depersonalization. However, behavioral and emotional coping increases both burnout dimensions in women, particularly if family-work conflict is high. At couple level, findings confirm the relationship between conflicts and burnout and the moderating role of behavioural coping to explain emotional exhaustion.

Título: Lidiando con el burnout: Análisis de relaciones lineales, no lineales y de interacción. Resumen: Este estudio analiza la relación entre el afrontamiento centrado en la acción y en la emoción y las dimensiones del burnout (agotamiento emocional, cinismo y realización personal) comparando los modelos lineal, no-lineal y de interacción mediante análisis de regresión cuadrática. La muestra consistió en 202 profesores de universidad. Variables como el sexo o la edad no resultaron significativas al explicar la relación entre el afrontamiento y el burnout. Los resultados muestran relaciones significativas negativas entre el afrontamiento centrado en la emoción y el agotamiento y cinismo y positivas con la realización personal (modelo lineal). También muestran que niveles muy bajos o muy altos de afrontamiento centrado en la emoción disminuyen la realización personal de forma significativa (modelo no-lineal), y que el efecto combinado de estrategias de afrontamiento es significativo, de forma que cuando el uso de las estrategias enfocadas en la emoción es mayor que el de las enfocadas en la acción, el agotamiento aumenta y la realización personal disminuye. Estos resultados apoyan la idea de que para comprender la naturaleza flexible y adaptativa del afrontamiento y de que éste opera en un proceso combinado donde unas estrategias afectan a las otras, es de gran utilidad la aplicación de modelos nolineales y de interacción. Finalmente, se discuten las implicaciones prácti-cas para futuras investigaciones y para los programas de prevención y de intervención sobre el burnout. Palabras clave: Afrontamiento enfocado en la acción; afrontamiento enfocado en la emoción; burnout; relación lineal; relación no lineal; efecto de interacción.Abstract: This study analyzes the relationship between action-focused coping, emotion-focused coping and burnout dimensions (emotional exhaustion, cynicism and personal accomplishment) by comparing linear, non-linear and interaction models using quadratic regression analysis. The sample consisted of 202 college professors. Variables such as gender or age were not significant when explaining the relationship between coping and burnout. The results show significant negative relationships between emotion-focused coping and exhaustion and cynicism, and positive relationships with personal accomplishment (linear model). They also show that very low or very high levels of emotion-focused coping diminish personal accomplishment significantly (non-linear model), and that the combined effect of strategies is significant, so that when the use of emotion-focused coping is greater than the use of action-focused coping, exhaustion increases and personal accomplishment decreases. These results support the idea that in order to better understand the flexible and adaptive nature of coping and that it operates in a combined process where one strategy affects the other, the application of non-linear and interaction models are very useful. Finally, we discuss the practical implications for future research ...
