La the orie de la pre servation des ressources (COR pre suppose que la perte d'une ressource est la principale composante du processus de stress. Un gain en ressources, par contre, est pre sente comme e tant d'importance croissante dans un contexte de perte. Parce que les ressources sont aussi utilise es pour contrecarrer une perte de ressources, les gens sont, aÁ chaque phase du processus de stress, de plus en plus vulne rables aux se quelles du stress ne gatif, cela si la succession des e veÁ nements de bouche sur une spirale de pertes rapides et douloureuses. La the orie COR est percË ue comme e tant une alternative aux the ories du stress base sur l'e valuation parce qu'elle repose davantage sur la nature objective et culturellement interpre te e de l'environnement dans la de termination du processus de stress, plutoà t que sur l'analyse personnelle de l'individu. La the orie COR a pre dit avec succeÁ s un ensemble de donne es lie es au stress dans des situations organisationnelles, dans le domaine de la sante , dans les suites du stress traumatique et dans la gestion du stress quotidien. Des avance es re centes dans la compre hension des fondements biologique, cognitif et social des re ponses de stress se sont re ve le es cohe rentes avec la formulation originelle de la the orie COR, mais suggeÁ rent qu'il faudrait appre hender cette the orie et le processus de stress d'une facË on plus collective que ce ne fut d'abord le cas. On traite aussi du roà le des gains et pertes de ressources dans le pronostic des conse quences positives du stress. On discute enfin des limites et des applications de la the orie COR.Conservation of Resources (COR) theory predicts that resource loss is the principal ingredient in the stress process. Resource gain, in turn, is depicted as of increasing importance in the context of loss. Because resources are also used to prevent resource loss, at each stage of the stress process people are

Psychology has increasingly turned to the study of psychosocial resources in the examination of well-being. How resources are being studied and resource models that have been proffered are considered, and an attempt is made to examine elements that bridge across models. As resource models span health, community, cognitive, and clinical psychology, the question is raised of whether there is overuse of the resource metaphor or whether there exists some underlying principles that can be gleaned and incorporated to advance research. The contribution of resources for understanding multicultural and pan-historical adaptation in the face of challenge is considered.

Conservation of resources (COR) theory is a stress and motivational theory that has been applied broadly in the organizational literature. Increasingly, this literature is transforming from a focus on resource‐setting fit to an understanding that ‘fitting’ is an active process that operates dynamically with both individuals and settings altering and metamorphosing. COR theory provides a framework to understand, predict, and examine this transactional relationship that can then be used to shape settings towards more optimal balance of resource cost and benefit. Rather than focusing on single, isolated variables or seeing individuals and settings as independent agents, COR theory suggests that resources exist in caravans. Therefore, employers that hope to ensure employee engagement must maximize the ecology that fosters resource caravan enrichment and challenge that promotes excellence, dedication, and commitment.
