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.
