Positive psychology is a relatively new branch of psychology which emphasizes positive and adaptive characteristics of the individual instead of focusing solely on deficits and limitations (Seligman & Csikszentmihalyi, 2000). According to Seligman and Csikszentmihalyi (2000), positive psychology is "about valued subjective experiences; well-being, contentment, and satisfaction (in the past); hope and optimism (for the future); and flow and happiness (in the present)" (p. 5). Although positive psychology, as a discipline, developed relatively recently, this asset-oriented approach to understanding the human experience is not new to the field of rehabilitation. The core values inherent in rehabilitation philosophy emphasize that the strengths of persons with disabilities (PWDs) should be highlighted, supported, and developed, whereas their limitations should be accommodated and de-emphasized (Dunn & Dougherty, 2005;Maki & Murray, 1995). As such, a primary goal of rehabilitation research is to identify and examine factors that contribute to an individual's sense of well-being that may be targeted for intervention .Historically, rehabilitation research has focused on a variety of positive contributors to well-being in PWDs, such as coping skills, self-esteem, and social support. However, recent research suggests that a new, global, higher-order construct may be a more important contributor to a person's well-being than domain-level indicators (Judge, Locke, & Durham, 1997). This construct, "core self-evaluations" (CSE) is conceptualized as the overall, fundamental judgment that individuals have about how worthy or competent they are as people (Judge, Locke, Durham, & Kluger, 1998). According to CSE theory, this overarching variable is comprised of four domain-level traits. These include self-esteem (i.e., a person's judgment of his or her self-worth; Rosenberg, 1965), generalized selfefficacy (i.e., a person's evaluation of his or her ability to successfully complete a wide range of tasks; Bandura, 1977), emotional stability or low neuroticism (i.e., the tendency for a person to feel calm and secure; Eysenck, 1990), and locus of control (i.e., the belief that a person has direct control over events in his or her life, as opposed to fate or powerful other being in control; Rotter, 1966). Judge and colleagues (Judge et al., 1997;Judge et al., 1998) purport that these four characteristics combine to explain 554608R CBXXX10.
