Personal relative deprivation is a negative social comparison process typified by self-com- parison, negative appraisal, and resultant negative emotionality. Personal relative depriva- tion has been associated with poorer physical and mental health in several domains. It has been hypothesized that the deprivation-health link operates through a stress pathway. Stress has been specifically implicated in the onset and maintenance of functional disor- ders, including fibromyalgia and functional gastrointestinal disorders. Despite the theoretical links between personal deprivation, stress, and functional disorders, researchers have not assessed relationships between these variables.
