Preliminary evidence from a study using a modified Stroop paradigm suggests that individuals with chronic pain selectively attend to pain-related information. The current study was conducted in an attempt to replicate and extend this finding. Nineteen patients with chronic pain stemming from musculoskeletal injury and 22 healthy control subjects(More)
The literature indicates a substantial overlap between chronic pain and posttraumatic stress disorder (PTSD) symptoms in individuals who sustain accidental injury. To date, however, there have been no studies of PTSD symptoms in individuals who experience work-related injury. Consequently, we assessed 139 consecutive injured workers using the Modified PTSD(More)
The authors collected a series of 236 cases of multiple personality (MPD) reported to them by 203 psychiatrists, clinical psychologists and other health care professionals. MPD patients experienced extensive sexual (79.2%) and physical (74.9%) abuse as children. They had been in the health care system for an average of 6.7 years before being diagnosed with(More)
Two studies that assess fear and avoidance in patients with chronic pain are presented. In the first study, 200 patients with chronic back pain were classified, using the Multidimensional Pain Inventory (Kerns et al., 1985) clustering procedure, as dysfunctional (n = 53), interpersonally distressed (n = 37), and adaptive copers (n = 62). Groups were(More)
This study served to replicate and extend our previously obtained hierarchical model of the relationships among general anxiety vulnerabilities, specific anxiety vulnerabilities and specific anxiety manifestations including panic symptoms, health anxiety, obsessive-compulsive symptoms and worry. Questionnaires assessing these variables, as well as positive(More)
This study evaluated a theoretical hierarchical relationship among the general anxiety vulnerability variable of neuroticism, the specific vulnerability variables of anxiety sensitivity and intolerance of uncertainty, and variables reflecting specific anxiety foci including panic symptoms, health anxiety, obsessive-compulsive symptoms and generalized(More)
The purpose of the present article is to provide unification to a number of somewhat disparate themes in the chronic pain and phobia literature. First, we present a summary review of the early writings and current theoretical perspectives regarding the role of avoidance in the maintenance of chronic pain. Second, we present an integrative review of recent(More)
It has been proposed that high anxiety sensitivity amplifies a number of fears and anxiety reactions. The purpose of this study was to examine whether anxiety sensitivity influences pain-related anxiety and associated cognitive and affective reactions in patients with physically unexplained chronic back pain. Seventy patients with chronic back pain without(More)
This study examined the prevalence of functional gastrointestinal (FGI) disorders, and the association between FGI disorders and measures of affective distress, among a sample of 127 university students. Subjects completed a questionnaire battery including Research Diagnostic Questions for Functional Gastrointestinal Disorders, the Beck Anxiety Inventory,(More)
Most theories of sex ratio adjustment assume that parents will adjust the sex ratio of births (secondary sex ratio) in a manner that maximizes offspring reproductive success (as long as this does not jeopardize parental reproductive success). Survival to maturity is typically the largest component of variance in offspring reproductive success. This should(More)
