The cognitive-behavioral, fear-avoidance (FA) model of chronic pain (Vlaeyen JWS, Kole-Snijders AMJ, Boeren RGB, van Eek H. Fear of movement/(re)injury in chronic low back pain and its relation to behavioral performance. Pain 1995a;62:363-72) has found broad empirical support, but its multivariate, predictive relationships have not been uniformly validated.(More)
BACKGROUND Hearing loss is common among older adults and has consequences for sufferers, families and society, but there is substantial unmet need for intervention. Screening could expedite intervention and improve outcomes. METHODS We use Markov models to estimate the incremental cost-effectiveness ratio (ICER) of potential screening programmes compared(More)
A cross-sectional survey for seropositivity to cysticercosis of pigs in the Yucatan Peninsula, Mexico, was carried out in 1996 together with a standardized questionnaire on predetermined individual pig and household risk factors for porcine infection. Serum samples from 697 pigs were analysed by immunoblot for antibodies to Taenia solium cysticercosis and(More)
UNLABELLED The differential diagnosis of headache is often challenging, with significant clinical and socioeconomic consequences of incomplete or inaccurate diagnosis. Overlapping symptoms contribute to the diagnostic challenge. Four female patients, ages 26 to 69 with standing diagnoses of migraine, were evaluated and treated for complaints of chronic,(More)
Electronic questionnaires for pain assessment are becoming increasingly popular. There have been no published reports to establish the equivalence or psychometric properties of common pain questionnaires administered via desktop computers. This study compared responses to paper (P) and touch screen electronic (E) versions of the Short-Form McGill Pain(More)
OBJECTIVES An extensive body of research suggests that maladaptive beliefs about chronic pain can have a negative impact on patient adherence and treatment response. A series of studies to develop and validate a clinically-based, self-report instrument for pain beliefs, the Cognitive Risk Profile for Pain (CRPP), was undertaken. We sought to expand the(More)
OBJECTIVE To further develop an empirically based classification system for chronic pain patients through the examination of age and sex differences, and incorporation of pain duration in the grouping algorithm. SUBJECTS Three hundred seventy-four chronic pain patients (300 aged 13 to 59 years; 74 aged 60 to 89 years) assessed at an outpatient,(More)
A Western blot assay for identification of 26 kDa and/or 8 kDa antigens in a crude saline extract (CSE) of Taenia solium metacestodes, previously developed for human cysticercosis, was evaluated for use with pigs. The test population used for assay standardisation consisted of 45 cysticercotic pigs (5 pigs positive by necropsy and 40 selected by tongue(More)
The Pressure-State-Response framework for environmental reporting was used as a basis to develop a long-term study of people's perceptions of the state of the New Zealand environment. A postal survey of 2000 people, randomly drawn from the New Zealand electoral roll was used to gather data--an effective response rate of 48% was achieved. A range of(More)
War veterans are at increased risk for chronic pain and co-occurring neurobehavioral problems, including posttraumatic stress disorder (PTSD), depression, alcohol-related problems, and mild traumatic brain injury (mTBI). Each condition is associated with disability, particularly when co-occurring. Pain acceptance is a strong predictor of lower levels of(More)
