BACKGROUND The Migraine Disability Assessment (MIDAS) instrument is a five-item questionnaire developed to measure headache-related disability and improve doctor-patient communication about the functional consequences of migraine. OBJECTIVES To examine the test-retest reliability and internal consistency of the five items and of the overall MIDAS score in(More)
BACKGROUND Migraine is a highly prevalent and disabling illness that remains substantially undiagnosed in primary care. Because of the potential value of a screening tool, the current study was designed to establish the validity and reliability of a brief, self-administered migraine screener in patients with headache complaints in the primary care setting.(More)
OBJECTIVE This study reports on the influence of migraine and comorbid depression on health-related quality of life (HRQoL) in a population-based sample of subjects with migraine and nonmigraine controls. METHODS Two population-based studies of similar design were conducted in the United States and United Kingdom. A clinically validated, computer-assisted(More)
The Migraine Disability Assessment (MIDAS) questionnaire is a brief, self-administered questionnaire designed to quantify headache-related disability over a 3 month period. The MIDAS score has been shown to have moderately high test-retest reliability in headache sufferers and is correlated with clinical judgment regarding the need for medical care. The aim(More)
Difficulties in predicting "real life" physiological variation from responses to controlled stress tasks suggest the need for more ecologically valid laboratory challenges. The Social Competence Interview (SCI) measures physiological changes elicited by re-experiencing a life situation in which a valued striving was unexpectedly hindered. The 14-minute(More)
BACKGROUND It is well established that migraine aggregates within families. Less is known about the influence of proband characteristics (e.g., age at onset, headache severity) on familial aggregation. OBJECTIVE To examine the association between the proband's migraine severity and age at migraine onset and familial aggregation of migraine. METHODS The(More)
BACKGROUND A large number of headache sufferers with features of migraine fail to meet criteria for strict migraine (SM; migraine with or without aura) but do meet criteria for probable migraine (PM). OBJECTIVES To estimate the prevalence of PM, to compare the epidemiologic profiles of SM and PM, and to assess the disability and impact on the(More)
AIMS We used data from the General Longitudinal Overactive Bladder Evaluation (GLOBE) to understand predictors of variation in urgency and urinary incontinence (UI) symptoms over time. METHODS A random sample of Geisinger Clinic primary care patients (men and women) 40+ years of age were recruited for a survey of bladder control symptoms at baseline and(More)
OBJECTIVE To determine the prevalence and distribution of migraine in the United States as well as current patterns of health care use. METHODS A random-digit-dial, computer-assisted telephone interview (CATI) survey was conducted in Philadelphia County, PA, in 1998. The CATI identifies individuals with migraine (categories 1.1 and 1.2) as defined by the(More)
BACKGROUND Contingency management interventions that provide tangible incentives based on objective indicators of drug abstinence have improved treatment outcomes of substance abusers, but have not been widely implemented in community drug abuse treatment settings. OBJECTIVE To compare outcomes achieved when a lower-cost prize-based contingency management(More)
