A cross-sectional survey to assess the migraineur's medication decision-making beliefs: determining when a migraine is triptan-worthy.

Objectives: To investigate the factors that influence a migraineur's beliefs regarding oral triptans for the acute treatment of migraines and to provide further insight into patients' decision-making process when faced with migraine.

Methods: A multicenter, cross-sectional, observational study of subjects currently prescribed an oral triptan medication for the acute treatment of migraine headaches. Subjects were recruited from 6 headache clinics and one primary care practice in the United States.

A cross-validation of the provisional diagnostic instrument (PDI-4).

Background: The Provisional Diagnostic Instrument (PDI-4) is a brief, adult self-report instrument for 4 common psychiatric diagnoses in primary care patients: major depressive episode (MDE), generalized anxiety disorder (GAD), attention deficit hyperactivity disorder (ADHD), and bipolar I disorder based on past or present mania. Our objective was to assess validity of the PDI-4 in a population independent of the study population originally used to develop the scale.

Methods: An online version of the 17-item PDI-4 was administered to 1,047 adults in the US; respondents also completed the PHQ-9, HADS-A, CAARS-S, and MDQ within the online survey.
