AbstractExcessive medication intake is a risk factor for the development of medication-overuse headache (MOH), a condition characterized by an increase of headache frequency to a daily or near-daily pattern. As yet, it is largely unknown why some patients overuse medication. In this study, we examined to what extent attitudes about pain medication, especially perceived need and concerns, and problem-solving are related to MOH. Patients with migraine (n=133) and MOH with a history of migraine (n=42) were recruited from a tertiary headache referral center and completed questionnaires measuring problem-solving and attitudes about pain medication. A problem-solving mode aimed at solving pain was associated with a higher need for and concerns about medication intake. Interestingly, in a model accounting for demographic factors and pain intensity, attempts to control pain, need for medication, and concerns about scrutiny by others because of medication intake all had a unique value in accounting for MOH. Results are discussed in terms of how repeated attempts to solve pain may trigger overuse of medication, even in the presence of clear negative consequences. Repeated attempts at solving pain may increase the need for analgesic medication, despite obvious costs. This mechanism might contribute to the problem of medication-overuse headache.Copyright © 2011 International Association for the Study of Pain. Published by Elsevier B.V. All rights reserved.
