RESUMEN
OBJECTIVE: Utilize machine learning models to identify factors associated with seeking medical care for migraine. BACKGROUND: Migraine is a leading cause of disability worldwide, yet many people with migraine do not seek medical care. METHODS: The web-based survey, ObserVational survey of the Epidemiology, tReatment and Care Of MigrainE (US), annually recruited demographically representative samples of the US adult population (2018-2020). Respondents with active migraine were identified via a validated diagnostic questionnaire and/or a self-reported medical diagnosis of migraine, and were then asked if they had consulted a healthcare professional for their headaches in the previous 12 months (i.e., "seeking care"). This included in-person/telephone/or e-visit at Primary Care, Specialty Care, or Emergency/Urgent Care locations. Supervised machine learning (Random Forest) and Least Absolute Shrinkage and Selection Operator (LASSO) algorithms identified 13/54 sociodemographic and clinical factors most associated with seeking medical care for migraine. Random Forest models complex relationships (including interactions) between predictor variables and a response. LASSO is also an efficient feature selection algorithm. Linear models were used to determine the multivariable association of those factors with seeking care. RESULTS: Among 61,826 persons with migraine, the mean age was 41.7 years (±14.8) and 31,529/61,826 (51.0%) sought medical care for migraine in the previous 12 months. Of those seeking care for migraine, 23,106/31,529 (73.3%) were female, 21,320/31,529 (67.6%) were White, and 28,030/31,529 (88.9%) had health insurance. Severe interictal burden (assessed via the Migraine Interictal Burden Scale-4, MIBS-4) occurred in 52.8% (16,657/31,529) of those seeking care and in 23.1% (6991/30,297) of those not seeking care; similar patterns were observed for severe migraine-related disability (assessed via the Migraine Disability Assessment Scale, MIDAS) (36.7% [11,561/31,529] vs. 14.6% [4434/30,297]) and severe ictal cutaneous allodynia (assessed via the Allodynia Symptom Checklist, ASC-12) (21.0% [6614/31,529] vs. 7.4% [2230/30,297]). Severe interictal burden (vs. none, OR 2.64, 95% CI [2.5, 2.8]); severe migraine-related disability (vs. little/none, OR 2.2, 95% CI [2.0, 2.3]); and severe ictal allodynia (vs. none, OR 1.7, 95% CI [1.6, 1.8]) were strongly associated with seeking care for migraine. CONCLUSIONS: Seeking medical care for migraine is associated with higher interictal burden, disability, and allodynia. These findings could support interventions to promote care-seeking among people with migraine, encourage assessment of these factors during consultation, and prioritize these domains in selecting treatments and measuring their benefits.

BACKGROUND AND OBJECTIVES: This population-based analysis characterizes the relative frequency of migraine-related stigma and its cross-sectional relationship to migraine outcomes. We hypothesized that migraine-related stigma would be inversely associated with favorable migraine outcomes across headache day categories. METHODS: OVERCOME (US) is a web-based observational study that annually recruited a demographically representative US sample and then identified people with active migraine using a validated migraine diagnostic questionnaire. It also assessed how frequently respondents experienced migraine-related stigma using a novel 12-item questionnaire (Migraine-Related Stigma, MiRS) that contained 2 factors; feeling that others viewed migraine as being used for Secondary Gain (8 items, α = 0.92) and feeling that others were Minimizing disease Burden (4 items, α = 0.86). We defined 5 groups: (1) MiRS-Both (Secondary Gain and Minimizing Burden often/very often; (2) MiRS-SG (Secondary Gain often/very often); (3) MiRS-MB (Minimizing Burden often/very often); (4) MiRS-Rarely/Sometimes; (5) MiRS-Never. Using MiRS group as the independent variable, we modeled its cross-sectional relationship to disability (Migraine Disability Assessment, MIDAS), interictal burden (Migraine Interictal Burden Scale-4), and migraine-specific quality of life (Migraine Specific Quality of Life v2.1 Role Function-Restrictive) while controlling for sociodemographics, clinical features, and monthly headache day categories. RESULTS: Among this population-based sample with active migraine (n = 59,001), mean age was 41.3 years and respondents predominantly identified as female (74.9%) and as White (70.1%). Among respondents, 41.1% reported experiencing, on average, ≥4 monthly headache days and 31.7% experienced migraine-related stigma often/very often; the proportion experiencing migraine-related stigma often/very often increased from 25.5% among those with <4 monthly headache days to 47.5% among those with ≥15 monthly headache days. The risk for increased disability (MIDAS score) was significant for each MiRS group compared with the MiRS-Never group; the risk more than doubled for the MiRS-Both group (rate ratio 2.68, 95% CI 2.56-2.80). For disability, interictal burden, and migraine-specific quality of life, increased migraine-related stigma was associated with increased disease burden across all monthly headache day categories. DISCUSSION: OVERCOME (US) found that 31.7% of people with migraine experienced migraine-related stigma often/very often and was associated with more disability, greater interictal burden, and reduced quality of life.

OBJECTIVE: In this secondary analysis of mobile health headache diary data, we evaluated the relationship between adherence to medication used for the acute treatment of migraine and lifetime history of an anxiety or depression disorder. BACKGROUND: Medication non-adherence can produce poor clinical efficacy and may be associated with medication overuse. Medication overuse was defined by taking a migraine-specific medication (MSM) for ≥10 days/month, an opioid or barbiturate for ≥10 days/month, or a nonsteroidal anti-inflammatory drug for ≥15 days/month and having ≥15 headache days/month. Extant literature predominantly evaluates fixed-schedule medication adherence. Little is known about predictors of adherence to as-needed medication such as those used for the acute treatment of migraine. METHODS: Adults with prior migraine diagnosis and at least 4 headache days/month completed baseline questionnaires assessing lifetime history of depression or anxiety disorder diagnoses and were asked to record 90 days of once-daily electronic headache diaries soliciting: Headache occurrence; symptoms; medication taken, if any, for the acute treatment of migraine; and their pain level (mild, moderate, severe) when the medication was taken. The 193 participants who completed ≥30 days of headache diary were included in this secondary analysis. RESULTS: A MSM was used as the first medication taken on 45.7% (2825/6176) of headache days. Nearly a quarter of the sample (45/193, 23.3%) overused medications for acute treatment of migraine. Medication overuse was more common in patients with a history of an anxiety disorder, odds ratio (OR) 2.01 (95% confidence interval [CI] 1.01-3.69), but this relationship was not significant when headache days were accounted for, OR 2.02 (95% CI 0.83-4.91). Neither a history of a depression disorder, OR 1.40 (95% CI 0.90-2.16), nor an anxiety disorder, OR 1.11 (95% CI 0.71-1.72), was associated with taking medications early; however, duration of self-monitoring was associated with taking MSM early, OR 1.006 (95% CI 1.004-1.009). CONCLUSION: Lifetime history of depression and anxiety were not associated with taking a MSM early. Medication overuse may be more common in patients who have both migraine and anxiety. Taking a MSM early improved over time for all participants, even when adjusting for a history of an anxiety and or a depression disorder.

Migraine is a highly prevalent neurological disease of varying attack frequency. Headache attacks that are accompanied by a combination of impact on daily activities, photophobia and/or nausea are most commonly migraine. The headache phase of a migraine attack has attracted more research, assessment tools and treatment goals than any other feature, characteristic, or phase of migraine. However, the migraine attack may encompass up to 4 phases: the prodrome, aura, headache phase and postdrome. There is growing recognition that the burden of migraine, including symptoms associated with the headache phase of the attack, may persist between migraine attacks, sometimes referred to as the "interictal phase." These include allodynia, hypersensitivity, photophobia, phonophobia, osmophobia, visual/vestibular disturbances and motion sickness. Subtle interictal clinical manifestations and a patient's trepidation to make plans or commitments due to the unpredictability of migraine attacks may contribute to poorer quality of life. However, there are only a few tools available to assess the interictal burden. Herein, we examine the recent advances in the recognition, description, and assessment of the interictal burden of migraine. We also highlight the value in patients feeling comfortable discussing the symptoms and overall burden of migraine when discussing migraine treatment needs with their provider.
RESUMEN
OBJECTIVE: The ObserVational survey of the Epidemiology, tReatment and Care of MigrainE (OVERCOME; United States) study is a multicohort, longitudinal web survey that assesses symptomatology, consulting, diagnosis, treatment, and impact of migraine in the United States. BACKGROUND: Regularly updating population-based views of migraine in the United States provides a method for assessing the quality of ongoing migraine care and identifying unmet needs. METHODS: The OVERCOME (US) 2018 migraine cohort involved: (I) creating a demographically representative sample of US adults using quota sampling (n = 97,478), (II) identifying people with active migraine in the past year via a validated migraine diagnostic questionnaire and/or self-reported medical diagnosis of migraine (n = 24,272), and (III) assessing consultation, diagnosis, and treatment of migraine (n = 21,143). The current manuscript evaluated whether those with low frequency episodic migraine (LFEM; 0-3 monthly headache days) differed from other categories on outcomes of interest. RESULTS: Among the migraine cohort (n = 21,143), 19,888 (94.1%) met our International Classification of Headache Disorders, 3rd edition-based case definition of migraine and 12,905 (61.0%) self-reported a medical diagnosis of migraine. Respondents' mean (SD) age was 42.2 (15.0) years; 15,697 (74.2%) were women. Having at least moderate disability was common (n = 8965; 42.4%) and around half (n = 10,783; 51.0%) had consulted a medical professional for migraine care in the past year. Only 4792 (22.7%) of respondents were currently using a triptan. Overall, 8539 (40.4%) were eligible for migraine preventive medication and 3555 (16.8%) were currently using migraine preventive medication. Those with LFEM differed from moderate and high frequency episodic migraine and chronic migraine on nearly all measures of consulting, diagnosis, and treatment. CONCLUSION: The OVERCOME (US) 2018 cohort revealed slow but steady progress in diagnosis and preventive treatment of migraine. However, despite significant impact among the population, many with migraine have unmet needs related to consulting for migraine, migraine diagnosis, and getting potentially beneficial migraine treatment. Moreover, it demonstrated the heterogeneity and varying unmet needs within episodic migraine.

BACKGROUND: Although several self-injectable preventive treatments for migraine have become available, they are not yet widely used. Thus, understanding patients' perceptions towards them is limited. OBJECTIVE: This study aimed to inform the design of a preference-elicitation instrument, which is being developed to quantify preventive treatment preferences of people with migraine. METHODS: We conducted a qualitative study involving nine in-person focus groups (three per country) in the United States, the United Kingdom, and Germany. Participants were adults (n = 47) with episodic or chronic migraine who were currently using or had used a prescription preventive treatment for migraine within the previous 5 years. During the focus groups, participants described their experiences of migraine and preventive treatments; handled and simulated self-injection using five different unbranded, fired demonstration auto-injectors and prefilled syringes; and ranked different aspects of preventive treatments by importance. Focus groups were analyzed with a focus on themes that would be feasible or meaningful to include in a subsequent preference-elicitation instrument. RESULTS: Reducing the frequency and severity of migraine attacks was consistently ranked as the most important aspect of preventive treatment. Participants expressed dissatisfaction with available daily oral preventive treatments for migraine they had previously used because they were ineffective or caused intolerable adverse events. Many participants were willing to self-inject a treatment that was effective and tolerable. When presented with devices for self-injecting a preventive treatment for migraine, participants generally preferred autoinjectors over prefilled syringes. Participants especially valued safety features such as the unlocking step and automated needle insertion, and audible and visual dose confirmation increased confidence in autoinjector use. Autoinjector needle protection mechanisms were also appreciated, especially by participants averse to needles, as the needles are not visible. CONCLUSIONS: This study highlights the fact that many people with migraine still lack access to a preventive treatment that is effective and tolerable. In addition to efficacy and safety considerations, treatment decisions may be guided by the mode of administration. In the case of self-injectable preventive treatments, key device characteristics affecting these decisions may be ease of use, comfort, and confidence in self-injection. Insights gained from this study were used to help develop a preliminary set of attributes and levels for a preference-elicitation instrument.

INTRODUCTION: The consistency of the treatment effect of galcanezumab throughout the dosing interval is examined in patients with episodic and chronic migraine. METHODS: This study was a post hoc analysis of clinical trial data from episodic (EVOLVE-1; EVOLVE-2; both 6-month duration) and chronic (REGAIN; 3-month duration) migraine double-blind trials evaluating the efficacy of a once-monthly injection of galcanezumab 120 mg relative to placebo. Adults with episodic (placebo, n = 894; galcanezumab, n = 444) or chronic migraine (placebo, n = 558; galcanezumab, n = 278) were included. Mean change from baseline in weekly migraine headache days, averaged across all months for each week of the dosing interval, was compared between groups and within the galcanezumab group during weeks 1 and 4. Additional analyses examined the mean difference from placebo in weekly migraine headache days and a day-by-day analysis. RESULTS: Weekly migraine headache day reduction was significantly greater with galcanezumab relative to placebo every week (P < 0.001) and did not differ during weeks 1 and 4 for those with episodic (P = 0.740) or chronic migraine (P = 0.231) taking galcanezumab. Estimated probabilities of migraine on day 2 and day 30 did not differ for those with episodic (P = 0.61) or chronic migraine (P = 0.616) taking galcanezumab. CONCLUSION: This analysis demonstrates once monthly galcanezumab exhibits consistent efficacy throughout the dosing interval among the population of patients with migraine in three clinical trials evaluating the efficacy of galcanezumab. There is no evidence from these trials that the effect of galcanezumab "wears off" at the end of the dosing interval. TRIAL REGISTRATION: ClinicalTrials.gov identifier: EVOLVE-1 (NCT02614183); EVOLVE-2 (NCT02614196); REGAIN (NCT02614261).

BACKGROUND: Focus on the frequency of migraine pain may undervalue the total burden of migraine as pain duration and severity may present unique, additive burden. A composite measure of total pain burden (TPB; frequency, severity, and duration) may provide a more comprehensive characterization of pain burden and treatment response in patients with episodic migraine (EM) or chronic migraine (CM). The impact of galcanezumab versus placebo on TPB among patients with EM or CM was analyzed. METHODS: Patients from randomized, double-blind, placebo-controlled episodic (two 6-month studies pooled) and chronic migraine (3-month) studies received once-monthly subcutaneous injection of galcanezumab 120 mg or placebo. A post hoc analysis of TPB for a given month was calculated as severity-weighted duration by multiplying duration (hours) and maximum pain severity (0 = none, 1 = mild, 2 = moderate, 3 = severe) of migraine for each day and summing these over the days in a month. Least square mean change from baseline in monthly TPB across Months 1-6 (EM, N = 444 galcanezumab, N = 894 placebo) and Months 1-3 (CM, N = 278 galcanezumab, N = 558 placebo) were compared using a mixed-model repeated measures model. Correlation of the Migraine Specific Quality of Life Questionnaire (MSQ) and Migraine Disability Assessment Scale (MIDAS) to TPB at baseline was assessed. RESULTS: At baseline, the duration of migraine on a given migraine headache day accounted for the greatest unique proportion of variability (EM, 57.4% and CM, 61.1%) to TPB after adjusting for frequency of migraine headache days and maximum pain severity. The decrease from baseline in monthly TPB was greater with galcanezumab than placebo for patients with EM (68.6 versus 36.2) and CM (102.6 versus 44.4). The average percent reduction of TPB from baseline was significantly greater with galcanezumab compared with placebo in patients with EM (50.8% versus 17.2%) and CM (29.7% versus 11.0%). In patients with EM and CM, TPB correlated with MSQ total score (r = - 0.35 and r = - 0.37) and MIDAS (r = 0.34 and r = 0.32). CONCLUSIONS: Greater reduction in TPB was seen in patients with EM and CM treated with galcanezumab 120 mg once-monthly injection relative to placebo. Discussing TPB supports patient-centric conversations regarding treatment expectations when clinicians are evaluating options for migraine prevention. TRIAL REGISTRATION: ClinicalTrials.gov : # NCT02614183 (I5Q-MC-CGAG; EVOLVE-1), # NCT02614196 (I5Q-MC-CGAH; EVOLVE-2), and # NCT02614261 (I5Q-MC-CGAI; REGAIN) - all 3 trials were registered on 23 November 2015.

OBJECTIVES: To evaluate providers' use and predictors of evidence-based medicine or opioid/barbiturate as first-line acute treatment for children's initial presentation of acute migraine or primary headache. METHODS: This retrospective, observational study utilized patient (children ages 6-17) and provider/encounter characteristics extracted from the patient's Electronic Health Record from 2008-2014 during an initial encounter for migraine or primary headache. The primary outcome was provider evidence-based medicine utilization; overall prescriptions and opioid/barbiturate prescriptions were also evaluated. Hierarchical linear modeling examined whether Level 1 (patient: Demographic, insurance type) and Level 2 (provider/encounter: Treatment setting/location, encounter diagnoses) characteristics influenced outcomes. RESULTS: In all, 38,926 patients (56.7% female, mean age = 12.1) and 1617 providers were evaluated. Only 17.7% of patients were diagnosed with migraine; 16.1% received evidence-based medicine. Older children (OR = 1.07, p < 0.001), females (OR = 1.14, p < 0.001), and those diagnosed with migraine (OR = 4.71, p < 0.001) were more likely to receive evidence-based medicine. Among prescriptions, 15.8% were for opioids/barbiturates. Older children (OR = 1.14, p < 0.001) and those cared for in the emergency department/urgent care (OR = 2.02, p < 0.001) were at increased risk. CONCLUSIONS: Demographics and migraine diagnosis are associated with evidence-based medicine and opioid/barbiturates. Primary care provides an opportunity to target provider interventions to enhance effective pediatric headache treatment.

Objective To examine the influence of acute migraine medication adherence on migraine disability and acute medication satisfaction. Methods Adults with migraine completed three months of daily electronic diaries assessing headache symptoms, acute medication taken, acute medication satisfaction, and daily migraine disability. Repeated measures mixed-effects models examined the effect of initial medication type [migraine-specific medication (MSM) vs. over-the-counter analgesic (OTC) vs. an opiate/barbiturate], the severity of pain at dosing, and their interaction with daily migraine disability and satisfaction with acute medication. Results Participants (N = 337; 92.5% female; 91.1% Caucasian, non-Hispanic; 84.0% with episodic migraine) recorded 29,722 diary days. Participants took acute medication on 96.5% of 8090 migraine days. MSM was most frequently taken first (58%), followed by OTC (29.9%) and an opiate/barbiturate (12.1%). Acute medication was most frequently taken when pain was mild (41.2%), followed by moderate (37.7%) and severe pain (11.4%). Initially dosing with MSM while pain was mild was associated with the lowest daily disability [medication × pain at dosing F (4, 6336.12) = 58.73, p < .001] and highest acute medication satisfaction [medication × pain at dosing F (4, 3867.36) = 24.00, p < .001]. Conclusion Using an MSM (triptan or ergot) first was associated with the lowest migraine disability and highest acute medication satisfaction.

Acute medication adherence is essential to manage chronic, episodic disorders, including headache. This paper describes the development of a measure of acute medication self-efficacy for headache (AMSE-H). Phase 1: 14 AMSE-H items were generated through qualitative interviews with 21 patients and 15 clinical headache experts. Phase 2: Researchers selected 7 AMSE-H items by examining item performance in 35 headache patients. Phase 3: Migraine patients (n = 161) completed the AMSE-H, and measures of outcome expectancies, perceived access to medication, headache management self-efficacy (n = 58) and a 1-week AMSE-H re-test (n = 103). Content validity was established through input of multiple stakeholder groups during item generation. PCA identified two components: cross-episode self-efficacy (eigenvalue = 3.4) and Episode-Specific Self-Efficacy (eigenvalue = 1.0). These subscales are internally consistent (.73-.80), have low 1-week test-retest reliability (rs = .52-.66), and demonstrated solid construct and discriminant validity. The AMSE-H is brief, theory-driven, focused, socially valid measure acceptable to both patients and providers.

Medication adherence is integral to successful treatment of migraine and other headache. The existing literature examining medication adherence in migraine is small, and the methodologies used to assess adherence are limited. However, these studies broadly suggest poor adherence to both acute and preventive migraine medications, with studies using more objective monitoring reporting lower adherence rates. Methods for improving medication adherence are described, including organizational strategies, provider-monitoring and self-monitoring of adherence, regimen strategies, patient education, self-management skills training (e.g., stimulus control, behavioral contracts), and cognitive-behavioral therapy techniques. The article concludes by discussing the future of research regarding adherence to medications for migraine and other headaches.

OBJECTIVES: To assess the influence of triptan or nonsteroidal anti-inflammatory drug (NSAID) use on the likelihood of developing chronic migraine (CM) among persons with episodic migraine (EM). BACKGROUND: CM is common in tertiary headache care, and relative to EM, CM is associated with a number of deleterious outcomes, including higher headache-related disability, reduced health-related quality of life, and increased direct and indirect costs. Symptomatic medication use has emerged as an important risk factor for the development of CM. Limited evidence based on a single year of follow up suggests that the association between NSAID and triptan use with the onset of CM varies in a dose-dependent manner that interacts with headache frequency. However, this interaction has never been explicitly studied. Herein, we evaluate results from a large-scale, 5-year, population-based observational study to characterize these relationships and test the hypothesis that NSAID use may modify the effect of triptan use on CM onset. METHODS: In the American Migraine Prevalence and Prevention (AMPP) study, 11,249 participants had EM in 2005 and provided up to 5 years of annual follow-up data. We analyzed the characteristics of persons with EM 1 year that predicted new onset CM in the subsequent year, focusing on treatment with NSAIDs and triptans as exposures. These adjacent years of data provide the basis for analysis and are termed "couplets." Repeated measures logistic regression with a subject-specific random intercept was used to model the likelihood of transition from EM to CM as a function of NSAID or triptan dose while controlling for a number of covariates including headache features, use of other medications, and the number of couplets per individual. RESULTS: The analysis included 9031 individuals with EM contributing up to 5 years of data and up to 4 couplets each. Results indicated that on average, 55% of the participants used NSAIDs in any given year and 2% transitioned to CM over subsequent years. Among the 20% using triptans, 3% per year transitioned to CM. Among persons with less than 10 headache days per month, frequency of NSAID use was associated with dose-dependent reductions in risk of CM onset. Among those with 10-14 headache days per month, increasing days per month of NSAID use was associated with increasing risk of CM onset. Increasing days per month of triptan use was associated with increased risk of transitioning to CM. Combination use of NSAIDs and triptans was not protective against transition to CM, but was also not statistically significantly associated with increased risk of CM onset. CONCLUSION: Triptan use in EM is associated with an increased risk of CM onset that increases with days of medication use. For NSAIDs, effects depend on headache days per month. NSAIDs are protective in individuals with less than 10 headache days per month but associated with increased risk with 10 or more headache days per month. Combining a triptan and NSAID was not associated with a statistically significant increased risk of CM onset, whereas increased risk of CM onset was significantly associated with triptan monotherapy.

Blood pressure (BP) visit-to-visit variability (VVV) influences the risk of vascular events and mortality. Research has suggested that antihypertensive medication classes may differentially impact VVV. This study evaluated whether antihypertensive medication class differentially impacted BP VVV among hypertensive individuals in a clinical, "real-world" setting as well as the association between VVV and patient characteristics. Clinical observational data were extracted for adults (mean age, 63; 56% female, 86% Caucasian) with hypertension from the Mercy EpicCare EHR-Derived Database (MEDD) (n=183,374) who had at least 4 outpatient visits with BP readings. A multilevel mixed model for change over time estimated between- and within-subject effects on the absolute real VVV of systolic BP. Diuretics significantly lowered VVV (ß=-0.32[-0.39 to-0.25]) and α-/ß-blockers resulted in the highest VVV (ß=0.89 [0.77-1.00]). Being older, female, and having a higher systolic BP and certain comorbid conditions significantly raised VVV (P<.001). The findings from the MEDD were consistent in general with other research on BP VVV. However, the magnitude of effect of antihypertensive medication class and patient characteristics was relatively low (<10% of the BP VVV variance for any one variable). More research is needed to evaluate the extent to which the class of antihypertensive medication class impacts BP VVV in the outpatient setting.

Despite warnings that drinking during pregnancy is unsafe, many women are still at risk for an alcohol-exposed pregnancy (AEP). This article describes the outcomes of a web-based, self-guided change intervention designed to lower the risk for AEPs in a community. A sample of 458 women, between the ages of 18 and 44 years and at risk for an AEP (i.e., any drinking in the past 30 days and not using reliable contraception), participated in the study. A total of 58% of the women enrolled in the self-guided change intervention were no longer at risk for an AEP at the 4-month follow-up. Sublevel analysis revealed that mail and online versions of the intervention were equally successful at reducing risk for an AEP. This study represents a successful implementation of a web-based, self-guided change intervention to reduce risk for an AEP, an intervention with community-wide reach due to the Internet platform.

OPINION STATEMENT: There are a variety of nonpharmacologic treatments for headache. Educating patients about headache and its management, identifying and managing triggers (via diaries), modifying lifestyles, and understanding the importance of adopting and adhering to interventions (either pharmacologic or nonpharmacologic) are relevant to all persons with headache. In addition, specific nonpharmacologic treatments can be used either alone or in conjunction with ongoing pharmacologic intervention. Strong candidates for nonpharmacologic treatment include individuals with significant headache-related disability, comorbid mood or anxiety disorders, difficulty managing stress or other triggers, medication overuse, and patients who prefer a specific treatment. Behavioral treatments (relaxation, biofeedback, and cognitive-behavioral therapy) possess the most evidence for successful headache management. They have a long history of randomized trials showing efficacy and are considered first-line preventive options. Among complementary and alternative treatments, recent positive findings from randomized trials using acupuncture provide evidence of its potential as a first-line intervention. Other complementary and alternative techniques do not have a consistent base of research to recommend them for headache prevention, but they may be used if the patient prefers this approach or when other first-line interventions (nonpharmacologic or pharmacologic) have not provided adequate results. Among "natural" treatments, both butterbur extract and vitamin B2 have shown efficacy in more than one randomized trial and are thus potentially useful first-line preventive interventions.
RESUMEN
The role of the psychologist in chronic headache needs to be tailored to the patient's presentation. For some patients, psychological issues need to be directly addressed (eg, psychiatric comorbidity, difficulties coping with headache, significant problems with sleep and/or stress, medication overuse, and history of abuse). Other situations (eg, patients' beliefs about their readiness to change ability to actively manage headaches, medication adherence, and managing triggers) involve behavioral/psychological principles even when there is no direct contact with a psychologist. This article reviews the literature on the importance of psychological issues in headache management and provides suggestions for how to address behavioral and cognitive factors and their potential for improved headache care.

OBJECTIVE: The objective of this study was to evaluate the effectiveness of the Mercy Migraine Management Program (MMMP), an educational program for physicians and patients. The primary outcome was change in headache days from baseline at 3, 6, and 12 months. Secondary outcomes were changes in migraine-related disability and quality of life, worry about headaches, self-efficacy for managing migraines, emergency room (ER) visits for headache, and satisfaction with headache care. BACKGROUND: Despite progress in the understanding of the pathophysiology of migraine and development of effective therapeutic agents, many practitioners and patients continue to lack the knowledge and skills to effectively manage migraine. Educational efforts have been helpful in improving the quality of care and quality of life for migraine sufferers. However, little work has been performed to evaluate these changes over a longer period of time. Also, there is a paucity of published research evaluating the influence of education about migraine management on cognitive and emotional factors (for example, self-efficacy for managing headaches, worry about headaches). METHODS: In this open-label, prospective study, 284 individuals with migraine (92% female, mean age = 41.6) participated in the MMMP, an educational and skills-based program. Of the 284 who participated in the program, 228 (80%) provided data about their headache frequency, headache-related disability (as measured by the Headache Impact Test-6 (HIT-6), migraine-specific quality of life (MSQ), worry about headaches, self-efficacy for managing headaches, ER visits for headaches, and satisfaction with care at 4 time points over 12 months (baseline, 3 months, 6 months, 12 months). RESULTS: Overall, 46% (106) of subjects reported a 50% or greater reduction in headache frequency. Over 12 months, patients reported fewer headaches and improvement on the HIT-6 and MSQ (all P < .001). The improvement in headache impact and quality of life was greater among those who had more worry about their headaches at baseline. There were also significant improvements in "worry about headaches,""self-efficacy for managing headaches," and "satisfaction with headache care." CONCLUSION: The findings demonstrate that patients participating in the MMMP reported improvements in their headache frequency as well as the cognitive and emotional aspects of headache management. This program was especially helpful among those with high amounts of worry about their headaches at the beginning of the program. The findings from this study are impetus for further research that will more clearly evaluate the effects of education and skill development on headache characteristics and the emotional and cognitive factors that influence headache.

Little is known about how minority groups react to public information that highlights racial disparities in cancer. This double-blind randomized study compared emotional and behavioral reactions to four versions of the same colon cancer (CRC) information presented in mock news articles to a community sample of African-American adults (n = 300). Participants read one of four articles that varied in their framing and interpretation of race-specific CRC mortality data, emphasizing impact (CRC is an important problem for African-Americans), two dimensions of disparity (Blacks are doing worse than Whites and Blacks are improving, but less than Whites), or progress (Blacks are improving over time). Participants exposed to disparity articles reported more negative emotional reactions to the information and were less likely to want to be screened for CRC than those in other groups (both P < 0.001). In contrast, progress articles elicited more positive emotional reactions and participants were more likely to want to be screened. Moreover, negative emotional reaction seemed to mediate the influence of message type on individuals wanting to be screened for CRC. Overall, these results suggest that the way in which disparity research is reported in the medium can influence public attitudes and intentions, with reports about progress yielding a more positive effect on intention. This seems especially important among those with high levels of medical mistrust who are least likely to use the health care system and are thus the primary target of health promotion advertising.

Headache is a chronic disease that occurs with varying frequency and results in varying levels of disability. To date, the majority of research and clinical focus has been on the role of biological factors in headache and headache-related disability. However, reliance on a purely biomedical model of headache does not account for all aspects of headache and associated disability. Using a biopsychosocial framework, the current manuscript expands the view of what factors influence headache by considering the role psychological (i.e., cognitive and affective) factors have in the development, course, and consequences of headache. The manuscript initially reviews evidence showing that neural circuits responsible for cognitive-affective phenomena are highly interconnected with the circuitry responsible for headache pain. The manuscript then reviews the influence cognitions (locus of control and self-efficacy) and negative affect (depression, anxiety, and anger) have on the development of headache attacks, perception of headache pain, adherence to prescribed treatment, headache treatment outcome, and headache-related disability. The manuscript concludes with a discussion of the clinical implications of considering psychological factors when treating headache.
