頭痛による個人へのインパクトを知るにはどうするか

 

論文抄録
Objectives: To examine the reliability and related measurement properties of an illness severity measure for headache derived from responses to a 16-item self-administered questionnaire, the Headache Impact Questionnaire (HImQ), and to determine if there is support for combining measures of pain and disability into a single scaled measure of severity. Methods: A population-based sample of migraine headache sufferers completed the HImQ twice, an average of 38 days apart. The HImQ included questions about number of headaches in the last 3 months, headache duration, last headache, pain intensity (two questions), need for bedrest (two questions), disability in specific domains of activity (seven questions about interference with ability to work, do household chores, and engage in non-work activity), and symptoms (two questions). Results: Test-retest correlations of individual questions ranged from 0.65 to 0.93. In principal components analysis, a single factor with significant loading emerged. One measure of pain intensity (average pain score from 0 to 10) and items related to disability (i.e., missed days due to headache, and reduced effectiveness because of headache) in defined activity domains (work for pay housework, nonwork activities) had the greatest weights on this single factor, supporting prior work on combining measures of pain and disability into a single scale. The HImQ score was derived as the sum of average pain intensity and total lost time in each of the three domains of activity, expressed as lost days. The latter was derived as the sum of actual missed days in each activity domain and reduced effectiveness day equivalents in each activity with a headache. The test-retest correlation was 0.77 for all eligible subjects and 0.85 when one influential outlier was removed. Cronbach's alpha was 0.83. Conclusions: The HImQ score, based on eight items, is a highly reliable and internally consistent measure of headache severity.

  Validity of the Migraine Disability Assessment (MIDAS) score in
  comparison to a diary-based measure in a population sample of
  migraine sufferers. Pain. 2000 Oct;88(1):41-52.

論文抄録

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 of the study was to examine the validity of the MIDAS score, and the five items comprising the score, compared to data from a 90 day daily diary used, in part, to record acute disability from headache. In a population-based sample, 144 clinically diagnosed migraine headache sufferers were enrolled in a 90 day diary study and completed the MIDAS questionnaire at the end of the study. The daily diary was used to record detailed information on headache features as well as activity limitations in work, household chores, and non-work activities (social, family and leisure activities). The MIDAS score was the sum of missed work or school days, missed household chores days, missed non-work activity days, and days at work or school plus days of household chores where productivity was reduced by half or more in the last 3 months. Validity was assessed by comparing MIDAS items and the MIDAS score with equivalent measures derived from the diary. The MIDAS items for missed days of work or school (mean 0.96, median 0) and for missed days of household work (mean 3.64, median 2.0) were similar to the corresponding diary-based estimates of missed work or school (mean 1.23, median 0) and of missed household work (mean 3.93, median 2.01). Values for missed days of non-work activities (MIDAS mean 2.6 and median 1 versus diary mean 2.22 and median 0.95) were also similar. Responses to MIDAS questions about number of days where productivity was reduced by half or more in work (mean 3.77, median 2.00) and in household work (mean 3.92, median 2.00) significantly overestimated the corresponding diary-based measures for work (mean 2.94, median 1.06) and household work (mean 2.22, median 0.98). Nonetheless, the overall MIDAS score (mean 14.53, median 9.0) was not significantly different form the reference diary-based measure (mean 13.5, median 8.4). The correlation between the MIDAS summary score and an equivalent diary score was 0.63. The group estimate of the MIDAS score was found to be a valid estimate of a rigorous diary-based measure of disability. The mean and median values for the MIDAS score in a population-based sample of migraine cases were similar to equivalent diary measures. The correlation between the two measures was in the low moderate range, but expected given that two very different methods of data collection were compared.

  computerized health survey: the headache impact test (HIT). Qual Life
  Res. 2003 Dec;12(8):953-61

論文抄録

BACKGROUND: Headache impact test (HIT) is a precise, practical tool that quantifies the impact of headache on respondents' lives. It is the first widely-available dynamic health assessment (DynHA). Applications of this brief, precise survey include population based screening for disabling headaches, tracking of individual patient scores over time, disease management programs and others. We use data from Internet HIT assessments during the fall of 2000 to (1) evaluate characteristics of respondents and assessments, (2) assess the utility of joint administration of HIT and the SF-8 Health Survey (SF-8) to screen for migraine and depression, and (3) explore associations between HIT scores and subsequent healthcare-related attitudes and behaviors. METHODS: We analyzed Internet HIT surveys completed between 9/1 and 11/30/2000 (n = 19,195). Subsamples include respondents who also completed (1) a 12-item Internet survey assessing severity, frequency, cause and management of headaches; (2) an e-mail survey measuring healthcare-related behaviors; (3) the SF-8; or (4) the website registration process, providing age and gender data. We used analysis of variance (ANOVA) to evaluate HIT score differences associated with age, gender, headache severity or frequency, and healthcare-related behaviors and attitudes and chi2 tests to assess the prevalence and comorbidity of migraine and depression. RESULTS: Three-quarters of respondents achieved a precise HIT score in < or = 5 items. Most had moderate/severe headaches; 65% had headaches at least monthly. HIT scores were directly related to headache severity and frequency. Most respondents were females, with significantly higher HIT scores than males. Most HIT respondents were between ages 25 and 54 (HIT scores were higher for younger respondents). Sixty four percent screened positive for migraine; 20% for depression. Both conditions were more prevalent among females than males. Comorbid migraine and depression was 50% more prevalent among females and increased with age until age 50. Patients with worse headache impact were more likely to seek care, discuss headaches with their providers and find HIT useful. CONCLUSIONS: It is feasible to use Internet-based dynamic assessments to measure health status. These data complement previous results showing that HIT differentiates respondents according to headache characteristics (severity and frequency). HIT plus SF-8 yields a practical screen for migraine and depression in headache patients and may lead to more effective treatment for patients with these conditions. Preliminary findings suggest that the experience of taking HIT on the Internet may motivate headache patients to seek care and discuss headaches with their providers.

論文抄録

Migraine symptoms and therapy side effects cause significant functional disability that can result in work and productivity losses. Effective, well-tolerated migraine therapy with rapid onset of relief could decrease work and productivity losses. The Migraine Work and Productivity Loss Questionnaire (MWPLQ) evaluates the impact of migraine and migraine therapy on paid work. Data from a randomized, open-label extension study were collected over 3 months. Migraineurs were randomized to either rizatriptan (5HT1B/1D receptor agonist) or their usual migraine therapy. Data were analyzed from 164 patients who experienced at least one work-related migraine. Internal consistency (Cronbach's alpha) for the work difficulty domains ranged from 0.80 to 0.95. Work loss and work difficulty were moderately correlated (r = 0.39-0.58) with migraine severity and functional ability. Differences were found favoring rizatriptan for absenteeism (1.3 vs 2.4 h), effectiveness at work (62% vs 49%), and difficulty with work-related tasks (p < 0.01). The MWPLQ demonstrated favorable measurement characteristics in this study and could be an important research tool for future evaluations of migraine-related work disability.

論文抄録

OBJECTIVE: To develop and validate a brief survey of migraine-related quality-of-life issues. The Headache Needs Assessment (HANA) questionnaire was designed to assess two dimensions of the chronic impact of migraine (frequency and bothersomeness). METHODS: Seven issues related to living with migraine were posed as ratings of frequency and bothersomeness. Validation studies were performed in a Web-based survey, a clinical trial responsiveness population, and a retest reliability population. Headache characteristics (eg, frequency, severity, and treatment), demographic information, and the Headache Disability Inventory were used for external validation. RESULTS: The HANA was completed in full by 994 adults in the Web survey, with a mean total score of 77.98 +/- 40.49 (range, 7 to 175). There were no floor or ceiling effects. The HANA met the standards for validity with internal consistency reliability (Cronbach alpha =.92, eigenvalue for the single factor = 4.8, and test-retest reliability = 0.77). External validity showed a high correlation between HANA and Headache Disability Inventory total scores (0.73, P<.0001), and high correlations with disease and treatment characteristics. CONCLUSIONS: These data demonstrate the psychometric properties of the HANA. The brief questionnaire may be a useful screening tool to evaluate the impact of migraine on individuals. The two-dimensional approach to patient-reported quality of life allows individuals to weight the impact of both frequency and bothersomeness of chronic migraines on multiple aspects of daily life.

論文抄録

OBJECTIVE: This study was designed to assess the test-retest reliability, internal consistency, and validity of a Japanese translation of the Migraine Disability Assessment (MIDAS) Questionnaire in a sample of Japanese patients with headache. BACKGROUND: Previous studies have demonstrated that the English-language version of the MIDAS Questionnaire is a reliable and valid instrument for the assessment of migraine-related disability. Any translations of the MIDAS Questionnaire must also be assessed for reliability and validity. METHODS: Study participants were recruited from the patient population attending either the Neurology Department of Kitasato University or an affiliated clinic. Participants were eligible for study entry if they had 6 or more primary headaches per year. For reliability testing, participants completed the MIDAS Questionnaire on 2 occasions, exactly 2 weeks apart. To assess validity, patients were also invited to participate in a 90-day daily diary study. Composite measures from the 90-day diaries were compared to equivalent MIDAS measures (ie, 5 questions on headache-related disability and 1 question each on average pain intensity and headache frequency in the last 3 months) and to the total MIDAS score obtained from a third MIDAS Questionnaire completed at the end of this 90-day period. RESULTS: One hundred one patients between the ages of 21 and 77 years were recruited (81 women and 20 men). Ninety-nine patients (80 women and 19 men) participated in the diary study. At baseline, 46.5% of patients were MIDAS grade I or II (minimal, mild, or infrequent disability), 22.2% were MIDAS grade III (moderate disability), and 31.3% were MIDAS grade IV (severe disability). Test-retest Spearman correlations for the 5 disability questions and the questions on average pain intensity and headache frequency ranged from 0.59 to 0.80 (P<.0001). The test-retest Spearman correlation coefficient for the total MIDAS score was 0.83 (P<.0001). The degree to which individual MIDAS questions correlated with the diary-based measures ranged from 0.36 to 0.88. The correlation between the total MIDAS score and the equivalent diary-based measure was 0.66. In general, the mean and median values for the MIDAS items and total MIDAS score were similar to the means and medians for the diary-based measures. However, the mean MIDAS scores for the number of days on which headache was experienced and the number of missed workdays were significantly different compared to the diary-based estimates for these items (P<.05). In addition, the mean MIDAS score for the number of days of missed housework was significantly higher than the corresponding diary-based estimate (P<.01). CONCLUSIONS: The results from this study show that the Japanese translation of the MIDAS Questionnaire is comparable with the English-language version in terms of reliability and validity.
