Reliability, validity, and clinical utility of the Migraine-ACT questionnaire

BACKGROUND: The 4-item Migraine-ACT questionnaire is an assessment tool for use by primary care physicians to identify patients who require a change in their current acute migraine treatment. It has been shown to be easy to use, and to be reliable and accurate in its assessments. OBJECTIVES: To further analyze the Migraine-ACT study database, providing additional information on the reliability, validity, and potential clinical utility of the questionnaire. METHODS: Reliability was assessed by recording the distribution of Migraine-ACT scores recorded at baseline and 1 week later (test-retest reliability). Analyses of consistency of Migraine-ACT scores were conducted on the total sample of patients and for the separate centers, using Pearson and Spearman correlations. Validity was assessed by comparing the t-discrimination values for clinically relevant questions within domains of the original 27-item questionnaire. Reliability and validity were also assessed by constructing an "alternative" (Form B) Migraine-ACT questionnaire, derived from an analysis of the second-best items in each domain in the original study data. Clinical utility was assessed using Pearson pairwise correlations to compare Migraine-ACT scores with clinically defined criteria as analyzed by the SF-36 Quality of Life questionnaire, the Migraine Disability Assessment (MIDAS) questionnaire, and the Migraine Therapy Assessment (MTAQ) questionnaire. RESULTS: The distribution of Migraine-ACT scores between the 2 completions of the questionnaire was consistent for the total sample (test-retest reliability, r= .81) and between the individual countries (r= .61 to .92). In this study, the validity (assessed as t-discrimination) of the Migraine-ACT "impact" and "global assessment of relief" questions were markedly higher than those of other endpoints used in migraine clinical studies. The Form B Migraine-ACT questionnaire was almost as reliable and accurate as the original Form A questionnaire. The distribution of Migraine-ACT scores was: 0 = 12.6%, 1 = 13.7%, 2 = 14.7%, 3 = 20.5%, and 4 = 38.4%. The change in Migraine-ACT score correlated with, and had a linear relationship with changes in SF-36, MIDAS, and MTAQ scores, and indicated that a Migraine-ACT score of 相似文献

Reliability and validity of the Finnish version of the prosthesis evaluation questionnaire

Background: Thus far there have been no specific patient-reported outcome instrument in Finnish for health-related quality of life (HRQoL) assessment after major lower extremity amputation and successful prosthesis fitting.

Methods: The prosthesis evaluation questionnaire (PEQ) was translated and cross-culturally adapted into Finnish. Participants completed a questionnaire package including the Finnish version of the PEQ and the 15?D HRQoL instrument. Scales (n?=?10) were tested for internal consistency, floor-ceiling effect, and reproducibility for which participants completed the PEQ twice within a 2-week interval. Validity was tested by estimating the correlation between the 15?D index and the scales. The authors included 122 participants who had completed the questionnaire on two separate occasions in the final analysis.

Results: Mean scale scores of the 10 scales varied from 52 to 83. Cronbach’s alphas ranged from 0.67 to 0.96. The total score showed no floor-ceiling effect. Reproducibility of the scales was good (intraclass correlation coefficient, 0.78–0.87; coefficient of repeatability, 19–36). Significant correlations were observed between the 15?D index and the scales for ambulation, social burden, usefulness, and well-being.

Conclusions: This study provided evidence of the reliability and validity of the Finnish version of the PEQ in assessing the HRQoL among major lower extremity amputated patients who have been fitted with prosthesis.

• Implications for rehabilitation

• Measurement of quality of life during rehabilitation can provide important information on patients’ well-being.

• The prosthesis evaluation questionnaire (PEQ) is a valid instrument for assessing health-related quality of life (HRQoL) after major lower extremity amputation.

• This study provided evidence of the reliability and validity of the Finnish version of the PEQ for assessing HRQoL among patient who have undergone major lower extremity amputation.

     

Head-HUNT: validity and reliability of a headache questionnaire in a large population-based study in Norway

We have assessed the validity and reliability of a self-administered headache questionnaire used in the 'Nord-Tr?ndelag Health Survey 1995-97 (HUNT)' in Norway, by blindly comparing questionnaire-based headache diagnoses with those made in a clinical interview of a sample of the participants. Restrictive questionnaire-based diagnostic criteria for migraine, assessed according to modified criteria of the International Headache Society, performed excellently in selecting 'definite' migraine patients (100% positive predictive value). The best agreement concerning migraine diagnoses was achieved by using a liberal set of criteria (kappa 0.59). Similar agreement was found evaluating patient status as headache sufferers, and as sufferers from frequent headaches (>6 days per month) (kappa 0.57 and 0.50, respectively). The kappa values of non-migrainous headache and chronic headache (> 14 days per month) were 0.43 and 0.44, respectively. The results suggest that our self-administered questionnaire may be suitable in identifying a population with 'definite' migraine, and the questionnaire is an acceptable instrument in determining the prevalence in Nord-Tr?ndelag of headache sufferers, migraine, non-migrainous headache, and frequent or chronic headache sufferers.

Reliability and validity of the Japanese Migraine Disability Assessment (MIDAS) Questionnaire

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.

Validation of a german language questionnaire for screening for migraine, tension-type headache, and trigeminal autonomic cephalgias

BACKGROUND: To develop a German language questionnaire for screening for migraine, tension-type headache, and trigeminal autonomic cephalgias. OBJECTIVE: Aim of the study was to develop a German language self-administered headache questionnaire for screening for migraine (MIG), tension-type headache (TTH), and trigeminal-autonomic cephalgias (TAC). METHODS: Questionnaire-based diagnoses were blindly compared with those of headache experts. RESULTS: Overall 278 headache patients (MIG = 97, TTH = 60, TAC = 98, MIG plus TTH = 23) as well as 42 patients with low back pain without headache and 47 healthy subjects were studied. The Cohen's kappa for 7 headache syndromes including all combination diagnoses was 0.64 (95% CI 0.58-0.70). Sensitivity and specificity for migraine were 0.73 and 0.96, for TTH 0.85 and 0.98, for TAC 0.63 and 0.99, and for MIG plus TTH 0.62 and 0.97, respectively. Ignoring all combination diagnoses, the kappa-coefficient for the monodiagnoses MIG, TTH, and TAC (193 out of 278 patients) was 0.93 (CI 0.83-1.0). The retest-reliability (4 weeks later) was 0.95. CONCLUSION: We present the first questionnaire in German language including 3 most common primary headaches for use in epidemiological research.     

Assessment of migraine disability using the migraine disability assessment (MIDAS) questionnaire: a comparison of chronic migraine with episodic migraine

BACKGROUND: Chronic migraine is the most common type of chronic daily headache seen in headache tertiary care centers. Most patients with chronic migraine report their ability to function and feeling of well-being as severely impaired. OBJECTIVE: To measure the headache-related disability of patients with chronic migraine using the Migraine Disability Assessment (MIDAS) Questionnaire, comparing it with that obtained in a control group of patients with episodic migraine. METHODS: The clinical records of 703 patients with chronic daily headache treated in a headache specialty clinic were reviewed to identify 182 with chronic migraine who were evaluated using the MIDAS at their initial visit. Our control group consisted of 86 patients with episodic migraine. RESULTS: Of the 182 patients with chronic migraine, 127 (69.8%) were overusing acute-care medication. Patients were predominantly women (72.5%), with a mean age of 38.3 years. The group with episodic migraine consisted of 59 women (68.6%), with a mean age of 36.1 years. No statistically significant demographic differences were observed between the two groups. The group with chronic migraine had more total headache days over 3 months (66.7 versus 15.5, P<.001), missed more days of work or school (5.3 versus 2.3, P =.0007), had more reduced effectiveness days at work or school (11.9 versus 4.6, P =.0001), missed more days of housework (16.5 versus 3.3, P<.0001), and missed more days of family, social, or leisure activities (7.0 versus 5.5, P =.03). The group with chronic migraine was more likely to be in MIDAS grade IV (64.3% versus 43.2%, P =.001), reflecting the great likelihood of severe disability in this group. The average total MIDAS score was 34.9 in the group with chronic migraine versus 19.3 in the group with episodic migraine (P<.001). CONCLUSION: In subspecialty centers, patients with chronic migraine demonstrate remarkable impairment of their daily activities and are severely burdened by their headache syndrome, reflected by their high MIDAS scores. The chronicity and pervasiveness of migraine thus is associated with increased functional impairment as well as increase in headache frequency.

Reliability and validity of the Norwegian WHOQOL-OLD module

The aim of this study was to examine the validity and reliability of the Norwegian WHOQOL-OLD six-facet, 24-item module designed for assessing generic quality of life cross-culturally among the elderly. Using quota-stratified sampling defined on the basis of sex, age and geographical representation, 401 respondents were drawn from Statistics Norway and completed postal surveys. An additional 89 elderly completed personal interviews. Correlation and multivariate analyses partly confirmed the relevance of individual items and facets in both groups. All items correlated significantly higher with their original facets, although almost half of these items correlated with other facets in both groups. Multiple regression analysis of the module and two overall questions (dependent variables) showed that three facets made significant contributions to overall health, with Social Participation (B = 0.09) contributing most strongly in the postal-group. In the interview-group, only Social Participation (B = 0.20) was found to make a significant contribution, and this was in relation to overall health satisfaction. When the WHOQOL-BREF total score was considered as the dependent variable, different facets contributed significantly in both groups. Exploratory factor analysis of the WHOQOL-OLD in the combined group of both postal and interview samples, resulted in a five-factor solution (eigenvalues >1) explaining 65% of the cumulative variance in five of the six originally operationalized facets. The most conceptually clear facets were Death and Dying and Sensory Abilities. Further, confirmatory factor analyses in the combined group demonstrated a model with good fit, but with high covariance between the factors. Acceptable internal consistency was shown except for the Past, Present and Future Activities in both groups. Since construct validity was only partially confirmed, exploration of the scale's conceptual validity needs further testing in Norwegian and international samples.

Reliability and validity in a nutshell

Aims. To explore and explain the different concepts of reliability and validity as they are related to measurement instruments in social science and health care. Background. There are different concepts contained in the terms reliability and validity and these are often explained poorly and there is often confusion between them. Design. To develop some clarity about reliability and validity a conceptual framework was built based on the existing literature. Results. The concepts of reliability, validity and utility are explored and explained. Conclusions. Reliability contains the concepts of internal consistency and stability and equivalence. Validity contains the concepts of content, face, criterion, concurrent, predictive, construct, convergent (and divergent), factorial and discriminant. In addition, for clinical practice and research, it is essential to establish the utility of a measurement instrument. Relevance to clinical practice. To use measurement instruments appropriately in clinical practice, the extent to which they are reliable, valid and usable must be established.
