A Brief Questionnaire to Screen for Quality of Life in Epilepsy The QOLIE-10   总被引:19,自引:8,他引:11  
Summary: Purpose : To evaluate a brief questionnaire to screen aspects of health-related quality of life for persons with epilepsy.
Methods : A study of 304 adults with epilepsy was undertaken at 25 seizure clinics in the United States. It was used for derivation of a brief screening tool from a longer instrument (QOLIE-89).
Results : The 10–item questionnaire (QOLIE-10) covers general and epilepsy-specific domains, grouped into three factors: Epilepsy Effects (memory, physical effects, and mental effects of medication), Mental Health (energy, depression, overall quality of life), and Role Functioning (seizure worry, work, driving, social limits). Scale scores were significantly different among seizure groups (p = 0.003).
Conclusions : The QOLIE-10 can be completed by a patient in several minutes and reviewed rapidly by the physician. This screening tool could provide potentially useful information for initial assessment or follow-up of problem areas that are not commonly evaluated during routine clinical visits with patients with epilepsy.  相似文献

PURPOSE: To develop a Norwegian version of the Quality of Life in Epilepsy Inventory (QOLIE-89) and to confirm its psychometric properties. METHODS: The QOLIE-89 was adapted to Norwegian language through a translation-backtranslation procedure. The assessment included 397 patients with epilepsy. We assessed internal consistency and test-retest reliabilities. Construct validity was assessed by correlating scales with items of the 15D health status questionnaire, and discriminant validity was assessed by comparing scores for known groups. RESULTS: The internal consistency reliability (Cronbach's alpha, 0.76-0.92) and test-retest reliability (intraclass correlation coefficient, 0.67-0.96) for the individual domains were acceptable. Spearman's rank correlations between QOLIE-89 domain scores and corresponding 15D single-item scores were high (p, 0.47-0.76), and generally higher than the associations between noncorresponding items. Most QOLIE-89 items discriminated well between patients according to seizure status, psychiatric comorbidity, and working status; less well after antiepileptic drug use and neurologic comorbidity. CONCLUSIONS: In this cross-sectional survey, the Norwegian version of the QOLIE-89 was reliable and showed properties supporting construct validity, at a level comparable with the original U.S. version.  相似文献

PURPOSE: Previous research suggests that seizure freedom may be necessary to improve health-related quality of life (HRQOL) for epilepsy surgery patients, but little is known regarding the seizure-frequency reduction needed to improve HRQOL among medically treated individuals. METHODS: With data from 134 adults with refractory complex partial seizures participating in a randomized controlled antiepileptic drug (AED) trial, we compared the change in HRQOL across groups having different levels of change in seizure frequency: 100%, 75-99%, 50-74% reduction, and 0-50% increase or decrease. Changes over time within each seizure-reduction group also were assessed. HRQOL was measured by the QOLIE-31, QOLIE-89, and SF-36. RESULTS: Subjects who became seizure free reported significantly more positive change than those who did not on the QOLIE-31 and QOLIE-89 overall scores, the QOLIE-89 mental health, physical health, and epilepsy-targeted composites, as well as the SF-36 mental health summary score. Changes over time in overall QOLIE-31 and QOLIE-89 scores were significantly more positive for subjects who achieved seizure freedom (i.e., 100% reduction in seizure frequency) than for those who did not. No significant change in QOLIE-31 and QOLIE-89 overall scores was observed for subjects who did not achieve seizure freedom. CONCLUSIONS: In this study, HRQOL improvement occurred primarily among patients who achieved complete seizure freedom. Many AED trials use a 50% seizure-frequency reduction criterion as a trial end point, but measurable impacts of this degree of reduction in seizure frequency on HRQOL in this sample were not observed. These results further support striving for seizure freedom as an epilepsy care goal.  相似文献

A psychometric evaluation of a French version of the side-effects and life satisfaction inventory (SEALS) was carried out. SEALS was compared to the quality of life in epilepsy-31 questionnaire (QOLIE-31) and a generic, health-related quality-of-life questionnaire, the Nottingham health profile (NHP). The psychometric properties of SEALS, assessed in 190 adult subjects with epilepsy, included: acceptability, test-retest reliability and validity, multitrait analysis including internal consistency and item-to-scale correlations, construct validity using factor analysis and discriminative validity using associations with disease characteristics and treatment effects, and, correlations with NHP and QOLIE-31 scores for convergent and divergent validity. Both acceptability and reproducibility were good and internal consistency was high (Cronbach's alpha coefficient = 0.92). Factor analysis with varimax rotation identified five factors: the first, related to cognitive function accounted for 26.0% of the variance. Discriminative validity was good for most treatment characteristics (tolerability, seizure control, compliance) and clinical features (epilepsy type, seizure frequency and severity, depressive symptoms). Correlations with the NHP and QOLIE-31 scores were consistently strong. It was concluded that the psychometric properties of the French translation of SEALS were similar to the original English version. In addition, SEALS provides information on quality of life that is complementary to that obtained with QOLIE-31. In particular, with respect to the QOLIE-31, the SEALS provides information on cognitive and neuropsychological aspects of impairment of quality of life, whereas the QOLIE-31 has a broader scope, taking into account multiple aspects of quality of life in epilepsy.  相似文献

PURPOSE: The study goal was to assess the magnitude of change in generic and epilepsy-specific health-related quality-of-life (HRQOL) instruments needed to exclude chance or error at various levels of certainty in patients with medically refractory epilepsy. METHODS: Forty patients with temporal lobe epilepsy and clearly defined criteria of clinical stability received HRQOL measurements twice, 3 months apart, using the Quality of Life in Epilepsy Inventory-89 and -31 (QOLIE-89 and QOLIE-31), Liverpool Impact of Epilepsy, adverse drug events, seizure severity scales, and the Generic Health Utilities Index (HUI-III). Standard error of measurement and test-retest reliability were obtained for all scales and for QOLIE-89 subscales. Using the Reliable Change Index described by Jacobson and Truax, we assessed the magnitude of change required by HRQOL instruments to be 90 and 95% certain that real change has occurred, as opposed to change due to chance or measurement error. RESULTS: Clinical features, point estimates and distribution of HRQOL measures, and test-retest reliability (all > 0.70) were similar to those previously reported. Score changes of +/-13 points in QOLIE-89, +/-15 in QOLIE-31, +/-6.3 in Liverpool seizure severity-ictal, +/-11 in Liverpool adverse drug events, +/-0.25 in HUI-III, and +/-9.5 in impact of epilepsy exclude chance or measurement error with 90% certainty. These correspond, respectively, to 13, 15, 17, 18, 25, and 32% of the potential range of change of each instrument. CONCLUSIONS: Threshold values for real change varied considerably among HRQOL tools but were relatively small for QOLIE-89, QOLIE-31, Liverpool Seizure Severity, and adverse drug events. In some instruments, even relatively large changes cannot rule out chance or measurement error. The relation between the Reliable Change Index and other measures of change and its distinction from measures of minimum clinically important change are discussed.  相似文献

The purpose of this work was to assess the psychometric properties of the German Translation of the Quality of Life in Epilepsy Inventory, QOLIE-31. Internal consistency, construct and criterion validity, and responsiveness were tested in 509 patients with epilepsy who were administered the questionnaires at application or at admittance to the epilepsy center Bethel. Construct validity was tested in patients with different seizure frequencies and different degrees of tolerability of antiepileptic drug (AED) therapy (adverse effects). The scales Epilepsy-Related Fears und Restrictions in Daily Life due to Epilepsy were used as criterion measures. Test-retest reliability (long-term stability) and responsiveness of the questionnaire were analyzed in subgroups of patients who responded to the questionnaires a second time (n = 256). Cronbach's alpha of the QOLIE-31 was 0.94 and varied between 0.76 and 0.90 for the seven subscales. The correlations of the QOLIE with Epilepsy-Related Fears and Restrictions in Daily Life revealed high correlations between Epilepsy-Related Fears and the QOLIE subscale Seizure Worry (r = 0.81, P < 0.01) and the total score (r = 0.62, P < 0.01) and between Restrictions in Daily Life and the QOLIE subscale Social Functioning (r = 0.71) and the total score (r = 0.70, P < 0.01). Seizure frequency had a significant effect especially on the QOLIE subscales Social Functioning, Seizure Worry, and Overall QOL, whereas tolerability of AED therapy affected especially the subscales Medication Effects, Overall QOL, and Energy-Fatigue. The test-retest reliability (intraclass correlation coefficient) was 0.79 for the overall score and varied between 0.59 and 0.78 for the seven subscales. The German Translation of QOLIE-31 is a reliable and valid questionnaire with which to assess QOL in patients with epilepsy and is conceptually similar to the English version. It is a sensitive questionnaire with respect to seizure frequency and tolerability of antiepileptic drug treatment.  相似文献

Summary: Purpose: To assess the psychometric properties of the Quality of Life in Epilepsy Inventory-89 (QOLIE-89) administered via telephone and to compare these properties with data gathered through self-administration.
Methods: A study of 139 patients with epilepsy was undertaken at three clinical sites in the United States. Patients participated in both telephone interview (T) and self-administration (S). Order effect was controlled through randomization (T-S and S-T). Twenty-eight S-T subjects participated in an assessment of the 2-week reproducibility of telephone interviews.
Results: Internal consistency and test-retest reliability levels of the QOLIE-89 overall score were very high across method of administration (T = 0.98; S = 0.98; ICC of T = 0.96). Scores were significantly related to mood (Profile of Mood States, r = -0.76, for both methods, p > 0.001) and two indicators of epilepsy severity (seizure frequency in the past month, T: r = 0.52, p > 0.0001; S: r = 0.54, p > 0.0001; days since last seizure, T: r = 0.28, p > 0.001; S: r = 0.25, p > 0.01), with no significant differences in coefficients by method of administration. Performance of the measure was consistent for patients with unimpaired and impaired memory, using the River-mead Behavioural Memory Test, and across level of education.
Conclusions: Results of this study indicate telephone interview is a viable option for evaluating HRQL in persons with epilepsy and support the reliability and validity of the QOLIE-89 regardless of method of administration.  相似文献

A psychometric evaluation of a French transcultural version of the quality of life in epilepsy inventory-31 (QOLIE-31) was carried out. QOLIE-31 was compared to a generic health-related quality of life questionnaire, the Nottingham health profile (NHP). The psychometric properties of QOLIE-31, assessed in 190 adults with epilepsy, included: acceptability, test-retest reliability and validity (multi-trait analysis including internal consistency and item-to-scale correlations, construct validity using factor analysis, discriminative validity using relationship with disease characteristics, treatment effects, divergent and convergent validity using correlations with NHP scores). Both acceptability and reproducibility were good and internal consistency was high (Cronbach's alpha coefficient = 0.86). Factor analysis with varimax rotation identified seven factors with eigenvalues > 1, with two factors, related to cognitive function and mood, accounting for 46.5% of the variance. However, goodness of fit indices revealed that a model with four factors best fitted the data. The first factor corresponds to a generic mental dimension, the second is equivalent to the cognitive functioning dimension, the third to medication effects including social functioning, and the fourth to seizure worry. Discriminative validity was good for seizure control and treatment tolerability. High correlations between QOLIE-31 and pertinent NHP scales (emotional reactions, energy and social isolation) were observed. The French version of QOLIE-31 thus meets established psychometric criteria for reliability and validity.  相似文献

OBJECTIVE: The aim of the work described here was to develop and validate a Chinese version of the Quality of Life in Epilepsy Inventory-89 (QOLIE-89). METHODS: The original English version of the QOLIE-89 was adapted to the Chinese language through a translation-retranslation procedure. The inventory was then completed by 293 adult patients with epilepsy. Forty patients also completed the Chinese version of the QOLIE-31. Test-retest and internal consistency reliabilities, criterion validity, and discriminative validity were assessed. RESULTS: Test-retest reliability (Pearson's correlation coefficient) for the Chinese version of the QOLIE-89 ranged from 0.70 to 0.98, and internal consistency reliability (Cronbach's alpha) ranged from 0.70 to 0.99. Spearman's rank correlation between the total scores on the Chinese versions of the QOLIE-89 and QOLIE-31 was 0.97, and domain scores ranged from 0.86 to 1.00. QOLIE-89 items could be used to discriminate between patients with respect to epileptic seizure severity and antiepileptic drug side effects. CONCLUSION: The psychometric properties of the Chinese version of the QOLIE-89 are good and similar to those of the American version and can be applied to assess quality of life in adult patients with epilepsy in China.  相似文献

Purpose :  To determine the relative contributions of subjective anxiety, depression, sleep disturbance, and seizure-related variables to quality-of-life scores in adults with epilepsy, and the interrelationships among these factors.
Methods :  Consecutive adult patients with epilepsy attending neurology outpatient clinics were recruited. Patients completed the following scales: Hospital Anxiety and Depression Scale (HADS), Hamilton Anxiety Rating Scale, Medical Outcomes Study (MOS) Sleep Scale, Epworth Sleepiness Scale, and Quality of Life in Epilepsy Inventory-31 (QOLIE-31). Univariate and multivariate linear regression models were used to identify variables associated with QOLIE-31 overall score. Path analysis model was constructed to test for interrelations between the variables.
Results :  Two hundred forty-seven patients completed the questionnaires. By multivariate analysis, in order of degree of contribution, HADS anxiety subscale score, MOS Sleep Scale Sleep Problems Index score, HADS depression subscale score, number of current antiepileptic drugs used, and seizure freedom in the past 4 weeks, significantly correlated with QOLIE-31 overall score, accounting for 65.2% of the variance. Complex interrelationships were present between these factors. A general linear model to predict QOLIE-31 overall score in the presence of these factors was constructed.
Conclusion :  Subjective anxiety, depression, and sleep disturbance exerted greater effect than short-term seizure control on quality of life scores of patients with epilepsy. These factors should be considered simultaneously when evaluating effects of treatment on quality of life.  相似文献
