Summary: Seizure severity scales have recently been identified as an important additional outcome measure in trials of new antiepileptic drugs (AEDs). The National Hospital Seizure Severity Scale (NHS3) is presented as a refined version of the Chalfont Seizure Severity Scale. The principal advantages of the new version are that it is quicker and simpler to apply, the limits of reliability are now clearly defined, and construct validity for the scale is available. The scale is administered by a health professional during an interview with a patient and a witness to the seizures. It contains seven seizure-related factors and generates a score from 1 to 27. An intraclass correlation coefficient of 0.90 was obtained during interobserver and test-retest reliability assessment, suggesting that the scale is sufficiently reliable for group studies. Scores for an individual patient should be interpreted with caution in light of the limits of agreement obtained. Validation experiments indicate that NHS3 measures seizure severity in a manner compatible with the subjective impression of people with epilepsy. We suggest that the NHS3 is a valid, easily applicable measure of seizure severity that is acceptably reliable for use in trials of novel AEDs.  相似文献

The factor structure of the Dutch translation of the Autism-Spectrum Quotient (AQ; a continuous, quantitative measure of autistic traits) was evaluated with confirmatory factor analyses in a large general population and student sample. The criterion validity of the AQ was examined in three matched patient groups (autism spectrum conditions (ASC), social anxiety disorder, and obsessive-compulsive disorder). A two factor model, consisting of a "Social interaction" factor and "Attention to detail" factor could be identified. The internal consistency and test-retest reliability of the AQ were satisfactory. High total AQ and factor scores were specific to ASC patients. Men scored higher than women and science students higher than non-science students. The Dutch translation of the AQ is a reliable instrument to assess autism spectrum conditions.  相似文献

In this study, the authors aimed to investigate the reliability and validity of the Somatosensory Amplification Scale (SSAS) that was developed by Barsky et al. in the Turkish population. The study was carried out with 42 patients with Fibromyalgia Syndrome and Asthma Diseases attending to outpatient Physical Therapy and Rehabilitation and Chest Diseases clinics and 86 healthy students from Karadeniz Technical University. SSAS scores were normally distributed, and had acceptable test-retest reliability (r: 0.73) and internal consistency (alpha, 0.62-0.76). Item to scale correlations varied from 0.10 to 0.72, and most were highly significant. Whereas, one item (item 1) in the control group and one item (item 2) in the patients group had low item-total score correlation (r < 0.15). Criterion related validity of the SSAS was shown with significant correlation between the Symptom Interpretation Questionnaire, the Toronto Alexithymia Scale and the Symptom Check List 90 Revised somatization subscale. The validity analysis of the scale resulted in a very high significant difference (P < 0.01) between the mean SSAS scores of the control and patient's group. Test-retest, internal reliability, and item-total score correlation, discriminating power for specific groups and criterion related validity of the SSAS show that the scale has acceptable reliability and validity for the Turkish population.  相似文献

限定刑事责任能力的应用   总被引:2,自引:0,他引:2  
目的:探讨限定刑事责任能力评定量表(DCRRS)在广州地区责任能力3级评定中的应用。方法:采用DCRRS回顾性评定刑事责任能力鉴定504例,进一步检验该量表的信效度及其和专家鉴定结论的一致性。结果:DCRRS的分半信度为0.90,各条目之间及其与总量表分之间的相关均有统计学意义(r=0.11-0.91,P〈0.05)。据DCRRS的参考划界分分组,无、限定和完全责任能力3组间及两两间总量表分的差异均具有统计学意义(P〈0.001)。DCRRS评定和专家鉴定两种责任能力分级方法的结果一致性较好(Kappa值=0.71,P〈0.001),建立判别函数,回代的判别正确率分别为96.2%和86.7%。结论:DCRRS在广州地区使用的信效度良好,可推广用于责任能力3级评定的辅助参考。  相似文献

Fatigue after stroke: the development and evaluation of a case definition   总被引:2,自引:0,他引:2  
OBJECTIVE: While fatigue after stroke is a common problem, it has no generally accepted definition. Our aim was to develop a case definition for post-stroke fatigue and to test its psychometric properties. METHODS: A case definition with face validity and an associated structured interview was constructed. After initial piloting, the feasibility, reliability (test-retest and inter-rater) and concurrent validity (in relation to four fatigue severity scales) were determined in 55 patients with stroke. RESULTS: All participating patients provided satisfactory answers to all the case definition probe questions demonstrating its feasibility For test-retest reliability, kappa was 0.78 (95% CI, 0.57-0.94, P<.01) and for inter-rater reliability kappa was 0.80 (95% CI, 0.62-0.99, P<.01). Patients fulfilling the case definition also had substantially higher fatigue scores on four fatigue severity scales (P<.001) indicating concurrent validity. CONCLUSION: The proposed case definition is feasible to administer and reliable in practice, and there is evidence of concurrent validity. It requires further evaluation in different settings.  相似文献

Abstract  Despite a rapid increase in disabled elderly in Japan, the burden of the caregiver has not been properly assessed due to a lack of objective measurements. Our study was aimed at adapting and validating the Zarit Caregiver Burden Interview (ZBI) in Japan, which is one of the most widely used measurements for caregivers' burden in the United States. Sixty-six caregivers answered the self-administered questionnaire, involving the Japanese version of the ZBI and questions regarding their caregiving situation. Our study demonstrated that the Japanese version of the ZBI had equally as high reliability and validity as the original version. The Japanese ZBI had a high test—retest reliability (r = 0.76) and internal consistency (Cronbach's alpha = 0.93). The total score of the ZBI was highly correlated with the caregivers' score of the Center for Epidemiologic Studies Depression Scale (CES-D) score (r = 0.50), as well as a single global rating of burden (r = 0.71). It was also shown that demographic distribution of the score of the Japanese version had a similar trend to that of the original version. Caregivers who looked after patients with behavioral disturbances were found to have a significantly higher ZBI score than those who looked alter patients without behavioral disturbances, which is consistent with previous findings. It is concluded that the Japanese version of the ZBI can be used to measure feelings of burden of caregivers in the Japanese population and can be used for cross-cultural comparison.  相似文献

The PAS-ADD Checklist is a screening instrument specifically designed to help staff recognize mental health problems in the people with intellectual disability for whom they care, and to make informed referral decisions. The instrument consists of a life-events checklist and 29 symptom items scored on a four-point scale. Scores are combined to provide three threshold scores. The crossing of any of these thresholds indicates the need for a fuller assessment. The items are worded in everyday language, making the Checklist suitable for use by individuals who do not have a background in psychopathology. The present paper presents the results of a number of studies evaluating the reliability and validity of the Checklist. Factor analysis of Checklists completed on a community sample of 201 individuals yielded eight factors, of which seven were readily interpretable in diagnostic terms. Internal consistency of the scales was generally acceptable. Inter-rarer reliability in respect to individual items gave a fairly low average Kappa of 0.42. However, agreement on case identification, the main purpose of the Checklist, was quite good, with 83% of the decision being in agreement. Validity in relation to clinical opinion was also satisfactory, case detection rising appropriately with the clinically judged severity of disorder. The PAS-ADD Checklist is published and distributed by the Hester Adrian Research Centre, Manchester, England, from where further information and order forms are available on request.  相似文献
