PURPOSE: The psychometric properties of the Dutch version of the Washington Psychosocial Seizure Inventory (WPSI) were investigated. METHODS: The dimensional structure, reliability, and validity of the WPSI scales were assessed in 218 patients with epilepsy. The association with relevant patient and epilepsy characteristics also was studied. RESULTS: An exploratory seven-factor principal components analysis was compared with a confirmatory factor analysis, and a loss of 3.36% of total variance was found. To increase the homogeneity of the scales, 30 items with low factor loadings or highest factor loading on the wrong clinical scale were excluded. This resulted in a higher amount of explained variance and improvement of the factor loadings of the remaining items. The reliability and validity of the WPSI scales was satisfactory to good. No clinically relevant associations were found between the WPSI scales and patient and epilepsy characteristics. CONCLUSIONS: The factor structure, reliability, and validity of the Dutch translation of the WPSI are good and comparable to the original English version of Dodrill. The results demonstrate that shortening the WPSI makes the inventory more reliable and the clinical scales less dependent on each other.  相似文献

OBJECTIVE: To assess the psychometric properties of the Spanish version of the Hospital Anxiety and Depression Scale(HADS). METHOD: We administered HADS to 685 participants (256 controls and 429 patients with five different diagnoses). The reliability of the instrument was assessed by a test-retest study. Construct validity studies were carried out through item-subscale correlation and factor analysis for the whole group and by each of the five different diagnoses. Three instruments were used as external criteria to assess concurrent validity. RESULTS: HADS test-retest reliability presented correlation coefficients above 0.85. The internal consistency was high, with a Cronbach's alpha of 0.86 (anxiety) and 0.86 (depression). Factor analysis showed a clear two-factor structure for all groups. The results showed high concurrent validity with the Beck Depression Inventory and State-Trait Anxiety Inventory and with the mental domains of the Short-Form Health Survey. CONCLUSION: The Spanish version of the HADS demonstrated good reliability and validity when used in medical patients.  相似文献

Summary: Purpose: Few data exist on the ability of instruments to detect within-patient change over time in epilepsy, a property referred to as responsiveness. Our aim was to compare the responsiveness of three instruments [i.e., Epilepsy Surgery Inventory-55 (ESI-55) and Washington Psychosocial Inventory (WPSI), both epilepsy specific, and Symptom Checklist-90–Revised (SCL-90–R), non-epilepsy specific]. Methods: Instruments were administered at baseline and at 1 year in a prospective cohort of surgically (43) and medically (14) treated patients with temporal lobe epilepsy. Coefficient of Responsiveness and relative efficiency were computed for each scale and for the dimensions of mental health, physical health, and role function. Results: The ESI-55 contained the most responsive scales, whereas SCL-90–R contained the largest number of scales with moderate responsiveness. The largest number of scales with low responsiveness belonged to the WPSI. Sensitivity to between-treatment differences in change was highest for ESI-55 and SCL-90–R. The most efficient scales in detecting differences between treatment groups in the mental, physical, and role-function dimensions were ESI-55 emotional well-being, ESI-55 health perceptions, and SCL-90–R hostility, respectively. Conclusions: Our results support the responsiveness of ESI-55 scales and suggest that SCL-90–R is a responsive tool for the assessment of psychologic function and distress in epilepsy. Comparatively, WPSI is relatively unresponsive to small or medium-size changes.  相似文献

The assessment of social functioning takes on special importance with the development of promising new types of psychosocial intervention for the treatment of schizophrenia. Nevertheless, there are still few satisfactorily reliable instruments for the assessment of social functioning that are reasonably applicable in terms of time. This scarcity is even more notable in the Spanish language. The aim of this study is to validate a Spanish version of the Social Functioning Scale (SFS) giving new data (test-retest stability and concurrent validity) on the psychometric characteristics of the scale. One hundred and fifty subjects with a diagnosis of functional psychosis according to the DSM-III-R (codes 295-298) criteria - 105 (70%) of them schizophrenic patients - in an outpatient regimen of the Community Mental Health Center were assessed using a Spanish version of the Social Functioning Scale. The reliability and validity of the scale were studied. Data on the reliability (internal consistency, item-total correlation, test-retest and informant/self-report reliability) and validity (of the construct, concurrent and the criterion group method) revealed a substantial fulfillment of the basic psychometric criteria. The results corroborate the favorable psychometric characteristics of the scales and support the worth of the instrument for the assessment of the social functioning of psychotic patients when there is reliable and feasible assessment of out-patients.  相似文献

ObjectivesThe purpose of this study is to develop a self-administered version of the Health of the Nation Outcome Scales for Older Adults (HoNOS65+) in Spanish – the HoNOS65+A – and to study its reliability and validity.MethodsThere are two phases in the study: construction of the HoNOS65+A and the study of its psychometric properties. In the second phase, 179 users of 10 services for older people of Madrid were interviewed. They completed the HoNOS65+A, the Spanish version of the HoNOS65+, and other instruments that evaluate similar constructs. Reliability (internal consistency with the other-administered HoNOS65+, intraclass) and validity (concurrent, discriminant, and criterion validity) were analyzed.ResultsHigh reliability indexes (intraclass correlation coefficients) were found for all the scales (HoNOS65+ and HoNOS65+A), except for items 4 and 6. Moreover, the HoNOS65+A has satisfactory concurrent (except 4, 6, and 9) and discriminant validity (except for items 4 and 10). Considering all these data and some theoretical points the items 4 and 6 have eliminated from the scale. Upon eliminating items 4 and 6, the analysis of the reliability (Cronbach's Alpha) and criterion validity (discriminant function among autonomous and assisted people) presents positive values.ConclusionThe results indicate that the HoNOS65+A is a useful measure that does not assess a homogeneous area but instead different aspects of health and psychosocial functioning.  相似文献

BackgroundThe Schedules for Clinical Assessment in Neuropsychiatry (SCAN) is a set of clinical assessment instruments developed under the auspices of WHO. In contrast to other structured diagnostic interviews, SCAN also provides possibilities for dimensional assessment of psychopathology. This paper reports cross-national findings on the psychometric properties of psychopathology scales derived from SCAN 2.1.MethodsWithin a randomized controlled trial, SCAN 2.1 was used in Dresden (Germany), Michalovce (Slovak Republic), Prague (Czech Republic), and Wrocław (Poland). Forty-seven items from Part I of SCAN 2.1, identified as qualifying for constructing dimensional measures, were, on the one hand, grouped according to their allocation to five specific SCAN 2.1 sections. On the other hand, principal component analyses were used to group the items according to their statistical relationship. To estimate the reliability of the scales, Cronbach's α was computed. To assess factor similarity across sites, Tucker's congruence coefficients were calculated. To appraise concurrent validity, mean scale scores were compared across different diagnostic groups.ResultsReliability was qualified as moderate to substantial for all generated scales. Factor-solutions differed across sites. Differences in mean scores supported the assumption that the scales might possess, in addition to face validity, concurrent validity.ConclusionsThis is the first cross-national study on the psychometric properties of psychopathology scales derived from SCAN 2.1, and findings are very encouraging concerning its use as a dimensional measure. However, further studies are needed to substantiate implementation of the scales established.  相似文献

Objective: To assess classical psychometric properties of the Spanish versions of the Bech‐Rafaelsen’s mania (MAS) and melancholia (MES) scales. Method: Observational, prospective, and multicentric study in bipolar out‐patients. Convergent validity was assessed against the Young Mania Rating Scale and the Montgomery‐Åsberg Depression Rating Scale. Discriminant validity, reliability, and sensitivity to change, were also assessed. Results: One hundred and thirteen bipolar patients with a manic episode and 102 bipolar patients with a depressive episode were included. Both the MAS and the MES showed appropriate convergent validity (r > 0.90), discriminant validity (P < 0.0001), internal consistency (Cronbach’s alpha >0.80), test–retest reliability [intraclass correlation coefficient (ICC) = 0.69 for the MAS and 0.94 for the MES], inter‐rater reliability (ICC > 0.80), and sensitivity to change at 4 weeks since inception (P < 0.0001; within‐group effect size ≥1.8). Conclusion: The Spanish versions of both scales present appropriate psychometric estimates in bipolar patients treated in ambulatory care.  相似文献

OBJECTIVE: The Screen for Cognitive Impairment in Psychiatry (SCIP) is a brief scale designed for detecting cognitive deficits in several psychotic and affective disorders. This study examined the psychometric properties of the Spanish version of the SCIP in a sample of outpatients suffering schizophrenia-spectrum disorders. METHODS: Psychometric properties were evaluated in a sample of 126 stable patients with schizophrenia. Men and women 18 to 55 years of age were recruited from consecutive admissions to 40 psychiatric outpatient clinics in Spain and asked to complete a series of cognitive measures at baseline, as well as three versions of the SCIP separated by one week intervals. A matched sample of 39 healthy controls was also subjected to the baseline examination. The feasibility, reliability and validity of the SCIP was examined; concurrent validity was assessed by means of a complete neuropsychological battery. RESULTS: Average time for SCIP administration was 16.02 (SD=5.01) minutes. Test-retest reliability intra-class correlation coefficients ranged from 0.74 to 0.90, with an internal consistency Cronbach's alpha value of 0.73. The three parallel forms of SCIP were shown to be equivalent. The SCIP scales were correlated with corresponding neuropsychological instruments, with Pearson's r between 0.38 and 0.60, p<0.01. The SCIP effectively discriminated between the patient and control samples. Factor analysis revealed one significant dimension, cognitive performance, that accounted for 49.8% of the total variance. CONCLUSIONS: The Spanish version of the SCIP is a simple, brief, valid and reliable tool for detection of cognitive impairment in patients with schizophrenia by minimally trained healthcare personnel.  相似文献

BACKGROUND: The Six factor Test (SFT) is a personality questionnaire for assessment of the "big five" (neuroticism, extraversion, conscience, aggressivity, openness to experiences) and piety in patients with mental disorders and healthy subjects. METHODS: In a study of 360 probands (125 depressive and bipolar patients, 150 first-degree relatives of these patients, and 85 controls), the reliability and validity of the SFT was examined. Thirty-five controls and 79 relatives were reinvestigated after around 6.5 years. RESULTS: The factorial structure could be replicated, and the concurrent validity was moderate to high. Acceptable internal consistency was observed, with the exceptions of "openness" and "agreeableness". The retest reliability was high, with the exception of "openness". Patients differed from controls in neuroticism and "openness". These factors were also predictive for the first onset of psychiatric disorders in controls and relatives, respectively. CONCLUSION: The SFT is a short und simple instrument for the assessment of personality in clinical samples and controls. Reliability and validity of the three main scales (neuroticism, extraversion, and conscience) were acceptable. The corresponding coefficients of the three shorter scales, in particular of openness, were partly much lower.  相似文献
