Aging Males Symptoms

This study was to assess whether the Chinese version of the Aging Males' Symptoms scale could measure aging men's symptoms as effectively as the English version. 176 psychiatric outpatient men were assessed to analyze internal consistency reliability and construct validity, and 45 male school staff were interviewed in estimating retest reliability. Cronbach a was .90, and the 3-wk. retest reliability was .72. Factor analysis yielded a two-factor structure. Construct validity was indicated by significant correlation between the two factors and the criterion variables. This scale is a validated and sensitive test for measuring symptoms in aging men in the Taiwanese Chinese-speaking population. It is suggested that the scale could be used to measure and compare health-related quality of life in groups of men over 40 years old.

Purpose The construct validity of the Voice-Related Quality of Life (V-RQOL; Hogikyan & Sethuraman, 1999) measure was evaluated in a sample of 109 individuals who have undergone total laryngectomy. Method A principal components factor analysis was performed on participant responses to the 10-question V-RQOL measure. Results Factor analysis of the V-RQOL in our alaryngeal sample confirmed the presence of two factors (physical and social–emotional), which is consistent with the identified domains in the current V-RQOL. However, the current data indicate that some of the questions proposed by the original authors of the V-RQOL (Questions 7 and 9) do not align with their proposed domains in this postlaryngectomy sample. Conclusion The results indicate that some V-RQOL questions do not align with their proposed domains. Consequently, an alternative scoring algorithm may be warranted for alaryngeal populations, and the authors make suggestions for this change that are simple and efficient. Based on the findings of the present factor analysis, use of this modified scoring procedure may serve to increase the sensitivity of the V-RQOL for those who are laryngectomized and use alaryngeal methods of voice and speech. Consequently, the value and application of the V-RQOL may be expanded in the clinical setting.

Test Retest Reliability

Background:The Orthotics and Prosthetics Users’ Survey consists of five modules to assess outcomes of orthotic and prosthetic interventions: lower extremity functional status, upper extremity functional status, client satisfaction with device, client satisfaction with services and health-related quality of life.Objectives:To investigate the test–retest reliability and calculate the smallest detectable difference for all modules of the Swedish Orthotics and Prosthetics Users’ Survey.Study design:Test–retest reliability study design.Methods:A total of 69 patients at a Department of Prosthetics and Orthotics completed Orthotics and Prosthetics Users’ Survey on two occasions separated by a 2-week interval, giving 18 answers on lower extremity functional status, 41 on upper extremity functional status, 53 on client satisfaction with device, 12 on client satisfaction with services and 67 answers on health-related quality of life. Raw scores were converted into Orthotics and Prosthetics Users’ Survey units on a 0–100 scale. Intra-class correlation coefficients, Bland–Altman plots, common person linking plots and t-tests of person mean measures were used to investigate the reliability. The 95% confidence level smallest detectable differences were calculated.Results:The intra-class correlation coefficients ranged from 0.77 to 0.96 for the modules, and no systematic differences were detected between the response occasions. The smallest detectable differences ranged from 7.4 to 16.6 units.Conclusions:The test–retest reliability was satisfactory for all Orthotics and Prosthetics Users’ Survey modules. The smallest detectable difference was large on all modules except the health-related quality of life module.Clinical relevanceThe Orthotics and Prosthetics Users’ Survey modules are reliable and, thus, can be recommended for repeated measurements of patients over time. Relatively large changes are needed to achieve statistical significance when assessing individual patients.

Test Retest Reliability

Objective: To test the Brazilian Portuguese velopharyngeal insufficiency (VPI) Effects on Life Outcome (VELO) instrument for reliability and validity. Design: Cross-sectional methodological study. Setting: Tertiary craniofacial medical center. Participants: Participants with VPI (VPI group, n = 60), with cleft and without VPI (no VPI/cleft group, n = 60), and with no cleft nor VPI (no VPI/no cleft group, n = 60) and their parents (n = 180). Interventions: All patients with VPI 8+ years old and their parents completed the Brazilian–Portuguese VELO instrument and other questionnaires (Pediatric Quality of Life Inventory4.0, PedsQL4.0; Pediatric Voice-Related Quality of Life, PVRQOL; and Intelligibility in Context Scale, ICS) at baseline; patients with VPI and their parents completed the VELO instrument again 2 weeks later. Main Outcome Measures: The VELO instrument was tested for internal consistency, test–retest reliability, discriminant validity (participants with VPI against participants with no VPI), concurrent validity against other questionnaires, criterion validity against hypernasality severity, and construct validity against nasal air emission and overall velopharyngeal competence (speech construct) and velopharyngeal gap (anatomic construct). Results: The VELO had excellent internal consistency (Cronbach α 0.99 for parents and 0.98 for participants with VPI) and test–retest reliability (all intraclass correlation coefficient > 0.87). The VELO discriminated well between VPI group and unaffected groups (all P < .05). The VELO was significantly correlated with the PedsQL4.0, PVRQOL, and ICS (– r > 0.75; P < .001). The VELO met criterion validity, speech construct validity, and anatomic construct validity ( r > 0.7; P < .001). Conclusions: The Brazilian-Portuguese VELO instrument demonstrated reliability (internal consistency and test–retest) and validity (discriminant, concurrent, criterion, and construct).

Health-related quality of life measurements are gaining more importance in the study and clinical practice of multiple sclerosis. The aim of our study was the adaptation of the Multiple Sclerosis Quality of Life Instrument (MSQOL-54) in Hungarian. The study was carried out at the Department of Neurology, University of Szeged and two other multiple sclerosis centers. The Hungarian translation of the questionnaire was given to patients at the outpatient units of the neurology departments. The EDSS score of the patients were determined and data concerning the onset and the clinical form of the disease was collected. Altogether 438 patients filled out the questionnaire. We enrolled patients with all clinical forms of the disease. Cronbach's alpha coefficients were over 0.8 in case of all scales except `Rolelimitations — emotional' (0.794), indicating a good internal consistency reliability for group comparisons. The instrument was able to distinguish between known clinical group differences. The Hungarian version of the MSQOL-54 instrument shows good psychometric properties similar to the original questionnaire. Multiple Sclerosis 2008; 14: 391—398. http://msj.sagepub.com
