The Impact

Background: Third-party hearing loss-related quality of life (HLQoL) reports measure the third-party disability as a result of communicating regularly with someone with hearing loss. Scales with known psychometric characteristics validated on a diverse subject population are needed in order to describe the activity limitations and participation restrictions experienced by spouses as a result of living with an individual with hearing loss. Purpose: The purpose of the present study was to develop a scale to measure third-party HLQoL in spouses of people with hearing loss with acceptable psychometric characteristics. This scale is known as the Hearing Impairment Impact–Significant Other Profile (HII-SOP). Research Design: In Study 1, the initial test items were developed and evaluated with a factor analysis for adequate construct validity. In Study 2, the internal consistency reliability, the validity, and the test-retest reliability of the revised test were evaluated. Study Sample: In Study 1, 120 people between 34 and 87 yr of age participated and in Study 2, 164 people between 23 and 88 yr of age participated. Data Collection and Analysis: In Study 1, a 41-item questionnaire was developed based on five content areas: physical adjustment, social activities, emotional reaction, intimate relationship, and change in roles. The scale was submitted to a factor analysis to analyze interrelationships among items, determine the underlying dimensions, and select items for the final scale. In Study 2, the internal consistency reliability, construct validity, and test-retest reliability were evaluated in the revised 20-item questionnaire. The internal-consistency reliability was measured using Cronbach's alpha. Validity was assessed by observing the correlations of the new scale with well-established scales measuring related constructs: overall health-related quality of life, marital communication, HLQoL, and negative affect, in both the person with hearing loss and the spouse. Test-retest reliability was measured in a subset of the spouses who completed the HII-SOP between 2 and 4 wk after the initial scale was completed. Results: The HII-SOP is a 20-item scale with three subscales which measure: (1) the emotions that arise when having a spouse with hearing loss as well as the impact of the hearing loss on the marital relationship, (2) the impact of the hearing loss on the social life of the spouse, and (3) the communication strategies used by the spouse. The scale and its subscales have adequate internal-consistency reliability suggesting that the 20 items do measure a single construct and the subscales do measure distinct subconstructs. The HII-SOP scale was significantly correlated with measures expected to relate to the construct of third-party disability associated with hearing loss. Finally, the HII-SOP scale has adequate test-retest reliability (r = 0.90) and the 95% critical differences is 19.7 points. Conclusions: The HII-SOP is a scale to measure third-party HLQoL in spouses of individuals with hearing loss. Scores of 20–39 reflect mild third-party disability, scores of 40–59 reflect moderate third-party disability, and scores >60 reflect severe third-party disability associated with hearing loss.

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).

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.

SummaryThere has been a growing interest in the quality of life (QoL) of the mentally ill, subsequently a number of instruments to measure QoL have been developed. One of the measures of QoL which has received considerable attention is the Lancashire QoL Profile (LQOLP). The present study investigated test-retest reliability and internal consistency in the Swedish translation of the LQOLP using a cross-sectional sample of 29 inpatients. The results showed that test-retest reliability of subjective life satisfaction in the nine life domains covered by the LQOLP was satisfactory in seven of the domains, and acceptable in two (social relations and religion). Test-retest reliability for total subjective satisfaction score, global well-being, and an interviewer rated QoL were all on a satisfactory level (r > 0.80). The internal consistency and homogeneity of the total subjective QoL scale and the nine life domain subscales was satisfactory except for the social relations scale, where it was somewhat low.

Abstract Background: Religious and spiritual support (RSS) is considered a vital method of coping among patients with cancer and cancer survivors. Measuring religion and spiritual support received by cancer patients has very little evidence in Sri Lanka compared to the western countries. It would be affected on cancer care management and speedy recovery process of cancer patients; could be benefited to reduce long-term suffering of patients with cancer. This study aimed to develop and validate a tool to measure religion and spiritual support in patients with cancer. Methods: WHO guidelines were incorporated into the cross-cultural adaptation of the newly developed religious and spiritual support scale (RSSS). Internal consistency for the overall RSSS was investigated using Cronbach’s alpha. Intra-class correlation coefficient (ICC) was used to examine the test-retest reliability of the RSSS for the same sample. Validity was checked using convergent and divergent validity. Principal component analysis (PCA) was performed to test factorial/construct validity.Results: The Sinhalese version of RSSS showed a high internal consistency (Cronbach’s alpha-0.883). The scale revealed favourable test-retest reliability (ICC = 0.981). The overall RSSS score correlated negatively and positively with depressive symptoms (r= - 0.338, p<0.05) and quality of life scores; overall (r=0.421, p<0.001), physical (r=0.340, p<0.05), psychological (r=0.279, p=0.08), social (r=0.373, p<0.05) and environmental quality of life (r=0.429, p<0.001) confirming satisfactory divergent and convergent validity of the Sinhalese version of the RSSS. Factor analysis with PCA extracted two factors explaining 74.47% of the variance.Conclusions: The Sinhalese version of RSSS is a reliable and valid scale to assess the religious and spiritual support of patients with cancer in Sri Lanka.

The Short Form Qualiveen (SF-Qualiveen) is an 8-item version of the Qualiveen questionnaire used to evaluate the impact of urinary symptoms on the quality of life in patients with urological dysfunction due to neurological disorders. The questionnaire was never available in the Russian language before. The study is aimed at providing the translation, cultural adaptation, and validation of a Russian version of the SF-Qualiveen for the use in patients with multiple sclerosis (MS). Materials and Methods. The original English language version of the SF-Qualiveen was translated into Russian according to the cultural and linguistic adaptation algorithm. The participants (50 MS patients with neurogenic bladder and 10 relatively healthy volunteers) filled out the finalized Russian version of the SF-Qualiveen and the Neurogenic Bladder Symptom Score (NBSS) twice, 2 weeks apart. The data obtained was used to determine the internal consistency (Cronbach’s alpha), external validity (the Spearman correlation), and test-retest reliability (intraclass correlation coefficient (ICC)) of the questionnaire. Results. The mean SF-Qualiveen total score was 2.51±0.79 in patients with a neurogenic bladder and 0.1±0.02 in the control group (p<0.001). Cronbach’s alpha exceeded 0.9 indicating an excellent internal consistency of the questionnaire. The retest did not reveal any significant differences between the findings. The test-retest reliability was good for all items and domains (ICC 0.81-0.89). The total score demonstrated the highest ICC (0.89). The external validity was verified by a strong correlation demonstrated between the SF-Qualiveen and NBSS scores. Conclusions. The Russian SF-Qualiveen questionnaire is a reliable, valid, and consistent tool for the assessment of a urinary disorder impact on the quality of life in patients with MS.

Background: No specific questionnaire that evaluates Health-Related Quality Of Life (HRQOL) in individuals with obesity is available in the Arabic language. The aim of this study was therefore to propose and examine the validity and reliability of an Arabic language version of the ORWELL 97, a validated obesity-related HRQOL questionnaire. Methods: The ORWELL 97 questionnaire was translated from English to Arabic language and administered to 318 Arabic-speaking participants (106 from clinical and 212 from community samples), and underwent internal consistency, test–retest reliability, construct and discriminative validity analysis. Results: Internal consistency and the test–retest reliability were excellent for ORWELL 97 global scores in the clinical sample. Participants with obesity displayed significantly higher ORWELL 97 scores than participants from the community sample, confirming the good discriminant validity of the questionnaire. Confirmatory factor analysis in the clinical sample revealed a good fit for a modified two-factor structure. Conclusion: Overall, the Arabic version of the ORWELL 97 can be considered validated in Arabic adult patients with obesity, paving the way to further assessment of its responsiveness in measuring changes in health-related quality of life associated with obesity treatment.

The Impact

Purpose The Voice Handicap Index (VHI) questionnaire assesses the impact of total laryngectomy on voice-related quality of life. This study evaluates the Mandarin VHI, including its internal consistency, test–retest reliability, content validity, and differences in scores for Mandarin alaryngeal patients with pneumatic artificial laryngeal (PA) and esophageal (ES) speech. Method Translation and validation of the VHI questionnaire was performed through the forward–backward translation technique. This study used a sample of 78 PA and 23 ES participants from Taiwan who completed the Mandarin VHI. Forty-two of the alaryngeal participants completed the Mandarin VHI twice over a period of 7–63 days. Results The measurement of the internal consistency of the Mandarin VHI showed a high Cronbach's alpha coefficient for the total score (.975) and the functional (.930), physical (.939), and emotional (.938) subscales. Based on the results of the intraclass correlation coefficients, good test–retest reliability for the total and domain scores was found (intraclass correlation coefficient = .827–.863). Conclusion The Mandarin VHI was validated as an instrument with proper internal consistency and reliability, which supports the Mandarin VHI as a valid instrument for the self-evaluation of handicaps related to voice problems in PA and ES speakers.

Background: The Western Ontario Rotator Cuff Index (WORC) is an assessment tool developed to evaluate quality of life in patients with rotator cuff disease (RCD). The purpose of this study is to translate the WORC index into Spanish and to evaluate its reproducibility and internal consistency in patients with RCD. Methods: Following guidelines from literature, the WORC index was translated. Sixty patients with RCD were asked to complete the questionnaire. To evaluate reliability, they were asked to answer it for a second time within the next 14 days. The Cronbach’s α (CA) and the intraclass correlation coefficient (ICC) were calculated to determine test-retest reliability and internal consistency. Bland-Altman plot and reliable change index (RCI) were used to evaluate measurement error. Results: Cronbach’s α was 0.96 for the total WORC score (ranges 0.85-0.94 for the five domains).Excellent test-retest reliability was seen with an ICC of 0.98, with the domains ranging between 0.91-0.97. The Bland-Altman plot showed no systematic differences, and the RCI for the total WORC index was 7.6%. Conclusion: The Spanish version of the WORC index is a valid and reliable tool for evaluating quality of life in patients with RCD and may be used in Spanish speaking countries like Colombia. Level of evidence: Basic Science Study, Development or Validation of Outcomes Instruments/Classification Systems.

<b><i>Introduction:</i></b> Valid assessments of quality of life (QoL) and cognition are important in caring for individuals with severe dementia; there is an urgent need for validated assessment tools for specific populations. This study aimed to develop and validate Chinese versions of the Quality of Life in Late-Stage Dementia (QUALID-C) scale and the Cognitive Test for Severe Dementia (CTSD-C) for Chinese older adults. <b><i>Methods:</i></b> This was a cross-sectional validation study comprised of 93 Chinese older adults with severe dementia recruited from 6 residential homes. The content and cultural validity of the QUALID-C and CTSD-C were evaluated by a 7-member expert panel, and interrater reliability, test-retest reliability, internal consistency, concurrent validity, and factorial structure were examined. <b><i>Results:</i></b> The QUALID-C showed acceptable internal consistency (Cronbach α = 0.65), good interrater reliability (intraclass correlation coefficient [ICC] = 0.99), and good test-retest reliability (ICC = 0.96). Principal component analysis yielded 3 factors; the items loaded on the factors were comparable to those in previous studies and suggested the scale’s multidimensionality to measure QoL. The CTSD-C showed satisfactory internal consistency (Cronbach α = 0.862), good interrater reliability (ICC = 0.99), and good test-retest reliability (ICC = 0.958). Principal component analysis yielded 3 factors; the items loaded on factors 1 and 2 resembled the items of the automatic response and attentional control factors of the original study. <b><i>Conclusion:</i></b> The QUALID-C and the CTSD-C are reliable and valid scales to measure the QoL and cognitive functions of Chinese older adults with severe dementia. These assessments can be utilized to evaluate the effectiveness of treatment and future research work.
