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.

Abstract Background Coping strategies are essential in the cancer management/recovery process and show an integral part in patients with cancer globally. In Sri Lanka, validated scales to measure coping are scarce. This study was examined the Sinhalese version of the Brief COPE for its psychometric properties. Methods This scale is self-administered (28 items) and consists of adaptive and maladaptive coping strategies; divided into 14 subscales. Cancer patients were registered ‘first come - first serve’ basis using their appointment register at the Radiotherapy Unit, Oncology ward, Teaching Hospital, Karapitiya, Galle, Sri Lanka. They were requested to complete the Sinhalese version of the Brief COPE and demographic details. Test-retest reliability was checked using the same subjects two weeks later. Factorial validity was performed using exploratory factor and principal component analysis. Results were regarded as statistically significant if p < 0.05. Results The mean (±SD) age of the sample was 61(±12) years. The mean adaptive coping (±SD) and maladaptive coping were 37.50 (±8.14) and 17.10 (±2.44) respectively. The internal consistency of the overall scale was good (Cronbach’s alpha - 0.819). Adaptive and maladaptive coping showed a high Cronbach’s alpha (0.861 and 0.396). The test-retest reliability was found to be 0.66. The Sinhala version of BC was found to have a negative correlation with the CES-D scale but was positively correlated with the WHOQOL-BREF questionnaire. Seven factors were extracted. Conclusion The Sinhala version of the Brief COPE is a valid and reliable tool to assess coping strategies among patients with cancer. The findings of this study would let the health authorities get an understanding of coping strategies among patients with cancer; and the impact on cancer victims and family members to relieve their suffering.

PURPOSE The European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire (EORTC QLQ-C30) is a well-validated instrument that assesses health-related quality of life (HRQOL) in cancer patients. It is used in cancer clinical trials in Europe, Canada, and the United States, and has demonstrated high reliability and validity in different groups of cancer patients. Despite thorough testing of reliability and validity, we have not identified any reports on its test/retest reliability; thus, a test/retest study was performed at the Norwegian Radium Hospital (NRH). MATERIALS AND METHODS Cancer patients from the outpatient clinic who were off treatment for > or = 3 months were eligible for the study. The EORTC QLQ-C30 was given to the patients when they presented for their visit. The second questionnaire was received by the patients 4 days later. Of 291 eligible patients, 270 (93%) agreed to participate and 190 (73%) completed both questionnaires. RESULTS The test/retest reliability measured by Pearson's correlation coefficient was high for all functional scales, with a range from .82 for cognitive and role function to .91 for physical function. The r value for global HRQOL was .85. For the symptom scales--nausea/vomiting, fatigue, and pain--the coefficients were .63, .83, and .86, respectively. The single-item coefficients ranged from .72 for diarrhea to .84 for financial impact. The Spearman rank correlation was in the same range for all dimensions. CONCLUSION The EORTC QLQ-C30 seems to yield high test/retest reliability in patients with various cancer diagnoses whose condition is not expected to change during the time of measurement.

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.

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).

Abstract Background Chronic conditions impose a major impact on quality of life and on healthcare. The Assessment of Burden of Chronic Conditions (ABCC-)tool was developed to improve experienced quality of care and quality of life by facilitating shared decision-making and self-management. It assesses the experienced burden of one or multiple conditions, and visualises and integrates the burden in daily care. However, its scale’s validity and reliability are yet unknown. The aim of this study is to evaluate whether the ABCC-scale is valid and reliable in people with Chronic Obstructive Pulmonary Disease (COPD), asthma, or Type 2 Diabetes Mellitus (T2DM). Methods The Saint George Respiratory Questionnaire (SGRQ), the Standardized Asthma Quality of Life Questionnaire (AQLQ-S), and the Audit of Diabetes Dependent Quality of Life Questionnaire (ADDQoL19) were compared to the ABCC-scale to assess convergent validity. Convergent validity was assumed when at least 75% of the postulated correlations were higher than 0.7, or between 0.3 and 0.7 for single-item subscales. To measure known-group validity, participants were categorized according to exacerbation status, depression, asthma control, insulin dependence, complications and obesity. The ABCC-scale was deemed internally consistency upon a Cronbach’s alpha ≥ 0.90 for the total scale, and ≥ 0.70 for subscales. Test-retest reliability was evaluated at a two-week interval. Results A total of 65, 62, and 60 people with COPD, asthma, T2DM respectively were included. The ABCC-scale correlated, in accordance with hypotheses, with the SGRQ (75%), AQLQ-S (100%), and ADDQoL19 (75%). Differentiation of known-groups based on the ABCC-scale was possible for all specified groups. The total score and subscores of the ABCC-scale were internally consistent with a Cronbach’s alpha of 0.90, 0.92, and 0.91 for the total score for people with COPD, asthma, and T2DM respectively. The ABCC-scale had a good test-retest reliability with an Intraclass Correlation Coefficient of 0.95, 0.93, and 0.95 for people with COPD, asthma and T2DM respectively. Conclusions The ABCC-scale is a valid and reliable questionnaire that can be used within the ABCC-tool for people with COPD, asthma or T2DM. Future research should indicate whether this also applies to people with multimorbidity, and what the effects and experiences are upon clinical use.

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.

AbstractBackgroundThe Migraine-Specific Quality of Life Questionnaire version 2.1 (MSQv2.1) is used to evaluate the impact of symptoms on the quality of life (QoL) of migraineurs.ObjectiveTo evaluate primarily the concurrent validity, test–retest reliability, and internal consistency, and secondarily the sensitivity to change of a Thai version of the MSQv2.1.MethodsThe original English version of the MSQv2.1 was translated into a Thai version. The Thai version of the MSQv2.1 was assessed for content and language equivalence. Validity of the Thai version of the MSQv2.1 was assessed using migraine characteristics in a prospective study conducted at the Chulalongkorn Comprehensive Headache Centre of King Chulalongkorn Memorial Hospital. Test–retest reliability and internal consistency were tested in migraineurs. Sensitivity to change was evaluated in another group of migraineurs using an 8-week follow-up.ResultsWe recruited 30 migraineurs to test the validity, test–retest reliability, and internal consistency of the Thai version of the MSQv2.1 and 11 migraineurs to test its sensitivity to change. The Thai version of the MSQv2.1 scores were significantly correlated with migraine symptoms (inverse coefficient range from –0.62 to –0.39) except for associated symptoms, which had no correlation with any of the dimensions or overall QoL score. Spearman’s correlation coefficient for test–retest reliability was 0.56–0.83, and Cronbach’s α for internal consistency was 0.91–0.96. Headache, including average pain duration per attack, pain severity score (numeric rating scale), associated symptoms and dimensions, and overall QoL score of the Thai version of MSQv2.1 improved over time (P < 0.05). Moreover, improvement in headache correlated (coefficient range 0.67–0.77) with improvement in overall QoL score and some dimensions of the Thai version of the MSQv2.1 (coefficient range 0.66–0.77).ConclusionThe Thai version of the MSQv2.1 had validity, acceptable internal consistency, moderate-to-strong test–retest reliability, and strong correlation between improvement in headache severity and overall QoL score. A future study with a larger sample size and longer follow-up is required for better estimates of internal consistency and sensitivity to change.

Abstract Introduction The Thyroid-Related Patient-Reported Outcome (ThyPRO) is a new thyroid-specific quality of life patient-reported outcome measure for benign thyroid disorders. Objective The objective of this study was to investigate the face validity, internal consistency, and test-retest reliability of the Thai version of the ThyPRO (ThyPROth). Methods The translation of the ThyPRO questionnaire was performed using double forward translation, reconciliation, single backward translation, and cognitive debriefing, followed by a panel review. Five thyroid patients evaluated the face validity. The internal consistency and test-retest reliability were evaluated in 30 patients with thyroid diseases. Results The overall validity score was 3.75 (range 0–4). The Cronbach α coefficient ranged from 0.76 to 0.95, with a total coefficient of 0.97 (95% CI 0.962–0.959), indicating excellent internal consistency. The test-retest reliability coefficient ranged from 0.70 to 0.97. All values were 0.70 and above. The total reliability coefficient was 0.86 (95% CI 0.724–0.932), indicating excellent reliability. Conclusion The ThyPROth was found to be valid and to exhibit good internal consistency and test-retest reliability. The questionnaire is ready for implementation in the assessment of health-related quality of life in Thai patients with benign thyroid diseases.
