Aim: To translate the Quality of Life in Late-Stage Dementia (QUALID) Scale into Norwegian, and to evaluate the test-retest reliability and validity of the scale. Method: QUALID was translated according to standardised procedures. Residents with dementia living in nursing homes were included in the study and assessed using QUALID, Cornell Scale for Depression in Dementia, Neuropsychiatric Inventory, Physical Self-Maintenance Scale and Clinical Dementia Rating Scale. Results: Cronbach's α of QUALID was 0.79. In the reliability study, the intra-class correlation was 0.83. The validity study showed a strong association between depressive symptoms and QUALID, and a moderate association between QUALID and assessments of level of functioning and agitation. Conclusions: The Norwegian version of QUALID is a reliable and valid scale for assessing quality of life in nursing home residents with dementia.

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.

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 Well-adapted and validated quality-of-life measurement models for the nursing home population are scarce. Therefore, the aim of this study was to test the psychometrical properties of the OPQoL-brief questionnaire among cognitively intact nursing home residents. The research question addressed evidence related to the dimensionality, reliability and construct validity, all of which considered interrelated measurement properties. Methods Cross-sectional data were collected during 2017–2018, in 27 nursing homes representing four different Norwegian municipalities, located in Western and Mid-Norway. The total sample comprised 188 of 204 (92% response rate) long-term nursing home residents who met the inclusion criteria: (1) municipality authority’s decision of long-term nursing home care; (2) residential time 3 months or longer; (3) informed consent competency recognized by responsible doctor and nurse; and (4) capable of being interviewed. Results Principal component analysis and confirmative factor analyses indicated a unidimensional solution. Five of the original 13 items showed low reliability and validity; excluding these items revealed a good model fit for the one-dimensional 8-items measurement model, showing good internal consistency and validity for these 8 items. Conclusion Five out of the 13 original items were not high-quality indicators of quality-of-life showing low reliability and validity in this nursing home population. Significant factor loadings, goodness-of-fit indices and significant correlations in the expected directions with the selected constructs (anxiety, depression, self-transcendence, meaning-in-life, nurse-patient interaction, and joy-of-life) supported the psychometric properties of the OPQoL-brief questionnaire. Exploring the essence of quality-of-life when residing in a nursing home is highly warranted, followed by development and validation of new tools assessing quality-of-life in this population. Such knowledge and well-adapted scales for the nursing home population are beneficial and important for the further development of care quality in nursing homes, and consequently for quality-of-life and wellbeing in this population.

Objectives: This systematic review aimed to explore the acceptability, reliability, and validity of the Stroke and Aphasia Quality of Life-39 (SAQOL-39) scale across languages. Data sources: We employed a systematic search of the online databases including MEDLINE (Pubmed), Science direct, Web of science, Psychinfo, Scopus, ProQuest, Google Scholar, and Cochrane library published between 2003 and 2016. Review methods: We used PRISMA guidelines for conducting and reporting this review. Subsequently, screening of the titles and abstracts, extraction of data as well as the appraisal of the quality of relevant studies were carried out. Results: The initial search returned 8185 studies. Subsequent screening and study selection processes narrowed them to 20, needing detailed review. Forward-backward translation scheme was the preferred method for translation of the SAQOL-39 from English to other languages. Mainly, the socio-cultural and linguistic adaptations were performed in the translated versions. Most versions of the SAQOL-39 showed high test-retest reliability and internal consistency. However, several psychometric properties including the validity and responsiveness were seldom reported in these versions. Conclusion: The SAQOL-39 scale showed high acceptability, and reliability across the languages reviewed in this study. Future translations may additionally focus on reporting the validity and responsiveness of the instrument.

Background: The brief generic Multicultural Quality of Life Index (MQLI) is a culturally informed self-report 10-item questionnaire used to measure health-related quality of life (QoL). QoL is an important outcome measure in guiding healthcare and is held as a substantial parameter to evaluate the effectiveness of healthcare. Attention Deficit Hyperactivity Disorder (ADHD) in children might negatively influence the parents’ QoL. Having a validated questionnaire to measure QoL for this population will therefore be a vital first step in guiding healthcare for parents of children with ADHD. We aimed to examine the reliability and validity of the Norwegian version of the MQLI in a sample of parents of children with ADHD.Methods: In a cross-sectional study, 128 parents of children with ADHD were recruited from four outpatient clinics within the Child and Adolescents Mental Health Services (CAMHS) in Norway. They completed the MQLI along with an alternative well-being scale, the Five-item World Health Organization Well-being Index (WHO-5), and a form including demographic variables. Reliability and validity of the MQLI were examined. We conducted a factor analysis and calculated internal consistency and the correlation between the MQLI and the WHO-5.Results: Factor analysis of the parents reported MQLI yielded a one-factor solution. For the MQLI, Cronbach’s alpha was 0.73. The correlation between the two measures of MQLI and WHO-5 was high (r = 0.84), reflecting convergent validity since the association between the two measures was strong.Conclusion: Results from this study support the reliability and validity of the Norwegian version of the MQLI for assessment of quality of life in parents of children with ADHD with good psychometric properties. Study findings support the use of the questionnaire in CAMHS.

SummaryThe joint development of the Dutch and English versions of the Quality of Life in Depression Scale (QLDS) is described. The QLDS is based on the needs model of quality of life developed by Hunt and McKenna. The scale has good reliability and internal consistency. Test-retest correlation coefficients were 0.94 and 0.87 in the United Kingdom and the Netherlands, respectively. Internal consistency alpha-coefficients were 0.95 and 0.92, respectively. The validity of the scale is highly acceptable. The QLDS was shown to correlate relatively highly with established measures of well-being, and scores obtained with the measure were related to severity of depression as assessed by the Hamilton Rating Scale for Depression. The QLDS was shown to be responsive to change in an open study with fluoxetine in 540 patients with major depression. The scale has wide applicability and has been shown to be user-friendly, both for respondents and administrators. It has been, or is in the process of being, tested for reliability and validity in the following additional countries: Australia, Austria, Belgium, Canada, Denmark, France, Germany, Italy, Morocco, Spain and the United States.
