If self-referent instruments about people’s health are to be useful in clinical and research settings, those instruments must be developed according to well-established processes and principles of measurement. We outline the main processes that should occur in the development of self-referent measuring instruments in general, with a focus, for illustrative purposes, on those intended to assess foot health. Requirements and issues concerning different forms of reliability and validity receive the most attention. In particular, problems associated with indices of test-retest reliability, inter-item homogeneity, and construct validity are identified and discussed. Practicalities concerning administration and scoring are also considered. A list of questions is provided for prospective users to assess the characteristics and quality of self-referent instruments.

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).

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.

Linguistic, reliable, and valid secondary efficacy measures are important in clinical settings and studies. The aim of the study is to report test–retest reliability and construct validity of Turkish version of Myasthenia Gravis-Activities of Daily Living Scale (MG-ADL-T) in Myasthenia Gravis (MG) patients. Fifty-two ocular and generalized individuals with MG, applying to rehabilitation center, were included in the study. MG-ADL-T, MG quality-of-life questionnaire (MG-QoL), MG composite (MGC), quantitative MG score (QMGS), and pulmonary function test were administered. Reliability was assessed with intraclass correlation coefficient (ICC) and Cronbach’s alpha. Spearman correlation test and receiver operating characteristic (ROC) analysis were performed for construct validity. MG-ADL-T had fair internal consistency (Cronbach’s α = .67), excellent test–retest reliability (ICC = 0.96) and moderate construct validity (MG-QoL, r = 0.59; QMGS, r = .58; MGC, r = .68). MG-ADL, a unique scale that evaluates activities of daily living (ADL), has good test–retest reliability and construct validity in Turkish MG patients.

Emotional Style

Until recently, emotional processes have played little role in personality psychology. Based on neuroscientific findings, Davidson and colleagues proposed a theory of emotional styles, postulating six dimensions of emotional life: outlook, resilience, social intuition, self-awareness, sensitivity to context, and attention. Recently, an English version of the Emotional Style Questionnaire (ESQ) was developed and tested for reliability and validity. The aim of the present work was to test the test–retest reliability, internal consistency, construct validity, and criterion validity of the German version of the ESQ. Two separate samples consisting of 365 and 344 subjects took part in an online survey. The results of the two studies indicated satisfactory test–retest reliability and internal consistency. Regarding the construct validity, the results from Study 1 to Study 2 indicate good model fit indices. Although there was a high correlation between the subscales outlook and resilience, the analyses supported the six-factor structure postulated by Davidson and colleagues. Substantial correlations were found between the dimensions of the ESQ and other validated scales, confirming the criterion validity of the questionnaire. Our results suggest that the German version of the ESQ is a reliable and valid measurement of emotional styles. It is a feasible and economical questionnaire that can be applied in various psychology disciplines, such as personality psychology, clinical psychology, industrial psychology or sport and exercise psychology.

Abstract Background Hypoparathyroidism (HP) is a rare endocrine disorder characterized by absent or inappropriately low levels of circulating parathyroid hormone with associated significant physical and cognitive symptoms. This study evaluated the psychometric properties of the Hypoparathyroidism Patient Experience Scales (HPES), which were developed as disease-specific, patient-reported outcome (PRO) measures to assess the symptoms and impacts associated with HP in adults. Methods Data from a non-interventional, observational study (N = 300) and a Phase 2 clinical trial (N = 59) were used in the psychometric evaluation. Observational and trial assessments included: an online validation battery (baseline or screening) and retest (approximately 2 weeks after baseline or screening). In the trial, the primary efficacy endpoint was assessed at week 4 through re-administration of the HPES and validation battery subset. The observational study’s larger sample size allowed for evaluation of the HPES descriptive properties, scoring algorithm, test-retest reliability, and construct validity. The trial data examined responsiveness, meaningful within-patient change estimates, and treatment impact on HPES scores. Results Demographic and self-reported medical characteristics results were similar across the 2 studies. Factor analysis confirmed domains in the HPES-Symptom (n = 2) and HPES-Impact (n = 4). For both measures, total and domain scores demonstrated acceptable reliability and validity for both the observational and trial samples. Internal consistency evidence was strong. Test-retest reliability estimates generally approached the recommended 0.70 threshold. The construct validity correlations with other PRO measures were mainly as hypothesized, thus supporting the HPES scores and constructs. Mean scores for both measures also differed as anticipated and significantly across known-groups, thus providing evidence for the scores discriminating between meaningful groups. Trial results supported both HPES total and domain scores’ ability to detect change. The difference in mean total and domain scores for both measures demonstrated statistically significant improvements for TransCon PTH compared to placebo treated subjects despite the small sample and a short 4-week duration on fixed, non-optimized doses. Conclusions The HPES were found to be conceptually sound with adequate evidence supporting their reliability and validity. Incorporation of the HPES into clinical and research settings will help to further elucidate and assess the patient experience of living with HP and identify treatment differences.

Abstract Background This study aimed to validate the translation of the Sinus and Nasal Quality of Life Survey (SN-5) into Arabic (SN-5a) in pediatric chronic rhinosinusitis (CRS) patients. A prospective cohort randomized controlled study was conducted on 129 children with CRS and 100 age- and sex-matched healthy children. The questionnaire was translated into the Arabic language with cross-cultural adaptation. Caregivers answered the questionnaire during their first visits and after 1 week; to assess test–retest reliability and after 2 weeks of medical treatment to test the questionnaire’s ability to detect changes in patients’ symptoms. The responses of the patients and control groups were compared to assess the external validity. Results The SN-5a showed internal consistency and reliability, with Cronbach’s alpha value being 0.69. Item–item and item–total correlation analysis showed adequate construct validity with a highly significant negative correlation between the SN-5 questionnaire items and visual analog scale (VAS) (p < 0.001). There were highly significant positive correlations between items of the questionnaire in the 1st and 2nd visits at 1 week (p < 0.001). A highly significant difference between the case and control groups had been shown for all SN-5a items (p < 0.001). Two weeks after treatment, there were large changes in all the questionnaire items between the first and last visits (effect size > 0.8 for all). Conclusion The translated SN-5a exhibited adequate construct validity, internal consistency, test–retest reliability, and external validity with quite enough ability to assess the longitudinal changes of the disease.

AbstractObjective:This project evaluated the psychometric properties of a translated version of the Head and Neck Cancer Inventory (HNCI) for use with Japanese patients. The HNCI is a measure for assessing the quality of life (QoL) of head and neck cancer patients and survivors. The present study was aimed at investigating the reliability and validity of this translated instrument.Method:Some 165 patients with head and neck cancer (HNC) were enrolled at the Tokyo Medical and Dental University Hospital. The instrument's internal consistency and test–retest reliability were evaluated. Criterion-related validity was assessed by correlations between the HNCI and the Functional Assessment of Cancer Therapy–Head and Neck (FACT–H&N) scales.Results:Some 29 of the 30 items in the original version were selected to comprise the Japanese version of the HNCI (Japanese HNCI). Investigation of criterion-related validity using the FACT–H&N demonstrated significant correlations (Spearman's ρ = 0.47–0.63). The value of Cronbach's α for each subscale ranged from 0.84 to 0.87. Test–retest reliability showed an intraclass correlation coefficient (ICC) of 0.62–0.79.Significance of Results:The reliability and validity of the Japanese HNCI were evaluated. Although its classification is different from the original U.S. version, the Japanese HNCI is a self-administered questionnaire that can assess quality of life (QoL) in patients with head and neck cancer.

AbstractThe Dysphagia Handicap Index (DHI) is a valid Health-related Quality of Life (HRQOL) questionnaire for patients with oropharyngeal dysphagia (OD) of heterogeneous etiologies. The study aimed at crossculturally translating and adapting the DHI into Italian (I-DHI) and analyzing I-DHI reliability, validity, and interpretability. The I-DHI was developed according to Beaton et al. 5-stage process and completed by 75 adult OD patients and 166 healthy adults. Twenty-six patients filled out the I-DHI twice, 2 weeks apart, for test–retest reliability purposes. Sixty-two patients completed the Italian-Swallowing Quality of Life Questionnaire (I-SWAL-QoL) for criterion validity analysis. Construct validity was tested comparing I-DHI scores among patients with different instrumentally assessed and self-rated OD severity, comparing patients and healthy participants and testing Spearman’s correlations among I-DHI subscales. I-DHI interpretability was assessed and normative data were generated. Participants autonomously completed the I-DHI in maximum 10 min. Reliability proved satisfactory for all I-DHI subscales (internal consistency: α > .76; test–retest reliability: intraclass correlation coefficient > .96, k = .81). Mild to moderate correlations (− .26 ≤ ρ ≤ − .72) were found between I-DHI and I-SWAL-QoL subscales. Construct validity proved satisfactory as (i) moderate to strong correlations (.51 ≤ ρ ≤ .90) were found among I-DHI subscales; (ii) patients with more severe instrumentally or self-assessed OD reported higher I-DHI scores (p < .05); and (iii) OD patients scored higher at I-DHI compared to healthy participants (p < .05). Interpretability analyses revealed a floor effect for the Emotional subscale only and higher I-DHI scores (p < .05) for healthy participants > 65 years. In conclusion, the I-DHI is a reliable and valid HRQOL tool for Italian adults with OD.
