Which is the most useful patient-reported outcome in femoroacetabular impingement? Test–retest reliability of six questionnaires

Background/Aims This article details how a patient-reported outcome measure (PROM), termed PROM-CR1, was tested for acceptability, validity and test-retest reliability at the end of an outpatient cardiac rehabilitation programme. Methods PROM-CR1 was completed by 138 service users (mean age 66.95 years, range 42–94 years; 115 males, 23 females; with a range of cardiac diagnoses), who used the tool at home twice: once at the end of the outpatient cardiac rehabilitation programme and 1 week later. Results PROM-CR1 demonstrated good acceptability, construct and concurrent validity, and test-retest reliability. The construct validity analysis highlighted that one item required removal from the PROM-CR1. Conclusions A finalised 30-item version of the tool will now be widely disseminated and further evaluated within cardiac rehabilitation clinical practice.

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.

Introduction: This study explored the psychometric properties of the modified Harris Hip Score-Greek version (mHHS-Gr) as a patient-reported outcome (PRO) measure in osteoarthritic hip patients. Methods: Internal consistency, test-retest reliability and reproducibility were evaluated in 90 patients aged >55 years. Construct validity was tested against Greek versions of the Lower Extremity Functional Scale (LEFS-Greek) and WOMAC Index (WOMAC-Gr), and the Timed Up and Go (TUG) and 9-stairs-ascend/descend (9S-A/D) tests. Known-groups validity was examined using TUG score (cut-off 13.5 s) as an estimate variable. Responsiveness was examined before and 4 weeks after direct anterior minimal invasive surgery. Results: Reliability: Internal consistency was moderate (Cronbach’s a = 0.614, p < 0.001). Test-retest reliability was excellent (ICC = 0.881, 95% CI, 0.824–0.920). Reproducibility: Floor and ceiling effects were both 1.1%; measurement error was 3.54 ( p < 0.05); minimal important change was lower than minimal detectable change. Validity: mHHS-Gr correlated strongly with both LEFS-Greek and WOMAC-Gr (Pearson’s r 0.801 and −0.783, respectively; p < 0.001). The questionnaire’s correlations with TUG and 9S-A/D were also significant but moderate (Spearman’s ρ: −0.547 and −0.575, respectively; p < 0.001). Known-groups validity showed that mHHS-Gr scores were significantly higher in participants with TUG < 13.5 seconds than in those with TUG > 13.5 seconds ( p < 0.001). In ROC analysis, the cut-off point of 52.5 yielded sensitivity 81% and specificity 71%. Responsiveness: Standardised response mean and Guyatt’s responsiveness statistic were greater than 0.8. Discussion: mHHS-Gr showed significant moderate to excellent reliability, significant moderate to strong validity properties and excellent responsiveness. Overall, mHHS-Gr could be a reliable and valid PRO measure for assessing patients with osteoarthritis of the hip.

PurposeThe Swedish National Diabetes Register (NDR) has developed a diabetes-specific questionnaire to collect information on individuals' management of their diabetes, collaboration with healthcare providers and the disease’s impact on daily life. Our main objective was to develop measures of well-being, abilities to manage diabetes and judgements of diabetes care, and to detect and quantify differences using the NDR questionnaire.Design, setting and participantsThe questionnaire was analysed with using responses from 3689 participants with type 1 and 2 diabetes, randomly sampled from the NDR population, combined with register data on patient characteristics and cardiovascular and diabetes complication risk factors.MethodsWe used item response theory to develop scales for measuring well-being, abilities to manage diabetes and judgements of diabetes care (scores). Test–retest reliability on the scale level was analysed with intraclass correlation. Associations between scores and risk factor levels were investigated with subgroup analyses and correlations.ResultsWe obtained scales with satisfactory measurement properties, covering patient reported outcome measures such as general well-being and being free of worries, and patient reported experience measure, for example, access and continuity in diabetes care. All scales had acceptable test–retest reliability and could detect differences between diabetes types, age, gender and treatment subgroups. In several aspects, for example, freedom of worries, type 1 patients report lower than type 2, and younger patients lower than older. Associations were found between some scores and glycated haemoglobin, but none with systolic blood pressure or low-density lipoprotein cholesterol. Clinicians report positive experience of using scores, visually presented, in the patient dialogue.ConclusionsThe questionnaire measures and detects differences in patient well-being, abilities and judgements of diabetes care, and identifies areas for improvement. To further improve diabetes care, we conclude that patient-reported measures are important supplements to cardiovascular and diabetes complication risk factors, reflecting patient experiences of living with diabetes and diabetes care.

ObjectivesWe developed a patient-reported outcome (PRO) instrument to assess the skin-related quality of life in patients with systemic sclerosis (SSc).MethodsParticipants with SSc provided input on skin-related health effects through focus groups. We developed items for scleroderma skin PRO (SSPRO) to encompass these effects. Further consideration from cognitive interviews and an expert panel led to reduction and modification of items. A 22-item SSPRO was field tested. Psychometric analysis included test–retest reliability, internal consistency and exploratory factor analysis (EFA). Construct validity was assessed through correlation with other participant and physician-assessed measures.Results140 participants completed the SSPRO: mean age was 53.4 years, median disease duration was 5 years, 82.1% were female and 32.9% had diffuse cutaneous SSc. EFA supported four factors in SSPRO corresponding to hypothesised constructs: physical effects, physical limitations, emotional effects and social effects. Removal of 4/22 items resulted in acceptable goodness-of-fit statistics. Test–retest reliability (intraclass correlation coefficient=0.61–0.83) was moderate to high and internal consistency (Cronbach's α=0.89–0.96) was high. SSPRO correlated strongly with other participant-reported measures (r=0.59–0.88) suggesting construct validity, and less well with physician-assessed measures (r=0.31–0.40). SSPRO scores were significantly different for each level of participant-reported skin severity, and for limited versus diffuse cutaneous SSc.ConclusionsSSPRO has been developed with extensive patient input and demonstrates evidence for reliability and validity. It is complementary to existing measures of SSc skin involvement with emphasis on the patient's experience. Further research is needed to assess its sensitivity to change.

OBJECTIVEThe 6-minute walking test (6WT) is used to determine restrictions in a subject’s 6-minute walking distance (6WD) due to lumbar degenerative disc disease. To facilitate simple and convenient patient self-measurement, a free and reliable smartphone app using Global Positioning System coordinates was previously designed. The authors aimed to determine normative values for app-based 6WD measurements.METHODSThe maximum 6WD was determined three times using app-based measurement in a sample of 330 volunteers without previous spine surgery or current spine-related disability, recruited at 8 centers in 5 countries (mean subject age 44.2 years, range 16–91 years; 48.5% male; mean BMI 24.6 kg/m2, range 16.3–40.2 kg/m2; 67.9% working; 14.2% smokers). Subjects provided basic demographic information, including comorbidities and patient-reported outcome measures (PROMs): visual analog scale (VAS) for both low-back and lower-extremity pain, Core Outcome Measures Index (COMI), Zurich Claudication Questionnaire (ZCQ), and subjective walking distance and duration. The authors determined the test-retest reliability across three measurements (intraclass correlation coefficient [ICC], standard error of measurement [SEM], and mean 6WD [95% CI]) stratified for age and sex, and content validity (linear regression coefficients) between 6WD and PROMs.RESULTSThe ICC for repeated app-based 6WD measurements was 0.89 (95% CI 0.87–0.91, p < 0.001) and the SEM was 34 meters. The overall mean 6WD was 585.9 meters (95% CI 574.7–597.0 meters), with significant differences across age categories (p < 0.001). The 6WD was on average about 32 meters less in females (570.5 vs 602.2 meters, p = 0.005). There were linear correlations between average 6WD and VAS back pain, VAS leg pain, COMI Back and COMI subscores of pain intensity and disability, ZCQ symptom severity, ZCQ physical function, and ZCQ pain and neuroischemic symptoms subscores, as well as with subjective walking distance and duration, indicating that subjects with higher pain, higher disability, and lower subjective walking capacity had significantly lower 6WD (all p < 0.001).CONCLUSIONSThis study provides normative data for app-based 6WD measurements in a multicenter sample from 8 institutions and 5 countries. These values can now be used as reference to compare 6WT results and quantify objective functional impairment in patients with degenerative diseases of the spine using z-scores. The authors found a good to excellent test-retest reliability of the 6WT app, a low area of uncertainty, and high content validity of the average 6WD with commonly used PROMs.

Test Retest Reliability

The Victorian Institute of Sport Assessment (VISA) questionnaire model is based on item response theory using a graded response (responses reflect increasing difficulty). The purpose of the VISA-G is to monitor patient outcomes and evaluate treatment strategies for people with greater trochanteric pain syndrome (GTPS). The primary aim of the current study was to translate and culturally adapt the VISA-G into a Danish context (DK) through forward and back translation and cognitive interviews. The second aim was to establish test–retest reliability and face validity of the VISA-G into a Danish context (DK). No major disagreements were observed between the original and translated versions of the questionnaire. A total of 58 heterogenous asymptomatic, and 49 symptomatic respondents (response rate: 92% and 78% respectively) completed the VISA-G.DK twice, 1 week apart. The VISA-G.DK had excellent internal consistency (Cronbach’s alpha: asymptomatic = 0.86; symptomatic = 0.98). The test–retest reliability was excellent for the total score: ICC: 0.961 (95% CI [0.933–0.978]). Standard Error Measurement was calculated to be 0.6. Bland–Altman plots showed no significant or relevant differences from test to retest in the total score with mean differences below 1 (0.61). The minimal detectable change was 3.17 for both groups. The VISA-G.DK was found to be valid, reliable and acceptable for use in the Danish population.
