The HAND-Q: Psychometrics of a New Patient-reported Outcome Measure for Clinical and Research Applications.

ABSTRACT: The perspective of the patient in measuring the outcome of their hand treatment is of key importance. We developed a hand-specific patient-reported outcome measure to provide a means to measure outcomes and experiences of care from the patient perspective, that is, HAND-Q.

Methods

Data were collected from people with a broad range of hand conditions in hand clinics in six countries between April 2018 and January 2021. Rasch measurement theory analysis was used to perform item reduction and to examine reliability and validity of each HAND-Q scale.

Results

A sample of 1277 patients was recruited. Participants ranged in age from 16 to 89 years, 54% were women, and a broad range of congenital and acquired hand conditions were represented. Rasch measurement theory analysis led to the refinement of 14 independently functioning scales that measure hand appearance, health-related quality of life, experience of care, and treatment outcome. Each scale evidenced reliability and validity. Examination of differential item functioning by age, gender, language, and type of hand condition (ie, nontraumatic versus traumatic) confirmed that a common scoring algorithm for each scale could be implemented.

Conclusions

The HAND-Q was developed following robust psychometric methods to provide a comprehensive modular independently functioning set of scales. HAND-Q scales can be used to assess and compare evidence-based outcomes in patients with any type of hand condition.

Project description:BackgroundPatient-reported outcome (PRO) measures developed and validated on patients with the currently defined phenotypes of chronic rhinosinusitis (CRS) are needed to support clinical trials in CRS.ObjectiveThis study developed and examined the initial reliability and validity of the CRS-PRO, a new PRO measure of CRS.MethodsInstrument development was performed through structured interviews and focus groups with clinical experts and 45 patients with CRS meeting current definitions of disease, 21 patients with CRS without nasal polyps (CRSsNP), and 24 patients with CRS with nasal polyps (CRSwNP) to identify items important to patients. Then another 50 patients (32 with CRSsNP and 18 with CRSwNP) with stable CRS symptoms were enrolled to evaluate the reliability of the instrument. Each patient completed the CRS-PRO, Sinonasal Outcome Test-22 (SNOT-22), and 4 Patient-Reported Outcome Measurement Information System short forms at the baseline visit and then at least 7 days later.ResultsAfter the development process, 21 items were identified from the conceptual domains of physical symptoms, sensory impairment, psychosocial effects, and life impact. Using the responses of the 50 patients with CRS, 21 draft items were further refined to 12 items by eliminating conceptually similar or highly correlated items or those with low mean symptom severity. The 12-item questionnaire was shown to have excellent internal consistency (Cronbach α, 0.86) and test-retest reliability with a high intraclass correlation coefficient (0.89) and Pearson's correlation (r = 0.82, P < .0001). The 12-item CRS-PRO correlated highly with the longer SNOT-22 (r = 0.83, P < .0001) demonstrating its concurrent validity. We also demonstrated validity and reliability in a separate analysis for patients with CRSsNP and CRSwNP.ConclusionThe CRS-PRO is a concise, valid, and reliable measure that was developed with extensive input from patients with CRS with current disease definitions.

Project description:IntroductionChronic Hand Eczema (CHE) is an inflammatory skin disease of the hands. The Hand Eczema Symptom Diary (HESD) is a new patient-reported outcome measure of worst severity of core CHE signs/symptoms. This study aimed to evaluate content and psychometric validity of the HESD.MethodsThe HESD was developed based on the literature and concept elicitation interviews. Qualitative cognitive debriefing interviews were conducted with CHE patients to assess relevance and understanding of items, response options and recall period. Psychometric properties of the HESD (item performance, dimensionality, reliability, validity, responsiveness and estimation of meaningful change thresholds) were then assessed, first using data from a phase 2b trial (NCT03683719), and confirmed using data from the first 280 participants completing the 16-week treatment phase of a phase 3 trial (NCT04871711).ResultsCognitive debriefing supported item refinement and removal of items and confirmed all items were well understood and relevant to patients. Item properties and dimensionality analyses in the phase 2b data supported removal of additional items, resulting in the 6-item HESD included in the phase 3 trial. Unidimensionality was supported by inter-item correlations (all > 0.70) and Rasch analysis. Internal consistency (Cronbach's alpha = 0.96) and test-retest reliability (Intraclass Correlation Coefficient > 0.89) results were very strong. Construct validity was supported by moderate correlations with concurrent measures (0.53-0.64) and significant differences between severity groups (p < 0.001). Large effect sizes for mean change scores in participants that improved and significant differences between change groups indicated the ability to detect change. Anchor-based analyses supported within-individual responder definitions of ≥ 4-points for improvements in 7-day average HESD scores.ConclusionThe HESD is the first CHE-specific, patient-reported outcome measure of CHE signs/symptoms developed and validated in line with regulatory guidance. This article provides evidence of strong content validity and psychometric validity and shows improvements of ≥ 4 points on 7-day average HESD scores represent clinically meaningful, important changes.Trial registrationNCT03683719, NCT04871711.
