Abstract
Background Lower extremity trauma can have a significant impact on a patient's quality of life. The LIMB-Q is a recently developed and validated patient-reported outcome measure that assesses patient-specific outcomes and experience of health care. The aim of this study was to translate and linguistically validate the LIMB-Q from English to German. Methods The translation was performed by combining World Health Organization and Professional Society for Health Economics and Outcomes Research guidelines. The process consisted of forward translations, a backward translation, expert panel meetings, cognitive debriefing interviews with patients, and several rounds of discussion and reconciliation with the creators of LIMB-Q. The goal was to obtain a culturally and conceptually accurate translation of LIMB-Q into German for use in Switzerland. Results From the two forward translations, there was one primary discrepancy between the two translators that was discussed to determine the most conceptually accurate translation. From the backward translations, there were 63 items that required discussion and re-translation. Nine patients participated in the cognitive debriefing interviews, which led to three items being modified. The translation process led to a linguistically validated and conceptually equivalent German version of the LIMB-Q. Conclusions The German (Switzerland) version of LIMB-Q is now available. This will offer a valuable tool for lower extremity trauma research and clinical care in German-speaking populations.

Abstract
The objective of this study was to translate the Preference-Based Amyotrophic Lateral Sclerosis Scale to French-Canadian. After the scale underwent forward and back translations, the expert committee examined the translated versions and found minor grammatical errors and suggested idioms to be changed to better represent French-Canadian language. Cognitive debriefing interviews were carried out to assess the pre-final version for clarity, and minor changes were made. Consensus from the expert committee and people with amyotrophic lateral sclerosis on the measure's clarity, word choice, and meaning were achieved, resulting in the final French version of the Preference-Based Amyotrophic Lateral Sclerosis Scale.

Abstract
PURPOSE In research people are often asked to fill out questionnaires about their health and functioning and some of the questions refer to serious health concerns. Typically, these concerns are not identified until the statistician analyses the data. An alternative is to use an individualized measure, the Patient Generated Index (PGI) where people are asked to self-nominate areas of concern which can then be dealt with in real-time. This study estimates the extent to which self-nominated areas of concern related to mood, anxiety and cognition predict the presence or occurrence of brain health outcomes such as depression, anxiety, psychological distress, or cognitive impairment among people aging with HIV at study entry and for successive assessments over 27 months. METHODS The data comes from participants enrolled in the Positive Brain Health Now (+ BHN) cohort (n = 856). We analyzed the self-nominated areas that participants wrote on the PGI and classified them into seven sentiment groups according to the type of sentiment expressed: emotional, interpersonal, anxiety, depressogenic, somatic, cognitive and positive sentiments. Tokenization was used to convert qualitative data into quantifiable tokens. A longitudinal design was used to link these sentiment groups to the presence or emergence of brain health outcomes as assessed using standardized measures of these constructs: the Hospital Anxiety and Depression Scale (HADS), the Mental Health Index (MHI) of the RAND-36, the Communicating Cognitive Concerns Questionnaire (C3Q) and the Brief Cognitive Ability Measure (B-CAM). Logistic regressions were used to estimate the goodness of fit of each model using the c-statistic. RESULTS Emotional sentiments predicted all of the brain health outcomes at all visits with adjusted odds ratios (OR) ranging from 1.61 to 2.00 and c-statistics > 0.73 (good to excellent prediction). Nominating an anxiety sentiment was specific to predicting anxiety and psychological distress (OR 1.65 & 1.52); nominating a cognitive concern was specific to predicting self-reported cognitive ability (OR 4.78). Positive sentiments were predictive of good cognitive function (OR 0.36) and protective of depressive symptoms (OR 0.55). CONCLUSIONS This study indicates the value of using this semi-qualitative approach as an early-warning system in predicting brain health outcomes.

Abstract
OBJECTIVE The self-administered version of the Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised (ALSFRS-R) is used to monitor function and disease progression in individuals with amyotrophic lateral sclerosis (ALS). However, the performance of the self-administered ALSFRS-R has not been assessed using Rasch Measurement Theory. Therefore, the purpose of this study was to examine the psychometric properties of the self-administered ALSFRS-R using Rasch analysis. METHODS Rasch analysis was performed on self-administered ALSFRS-R data from individuals with ALS across Canada. The following 6 aspects of Rasch analysis were examined using RUMM2030: fit via residuals and chi-square statistics, targeting via person-item threshold maps, dependency via item residual correlations, unidimensionality through principal components analysis of residuals, reliability via person separation index, and stability through differential item functioning analyses for sex, age, and language. RESULTS Analysis was performed on 122 participants (mean age: 52.9 years; 62.8% men). The overall scale demonstrated good fit, reliability, and stability; however, multidimensionality was found. To address this issue, items were divided into 3 subscales (bulbar, motor, and respiratory function), and Rasch analysis was performed for each subscale. The subscales demonstrated good fit, reliability, stability, and unidimensionality. However, there were still issues with item dependency for all subscale and targeting for bulbar and respiratory subscales. CONCLUSIONS The self-administered ALSFRS-R is reliable, internally valid, and stable across sex, age, and language subgroups; however, it is recommended that the ALSFRS-R be scored by subscale. Future studies can look at revising and/or adding items to tackle misfit, redundancy, and ceiling effects. IMPACT Self-administered measures are simple to administer and inexpensive. The self-administered ALSFRS-R was found to be psychometrically sound and can be used as a tool to monitor disease progression and function in ALS.

Abstract
PURPOSE Amyotrophic lateral sclerosis (ALS) is the most common motor neuron disease in adults. There are many patient-reported outcome measures (PROMs) for measuring quality of life (QoL) and health-related QoL (HRQoL) within this population; however, there is limited consensus regarding which are most valid, reliable, responsive, and interpretable. This systematic review assesses the psychometric properties and interpretability of QoL and HRQoL PROMs for individuals with ALS. METHODS This review was conducted following the Consensus-based Standards for the selection of health Measurement Instruments (COSMIN) methodology for systematic reviews of PROMs. MEDLINE, EMBASE, and CINAHL databases were searched. Studies were included if their aim was to evaluate one or more psychometric properties or the interpretability of QoL or HRQoL PROMs in individuals with ALS. RESULTS We screened 2713 abstracts, reviewed 60 full-text articles, and included 37 articles. Fifteen PROMs were evaluated including generic HRQoL (e.g., SF-36), ALS-specific HRQoL (e.g., ALSAQ-40), and individualized QoL (e.g., SEIQoL) measures. Evidence for internal consistency and test-retest reliability were acceptable. For convergent validity, 84% of hypotheses were met. For known-groups validity, outcomes were able to distinguish between healthy cohorts and other conditions. Responsiveness results ranged from low to high correlations with other measures over 3-24 months. Evidence for content validity, structural validity, measurement error, and divergent validity was limited. CONCLUSION This review identified evidence in support of the ALSAQ-40 or ALSAQ-5 for individuals with ALS. These findings can guide healthcare practitioners when selecting evidence-based QoL and HRQoL PROMs for patients and provide researchers with insight into gaps in the literature.

Abstract
ZusammenfassungDie systematische Erfassung des klinischen Zustands sowie der Erfahrung mit
Behandlung oder Versorgung durch einen strukturierten Bericht des Patienten wird
als „Patient-reported Outcome Measures“ (PROM) bezeichnet. Bei
der Amyotrophen Lateralsklerose (ALS) haben sich PROM insbesondere zur
Dokumentation funktioneller Defizite, z. B. mit der ALS-Funktionsskala,
und weiterer komplexer Symptome im Rahmen von klinischer Forschung etabliert. In
der Behandlungspraxis werden PROM dazu genutzt, den Verlauf und die Prognose der
Erkrankung einzuschätzen. Mit PROM werden neue biologische Biomarker
(z. B. Neurofilamente) und digitale Biomarker (z. B. durch den
Einsatz von Sensorik) auf ihre patientenzentrierte Relevanz evaluiert. Durch die
digitale Anwendung von PROM und die Verknüpfung mit digitalen Biomarkern
kann eine engmaschigere Erhebung von zu Hause aus erfolgen und damit die
Datenqualität erhöht werden. Patienten können selbst den
Gesundheitszustand monitorieren sowie Behandlungs- und Versorgungsergebnisse
dokumentieren. Damit nehmen sie zunehmend eine aktive Rolle in der individuellen
Behandlung und Versorgung ein.

Abstract
BACKGROUND The ALS Functional Rating Scale in its revised version (ALSFRS-R) is a disease-specific severity score that reflects motor impairment and functional deterioration in people with amyotrophic lateral sclerosis (ALS). It has been widely applied in both clinical practice and ALS research. However, in Germany, several variants of the scale, each differing slightly from the others, have developed over time and are currently in circulation. This lack of uniformity potentially hampers data interpretation and may decrease item validity. Furthermore, shortcomings within the standard ALSFRS-R questions and answer options can limit the quality and conclusiveness of collected data. METHODS In a multistage consensus-building process, 18 clinical ALS experts from the German ALS/MND network analyzed the ALSFRS-R in its current form and created an adapted, annotated, and revised scale that closely adheres to the well-established standardized English version. RESULTS Ten German-language variants of the ALSFRS-R were collected, three of which contained instructions for self-assessment. All of these variants were compiled and a comprehensive linguistic revision was undertaken. A short introduction was added to the resulting scale, comprising general instructions for use and explanations for each of the five reply options per item. This adapted version of the scale, named ALSFRS-R-SE (with the "SE" referring to "self-explanatory"), was carefully reviewed for language and comprehensibility, in both German and English. CONCLUSION An adapted and annotated version of the ALSFRS-R scale was developed through a multistage consensus process. The decision to include brief explanations of specific scale items and reply options was intended to facilitate ALSFRS-R-SE assessments by both healthcare professionals and patients. Further studies are required to investigate the accuracy and utility of the ALSFRS-R-SE in controlled trials and clinical real-world settings.

Abstract
Objective: The aim of this study was to refine the items of a preference-based amyotrophic lateral sclerosis health-related quality of life scale (PB-ALS HRQL scale) based on domains generated in a previous study. Methods: Survey methodology was used to assess item importance rating (IR) and independence. Median importance was calculated for each item and a rating of "very important" was required for the item to remain. Correlations were used to examine item independence. Highly correlated items (rs > 0.7) were considered for removal. Cognitive debriefing (CD) interviews, conducted by Zoom, telephone, or email based on participant preference and communication needs, were used to identify potential issues. Participants provided feedback about wording, clarity, response options, and recall period on randomly selected items. Items were considered finalized when three sequential CD participants approved the item with no revisions. Results: Thirty-four people with ALS (PALS, n = 16 females; age range 44-78 years; ALS Functional Rating Scale-Revised [ALSFRS-R] range 0-48) in Canada completed the survey; a subset of 18 PALS completed CD interviews (n = 8 female; age range 44-71 years; ALSFRS-R range 0-48). Four items were highly correlated with one or more items, were not rated as very important, or were not approved via CD and were removed. Conclusions: The final four-response option PB-ALS Scale includes eight items: recreation and leisure, mobility, interpersonal interactions and relationships, eating and swallowing, handling objects, communicating, routine activities, and mood. The next step is to translate the PB-ALS Scale into French and develop a scoring algorithm based on PALS' preferences.
