Context  Clinicians are urged to document patient-based outcomes during rehabilitation to measure health-related quality of life (HRQOL) from the patient's perspective. It is unclear how scores on patient-reported outcome instruments (PROs) vary over the course of an athletic season because of normal athletic participation. Objective  Our primary purpose was to evaluate the effect of administration time point on HRQOL during an athletic season. Secondary purposes were to determine test-retest reliability and minimal detectable change scores of 3 PROs commonly used in clinical practice and if a relationship exists between generic and region-specific outcome instruments. Design  Cross-sectional study. Setting  Athletic facility. Patients or Other Participants  Twenty-three collegiate soccer athletes (11 men, 12 women). Main Outcome Measure(s)  At 5 time points over a spring season, we administered the Disablement in the Physically Active Scale (DPA), Foot and Ankle Ability Measure-Sport, and Knee Injury and Osteoarthritis Outcome Score (KOOS). Results  Time effects were observed for the DPA (P = .011) and KOOS Quality of Life subscale (P = .027). However, the differences between individual time points did not surpass the minimal detectable change for the DPA, and no post hoc analyses were significant for the KOOS-Quality of Life subscale. Test-retest reliability was moderate for the KOOS-Pain subscale (intraclass correlation coefficient = 0.71) and good for the remaining KOOS subscales, DPA, and Foot and Ankle Ability Measure-Sport (intraclass correlation coefficients > 0.79). The DPA and KOOS-Sport subscale demonstrated a significant moderate relationship (P = .018). Conclusions  Athletic participation during a nontraditional, spring soccer season did not affect HRQOL. All 3 PROs were reliable and could be used clinically to monitor changes in health status throughout an athletic season. Our results demonstrate that significant deviations in scores were related to factors other than participation, such as injury. Finally, both generic and region-specific instruments should be used in clinical practice.

Abstract Objective The aim of this study was to translate to Spanish the patellofemoral pain and osteoarthritis subscale of the knee injury and osteoarthritis outcome score (KOOS-PF) and validate this Spanish version of a disease-specific patient-reported outcome measure (PROM) for patellofemoral pain. Results The KOOS-PF was translated to Spanish and sixty patients with patellofemoral pain and/or osteoarthritis accepted to complete the questionnaire. 1-week later 58 patients answered the questions again for the test–retest reliability validation and finally 55 patients completed 1-month later for the responsiveness assessment. The Spanish version showed very good internal consistency (Cronbach’s alpha: 0.93) and test–retest reliability (intraclass correlation coefficient: 0.82). Responsiveness was confirmed, showing a strong correlation with the global rating of change (GROC) score (r 0.64). The minimal detectable change was 11.1 points, the minimal important change was 17.2 points, and there were no floor or ceiling effects for the score.

Abstract Objective The mini-BESTest is a balance measure for assessment of the underlying physiological systems for balance control in adults. Evaluations of test–retest reliability of the mini-BESTest in larger samples of people with multiple sclerosis (MS) are lacking. The purpose of this study was to investigate test–retest reliability of the mini-BESTest total and section sum scores and individual items in people with mild to moderate overall MS disability. Methods This study used a test–retest design in a movement laboratory setting. Fifty-four people with mild to moderate overall MS disability according to the Expanded Disability Status scale (EDSS) were included, with 28 in the mild subgroup (EDSS 2.0–3.5) and 26 in the moderate subgroup (EDSS 4.0–5.5). Test–retest reliability of the mini-BESTest was evaluated by repeated measurements taken 1 week apart. Reliability and measurement error were analyzed. Results Test–retest reliability for the total scores were considered good to excellent, with intraclass correlation coefficients of .88 for the whole sample, .83 for the mild MS subgroup, and .80 for the moderate MS subgroup. Measurement errors were small, with standard error of measurement and minimal detectable change of 1.3 and 3.5, respectively, in mild MS, and 1.7 and 4.7, respectively, in moderate MS. The limits of agreement were − 3.4 and 4.6. Test–retest reliability for the section scores were fair to good or excellent; weighted kappa values ranged from .62 to .83. All items but 1 showed fair to good or excellent test–retest reliability, and percentage agreement ranged from 61% to 100%. Conclusions The mini-BESTest demonstrated good to excellent test–retest reliability and small measurement errors and is recommended for use in people with mild to moderate MS. Impact Knowledge of limits of agreement and minimal detectable change contribute to interpretability of the mini-BESTest total score. The findings of this study enhance the clinical usefulness of the test for evaluation of balance control and for designing individually customized balance training with high precision and accuracy in people with MS.

Abstract Introduction Static postural stability is the ability to maintain the posture with minimum sway. Increasing postural sway during standing in different sensory conditions is associated with aging due to decline in sensory and motor functions. Sway area measured by using sway meter is usually simple method for assessing postural stability in elderly subjects. Like many biological measurements, sway area has an intrinsic variability that affects their test-retest reliability and responsiveness of postural stability assessment. The minimal detectable change (MDC) is ability to detect smallest change beyond measurement error that reflects a reliable change. Therefore, the MDC value could provide information of clinical relevance on postural stability. The aims of this study were to determine test-retest reliability and MDC of sway area obtained from sway meter in elderly subjects. Methods Twelve healthy elderly subjects aged 60 years and above were participated in this study. The test and retest repeatability of postural sway measurements were performed twice with a 1-hour interval. For each subject was assess postural sway using Lord’s sway meter during standing on 4 sensory conditions for 30 seconds of each condition. The test-retest reliability of sway area was calculated using intraclass correlation coefficient. The MDC for each sway area was calculated to quantify clinical relevance. Results The test-retest reliability of sway area revealed good to excellent reliability ranged from 0.85 to 0.94. Standard error of measurement (SEM) and MDC ranged from 75 to 205 mm2 and 209 to 568 mm2, respectively. Discussion and Conclusion Our findings reveal that sway area in different sensory conditions could be used in assessment of postural stability in elderly subjects. SEM and MDC of sway area increased when subjects were asked to close their eyes and on foam surface. The sway meter is a reliable tool for assessing postural stability in clinical setting.

Abstract Background The Angioedema Quality of Life (AE-QoL) is the first patient reported outcome measure developed for the assessment of quality of life (QoL) impairment in patients with recurrent angioedema (RAE). This study aimed to evaluate the clinimetric properties of the AE-QoL in Thai patients and to establish categories of QoL impairment assessed by the AE-QoL. Methods The validated Thai version of the Dermatology Life Quality Index (DLQI) and Patient Global Assessment of Quality of Life (PGA-QoL) were used to comparatively evaluate the Thai version of AE-QoL. Spearman correlations between the Thai AE-QoL and two other standard measurements (DLQI and PGA-QoL) were investigated to determine convergent validity. The Thai DLQI and PGA-QoL were used to categorize patients according to their QoL. Known-group validity of the Thai AE-QoL was later analyzed. The reliability of the Thai AE-QoL was investigated using Cronbach’s alpha and intraclass correlation. Three different approaches including the distribution method, receiver operating characteristic curve analysis, and the anchor based-method were used for the interpretability. Results A total of 86 patients with RAE with a median age of 38.0 ± 15.1 years (range 18–76) were enrolled. Of those, 76 patients (88%) had RAE with concomitant wheals, and 10 patients (11.6%) had RAE only. The AE-QoL assessed RAE-mediated QoL impairment with high convergent validity and known-groups validity, high internal consistency and test-retest reliability, and good sensitivity to change. Although the AE-QoL did not differentiate between patients with moderate and large effect as measured by PGA-QoL or DLQI in this study, AE-QoL total values of 0–23, 24 to 38, and ≥ 39 could define patients with “no effect”, “small effect”, and “moderate to large effect” of RAE on their QoL, respectively. Conclusions This study supports the validity and reliability of the Thai version of the AE-QoL, which is a very different language from the original version. Categories allow to classify the effect of RAE on patients’ QoL as “none”, “small”, and “moderate to large”. Further studies are needed to confirm the applicability of AE-QoL in other Asian populations”.

BACKGROUND: The reliability of the evaluation of the Balance Evaluation Systems Test (BESTest) and its two abbreviated versions are confirmed for balance characteristics and reliability. However, they are not utilized in cases of spinocerebellar ataxia (SCA). OBJECTIVE: We aimed to examine the test-retest reliability and minimal detectable change (MDC) of the BESTest and its abbreviated versions in persons with mild to moderate spinocerebellar ataxia. METHODS: The BESTest was performed in 20 persons with SCA at baseline and one month later. The scores of the abbreviated version of the BESTest were determined from the BESTest scores. The interclass correlation coefficient (1,1) was used as a measure of relative reliability. Furthermore, we calculated the MDC in the BESTest and its abbreviated versions. RESULTS: The intraclass correlation coefficients (1,1) and MDC at 95% confidence intervals were 0.92, 8.7(8.1%), 0.91, 4.1(14.5%), and 0.81, 5.2(21.6%) for the Balance, Mini-Balance, and Brief-Balance Evaluation Systems Tests, respectively. CONCLUSIONS: The BESTest and its abbreviated versions had high test-retest reliability. The MDC values of the BESTest could enable clinicians and researchers to interpret changes in the balance of patients with SCA more precisely.

18527 Background: ZEST is a placebo-controlled trial of sertraline for people with advanced cancer who feel depressed, anxious or tired but do not have a clear indication for antidepressants. We describe here the aspects of quality of life (QL) rated most troublesome at baseline by the first 150 subjects. Methods: Subjects completed a battery of QL questionnaires including the CES-D, HADS, FACT-G, FACT-Fatigue, and the Patient Disease and Treatment Assessment Form (Pt DATA Form). The Pt DATA Form assesses pertinent symptoms and concerns using 40 single items with a uniform response scale from 0 (no trouble at all) to 10 (worst I can imagine). Test-retest reliability was assessed with the intraclass correlation coefficient (ICC). Convergent validity was assessed by testing correlations between single items from the PT DATA Form and the corresponding, validated, multi-item scales. Results: The median age was 66 (IQR 59 to 73); median Karnofsky Perfomance Status was 80 (IQR 70 to 90); 63% were male; commonest primaries were colorectal (17%), lung (16%), prostate, (14%), breast (13%), and gynaecologic (10%). The aspects rated worst (mean score, proportion scoring >3) were: Fatigue (5.5, 90%), Problems with sex (4.1, 51%), Trouble sleeping (3.6, 49%), Drowsiness (3.5, 54%), Not feeling myself (3.5, 51%), Pain (3.4, 45%), Shortness of breath (3.4, 47%), Problems doing what I wanted (3.1, 45%), Anxiety (3.0, 40%), Depression (2.7, 36%), Dry mouth (2.7, 38%), Trouble concentrating (2.7, 30%), Irritability (2.6, 32%), Altered sense of taste (2.5, 34%), Difficulty walking (2.4, 32%), and Constipation (2.1, 24%). Mean scores were higher in men than women for Problems with sex (5.0 v 2.4, p < 0.001); and, in subjects aged 65 or younger for Hair loss (2.4 v 1.1, p = .01). There were no other significant differences by gender or age. Correlations supported the validity of the single item scales for depression, anxiety, fatigue; and for physical, emotional and overall well-being. The test-retest reliability of the Pt DATA Form was good (ICC >0.5 for 34 of 40 items). Conclusions: Pertinent aspects of QL were validly measured with single item scales. Insomnia, dry mouth, altered sense of taste and irritability were more troublesome than many other, better studied symptoms. No significant financial relationships to disclose.

Objective.There is currently no universally accepted measure of quality of life in ankylosing spondylitis (AS). Our objective was to develop and evaluate a patient-reported outcome measure of quality of life in AS, EASi-QoL.Methods.We used patient interviews, a literature review, and completion of an individualized measure of AS quality of life during clinic-based and pilot surveys to derive questionnaire content. Classical and modern psychometrics were then used to evaluate the questionnaire using data from a large UK-based postal survey of 1000 patients with AS.Results.Data analysis from the interviews and clinic-based and postal surveys produced a 57-item self-completed questionnaire. Fifteen items were removed as a result of patient interviews and the pilot survey. In total, 612 (64.0%) patients responded to the main postal survey. After assessment of data quality, confirmatory factor analysis, and Rasch analysis, 20 items were found to contribute to 4 domains of AS-related quality of life: physical function, disease activity, emotional well-being, and social participation. Item-total correlations ranged from 0.66 to 0.84. Cronbach’s alpha and test-retest reliability estimates were 0.88–0.92 and 0.88–0.93, respectively. Confirmed hypothesized correlations with the AS Quality of Life questionnaire, the Bath AS Disease Activity Index, Bath AS Functional Index, SF-36, EQ-5D, and the Hospital Anxiety and Depression Scale were evidence for the construct validity of the EASi-QoL.Conclusion.The EASi-QoL has good evidence of data quality, internal reliability, test-retest reliability, and content and construct validity, and should be considered for use with patients in routine practice settings and in evaluative studies including clinical trials. Measurement responsiveness and minimal important change are currently being assessed.

Abstract Background: Patellofemoral pain is a very common complaint in orthopedic sports medicine clinics. Disease-specific patient-reported outcome measures (PROMs) are useful for research and clinical practice; thus, it is important to have validated translations available for new PROMs. This study aims to translate and validate the Spanish version of the patellofemoral pain and osteoarthritis subscale of the knee injury and osteoarthritis outcome score (KOOS-PF).Methods: The KOOS-PF was translated and culturally adapted to Spanish following current guidelines, which included translation, back-translation, conciliation and pilot studies. Patients with a diagnosis of patellofemoral pain and/or osteoarthritis from one medical center were invited to participate and complete the questionnaire. The evaluation of the score included internal consistency (Cronbach´s alpha), floor and ceiling effects, measurement error, minimal detectable change and minimal important change. For test-retest reliability, the intraclass correlation coefficient (ICC) was used, and for responsiveness, the global rating of change (GROC) scale was measured one month later.Results: Sixty patients with patellofemoral pain and/or osteoarthritis were included in the study. The Spanish version showed very good internal consistency (Cronbach’s alpha: 0.93) and test-retest reliability (intraclass correlation coefficient: 0.82). Responsiveness was confirmed, with the KOOS-PF demonstrating a strong correlation with the GROC score (r 0.64). The minimal detectable change was 11.1 points, the minimal important change was 17.2 points, and there were no floor or ceiling effects for the score.Conclusions: The Spanish version of the KOOS-PF demonstrated very good measurement properties, including internal consistency, reliability and responsiveness. The KOOS-PF can be used in Spanish-speaking patients for clinical and research purposes in patellofemoral pain and osteoarthritis.Trial registration: Fundación Valle del Lili, Biomedical Research Ethical Committee: No. 01438.

The clinical assessment of sport-related lower extremity injuries plays important role in diagnosis and therapeutic strategies as well as return to activity. The Foot and Ankle Ability Measure (FAAM) is a valid and reliable self-reported outcome instrument used to detect foot and ankle disorders. The purpose of this study is to translate, cross-culturally adapt and validate the FAAM questionnaire for use in Turkish-speaking athletes who have foot and ankle disorders. Fifty-one basketball, soccer and volleyball athletes volunteered to participate. Test–retest reliability analyses revealed good and excellent reliability (intraclass correlation coefficient (ICC) = 0.83–0.92). Concurrent validity was tested between the FAAM-T subscores and both the visual analog scale for pain/activity limitations and functional performance tests, yielding moderate to high correlations (r = −0.522 to −0.869, p < .05). The results of this study showed that the FAAM-T is a reliable and valid questionnaire for self-reported assessment of pain and disability in athletes suffering from foot and ankle disorders.

Abstract Background: Individuals with multiple sclerosis (MS) have balance deficits that result in falls. Balance tests developed for older adults do not discriminate between fallers and nonfallers with MS. The Balance Evaluation Systems Test (BESTest) identifies body systems contributing to imbalance/fall risk. This study evaluated the test-retest reliability and construct validity of the BESTest to assess balance in individuals with MS, compared the diagnostic accuracy of the BESTest and Berg Balance Scale (BBS), and investigated the minimal detectable change of the BESTest in this population. Methods: Twenty individuals with MS were recruited. Age, onset of disease, and fall history were obtained. The following measures were used: Expanded Disability Status Scale, University of Illinois at Chicago Fear of Falling Measure, BESTest, and BBS. Twelve participants were retested to determine test-retest reliability of the BESTest. Results: The BESTest demonstrated strong test-retest reliability (intraclass correlation coefficient [3,1] = 0.98 [95% CI, 0.91–0.99], P = .01) and was highly correlated with the BBS (r = 0.94, P = .01). The BBS had poor accuracy to identify fallers. Using a score of 81%, the BESTest had moderate sensitivity (0.89) to identify fallers. The standard error of the measurement for the BESTest was 4.16 points, which translates into a minimal detectable change of 9.7% [90% CI] to 11.5% [95% CI]. Conclusions: The BESTest demonstrates excellent test-retest reliability and diagnostic utility as a measure of functional balance in persons with moderate MS. A change in BESTest score of at least 10% may indicate a true change in balance performance in this population.
