Cross-Cultural Translation and Validation of the Spanish Version of the Patellofemoral Pain and Osteoarthritis Subscale of the KOOS (KOOS-PF)

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.

Test Retest Reliability

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.

Test Retest Reliability

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.

BACKGROUND: To date the Neck OutcOme Score (NOOS) was not cross-culturally adapted, validated or available in the Arabic language, although it was available in other languages. OBJECTIVE: To translate and cross-culturally adapt the Arabic version of the Neck OutcOme Score (NOOS-Ar) and study its psychometric properties. METHODS: A sample of 146 subjects with chronic neck pain filled in the NOOS-Ar questionnaire to determine the Cronbach’s alpha (α) for internal consistency, test-retest reliability by intraclass correlation coefficients(2,1) [ICC(2,1)], inter-item correlation, measurement error by coefficient of variance and minimal detectable change, ceiling and floor effects, convergent construct validity with visual analog scale (VAS) by Spearman’s rank correlation coefficient (ρ) and factor analysis to calculate and determine its psychometric properties. RESULTS: Excellent internal consistency (Cronbach’s α> 0.9) and test-retest reliability [ICC(2,1)> 0.9] were observed in NOOS-Ar. None of the five subscales of the NOOS-Ar showed a floor or ceiling effect. The coefficient of variance was generally high, but the minimal detectable change was within the acceptable range (< 30%). The ‘everyday activity and pain’ and ‘symptoms’ subscales of the NOOS-Ar, showed a moderate correlation with VAS. CONCLUSION: The NOOS-Ar is highly reliable and has a moderate to good degree of convergent construct validity with VAS with no floor or ceiling effects.

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.

Community Dwelling Older Adults

BackgroundPerceived ability or confidence plays an important role in determining function and behavior. The modified Gait Efficacy Scale (mGES) is a 10-item self-report measure used to assess walking confidence under challenging everyday circumstances.ObjectiveThe purpose of this study was to determine the reliability, internal consistency, and validity of the mGES as a measure of gait in older adults.DesignThis was a cross-sectional study.MethodsParticipants were 102 community-dwelling older adults (mean [±SD] age=78.6±6.1 years) who were independent in ambulation with or without an assistive device. Participants were assessed using the mGES and measures of confidence and fear, measures of function and disability, and performance-based measures of mobility. In a subsample (n=26), the mGES was administered twice within a 1-month period to establish test-retest reliability through the intraclass correlation coefficient (ICC [2,1]). The standard error of measure (SEM) was determined from the ICC and standard deviation. The Cronbach α value was calculated to determine internal consistency. To establish the validity of the mGES, the Spearman rank order correlation coefficient was used to examine the association with measures of confidence, fear, gait, and physical function and disability.ResultsThe mGES demonstrated test-retest reliability within the 1-month period (ICC=.93, 95% confidence interval=.85, .97). The SEM of the mGES was 5.23. The mGES was internally consistent across the 10 items (Cronbach α=.94). The mGES was related to measures of confidence and fear (r=.54–.88), function and disability (Late-Life Function and Disability Instrument, r=.32–.88), and performance-based mobility (r=.38–.64).LimitationsThis study examined only community-dwelling older adults. The results, therefore, should not be generalized to other patient populations.ConclusionThe mGES is a reliable and valid measure of confidence in walking among community-dwelling older adults.

Objective The purpose of this study is to introduce a standardised assessment tool by verifying the reliability of the translated Korean version of the Feeding Abilities Assessment (K-FAA), which was developed to suit Korean culture. Methods The research subjects were 65 patients with dementia living in nursing homes. The K-FAA was completed by verifying the suitability of translation and reverse translation. The validity of the K-FAA was established through content validity, while its reliability was analysed based on internal consistency reliability for the items, test–retest reliability and inter-rater reliability. Results The content validity index determined, based on the assessment of professors, occupational therapists, and nurses, was more than .70. Cronbach’s α was more than .929, showing good internal consistency. A test–retest reliability of .884 was derived using Pearson’s correlation coefficient (p < .01), and an inter-rater reliability of .800 was derived using the kappa coefficients; intraclass correlation coefficient was .897, which also indicated good reliability. Conclusion The K-FAA was modified to fit the Korean domestic situation, and this assessment had high reliability. Therefore, K-FAA can evaluate the feeding ability of patients with dementia. Future studies should focus on providing evidence-based data to maintain or supplement the feeding ability of patients with dementia in Korea.

BackgroundPatellofemoral pain and osteoarthritis are prevalent and associated with substantial pain and functional impairments. Patient-reported outcome measures (PROMs) are recommended for research and clinical use, but no PROMs are specific for patellofemoral osteoarthritis, and existing PROMs for patellofemoral pain have methodological limitations. This study aimed to develop a new subscale of the Knee injury and Osteoarthritis Outcome Score for patellofemoral pain and osteoarthritis (KOOS-PF), and evaluate its measurement properties.MethodsItems were generated using input from 50 patients with patellofemoral pain and/or osteoarthritis and 14 health and medical clinicians. Item reduction was performed using data from patellofemoral cohorts (n=138). We used the COnsesus-based Standards for the selection of health Measurements INstruments guidelines to evaluate reliability, validity, responsiveness and interpretability of the final version of KOOS-PF and other KOOS subscales.ResultsFrom an initial 80 generated items, the final subscale included 11 items. KOOS-PF items loaded predominantly on one factor, pain during activities that load the patellofemoral joint. KOOS-PF had good internal consistency (Cronbach’s α 0.86) and adequate test–retest reliability (intraclass correlation coefficient 0.86). Hypothesis testing supported convergent, divergent and known-groups validity. Responsiveness was confirmed, with KOOS-PF demonstrating a moderate correlation with Global Rating of Change scores (r 0.52) and large effect size (Cohen’s d 0.89). Minimal detectable change was 2.3 (groups) and 16 (individuals), while minimal important change was 16.4. There were no floor or ceiling effects.ConclusionsThe 11-item KOOS-PF, developed in consultation with patients and clinicians, demonstrated adequate measurement properties, and is recommended for clinical and research use in patients with patellofemoral pain and osteoarthritis.

Test Retest Reliability

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.

Test Retest Reliability

INTRODUCTION: The Patient-Rated Wrist Hand Evaluation (PRWHE) is a widely used measure of patient[1]reported disability, pain and appearance related to both hand and wrist disorders. It has been adapted cross[1]culturally worldwide but not in Malaysia. We performed a translation and cross-cultural adaptation of the PRWHE into a Malay version (PRWHE-MV) with assessed reliability and validity in patients presented with hand and/or wrist disorders. MATERIAL AND METHODS: PRWHE-MV was developed via translation and resolution of cultural discrepancies. A total of 83 patients (38 men, 45 women) with the mean age of 38 (SD 14) years and hand and/or wrist disorders completed both PRWHE-MV and the Malay version of Quick DASH during their first orthopaedic hand clinic follow up, and a second PRWHE-MV at 48 hours later. Intraclass Correlation Coefficient (ICC) was used to assess test-retest reliability of the PRWHE-MV while Cronbach’s alpha was calculated to assess the internal consistency. We tested the validity of PRWHE-MV against the Malay version of Quick DASH by calculating the nonparametric Spearman’s correlation coefficient between these two measures. RESULTS: There was no major cultural problems during the forward and backward translation of PRWHE, except for a minor change owing to cultural discrepancy in toilet hygiene. The Cronbach alpha PRWHE-MV was 0.978 (SEM = 5.5) at baseline and 0.979 (SEM = 5.35) at the second assessment. For the test-retest reliability, ICC was 0.99. There was a strong direct correlation between the scores for the PRWHE-MV and the Quick DASH (r = 0.916, p< 0.001). A majority of patients considered hand appearance somewhat important and were bothered in the past week. Their main concerns were gaining back normal hand function and subsequently returning to work. CONCLUSION: The PRWHE-MV showed high internal consistency, test-retest reliability and good validity in patients with hand and/or wrist disorders.
