Cross-cultural adaptation, and Factor Structure of the Decision Styles Scale for Brazil

Introduction. This study aimed to validate the Hong Kong version of the Knee Injury and Osteoarthritis Outcome Score (HK-KOOS) for patients with knee osteoarthritis. Methods. Content validity was assessed using the Item and Scale Content Validity Index (I-CVI and S-CVI). Test-retest reliability and internal consistency were assessed by the Intraclass Correlation Coefficient (ICC) and Cronbach’s alpha. Dimensionality was assessed by performing exploratory factor analysis (EFA). Convergent and Divergent Validity was performed by examining the correlation between the HK-KOOS and the Chinese version of the Short Form 12 (SF-12) Health Survey, the Chinese Modified Barthel Index (C-MBI), and the Visual Analogue Scale for Pain (VAS-Pain). Ceiling and floor effects were also examined. Results. A total of 125 participants were recruited in this study. In general, all instructions, items, and response options were considered as understandable, indicating a satisfactory cross-cultural adaptation. The I-CVI and S-CVI scores were 0.80-1 and 0.90-1, respectively, indicating excellent content validity in terms of relevance, representativeness, and understandability. The test-retest reliability of all HK-KOOS subscales was satisfactory with ICC exceeding 0.70 for all domains. Cronbach’s alpha exceeded 0.80 for all subscales, indicating satisfactory internal consistency. Medium to strong correlations were found between the HK-KOOS and the VAS-Pain, SF-12, and C-MBI. However, factor analysis indicated a seven-factor structure, rather than the original five-factor structure. Items on pain and activities of daily living were loaded in the same factors. A floor effect was present in the sports and recreation subscale. Discussion and Conclusions. Future studies should further examine the dimensionality of the KOOS. The HK-KOOS is a culturally adapted, reliable, and valid outcome measure instrument to be used in Hong Kong patients with primary knee osteoarthritis.

Background: Diabetic foot care management is directed at patients with a history of complications, especially those with rising levels of hemoglobin A1c, and those who have had diabetes for several years. The aim of this study was to cross-culturally adapt a French-language version of the Diabetic Foot Self-care Questionnaire of the University of Malaga (DFSQ-UMA) for use in France. Methods: Cross-cultural adaptation was performed according to relevant international guidelines (International Society for Pharmacoeconomics and Outcomes Research), and the factor structure was determined. Internal consistency was measured using the Cronbach α. Item-total and inter-item correlations were assessed. Results: The French data set comprised 146 patients. The mean ± SD patient age was 62.60 ± 15.47 years. There were 47 women and 99 men. The structure matrix (with three factors) was tested by confirmatory factor analysis. The 16-item questionnaire had a Cronbach α of 0.92. The mean value for inter-item correlations was 0.48 (range, 0.17–0.86). The rotated solution revealed a three-factor structure that accounted for 48.10% of the variance observed. A significant inverse correlation was observed between questionnaire scores and hemoglobin A1c levels (r = –0.17; P < .01). Conclusions: This study validates the French-language version of the DFSQ-UMA, which can be used as a self-reported outcome measure for French-speaking patients in France.

Abstract Background: Patient reported outcome measures (PROMs) are recommended to enable the standardization of collected data and provide accurate representation of the patients’ subjective opinions of their functional capabilities. The purpose of this study was to perform linguistic and cross-cultural adaptation to establish a Polish version of the Lower Limb Functional Index (LLFI), and to evaluate the psychometric properties of internal consistency, reliability, error score, validity, and factor structure with standardized criteria PROMs in a population with lower limb problems. Methods: Linguistic and cultural adaptation complied with the International Society for Pharmacoeconomics and Outcomes Research (ISPOR) guidelines to produce the Lower Limb Functional Index-Polish version (LLFI-PL). The study recruited subjects (n=125, age =52.86±19.53 years, range 20-87, 56% female, injury duration =17.69±18.39 weeks, range 5-71). Baseline reliability and criterion validity included the LLFI-PL, Western Ontario and McMaster University Osteoarthritis Index (WOMAC), Euroqol Health Questionnaire 5-Dimensions (EQ-5D-5L), and an 11-point pain Numerical Rating Scale, with retest at 3-7 days. Practicality for readability was considered within the face and content validity. Completion and scoring time were also calculated. Results: Statistical analysis showed excellent internal consistency ( α =0.94) and high test-retest reliability (ICC=0.96). The error score found the SEM=3.49% with MDC 90 =8.11%. Validity analysis showed strong correlations between the LLFI-PL with the WOMAC (r=-0.81) and moderate with the EQ-5D-5L (r=-0.63). Exploratory factor analysis confirmed a single-factor structure. Times for completion (172±33 seconds) and scoring (20±9 seconds) were determined. Conclusions: The LLFI-PL is a psychometrically sound questionnaire for Polish-speaking patients with lower limb musculoskeletal conditions. The results support the findings of previous original-English, Spanish, and Turkish versions for internal consistency, validity, reliability, error score, and factor structure.

Introduction The Upper Limb Functional Index (ULFI) is a patient-reported outcome measure (PROM) designed to evaluate both the functional status and the level of participation in patients with upper limb musculoskeletal disorders (ULMSDs). The purpose of this study was translation, cross-cultural adaptation, and psychometric evaluation of the original ULFI into Persian (ULFI-Pr). Methods The original ULFI was translated into Persian through double forward and backward translations. Consecutive symptomatic upper limb patients (n = 180, male = 60%, age = 38.21 ± 7.13) were recruited and completed the ULFI-Pr and the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaires. Internal consistency and test-retest reliability were determined using Cronbach’s Alpha and the Intra-class Correlation Coefficient (ICC2.1). Criterion validity was analyzed by evaluating the Pearson’s r correlation coefficient between the ULFI-Pr and DASH questionnaires. Construct validity was examined through exploratory factor analysis (EFA) using Maximum Likelihood Extraction with Promax rotation. Results The original ULFI was translated and cross-culturally adapted into Persian with only minor wording changes. The ULFI-Pr demonstrated high levels of internal consistency (α = 0.91) and test-retest reliability (ICC2.1=0.92). The correlation between the ULFI and DASH was high (r = 0.71). The EFA demonstrated a one-factor structure that explained 38.2% of total variance. No floor or ceiling effects were observed. Conclusion The ULFI-Pr can be considered as a region-specific, single-factor structure PROM for evaluation of patients with upper limb disorders for clinical and research purposes in Persian language populations.

Affective Reactivity

Objective: To describe the cross-cultural adaptation of the Affective Reactivity Index (ARI) to Brazilian Portuguese and to investigate preliminary psychometric properties of the adapted version. Methods: Cross-cultural adaptation was based on the investigation of the theoretical and operational equivalences of the original ARI in the Brazilian context, followed by a process of translation, back-translation, and review by a committee of experts. Data analysis was carried out in a community sample of 133 schoolchildren aged 8 to 17 years to investigate the following characteristics of the ARI: 1) factor structure; 2) internal consistency; 3) construct validity comparing differential relationships between irritability and anxiety dimensions and impairment; and 4) item response theory (IRT) parameters. Results: A final Brazilian Portuguese version of the instrument was defined and is presented. Internal consistency was good, and our analysis supported the original single-factor structure of the ARI. Correlations of the ARI with distress-related anxiety dimensions were higher than with phobic-related anxiety dimensions, supporting its construct validity. In addition, higher ARI scores were associated with higher irritability-related impairment. IRT analysis underscored frequency of loss of temper as essential to inform about pathological states of irritability. Conclusion: The Brazilian Portuguese version of the ARI seems to be very similar to the original instrument in terms of conceptual, item, semantic, and operational equivalence. Our preliminary analysis replicates and extends previous evidence confirming promising psychometric properties for the ARI.
