Background: Prosthetic socket fit is an important element associated with successful ambulation and use of a prosthesis. Prosthetists and rehabilitation clinicians would benefit from an assessment tool that discriminates between and quantifies the multiple determinants that influence the lower limb amputee’s performance and satisfaction of a prosthetic socket. Objectives: To determine the internal consistency of the comprehensive lower limb amputee socket survey, a new self-report measure of prosthetic socket satisfaction that quantifies suspension, stability, comfort, and appearance. Study design: Cross-sectional sample of active amputees. Methods: Interviews were conducted with prosthetists, physical therapists, and lower limb amputees to identify clinical concerns and common activities influencing socket fit. An expert panel of five clinicians reviewed the items and constructed the original version of the comprehensive lower limb amputee socket survey which was then administered to a convenience sample of 47 active lower limb amputees. Item analysis and Cronbach’s alpha were used to determine the final version of the comprehensive lower limb amputee socket survey. Results: Following item raw score-to-total score correlation with Cronbach’s alpha for comprehensive lower limb amputee socket survey determinants, internal consistency improved when nine questions were eliminated. Conclusion: The comprehensive lower limb amputee socket survey is a self-report measure of prosthetic socket satisfaction with very good internal consistency. Clinical relevance When socket problems occur, the ability to determine the specific cause can reduce modification time, enhance socket fit, and promote patient satisfaction. A standardized multi-dimensional assessment measure of socket satisfaction enables prosthetists to quantify the multiple determinants of socket satisfaction, improve patient communication, and demonstrate the value of socket interventions.

Abstract Background: The Middle East Lower Limb Score (MELLS) is an adaptation of the WOMAC questionnaire, specifically adjusted according to the cultural issues of the middle eastern patients with Knee or hip disabilities. The primary objective of this study was to verify if the translation and adaptation of the MELLS into Arabic could be used with ease and consistency by Arab-speaking patients suffering lower limb disabilities.Methods: 110 participants were involved in this study. We performed the internal consistency tests with Cronbach’s alpha. We also calculated floor effects, ceiling effects, as well as test-retest reliability (intra-correlation coefficient). To estimate the validity of MELLS, we used two validated questionnaires – WOMAC and OHS. We confirmed the validity of MELLS questionnaire using Spearman’s correlation.Results: MELLS had a Cronbach’s alpha of 0.88 in the first assessment and 0.92 in the second assessment, which was very high and reliable. Both subscales of MELLS had an internal consistency higher than 0.85. No relevant ceiling and floor effect were observed among the responses. Furthermore, strong significant correlation with WOMAC subscales and OHS was observed, which suggested a good construct validity. Responsiveness of MELLS, however, proved to be lower (but not considerably) than other two questionnaires.Conclusion: The Arabic Middle East Lower Limb Score (MELLS) is a useful and reliable diagnostic tool for Middle eastern patients with knee and hip problems.

There is evidence of the effectiveness of implementing mental health literacy (MHL) programs. However, there are substantial limitations in the instruments available for measuring MHL. This study aimed to develop and validate the EspaiJove.net MHL test (EMHL) for Spanish adolescents by assessing its psychometric properties. The development of the EMHL test was conducted using item pool generation and a pilot study. A convenience sample of students aged 13–15 years (n = 355) participated in the validity study. Reliability was assessed for internal consistency and via test-retest. Convergent validity was evaluated by comparing the effect sizes among known groups with different levels of mental health knowledge, the correlation with mental health-related instruments, and the item discrimination index. A final version of a 35-item EMHL test was obtained with two parts: (i) a binary choice format (yes/no) for the identification of mental disorders; (ii) a multiple choice question with four possible answer options. Internal consistency was acceptable in the first part (Cronbach’s alpha = 0.744; Guttman’s lambda 2 = 0.773) and almost acceptable in the second part (Cronbach’s alpha = 0.615; Guttman’s lambda 2 = 0.643). The test-retest evaluation supported the stability of the test (first part, ICC = 0.578; second part, ICC = 0.422). No ceiling and floor effects were found. The EMHL test scores discriminated between known groups with different levels of mental health knowledge and it is associated with several-related constructs of MHL. Conclusions: The EMHL test is a relevant measure for assessing MHL in adolescents into Spanish context with acceptable validity and stability.

Translation And Validation

Dysphagia may become a threatening condition if not diagnosed and treated at an early stage. Healthcare professionals require simple, rapid, and reliable tools for the immediate evaluation of dysphagia in their daily clinical practice. The aim of the present study was the translation and validation of the “Brief Bedside Dysphagia Screening Test-Revised (BBDST-R)” tool in the Greek language in a sample of patients with neurological disorders. The present study was designed as a cross-sectional study conducted with a convenience sample of 80 patients. The BBDST-R tool contains eight items, and a positive response to an item implies that the patient might have dysphagia. The bedside assessment using the BBDST-R tool was conducted by a researcher previously trained for the tool usage. The translation and validation were conducted by following the relevant international standards. The researcher’s final assessment concerning the presence or absence of dysphagia was compared to the medical diagnosis as determined by a physician, which was set as a benchmark. The evaluation of BBDST-R was conducted by researching its diagnostic accuracy according to the guidelines for measures of diagnostic accuracy. Internal consistency was determined through Cronbach’s Alpha. The English version of the BBDST-R tool has been reliably translated into the Greek language. The prevalence of dysphagia in our sample was 62.5% (95% CI: 50%-72%). The observed high sensitivity [Sen = 98%/87%-99% (95% CI)] and high negative predictive value [NPV = 89%/77%-95% (95% CI)] indicated high validity of the screening tool at the acceptable levels of > 75% even for 95% CI. Cronbach’s Alpha internal consistency index for the 8 items of this tool presented an almost excellent value of 0.859. The results of the present study indicated that BBDST-R is a reliable and valid tool for application in the assessment of dysphagia in patients admitted in Greek hospitals and community-based individuals.

Background: Functional status is a critically important outcome measure after stroke. The ability to electronically capture this through self-report is increasing. The Patient Reported Outcomes Measurement Information System (PROMIS) uses computer adaptive testing (CAT), which can increase score precision and reduce patient burden. The number of questions depends on the patient’s responses. The objective of this study was to evaluate the performance of the PROMIS physical function scale (PROMIS PF) compared to the validated Stroke Impact Scale 16 (SIS16) in an ambulatory stroke clinic. Methods: Patient-reported PROMIS PF (CAT version) and SIS16 were electronically collected on patients seen in the stroke clinic using the Knowledge Program platform. Patient completion rates were > 70%. Distribution of scores was compared to assess ceiling/floor effects. Internal consistency was assessed by calculating the SEM for PROMIS PF and Cronbach’s alpha for SIS16. Correlations with NIHSS were performed to assess convergent validity. Results: The PROMIS PF and SIS16 were collected on 5,691 patients from Jan 2010 - May 2014. Mean SIS16 score = 81.4 (SD 21.5), mean PROMIS PF score = 42.8 (SD 11.2). The SIS16 had a22% ceiling effect, <1 % ceiling effect was seen with PROMIS PF (Figure). Patients completed 16 SIS16 items and a median of 4 [IQR 4, 5] PROMIS PF items. Cronbach’s alpha for SIS16 = 0.959, SEM for PROMIS PF = 2.3; both values suggest excellent internal consistency. Test-retest correlation was 0.867 for SIS16 and 0.87 for PROMIS PF. Correlations between NIHS and the 2 scales were -0.461 (p<0.001) for PROMIS PF and -0.559 (p<0.0001) for SIS16. Conclusion: The use of the PROMIS system to obtain electronic patient-reported functional status in ambulatory stroke clinic is feasible. PROMIS PF is an option for measurement of physical function in patients with stroke. It had similar test characteristics as the SIS16 but with lower patient burden and no ceiling effect.

Background: The Comprehensive Lower limb Amputee Socket Survey (CLASS) is a self-reported measure developed to assess prosthetic socket fit in individuals with lower limb amputation. Objective: To assess the reliability and validity of the Persian version of the CLASS. Study Design: Cross-sectional and repeated-measures. Methods: We evaluated the translation and back translation of the CLASS and made the required changes according to expert committee feedback. Then, we recruited 124 participants with unilateral lower limb amputation (89.5% men). Internal consistency was analyzed with Cronbach’s alpha and test–retest reliability using intra-class correlation coefficients. Convergent construct validity was assessed by comparing the CLASS scores with the Persian version of the Trinity Amputation and Prosthesis Experience Scales (TAPES) scores. In addition, known groups construct validity was assessed by comparing CLASS scores between groups with different causes and levels of amputation. Results: Cronbach’s alpha coefficient represented a very good internal consistency for all domains of the Persian CLASS (ranged from 0.86 to 0.92). The intra-class correlation coefficient for test–retest reliability for the Persian CLASS was good to excellent (ranged from 0.73 to 0.97). There was a significant correlation between the subscales of the Persian CLASS and satisfaction subscales of the Persian TAPES ( p < 0.001). There was no significant difference between the Persian CLASS scores by cause or level of amputation. Conclusion: The Persian CLASS is a reliable and valid measure for evaluating prosthetic socket fit.

The Multiple Sclerosis Work Difficulties Questionnaire-23 (MSWDQ-23) is a self-report instrument developed to assess barriers faced by People with Multiple Sclerosis (PwMS) in the workplace. The aim of this study was to explore the psychometric properties of the Greek version of the MSWDQ-23. The study sample consisted of 196 PwMS, all currently working in part- or full-time jobs. Participants underwent clinical examination and cognitive screening with the Brief International Cognitive Assessment for Multiple Sclerosis (BICAMS) and completed self-report measures of fatigue, psychological functioning, and quality of life, along with the MSWDQ-23 questionnaire. Confirmatory Factor Analysis (CFA) was performed, and goodness-of-fit measures were used to evaluate construct validity. Convergent validity was checked by correlating MSWDQ-23 scores with study measures. Cronbach’s alpha value was produced to assess internal consistency. CFA yielded a model with a fair fit confirming the three-factor structure of the instrument. Higher work difficulties were associated with higher Expanded Disability Status Scale (EDSS) scores, poorer cognitive function, more fatigue, stress, anxiety, and depression, and poorer health status, supporting the convergent validity of MSWDQ-23. Internal consistency (Cronbach’s alpha = 0.94) and test–retest reliability (ICC = 0.996, 95%, CI = 0.990–0.998) were excellent. The Greek MSWDQ-23 can be considered a valid patient-reported outcome measure and can be used in interventions aiming to improve the vocational status of PwMS.

Cardiac rehabilitation is supported by the highest level of scientific evidence. However, less than 25% of those eligible to participate in a cardiac rehabilitation program initiate it; and of these, 50% drop out prematurely. A modified Spanish Cardiac Rehabilitation Barriers Scale (CRBS) has been translated, culturally adapted and validated in Colombia, however, the reliability remains to be evaluated. This study aimed to determine the internal consistency and test–retest reliability of the CRBS in a Colombian population. In total, 193 patients (67% men, average age = 65 ± 12 years) completed the scale twice, with an average of eight days between applications. Cronbach’s Alpha and intraclass correlation coefficients (ICC) were calculated. The internal consistency of the Colombian version of the CRBS was acceptable (Cronbach’s alpha = 0.84). The ICC of the CRBS was 0.69 (95% CI 0.61–0.76); 0.78 (95% CI 0.71–0.84) when the CRBS was completed by interview; and 0.47 (95% CI 0.21–0.67) when the CRBS was self-reported. The reliability of the interview version of the CRBS was substantial in the Colombian population; however, the reliability of the self-report version was lower. The use of this scale will allow developing strategies to increase participation and adherence to cardiac rehabilitation programs.

Abstract Background Many frequently used instruments fail to assess psychosocial functioning in patients with bipolar disorder. The Functioning Assessment Short Test (FAST) was developed in order to tackle this problem and to assess the main functioning problems experienced by patients with bipolar disorder. However, the original FAST is not fully applicable in older adults due to the domain of occupational functioning. The aim of our study was to validate an adapted version for Older adults (FAST-O) in a group of older adults with bipolar disorder (OABD). Methods 88 patients aged 50 years and over diagnosed with bipolar disorder were included. We adapted the items in the area of “work-related functioning” of the FAST into items assessing “societal functioning”. Several measurements were conducted in order to analyse the psychometric qualities of the FAST-O (confirmatory factor analysis for internal structure, Cronbach’s alpha for internal consistency, Spearman’s rho for concurrent validity, Mann–Whitney U test for discriminant validity). Results Mean age in the study sample was 65.3 (SD = 7.5) and 57.3% was female. The internal structure was most similar to the internal structure of the original FAST. The internal consistency was excellent (Cronbach’s alpha = .93). The concurrent validity when correlated with the Social and Occupational Functioning Assessment Scale was low, but significant. The FAST-O was also able to distinguish between euthymic and symptomatic OABD patients. Conclusions The FAST-O has strong psychometric qualities. Based on our results, we can conclude that the FAST-O is a short, efficient solution in order to replace global rating scales or extensive test batteries in order to assess daily functioning of older psychiatric patients in a valid and reliable manner.

Abstract Background Studies of psychological distress in Sierra Leone have typically used measures which were developed for use in other contexts, and which often have not been adapted or validated for use in Sierra Leone. This has resulted in a lack of reliable information about the patterns of psychological distress within the population, which is a barrier to the development of effective and appropriate mental health services. The aim of the study was to develop a locally-appropriate measure of psychological distress for Sierra Leone. Methods The new measure consists of two instruments: the Sierra Leone Psychological Distress Scale (SLPDS) and a gendered measure of ability to carry out daily tasks—a Function scale—as an indication of the severity of distress. A three-phase mixed methods exploratory sequential study was conducted. Phase 1 was item generation and testing, leading to the development of a set of potential items for both instruments. Phase 2 was a small pilot study (N = 202) leading to the selection of the final set of items for both measures. Phase 3 was a validation phase where the SLPDS and the Function scale were administered with a larger sample of 904 respondents. Item analysis was used to assess the internal consistency of the scales, and Exploratory Factor Analysis to explore the properties of the SLPDS. Results Exploratory factor analysis using the principal axis factoring with an oblique rotation identified a three-factor structure for the 18-item SLPDS. Internal consistency for the SLPDS (Cronbach’s alpha = 0.89) and three subscales was good (Cronbach’s alpha > 0.73). The internal reliability of the male and female versions of the Function scale was also found to be acceptable (Cronbach’s alpha = 0.90 for the female scale and 0.79 for the male scale). Conclusions Together the SLPD and Function scales provide a locally-validated tool which will enable government bodies and local and international non-governmental organisations in Sierra Leone to assess mental health and psychosocial needs. This will support both effective service provision and the evaluation of initiatives designed to improve mental health and psychosocial wellbeing.
