This study aimed to determine the validity of specific knee varus alignment measurement methods. We measured the femorotibial angle (FTA) using radiography and optical motion capture and validated the FTA measurement using markerless motion capture. The subjects included 34 legs of 19 patients with knee osteoarthritis (OA). One-way analysis of variance and multiple comparison tests were used to compare the FTA values between the Kellgren-Lawrence classification (KL) and Pearson's correlation coefficient for validity. The analysis showed that the FTA measured by markerless motion capture had a significant correlation to the FTA measured by radiography (r = 0.869, < 0.01) and significantly increased with increasing KL ( < 0.05). These results indicate that markerless motion capture is a valid outcome measure for varus alignment in patients with knee OA.

BACKGROUND
The Mini Nutrition Assessment (MNA) is a widely used and valid tool for screening and assessment of malnutrition among the elderly population worldwide. However, MNA has not been validated among the Ethiopian elderly population and this study assessed the validity of the tool for the target population.
METHODS
Cross-sectional validation study design employed to validate MNA in Meki town, East Ethiopia. This study included 176 randomly selected elders living in the community, whereas amputated, bedridden, visible deformity, known liver and/or renal disorders were excluded. The original MNA questionnaires were translated to local language and administered to each participant after doing the pretest. The anthropometric, self-perception of nutritional status and serum albumin concentrations were measured. Reliability, validity, sensitivity, specificity, Positive Predictive Value (PPV), and Negative Predictive Value (NPV) were calculated. Receiver-operating characteristic (ROC) curve analysis was plotted to identify the area under the curve (AUC) and optimal cut-off value for the prediction of malnutrition.
RESULT
A total of one hundred and seventy-six elders participated in this study. Of the total participants, 78(44.3%) were males. The mean (SD) age of the participants was 67.6 (±5.8) years and ranged from 60 to 84 years. The prevalence of malnutrition based on the MNA criteria (MNA < 17 points) was 18.2%, and 13.1% based on serum albumin concentration (<3 g/dl).The MNA had an overall Internal consistency of Cronbach's alpha 0.61. The tool also demonstrated significant criterion-related validity (0.75, < 0.001) and concurrent validity (0.51, < 0.001) with serum albumin concentration and self-perception of nutritional status respectively. Using the original cut-off point, the sensitivity, specificity, PPV and NPV of the tool were 93.5%, 44.6%, 65.4% and 86.0%, respectively. By modifying, the cut-off point to a value of <20.5, the sensitivity and specificity of the tool increases to 97.6% and 82.8% respectively. The AUC (95%CI) showed an overall accuracy of 92.7% (88.5, 96.9).
CONCLUSION
The MNA tool can be used as a valid malnutrition screening tool for the Ethiopian elderly population by modifying the original cut-off point.

Journal of Surgical Education 2015To systematically review literature pertaining to microsurgical skill assessment tools to determine those specific to, and validated for, microsurgery training. (Review)
Review
OBJECTIVES
To systematically review literature pertaining to microsurgical skill assessment tools to determine those specific to, and validated for, microsurgery training.
DESIGN
Multiple databases were searched with preset terms. The search dates included all years up to May 2014. The eligibility criteria included the presence of statistical comparison with a control group and the presence of a measure of validation. The articles and their references were independently reviewed by 2 assessors. Each assessment tool was evaluated for content, construct, face, and criterion validities as well observation/expectant bias and interrater/intrarater reliability. For individual studies, we screened for expectant and selection bias.
RESULTS
Of the 261 articles reviewed, 10 articles and 1 abstract were included. Those excluded were predominantly assessment tools that did not evaluate microsurgical skill or articles where no assessment tool was described. The assessment tools identified in this review include a self-assessment tool where trainees rate their skill confidence from 1 to 5, stereoscopic visual acuity as a predictor for microsurgical performance, an objective motion-tracking electronic device--the Imperial College of Surgical Assessment Device, and 6 global rating scales. Content, construct, and face validities were consistently demonstrated in addition to observation/expectant bias and interrater reliability. Criterion validity was only demonstrated for half of the instruments and intrarater reliability for only 1.
CONCLUSIONS
Overall, 10 articles and 1 abstract described validated methods. Reliability and validity were demonstrated by 6 global rating scales (University of Western Ontario microsurgical skills acquisition, structured assessment of microsurgery skills, and video-based objective structured assessment of technical skill). Motion analysis using the Imperial College of Surgical Assessment Device is a valid objective measure of skill.

Review
BACKGROUND
Persuasive design principles are increasingly employed in mHealth apps for motivating users and promoting healthy behaviours among individuals. However, how the persuasive design principles are perceived by the mHealth app users remains unclear.
AIM
To develop and validate the content validity of an instrument designed to measure the user's perceptions of the persuasive design principles assimilated in a breastfeeding mHealth app.
METHODS
A critical review of the literature guided the development of the research instrument. The developed instrument was refined and validated through a two-round modified Delphi process. Ten experts drawn from academic and clinical settings evaluated the items through two content validity indicators, relevance, and clarity and provided narrative feedback. The content validity of the instrument was determined by calculating the Content Validity Index (CVI). Content validity indicators at the scale-level (S-CVI) and item-level (I-CVI) were calculated.
RESULTS
The results demonstrated high content validity index of individual items in the instrument. All items in the instrument reached an excellent I-CVI ≥ 0.78 for both relevance and clarity except one item. The overall content validity index of the instrument using the average approach was moderate to high (S-CVI/Ave was 0.89 and 0.92 for relevance and clarity, respectively). The developed research instrument is composed of 5 constructs representing 24 items: (1) primary task support, (2) dialogue support, (3) system credibility support, (4) social support and (5) perceived persuasiveness.
CONCLUSIONS
Using a modified Delphi approach, the development and validation of the research instrument demonstrated moderate to high content validity for measuring users' perceptions of the persuasive design principles assimilated in a breastfeeding mHealth app. The evidence from this study supports that the research instrument is valid, relevant, and clear.

BACKGROUND
This study aimed to translate and validate an Arabic version of the Functional Assessment of Cancer Therapy Head and Neck Scale (FACT-H&N, v-4) for use among Sudanese oral cancer patients.
METHODS
The instrument underwent translation and validation following the standard FACT translation methodology. The translated instrument was pre-tested for face validity and content validity using semi-structured, in-depth interviews with ten oral cancer patients to assess acceptability. The questionnaire was pilot tested with 60 patients; reliability was tested for internal consistency with Cronbach's alpha while construct validity was tested using 'known-group validity'.
RESULTS
The pre-test study revealed no major issues, apart from a reluctance to answer questions on sexual satisfaction. The FACT-H&N demonstrated good internal consistency, it considered five particular constructs: PWB, SWB, EWB, FWB and FACT-H&N, their Cronbach's α values were positive and close to 1 with values of 0.85, 0.788, 0.86, 0.895 and 0.703 respectively, indicating that the questionnaire was valid and the responses consistent. Sixty patients were asked the global health-related quality of life item, 36.3% rated their QOL as very good or good (36.3%), while 41.7% rated it as average, and 21.7% as poor or very poor. Then FACT subscale mean scores were tabulated against three categories; patients with very poor/poor recorded significantly lower scores indicating construct validity. Some psychometric properties were consistent with other FACT-H&N translations such as the Chinese, French, Pakistani and Malaysian.
CONCLUSIONS
This study validates the Arabic version of the FACT-H&N. It is a reliable tool and, will assist further QoL research in other Arabic-speaking countries.

BACKGROUND
There is a lack of standardized assessment tools for poststroke aphasia in Brazil, particularly bedside screenings for early identification of patients with suspected language disorders. The Language Screening Test (LAST) is a valid and reliable method for screening hospitalized patients following a stroke. This tool was first developed in French and then translated and validated in other languages.
PURPOSE
This study aimed to translate, culturally adapt, and validate the LAST into Brazilian Portuguese.
METHOD
Following a systematic, multistep approach to translation and cultural adaptation of language instruments, this study developed the two parallel versions of the Brazilian Portuguese LAST (pLAST) Versions A and B. The final versions were applied to 70 healthy and 30 poststroke adults across age and educational levels. Subtests of the Boston Diagnostic Aphasia Examination (BDAE) were used to assess the external validity of the pLAST.
RESULTS
Findings showed that the two versions (A and B) of the pLAST were equivalent (intraclass correlation coefficient = .91; < .001). No floor or ceiling effects were observed, and internal validity was excellent (Cronbach's α = .85). Moreover, its external validity against the BDAE was moderate to strong. Test sensitivity and specificity were 0.88 and 1, respectively, and accuracy was 0.96.
CONCLUSION
The Brazilian Portuguese version of the LAST is a valid, simple, easy, and rapid test to screen poststroke aphasia in hospital settings.

BACKGROUND
In recent years, health centers in the United States have embraced the opportunity to train the next generation of health professionals. The uniqueness of the health centers as teaching settings emphasizes the need to determine if health professions training programs align with health center priorities and the nature of any adjustments that would be needed to successfully implement a training program. We sought to address this need by developing and validating a new survey that measures organizational readiness constructs important for the implementation of health professions training programs at health centers where the primary role of the organizations and individuals is healthcare delivery.
METHODS
The study incorporated several methodological steps for developing and validating a measure for assessing health center readiness to engage with health professions programs. A conceptual framework was developed based on literature review and later validated by 20 experts in two focus groups. A survey-item pool was generated and mapped to the conceptual framework and further refined and validated by 13 experts in three modified Delphi rounds. The survey items were pilot-tested with 212 health center employees. The final survey structure was derived through exploratory factor analysis. The internal consistency reliability of the scale and subscales was evaluated using Chronbach's alpha.
RESULTS
The exploratory factor analysis revealed a 41-item, 7-subscale solution for the survey structure, with 72% of total variance explained. Cronbach's alphas (.79-.97) indicated high internal consistency reliability. The survey measures: readiness to engage, evidence strength and quality of the health professions training program, relative advantage of the program, financial resources, additional resources, implementation team, and implementation plan.
CONCLUSIONS
The final survey, the Readiness to Train Assessment Tool (RTAT), is theoretically-based, valid and reliable. It provides an opportunity to evaluate health centers' readiness to implement health professions programs. When followed with appropriate change strategies, the readiness evaluations could make the implementation of health professions training programs, and their spread across the United States, more efficient and cost-effective. While developed specifically for health centers, the survey may be useful to other healthcare organizations willing to assess their readiness to implement education and training programs.

BACKGROUND
Ancient history mentions the dominance of men in nursing; however, now nursing has a feminine image, and globally more than 90% of nursing workforce is females. Recently, more number of males are attracted to nursing, but there is a paucity of literature on the attitude of people about men in nursing may be because of a lack of measurement scales available for this purpose. The aim of this study was to develop and validate a new scale measuring attitude of people toward men in nursing.
MATERIALS AND METHODS
The present study was conducted at a tertiary care hospital and used an exploratory sequential design with an instrument development model. A total of 400 participants were selected using the simple random sampling technique. The reliability, content validity, face validity, and construct validity of this newly developed scale were computed. For data analyses SPSS AMOS version 23 was used for performing exploratory and confirmatory factor analyses.
RESULTS
The new scale "AMnQ" consists of 15 items under three factors: (I) nursing is feministic and professionally low, (II) higher suitability of male nurses in technical and challenging situations, and (III) synonymy of empathy and care with a female. The final model with 15 items of AMnQ scale was validated by confirmatory factor analysis and showed a good fit to data. The Cronbach's α for the overall scale was 0.87, and for Factors I, II, and III, it was 0.80, 0.88, and 0.89, respectively.
CONCLUSIONS
The "AMnQ" is a valid, reliable scale to assess the attitude of patients, nurses, physicians, and nursing students toward men in nursing. There is an assumption that nursing is a feminine profession; therefore, a valid and reliable scale to measure the attitude of people toward men in nursing will help to generate pieces of evidence on this subject, so that policymakers can make unbiased decisions on liberalizing entry of men in nursing.

Every human being has the right to safe, dignified and harm-free care in health institutions. High fidelity simulation has been used in teaching for the training and continuing education of health professionals to promote quality, safe and humanized patient care. Elaborating scenarios is an important phase to provide a simulation-based experience, and is relevant in the teaching-learning process. The objective of this study was to validate the content and applicability of the High Fidelity Simulation Scenario Planning and Development Form and its Operational Manual. The form could be used to development of scenarios to medicine, nursing, physiotherapy and as well as other specialties in the healthcare. This was a methodological validation study of the form and its manual content by experts in simulation and its feasibility, conducted in two phases: Phase 1: eight experts were selected using the "snowball" sampling technique to validate the content measured by the content validity index; Phase 2 (test): the form and its operational manual validated by the experts were made available to 28 participants in order to elaborate scenarios for the feasibility assessment and participation in the focus group. All items in the form and in the operational manual reached a content validity index above 0.80. The total content validity index was 0.98. The evaluation of the usability of the instruments carried out by the participants reached a percentage above 96.43% in all alternatives except for the item "It was easy to use the form to build your scenario" (75%). Eight participants were present in the focus group. Focus group discussions were categorized into completeness, practicality and usefulness according to comments and suggestions. The form and its operational manual proved to be valid instruments.
