Given its highly contagious nature and an absence of a specific antiviral agent to this date, the key to controlling the spread of coronavirus disease 2019 (COVID-19) and decreasing the infection rate is adherence to preventive measures. It is essential to understand an individual's knowledge, attitudes and practices toward COVID-19 since public adherence to health guidelines relies heavily on these aspects. However, there is no validated instrument that evaluates knowledge, attitudes and practices toward COVID-19. Thus, this study aimed to develop and validate such tool. A questionnaire was developed based on international and national guidelines and a review of the literature. Initial items were evaluated by 10 experts to determine content validity. Exploratory factor analysis and reliability testing were conducted with a convenience sample of 229 nursing students. Based on the content, face validity and factor analysis, 34 items were selected. The Kaiser-Meyer-Olkin value of 0.735 indicated a highly acceptable score with a significant Bartlett's test of sphericity ( < 0.0001). The internal consistency coefficients indicated acceptable reliability of the tool (Cronbach's α = 0.75). The KAP COVID-19 is a valid instrument that can be used to evaluate knowledge, attitudes and practices toward COVID-19.

Review
BACKGROUND
Functional rating scales allow clinicians to document and quantify alterations and progression of recovery processes. There is neither awareness of numerous knee scales nor are they easy to find or compare to select the most suitable.
OBJECTIVES
We aimed to compile validated knee functional rating tools and analyze the methodological quality of their validation studies. Also, we aimed to provide an operational document of the outcome measures addressing descriptions of parameters, implementations, instructions, interpretations and languages, to identify the most appropriate for future interventions.
METHODS
A systematic review involved a search of PubMed, Web of Science, CINAHL, Scopus, and Dialnet databases from inception through September 2020. The main inclusion criteria were available functional rating scales/questionnaires/indexes for knees and validation studies. Methodological quality was analyzed with the Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2) and COnsensus-based Standards for the selection of health Measurement Instruments Risk of Bias (COSMIN-RB).
RESULTS
We selected 73 studies. The studies investigated 41 knee rating tools (general, 46%, and specific, 54%) and 71 validations, including 29,742 individuals with knee disorders. QUADAS-2 obtained the best results in patient selection and index test (applicability section). COSMIN-RB showed the highest quality in construct validity (most analyzed metric property). The specific tools were mainly designed for prosthesis and patellofemoral and anterior cruciate ligament injuries. More considered issues were specific function (93%), especially gait, pain/sensitivity (81%), and physical activity/sports (56%).
CONCLUSIONS AND IMPLICATIONS
We conducted a necessary, useful, unlimited-by-time and feasible compilation of validated tools for assessing knee functional recovery. The methodological quality of the validations was limited. The best validations were for the Copenhagen Knee Range of Motion Scale in osteoarthritis and arthroplasties, Knee Outcome Survey Activities of Daily Living and Lysholm Knee Score for general knee disorders and the Tegner Activity Score for anterior cruciate ligament injuries. The operational document for the scales provides necessary data to identify the most appropriate.

Information bias is common in epidemiology and can substantially diminish the validity of study results. Validation studies, in which an investigator compares the accuracy of a measure with a gold standard measure, are an important way to understand and mitigate this bias. More attention is being paid to the importance of validation studies in recent years, yet they remain rare in epidemiologic research and, in our experience, they remain poorly understood. Many epidemiologists have not had any experience with validations studies, either in the classroom or in their work. We present an example of misclassification of a dichotomous exposure to elucidate some important misunderstandings about how to conduct validation studies to generate valid information. We demonstrate that careful attention to the design of validation studies is central to determining how the bias parameters (e.g. sensitivity and specificity or positive and negative predictive values) can be used in quantitative bias analyses to appropriately correct for misclassification. Whether sampling is done based on the true gold standard measure, the misclassified measure or at random will determine which parameters are valid and the precision of those estimates. Whether or not the validation is done stratified by other key variables (e.g. by the exposure) will also determine the validity of those estimates. We also present sample questions that can be used to teach these concepts. Increasing the presence of validation studies in the classroom could have a positive impact on their use and improve the validity of estimates of effect in epidemiologic research.

OBJECTIVE
Most current Misophonia scales are not validated, do not include both emotional and physiological responses to triggers, and/or focus only on auditory triggers. This research aimed to develop and validate a measure of the magnitude of the Misophonic response that addressed these omissions.
METHOD
Three studies were carried out with individuals with self-diagnosed Misophonia. In study 1, expert opinion and participants commented on initial items to determine both face and content validity. In study 2, scale structure, reliability, and convergent and discriminant validity were determined using correlations, principal component analysis (PCA), and reliability analysis. In study 3, factor structure was confirmed in another sample of participants using confirmatory factor analysis (CFA).
RESULTS
The final 22-item scale assesses the magnitude of responses to triggers across any sensory modality. There are three subscales (emotional, physiological, and participation in life), with three additional items measuring frequency of triggers, avoidance of triggers, and time taken to recover from the triggers. The final scale showed suitable discriminant and convergent validity, with good internal consistency (Cronbach's alphas range 0.77 to 0.89). The three-component solution extracted using PCA explained 53.97% of variance, with all items loading between 0.45 and 0.84. The structure was confirmed with CFA (χ = 269.01, p < .001; CFI = 0.96; TLI = 0.96 and RMSEA = 0.045 (CI 0.037-0.053).
CONCLUSION
The Misophonia Response Scale, which is valid and reliable, will facilitate understanding of Misophonia as it is short and easy to use for self-report in research.

The purpose of this study was to develop and validate the Intention for Warm-up among Children and Adolescents Scale (IWCAS). There were four phases and four sets of participants in the development of the IWCAS. In the first phase, the domains of intention were defined, and related components were developed, organized, and validated. In the second phase, 446 elementary and middle school students participated in a pilot study for the first version of the scale, which was revised based on the information obtained. In the third phase, 12 graduates in sports pedagogy served on an expert panel and organized the items into domain areas and developed a second version of the IWCAS. In the final phase, 1322 elementary and middle school students from three k-12 schools completed the revised version of the IWCAS, and exploratory and confirmatory factor analyses were conducted. Based on the results, the IWCAS was shortened by deleting some items in two domains; this resulted in 11 items of the final version with 3 domains: (1) attitude toward warm-up, (2) subjective norm, and (3) perceived behavioral control that, according to the indices, generate reliable and structurally valid scores. The composite internal consistency for the three domains ranged from 0.74 to 0.85. The researchers hypothesized the IWCAS is a valid and reliable scale, which can be used by P.E. teachers or coaches to evaluate the intention of primary and secondary school students to perform warm-ups.

BACKGROUND
Improving health literacy has become one of the most important public health-related goals at the global level; however, there is no clear consensus on measurement of health literacy. Despite numerous health literacy scales available in Turkish, none of the existing scales was originally developed and validated at a national level.
OBJECTIVE
This study aimed to develop and validate a culturally appropriate original health literacy scale (HLS) to be used as a reference for the Turkish-speaking literate adult population in Turkey and abroad.
METHODS
Two multidisciplinary workshops with more than 20 experts were conducted and a large item pool was developed. The first and second draft of the scale were pre-tested with 20 and 150 adults, respectively, from different age groups and socioeconomic levels in Ankara. The validity and reliability study of the revised scale (110 items plus 20 self-efficacy statements) was carried out with a household survey of 2,411 adults in 12 randomly selected provinces from 12 Nomenclature of Territorial Units for Statistics Regions in Turkey. Explanatory and confirmatory factor analysis were performed. The fit indices were obtained. The item analysis was applied, and Cronbach's alpha statistics were obtained.
KEY RESULTS
The scale was found to be both a valid and a reliable measurement tool to assess health literacy. Cronbach's alpha for two sub-dimensions ("disease prevention and health promotion" and "treatment and access to health services") were 0.79 and 0.91, respectively. Construction validity indices were Root Mean Square Error of Approximation (RMSEA) = 0.043, Goodness of Fit Index (GFI) = 0.96, Normed Fit Index (NFI) = 0.95, and Adjusted Goodness of Fit Index (AGFI) = 0.95. The scale includes "self-efficacy" as an additional dimension (Cronbach's alpha = 0.83, RMSEA = 0.68, GFI = 0.94, NFI = 0.94, and AGFI) = 0.91).
CONCLUSION
HLS is a valid and reliable measurement tool to assess health literacy of Turkish-speaking literate adults with a mixed (objective and subjective) assessment approach. Plain Language Summary: This study aimed to develop and validate a culturally sensitive original health literacy scale to be used as a reference scale for the Turkish-speaking literate adult population in Turkey and abroad. Study findings showed that HLS is both a valid and a reliable measurement tool to assess health literacy of Turkish-speaking literate adults.

Review
BACKGROUND
Workplace-based learning is a critical component of professional preparation in speech pathology. A validated assessment of this learning is seen to be 'the gold standard', but it is difficult to develop because of design and validation issues. These issues include the role and nature of judgement in assessment, challenges in measuring quality, and the relationship between assessment and learning. Valid assessment of workplace-based performance needs to capture the development of competence over time and account for both occupation specific and generic competencies.
AIMS
This paper reviews important conceptual issues in the design of valid and reliable workplace-based assessments of competence including assessment content, process, impact on learning, measurement issues, and validation strategies. It then goes on to share what has been learned about quality assessment and validation of a workplace-based performance assessment using competency-based ratings. The outcomes of a four-year national development and validation of an assessment tool are described.
METHODS & PROCEDURES
A literature review of issues in conceptualizing, designing, and validating workplace-based assessments was conducted. Key factors to consider in the design of a new tool were identified and built into the cycle of design, trialling, and data analysis in the validation stages of the development process.
OUTCOMES & RESULTS
This paper provides an accessible overview of factors to consider in the design and validation of workplace-based assessment tools. It presents strategies used in the development and national validation of a tool COMPASS, used in an every speech pathology programme in Australia, New Zealand, and Singapore. The paper also describes Rasch analysis, a model-based statistical approach which is useful for establishing validity and reliability of assessment tools.
CONCLUSIONS & IMPLICATIONS
Through careful attention to conceptual and design issues in the development and trialling of workplace-based assessments, it has been possible to develop the world's first valid and reliable national assessment tool for the assessment of performance in speech pathology.

Review
New computer technologies, like virtual reality (VR), have created opportunities to study human behavior and train skills in novel ways. VR holds significant promise for maximizing the efficiency and effectiveness of skill learning in a variety of settings (e.g., sport, medicine, safety-critical industries) through immersive learning and augmentation of existing training methods. In many cases the adoption of VR for training has, however, preceded rigorous testing and validation of the simulation tool. In order for VR to be implemented successfully for both training and psychological experimentation it is necessary to first establish whether the simulation captures fundamental features of the real task and environment, and elicits realistic behaviors. Unfortunately evaluation of VR environments too often confuses presentation and function, and relies on superficial visual features that are not the key determinants of successful training outcomes. Therefore evidence-based methods of establishing the fidelity and validity of VR environments are required. To this end, we outline a taxonomy of the subtypes of fidelity and validity, and propose a variety of practical methods for testing and validating VR training simulations. Ultimately, a successful VR environment is one that enables transfer of learning to the real-world. We propose that key elements of psychological, affective and ergonomic fidelity, are the real determinants of successful transfer. By adopting an evidence-based approach to VR simulation design and testing it is possible to develop valid environments that allow the potential of VR training to be maximized.

INTRODUCTION
Internalized stigma among people living with HIV has been linked to a range of negative consequences. The current study describes the development and validation of a contextually appropriate internalized HIV-related Stigma Scale for people living with HIV in Thailand.
METHODS
The study was carried out in two stages from 2018 to 2019: developing items based on the findings of focus group discussions and pilot testing the original list of items and validating the instrument. In the cross-sectional survey stage, a sample of 400 people living with HIV was used to validate the test items in accordance with their psychometric characteristics.
RESULTS
The study's outcome was the 22-item Thai Internalized HIV-related Stigma Scale (Thai-IHSS). The exploratory factor analysis showed that the Thai-IHSS consisted of four components: negative thoughts toward self (5 items), anticipated negative thoughts (7 items), effects of negative thought toward self (6 items), and effects of negative thoughts toward family and access to healthcare services (4 items).
DISCUSSION
The Thai-IHSS had acceptable concurrent, convergent, and congruent validity according to the findings. Additionally, the 8-item Thai-IHSS brief, which included two items for each component, was detailed. The Thai-IHSS is valid and reliable for use in Thailand and other countries with comparable sociocultural environments.

Background is a frequent and challenging problem that may impact a patient's postoperative pain and satisfaction. The level of a patient's anxiety needs to be assessed through a valid and reliable instrument to prevent and treat preoperative anxiety effectively. One such reliable measurement scale is Amsterdam Preoperative Anxiety and information scale, which is based on a self-reported questionnaire but is still not validated in Arabic. Objective To validate the Arabic Version of the Amsterdam Preoperative Anxiety and Information Scale (APAIS) for assessing preoperative anxiety in the Arabic population. Methods A cross-sectional study was conducted to translate and evaluate the validity of the APAIS in the Arabic version. The targeted population was Saudi adults undergoing surgery at the King Fahad Hospital in the Qassim region of Saudi Arabia. One hundred hospital patients were recruited and given the APAIS questionnaire to collect the data. The ethical considerations have been appropriately followed to protect the privacy of the patient's history. The collected data was qualitative and quantitative, which were analyzed using Statistical Package for the Social Sciences (SPSS). Results The questionnaire showed high internal consistency on the anxiety scale (Cronbach's alpha: 0.851) and a strong correlation between age, chronic diseases, and surgery. While Cronbach's alpha for the information scale is 0.827. The gold standard curve between the worried and afraid two variables showed good efficiency during the configuration. In addition, the Confirmatory Factor Analysis (CFA) model of the Arabic version is a two-factor model to evaluate the validity of the Arabic version. Conclusion The Arabic Version of the Amsterdam Preoperative Anxiety and information scale (APAIS) is a valid and reliable instrument for assessing preoperative anxiety. Using this validated scale for Arabic patients is feasible and shows promising results.
