INTRODUCTION
The literature lacks formally validated and reliable tools for the diagnosis of breakthrough cancer pain (BTcP). The Italian Questionnaire for BTcP diagnosis (IQ-BTP) is an 11-item questionnaire aimed at detecting potential-BTP and classifying it into three likelihood classes: high, intermediate, and low.
METHODS
A multicenter, prospective, and observational study was designed to validate the IQ-BTP. In three consecutive visits with each cancer patient, the demographic and clinical details of the patient, the Brief Pain Inventory (BPI) scores, IQ-BTP outcomes, and clinicians' autonomous BTcP diagnosis (gold standard) and the agreement of this diagnosis with IQ-BTP outcomes were recorded. The assessed domains for IQ-BTP validation were: Validity, including content and face validity, construct validity (hypothesis testing, and cross-cultural validity\measurement invariance), and criterion validity; Reliability (internal consistency, reliability, and measurement error); Interpretability, and Responsiveness.
RESULTS
Seven palliative and pain management facilities in Italy recruited 280 patients, yielding 753 evaluations. Using the IQ-BTP, the rate of potential-BTcP was 27.2%, of which its likely presence was high in 52.7% of patients, intermediate in 38.5, and low in 8.8%. The BPI item scores differed significantly between the two IQ-BTP classes (no-BTcP and potential-BTcP classes). The correlation of the latter class with BPI items was significant but low. The IQ-BTcP showed two principal components, accounting for 66.6% of the variance. Cronbach's α was 0.71. The agreement rate between the gold standard and IQ-BTP outcomes was 82%. Cohen's [Formula: see text] was 0.535. The IQ-BTP showed sensitivity and specificity of 69 and 86%, respectively.
CONCLUSIONS
The IQ-BTP extensive formal validation showed satisfactory psychometric and validity properties. Its content, face, construct, and criterion validities and its reliability, interpretability, and responsiveness were shown. Its use enabled potential-BTcP to be identified and differentiated into three likelihood classes with direct therapeutic and epidemiological implications. The latter may be confirmed in future studies.

Review
Osteoporotic fractures (OF) are a global public health problem currently. Many risk prediction models for OF have been developed, but their performance and methodological quality are unclear. We conducted this systematic review to summarize and critically appraise the OF risk prediction models. Three databases were searched until April 2021. Studies developing or validating multivariable models for OF risk prediction were considered eligible. Used the prediction model risk of bias assessment tool to appraise the risk of bias and applicability of included models. All results were narratively summarized and described. A total of 68 studies describing 70 newly developed prediction models and 138 external validations were included. Most models were explicitly developed (n=31, 44%) and validated (n=76, 55%) only for female. Only 22 developed models (31%) were externally validated. The most validated tool was Fracture Risk Assessment Tool. Overall, only a few models showed outstanding (n=3, 1%) or excellent (n=32, 15%) prediction discrimination. Calibration of developed models (n=25, 36%) or external validation models (n=33, 24%) were rarely assessed. No model was rated as low risk of bias, mostly because of an insufficient number of cases and inappropriate assessment of calibration. There are a certain number of OF risk prediction models. However, few models have been thoroughly internally validated or externally validated (with calibration being unassessed for most of the models), and all models showed methodological shortcomings. Instead of developing completely new models, future research is suggested to validate, improve, and analyze the impact of existing models.

BACKGROUND
The Menstrual Distress Questionnaire (MDQ) is a commonly used questionnaire that assesses various symptoms and distress associated with the menstrual cycle in women. However, the questionnaire has not been completely translated into Chinese with rigorous reliability and validity testing.
METHODS
This study translated the Menstrual Distress Questionnaire Form Cycle (MDQC) from English into Chinese: MDQCC in two stages. First, it was translated forward and backward using Jones' model; second, to test the validity and reliability, 210 Chinese-speaking women were recruited through online announcements and posters posted between June 2019 and May 2020. Expert validity, construct validity, convergent validity, and factorial validity were determined using content validity index (CVI), intraclass correlation coefficient (ICC), composite reliability (CR), and exploratory factor analysis, respectively. For concurrent criterion validity, MDQCC score was compared with three existing pain scales. Reliability was evaluated using internal consistency across items and two-week test-retest reliability over time.
RESULTS
The CVI for content validity was .92. Item-CVI for expert validities among the 46 items ranged from .50 - 1; scale-CVI for the eight subscales, from .87 - 1; ICC, from .650 - .897; and CRs, from .303 - .881. Pearson correlation coefficients between MDQCC and short-form McGill pain questionnaire, present pain intensity, and visual analog scale scores were .640, .519, and .575, respectively. Cronbach's α for internal consistency was satisfactory (.932). ICC for test-retest reliability was .852 for the entire MDQCC.
CONCLUSION
MDQCC was valid and reliable for Mandarin Chinese-speaking women. It can be used to evaluate female psychiatric symptoms related to the menstrual cycle in future work.

International Ophthalmology Nov 2022To translate, cross-culturally adapt and validate the Computer Vision Syndrome Questionnaire (CVS-Q) into Persian.
PURPOSE
To translate, cross-culturally adapt and validate the Computer Vision Syndrome Questionnaire (CVS-Q) into Persian.
METHODS
This study was carried out in 2 phases: (1) the CVS-Q was translated and cross-culturally adapted into Persian and (2) the validity and reliability of CVS-Q FA were assessed in a cross-sectional validation study. An expert committee composed of 15 optometrists evaluated content validity (item-level (I-CVI) and scale-level (S-CVI) content validity index were calculated). A pretest was performed (n = 20 participants) to verify the comprehensibility of the questionnaire. A total of 102 computer users completed the final questionnaire. Criterion validity and diagnostic performance of the CVS-Q FA were assessed by calculating sensitivity, specificity and receiver characteristic operator curve. Cronbach's alpha was calculated for the assessment of internal consistency and 46 participants refilled the questionnaire for the second time and the interclass correlation coefficient (ICC) and Cohen's kappa (κ) were evaluated for test-retest reliability.
RESULTS
The translation and cross-cultural adaptation process was performed successfully according to accepted scientific recommendations without any major difficulties. The I-CVI was above 0.80 for all items (symptoms) except item 15 (feeling that sight is worsening) and the S-CVI was 0.92. The CVS-Q FA showed good sensitivity (81.1%) and acceptable specificity (69.2%). Also, it achieved good internal consistency (Cronbach's alpha = 0.80) and test-retest reliability (ICC = 0.81 and κ = 0.65).
CONCLUSION
The CVS-Q FA was successfully translated, cross-culturally adapted, and validated into Persian. This study provides a valid and reliable tool for the assessment of computer vision syndrome among the Iranian working population.

OBJECTIVE
Central-line-associated bloodstream infection (CLABSI) surveillance in home infusion therapy is necessary to track efforts to reduce infections, but a standardized, validated, and feasible definition is lacking. We tested the validity of a home-infusion CLABSI surveillance definition and the feasibility and acceptability of its implementation.
DESIGN
Mixed-methods study including validation of CLABSI cases and semistructured interviews with staff applying these approaches.
SETTING
This study was conducted in 5 large home-infusion agencies in a CLABSI prevention collaborative across 14 states and the District of Columbia.
PARTICIPANTS
Staff performing home-infusion CLABSI surveillance.
METHODS
From May 2021 to May 2022, agencies implemented a home-infusion CLABSI surveillance definition, using 3 approaches to secondary bloodstream infections (BSIs): National Healthcare Safety Program (NHSN) criteria, modified NHSN criteria (only applying the 4 most common NHSN-defined secondary BSIs), and all home-infusion-onset bacteremia (HiOB). Data on all positive blood cultures were sent to an infection preventionist for validation. Surveillance staff underwent semistructured interviews focused on their perceptions of the definition 1 and 3-4 months after implementation.
RESULTS
Interrater reliability scores overall ranged from κ = 0.65 for the modified NHSN criteria to κ = 0.68 for the NHSN criteria to κ = 0.72 for the HiOB criteria. For the NHSN criteria, the agency-determined rate was 0.21 per 1,000 central-line (CL) days, and the validator-determined rate was 0.20 per 1,000 CL days. Overall, implementing a standardized definition was thought to be a positive change that would be generalizable and feasible though time-consuming and labor intensive.
CONCLUSIONS
The home-infusion CLABSI surveillance definition was valid and feasible to implement.

BACKGROUND
Self-efficacy concerns individuals' beliefs in their capability to exercise control in specific situations and complete tasks successfully. In people with multiple sclerosis (PwMS), self-efficacy has been associated with physical activity levels and quality of life. As a validated German language self-efficacy scale for PwMS is missing the aims of this study were to translate the Unidimensional Self-Efficacy Scale for Multiple Sclerosis (USE-MS) into German, establish face and content validity and cultural adaptation of the German version for PwMS in Austria. A further aim was to validate the German USE-MS (USE-MS-G) in PwMS.
METHODS
Permission to translate and validate the USE-MS was received from the scale developers. Following guidelines for translation and validation of questionnaires and applying Bandura's concept of self-efficacy, the USE-MS was forward-backward translated with content and face validity established. Cultural adaptation for Austria was performed using cognitive patient interviews. Reliability was assessed using Cronbach's alpha, Person separation index and Lin's concordance correlation coefficient. Rasch analysis was employed to assess construct validity. Comparison was made to scales for resilience, general self-efficacy, anxiety and depression, multiple sclerosis fatigue and health-related quality of life. Data were also pooled with an historic English dataset to compare the English and German language versions.
RESULTS
The translation and cultural adaptation were successfully performed in the adaptation process of the USE-MS-G. Pretesting was conducted in 30 PwMS, the validation of the final USE-MS-G involved 309 PwMS with minimal to severe disability. The USE-MS-G was found to be valid against the Rasch model when fitting scale data using a bifactor solution of two super-items. It was shown to be unidimensional, free from differential item functioning and well targeted to the study population. Excellent convergent and known-groups validity, internal consistency, person separation reliability and test-retest reliability were shown for the USE-MS-G. Pooling of the English and German datasets confirmed invariance of item difficulties between languages.
CONCLUSION
The USE-MS-G is a robust, valid and reliable scale to assess self-efficacy in PwMS and can generate interval level data on an equivalent metric to the UK version.

The Agency, Resources, and Institutional Structures for Sanitation-related Empowerment (ARISE) Scales: Development and validation of measures of women's empowerment in urban sanitation for low- and middle-income countries.
Sustainable Development Goal 6 aims to ensure access to water and sanitation for all, and target 6.2 emphasizes "paying special attention to the needs of women and girls". Research documenting how water, sanitation and hygiene (WASH) conditions impact women's and girls' lives is growing. However, no rigorously validated survey instruments exist for measuring empowerment within the WASH sector. The objective of our study was to develop and validate survey instruments to measure sub-domains of women's empowerment in relation to sanitation in urban areas of low- and middle-income countries. We followed a multi-phased, theory-informed approach that included factor analysis and item response theory methods, as well as reliability and validity testing, to analyze cross-sectional data collected from women in two cities: Tiruchirappalli, India (N = 996) and Kampala, Uganda (N = 1,024). Through rigorous evaluation of conceptually grounded question (item) sets, we identify a set of valid, comprehensive scales. The Agency, Resources, and Institutional Structures for Sanitation-related Empowerment (ARISE) scales represent 16 sub-domains of sanitation-related empowerment, each of which can be used alone or in combination with others, as needed. The ARISE scales are the only set of psychometrically validated metrics for the measurement of women's empowerment in WASH. In addition to the scales, we provide six indices to assess women's direct experiences with sub-domains of sanitation-related empowerment, as well as validated item sets related to menstruation, which are available as optional add-on measures for those who menstruate. The ARISE scales and associated survey modules respond to an established need for an increased focus on empowerment in WASH. We provide researchers and implementers with tools to measure sub-constructs of empowerment in a valid and reliable way, to generate data for better targeting, design, implementation, and evaluation of strategies to improve women's empowerment in the context of urban sanitation at the program and policy level.

OBJECTIVES
Health literacy (HL) about healthy cognitive aging is essential in preventing cognitive decline and promoting cognitive well-being. It is important that one such HL module should be scientifically designed, delivered in a technically sound manner to the audience, and specific to the context. The present study thus aimed at developing and validating educational multimedia about cognitive health.
METHODS
The study followed a methodological framework and was carried out across three phases, that is, identification of themes, development and validation of educational script and design, and validation of educational multimedia. The module was scripted based on the Integrated HL framework and the recommendations made during the modified nominal group technique among the research team. Seven speech-language pathologists (SLPs), with expertise in the field of cognitive sciences, and 15 representatives of the general public validated the module using the Educational Content Validation Instrument in Health and the Patient Education Materials Assessment Tool for Audiovisual Materials questionnaire.
RESULTS
The scientific content of the educational script received satisfactory agreements among the experts (content validity index [CVI]: 0.93) and representatives of the general public (CVI: 0.86). The technical aspects of the educational multimedia were rated to have high understandability (experts: 92.8%; representatives of general public: 98.8%) and actionability (experts and representatives of general public 100%).
CONCLUSION
Overall, the developed educational multimedia scored optimally with respect to the objective, structure, relevance of the content, actionability and understandability of the multimedia. The developed module holds the potential to be used at community and national level health educational programs or awareness campaigns to enhance public knowledge and beliefs pertaining to cognitive health.
PATIENT OR PUBLIC CONTRIBUTION
SLPs with expertise in the field of cognitive science and representatives from the general public were included to validate and obtain feedback on the developed educational multimedia.

Recent experimental and theoretical studies have shown that the assessment of students' satisfaction of their basic psychological needs () can be a powerful resource to identify different areas to improve their well-being, engagement, or learning achievement in school contexts. However, currently, the number of validated tools to assess the satisfaction of the BPN is very low, hindering informed decision-making strategies at the educational level. The aim of this study was to develop and validate the Basic Psychological Needs in the Classroom Scale (BPN-CS) instrument, adapting existing instruments and putting the new tool to the test. The BPN-CS was developed to measure the level of satisfaction of autonomy, competence, relatedness, and novelty in the classroom. We tested the scale on a representative sample of 1344 Spanish elementary school students from 8 to 13 years old. A series of analyses were run in order to test the internal consistency of the main factors as well as to prove the convergent and divergent validity of the instrument. In summary, the BPN-CS is presented as a reliable and valid self-report instrument to measure basic psychological needs in a classroom context with elementary school pupils in the Spanish context.

Employability is an important issue in the labor context. Currently, the European Union presents employability as the path to full employment and active citizenship, and a strategy to reduce unemployment and poverty. This study develops and validates an Employability Appraisal Scale. Specifically, we propose a multidimensional employability scale that analyzes both individual indicators and personal circumstances from the Bioecological Model of Employability. The Employability Appraisal Scale (EAS) assesses personal and social dimensions of employability. It was developed and tested using data from 489 people from a very heterogeneous sample (precarious workers, professionals, prisoners, long-term unemployed, socially excluded, etc.). Results provide evidence for the multi-dimensional structure and validity of the EAS. This scale is a valid and reliable instrument to measure employability, and it provides criteria for interpreting scores. Finally, we present theoretical and practical implications of the EAS for social and labor integration, job transition, and career development. Our findings have positive implications for identifying effectiveness indicators in training programs, and they contribute to designing intervention policies to increase employability.
