INTRODUCTION
Currently, daytime sleepiness is a prevalent condition worldwide. Locally validated instruments for measuring sleepiness are required. The objective of this study was to validate a version of the Karolinska sleepiness scale that was translated into the Spanish spoken in Colombia.
METHODS
Individuals who attended a sleep laboratory for a polysomnography study and people in the general population were included. The validation process was performed in 6 phases: translation and back translation of the original version of the scale (English), face validity (n=13), pilot test (n=20), criteria validity (n=139) by means of polysomnography and the Epworth sleepiness scale, reproducibility (n=34), and sensitivity to change (n=40).
RESULTS
Regarding its discriminant validity, the Colombian version of the Karolinska sleepiness scale is correlated with the Epworth sleepiness scale, provided that a Mann-Whitney z=2661 (p=0.0078) was obtained. The scale has an acceptable reproducibility, Spearman Rho=0.55 (p=0.0002), and sensitivity to change, as shown through a two-tailed t test (p=0.0000).
CONCLUSIONS
The Karolinska Sleepiness Scale was successfully adapted to the Spanish variation spoken in Colombian and to the conditions of adult Colombians; thus, it constitutes a valid, reliable, and easy to use instrument for the assessment of patients with hypersomnia.

PloS One 2022To develop, validate and evaluate a computerized clinical decision support system (MedReview) that aids medication reviewers with pharmacological decision-making.
OBJECTIVES
To develop, validate and evaluate a computerized clinical decision support system (MedReview) that aids medication reviewers with pharmacological decision-making.
METHODS
This study included three phases; the development phase included computerizing a consolidated medication review algorithm (MedReview), followed by validation and evaluation of MedReview and responding to a web-based survey designed using patient scenarios. Participants had to be 'fully registered' with the Malaysian Pharmacy Board and work full-time at a community pharmacy.
RESULTS
MedReview was developed as a web app. It was validated among 100 community pharmacists from May-July 2021 using the Technology Acceptance Model (TAM). There was acceptable content validity and fair inter-rater agreement, and good convergent and discriminant validity. Exploratory factor analysis resulted in five domains to determine the attitude of pharmacists about using MedReview: perceived ease of use, perceived usefulness, intention to use, trust, and personal initiatives and characteristics; the total variance explained by five factors was 76.36%. The survey questionnaire had a high overall reliability value of 0.96. Evaluation of MedReview was based on mean scores of survey items. Of all items included in the survey, the highest mean score (out of 7) was achieved for 'I could use MedReview if it is meaningful/relevant to my daily tasks' (5.78 ± 1.10), followed by 'I could use MedReview if I feel confident that the data returned by MedReview is reliable' (5.77 ± 1.21), and 'I could use MedReview if it protects the privacy of its users' (5.73 ± 1.20).
CONCLUSION
Community pharmacists generally had a positive attitude towards MedReview. They found that MedReview is trustworthy and they had the intention to use it when conducting medication reviews. The adaptation of the TAM in the survey instrument was reliable and internally valid.

BACKGROUND
Moral courage as a part of nurses' moral competence has gained increasing interest as a means to strengthen nurses acting on their moral decisions and offering alleviation to their moral distress. To measure and assess nurses' moral courage, the development of culturally and internationally validated instruments is needed.
OBJECTIVE
The objective of this study was to validate the Dutch-language version of the four-component Nurses' Moral Courage Scale originally developed and validated in Finnish data.
RESEARCH DESIGN
This methodological study used non-experimental, cross-sectional exploratory design.
PARTICIPANTS AND RESEARCH CONTEXT
A total of 559 nurses from two hospitals in Flanders, Belgium, completed the Dutch-language version of the Nurses' Moral Courage Scale.
ETHICAL CONSIDERATIONS
Good scientific inquiry guidelines were followed throughout the study. Permission to translate the Nurses' Moral Courage Scale was obtained from the copyright holder, and the ethical approval and permissions to conduct the study were obtained from the participating university and hospitals, respectively.
FINDINGS
The four-component 21-item, Dutch-language version of the Nurses' Moral Courage Scale proved to be valid and reliable as the original Finnish Nurses' Moral Courage Scale. The scale's internal consistency reliability was high (0.91) corresponding with the original Nurses' Moral Courage Scale validation study (0.93). The principal component analysis confirmed the four-component structure of the original Nurses' Moral Courage Scale to be valid also in the Belgian data explaining 58.1% of the variance. Confirmatory factor analysis based on goodness-of-fit indices provided evidence of the scale's construct validity. The use of a comparable sample of Belgian nurses working in speciality care settings as in the Finnish study supported the stability of the structure.
DISCUSSION AND CONCLUSION
The Dutch-language version of the Nurses' Moral Courage Scale is a reliable and valid instrument to measure nurses' self-assessed moral courage in speciality care nursing environments. Further validation studies in other countries, languages and nurse samples representing different healthcare environments would provide additional evidence of the scale's validity and initiatives for its further development.

Review
OBJECTIVE
We conducted a systematic review of the literature about quality-of-life (QOL) scales in chronic venous disorders (CVDs) comprising leg ulcers to identify the respective advantages and deficits of existing tools.
METHODS
A research protocol was built following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement and the PICO (population, intervention, comparator, and outcome) criteria. The following databases were screened: MEDLINE, SCOPUS, EMBASE, CINHAL, and Cochrane. Psychometric and linguistic validation studies in English were included, as were clinical trials that have used QOL scales in CVDs. The data search was up to date as of October 31, 2013.
RESULTS
Inclusion criteria were met in 103 of the 511 recorded references, in which 10 scales were identified: two for the full spectrum of CVDs, three for patients with CVDs without leg ulceration, four for leg ulcers, and one exclusively for patients with varicose veins. Among them, the ChronIc Venous Insufficiency Questionnaire (CIVIQ), Aberdeen Varicose Vein Questionnaire (AVVQ), and VEnous INsufficiency Epidemiological and Economic Study on Quality of Life (VEINES-QOL) scales were the most highly used according to the literature, and CIVIQ and VEINES-QOL were the most extensively validated scales and had the longest iterative validation process. A total of 31 psychometric and linguistic validations of the 10 QOL scales and 66 clinical trials that have used these scales were identified. The validation studies were based on acceptability, content validity, construct validity, reliability, and responsiveness. The clinical trials were composed of 25 randomized controlled trials and 41 observational studies. Only the randomized controlled trials are considered in the present article.
CONCLUSIONS
This systematic review confirmed that CVDs have an important effect on QOL. The majority of the studies addressed the application rather than the validation of the 10 identified scales. Two scales, CIVIQ and VEINES-QOL, emerged as being thoroughly validated instruments, although factorial stability was not demonstrated for the VEINES-QOL. Our findings confirm a paucity of validation studies.

BACKGROUND
Preconception care helps to close the gaps in a continuum of care. It is of paramount importance to reduce maternal and child adverse pregnancy outcomes, increase the utilization of services such as antenatal care, skilled delivery care, and post-natal care, and improve the lives of future generations. Therefore, a validated instrument is required. The purpose of this study was to develop and validate the preconception care improvement scale (PCIS) in a resource-limited setting.
METHODS
A mixed-method study was carried out from 02, March to 10, April 2019 in Manna district, Oromia region, Ethiopia to test the reliability and validity of the scale. Items were generated from literatures review, in-depth interviews with different individuals, and focused group discussions with women of reproductive age groups. A pretested structured questionnaire was used and a survey was conducted among 623 pregnant women in the district. The collected data were entered into EPI-data version 3.1 software and exported to SPSS version 23 software and data were analyzed for internal consistency and validity using reliability analysis and factor analysis.
RESULTS
The PCIS has 17 items loaded into six factors: Substance-related behaviors, screening for common non-communicable and infectious diseases, micronutrient supplementation and vaccination, seeking advice, decision and readiness for conception, and screening for sexually transmitted diseases. Factor analysis accounted for 67.51% of the observed variance. The internal consistency (Cronbach's alpha) of the scale was 0.776. Diversified participants of the qualitative study and experts' discussions assured the face and content validity of the scale. Factor loading indicated the convergent validity of the scale. Three of the PCIS subscale scores had a positive and significant association with the practice of preconception care and antenatal care visits, which confirmed the predictive validity of the scale.
CONCLUSION
The PCIS exhibited good reliability, face validity, content validity, convergent validity, and predictive validity. Thus, the scale is valid and helps to improve preconception care, especially in resource-limited settings.

Voxelwise disconnection mapping is a novel approach to disclose lesion-symptom relationships for symptoms caused by white matter disconnection. It uses MRI-based fiber tracking in healthy subjects seeded from patient's focal brain lesions. Resulting individual disconnection maps can then be statistically associated with symptoms. Despite increasing use in the recent years, the validity of this approach remains to be investigated. In this study, we validated both, our own implementation and the implementation provided within BCBtoolkit. For technical validation, we used simulated symptoms based on overlap of 70 real stroke lesions with tracts from a white matter atlas. For clinical validation, paresis scores and lesions from 316 patients with stroke were used. We found that voxelwise disconnection mapping is technically valid and outperforms the standard voxel-based lesion-symptom mapping approach for symptoms caused by white matter disconnection. Supporting its clinical validity and utility, we were able to reproduce the known association between corticospinal tract damage and contralateral hemiparesis. In addition, we demonstrate that the validity can be substantially diminished by relatively minor methodological changes. Based on these results, we derive methodological recommendations for the future use of voxelwise disconnection mapping. Our study highlights the importance of validating novel methodological approaches in the rapidly evolving field of neuroimaging.

BMC Oral Health Jun 2024To developed and evaluate the validity, reliability, and Arabic translation of a questionnaire for preadolescent perception to removable functional appliances.
OBJECTIVE
To developed and evaluate the validity, reliability, and Arabic translation of a questionnaire for preadolescent perception to removable functional appliances.
SUBJECTS AND METHODS
A new questionnaire was drafted based on previously used questionnaires. Twelve orthodontic experts were selected within content and face validity panel and twenty preadolescents wearing functional appliances were participated in the face validation of the questionnaire. Two rounds of content validity were performed with the same experts. The final form of the validated questionnaire was translated from English to Arabic language. The content validity index (CVI) was used for content validity and the Cronbach's alpha test was used to assess the internal consistency reliability of the questionnaire.
RESULTS
During the first round of content validity, 50 items were relevant to the underlying construct (Item-CVI ≥ 0.78), while four items were considered not valid (Item-CVI < 0.78) and the average scale-CVI was 0.93. In terms of face validation by experts, the percentage of agreement was adequate (96.4%). The questionnaire was modified by removing the non-valid items, adding/modifying items, and merging some categories. For second round of content validity, all items were found to be valid (I-CVI ≥ 0.78) and the overall questionnaire had adequate content validity (Scale-CVI/Ave = 0.94). The translated valid questionnaire also achieved a perfect agreement (100%) for face validity by patients. The internal consistency was appropriate (≥ 0.7).
CONCLUSIONS
A new valid, reliable, and translated questionnaire (English and Arabic versions) that cover the majority of aspects of patients' perception during treatment with removable functional appliances has been developed.

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.

Towards the transition to blended and remote education, evaluating the levels of students' digital competence and designing educational programs to advance them is of paramount importance. Existing validated digital competence scales usually ignore either important digital skills needed or new socio-technological innovations. This study proposes and validates a comprehensive digital competence scale for students in higher education. The suggested instrument includes skills of online learning and collaboration, social media, smart and mobile devices, safety, and data protection. The scale was evaluated on a sample of 156 undergraduate and postgraduate students just before and at the beginning of the COVID-19 crisis. The final scale is composed of 28 items and six digital competence components. The evaluation study revealed valid results in terms of model fit criteria, factor loadings, internal validity, and reliability. Individual factors like the students' field of study, computer experience and age revealed significant associations to the scale components, while gender revealed no significant differences. The suggested scale can be useful to the design of new actions and policies towards remote education and the digital skills' development of adult learners.

Review
OBJECTIVE
To identify validated questionnaires to assess medication adherence, and its associated factors, in adult patients with chronic pathologies.
METHOD
A systematic review of scientific publications that describe validated medication adherence questionnaires in PubMed and Scopus was carried out during May 2022. The search strategy combined the MeSH Heading "Medication adherence" with the keywords: "Questionnaire" and "Validation"; adding "Spanish" to rescue questionnaires in our language. Systematic reviews, meta-analyses or scientific articles with full text available in Spanish or English were selected; published from January 2000 to April 2022; that present the application and validation of a medication adherence questionnaire in adults with chronic pathologies; and publications of the initial validation of a questionnaire, recovered through bibliographic citations of the previously identified publications, even if they are prior to the year 2000. The PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines were followed to represent the search process, inclusion and exclusion of the retrieved publications.
RESULTS
Ninety-seven records in PubMed and 3 adding "Spanish" were retrieved; in Scopus, 334 records were retrieved and 13 with "Spanish". One hundred-eighteen records were retrieved through bibliographic citations identification. From the analysis of the previous publications, 14 validated questionnaires were identified that assess medication adherence and are applied in English and/or Spanish in adult patients with chronic pathologies. For each questionnaire, the following characteristics were described: name, authors, year of publication, dimensions (barriers and facilitators factors), number and wording of the items, response scale, form of administration, language and pathologies of the initial validation. Of the subsequent validations, only those carried out in English and/or Spanish were presented. So far, 6 questionnaires were validated in Spanish and only for certain chronic pathologies.
CONCLUSIONS
14 validated questionnaires were identified, 6 of them were validated in Spanish. They are designed to evaluate medication adherence in a comprehensive manner, being useful to be applied in hospital and community pharmaceutical services. This review provides health professionals with tools to develop and validate their own questionnaire, adapting the wording to the local language and context of the health system.
