Assessing Teacher Accountability: Development and Validation of the Teacher’s Professional Accountability Scale (TPAS)

This study aims to develop and validate the Teachers’ Professional Accountability Scale (TPAS) constructed by the researcher, which addresses the need for a comprehensive tool to measure professional accountability among Secondary school teachers. Professional accountability is the obligation of educators to adhere established standards and practices with competence and integrity, is crucial for improving educational quality and ensuring favorable student outcomes. A descriptive survey method was employed, and the TPAS was constructed and standardized through a pilot study. The scale consists of 94 items across four dimensions: procedural responsibility, consequential responsibility, instructional responsibility, and school and classroom responsibilities for student outcomes. Item analysis and selection resulted in a final draft of 74 items with satisfactory discrimination power. Reliability analysis using split-half method and Cronbach’s alpha yielded coefficients of 0.85, indicating high internal consistency. Content validity was established through expert reviews, and norms were developed based on z-scores from a sample of 281 Secondary school teachers. The TPAS provides a validated measure for assessing professional accountability, contributing to the advancement of educational research and practice, The study reached some recommendations, including the commitment of the school administration and senior management to the accountability standards reached, and the provision of joint workshops to ensure the efficiency of the implementation of professional accountability standards for teachers.

Mapping design stages and methodologies for developing STEM concept inventories: a scoping review

BackgroundConcept inventories (CIs) have become widely used tools for assessing students’ learning and assisting with educational decisions. Over the past three decades, CI developers have utilized various design approaches and methodologies. As a result, it can be challenging for those developing new CIs to identify the most effective and appropriate methods and approaches. This scoping review aimed to identify and map key design stages, summarize methodologies, identify design gaps and provide guidance for future efforts in the development and validation of CI tools.MethodsA preliminary literature review combined theoretical thematic analysis (deductive, researcher-driven) focusing on specific data aspects, and inductive thematic analysis (data-driven), using emerging themes independent of specific research questions or theoretical interests. Expert discussions complemented the analysis process.ResultsThe scoping review analyzed 106 CI articles and identified five key development stages: define the construct, determine and validate content domain; identify misconceptions; item formation and response processes design; test item selection and validation; and test application and refinement. A descriptive design model was developed using a mixed-method approach, incorporating expert input, literature review, student-oriented analysis, and statistical tests. Various psychometric assessments were employed to validate the test and its items. Substantial gaps were noted in defining and determining the validity and reliability of CI tools, and in the evidence required to establish these attributes.ConclusionThe growing interest in utilizing CIs for educational purposes has highlighted the importance of identifying and refining the most effective design stages and methodologies. CI developers need comprehensive guidance to establish and evaluate the validity and reliability of their instruments. Future research should focus on establishing a unified typology of CI instrument validity and reliability requirements, as well as the types of evidence needed to meet these standards. This effort could optimize the effectiveness of CI tools, foster a cohesive evaluation approach, and bridge existing gaps.

A case study of the development of a valid and pragmatic implementation science measure: the Barriers and Facilitators in Implementation of Task-Sharing Mental Health interventions (BeFITS-MH) measure

BackgroundFew implementation science (IS) measures have been evaluated for validity, reliability and utility – the latter referring to whether a measure captures meaningful aspects of implementation contexts. We present a real-world case study of rigorous measure development in IS that assesses Barriers and Facilitators in Implementation of Task-Sharing in Mental Health services (BeFITS-MH), with the objective of offering lessons-learned and a framework to enhance measurement utility.MethodsWe summarize conceptual and empirical work that informed the development of the BeFITS-MH measure, including a description of the Delphi process, detailed translation and local adaptation procedures, and concurrent pilot testing. As validity and reliability are key aspects of measure development, we also report on our process of assessing the measure’s construct validity and utility for the implementation outcomes of acceptability, appropriateness, and feasibility.ResultsContinuous stakeholder involvement and concurrent pilot testing resulted in several adaptations of the BeFITS-MH measure’s structure, scaling, and format to enhance contextual relevance and utility. Adaptations of broad terms such as “program,” “provider type,” and “type of service” were necessary due to the heterogeneous nature of interventions, type of task-sharing providers employed, and clients served across the three global sites. Item selection benefited from the iterative process, enabling identification of relevance of key aspects of identified barriers and facilitators, and what aspects were common across sites. Program implementers’ conceptions of utility regarding the measure’s acceptability, appropriateness, and feasibility clustered across several common categories.ConclusionsThis case study provides a rigorous, multi-step process for developing a pragmatic IS measure. The process and lessons learned will aid in the teaching, practice and research of IS measurement development. The importance of including experiences and knowledge from different types of stakeholders in different global settings was reinforced and resulted in a more globally useful measure while allowing for locally-relevant adaptation. To increase the relevance of the measure it is important to target actionable domains that predict markers of utility (e.g., successful uptake) per program implementers’ preferences. With this case study, we provide a detailed roadmap for others seeking to develop and validate IS measures that maximize local utility and impact.

의사소통적 발음 교육을 위한 한국어 교재 분석 연구

Objectives The purpose of this paper is to analyze Korean textbooks for communicative pronunciation education. Methods Three types of textbooks developed by university-affiliated language education institutes were selected as analysis targets. As analysis tools, items that were synthesized and reconstructed from the textbook analysis frameworks of Seo (2001) and Lee (2001) were used. Results The result shows that the scope of teaching items was expanded, and it was necessary to secure areas equivalent to vocabulary and grammar, select teaching items for continuous and repetitive learning, and provide detailed grading. In addition, the educational effectiveness of the explicitness or implicitness of linguistic rule explanations had to be examined, and audiovisual materials should be abundantly utilized. The practice activities were planned to involve step-by-step practice from the word and sentence level to the discourse level, but the instructions were not clear, and even if there were directions, practice method was monotonous. For communicative pronunciation education, instructions and guidelines had to be specified and a variety of interactive and meaningful exercises had to be included. As for learning strategies, only simple repetition, memorization strategies, and strategies using visual images were induced. Effective pronunciation learning strategies should be found and learning strategies had to be developed in a variety of ways. Conclusions Considering practical application, a plan to revitalize pronunciation education was proposed while maintaining the current textbook. Improvement measures were discussed focusing on the practice stage. Integrated practice with other micro and macro skills and clear practice method instructions were emphasized. Practice and use were claimed at the word, sentence, and discourse levels in the order of presentation-controlled practice-meaningful practice-use. Interactive activities such as pair or group activities were considered.

Developing an Evidence-Based Primary Cancer Prevention Repository: insights from the PIECES project

Abstract Introduction Up to 40% of cancer cases could be avoided through effective primary prevention. However, cancer prevention tends to be fragmented across Europe, leading to geographical health differences. The dissemination and scale-up of effective primary cancer prevention interventions may address this. Although effective cancer prevention programs exist, finding them and their materials (especially regarding implementation) can be challenging. Repositories of evidence-based interventions provide insight into “what is out there” and can support dissemination within and across national borders. The PIECES project aims to develop and disseminate a repository of evidence-based primary cancer prevention programs adaptable to European contexts, with information to aid adaptation and implementation across countries. Methods The development of the PIECES repository has been informed by established repositories such as NCI’s Evidence-Based Cancer Control Programs. The project team developed a scoring sheet with a selection of items that could be included in the repository. All participants rated each item on relevance and applicability and provided comments and suggestions. A final framework, including a set of minimal requirement items, was agreed upon during three online consensus building meetings. Results We created a repository of evidence-based primary cancer prevention interventions targeting modifiable risk factors suitable for implementation in European healthcare settings. This 22-item repository provides information about an intervention’s logic model, implementation practices, and appraisal of published evidence of effectiveness. Conclusions This repository is innovative as it includes practical information and tools to facilitate implementation. While initially built to serve the PIECES project, the repository is designed to be a valuable tool for European policymakers, researchers, and implementers. Lessons learned from this process will inform future developers. Key messages • A comprehensive cancer prevention intervention repository avoids “reinventing the wheel” and allows for more efficient use of existing interventions by building upon the best available evidence. • The ongoing efforts of the PIECES project represent a significant contribution to reduce cancer prevention disparities and to facilitate the adoption of evidence-based interventions in Europe.

Cultural Considerations in Intelligence Test Adaptations: a Critical Review of the WAIS-IV India and Its U.K. and U.S. Counterparts.

This study critically examined the adaptation and normative processes of the Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV)India. WAIS-IV U.K. Edition Administration and Scoring Manual, WAIS-IVIndia Administration and Scoring Manual, and WAIS-IV Administration and Scoring Manual and Technical and Interpretive Manuals were used to extract test development and adaptation process data. The analyses were descriptive and qualitative. A review of the manuals showed that the normative sample were fluent English speakers with high education levels, which is not representative of India's multilingual and educational diversity. The study identified minimal cultural and linguistic adaptations in subtests, which raised concern about potential biases in the test adaptation process across cultures. The lack of clarity in item selection, demographic data, sample selection, and psychometric properties raised questions about the test's reliability and validity. Issues related to education, age, gender, and regional distribution are discussed, emphasizing the test's limitations in capturing the diverse characteristics of the heterogeneous Indian population. WAIS-IV India may not adequately represent India's population. More careful consideration of socioecological and psychometric factors when adapting intelligence (IQ) tests and use of advanced data harmonization methods can provide robust cross-national statistical harmonization in the future along with more ecologically valid local test development efforts. This can allow consideration of social determinants of health and other factors that can inform a more nuanced approach to IQ test development in non-western contexts.

CARD-SARC: mixed-method study to develop a disease-specific health-related quality of life tool for cardiac sarcoidosis

Abstract Introduction Sarcoidosis is a rare inflammatory condition caused by the formation of lumps (granulomas) of abnormal tissue in any organ, and can affect physical, functional, mental, social and economic aspects of life. People living with cardiac sarcoidosis (CS) are likely to have worse clinical outcomes and greater impairment on health-related quality of life (HRQoL) than other sarcoidosis manifestations. HRQoL is the main concern for people living with sarcoidosis. However, measuring HRQoL in people with CS is difficult as existing tools focus on other forms of sarcoidosis (for example, lung, eye or skin involvement) or for specific cardiac symptoms (for example, atrial fibrillation, angina or heart failure), but not specifically for CS. Purpose To develop a disease-specific patient-reported outcome measure (CARD-SARC) to assess the impact of CS on HRQoL. Methods A sequential exploratory mixed-method, multicentre observational cohort study using a clinimetric approach was conducted. The McMaster Framework for evaluative instruments involved three steps (item selection, item scaling and item reduction) which were complemented with recommendations from the consensus-based standards for the selection of health measurement instruments (COSMIN). The item-generation process connected data from quantitative (theory, research findings and systematic review) and qualitative components (qualitative semistructured interviews, clinical observations and experts’ opinion). A simultaneous triangulation (QUAN+qual) method was followed to ensure a comprehensive list of preliminary items. The formatting of items was guided by patient and public involvement (PPI) with a 2-weeks recall period. The item reduction strategy was led by PPI and an international multidisciplinary clinical CS-experts. Results 740 potential items were generated by converging all the different sources and techniques. After removal of duplicates and simultaneous triangulation, a preliminary list with 111 items was reviewed by the CS-expert panel with 26 members (including 11 pulmonologists, 7 cardiologists, 5 CS-patients and 3 specialist-nurses). After a consensus meeting, the CARD-SARC included 61 relevant items in six sections for pilot-testing: "functioning", "social, leisure and occupation", "emotional", psychological", "physical" and "healthcare/self-care". Conclusions This study combined a robust methodology with active PPI engagement to develop the first disease-specific HRQoL tool for CS. Each data source was planned independently, however the input from PPI members was critical during the simultaneous triangulation for item-generation. The contributions of CS-experts (members of the PPI group and clinical multidisciplinary experts) enhanced the content validity of the CARD-SARC. The CARD-SARC has the potential to influence clinical management and treatment options, future research and health-economic stakeholders’ decisions for CS.

Medical students attitudes towards patients with disability: a scale validation study

BackgroundDisparities in health outcomes among persons with disabilities (PWD) are influenced by preventable factors including negative attitudes and discriminatory practices of healthcare professionals and the limited training of medical students in working with PWD.ObjectiveThe purpose of this study was to validate the “Medical Students’ Attitudes Towards Patients with Disabilities” (MSA-PWD) scale among Lebanese medical students and identify associated factors.MethodA scale validation study was conducted as part of the standard internal evaluation process at the medical school, using a cross-sectional design based on a qualitative content validity process, involving students from years 1 to 4. The study included questions from previous tools, and others encouraging students to reflect on their encounters with PWD and share their insights. Statistical procedures were applied to assess the reliability and validity of the tool, including construct validity, convergent validity, known-group validity, and trend analysis.ResultsAfter a careful selection of the related items, the MSA-PWD scale demonstrated high construct validity and internal consistency, along with good convergent validity and known-group validity. Factor 1 of the scale was able to differentiate between different enrollment years of medical students, correlating with the self-assessment tool for confidence in dealing with PWD and clinical experience scenarios.ConclusionThe “Medical Students’ Attitudes Towards Patients with Disabilities” scale validated in this study is a comprehensive instrument that can distinguish between different medical school enrollment classes. The newly developed scale was valid, and reliable.

Exploring Youths’ Offers to Use E-Cigarettes in Rural Hawai‘i: A Test Development and Validation Study

The purpose of this study is to describe the development and initial validation of a survey focused on problematic situations involving e-cigarette use by rural Native Hawaiian and Pacific Islander (NHPI) youths. A 5-phase approach to test development and validation was used. In Phase 1 (Item Generation), survey items were created from a series of focus groups with middle school youths on Hawai‘i Island (N = 69). In Phase 2 (Item Refinement and Selection), situational items were reduced to 40 e-cigarette offer situations that were selected for inclusion in the survey. In Phase 3 (Item Reduction), items were administered to 257 youths from 11 middle, intermediate, or multi-level public or public-charter schools on Hawai‘i Island. Exploratory factor analysis indicated the presence of three factors accounting for 50% of the variance: E-Cigarette Offers from Friends (24%), E-Cigarette Offers from Non-Friends (16%), and Coercive Pressure to Use E-Cigarettes (10%). Hypothesized relationships between offer situations and e-cigarette use were partially confirmed, supporting the construct validity of the survey. This survey helps to fill the scientific and practice gap in measuring ecodevelopmental risk and protection for e-cigarette use and has implications for e-cigarette use prevention with rural, NHPI, and/or Indigenous youth populations.

A Cross-Sectional Study of Serum Levels of Several Vitamins in Healthy and Unhealthy Periodontal Conditions

Vitamins are examples of micronutrients, which are nutrients needed in very minute quantities. They're crucial to metabolism and keeping tissues working properly. The purpose of this study was to determine whether vitamin deficiencies are associated with an increased risk of periodontitis. There was a total of 110 participants: 55 with chronic periodontitis spread throughout the mouth and 55 periodontally healthy individuals. Clinical parameters that were assessed included: Clinical attachment loss (in millimetres) and gingival index (in millimetres). Vitamin B12, vitamin D, folate, as well as vitamin E levels in serum samples were measured. Also measured were Beta-carotene and Beta-cryptoxanthin levels. The acquired data was aggregated and analysed using statistical programmes. All periodontal status clinical measures in the periodontitis group were statistically significantly different from those in the healthy volunteers group (p < 0.0001). Vitamin A precursors Beta-carotene and Beta-cryptoxanthin, folate, D, vitamins B12, and E, and vitamin E were all significantly lower in the periodontitis group compared to the healthy volunteers, but the difference was only statistically significant for vitamins B12 as well as D (p < 0.05). Finally, we conclude that serum micronutrient levels, particularly those of Vitamin A, Vitamin B12, and Vitamin D, may be modifiable risk factors for periodontal disease. In addition to practicing good dental hygiene on a regular basis, eating a diet rich in the right kinds of vitamins may play a significant part in warding off periodontitis.

Confirmatory validation of a brief patient-reported outcome measure assessing psychological distress in caregivers of malignant mesothelioma patients: the Mesothelioma Psychological Distress Tool–Caregivers

ObjectiveThe diagnosis of malignant mesothelioma (MM) can be devastating for both patients and caregivers, who may experience intense suffering from a physical, psychological, and interpersonal perspective. Despite the extensive literature on caregiver distress, there is a lack of validated measures to provide evidence of psychological distress of caregivers of MM patients. Therefore, in a previous study we developed the Mesothelioma Psychological Distress Tool–Caregivers (MPDT-C) to evaluate the specific profile of psychological distress in this population. This paper describes the item selection, factor analysis, and psychometric evaluation of the revised MPDT-C.MethodsThe analyses of this work first aimed to confirm the previous factorial structure. In the case of nonfit, it aimed to find an alternative structure and causes of nonfit in the model. Examination of the fit of the factorial model was conducted using a Bayesian approach.ResultsThe final version of the MPDT-C is a 7-item self-report questionnaire consisting of one factor (Burden for the caregiver).ConclusionHaving a short self-report questionnaire to assess the psychological distress experienced by caregivers of MM patients has several advantages. First, it is suited to epidemiological studies where multiple variables and measures are involved. Second, it is easy to administer and does not take much time to complete. Therefore, the MPDT-C can also be administered in clinical contexts, perhaps when MM patients attend follow-up medical evaluation. Lastly, short measures are less affected by cognitive fatigue, which is very common in a long battery of tests and could affect response reliability.

No evidence hunting bait increases American black bear population growth in Maine, USA

AbstractAmerican black bear (Ursus americanus) populations are increasing throughout much of North America. Use of multiple harvest methods, including hunting over bait, is intended to increase harvest success rates to meet harvest and population management objectives. However, black bear population growth can be influenced by food availability, and some speculate the use of bait may inadvertently increase bear abundance through food resource supplementation. We collected hair from black bears captured from 2005–2019 and a selection of potential food items, including those used as bait from 3 study areas in Maine, USA, with different levels of human influence. We used stable isotope analysis of the black bear hair and food item samples to evaluate the contribution of different identified food groups to the diet of individual bears. We found no evidence that greater contribution of human food resources, including bait, increased the number of cubs per litter for reproductive females or that human foods comprised a greater part of the diet in years when natural food resources were less abundant. Approximately 69% of black bear harvest occurred over bait. We found the probability of reproductive‐age females to be harvested increased with average representation of human foods with high carbon enrichment (including bait) in their diet, but the relationship was weak, likely because of sampling constraints. Additionally, the probability of being harvested was greater in years when natural food resources were scarce. We conclude that bait is not available on the landscape in large enough amounts or for a sufficient amount of time in Maine to substantially influence female reproduction. Our results indicate hunting over bait is an effective tool in a state that is attempting to maintain a stable bear population via harvest, and dispels conjecture that hunting over bait may increase cub production and offset the intention of harvest.

Development and Validation of Dimensional Clinical Personality Inventory 2 (IDCP-2) Algorithms to Assess ICD-11 Personality Trait Domain Qualifiers.

With the advent of the new diagnostic model for personality disorders in the 11th revision of the International Classification of Diseases (ICD-11), researchers and practitioners in World Health Organization signatory countries are urged to implement it. This study aims to develop a brief, reliable, and valid scale for assessing maladaptive personality traits according to the ICD-11 model, using the item pool of the Dimensional Clinical Personality Inventory (IDCP-2). Quantitative and qualitative criteria for item selection were applied to a sample of 251 Brazilian adults. As a result, the 25 items (five items per factor) were selected, demonstrating promising evidence of validity based on the internal structure with a database of 1,659 Brazilian adults. In addition, we found good evidence of validity based on relationships with external variables, particularly those related to personality pathology, in a sample of 617 Brazilian adults. The implications of these findings are discussed.

Keabsahan Jual Beli Menggunakan Perbuatan (Bai‘ al-Mu‘āṭāh) dalam Tinjauan Kaidah Fikih

This research aims to find out and understand the validity of transactions without pronunciation, namely bai‘ al-mu‘āṭāh in reviewing the rules of fiqh. The type of research used is descriptive qualitative in the form of library research using a sociological approach to understand Islamic law, especially bai‘ al-mu‘āṭāh from a social perspective or community conditions. The results of this research show that bai‘ al-mu‘āṭāh is buying and selling carried out with certain movements or actions that show the agreement of both parties to the transaction. The validity of bai‘ al-mu‘āṭāh depends on the region and community conditions. In areas where transactions are commonly conducted through gestures without verbal expression, such as in almost all supermarkets in Indonesia where customers simply select items independently and pay at the cashier without any verbal exchange, bai‘ al-mu‘āṭāh is considered valid. However, in regions where transactions without verbal expression are uncommon, bai‘ al-mu‘āṭāh is not considered valid.

Tracing the Contours of Archival Silences: A Case Study of Critical Collection Building on the Rock Springs Massacre

ABSTRACTArchives can reinforce silences of marginalized communities, further erasing their stories and voices. This study aims to understand the contours of archival silences, focusing on experiences of Chinese people in the United States in the late 19th and early 20th centuries. We are building a digital archival collection that centers Chinese peoples' voices around the Rock Springs Massacre of 1885, an incident of racial violence that killed at least 28 Chinese people and displaced hundreds more. As we selected items, we wrote structured reflections to critically examine each item's content, source, presentation, arrangement and description in their original context, as well as any absences and silences that we encountered in the search and assessment process. Based on a praxis of radical empathy, ethics of care, and slow archives, we engaged with our positionalities, past experiences, professional training in Library and Information Sciences (LIS), and affective responses throughout the research process to reflect on how they shape our decisions and hesitations in item selection and contextualization. Three main themes emerged from a preliminary thematic analysis of our reflections: complexity of archival silences and silencing, challenges of inclusive representation, and problematizing and going beyond primary sources.

What can I do for my low back pain? The Work In Progress questionnaire!

There is growing evidence on Commitment Therapy for people with low back pain (LBP). A self-reported questionnaire is lacking which evaluates commitment by relying on the most recommended actions, the most important core outcome domains, and the most evidenced treatment options. To describe the development and psychometric validation of the Work In Progress (WIP) questionnaire. Development and psychometric validation of the WIP questionnaire in the context of people with LBP, as a means to evaluate Commitment. Outpatient facilities. People with LBP. The new instrument was created by item generation and selection. Face validity, appropriateness, acceptability and feasibility were investigated. Psychometric testing was carried out in a cross-sectional study and included: 1) exploratory factor analysis; 2) reliability by internal consistency (Cronbach's alpha) and test-retest measurement (Intra-class Correlation Coefficient, ICC<inf>2.1</inf>); and 3) construct validity by hypothesis testing the correlation of the WIP questionnaire with the Pain Catastrophizing Scale (PCS), the Oswestry Disability Index (ODI), and a pain intensity Numerical Rating Scale (NRS) (Pearson's r correlations). The WIP questionnaire was successfully developed based on international guidelines and the testing of face validity, appropriateness, acceptability and feasibility were satisfactory. The instrument was administered to 102 people with LBP (39 females, mean age of 49.7±14.6 years [range 20-80], pain median duration of 42.1 weeks [range 3-360]). Factor analysis revealed a two-factor 10-item solution (57% of explained variance). The internal consistency was good (α=0.70-85) and test-retest assessment was excellent (ICC<inf>2.1</inf>=0.91-94). Construct validity was good, as ≥75% of hypotheses were confirmed. The WIP questionnaire is a self-reported tool to evaluate commitment in persons with LBP showing satisfactory psychometric properties. It can be recommended for clinical and research purposes. This study adds original new data to the existing knowledge in the field of Commitment within the bio-psychosocial paradigm for disabled people. It is expected to contribute to the evaluative, clinical and rehabilitative approach of individuals with low back pain.

Most Common Symptomatic Adverse Reactions of Cancer Treatments From US Drug Labels (2015-2021) to Inform Selection of Patient-Reported Outcomes

ObjectivesIncorporating patient-reported outcomes (PROs) to assess symptomatic adverse events (AEs) in cancer clinical trials (CTs) is important to characterize treatment tolerability. Cancer therapies approved over the past decade have expanded the types of expected toxicities. To inform future symptomatic AE PRO item selection, we identified the most common symptomatic adverse reactions from recently approved products. MethodsWe reviewed approvals from 2015 to 2021 for lung, breast, and hematologic cancer indications. Using United States Prescribing Information safety data, we recorded symptomatic adverse reactions reported in ≥20% of patients in the experimental arm of CTs supporting approvals. We calculated the proportion of arms reporting each symptomatic adverse reaction. ResultsIn total, 130 experimental arms were included (lung = 30, breast = 10, hematologic = 90). For all cancer types, fatigue and diarrhea were reported in >50% of the arms. Nausea was reported in ≥50% of the arms for all except lung. Vomiting, decreased appetite, and alopecia, were reported in ≥50% of breast cancer arms. Rash, musculoskeletal pain, and cough were reported in >50% of leukemia/lymphoma arms. Cough was common (50%) in multiple myeloma arms. ConclusionsHeterogeneity in symptomatic adverse reactions across CTs supports the use of item libraries when building a PRO strategy to assess tolerability. Fatigue, diarrhea, and nausea were the most frequent symptomatic adverse reactions reported in contemporary cancer CTs and could provide a starting point when selecting PRO symptomatic AE items. Additional symptomatic AE PRO items should be selected based on the mechanism of action, early clinical data, published literature, and patient and clinician input.

청년창업가의 개인역량과 창업준비수준이 창업성과에 미치는 영향 요인 연구 : 창업컨설팅의 조절효과 중심으로

The purpose of this study was to verify the effect of young entrepreneurs' individual competency and start-up preparation level on start-up performance and the moderating effect on the reliability and satisfaction of start-up consulting. To this end, 190 surveys collected for young entrepreneurs living across the country were used for empirical analysis, and hierarchical regression analysis was conducted using SPSS v28.0. As a result of the analysis, first, it was found that item selection and start-up preparation period had a significant effect on start-up performance, which is a dependent variable among young entrepreneurs' individual competencies, and it was found that start-up funds did not significantly affect start-up performance among individual competencies in leadership competency, technological innovation competency, and start-up preparation level. Second, the moderating effect, consulting reliability and satisfaction, was found to partially control the individual competency and start-up performance of young entrepreneurs, and there was no moderating effect between the start-up preparation level and start-up performance of young entrepreneurs. Therefore, it can be confirmed that the individual competency and start-up preparation level of young entrepreneurs are important variables as they affect start-up performance. The results of these studies are hoped to be helpful to young entrepreneurs preparing for start-ups and policy makers for start-up support in customized policies for fostering young entrepreneurs.

Short and sweet: Comparing strategies for the reduction of questionnaires on self-criticism and social safeness while preserving construct validity.

Measuring psychological traits with standardised questionnaires is an essential component of clinical practice and research; however, patients and participants risk fatigue from overly long and repetitive measures. When developing the short form of a questionnaire, the most widely used method for selecting an item subset uses factor analysis loadings to identify the items most closely related to the psychological construct being measured. However, this approach will tend to select highly correlated, homogeneous items and might therefore restrict the breadth of the construct examined. In this study, we will present Yarkoni's genetic algorithm for scale reduction and compare it with the classical scale reduction method. The algorithm will be applied to the shortening of three instruments for measuring self-compassion and social safeness (two unidimensional measures and a three-factor measure). We evaluated the shortened scales using correlation with long-form scores, internal reliability and the change in the correlations observed with other related constructs. Findings suggested that the classical method preserves internal reliability, but Yarkoni's genetic algorithm better maintained correlations with other constructs. An additional qualitative assessment of item content showed that the latter method led to a more heterogeneous selection of items, better preserving the full complexity of the constructs being measured.

Effect of Differential Item Functioning on Computer Adaptive Testing Under Different Conditions.

This study provides an overview of the effect of differential item functioning (DIF) on measurement precision, test information function (TIF), and test effectiveness in computer adaptive tests (CATs). Simulated data for the study was produced and analyzed with the Rstudio. During the data generation process, item pool size, DIF type, DIF percentage, item selection method for CAT, and the test termination rules were considered changed conditions. Sample size and ability parameter distribution, Item Response Theory (IRT) model, DIF size, ability estimation method, test starting rule, and item usage frequency method regarding CAT conditions were considered fixed conditions. To examine the effect of DIF, measurement precision, TIF and test effectiveness were calculated. Results show DIF has negative effects on measurement precision, TIF, and test effectiveness. In particular, statistically significant effects of the percentage DIF items and DIF type are observed on measurement precision.
