Three new corrections for standardized person-fit statistics for tests with polytomous items.

Recent years have seen a growing interest in the development of person-fit statistics for tests with polytomous items. Some of the most popular person-fit statistics for such tests belong to the class of standardized person-fit statistics, , that is assumed to have a standard normal null distribution. However, this distribution only holds when (a) the true ability parameter is known and (b) an infinite number of items are available. In practice, both conditions are violated, and the quality of person-fit results is expected to deteriorate. In this paper, we propose three new corrections for that simultaneously account for the use of an estimated ability parameter and the use of a finite number of items. The three new corrections are direct extensions of those that were developed by Gorney etal. (Psychometrika, 2024, https://doi.org/10.1007/s11336-024-09960-x) for tests with only dichotomous items. Our simulation study reveals that the three new corrections tend to outperform not only the original statistic but also an existing correction for proposed by Sinharay (Psychometrika, 2016, 81, 992). Therefore, the new corrections appear to be promising tools for assessing person fit in tests with polytomous items.

Cardiorespiratory fitness and working memory in persons with traumatic brain injury: a cross-sectional analysis

ABSTRACT Introduction Cognitive impairment is a highly impactful consequence of traumatic brain injury (TBI) and there are limited evidence-based treatment practices to combat these impairments. Evidence from other populations suggest that aerobic exercise training (AET) is beneficial for a variety of cognitive deficits, but the research in persons with TBI to date is equivocal. One potential reason is the heterogeneity of exercise prescriptions and outcome measures. This stems from the fact that studies have not been designed based on previous data supporting a specific AET prescription to target a cognitive domain. The primary purpose of this cross-sectional analysis was to examine the relationship between cardiorespiratory fitness (CRF), as a cross-sectional surrogate of AET, and cognition in persons with TBI to inform future research. Methods Cross-sectional analysis was conducted on baseline data of persons with TBI who completed neuropsychological assessments to evaluate several cognitive domains and a cardiopulmonary exercise test (CPET) to measure CRF. Based on the normal distribution of an outcome, Pearson’s r or Spearman’s ρ was calculated to measure the relationship between CRF and cognition. Results Data were analyzed for all participants who demonstrated valid CPETs (n = 21 of 29). Based on the cycle ergometer-based norms of CRF, males in this sample were in the 69th percentile and females in this sample were in the 56th percentile, with high variability across individuals. Higher CRF, as measured by peak power output (Wpeak), was significantly associated with greater working memory (ρ = 0.465, p = 0.017), even after post-hoc corrections. Conclusions These data suggest average and highly variable CRF in persons with TBI of all severity and support cycle ergometry-based CPET testing in this population. Further, these data provide support for future research applying AET to target working memory and possibly other executive functions in persons with TBI. This research is a small step toward large-scale randomized controlled trials that can directly impact clinical care to treat cognitive symptoms post-TBI.

Interest–Major Fit predicts study satisfaction and/or achievement? Comparing different ways of assessment

ABSTRACT Prospective students and higher educational institutions often share the matching goal to ensure an optimal fit between the demands of study programs and the student profile. A strong personal fit is meant to facilitate long-term study satisfaction and optimal performance. However, to truly understand the impact of such a fit, we must first reach a consensus on how to measure the construct. At this point, researchers and higher education practitioners are debating different avenues in this regard: In the past, the fit has often been measured by assessing vocational interests tied to potential occupations that are attainable through a study program (Interest–Vocation Fit). Here, we argue that more specific measures tailored to the respective major (Interest–Major Fit) have more predictive power. We compare the two operationalizations of fit as predictors of performance and study satisfaction in a sample of 455 German university students who participated in a longitudinal survey study. We found that the different measures of personal fit were associated with subsequent university GPA and study satisfaction. Moreover, we found that Interest–Major Fit was more closely associated with these outcome measures compared to Interest–Vocation Fit. We also found that only Interest–Major Fit has incremental predictive power for study satisfaction beyond high school GPA. These findings should be helpful to researchers interested in the intricacies of measuring fit and higher education practitioners aiming to develop diagnostic tools alike. Such tools may in turn assist prospective students in finding the major that caters best to their personal needs and interests.

Association of Physical Fitness with Leisure Time Physical Activity in Individuals with Spinal Cord Injury

Abstract Background: Physical fitness of persons with spinal cord injury (SCI) is related to their upper limb strength and range of motion. A change in these factors may impact their participation in physical fitness, and consequently leisure time activities. The objective of the study was to examine an association of physical fitness with leisure time physical activity (LTPA) in people with SCI. Materials and Methods: This was a cross-sectional observational study conducted among 30 male and female participants with SCI. Physical fitness and LTPA were assessed using a 6-min push test and physical activity recall assessment for people with SCI, respectively. Spearman’s Rank correlation coefficient was used to estimate the correlation between physical fitness and LTPA in persons with SCI. Results: The mean age of the participants was 33.6 ± 7.73) years. This study found a positive weak to no correlation between physical fitness and LTPA in individuals with SCI (r s = 0.1008) that was statistically nonsignificant (P > 0.596). In this study, 28 (93.33%) participants had good physical fitness, and 19 (63.33%) participants performed LTPA for 20 min or more in a day, whereas 11 (36.67%) performed less than 20 min per day. Conclusion: Though most of the participants had good physical fitness, they performed only exercise-based activities such as walking with orthosis, pushups exercises, and resistance training exercises for upper limb muscles in their leisure time. They did not participate in LTPA such as sports, gardening, swimming, and other recreational activities. Furthermore, studies can be done to understand the perception of physiotherapists and SCI individuals toward the participation of LTPAs.

SUBSTANTIATION OF THE PROFESSIONAL STANDARD OF "PERSONAL FITNESS TRAINER" IN UKRAINE

Professional staff is needed for the effective functioning of health fitness. There are no professional standards for fitness staff in Ukraine, so there is no single standardized approach to determining the list of job functions, general and special competencies, the required knowledge, skills and practical abilities. The purpose of the study is to substantiate and develop a professional standard of "Personal Fitness Trainer" taking into account international experience. Methods: analysis and generalization of scientific and methodical literature, pedagogical observation, functional analysis, documentary method, method of expert evaluations, methods of mathematical statistics. Results. The development of a professional standard for "Personal Fitness Trainer" was based on regulatory acts and the algorithm formed for the health fitness system. There have been identified 60 necessary labor actions which ensure the performance of 9 labor functions of a fitness trainer. The professional standard takes into account the needs of employers, consumer requirements and will be the basis for the industry standard of higher education in the relevant specialty. Conclusions. The developed professional standard for "Personal fitness trainer" is relevant, complies with regulatory acts and established algorithm, adapted to the system of fitness. The expediency of developing a professional standard "Personal fitness trainer" was based on the study of the actual state and prospects of application of fitness staff. The professional standard provides requirements for the content and quality of professional activity; list of general competencies; requirements for the level of qualification, medical contraindications to work, work experience, level of education of a fitness trainer; a list of labor functions and labor actions and the necessary knowledge, skills and abilities; list of subjects and means of work and definition of professional competencies, etc. The professional standard "Personal fitness trainer" should be the basis for the industry standard of higher education in the relevant specialty.

Rasch validation of the revised body awareness rating questionnaire (BARQ-R) in adults with and without musculoskeletal pain

BackgroundThe Revised Body Awareness Rating Questionnaire (BARQ-R) is a self-report measure of body awareness. First aim: evaluate the structural validity of BARQ-R with Rasch analysis in community-dwelling Americans with and without musculoskeletal pain. Subaim: validate a Rasch analysis of BARQ-R done in Norwegian adults with musculoskeletal pain, through a secondary analysis in our sample of Americans with musculoskeletal pain.MethodsBARQ-R has 12 items with scores ranging from 0 (completely disagree) to 3 (completely agree), with higher total scores reflecting lower degrees of body awareness. Through Rasch analysis, we evaluated unidimensionality, item hierarchy, and structural validity with item and person fit, targeting, person separation reliability (PSR), local item dependence (LID), differential item functioning (DIF), and principal components analysis of residuals (PCAR).ResultsWe recruited 623 adults with and without musculoskeletal pain (average age = 50.27 ± 17.25 years). After rescoring 1 item and deleting 3 items, the 9-item Rasch-based BARQ-R had no misfitting items, the hierarchical ordering of the items followed clinical expectations, 3 (0.48%) misfitting persons, person mean location: -0.62 ± 1.03 logits (max -0.53, min 0.72 logits), minimal floor effect (1.93%) and ceiling effect (0.48%), no DIF, and PSR = 0.72. LID was found in 5 item pairs. The PCAR’s eigenvalue was 2.18. The secondary Rasch analysis in 152 adults with musculoskeletal pain (average age = 52.26 ± 16.13 years), demonstrated that, after rescoring 2 items, BARQ-R had no misfitting items and only 2 (1.32%) misfitting persons, good targeting (person mean location: -0.36 ± 0.88 logits), minimal floor effect (0.01%), no ceiling effect (0.00%), and PSR = 0.75. LID was found in 6 item pairs. The PCAR’s eigenvalue was 2.47.ConclusionsBARQ-R had good item and person fit. PSR with items covering a limited logit range suggests that differing levels of body awareness are measured with only modest precision. Adding and revising items to cover a wider range of body awareness and to better address concepts of internal body awareness and body movements would improve BARQ-R’s utility. Further analyses are needed before BARQ-R’s use for research or in the clinic. In addition, future BARQ-R Rasch validation is needed in other populations with body awareness deficits, such as stroke or spinal cord injury.

Examining the Psychometric Impact of Targeted and Random Double‐Scoring in Mixed‐Format Assessments

AbstractDouble‐scoring constructed‐response items is a common but costly practice in mixed‐format assessments. This study explored the impacts of Targeted Double‐Scoring (TDS) and random double‐scoring procedures on the quality of psychometric outcomes, including student achievement estimates, person fit, and student classifications under various conditions that reflect operational performance assessments. Using a simulation study, our results suggest no notable advantages for TDS over the random double‐scoring approach across various psychometric outcomes, regardless of conditions related to student misfit, rater misfit, and rater severity. This study holds significant implications for mixed‐format assessments, offering insights into a comprehensive evaluation of double‐scoring methods. We recommend that researchers consider these findings when considering among double‐scoring procedures.

Development and validation of the 5-Dimension Comprehensive Assessment Scale (5DCAS) for assessing physical function and health in axial spondyloarthritis.

To describe the development and validation of a novel patient reported scale, which is a comprehensive assessment of the physical function and health specific for patients with axial spondyloarthritis (axSpA). This is a multiphase, mixed methods study. Based on opinion collection and discussions of multidisciplinary consensus meetings and patients, an initial item pool covering all of the ranges of functioning was generated. The item optimization, model fit, response category functioning, differential item functioning, reliability, structure validity, and unidimensionality were tested by confirmatory factor analysis and Rasch measurement theory framework. After the consensus meeting and the two rounds of surveys in patients with axSpA, the initial pool of 135 items was reduced to 25 items formed in five dimensions, which exhibited preferable item reliability, item fit, and person fit to the Rasch model. The Five-Dimensional Comprehensive Assessment Scale (5DCAS) had the best reliability and validity (Kaiser-Meyer-Olkin was 0.919, and the standardized Cronbach's α coefficient was 0.932). The final version of 5DCAS had good unidimensionality, and the Person Separation Index ranged from 0.77 to 0.85. 5DCAS significantly correlated with ASAS-HI, SF-36, BASFI, and disease activity with p values of < 0.001. 5DCAS is a novel patient-reported outcome specific to axSpA, and it forms five dimensions providing a linear sum score of 25 items. 5DCAS comprehensively and significantly represents the physical function and health status of patients with axSpA, although its performance needs further validation in future clinical practices. Key Points • The primary goal in the management of axial spondyloarthritis is to maximize health-related quality of life. Except for the current instruments of ASAS-HI, BASFI, or SF-36, the heterogeneous clinical symptoms and rapid updated treat-to-target concept require a new instrument which can comprehensive and significant evaluate the changes of physical function and health-related quality of life due to disease. • 5DCAS is a novel patient-reported outcome specific to axSpA, and it forms five dimensions providing a linear sum score of 25 items, which contained aspect of pain involvement, spine mobility, global body performance and activity, social participation and environment, and mental health. All of the items were set to a 4-point semantic rating scale measuring severity, frequency, or interference from score 0 to 3. Total 5DCAS score ranges from 0 to 75; higher scores represented greater symptom burden and worse physical function. • 5DCAS is a comprehensive, multidisciplinary, and convenient disease outcome measurement specific for axSpA. It provides a new evaluation instrument in clinical trial and treat-to-target clinical remission for patients and physicians, and also provides a sensitive and accurate assessment standard for optimized health benefits.

Rasch Analysis of the Chinese Version of the Nociception Coma Scale-Revised in Patients with Prolonged Disorders of Consciousness.

The aim of this study was to analyze the Chinese version of the Nociception Coma Scale-Revised in patients with prolonged disorders of consciousness within the framework of Rasch modeling, including investigating the invariance of total scores across different etiologies of disorders of consciousness. Prospective psychometric study. Patients with prolonged disorders of consciousness from the Rehabilitation and Neurology units in hospital. None. The Nociception Coma Scale-Revised was undertaken by trained raters and the Coma Recovery Scale-Revised was used to assess patients' consciousness. The psychometric properties within the Rasch model including item-person targeting, reliability and separation, item fit, unidimensionality, and differential item functioning were assessed. 84 patients with prolonged disorders of consciousness (mean age 53 years; mean injury 5 months; 42 with Minimally Conscious State and 42 with Unresponsive Wakefulness Syndrome) of 252 observations were enrolled in the study. Through the procedure of repeated assessment and differential item function, a lower item bias Rasch set was purified. The Rasch model assumptions were examined and met, with item reliability and validity meeting the recommended threshold. The Chinese version of the Nociception Coma Scale-Revised demonstrated unidimensionality, good reliability and separation, and good item fit, but dissatisfied person fit and item-person targeting. The verbal subscale showed a notable discrepancy between person responses and the difficulty of the items, suggesting limited clinical significance.

Rasch Measurement Theory (RMT) Analyses of the Huntington's Disease Everyday Functioning (Hi-DEF) to Evaluate Item Fit and Performance.

The Huntington's Disease (HD) Everyday Functioning (Hi-DEF) is a new patient-reported outcome (PRO) instrument designed to measure the impact of cognitive impairment on daily functioning in the early stages of HD. To assess the measurement properties and finalize item content of the Hi-DEF. A cross-sectional, observational psychometric validation study was conducted among individuals with early stages of HD at 9 US centers of excellence. Rasch Measurement Theory (RMT) analysis of the initial draft version of the Hi-DEF (47 items) and subscales (i.e., 'Home', 'At work', 'Driving', and 'Communication') was conducted to examine measurement properties including sample-to-scale targeting, suitability of response scale (ordering of response thresholds), scale cohesiveness (item fit), local independence, and person fit. 151 participants (mean age 47 years (SD 12), 59% female) were included. Seven items were removed based on dependency and item fit. The remaining 40-item version of the Hi-DEF demonstrated good measurement properties. Across the four subscales, targeting ranged from 49-70% (72% full scale), reliability ascertained by person separation index ranged from 0.53-0.87 (0.92 full scale), response scales were ordered for 25-100% of items (75% full scale), 0-12% items displayed misfit (2% full scale), and 0-1% (2% full scale) item pairs displayed dependency. Our study supports the psychometric integrity of the Hi-DEF as a reliable and valid new PRO instrument designed to assess the impact of cognitive impairment on daily functioning in the early stages of HD. Future work will evaluate the external validity and utility in clinical trial applications.

Total, Between-, and Within-Item Attribute Person Fit Analysis Using Mokken Scaling Techniques: An Exploratory Nonparametric Approach to Person Fit

The purpose of this study was to consider how researchers can incorporate item attributes into nonparametric person fit analysis for the purpose of providing additional insight into person fit beyond what is available using typical total-scale person fit approaches. Inspired by parametric person fit statistics that consider patterns of residuals at the total-scale, between-item-attribute, and within-item-attribute levels, we proposed simple adaptations to standard Mokken Scale Analysis (MSA) person fit analysis techniques to reflect these three levels of person fit analysis. We demonstrated the technique using a secondary analysis of survey data related to learning motivation and considered how the results may be interpreted in an affective assessment context. We used a simple exploratory simulation study to consider the techniques under a wider range of conditions. Overall, the results suggested that it is possible to incorporate item attributes into MSA person fit analysis at the total-scale, between-item-attribute, and within-item attribute levels, and that each set of analyses provides a unique perspective on person fit.

Asymptotically Correct Person Fit z-Statistics For the Rasch Testlet Model.

A well-known person fit statistic in the item response theory (IRT) literature is the statistic (Drasgow et al. in Br J Math Stat Psychol 38(1):67-86, 1985). Snijders (Psychometrika 66(3):331-342, 2001) derived , which is the asymptotically correct version of when the ability parameter is estimated. However, both statistics and other extensions later developed concern either only the unidimensional IRT models or multidimensional models that require a joint estimate of latent traits across all the dimensions. Considering a marginalized maximum likelihood ability estimator, this paper proposes and , which are extensions of and , respectively, for the Rasch testlet model. The computation of relies on several extensions of the Lord-Wingersky algorithm (1984) that are additional contributions of this paper. Simulation results show that has close-to-nominal Type I error rates and satisfactory power for detecting aberrant responses. For unidimensional models, and reduce to and , respectively, and therefore allows for the evaluation of person fit with a wider range of IRT models. A real data application is presented to show the utility of the proposed statistics for a test with an underlying structure that consists of both the traditional unidimensional component and the Rasch testlet component.

Psychotherapists' outcome expectations: How are they established?

Therapists' outcome expectations influence the psychotherapy process and outcomes, but little is known about the factors influencing their development. This study explored therapists' experiences with establishing outcome expectations for their patients. The participants were 35 therapists from a public mental health setting, who were interviewed in five different focus groups. Interviews were transcribed and analyzed using thematic analysis. Three themes and 10 subthemes were identified. In Theme 1 (understanding the problem), participants' expectations were influenced by (a) their patients' diagnoses and the diagnostic process, (b) their perceptions of the complexity of the presenting problem, (c) how stable the patients' symptoms and situations were, and (d) whether they experienced familiarity with the patient or the patients' situation. In Theme 2 (the patient's openness to change), participants' expectations were influenced by (a) the patient's stated reason for seeking treatment, (b) the patient's conceptualization of their problem/situation, and (c) their perception of the patient's willingness to invest in the treatment. In Theme 3 (the fit between the therapist and patient), the participants discussed the factors that influenced whether they felt they were a good fit for working with an individual patient and how this perception of personal and professional fit influenced their expectations. We identify several ways that therapists' situational factors and their recognition of the patient through their own past experiences can influence their expectations.

Measurement properties of the Swedish version of the anterior cruciate ligament return to sport after injury scale (ACL-RSI): A Rasch analysis.

This study aimed to investigate the measurement properties, according to the Rasch Measurement Theory, of the anterior cruciate ligament return to sport after injury scale (ACL-RSI) in patients treated with ACL reconstruction in Sweden. ACL-RSI responses from 1065 patients treated with ACL reconstruction were extracted from a rehabilitation-specific registry. Rasch analyses were performed on ACL-RSI item response data using the RUMM2030plus software. The analyses focused on targeting (person-item threshold distribution), item hierarchy, response category thresholds, overall and individual item and person fit, differential item functioning (DIF), unidimensionality and reliability. The ACL-RSI had compromised fit to the Rasch model, including DIF and malfunctioning response categories. Several items correlate with each other and the presumptions to aggregate item responses into one single score were not met. When accounting for local dependency, the measurement properties of the ACL-RSI improved in terms of model fit and DIF and unidimensionality were supported. The ACL-RSI was found to have signs of multidimensionality and local dependency, that is, the answers to one item are influenced by the answers to other items. As such, researchers should be careful when using the ACL-RSI as one single score to evaluate patients treated with ACL reconstruction, unless local dependency is accounted for in the scoring process. Level III.

Initial evaluation of measurement properties of the Work Environment Impact Questionnaire (WEIQ) - using Rasch analysis

BackgroundTo provide both preventive and rehabilitative conditions in a workplace, one must understand how employees experience work demands. Such an understanding can be obtained from each individual with valid and quality-assured questionnaires. The Work Environment Impact Questionnaire (WEIQ) is a new questionnaire for measuring employees’ self-perceived work ability in relation to their specific workplace environment. The purpose of this study was to assess the measurement properties in terms of construct validity of the WEIQ.MethodsA cross-sectional survey study was conducted with 288 respondents from three different workplaces involving assisted living personnel, vocational rehabilitation personnel and personnel at a research institute. The measurement properties of the WEIQ were assessed according to Rasch Measurement Theory (RMT), including assessment of item-to-sample targeting, threshold ordering, item fit statistics, unidimensionality and reliability.ResultsItem fit, i.e., fit residuals, item characteristic curves (ICC) and chi square values, were all satisfactory, and no disordered thresholds were present after collapsing the lowest response categories. However, issues with local dependent (LD) item correlations was present in 7.6% cases, four items showed statistically significant differential item functioning (DIF), where 11% of the respondents had person fit residuals outside the recommended range of ± 2.5 and the t-test for unidimensionality did not meet the criterion of 5%. Scale-to-sample targeting and reliability (0.92) were good. LD could be resolved with testlets and at the same time maintaining fit and improving dimensionality, but then the reliability decreased to 0.82.ConclusionsThis study provides an initial validation of the WEIQ to be used for assessing employees’ self-perceived work ability. Most measurement properties were acceptable, but further exploration of LD, DIF and unidimensionality in additional work settings and with larger sample sizes is warranted.Trial registrationNot applicable.

Psychometric evaluation of the pictorial scale of perceived movement skill competence in Chinese children: An item response theory analysis.

This study aimed to investigate the psychometric characteristics of the Pictorial Scale of Perceived Movement Skill Competence (PMSC) in Chinese children, utilizing the principles of item response theory (IRT). A total of 284 children (147 boys), aged 4-10years (Mage = 7.39, SD = 2.18), from four schools were recruited for testing, adhering to the principle of random sampling. The Rasch model was applied to evaluate the rating scale validity, local independence, scale dimensionality, person and item fit statistics, and differential item functioning (DIF). (1) The rating scale validity was confirmed by the monotonically increasing trend in both average item difficulty measures and Andrich thresholds. (2) However, the observation that standardized residual correlations for all items remained below 0.3 unequivocally confirmed the presence of local independence among the variables. (3) The scale's dimensions were substantiated, with Rasch measures explaining 40.6% of total variance, exceeding the 40% threshold. Additionally, the first contrast had an eigenvalue of 1.8 and explained 8.80% of the variance, both exceeding the minimum 3:1 ratio. Consequently, the unidimensionality assumption of the item was supported. (4) Person and item fit statistics indicated requisite reliability and separation, with all achieving suitable infit and outfit measures, and point-biserial correlations exceeding 0.55. (5) Regarding gender DIF, it was observed that the majority of items did not exhibit statistically significant gender DIF effects (p > 0.05) except item 8 (Bounce a ball, t = -2.74, p < 0.01, DIF = -0.51). Rasch analysis revealed that the instrument exhibited strong scale validity among Chinese children, adhering to the Rasch model's unidimensionality and local independence principles, with robust person and item reliability and separation. All items demonstrated a good fit. Additionally, the significant gender difference in item 8 (Bounce a ball) warrants further consideration. In conclusion, PMSC is suitable for assessing the PMSC of Chinese children.

Resolving and Re-Scoring Constructed Response Items in Mixed-Format Assessments: An Exploration of Three Approaches

ABSTRACT We explored three approaches to resolving or re-scoring constructed-response items in mixed-format assessments: rater agreement, person fit, and targeted double scoring (TDS). We used a simulation study to consider how the three approaches impact the psychometric properties of student achievement estimates, with an emphasis on person fit. We found that although TDS is not specifically designed to identify discrepant or misfitting score profiles, this approach can improve person fit for students who are also within a critical range of achievement. Our findings also suggest that TDS alone is not sufficient to provide a comprehensive picture of measurement quality because it does not directly consider person fit. We suggest that researchers and practitioners consider combining TDS with other approaches to score resolution. We consider the implications of our findings for research and practice.

A Study of Talent Acquisition Lifecycle – A Review on Pyxidia Techlab

The research paper explores into the use of digital tools in talent acquisition, focusing on sourcing, screening, and shortlisting applicants. In today's digital age, recruitment has adopted a variety of digital tools, including video job descriptions (JDs) and resumes. These technologies make it possible to examine candidates efficiently, focusing on communication skills, personality, and cultural fit before inviting them to interviews. Keyword utilization speeds up applicant selection based on qualifications and experience. Following the initial screening, AI-driven questionnaires assess candidates' job-related skills and knowledge. This ensures that only the most competent candidates make it to HR and stakeholder interviews. These in-person or virtual interviews test interpersonal skills and problem-solving ability. Following completion, successful applicants go through onboarding, which includes team introductions and resource allocation for effective role performance. Talent acquisition has been altered by digital technologies like as video JDs, resumes, AI questions, and virtual interviews. This saves time and resources while also increasing productivity, employee satisfaction, and organizational success. Keywords— Talent Acquisition, Methodology, Stages, Challenges, E-Recruitment.
