Summary: This study developed a condition-specific caregiver proxy-report measure for Duchenne Muscular Dystrophy (DMD) utilizing item banks from the PROMIS system, aiming to understand the impact of DMD on caregivers. The study sample included 521 DMD caregivers and showed strong psychometric characteristics in most domains. Future research will focus on assessing the responsiveness and validity of the measure over time and its comparison to DMD patient self-report.

Summary: By using measurement results and data comparison from PROMIS Anxiety and Depression item banks, the researchers found that the Dutch and US populations have similar levels of anxiety and depression symptoms, allowing for comparisons using standardized parameters. The Dutch reference values provide an important tool for healthcare professionals and researchers.

Summary: Item response theory (IRT) is often implemented in the human sciences using R packages like brms and the probabilistic programming language Stan. These tools allow for the specification and fitting of Bayesian IRT models with various response distributions and parameter configurations, making it easy to extract posterior distributions and evaluate model fit.

Summary: Item Response Theory (IRT) is a mathematical framework that explains the relationship between a test taker's observable response on a test item and their latent ability. IRT models and statistical methods are commonly used in educational and psychological research. Estimating the IRT model parameters is a crucial step in applying IRT to test data.

Summary: The study aimed to test the psychometric properties of an Italian custom four-item Short Form of the PROMIS Anxiety item bank in a cohort of outpatients with IMIDs. Results showed that the instrument has excellent reliability and validity, making it suitable for clinical populations such as IMID patients.

Summary: This study investigates the suitability of monotonic polynomials (MP) for PRO data and finds that the MP model has better overall fit and higher information for physical functioning compared to the GRM model, although some items may not fit well. Simulations also support the performance of the MP model.

Summary: This study compared the performance of the PROMIS(R) anxiety short form 6a and the Generalized Anxiety Disorder 7-item scale in a sample of U.S. military veterans, finding that the former performed better in terms of item difficulty estimates and distribution of response categories. However, further validation is needed in larger, more diverse samples.

Summary: The study found that unless true change in the PROMIS physical function and emotional distress scales is substantial, classical test theory estimates of significant individual change are much more optimistic than estimates of change based on item response theory.

Summary: This study investigated the functioning of PROMIS-GH across different clinical settings, patient ages, and medical complexities, finding no differential item functioning (DIF) within the GMH and GPH domains across age groups, medical complexity, or clinical environment. Items assessing GMH and GPH within the PROMIS-GH were found to function comparably across treatment setting, age category, and medical comorbidities.

Summary: This paper investigates the performance of item response theory based on distance criteria rather than likelihood criteria. A reconstructed item response matrix using maximum likelihood estimates is introduced, and the distance between the observed and estimated matrices is measured using the Frobenius matrix norm. The comparison of the distance between the observed and low-rank matrices helps evaluate the performance of the estimated item response matrix. The study finds that the predictive ability of item response theory is high enough when using test data, as the distance between the approximated low-rank matrix and observed item response matrix is approximately equal to or slightly less than the distance between the estimated item response matrix and observed item response matrix.

Summary: Psychological wellbeing plays a vital role in our ability to cope with and thrive in the challenges of life. The measurement of psychological wellbeing is important for identifying mental illness and promoting health. This study examined the psychometric properties of the 18-item Swedish version of Ryff's Psychological Wellbeing Scale and found that a five-factor model provided a better fit than the original six-factor model. The scale demonstrated good internal consistency and concurrent validity, and measurement precision was similar across gender. Some items may need revision to improve accuracy.

Summary: Ensemble learning combines multiple algorithms or models to improve predictive performance and is used in various fields. This study introduces the use of Item Response Theory (IRT), a model used in educational psychometrics, to construct an unsupervised anomaly detection ensemble. The effectiveness of the IRT ensemble is demonstrated and shown to outperform other ensemble techniques, even with low correlation values among the anomaly detection methods.
