Abstract: Objectives To demonstrate the use of Rasch analysis by assessing the appropriateness of utilizing the Hospital Anxiety and Depression Scale (HADS) total score (HADS-14) as a measure of psychological distress.
Design Cross-sectional, using Rasch analysis.
Methods The HADS was administered to 296 patients attending an out-patient musculoskeletal rehabilitation program. Rasch analysis was conducted using RUMM2020 software to assess the overall fit of the model, the response scale used, individual item fit, differential item functioning (DIF) and person separation.
Results Rasch analysis supported the viability of the HADS-14 as a measure of psychological distress. It showed good person separation, little disordering of the thresholds and no evidence of DIF. One anxiety item (item 11) showed some misfit to the model. The residuals patterned into the two subscales (anxiety and depression), but the person estimate derived from these two subscales was not statistically different to that derived from all items taken together, supporting the assumption of unidimensionality. A cut-point of 12 on the HADS-14 identified all cases that were classified as both anxious and depressed on the original individual HADS subscales.
Conclusions The results of Rasch analysis support the use of the HADS-14 as a global measure of psychological distress. The study demonstrates the usefulness of Rasch analysis in assessing the psychometric properties of a scale and suggests that further use of this technique to assess the HADS-14 in other clinical groups is warranted.

Longitudinal validity and reliability of the Myeloma Patient Outcome Scale (MyPOS) was established using traditional, generalizability and Rasch psychometric methods
Christina Ramsenthaler,Wei Gao,Richard J. Siegert,Richard J. Siegert,Steve Schey,Poly M. Edmonds,Irene J Higginson +6 more
TL;DR: The MyPOS demonstrated good longitudinal measurement properties, with potential areas for revision being the Healthcare Support subscale and the rating scale, and the new psychometric approaches should be used for testing validity of monitoring in clinical settings.
Decision Making for Individual Investors: A Measurement of Latent Difficulties
TL;DR: In this paper, the authors adopt the Rasch model to analyze latent and unobservable factors that cause difficulties in investment participation for investors in Taiwan and identify how investors' confidence and information gathering ability affect their decision making by using the investment theory on crystallized and fluid intelligences.

An investigation into the effects of topic and background knowledge of topic on second language speaking performance assessment in language proficiency interviews

TL;DR: In this article, the authors explored the extent to which the two variables of topic and background knowledge of topic have an effect on spoken performance in language proficiency interviews and found that participants' different levels of background knowledge were shown to have a consistent, systematic and statistically significant effect on performance with low-level background knowledge posing the highest level of challenge for test takers and vice versa.
