Gender-based differential item functioning in measures of eating pathology.

International Journal of Eating Disorders, 2019
OBJECTIVE Eating disorder (ED) symptoms are common and impairing in males, despite their perception as "female" disorders. As existing self-report symptom measures were developed and primarily validated in women, there is a need to establish the utility ...

Social context prevents heat hormetic effects against mutagens during fish development

FEBS Letters, EarlyView.
This study shows that sublethal heat stress protects fish embryos against ultraviolet radiation, a concept known as ‘hormesis’. However, chemical stress transmission between fish embryos negates this protective effect. By providing evidence for the mechanistic molecular basis of heat stress hormesis and interindividual stress communication, this study ...

Differential Item Functioning: Beyond validity evidence based on internal structure

Psicothema, 2018
Background: In the latest release of the Standards for Educational and Psychological Testing, Differential Item Functioning (DIF) is considered as validity evidence based on internal structure.

Interaction vesicles as emerging mediators of host‐pathogen molecular crosstalk and their implications for infection dynamics

FEBS Letters, EarlyView.
Interaction extracellular vesicles (iEVs) are hybrid vesicles formed through host‐pathogen communication. They facilitate immune evasion, transfer pathogens' molecules, increase host cell uptake, and enhance virulence. This Perspective article illustrates the multifunctional roles of iEVs and highlights their emerging relevance in infection dynamics ...

Exploring differential item functioning in the SF-36 by demographic, clinical, psychological and social factors in an osteoarthritis population [PDF]

, 2013
The SF-36 is a very commonly used generic measure of health outcome in osteoarthritis (OA). An important, but frequently overlooked, aspect of validating health outcome measures is to establish if items work in the same way across subgroup of a ...

Autophagy in cancer and protein conformational disorders

FEBS Letters, EarlyView.
Autophagy plays a crucial role in numerous biological processes, including protein and organelle quality control, development, immunity, and metabolism. Hence, dysregulation or mutations in autophagy‐related genes have been implicated in a wide range of human diseases.

A stepwise emergence of evolution in the RNA world

FEBS Letters, EarlyView.
How did biological evolution emerge from chemical reactions? This perspective proposes a gradual scenario of self‐organization among RNA molecules, where catalytic feedback on random mixtures plays the central role. Short oligomers cross‐ligate, and self‐assembly enables heritable variations. An event of template‐externalization marks the transition to

Age and Sex Effects in Anchoring Vignette Studies: Methodological and Empirical Contributions

Survey Research Methods, 2013
Anchoring vignettes are an increasingly popular tool for identifying and correcting for group differences in use of subjective ordered response categories. However, existing techniques to maximize response consistency (use of the same standards for self-
