Article Abstract
Background: One of the most important concepts within Cognitive Social Theory as framed by Bandura is the perceived self-efficacy; this concept became widespread in 1981 when Mathias Jerusalem and Ralf Schwarzer, using 10 items, established a one-dimensional and universal construct of this scale. The main purpose of this study is to show that the General Self-Efficacy Scale (GSE) is not a one-dimensional and universal construct, as is currently assumed.
Method: The data from 19,719 people from 26 countries were analyzed. In order to identify and understand invariance we applied seven multivariate statistical techniques.
Results: The findings suggest the existence of a multidimensional structure and differential item functioning by country. Insofar as there is differential item functioning by country and it is not possible to universalize it, and there are several items on the scale that statistically constitute additional factors. The results confirm that the self-efficacy construct is neither universal nor unidimensional.
Conclusions: A psychometric instrument must be valued and used with great care; the one in question is being used in a generalized way.

Multiple sclerosis (MS) is a chronic autoimmune disorder of the central nervous system (CNS) characterized by inflammatory demyelination and progressive neurodegeneration. Although current disease-modifying therapies modulate peripheral autoimmune responses, they are insufficient to fully prevent tissue specific neuroinflammation and long-term neuronal and oligodendrocyte loss. Growing evidence implicates various regulated cell death (RCD) pathways, including apoptosis, necroptosis, pyroptosis, and ferroptosis, not only as downstream consequences of chronic inflammation, but also as active drivers of demyelination, axonal injury, and glial dysfunction in MS.

Decades of antibiotic misuse have spurred an antimicrobial resistance crisis, creating an urgent demand for alternative treatment options. Although phototherapy has therapeutic potential, the efficacy of the most advanced photosensitizers (PS) is essentially limited by aggregation-induced quenching, which significantly reduces their therapeutic effect. To address these challenges, we developed a cationic metallocovalent organic framework (CRuP-COF) via a solvent-mediated dual-reaction synthesis strategy.

Background: Advanced cancer impacts the lives of both patients and their family caregivers. They often experience substantial declines in quality of life and physical, emotional, and spiritual distress that generate significant unmet psychosocial care needs. These effects are interrelated.

Risk-based firearm laws are a firearm injury prevention strategy. However, evidence for their efficacy in reducing firearm injury is mixed. There is agreement that the magnitude of their effect depends on implementation and efficacy would improve with better implementation.
