Measurement invariance of the higher-order model of Preschool Anxiety Scale (PAS) across child age, gender, parental anxiety, and pandemic period in England by Creswell, C, Reardon, T, Spence, S, Zhou, S

“…The Preschool Anxiety Scale (PAS) is a parent-report scale measuring young children’s anxiety symptoms involving five specific anxiety symptoms (separation anxiety, physical injury fears, social phobia, obsessive-compulsive disorder, generalised anxiety) that load on a higher-order factor representing general anxiety shared by all specific anxiety symptom subtypes. Although the PAS has been widely used to assess anxiety symptoms in young children, few studies have tested its measurement invariance for group comparisons. …”

The multicomponent exchange of metals between magmatic fluids and silicate melts by Gion, AM, Gaillard, F
