 Processing Speed is Related to the General Psychopathology Factor in Youth | SpringerLink  https://ift.tt/efTkJjM The relationship between the  p  factor and cognition in youth has largely focused on general cognition (IQ) and executive functions (EF). Another cognitive construct, processing speed (PS), is dissociable from IQ and EF, but has received less research attention despite being related to many different mental health symptoms. The present sample included 795 youth, ages 11–16 from the Colorado Learning Disabilities Research Center (CLDRC) sample. Confirmatory factor analyses tested multiple  p  factor models, with the primary model being a second-order, multi-reporter  p  factor. We then tested the correlation between the  p  factor and a latent PS factor. There was a significant, negative correlation between the  p  factor and PS ( r (87) = -0.42,  p  < .001), indicating that slower processing speed is a...

 Model Specification Searches in Structural Equation Modeling Using Bee Swarm Optimization - Ulrich Schroeders, Florian Scharf, Gabriel Olaru, 2023  https://ift.tt/psGh3nm Metaheuristics are optimization algorithms that efficiently solve a variety of complex combinatorial problems. In psychological research, metaheuristics have been applied in short-scale construction and model specification search. In the present study, we propose a bee swarm optimization (BSO) algorithm to explore the structure underlying a psychological measurement instrument. The algorithm assigns items to an unknown number of nested factors in a confirmatory bifactor model, while simultaneously selecting items for the final scale. To achieve this, the algorithm follows the biological template of bees' foraging behavior: Scout bees explore new food sources, whereas onlooker bees search in the vicinity of previously explored, promising food sources. Analogously, scout bees in BSO introduce major changes...
