اثر واسطه رشد شناختی در بسط نگرانی کودکان

The present study investigated how developmentally determined cognitive mechanisms, holding theoretical links to the worry process, mediate the relationship between Age and Worry Elaboration in children. Sixty-four children aged 3–7 (M = 5.58, SD = 1.28) were presented with a Conservation of Liquid task assessing their Cognitive Development (specifically Concrete Operational Skills), a false-belief task to measure possession of Belief–Desire Theory of Mind, and a task measuring the ability to acknowledge multiple possibilities. The ability to elaborate on potential negative outcomes was assessed using a Worry Elaboration task. Mediation analysis revealed that all three variables significantly mediated the relationship between Age and Worry Elaboration. A multiple mediation model is presented in which Concrete Operational Skills, Belief–Desire Theory of Mind and Multiple Possibilities understanding mediate the relationship between Age and Worry Elaboration.
