La qualità del sonno come mediatore tra stile di vita e engagement cognitivo e agentico degli studenti: Un approccio di modellizzazione a equazioni strutturali
Parole chiave:
Engagement scolastico, Qualità del sonno, Adolescenza, Stile di vita, Uso della tecnologia, Attività fisicaAbstract
Lo studio esamina la relazione tra stili di vita e qualità del sonno, nonché la conseguente associazione con i livelli di engagement scolastico. La ricerca ha coinvolto un campione di 1.065 adolescenti italiani frequentanti la scuola secondaria; i dati raccolti sono stati analizzati mediante un modello di equazioni strutturali che stima gli effetti diretti e indiretti di quattro variabili esogene (consumo serale di alimenti ricchi di triptofano, attività fisica vigorosa, presenza di dispositivi elettronici nella camera da letto e il loro spegnimento prima del riposo notturno) sull’engagement cognitivo e agentico, ponendo la qualità del sonno quale variabile mediatrice. La bontà di adattamento del modello è risultata eccellente (CFI = 0.975, TLI = 0.980, RMSEA = 0.034 [90% CI 0.031-0.038], SRMR = .050). L’attività fisica vigorosa e il numero di dispositivi spenti prima di coricarsi sono emersi quali predittori significativi della qualità del sonno, la quale media la relazione tra tali fattori e l’engagement scolastico. Al contrario, l’alimentazione serale e la mera quantità di dispositivi presenti nella camera da letto non sono risultate significative.
