Psychopathological risk stability and change in a sample of mothers and preschool children before, during and after the peak of COVID-19 pandemic.

Numerous studies have found that the COVID-19 epidemic and the measures to stop it have had a substantial impact on the mental health of the general population. Nevertheless, the majority of this research only looked at the variations in the degree of psychopathological symptoms in individuals before and after the first wave of the pandemic. In a sample of N = 380 preschoolers and their mothers assessed through the Symptom Check-List/90-R and of the Child Behaviour Check-List, the present study aimed at exploring psychopathological risk in mothers and their offspring's dysregulation levels before (T1), during (T2) and after (T3) the peak of COVID-19 pandemic. Our main results showed that mothers' relational distress increased from T1 to T2 and then increased again from T2 to T3. Moreover, maternal aggressiveness, hostility, and anxiety scores significantly decreased from T1 to T2 but slightly increased from T2 to T3. In children, dysregulation levels increased from T1 to T2 but decreased from T2 to T3. Children of mothers with clinical scores at the SCL-90/R showed significantly higher dysregulation problems at T1, T2 and T3 than children of mothers with scores below the clinical threshold. This study adds to previous literature in that it evaluates stability or change in maternal and offspring scores not only in the pre-pandemic period and during the first wave of the pandemic, but it also considers the subsequent months, focusing on a broad range of maternal symptoms, rather than assessing depressive and anxiety symptoms as most of previous research did.
