A study led by Yuanyuan Li of Beijing Normal University has found that psychological resilience may shield children from certain brain-network changes associated with abuse, but not neglect. The research, conducted with 94 schoolchildren aged 10 to 14 from rural China, suggests resilience could buffer some neurobiological effects of adversity, though its protection against neglect remains unclear.
Psychological resilience describes the ability to adapt and continue functioning during difficult circumstances. It is not necessarily a fixed personality trait, and researchers increasingly view resilience as a capacity that can change with support, relationships and intervention.
The researchers aimed to determine whether resilience altered the relationship between different forms of adversity and the way brain networks communicate. They differentiated abuse—physical and emotional—from neglect, which involves a lack of emotional, physical or material support, noting that these experiences can have distinct effects.
The team, based in Beijing, studied 94 children from rural China, including 48 boys and 46 girls, aged between 10 and 14. The sample was described as marked by poverty and by the experience of being “left behind,” a term used for children whose parents have migrated to cities for work.
Participants completed questionnaires on childhood adversity, resilience, depression, anxiety and physical symptoms. Abuse was measured as a combination of physical and emotional abuse, while neglect combined physical and emotional neglect. Resilience was assessed by asking how well children cope with challenges, including whether they feel able to handle whatever comes their way.
Immediately after, the children underwent a resting-state functional MRI scan to track how activity within and between brain networks fluctuates when at rest, followed by a second assessment six months later of depression, anxiety and physical symptoms.
Two children were excluded for excessive movement during scanning, leaving 92 participants with an average age of about 11.8 years for the main analysis. The researchers examined connections within and between seven large-scale brain networks, with key focus on the limbic network, the ventral attention network (also known as the salience network), and the somatomotor network.
Across the full sample, neither abuse nor neglect was linked to the brain-network measures once age, sex, perceived socioeconomic status and the other form of adversity were accounted for. The associations with abuse emerged only when resilience levels were taken into account.
Among children with lower resilience, greater exposure to abuse was associated with stronger connectivity between the limbic network and the somatomotor network. This pattern helped explain the link between abuse and more physical complaints, such as headaches, stomachaches and tiredness, as well as higher depression scores at the initial assessment.
In these children, greater abuse also correlated with stronger connectivity between the limbic and ventral attention networks. Both patterns helped explain higher anxiety levels six months later, even after controlling for initial anxiety. These associations were absent in children with average or higher resilience.
However, the results did not show the same protective effect for neglect. Neglect was not significantly associated with the brain-network measures, regardless of resilience levels, although those reporting more neglect tended to report more depressive symptoms at both the start of the study and six months later. This ran counter to the researchers’ expectation that resilience would offset effects of both forms of adversity.
The authors suggested that neglect may be more chronic and widespread in the study population, potentially making resilience alone insufficient to offset its impact. They argued that addressing neglect could require alleviating underlying deprivation, for example by providing more material resources and supporting more responsive caregiving.
Li and colleagues concluded: “Our findings reveal that psychological resilience specifically shields against the neurotoxic effects of abuse by modulating networks involved in emotion regulation, salience, and sensorimotor processing.”
Limitations noted include measuring adversity and brain connectivity at the same time, which prevents establishing causality. Children also reported their past adversity, which may introduce recall bias, and sexual abuse was not assessed due to sensitivity in Chinese elementary schools. The sample was relatively small for detecting subtle effects, and the link between brain connectivity and later anxiety was not statistically significant when a stricter motion-exclusion criterion was applied during scanning.
