Relationship Between Adverse Childhood Experiences and Depressive Symptoms Among Nursing Students: Serial Mediation Effects of Family Communication, Perceived Stress, and the Moderating Effect of Self-Efficacy
This study of 932 Chinese nursing students reveals that adverse childhood experiences predict depressive symptoms primarily through a serial mediation pathway involving impaired family communication and heightened perceived stress, while self-efficacy unexpectedly showed a weak moderating effect that slightly strengthened the stress-depression link.

Depression is a heavy burden that affects millions of people worldwide, often making daily life feel overwhelming and draining. While the condition can strike anyone, those training to become nurses face a unique set of pressures. They must master difficult academic coursework while simultaneously learning to care for sick patients, a role that demands intense emotional labor and resilience. For these students, the roots of their current struggles may stretch back much further than their university years. Scientists have long known that adverse childhood experiences—harmful events like abuse, neglect, or living in a chaotic home before age eighteen—leave a lasting mark on mental health. Yet, the exact path from those early wounds to the depression many students feel today remains a puzzle. Specifically, researchers have wondered how the way a young adult communicates with their family, the stress they feel in their daily lives, and their own belief in their ability to handle challenges might weave together to shape this outcome.
A team of researchers set out to untangle these connections by looking at a large group of nursing students across China. They gathered data from 932 students aged 18 to 35, representing 196 different universities. The goal was not just to see if bad childhood experiences were linked to current sadness, but to map the journey between them. The researchers asked the students to reflect on their pasts, their current family relationships, how stressed they felt, and how confident they were in their own abilities. They then used statistical methods to trace how these factors influenced one another, treating the university each student attended as a distinct community to ensure the results were accurate.
The study confirmed what many suspected: students who reported more adverse childhood experiences were indeed more likely to report severe depressive symptoms. However, the research went deeper to explain why. It found that the link between a difficult past and current depression was not a straight line but a chain of events. The most powerful bridge in this chain was perceived stress. Students with more difficult childhoods tended to feel a higher level of stress in their current lives, and this feeling of being overwhelmed was strongly tied to their depressive symptoms. In fact, stress accounted for the largest portion of the indirect connection between the past and the present.
Family communication played a supporting, yet specific, role in this story. The researchers found that students with adverse childhood histories often reported poorer communication with their families. This lack of clear, supportive connection did not directly cause depression on its own in this model. Instead, it acted as a precursor to stress. When family communication was weak, it seemed to contribute to higher levels of perceived stress, which then led to depression. This suggests that for these students, the quality of their current family interactions matters most because it influences how much stress they feel, rather than acting as a direct cause of their sadness.
The researchers also investigated whether a student's belief in their own capabilities, known as self-efficacy, could act as a shield. They wondered if students who felt more confident in their ability to handle tasks would be less affected by stress. Surprisingly, the data showed a different, though small, pattern. The link between stress and depression was actually slightly stronger for students with higher self-efficacy. This finding was unexpected, as confidence is usually seen as a protective factor. The researchers noted that this result was small and might be influenced by the specific way confidence was measured or by other unmeasured factors. They cautioned that this does not mean confidence is harmful, but rather that it did not provide the expected buffer against stress in this specific group of students.
Ultimately, the study paints a picture where the weight of a difficult childhood is carried forward primarily through the lens of current stress. While family communication sets the stage by influencing how much stress a student feels, it is the feeling of being overwhelmed that most directly connects the past to the present struggle with depression. The findings suggest that helping nursing students manage their stress levels could be a vital step in supporting their mental health, especially for those who have faced adversity early in life. The researchers emphasize that while these patterns are clear in the data, they are based on a single snapshot in time, and future studies will be needed to confirm how these relationships change as students move through their training and careers.
