China’s rapid economic transformation, characterized by large-scale rural-to-urban labor migration and accelerated urbanization over the past few decades, has profoundly reshaped traditional family structures. At the center of this social restructuring is a massive shift in child-rearing dynamics: grandparents have increasingly stepped into the roles of primary, sole custodial, or shared co-resident caregivers for millions of children. A newly published perspective article in Frontiers in Psychology (Volume 17, September 2026) synthesizes the complex psychological implications of these evolving caregiving arrangements, shedding light on the critical balance between grandparenting quality, intergenerational coparenting, and the mental health outcomes of vulnerable children. The study, authored by researchers Guangfu Yuan and Aihua Su, emphasizes that the mental health landscape of Chinese children is deeply tied to the structural configuration of their households. Rather than treating family arrangements as uniform, the research distinguishes between distinct domestic environments: skip-generation households where children are left behind by migrating parents, and three-generation urban households where grandparents and parents share daily childcare duties. As policy-makers and clinical practitioners grapple with rising rates of pediatric anxiety, depression, and behavioral difficulties, this comprehensive synthesis advocates for a paradigm shift toward multigenerational clinical assessments. Background Context: The Rise of Grandparent-Led Caregiving in Modern China The large-scale movement of the workforce from rural agricultural provinces to booming urban centers has created a distinct demographic phenomenon: millions of rural left-behind children (LBC). Nationally representative monitoring data indicate that approximately 69.7 million rural children reside in villages while one or both parents migrate for long-term urban employment. Furthermore, studies show that these left-behind minors face significantly constrained socioeconomic resources and are substantially more vulnerable to poverty than their peers living with both parents. However, researchers note that left-behind children are not a homogenous group. They exist within different caregiving configurations that dictate their daily psychological reality. Children whose both parents have migrated typically find themselves in a dyadic grandparent-child unit where the grandparent functions as the sole custodial caregiver. Conversely, children with only one migrated parent remain embedded in a triadic system where a resident parent and a grandparent share coparenting responsibilities. Simultaneously, in urban centers, roughly 66.5% of grandparents are actively involved in raising their grandchildren within three-generation households. This arrangement creates what sociologists and psychologists term "intergenerational coparenting"—the joint exercise of child-rearing responsibilities between parents and grandparents. Whether driven by economic necessity in rural villages or the demands of dual-income careers in cities, the intensification of grandparental involvement has become a defining characteristic of contemporary Chinese family life. Risks and Vulnerabilities: Internalizing and Externalizing Challenges While grandparents provide essential stability in the absence of biological parents, psychological research demonstrates that the structural arrangement of grandparental care is not inherently protective. A systematic review and meta-analysis of 38 studies encompassing 344,860 children reveals that children primarily cared for by grandparents exhibit modestly higher rates of internalizing problems (such as anxiety, withdrawal, and depression), externalizing problems (such as aggression and conduct difficulties), and lower socioemotional well-being compared to children raised strictly by both parents. Additional studies focusing on rural left-behind children highlight elevated prevalences of social anxiety, internet addiction, and self-harm behaviors, particularly among young girls and adolescents. Clinical surveys in southwest China have identified clinically diagnosed depressive disorders in a notable percentage of left-behind minors, with emotional symptoms linked directly to the disruption of the parent-child bond. However, the authors emphasize that the mere presence of a grandparent does not dictate psychological outcomes; rather, the quality of grandparenting is the decisive factor. Warm, responsive, and behaviorally engaged grandparents act as a powerful resilience buffer, promoting prosocial behavior and shielding children from the psychological toll of parental absence. Conversely, overindulgent, inconsistent, or highly overprotective grandparenting styles are closely correlated with heightened emotional and behavioral difficulties in children. The Dynamics of Intergenerational Coparenting In households where parents remain present—such as urban three-generation families—the dynamics of intergenerational coparenting introduce another layer of psychological influence. Guided by theoretical frameworks such as Feinberg’s coparenting model and family systems theory, researchers have identified four core components of shared child-rearing: agreement on principles, division of labor, mutual support or undermining, and joint management of family interactions. When generational values clash, coparenting conflict frequently emerges as a principal risk factor. Large-scale meta-analyses demonstrate that coparenting friction, competitiveness, and triangulation are significantly associated with increased internalizing and externalizing problems in children. Furthermore, caregiver mental health plays a profound mediating role. Actor-partner interdependence models show that depressive symptoms in either parents or grandparents indirectly predict harsher disciplinary practices and reduced supportiveness toward children, transmitted through the perceived quality of the coparenting relationship. Cultural frameworks deeply influence these dynamics. In China, Confucian norms of filial piety dictate that adult children defer to older generations. This cultural expectation can blur the lines of authority, generating role ambiguity and power struggles over child-rearing practices. Latent profile analyses indicate that discordant coparenting relationships correlate with severe stress, depressive symptoms, and poor sleep quality among primary caregivers, particularly mothers. Resilience Pathways and Strength-Based Approaches Despite documented risk pathways, the literature highlights robust protective mechanisms that can buffer children against adversity. Family systems theory suggests that positive dynamics within one family subsystem can compensate for stress in another. Key resilience pathways include: Engaged Grandparenting: Active and balanced grandparental involvement reduces parenting stress for mothers and strengthens overall family cohesion, fostering a stable emotional environment for child development. Coparenting Harmony: Harmonious collaboration between parents and grandparents correlates strongly with positive psychosocial outcomes for caregivers and significantly attenuates the detrimental impact of occasional family conflicts on child behavior. Quality Parent-Child Communication: For left-behind children, maintaining regular, emotionally attuned communication with migrated parents via mobile technology serves as a vital regulatory anchor, sustaining emotional security across physical distances. Clinical and Nursing Implications for Practice The findings synthesized in the Frontiers in Psychology perspective article carry direct implications for pediatric psychiatry, psychology, and nursing practice. The authors argue that mental health professionals working with Chinese children must adopt a multigenerational assessment lens. Traditional clinical protocols that focus exclusively on the parent-child dyad often fail to capture the complex intergenerational dynamics operating in Chinese households. Clinicians are advised to routinely integrate screening instruments that evaluate coparenting relationship quality, grandparental involvement, and caregiver mental health. For nursing practitioners operating in community health centers and pediatric clinics, delivering family-centered care models that engage parents and grandparents simultaneously offers a highly effective intervention strategy. Evidence-based parenting programs, such as culturally adapted variants of the Triple P (Positive Parenting Program) and its grandparent-specific modules, have shown success in reducing child behavioral problems and enhancing caregiver self-efficacy in Chinese populations. By respecting cultural values like filial piety while helping families negotiate clear, low-conflict caregiving roles, practitioners can better support the mental health and long-term resilience of vulnerable children. Future Research Directions As family structures continue to evolve across China’s diverse regional and socioeconomic landscapes, researchers call for more longitudinal studies and randomized controlled trials to establish causal pathways. Future investigations must also aim to bridge the current gap between left-behind child research and urban coparenting studies, incorporating digital and remote forms of parental involvement to better understand how modern families navigate care across physical divides. Through harmonized research and culturally sensitive clinical interventions, practitioners can better safeguard the psychological well-being of the next generation.
