Paradoxical Association Between Campus Connectedness and Delusion-Like Experiences Among Chinese College Students: A Chained Mediation

The mental well-being of college students remains a critical concern, with psychotic-like experiences, particularly delusion-like symptoms, emerging as a significant area of research. A recent study published in Frontiers in Psychology sheds light on the complex interplay between campus connectedness, insomnia, depression, and these delusion-like experiences among Chinese university students. The findings suggest that while a strong sense of belonging to the campus community may offer protective benefits, its relationship with delusion-like experiences is not straightforward and is significantly influenced by factors such as sleep disturbances and depressive symptoms.

Key Findings and Their Significance

The research, which surveyed 1,048 college students in China, revealed a nuanced picture. Initially, a negative correlation was observed between campus connectedness and delusion-like experiences, aligning with the expectation that a supportive campus environment might deter such symptoms. However, a deeper analysis using structural equation modeling introduced two crucial mediators: insomnia and depression.

When insomnia and depression were accounted for, the direct protective effect of campus connectedness on delusion-like experiences diminished. More strikingly, the direct association between campus connectedness and delusion-like experiences shifted from negative to positive, indicating a suppression-like pattern. This suggests that while overall campus connectedness might be beneficial, specific pathways involving sleep and mood disorders complicate this relationship.

Understanding Delusion-Like Experiences in College Populations

Delusion-like experiences, defined as subclinical manifestations of delusional thinking such as ideas of reference, persecutory beliefs, or feelings of being controlled, are more common than previously thought among young adults. Studies have indicated that a substantial percentage of college students report experiencing such phenomena, with prevalence rates varying based on the criteria used. For instance, one study found that nearly 40% of Chinese college students reported at least one delusion-like experience in the past month, while another indicated that over 59% endorsed at least one such item. These experiences, though not meeting the diagnostic threshold for psychosis, are associated with an increased risk of developing more severe mental health conditions.

The college environment itself plays a significant role in shaping student mental health. For many students, particularly in countries like China where campus management can be semi-closed, the university campus is a primary social ecosystem. Factors like teacher support, peer relationships, and a general sense of belonging—collectively termed campus connectedness—are understood to contribute to overall well-being and adjustment. Previous research has consistently linked positive campus connectedness to better mental health outcomes, including reduced stress and improved psychological resilience.

The Mediating Roles of Insomnia and Depression

The study hypothesized that campus connectedness might influence delusion-like experiences indirectly through proximal risk factors like insomnia and depression. This hypothesis is well-supported by existing literature. Lower campus connectedness has been associated with poorer sleep quality and increased depressive symptoms. Conversely, both insomnia and depression are known correlates of delusion-like experiences. The high prevalence of sleep problems and depressive symptoms among college students globally further underscores the importance of investigating these factors.

The research explored two potential pathways:

1. Independent Mediation: Campus connectedness influences insomnia, which in turn influences delusion-like experiences. Similarly, campus connectedness influences depression, which then influences delusion-like experiences.
2. Chained Mediation: Campus connectedness influences insomnia, which then influences depression, and finally, depression influences delusion-like experiences.

The results confirmed significant indirect associations through both independent and chained mediation pathways, suggesting that campus connectedness can influence delusion-like experiences by affecting sleep and mood.

The Suppression-Like Effect: A Paradoxical Finding

The most intriguing finding is the "suppression-like" effect observed in the direct path between campus connectedness and delusion-like experiences. After accounting for the mediating roles of insomnia and depression, the initially negative association between campus connectedness and delusion-like experiences became positive. This phenomenon, where a mediator can statistically "suppress" or alter the sign of the direct effect between an independent variable and a dependent variable, suggests a more complex dynamic than a simple protective model.

One interpretation of this suppression effect is that while general campus connectedness might be beneficial, specific aspects or subgroups within a connected campus could be indirectly contributing to delusion-like experiences through their impact on insomnia and depression. For instance, intense academic pressure within a highly connected cohort might exacerbate sleep problems and depressive symptoms, which then manifest as delusion-like experiences. Alternatively, the presence of these mediators might be so strong that they effectively "explain away" the direct negative association, leaving a positive direct effect that needs careful interpretation.

Methodology and Sample

The study employed structural equation modeling (SEM) to analyze data collected from 1,048 college students in China. Participants completed an online questionnaire assessing campus connectedness, insomnia, depression, and delusion-like experiences. The instruments used were validated scales, including the Campus Connectedness Scale (CCS), the Youth Self-Report Insomnia Scale (YSIS), items developed by Dhir et al. for depressive symptoms, and items by Sun et al. for delusion-like experiences.

The sample comprised students aged 17-26 years, with a majority being first-year undergraduate students. Demographically, the sample was predominantly female (67.5%) and concentrated in households with relatively lower monthly incomes, reflecting a specific socioeconomic profile of Chinese college students. The data were collected between February and March 2022.

Implications for Mental Health Interventions

The findings carry significant implications for the development of mental health interventions in university settings. While fostering campus connectedness remains a valuable strategy, it should be complemented by targeted interventions addressing insomnia and depression.

• Holistic Approach to Campus Connectedness: Universities should aim to create an environment that promotes genuine connection and support, but also recognizes and mitigates potential stressors that can arise even within connected communities. This might involve fostering a sense of belonging that doesn’t equate to undue pressure or conformity.
• Early Detection and Intervention for Sleep and Mood Disorders: Proactive screening and support for students experiencing insomnia and depression are crucial. These conditions appear to be key pathways through which campus-related factors influence delusion-like experiences.
• Tailored Support Services: Interventions should be tailored to address the specific needs of students, recognizing that the relationship between campus life and mental health is multifaceted. This could involve a combination of individual therapy, group support, and psychoeducational programs.

Limitations and Future Directions

The researchers acknowledge several limitations of the study. The cross-sectional design prevents definitive conclusions about causality and temporal ordering. The observed suppression-like effect warrants further investigation, potentially through longitudinal studies that can track changes over time. The reliance on self-report measures, while efficient, is subject to biases such as recall and social desirability. Furthermore, the specific demographic profile of the sample may limit the generalizability of the findings to other student populations or cultural contexts.

Future research could benefit from:

• Longitudinal Designs: To establish temporal relationships between campus connectedness, insomnia, depression, and delusion-like experiences.
• Multimethod Assessments: Incorporating objective measures (e.g., sleep trackers, clinician assessments) alongside self-reports.
• Diverse Samples: Including students from various academic disciplines, socioeconomic backgrounds, and geographical regions.
• Exploration of Specific Campus Features: Investigating how particular aspects of the campus environment (e.g., academic rigor, social activities, administrative policies) interact with individual factors.

Conclusion

The study provides compelling evidence that the relationship between campus connectedness and delusion-like experiences among Chinese college students is complex and mediated by insomnia and depression. The observed suppression-like effect highlights that simply increasing campus connectedness may not uniformly reduce delusion-like symptoms. Instead, a more nuanced approach is required, focusing on mitigating sleep and mood disturbances within the broader context of fostering a supportive campus environment. By addressing these interconnected factors, universities can better support the mental well-being of their students and potentially reduce the incidence of psychotic-like experiences.
