Exploring the relationship between mental health status and life events in children and adolescents: the role of mediating factors

Background: The mental health status of children and adolescents is significantly influenced by negative life events, yet there is a lack of comprehensive analysis on mediating factors. This study aims to examine the relationship between negative life events and symptoms of anxiety and depression in children and adolescents, as well as to identify potential mediating factors.

Methods: In May 2022, cluster-randomized sampling was used to select 8041 primary, middle, and high school students in Zhaoqing City, Guangdong Province, for the final analysis. The Adolescent Life Events Scale, Self-Rating Anxiety Scale, and Self-Rating Depression Scale were employed to assess negative life events, anxiety symptoms, and depressive symptoms, respectively. Pearson correlation analysis and linear regression analysis were utilized to identify risk factors, and the Bootstrap method was applied for mediation analysis.

Results: The study revealed that 80.52% of children and adolescents experienced negative life events, with 23.38% reporting anxiety symptoms and 42.57% reporting depressive symptoms. Significant positive correlations were observed between negative life events and anxiety symptoms (r = 0.32, p < 0.001), as well as depressive symptoms (r = 0.44, p < 0.001). Mediation analysis further demonstrated that anxiety and depressive symptoms acted as mutual mediators in the relationship between negative life events and each other.

Conclusions: This study underscores the complex interplay between anxiety, depression, and negative life events in children and adolescents. These findings can inform strategies to help mitigate the emotional impact of negative life events, enhance mental health, and provide a scientific basis for developing effective interventions.

1 Introduction

Mental health problems are highly prevalent among children and adolescents, with the most common issues being negative emotional states such as depressive and anxiety symptoms (1). Negative life events in these age groups are significant risk factors for mental health issues, as demonstrated by various studies exploring the correlation between mental health problems and negative life events (2, 3). According to DeLongis et al., major life events act as distal influences on physical and mental health, while daily life events serve as proximal influencing factors (4). Large-scale public health crises, such as the COVID-19 pandemic, have further intensified anxiety and depressive symptoms in children and adolescents due to widespread social and lifestyle disruptions, profoundly affecting their overall well-being (5). Moreover, chronic anxiety and depression during these formative years are strong predictors of persistent mental health challenges in adulthood (6). These findings underscore the critical importance of prioritizing mental health interventions for children and adolescents.

Negative life events are significant contributors to the development of anxiety and depression in children and adolescents (7). Research consistently shows a strong association between negative life events and the onset of these mental health issues (8). Such events often serve as direct triggers for depressive symptoms (9). For example, children and adolescents who encounter negative life events—such as challenges related to relationships, academic pressures, health issues, and adjustment difficulties—are at an increased risk of developing severe depressive symptoms. Furthermore, depressive symptoms themselves can predict the occurrence of additional negative life events (10, 11), creating a vicious cycle where initial depressive symptoms amplify the likelihood of subsequent negative life events, which in turn worsen the symptoms (12). Studies have highlighted this bidirectional relationship: the frequency and severity of negative life events correlate with higher levels of depressive symptoms, and vice versa (13, 14), suggesting a pattern of mutual causation. Negative life events are also closely linked to anxiety disorders (15), with anxiety symptoms frequently emerging in children and adolescents following such experiences (16). While the mechanisms underlying this association are less well-studied, several investigations suggest that life events often precede the onset of anxiety disorders (17).

Most existing studies focus on the relationship between negative life events and psychological problems in children and adolescents (18–20), while analysis of potential mediating factors is clearly insufficient. As a result, the relationship between negative life events and depressive and anxiety symptoms in healthy children and adolescents remains underexplored. To better understand how anxiety, depression, and life events are interconnected, the fields of behavioral medicine and psychology often involve constructing multiple mediating variables to clarify the mechanisms through which independent variables influence dependent ones (21). This approach helps reduce estimation errors that may arise when mediating factors are overlooked. Therefore, this study hypothesizes that there is a reciprocal influence between anxiety symptoms, depressive symptoms, and negative life events, with potential underlying mediating factors. The aim of this study is to explore the interactions between depressive and anxiety symptoms and negative life events in children and adolescents, as well as the mediating factors involved, in order to provide a more comprehensive foundation for both theoretical understanding and practical interventions, ultimately contributing to the improvement of mental health outcomes in this population.

2 Materials and methods

2.1 Participants and procedures

The cross-sectional investigation method was used to study the primary, middle and high school students in Zhaoqing city, Guangdong province. The whole random sampling method was adopted, and the questionnaire was distributed uniformly by the investigator to guide the students to complete the survey. A total of 8,245 questionnaires were distributed, of which 204 were excluded due to incomplete information, multiple or missing selections, or other invalid questionnaires, with a valid response rate of 97.5%. They were all between 7 and 20 years old.

2.2 Sociodemographic information

Socio-demographic characteristics, including age, sex, and educational level, were collected by self-designed questionnaires.

2.3 Measures

2.3.1 Negative life events

The Adolescent Life Events Scale was used to assess the physical and mental health of adolescents based on their physiological and psychological characteristics and social roles in Chinese society (22). This scale has been validated through extensive testing (23, 24), demonstrating robust reliability and validity. The scale comprises 27 items across six factors: interpersonal relationships, academic stress, punishment, loss, health adaptation, and others. Responses are scored on a 5-point Likert scale: “1” indicates no impact, “2” mild impact, “3” moderate impact, “4” severe impact, and “5” extreme impact. Higher scores reflect greater stress experienced by the individual.

2.3.2 Anxiety symptoms

The Self-Rating Anxiety Scale (SAS) was developed to assess anxiety status of adolescents (25). This scale consists of 20 items, each rated on a 4-point scale: “1” indicates no or very little time, “2” indicates some of the time, “3” indicates most of the time, and “4” indicates most or all the time. It evaluates the subjective feelings of respondents over the past week, with higher scores indicating a higher tendency toward anxiety.

2.3.3 Depressive symptoms

The Self-Rating Depression Scale (SDS) was used to evaluate the depressive status of adolescents (26). This scale includes 20 items, rated on a 4-point scale: “1” represents no or very little time, “2” represents a small amount of time, “3” represents a considerable amount of time, and “4” represents most or all the time. It assesses the respondents’ subjective feelings over the past week, with higher scores indicating a greater tendency toward depression.

2.4 Statistical analysis

Data were analyzed using SPSS 26.0. Measurement data conforming to a normal distribution were expressed as mean ± standard deviation (M ± SD). Comparisons between groups were conducted using the t-test. The variance inflation factor (VIF) was used to assess multicollinearity among independent variables, with VIF > 5 indicating significant multicollinearity. Spearman correlation analysis was conducted to examine the relationships among life events, anxiety, and depression in children and adolescents. Multiple linear regression was used to analyze these relationships further. The Bootstrap method was employed to test the significance of the mediating effects among life events, anxiety, and depression. A total of 5000 bootstrap samples were drawn, and the 95% bootstrap confidence interval (CI) was calculated. A 95% CI that did not include zero indicated a significant mediating effect (27). A p-value < 0.05 was considered statistically significant (two-tailed).

3.3 Results of the correlation analysis

According to Table 3, depressive symptoms were found to be positively correlated with anxiety symptoms (r = 0.67, p < 0.001) and adolescent life events (r = 0.32, p < 0.001). Conversely, it was negatively correlated with age (r = -0.08, p < 0.001), gender (r = -0.08, p < 0.001), and education level (r = -0.07, p < 0.001). Anxiety symptoms exhibited a positive correlation with adolescent life events (r = 0.44, p < 0.001) and a negative correlation with gender (r = -0.09, p < 0.001), with no statistically significant correlation with age and education level. Adolescent life events were positively correlated with age (r = 0.07, p < 0.001) and education level (r = 0.11, p < 0.001), but negatively correlated with gender (r = -0.06, p < 0.001). There was also a positive correlation between age and education level (r = 0.73, p < 0.001), and no statistically significant correlation between gender and education level.

3.5 Results of the bootstrap analysis of mediation effects

To gain a deeper understanding of mediating effects, this study assessed the significance of each indirect effect by applying the bootstrap procedure, which would involve plotting 5000 bootstrap samples and calculating 95% CI. The 95% CI for each pathway excluded zero, indicating significant overall, direct, and indirect effects.

Table 5 shows that the overall effect of negative life events on depressive symptoms was 0.24 (SE = 0.007, 95% CI = 0.22-0.25, t = 33.21, p < 0.001). The direct effect was 0.03, accounting for 12.5% (SE = 0.006, 95% CI = 0.01-0.04, t = 4.58, p < 0.001). The indirect effect was 0.21, accounting for 87.5% (SE = 0.006, 95% CI = 0.02-0.22). Figure 1 visually illustrates this mediating relationship, reinforcing the importance of anxiety symptoms in the connection between negative life events and depressive symptoms.

4 Discussion

To the best of our knowledge, this study is the first to investigate the relationship between negative life events and psychological problems in children and adolescents, along with their potential mediators. The key findings of this study are as follows: (1) The prevalence of negative life events was 80.52%, while the prevalence of anxiety symptoms and depressive symptoms was 23.38% and 42.57%, respectively. (2) Anxiety symptoms and depressive symptoms were positively correlated with negative life events among children and adolescents; (3) Most importantly, this study found that, among children and adolescents, negative life events, anxiety symptoms, and depressive symptoms each served as mediators in the relationships between the other two factors.

The current study highlights a high prevalence of negative life events (80.52%), anxiety symptoms (23.38%), and depressive symptoms (42.57%) among children and adolescents, findings that align with existing research (28). Prior studies have consistently demonstrated the significant role of negative life events as risk factors for mental health problems in this population. For instance, Zou et al. reported that negative life events are closely associated with increased anxiety and depressive symptoms, particularly in interpersonal and adaptation-related stressors (29). Similarly, Spinhoven et al. observed that childhood adversities, including emotional neglect, contribute substantially to the development of depression and anxiety disorders across the lifespan (30). Moreover, during the COVID-19 pandemic, the prevalence of anxiety and depression was exacerbated by increased exposure to negative life events, as highlighted in Taheri et al., who emphasized the interaction between environmental stressors and genetic predispositions in shaping mental health outcomes (31, 32). These findings underscore the urgency of implementing targeted interventions to mitigate the psychological impact of adverse life events among children and adolescents.

Recent findings demonstrate a significant correlation between negative life events and anxiety and depression in children and adolescents, consistent with prior research. Negative life events such as family conflict, academic pressure, and interpersonal challenges elevate stress levels, impair coping mechanisms, and increase susceptibility to mental health issues like anxiety and depression (29). Adolescents, particularly those prone to rumination, are more vulnerable, with severe depressive symptoms often linked to dwelling on negative experiences (33, 34). The COVID-19 pandemic intensified the impact of negative life events, with increased isolation, disrupted schooling, and parental stress contributing to heightened anxiety and depressive symptoms (35, 36). Vulnerable groups, including those from low socioeconomic backgrounds, were disproportionately affected (37). The interaction between negative life events and mental health outcomes reflects a complex, nonlinear relationship, mediated by psychological resilience, family climate, and coping styles.

Additionally, one of the key findings of this study is the reciprocal mediating relationship among anxiety symptoms, depressive symptoms, and negative life events, demonstrating a bidirectional connection between these factors. This indicates that depressive symptoms play a crucial role in linking negative life events to anxiety symptoms (38). As external stressors, negative life events indirectly influence depressive levels by triggering changes in anxiety symptoms (39, 40). Similarly, these life events can also indirectly affect anxiety levels by altering depressive symptoms (40, 41). This interaction may stem from the psychological stress, social difficulties, and emotional fluctuations caused by life events, which further exacerbate anxiety levels in adolescents (42). The mediating effect highlights the complex relationship between negative life events and anxiety and depression in children and adolescents. The findings suggest that experiencing negative life events significantly increases the risk of anxiety and depression, underscoring the profound impact of such events on the mental health of young individuals.

To address these challenges, targeted interventions are essential. Schools should implement stress-management programs, including peer education and mindfulness training, which have been shown to alleviate anxiety and depressive symptoms (43). Family-based interventions promoting open communication and reducing unrealistic expectations can mitigate stress. For adolescents affected by the pandemic, online counseling and cognitive-behavioral therapy (CBT) are effective strategies (44, 45). Additionally, structured physical activity programs can enhance resilience and reduce mental health symptoms (31, 32). Policymakers should prioritize low-threshold mental health support systems, ensuring accessibility for at-risk groups. Long-term monitoring and large-scale studies are critical for developing evidence-based interventions tailored to the developmental needs of children and adolescents (46).

This study has several limitations that warrant discussion. Firstly, the cross-sectional design limits the ability to infer causality, as it only captures associations between variables at a single point in time. While this design was selected due to its efficiency and feasibility during the COVID-19 pandemic, it restricts the exploration of dynamic changes and causal pathways. Future research should adopt longitudinal designs to track changes over time and establish more robust causal relationships between variables, such as the impact of negative life events on mental health outcomes. Secondly, the study relies on self-reported measures, including the Adolescent Life Events Scale, SAS, and SDS, which are susceptible to response bias and social desirability bias. Although these tools are widely validated and suitable for assessing subjective experiences, they may not fully capture objective realities. To address this limitation, future studies could incorporate multi-method approaches, such as behavioral observations or physiological assessments, to complement self-reported data and reduce potential biases. Thirdly, the use of convenience sampling may reduce the generalizability of the findings to broader populations. This method was chosen due to logistical constraints and the need for rapid data collection; however, it introduces selection bias and limits the representativeness of the sample. Future research should aim to include more diverse and representative samples using random sampling techniques to enhance the reliability and applicability of the results. Fourthly, the study emphasizes correlations and mediation analyses but lacks experimental or intervention-based evidence to confirm the directional or causal relationships among variables. While the findings provide valuable preliminary insights into potential pathways and mechanisms, future studies should incorporate experimental designs or intervention-based approaches to validate and expand upon these results. Fifthly, this study did not fully explore potential mediators or moderators such as resilience, family support, and coping mechanisms. Future research will focus on these factors to further investigate their roles in the relationship between negative life events, anxiety, and depression, providing a more comprehensive understanding of adolescent mental health. Finally, the study does not delve into the mechanisms by which different types of negative life events influence anxiety and depressive symptoms. Understanding these mechanisms is crucial for developing targeted interventions. Future research should explore these pathways to identify specific mediators and moderators of the relationship between negative life events and mental health outcomes, thereby advancing theoretical frameworks and practical applications in this field.

5 Conclusion

In conclusion, this study highlights the complex interplay between anxiety, depression, and negative life events in children and adolescents, with bidirectional mediating relationships emphasizing the pathways through which negative life events impact mental health. These findings provide a scientific foundation for targeted interventions, including early psychological support, family- and school-based programs, and resilience-building strategies, to help mitigate the adverse effects of negative life events and enhance mental well-being.
