Objectives: This study aimed to investigate the psychological stress experienced by frontline medical staff during the Yangbi Earthquake and to understand how coping strategies and social support influence stress responses.

Methods: From days 3 to 14 post-earthquake, online questionnaires were administered to frontline medical staff to assess perceived social support, coping strategies, and psychological stress responses using the Perceived Social Support Scale (PSSS), Trait Coping Strategies Questionnaire (TCSQ), and Stress Response Questionnaire (SRQ). Data analysis included correlation analysis to explore relationships between variables, multiple linear regression to identify key predictors of stress, and path analysis to determine direct and indirect effects.

Results: A total of 253 valid questionnaires were analyzed, with a participant composition of 81.82% females and 18.18% males, and the majority being nurses (62.06%). Psychological stress responses varied by gender and age, with females and older age groups showing higher physical stress responses (P < 0.05). Correlation and regression analyses indicated that negative coping and lower levels of social support were associated with increased stress responses (P < 0.05). Path analysis revealed that intra-family and extra-family support influenced stress responses directly and indirectly through coping strategies (P < 0.05).

Conclusion: This study suggests that perceived social support directly influences stress responses in frontline medical personnel during disasters, with coping strategies mediating this effect. Future research should explore these dynamics over time through longitudinal studies.

1 Introduction

Natural disasters, particularly earthquakes, often exert significant psychological pressure on affected individuals. In recent years, there has been an increasing recognition of the heightened psychological stress faced by healthcare workers during disaster scenarios, which not only impacts their mental and physical well-being but also their performance in emergency situations (1, 2). Despite this, most existing research has focused on the general population, leaving a notable gap in understanding the unique challenges encountered by healthcare workers, especially those operating in minority regions affected by disasters (37).

On May 21st, 2021, a magnitude 6.4 earthquake struck Yangbi in the Dali Bai Autonomous Prefecture of Yunnan Province, resulting in three fatalities and thirty-four injuries (811). Local emergency and medical departments were among the first to respond, with medical personnel receiving disaster relief instructions and immediately engaging in intensive rescue operations. These frontline medical staff faced prolonged periods of high-intensity work, which significantly elevated their psychological stress levels (1214). Excessive stress in such environments can lead to negative emotions such as anxiety and depression, as well as physical reactions like sleep deprivation, and in severe cases, the development of acute stress disorder (ASD) (1519).

Healthcare workers play a critical role in disaster relief, yet their psychological stress responses, social support and coping strategies, especially in the context of earthquake rescue operations in minority regions, are not well understood. Existing research often fails to account for the specific challenges faced by healthcare workers in areas like Yangbi, China. These workers may experience additional difficulties due to factors such as local practices, language differences, and varying support networks, all of which can affect their stress levels and coping strategies.

This study aims to address this gap by examining the psychological stress responses, social support and coping strategies of healthcare personnel involved in the earthquake rescue operations in Yangbi, Yunnan Province. We used correlation analysis and multiple linear regression to explore the relationships and predictors of stress levels, followed by path analysis to understand the direct and indirect effects among stress responses, social support, and coping strategies. Our hypothesis suggests that social support affects stress responses directly, with coping strategies serving as mediators. By focusing on these unique settings, this research provides insights into the psychological resilience of healthcare workers in minority regions and offers theoretical support for tailored psychological interventions in disaster scenarios.

2 Methods

2.1 Inclusion criteria

Participants were included in the study based on the following criteria: 1) Active frontline medical personnel involved in the earthquake relief efforts on May 21, 2021, which included clinical physicians, nurses, administrative staff, and logistical personnel; 2) Absence of any cognitive impairments, ensuring the ability to understand and independently complete the questionnaire; 3) Informed awareness of the study and voluntary participation; 4) Self-reported absence of any history of physical or mental illnesses at the time of participation.

2.2 Exclusion criteria

Participants were excluded if they self-reported a history of mental or psychological illnesses. This exclusion criterion was intended to ensure that the observed stress responses were directly related to the earthquake relief efforts rather than pre-existing conditions.

2.3 Research design

A cross-sectional study design was used. Data collection was conducted via an online survey distributed through the Wenjuanxing platform (https://www.wjx.cn) after the earthquake. The survey link was shared in work-related WeChat groups associated with clinical, nursing, and administrative departments involved in the relief efforts. Participation was encouraged through departmental announcements. The timeline for data collection was set from the 3rd to the 14th day post-earthquake to align with the acute stress response period, which is critical for capturing the immediate psychological impact on the frontline personnel. The survey was administered once within this period to evaluate the stress responses, perceived social support, and coping strategies following the disaster. Upon accessing the survey, participants were presented with an informed consent form. Only those who met the inclusion criteria and provided consent were allowed to proceed. The survey captured both demographic and psychometric data to comprehensively cover the study variables.

2.4 Data collection

2.4.1 General information

This form collected demographic information such as gender, age, education level, job position, professional title, years of work experience, and the level of the hospital where participants were employed during the earthquake. This information was essential for analyzing the influence of sociodemographic variables on stress responses.

2.4.2 Stress response questionnaire

The SRQ is a validated instrument designed to assess the physical and emotional symptoms that individuals experience in response to social stress. The questionnaire comprises 28 items, categorized into three subscales: Emotional Reactions, which captures the emotional effects of stress; Coping Reactions, which evaluates behavioral responses to stress; and Physiological Reactions, which measures physical symptoms associated with stress. Participants respond to each item on a 5-point Likert scale, where higher scores reflect more significant stress responses. The SRQ has been widely used for stress assessment in disaster contexts (50).

2.4.3 Perceived social support scale

The PSSS measures perceived social support from family, friends, and significant others. The scale consists of 12 items rated on a 7-point Likert scale, with higher scores indicating greater perceived social support (20). This scale is widely used in stress and coping research, providing a robust measure of social support (21).

2.4.4 Trait coping strategies questionnaire

The TCSQ evaluates stable coping strategies tied to personality traits, using 20 items rated on a 5-point Likert scale. It includes two subscales: Positive Coping, which measures adaptive strategies, and Negative Coping, which assesses maladaptive responses. Higher scores indicate greater reliance on the corresponding coping strategy, providing insight into individuals’ habitual stress responses (51).

2.5 Data analysis

Data analysis was conducted using R software version 4.0.3, employing a range of statistical methods. Descriptive statistics were used to summarize the demographic characteristics of the participants. Comparative analyses, including t-tests, ANOVA, and non-parametric tests, were performed to examine differences in stress responses, coping strategies, and perceived social support across demographic groups such as age, gender, and job title. Pearson correlation coefficients were calculated to explore the relationships among stress responses, coping strategies, and social support. Multiple linear regression was used to identify predictors of stress responses, adjusting for confounding factors like age and gender. To further assess and visualize both direct and indirect relationships among stress responses, coping strategies, and social support, path analysis using structural equation modeling was employed. To control for the risk of false positives due to multiple comparisons, we applied the Bonferroni correction, adjusting the p-values by dividing the significance level of each test by the number of comparisons. Statistical significance was set at α = 0.05.

2.6 Quality control

To ensure the quality and integrity of the data, the Wenjuanxing platform tracked IP addresses, allowing only one response per participant. The platform also monitored the time spent on each survey, excluding responses completed in less than 100 seconds to ensure data reliability. The survey was designed to protect participant confidentiality by not collecting sensitive personal information, which encouraged honest and accurate responses.

3 Results

3.1 Overview of study participants

A total of 264 questionnaires were distributed, and 253 valid responses were collected, yielding an effective response rate of 95.8%. Among the participants, 46 were male (18.18%) and 207 were female (81.82%), with ages ranging from 23 to 57 years. The participants included 47 doctors (18.58%), 157 nurses (62.06%), and 49 non-clinical staff (19.36%). Most held junior titles (65.22%), with smaller proportions holding intermediate (17.79%), associate senior (7.9%), and senior titles (1.98%). Regarding work experience, 18.97% had less than 3 years, 28.46% had 3-5 years, 21.74% had 6-10 years, and 30.83% had more than 10 years.

3.2 Stress response, social support, and coping strategies among local medical staff

The local medical staff involved in the rescue reported an average body response score of 17.80 ± 9.03 and a behavior response score of 10.49 ± 5.67. The total stress response score was 52.91 ± 25.39, with an emotional response score of 21.30 ± 10.87. In terms of social support, local medical staff reported intra-family support scores of 22.53 ± 5.59 and extra-family support scores of 42.35 ± 10.31, with a total social support score of 57.32 ± 12.38. Regarding coping strategies, local medical staff exhibited an average positive coping score of 27.54 ± 7.72 and a negative coping score of 35.35 ± 8.86. Detailed results are presented in Table 1.

Table 1. Stress response, social support, and coping strategies among local medical staff (Score, M ± SD).

3.3 Psychological stress response results

Statistical differences were found in physical reactions between different genders, with females exhibiting significantly higher levels of physical reactions than males (P = 0.02). No significant differences were observed in emotional reactions or behavioral reactions between genders. Across age groups, the 45-59 age group exhibited significantly higher physical reactions compared to others (P = 0.03), though emotional reactions, behavioral reactions, and total stress response scores did not differ significantly by age. Additionally, there were no significant differences in psychological stress responses among medical personnel based on professional titles or positions (P > 0.05). Significant differences in psychological stress responses were observed based on years of working experience. Those with 21-30 years of experience had the highest physical reaction scores (M = 24.88, SD = 12.06), as well as the highest scores for emotional reactions (P = 0.006) and behavioral reactions (P = 0.032). Overall, total stress response scores were also highest in the 21-30 years working experience group (P = 0.027). See Table 2 for further details.

3.4 Correlation analysis

Single-factor correlation analysis revealed significant correlations between the psychological stress response of local medical personnel and factors such as positive coping, negative coping, intra-family support, external family support, and total social support (P < 0.05). After adjusting for gender and age-related differences in physical reactions, it was found that negative coping, intra-family support, external family support, and overall social support were negatively correlated with stress response. Detailed results are provided in Table 3.

3.5 Regression analysis of psychological stress response

Multiple linear regression analysis was conducted to examine the effects of positive coping, negative coping, intra-family support, and external family support on the stress response among local medical personnel involved in rescue efforts. The regression model was statistically significant (P < 0.001) and explained 96.8% of the variance in stress response (adjusted R²= 0.968). After adjusting for age and gender, the analysis showed that coping strategies and social support significantly influence psychological stress responses. Positive coping had a standardized coefficient (β) of 0.24 (95% CI: 0.20, 0.27, p < 0.001), while negative coping had a β of 0.09 (95% CI: 0.06, 0.12, p < 0.001). Intra-family support had a strong positive association with stress responses (β = 0.69, 95% CI: 0.59, 0.78, p < 0.001), and extra-family support had the strongest positive association (β = 0.82, 95% CI: 0.77, 0.87, p < 0.001) (Table 4).

3.6 Path analysis of psychological stress response

A path analysis was conducted to examine the direct and indirect effects of intra-family support (X1), external family support (X2), positive coping (X3), and negative coping (X4) on the psychological stress response among frontline medical personnel involved in local rescue efforts. The path diagram (Figure 1) and corresponding coefficients (Table 5) show that intra-family support, external family support, positive coping, and negative coping directly impact stress response, with coefficients of 0.31, 0.68, 0.15, and 0.06, respectively. Additionally, intra-family and external family support indirectly affect stress response through positive and negative coping strategies, with indirect effects of 0.0153 and -0.0069, respectively. These findings suggest that both intra-family and external family support influence psychological stress directly and indirectly by shaping coping strategies, which mediate the relationship between support systems and stress responses.

4 Discussion

This study highlights the significant impact of coping strategies and social support on the psychological stress responses of frontline medical personnel involved in local rescue efforts. The results underscore the importance of positive coping strategies and strong social support in mitigating stress and enhancing overall well-being.

Consistent with previous studies, we observed that higher levels of social support are associated with better mental health outcomes among healthcare workers (2224). Our study further confirms that local medical staff involved in earthquake rescue operations experience significantly higher stress compared to the general population (20). This finding is in line with broader research from disaster contexts, such as the COVID-19 pandemic, where healthcare workers consistently report elevated stress levels. (6, 25, 26).

Gender differences were evident, with female medical staff reporting higher physical stress levels, likely due to different coping strategies, support networks, and physiological stress responses (2729). This suggests the need for gender-sensitive interventions tailored to female healthcare workers’ unique stressors (30). Age-related differences also emerged, with healthcare workers aged 45-59 showing higher stress, potentially due to increased responsibilities or age-related health concerns (3133). Age-specific support strategies could mitigate these stress responses effectively.

Our analysis revealed that work experience significantly impacts stress responses, with workers having 21-30 years of experience reporting the highest stress levels. This could be due to cumulative stress or perceived workload (34, 35). These findings highlight the need to consider work experience when designing support systems and interventions. Tailored strategies, such as peer support programs (36), could help more experienced personnel manage stress more effectively while leveraging their experience to support less experienced colleagues.

Both positive and negative coping strategies were found to impact stress responses, with positive coping having a more substantial effect (β = 0.24) compared to negative coping (β = 0.09). The negative correlation between negative coping and stress suggests that strong social support can buffer stress, even when maladaptive coping strategies are used (37). This highlights the importance of a robust support network in managing stress, even in high-pressure disaster settings.

Our analysis reveals that the paths of influence identified align with the existing literature, emphasizing the crucial role of social support in stress response (3840). Our findings confirm that social support, particularly from external family sources, has direct effects on stress levels, while coping strategies serve as important mediators in this relationship (41, 42). Specifically, external family support emerged as the most significant direct factor influencing stress response, consistent with previous studies highlighting the importance of social support networks, especially in disaster contexts (43, 44).

Moreover, the mediation role of coping strategies, which enhances the benefits of social support, is well-supported by existing literature (45). This is particularly relevant in professional settings, where external support networks can play a crucial role in mitigating work-related stress (46, 47). Notably, our findings suggest that while both internal and external family support are important, the influence of external family support is more significant, potentially due to the unique stressors faced by our participants. This observation underscores the importance of considering the specific characteristics of the study population and the context when interpreting the relative importance of different support systems.

Interestingly, our results also indicate that social support, especially from external sources, is associated with increased reporting of stress. This complexity highlights that while social support does not always reduce stress, it significantly influences how stress is managed and reported (4). Furthermore, reliance on negative coping strategies, even with strong external family support, may increase anxiety levels (48). This finding emphasizes the complexity of the relationship between coping strategies and social support and underscores the need for interventions that are multidimensional and tailored to the specific context of the population at risk (49).

Despite its insights, our study has several limitations. First, the cross-sectional design prevents us from inferring causality between social support, coping strategies, and stress responses. Second, collecting data only once, between days 3 and 14 post-earthquake, restricts our ability to capture fluctuations in stress, support, and coping over time. Third, the small sample size and reliance on self-reported measures may affect the generalizability of our findings and introduce response biases. Additionally, we did not account for confounding factors, such as pre-existing trauma or mental health conditions, which could have influenced the results. Future research should use longitudinal designs with larger, more diverse samples and objective measures to better understand how stress and coping mechanisms evolve over time and in different contexts.

5 Conclusion

This study shows that perceived social support directly impacts stress responses in frontline medical personnel during disasters, with coping strategies serving as mediators. Factors like gender, age, and work experience also significantly affect stress levels, indicating the need for targeted interventions. Strengthening support networks and promoting positive coping strategies are essential for reducing stress. Future research should investigate the long-term dynamics of stress and coping through longitudinal studies.
