Introduction
Nursing is a profession centered on aiding and supporting others, requiring nurses to effectively manage interpersonal relationships in problem-solving, decision-making, and professional conduct [
1]. Accordingly, in addition to acquiring knowledge and skills, nursing students must develop the ability to navigate interactions with diverse individuals and situations [
2].
However, interpersonal sensitivity, as a personality trait, has been shown to exhibit susceptibility and variability in response to external factors (e.g., interactions with diverse individuals and situations) [
3]. In addition, individuals with heightened interpersonal sensitivity in the workplace often exhibit a more pessimistic outlook compared to their counterparts, which can lead to conflicts with others and challenges in effectively managing interpersonal relationships [
4]. Moreover, individuals with higher interpersonal sensitivity are attuned to perceived or actual criticism and rejection, prompting them to adjust their behavior to align with the expectations of those around them, further contributing to their reluctance to interact with others [
4]. Consequently, these individuals are often avoided by their peers, resulting in increased feelings of isolation. This state of isolation can be characterized as loneliness, defined as the subjective feeling of a lack of social contact [
5].
One study has established an association between interpersonal sensitivity and loneliness among individuals aged 17 to 26 years [
6]. This robust association still exists in other special studies, such as those involving Chinese gay men [
7]. Another study conducted among Chinese college students has shown a positive correlation between interpersonal sensitivity and negative emotions [
8], as well as an association with individuals’ mobile phone addictions [
9], which are in turn associated with feelings of loneliness [
10]. Nonetheless, there is a lack of investigations examining the central symptoms and bridge symptoms of interpersonal sensitivity and loneliness.
Central symptoms and bridge symptoms are essential for providing precise descriptions of salient symptoms. In contrast to the conventional practice of relying on total scale scores, central symptoms within the network highlight the significance of a node [
11]. For example, a study has demonstrated that central symptoms are essential for identifying key symptoms in the association between depression and anxiety, as well as for effectively developing targeted intervention strategies [
12]. Moreover, bridge symptoms within the network are pivotal in both perpetuating and fostering comorbidities, offering valuable insights for preventing and managing these concurrent conditions [
13]. Currently, central symptoms and bridge symptoms are revealed through network analysis. For instance, based on network analysis, a study has identified the core role of loneliness in the network structure of paranoia dimensions (i.e., interpersonal sensitivity, mistrust, and ideas of persecution) in the general population, proposing that addressing loneliness may serve as a beneficial focal point for clinical intervention [
11].
To date, there is a dearth of research investigating the association between interpersonal sensitivity and loneliness symptoms utilizing a network model among college nursing students. This knowledge gap motivated the current study, which aimed to explore the associations between interpersonal sensitivity and loneliness symptoms in Chinese college nursing students through a network analysis approach. Ultimately, these findings can inform public health policies and interventions designed to enhance the well-being of individuals during their college life.
Discussion
To our knowledge, this study marks the first effort to outline the network of interpersonal sensitivity and loneliness among college nursing students. Positive correlations were noted between loneliness and most items of the IPSM-CS. Furthermore, the analysis indicated that ‘Feel happy when someone compliments’ (IPSM-CS9) exhibited the highest node strength within the network, with ‘They would not like me’ (IPSM-CS2) following closely behind. In addition, central symptoms (i.e., ‘Feel happy when someone compliments’ and ‘They would not like me’) and bridge symptoms (i.e., ‘Relational loneliness’, ‘Intimate loneliness’, and ‘Social loneliness’) were also recognized in this network. Finally, the network comparison test revealed a significant difference in network structure invariance between rural and urban college nursing students and between individuals with or without symptoms of anxiety and depression.
The degree of loneliness exhibited positive associations with most interpersonal sensitivity items. Previous studies have established an association between interpersonal sensitivity and loneliness among individuals aged 17 to 26 years or Chinese gay men [
6,
7]. One possible explanation for this association is that nursing students with higher levels of interpersonal sensitivity, being more attuned to the attitudes and behaviors of others, may experience discomfort or distress in social interactions, which can lead to a tendency to avoid social situations and exacerbate feelings of loneliness [
35]. Moreover, nursing students frequently bear emotional burdens arising from patients’ suffering, particularly during clinical placements and practical experiences [
36]. Prolonged exposure to these emotional burdens can contribute to emotional stress, fatigue, and an increased sense of loneliness among these students [
37]. These findings underscore the importance of providing nursing students with psychological support and strengthening their social support networks. Providing mental health support for nursing students can assist them in effectively coping with emotional stress, thereby reducing feelings of loneliness and promoting their psychological well-being and academic performance.
‘Feel happy when someone compliments’ (IPSM-CS9), which belonging to the category of need for approval exhibited the highest strength in the entire network, highlighting its significant role in the network of interpersonal sensitivity and loneliness among college nursing students. The node index of strength plays a crucial role in identifying influential symptoms that trigger and sustain psychopathological networks, serving as potential targets for interventions [
11]. The reason why the need for approval is particularly important for nursing students may lie in the fact that nursing students often have to deal with heavy academic workload, and approval can provide emotional affirmation and encouragement, helping to enhance their confidence and motivation to cope with various challenges in their work [
38]. In this study, we observed that ‘They would not like me’ (IPSM-CS2), which belongs to the category of fragile inner self also demonstrated high node strength values, suggesting its potential significant role in triggering and sustaining the network of interpersonal sensitivity and loneliness among college nursing students. A potential explanation for this phenomenon is that a fragile inner self typically indicates that nursing students respond with heightened sensitivity and intensity to emotions, rendering them more vulnerable to external circumstances and the actions of others, subsequently exacerbating interpersonal sensitivity and feelings of loneliness [
39].
The most robust edge within the interpersonal sensitivity and loneliness network among college nursing students was observed between ‘Feel happy when someone compliments’ (IPSM-CS9) and ‘Make others happy’ (IPSM-CS10), both of which belong to the category of need for approval. The existence of this strong edge may be attributed to the characteristics of the nursing profession. Nursing students are required to engage in self-disclosure by demonstrating care, patience, and empathy to meet the emotional needs of patients, which leads to a desire for recognition and approval from others [
40]. In addition to the influential edges in interpersonal sensitivity, several robust connections were identified within loneliness. The strongest link was observed between ‘Relational loneliness’ (T-ILS1) and ‘Social loneliness’ (T-ILS2). Initially, nursing students dedicate a substantial portion of their time and effort to academic studies and clinical training, which diminishes their availability for social interactions and the maintenance of relationships, consequently heightening their sense of social loneliness [
41]. Furthermore, the nature of the nursing profession dictates that nursing students will encounter more difficulties and challenges [
36]. They may experience relational loneliness when they lack support and understanding from their peers or teachers in the face of these challenges [
41]. Based on our findings, meeting the need for approval among nursing students and providing social support to decrease feelings of social loneliness and relational loneliness may help alleviate issues related to interpersonal sensitivity and loneliness.
In this interpersonal sensitivity and loneliness network among college nursing students, the most impactful bridge symptom was loneliness symptom of ‘Relational loneliness’ (T-ILS1), indicating that this particular symptom should be a focal point for interventions aimed at alleviating interpersonal sensitivity and loneliness. In one study, loneliness symptoms were recognized as playing a core role in the network of paranoia dimensions and mental health correlates [
11]. Findings from a sample of the general population also revealed that well-being was more adversely associated with nodes linked to loneliness than with nodes associated with more severe psychopathological symptoms. One potential reason for this could be the pivotal role that relational loneliness may result in a lack of emotional support, social support, and a sense of belonging among nursing students, leading to the development of other forms of loneliness, such as social loneliness, and subsequently reducing their life satisfaction and quality of life [
42]. Low social support and quality of life can further trigger interpersonal sensitivity [
43]. Other impactful bridge symptoms encompassed the loneliness symptom of ‘Intimate loneliness’ (T-ILS3) and ‘Social loneliness’ (T-ILS2), indicating that these symptoms should also be addressed in interventions. Therefore, for nursing students, alleviating feelings of loneliness can potentially encourage them to actively engage in social activities, cultivate positive interpersonal relationships, and consequently reduce the occurrence of interpersonal sensitivity.
Based on previous studies, interpersonal sensitivity showed gender and urban-rural differences [
31,
32], and patients with depression and anxiety had higher scores on the IPSM [
33,
34]. The study conducted a network comparison test, which revealed significant differences in network structure invariance between rural and urban college nursing students, between individuals no anxiety symptoms and those having anxiety symptoms, and between individuals no depression symptoms and those having depression symptoms. This outcome can be explained by several factors. On one hand, urban areas, characterized by greater access to specialized healthcare and educational resources, may unwittingly affect the manifestation of interpersonal sensitivity and loneliness symptoms [
44]. In contrast, rural regions often face resource constraints and a lack of mental health awareness could give rise to distinct symptom networks [
45]. On the other hand, in comparison to college nursing students without anxiety and depression, those experiencing anxiety and depression may be more prone to over-interpret the behaviors or words of others, leading to distinct networks of interpersonal sensitivity and loneliness [
46]. These findings suggest the need for tailored intervention measures based on the unique network structures for these two distinct groups of college nursing students. This particular discovery was not identified in the relevant studies utilizing network analysis and warrants further investigation in future research. Additionally, in other comparisons (such as no depression vs. having depression and male vs. female), no noteworthy differences were observed.
It is essential to acknowledge several potential limitations in our study. First, the network structure of interpersonal sensitivity and loneliness symptoms was established among college nursing students using cross-sectional data, which precluded the determination of causality among individual symptoms and exhibited restricted representativeness. Accordingly, the outcomes necessitate validation in forthcoming longitudinal studies. Secondly, self-reported assessments were employed to evaluate interpersonal sensitivity and loneliness symptoms, potentially introducing recall bias and limiting the ability to capture clinical phenomena accurately. Thirdly, it is necessary to acknowledge that methods for network analysis and development are evolving. Future studies should focus on such statistical optimization methods, as these may enhance the understanding of the results and facilitate deeper exploration of the research findings. Finally, although the current results underscore the interpersonal sensitivity and loneliness network among Chinese college nursing students, it is crucial to acknowledge that the applicability of these findings to additional populations may be constrained. Thus, as future study unfolds in the area, cumulative history analysis will be necessary.
