<p>Perfectionism can directly and significantly predict interpersonal sensitivity and can also indirectly predict interpersonal sensitivity through Psychological Resilience, Peer Relationships, and Core Self-Evaluation. The traditional Confucian educational philosophy in China advocates core values such as &#x201C;benevolence,&#x201D; &#x201C;righteousness,&#x201D; &#x201C;propriety,&#x201D; and &#x201C;wisdom,&#x201D; emphasizing that individuals should constantly cultivate themselves and their families to achieve moral perfection. This can lead to heightened interpersonal sensitivity and severe psychological repression. Modern education should build on traditional educational values while promoting inclusivity and tolerance, encouraging individuals to focus on the present, accept their emotions and experiences, respect human freedom of development, and safeguard psychological health.</p>

<title>Introduction</title>
<p>Perfectionism is a psychological trait in which individuals set high standards for themselves and others in the pursuit of perfection (<xref ref-type="bibr" rid="ref44">Ma et al., 2010</xref>). It is often characterized by a strong focus on success and performance, along with a deep fear of failure (<xref ref-type="bibr" rid="ref10">Conroy et al., 2007</xref>). Perfectionism can generally be divided into different dimensions, including self-oriented perfectionism (setting high standards for oneself), other-oriented perfectionism (setting high standards for others), and socially prescribed perfectionism (sensitivity to societal expectations) (<xref ref-type="bibr" rid="ref19">Flett et al., 2016</xref>). Perfectionists typically have clear goal orientations, which allow them to focus better on tasks and increase work efficiency (<xref ref-type="bibr" rid="ref18">Flett and Hewitt, 2002</xref>). However, when these goals are not achieved, perfectionists may severely criticize themselves, leading to low self-esteem and negative emotions (<xref ref-type="bibr" rid="ref41">Luo et al., 2016</xref>). Some studies suggest that moderate perfectionism may motivate individuals to pursue excellence and enhance their sense of self-efficacy (<xref ref-type="bibr" rid="ref59">Stoeber and Damian, 2014</xref>). On the other hand, high levels of perfectionism are often associated with psychological issues such as anxiety, depression, social anxiety, and interpersonal relationship difficulties (<xref ref-type="bibr" rid="ref19">Flett et al., 2016</xref>).</p>
<p>Interpersonal sensitivity is a personality type characterized by excessive sensitivity to others&#x2019; behaviors and emotions (<xref ref-type="bibr" rid="ref46">McCabe et al., 1999</xref>). This sensitivity allows individuals to more easily identify and interpret social cues and emotional states of others, but it may also lead them to overfocus on others&#x2019; perceptions and reactions in social situations (<xref ref-type="bibr" rid="ref21">Hall et al., 2009</xref>). Prolonged attention to others&#x2019; emotions may result in emotional exhaustion for the individual, negatively impacting their mental health (<xref ref-type="bibr" rid="ref81">Zhang, 2024</xref>). Interpersonal sensitivity is often closely linked to emotional intelligence, empathy, and self-awareness. Highly sensitive individuals are better at understanding others&#x2019; emotions and are skilled in using interpersonal communication techniques such as verbal communication, body language, active listening, and feedback, leading to higher-quality interpersonal interactions (<xref ref-type="bibr" rid="ref15">Erozkana, 2013</xref>; <xref ref-type="bibr" rid="ref1">Acevedo et al., 2014</xref>). These individuals are more adept at recognizing potential conflicts and addressing them early, thus preventing possible interpersonal disputes (<xref ref-type="bibr" rid="ref62">Trnka, 2013</xref>). However, this heightened sensitivity can also lead to anxiety and discomfort in social situations, as these individuals may worry about being misunderstood or judged (<xref ref-type="bibr" rid="ref69">Wilhelm et al., 2004</xref>).</p>

<title>The relationship between perfectionism and interpersonal sensitivity</title>
<p>Self-determination theory emphasizes the importance of self-assessment and external evaluation for an individual&#x2019;s mental health. Perfectionists often rely on external feedback to confirm their self-worth, which makes them exceptionally sensitive to others&#x2019; opinions, increasing the vulnerability of their interpersonal relationships (<xref ref-type="bibr" rid="ref64">Vicent et al., 2020</xref>). For example, when individuals feel that they have autonomy in setting goals (<xref ref-type="bibr" rid="ref55">Sheldon, 2014</xref>), especially when they perceive support for their autonomy from significant people in their lives, their goal pursuit tends to be successful. On the other hand, if they do not receive support from others, they may feel more discouraged and withdraw from social interactions (<xref ref-type="bibr" rid="ref48">Moore et al., 2018</xref>). A study using the Self-Rating Symptoms Scale (SCL-90) and the Chinese version of the Frost Multidimensional Perfectionism Scale, revised by Yang Hongfei, surveyed 325 medical students. The results indicated a significant correlation between perfectionism and interpersonal sensitivity, which is consistent with findings from other researchers (<xref ref-type="bibr" rid="ref77">Yang and Zhang, 2004</xref>; <xref ref-type="bibr" rid="ref75">Xie, 2004</xref>). Moreover, some studies have shown that perfectionism is closely related to peer relationships (<xref ref-type="bibr" rid="ref26">Huang, 2024</xref>), psychological resilience (<xref ref-type="bibr" rid="ref65">Wang, 2019</xref>), and core self-evaluation (<xref ref-type="bibr" rid="ref83">Zhang et al., 2016</xref>). Based on this, the present study proposes Hypothesis 1: Perfectionism can significantly predict interpersonal sensitivity.</p>

<title>The indirect effect of peer relationships</title>
<p>Peer relationships refer to the relationships between individuals of the same age or with similar levels of psychological development. These are parallel, equal relationships (<xref ref-type="bibr" rid="ref74">Xiao et al., 2024</xref>). Such relationships are typically built on shared interests, values, and experiences, carrying significant social and emotional meaning. Peer relationships generally include three aspects: emotional support, social interaction, and mutual assistance and cooperation. Emotional support refers to the care and support provided by peers to help each other cope with life&#x2019;s challenges. Social interaction involves frequent exchanges between peers, including communication, activities, and collaboration, which strengthen the sense of closeness in the relationship. Mutual assistance and cooperation refer to the collaboration and support between peers in learning, work, or leisure activities, which fosters mutual development (<xref ref-type="bibr" rid="ref50">Reiter and Weller, 2020</xref>).</p>
<p>Good peer relationships help individuals develop social skills and communication abilities, reduce the risk of anxiety and depression, enhance overall mental health, and boost self-esteem and self-efficacy (<xref ref-type="bibr" rid="ref76">Yan, 2019</xref>). In contrast, poor peer relationships may lead to conflicts and competition, which can result in emotional stress and psychological burden (<xref ref-type="bibr" rid="ref73">Xiang et al., 2022</xref>). Studies have shown that perfectionists often experience higher anxiety and lower satisfaction in peer relationships due to their excessive expectations of others and themselves, which can lead to social avoidance and interpersonal conflicts (<xref ref-type="bibr" rid="ref18">Flett and Hewitt, 2002</xref>). The quality of peer relationships is closely related to an individual&#x2019;s interpersonal sensitivity (<xref ref-type="bibr" rid="ref40">Liu et al., 2019</xref>). Based on this, the present study proposes Hypothesis 2: Peer relationships mediate the relationship between perfectionism and interpersonal sensitivity.</p>

<title>The indirect effect of core self-evaluation</title>
<p>There is a close relationship between perfectionism and core self-evaluation. Perfectionists typically have a higher sense of self-efficacy (<xref ref-type="bibr" rid="ref18">Flett and Hewitt, 2002</xref>; <xref ref-type="bibr" rid="ref61">Sun, 2024</xref>), but they are more likely to experience frustration when faced with failure, which can negatively affect their core self-evaluation (<xref ref-type="bibr" rid="ref79">Yu, 2019</xref>).</p>
<p>Core self-evaluation refers to an individual&#x2019;s fundamental assessment of their abilities and worth (<xref ref-type="bibr" rid="ref49">Mubarak and Quinn, 2019</xref>). It reflects how individuals perceive themselves and how this self-perception impacts their behavior and mental health. Core self-evaluation primarily includes four dimensions: self-esteem, self-efficacy, emotional stability, and internal locus of control. According to social comparison theory, perfectionists tend to engage in upward comparisons with others, leading to a more negative core self-evaluation. This comparison not only affects self-esteem but can also lead to anxiety and depression (<xref ref-type="bibr" rid="ref17">Festinger, 1954</xref>). Higher core self-evaluation is associated with better mental health, helping to reduce anxiety and depression (<xref ref-type="bibr" rid="ref72">Wu et al., 2024</xref>). It also promotes greater confidence and initiative in the workplace, enhancing work efficiency (<xref ref-type="bibr" rid="ref39">Liu, 2024</xref>), and contributes to the development of positive interpersonal relationships and social interactions (<xref ref-type="bibr" rid="ref32">Lei et al., 2018</xref>). However, blind overconfidence may lead to arrogance (<xref ref-type="bibr" rid="ref13">Dunning et al., 2003</xref>; <xref ref-type="bibr" rid="ref68">Wen et al., 2016</xref>), which can reduce sensitivity to feedback from others (<xref ref-type="bibr" rid="ref35">Li, 2022</xref>). Based on this, the present study proposes Hypothesis 3: Core self-evaluation mediates the relationship between perfectionism and interpersonal sensitivity.</p>

<title>The indirect effect of psychological resilience</title>
<p>Psychological resilience refers to an individual&#x2019;s ability to adapt, recover, and maintain mental health in the face of adversity, stress, or challenges (<xref ref-type="bibr" rid="ref43">Ma et al., 2024</xref>). This ability enables individuals to effectively cope with difficulties in life and return to a normal state after experiencing trauma. Psychological resilience typically includes four dimensions: emotional regulation, self-efficacy, adaptability, and social support. Psychological resilience helps reduce the risk of anxiety and depression and promotes overall mental health (<xref ref-type="bibr" rid="ref4">Anna, 2024</xref>).</p>
<p>Perfectionists tend to have higher self-efficacy, which may enhance their psychological resilience (<xref ref-type="bibr" rid="ref59">Stoeber and Damian, 2014</xref>). Attachment theory suggests that individuals with high psychological resilience often possess a secure attachment style, which makes them more resilient when facing challenges in interpersonal relationships. In contrast, individuals with high interpersonal sensitivity, due to insecure attachment styles, may over-interpret others&#x2019; responses, leading to emotional instability (<xref ref-type="bibr" rid="ref47">Mikulincer and Shaver, 2007</xref>). Individuals with high psychological resilience are more likely to maintain positive coping strategies under stress (<xref ref-type="bibr" rid="ref2">Aldao et al., 2010</xref>), which helps them maintain a positive attitude in social situations, strengthening their connections and support from others. Research has shown that high psychological resilience is typically associated with lower interpersonal sensitivity, meaning that individuals with high psychological resilience are more adaptable when facing others&#x2019; evaluations. On the other hand, individuals with low psychological resilience may be overly sensitive to others&#x2019; opinions, leading to social anxiety and interpersonal problems (<xref ref-type="bibr" rid="ref38">Liang et al., 2019</xref>). Based on this, the present study proposes Hypothesis 4: Psychological resilience mediates the relationship between perfectionism and interpersonal sensitivity.</p>

<title>The potential indirect effect of peer relationships and psychological resilience</title>
<p>Social support theory suggests that various types of social support, including peer relationships, not only alleviate psychological stress but also enhance an individual&#x2019;s positive coping abilities, promoting the development of psychological resilience (<xref ref-type="bibr" rid="ref56">Sippel et al., 2015</xref>). Perfectionists&#x2019; pursuit of higher-quality friendships may make them overly critical in their interactions with others, which can hinder the healthy development of peer relationships (<xref ref-type="bibr" rid="ref19">Flett et al., 2016</xref>), potentially weakening an individual&#x2019;s psychological resilience and reducing their adaptability in the face of difficulties (<xref ref-type="bibr" rid="ref33">Leng, 2020</xref>). Research has found a significant negative correlation between psychological resilience and interpersonal sensitivity, with individuals possessing high psychological resilience generally being less sensitive to others&#x2019; opinions (<xref ref-type="bibr" rid="ref80">Zhang, 2015</xref>). Based on this, the present study proposes Hypothesis 5: Peer relationships and psychological resilience mediate the relationship between perfectionism and interpersonal sensitivity.</p>

<title>The potential indirect effect of peer relationships and core self-evaluation</title>
<p>Perfectionists may face more challenges in peer relationships. Their perfectionistic tendencies may lead them to have excessively high expectations of others, which can affect the quality and satisfaction of friendships (<xref ref-type="bibr" rid="ref23">Hewitt and Flett, 1991</xref>), often resulting in feelings of isolation and dissatisfaction in their relationships with peers. For example, perfectionists may experience higher anxiety in social interactions, increasing the likelihood of conflicts and misunderstandings (<xref ref-type="bibr" rid="ref19">Flett et al., 2016</xref>). Cognitive behavioral theory suggests that attention should be given to how an individual&#x2019;s thought patterns influence their emotions and behaviors. In peer relationships, positive interactions and feedback can enhance an individual&#x2019;s self-efficacy, thereby improving their core self-evaluation (<xref ref-type="bibr" rid="ref51">Ren, 2017</xref>). In contrast, negative social experiences may lead to negative self-evaluations (<xref ref-type="bibr" rid="ref5">Beck, 1976</xref>; <xref ref-type="bibr" rid="ref6">Brockner et al., 2004</xref>). Improving core self-evaluation is crucial for an individual, as it may help reduce interpersonal sensitivity and improve the quality of social interactions (<xref ref-type="bibr" rid="ref28">Judge et al., 2003</xref>).Based on this, the present study proposes Hypothesis 6: Peer relationships and core self-evaluation mediate the relationship between perfectionism and interpersonal sensitivity.</p>

<sec id="sec12">
<label>1.7</label>
<title>The potential indirect effect of psychological resilience and core self-evaluation</title>
<p>Research has shown that individuals with high levels of perfectionism often exhibit strong psychological resilience because they set high goals and actively confront challenges (<xref ref-type="bibr" rid="ref59">Stoeber and Damian, 2014</xref>). Resilience theory explores the adaptability individuals demonstrate in the face of adversity. Individuals with strong psychological resilience are typically able to cope positively with stress and challenges, and this ability is closely linked to their core self-evaluation (<xref ref-type="bibr" rid="ref45">Masten, 2001</xref>). Individuals with higher psychological resilience tend to have higher core self-evaluation, which enables them to show greater adaptability in adversity (<xref ref-type="bibr" rid="ref8">Chen, 2014</xref>) and to engage confidently in social interactions without worrying about deteriorating relationships (<xref ref-type="bibr" rid="ref52">Schmader et al., 2008</xref>). Based on this, the present study proposes Hypothesis 7: Psychological resilience and core self-evaluation mediate the relationship between perfectionism and interpersonal sensitivity.</p>

<title>The potential indirect effects of peer relationships, psychological resilience, and core self-evaluation</title>
<p>Research has shown that perfectionistic tendencies can influence an individual&#x2019;s performance in social interactions. Perfectionists often have excessively high expectations of themselves and others, which leads to more challenges when establishing and maintaining peer relationships (<xref ref-type="bibr" rid="ref23">Hewitt and Flett, 1991</xref>). Negative peer relationships make it difficult to gain emotional support (<xref ref-type="bibr" rid="ref30">Katz and Arieli, 2013</xref>), which can lower an individual&#x2019;s psychological resilience (<xref ref-type="bibr" rid="ref70">Windle, 2011</xref>). As a result, individuals may feel less confident and have lower self-evaluations.</p>
<p>Some studies have found a significant negative correlation between core self-evaluation and interpersonal sensitivity. Individuals with high core self-evaluation tend to be less sensitive to others&#x2019; feedback and are more confident in handling various social situations, while individuals with low core self-evaluation may be overly sensitive to others&#x2019; opinions, leading to social anxiety (<xref ref-type="bibr" rid="ref52">Schmader et al., 2008</xref>). Based on this, the present study proposes Hypothesis 8: Peer relationships, psychological resilience, and core self-evaluation mediate the relationship between perfectionism and interpersonal sensitivity.</p>

<p>Wenjuanxing, an online data collection, analysis, and management platform founded by Hu Xiao and Wu Yong in November 2006, is the most widely used social survey data platform in China. Since its official operation 18&#x202F;years ago, the platform has released 284 million questionnaires and collected 21.922 billion responses. From November 10, 2023, to February 10, 2024, this study conducted an online survey through the Wenjuanxing platform, obtaining 556 valid responses. During the three-month online survey, the ratio of male to female participants was 36.51 to 63.49%, with 21.77% of participants from urban areas and 78.23% from rural areas.</p>

<title>Psychological Resilience Scale</title>
<p>The Psychological Resilience Scale developed by Hu &#x0026; Gan was used in this study. The scale consists of two dimensions with a total of 27 items. It uses a 5-point Likert scale, where each item has five response options for participants to choose from: Strongly disagree (1 point), Disagree (2 points), Uncertain (3 points), Agree (4 points), and Strongly agree (5 points). Items 1, 2, 5, 6, 9, 12, 15, 16, 17, 21, 26, and 27 are scored reversely, while the remaining items are scored positively. The sum of the scores for all items represents the total score, with a higher total score indicating better psychological resilience (<xref ref-type="bibr" rid="ref25">Hu and Gan, 2008</xref>). In this study, reliability and validity tests were conducted, and the Cronbach&#x2019;s alpha for this scale was 0.90. The structural validity indicators were good: CFI&#x202F;=&#x202F;0.91, TLI&#x202F;=&#x202F;0.90, RMSEA&#x202F;=&#x202F;0.07, SRMR&#x202F;=&#x202F;0.06.</p>

<title>Core Self-Evaluation Scale</title>
<p>The Core Self-Evaluation Scale, translated and revised by Du, Zhang, and Zhao, was used in this study. The revised scale consists of two dimensions with a total of 10 items, using a 5-point Likert scale ranging from &#x201C;Strongly disagree&#x201D; to &#x201C;Strongly agree,&#x201D; with scores of 1&#x2013;5. There are 5 positively scored items and 5 reversely scored items. The higher the participant&#x2019;s score, the higher their core self-evaluation (<xref ref-type="bibr" rid="ref12">Du et al., 2012</xref>). In this study, reliability and validity tests were conducted, with the Cronbach&#x2019;s alpha for the scale being 0.83. The structural validity indicators were good: CFI&#x202F;=&#x202F;0.98, TLI&#x202F;=&#x202F;0.97, RMSEA&#x202F;=&#x202F;0.06, SRMR&#x202F;=&#x202F;0.02.</p>

<title>Interpersonal Sensitivity Questionnaire</title>
<p>We used the interpersonal sensitivity dimension from the SC1-90 Symptom Self-Rating Scale to measure interpersonal sensitivity, which includes 9 items. The scale uses a 5-point rating system, where participants select one option from the five provided: &#x201C;None&#x201D; (1 point), &#x201C;Mild&#x201D; (2 points), &#x201C;Moderate&#x201D; (3 points), &#x201C;Quite severe&#x201D; (4 points), and &#x201C;Severe&#x201D; (5 points). In this study, we used the total score of interpersonal sensitivity as the rating criterion, where higher scores indicate more prominent interpersonal sensitivity issues (<xref ref-type="bibr" rid="ref67">Wang et al., 1999</xref>). In this study, we conducted reliability and validity tests, with the Cronbach&#x2019;s alpha for the scale being 0.95. The structural validity indicators were good: CFI&#x202F;=&#x202F;0.98, TLI&#x202F;=&#x202F;0.97, RMSEA&#x202F;=&#x202F;0.07, SRMR&#x202F;=&#x202F;0.02.</p>

<title>Perfectionism Scale</title>
<p>We used the revised Chinese version of the Frost Multidimensional Perfectionism Scale (<xref ref-type="bibr" rid="ref85">Zi and Zhou, 2006</xref>) as the measurement tool. This scale was revised based on a sample of undergraduate students from mainland China and uses a 5-point rating system, ranging from &#x201C;Strongly disagree&#x201D; to &#x201C;Strongly agree,&#x201D; with scores from 1 to 5. The scale consists of 26 items, all scored positively. The total score is the sum of the individual item scores, with higher scores indicating higher levels of perfectionism (<xref ref-type="bibr" rid="ref85">Zi and Zhou, 2006</xref>). In this study, we conducted reliability and validity tests, with the Cronbach&#x2019;s alpha for the scale being 0.93.

<title>Peer Relationships Scale</title>
<p>The Peer Relationships Scale used in this study is a revised version of the Peer Relationships dimension from the Interpersonal Sensitivity Scale developed by <xref ref-type="bibr" rid="ref71">Wo et al. (2001)</xref>. It includes two dimensions with a total of 17 items. The scale uses a Likert 5-point rating system, where each item has 5 options: &#x201C;Strongly disagree&#x201D; (1 point), &#x201C;Disagree&#x201D; (2 points), &#x201C;Neutral&#x201D; (3 points), &#x201C;Agree&#x201D; (4 points), and &#x201C;Strongly agree&#x201D; (5 points). A higher score indicates poorer peer relationships, while a lower score indicates better peer relationships (<xref ref-type="bibr" rid="ref71">Wo et al., 2001</xref>). In this study, the reliability of the scale was Cronbach&#x2019;s alpha&#x202F;=&#x202F;0.95, and the structural validity indicators were good: CFI&#x202F;=&#x202F;0.95, TLI&#x202F;=&#x202F;0.94, RMSEA&#x202F;=&#x202F;0.08, SRMR&#x202F;=&#x202F;0.03.</p>

<title>Data analysis strategy</title>
<p>We used SPSS 25.0 to calculate the means, standard deviations, reliability coefficients, and correlation coefficients for Perfectionism, Psychological Resilience, Interpersonal Sensitivity, Core Self-Evaluation, and Peer Relationships. This helped us understand the levels of these variables among Chinese individuals. Confirmatory factor analysis (CFA) of the scales was conducted using Mplus 8.0 to test the internal structural validity of the scales. In evaluating model fit indices, we required the following criteria for the model&#x2019;s fit: RMSEA &#x003C;0.1, SRMR &#x003C;0.1, TLI&#x202F;&#x003E;&#x202F;0.9, CFI&#x202F;&#x003E;&#x202F;0.9 (<xref ref-type="bibr" rid="ref7">Brown, 2015</xref>).</p>
<p>In exploring the relationships between variables, we used Mplus 8.0 to construct structural equation models, which were analyzed in two main procedures. We established a structural equation model with Perfectionism as the independent variable, Interpersonal Sensitivity as the dependent variable, and Peer Relationships, Psychological Resilience, and Core Self-Evaluation as mediating variables. For testing the significance of both independent indirect effects and chain indirect effects, we used the Bootstrap method with a 95% confidence interval for bias-corrected bootstrapping. Indirect effects were considered significant if the confidence interval did not include zero.</p>

<title>Common method bias test</title>
<p>when researchers use a single data collection method (such as a questionnaire), respondents may answer multiple scales at the same time, and the way questions are phrased and ordered can lead to higher consistency in responses (<xref ref-type="bibr" rid="ref78">Yu, 2012</xref>). To avoid common method bias in this study, we used Harman&#x2019;s single-factor method for exploratory factor analysis (<xref ref-type="bibr" rid="ref82">Zhang et al., 2024</xref>). A total of 16 factors with eigenvalues greater than 1 were obtained, with the first factor explaining 26.02% of the total variance, which is below the 40% threshold (<xref ref-type="bibr" rid="ref20">Guo et al., 2023</xref>), indicating that there is no significant common method bias.</p>

<title>Descriptive statistics and correlation analysis</title>
<p>We calculated the mean, standard deviation, correlation coefficient, skewness, and kurtosis for the scores of Perfectionism, Psychological resilience, interpersonal sensitivity, Core self-evaluation, and Peer relationships. In the normality test of the data in this study, we used the criterion that the absolute value of skewness should be less than 2 or the absolute value of kurtosis should be less than 7 to determine if the data follows a normal distribution (<xref ref-type="bibr" rid="ref31">Kim, 2013</xref>). The results showed that the absolute values of the skewness and kurtosis for the five variables in this study were within the acceptable range, indicating that the collected data approximates a normal distribution and is suitable for statistical analysis.</p>

<title>Discussion</title>
<p>This study found that Perfectionism can significantly predict interpersonal sensitivity, supporting Hypothesis 1 and aligning with self-determination theory. The cognitive model suggests that it is not the situation itself that affects people&#x2019;s feelings, but rather how they interpret the situation. Individuals with perfectionistic tendencies may experience anxiety and self-doubt due to setting high standards. They tend to engage in harsh self-criticism, and their sense of self-worth is often dependent on external validation and feedback from others (<xref ref-type="bibr" rid="ref54">Sharon et al., 2014</xref>). This can lead to an exaggerated sensitivity to their own or others&#x2019; reactions (<xref ref-type="bibr" rid="ref16">Fenn and Byrne, 2013</xref>). This dependency makes them highly sensitive to others&#x2019; perceptions, sometimes viewing others&#x2019; evaluations as direct reflections of their own value. When they perceive negative feedback from others, they may experience strong emotional reactions (<xref ref-type="bibr" rid="ref37">Liang, 2023</xref>). Perfectionists often set unrealistic standards and expectations, not only for themselves but also for others. They hold similarly stringent expectations regarding others&#x2019; behaviors and reactions. When others&#x2019; performances fail to meet these expectations, they are likely to feel disappointed and dissatisfied in social interactions (<xref ref-type="bibr" rid="ref58">Stoeber, 2014</xref>). Prolonged stress in perfectionists can significantly affect their physical health (<xref ref-type="bibr" rid="ref57">Soo et al., 2009</xref>; <xref ref-type="bibr" rid="ref27">Johnson et al., 2014</xref>). This study suggests that each person is an independent individual, with their thoughts and beliefs influenced by their social environment, family background, and education. As a result, individuals&#x2019; ways of thinking inevitably differ to some degree. Striving to improve oneself is a positive behavior that benefits personal growth and development. However, excessive pursuit of perfection can not only be detrimental to one&#x2019;s mental and physical health but can also harm relationships with others. The correct mindset should be that if effort does not lead to satisfactory results, one should learn to be forgiving of oneself. Similarly, we should be tolerant of those around us and accept that they may not be the same as us.</p>
<p>This study found that Perfectionism can significantly predict interpersonal sensitivity through independent indirect effects via Peer relationships, Core self-evaluation, and Psychological resilience, supporting Hypotheses 2, 3, and 4, as well as supporting social comparison theory and attachment theory. Firstly, Perfectionism significantly predicts interpersonal sensitivity through Peer relationships. The multidimensional Perfectionism model proposed by Hewitt and Flett suggests that Perfectionism not only impacts individuals&#x2019; self-assessment but also plays a significant role in interpersonal relationships. Highly perfectionistic individuals often exhibit competitive behaviors to maintain their self-image, which can cause discomfort among peers. In order to maintain their Peer relationships, they become more focused on others&#x2019; opinions and reactions (<xref ref-type="bibr" rid="ref24">Hewitt et al., 2002</xref>). They tend to impose high expectations on others, which may provoke others&#x2019; resentment, thereby making interpersonal relationships more tense and sensitive (<xref ref-type="bibr" rid="ref29">Kang and Chen, 2012</xref>). However, when they notice their peers outperforming them, they may engage in self-deprecation, causing a decrease in their self-confidence and social abilities (<xref ref-type="bibr" rid="ref19">Flett et al., 2016</xref>). It should be noted, however, that in this study, the researchers found a positive correlation between Perfectionism and Peer relationships. This may be due to the sample size. Future research should employ larger sample sizes through surveys and interviews, which may yield more scientifically accurate results. Additionally, the participants in this study may not be extreme perfectionists; their competitive behavior may not yet severely damage their Peer relationships, which might explain the observed positive correlation. Secondly, Perfectionism significantly predicts interpersonal sensitivity through Core self-evaluation. The Core self-evaluation model suggests that while perfectionists may have intrinsic achievement motivation that helps maintain a positive mindset, the high standards and expectations they set for themselves are often difficult to achieve. This can lead to excessive self-doubt, affecting their Core self-evaluation (<xref ref-type="bibr" rid="ref23">Hewitt and Flett, 1991</xref>). As a result, they may exhibit higher levels of self-criticism (<xref ref-type="bibr" rid="ref18">Flett and Hewitt, 2002</xref>; <xref ref-type="bibr" rid="ref66">Wang, 2023</xref>). Generally, when individuals hold negative views about their own abilities and worth, they may feel anxious and insecure in social situations. This anxiety makes them more sensitive to others&#x2019; reactions and increases their concern about interpersonal relationships (<xref ref-type="bibr" rid="ref53">Schunk and Zimmerman, 2008</xref>). Thirdly, Perfectionism significantly predicts interpersonal sensitivity through Psychological resilience. The motivation and adaptation model emphasizes how an individual&#x2019;s motivation affects their adaptability, especially when facing challenges and stress. For perfectionists, intrinsic achievement motivation drives them to pursue high standards, while maintaining a positive mindset in the face of failure, thus enhancing their resilience (<xref ref-type="bibr" rid="ref14">Egan et al., 2011</xref>). In other words, this motivation is often associated with positive self-improvement and Psychological resilience (<xref ref-type="bibr" rid="ref84">Zhou, 2014</xref>). The stronger the individual&#x2019;s achievement motivation, the higher their Psychological resilience tends to be, making them more capable in coping strategies, stress management, and negative emotion regulation. This enables them to demonstrate greater confidence and stability in social interactions, reducing excessive sensitivity to interpersonal relationships (<xref ref-type="bibr" rid="ref8">Chen, 2014</xref>). In fact, Chinese society has always placed great importance on interpersonal communication, yet surprisingly, the education system in China has not emphasized the cultivation of this quality in children. With the rapid development of the information age, more and more Chinese youth have become addicted to online games, reducing their opportunities for social interaction, which increases difficulties in their interpersonal relationships (<xref ref-type="bibr" rid="ref34">Li, 2016</xref>). The number of individuals experiencing psychological issues has also risen sharply, leading to confusion and a lack of solutions in current mental health institutions (<xref ref-type="bibr" rid="ref36">Li and Du, 2024</xref>). We believe that families, schools, and society should take on this responsibility, strictly limit online game services for minors, and encourage participation in social activities. This would be greatly beneficial for improving social skills.</p>
<p>This study found that the &#x201C;Peer relationships-Psychological resilience,&#x201D; &#x201C;Psychological resilience-Core self-evaluation,&#x201D; and &#x201C;Psychological resilience-Core self-evaluation&#x201D; dual indirect effects significantly predicted interpersonal sensitivity, supporting Hypotheses 5, 6, and 7, as well as supporting social support theory, resilience theory, and cognitive-behavioral theory. Firstly, the &#x201C;Peer relationships-Psychological resilience&#x201D; dual indirect effect plays a significant role in the relationship between Perfectionism and interpersonal sensitivity. Research shows that perfectionists, due to their tendency to hide their vulnerabilities and problems, may reduce opportunities to receive emotional support from peers (<xref ref-type="bibr" rid="ref60">Stoeber et al., 2015</xref>). This leads them to feel more isolated in the face of stress and lack support from those around them. Emotional support from peers not only significantly enhances their Psychological resilience and reduces anxiety but also improves their coping ability in social interactions (<xref ref-type="bibr" rid="ref3">Allen et al., 2016</xref>). Secondly, the &#x201C;Psychological resilience-Core self-evaluation&#x201D; dual indirect effect plays a significant role in the relationship between Perfectionism and interpersonal sensitivity. <xref ref-type="bibr" rid="ref9">Chen et al. (2018)</xref> pointed out that perfectionists may struggle with emotional regulation, leading them to exhibit lower Psychological resilience under stress, which in turn affects their mental health (<xref ref-type="bibr" rid="ref9">Chen et al., 2018</xref>). Individuals with low Psychological resilience tend to show negative self-perception when facing challenges, and this cognitive feedback contributes to lowering their Core self-evaluation (<xref ref-type="bibr" rid="ref63">Tugade and Fredrickson, 2004</xref>). As a result, individuals often lack confidence in interpersonal communication, struggle with complex social relationships, and are more sensitive to interpersonal issues (<xref ref-type="bibr" rid="ref42">Luthans et al., 2006</xref>). In the three significant dual-mediation paths between Perfectionism and interpersonal sensitivity, we must emphasize the roles played by Peer relationships, Psychological resilience, and Core self-evaluation, especially since there is also significant influence between these variables. This study suggests that Confucianism has influenced Asian countries for over 2,000&#x202F;years, and there is a widespread pursuit of perfection in Chinese thought, which brings immense psychological pressure. However, the negative impact felt by different individuals varies, and this is mainly due to differences in each person&#x2019;s social support system and psychological resilience (<xref ref-type="bibr" rid="ref11">Deng, 2017</xref>). It is recommended that the Chinese education system should place more emphasis on teaching children emotional management skills and techniques, such as mindfulness, meditation, and relaxation techniques, as these measures can effectively help them maintain psychological balance.</p>
<p>This study found that the &#x201C;Peer relationships-Psychological resilience-Core self-evaluation&#x201D; triple indirect effect significantly predicted interpersonal sensitivity, supporting Hypothesis 8. <xref ref-type="bibr" rid="ref18">Flett and Hewitt (2002)</xref> pointed out that perfectionists tend to feel uneasy and anxious in social situations, which may lead them to avoid social interactions, thus limiting their contact and communication with peers (<xref ref-type="bibr" rid="ref18">Flett and Hewitt, 2002</xref>). This may result in individuals experiencing higher emotional stress, lowering their Psychological resilience and coping abilities (<xref ref-type="bibr" rid="ref22">Hawkins et al., 2015</xref>), and making it more likely for them to lose control over negative emotions, which in turn leads to greater interpersonal sensitivity (<xref ref-type="bibr" rid="ref42">Luthans et al., 2006</xref>).</p>

<title>Limitations and implications</title>
<p>We must acknowledge several limitations in this study. First, the sample size collected through an online format is relatively small, and the sample may not be fully representative. Second, the data used in this study are cross-sectional, which may not accurately reflect the causal relationships between variables. Therefore, future research could explore cross-lagged studies to investigate the relationships between variables over time.</p>

<title>Conclusion</title>
<p>Perfectionism in Chinese individuals not only directly predicts interpersonal sensitivity but also predicts it through the indirect effects of peer relationships, psychological resilience, and core self-evaluation. Confucius, a prominent figure in Chinese Confucianism, advocated for individuals to become morally virtuous and emphasized the importance of etiquette in interpersonal interactions. While the pursuit of high standards is admirable, excessive perfectionism and the pressure to maintain relationships can make interpersonal connections in China more complex and hinder psychological growth in highly stressful situations. From this perspective, Chinese society should promote moderate self-requirements and a tolerant attitude toward life and interpersonal relationships in order to address the increasingly prominent mental health issues in recent years.</p>
