Post-Traumatic Growth during COVID-19: The Role of Perceived Social Support, Personality, and Coping Strategies

Although many studies on mental health have been conducted among various populations during the COVID-19 pandemic, few studies have focused on post-traumatic growth (PTG) in the general population. The current study aimed to explore whether perceived social support, personality, and coping strategies are associated with PTG in the COVID-19 pandemic period. The study also investigated whether coping strategies mediate the relations between perceived social support, personality, and PTG. A total of 181 participants (Mage = 24) completed the self-report questionnaire online, which was distributed via various online channels, mainly in China and Sweden. The relations between the study variables were examined with correlation analyses and a multiple mediation analysis. Results showed that more than half of the participants (60.8%) reported experiences of PTG during the pandemic. Additionally, perceived social support, personality traits (extraversion, emotional stability, agreeableness, and conscientiousness) and coping strategies (problem-focused coping, emotion-focused coping, and social support coping) were positively correlated with PTG. In addition, coping strategies (problem-focused coping, emotion-focused coping, and avoidance coping) mediated the relations between perceived social support, personality traits and PTG. Theoretical and practical implications of this study are discussed, concluding that the findings of this study have the potential to guide intervention efforts to promote positive change during the pandemic.


Introduction
Since the advent of the COVID-19 pandemic, its adverse consequences on mental health have been increasingly elaborated on [1,2]. Although research has also recently started paying attention to positive aspects of pandemic experiences [3], still little is known about the pandemic's potential positive psychological outcomes and to what extent and how this may trigger post-traumatic growth (PTG) [4]. The current study aims to fill these research gaps.
PTG is defined as the subjective experience of positive psychological change reported by an individual as a result of struggling with trauma [5,6]. A meta-analysis indicated that 50-60% of people exposed to potentially traumatic events are likely to experience some degree of PTG [7], which leaves a possibility that PTG might have occurred during the COVID-19 pandemic.
The psychological process growing out of adversity is challenging and may require personal, interpersonal and sociocultural characteristics [6,8]. The current study examined factors that might influence PTG during the context of COVID-19, including situational characteristics (social support) and personal characteristics (personality traits and coping strategies). The findings are expected to show whether and how the general population experienced PTG during the COVID-19 pandemic and, therefore, to guide policymakers and practitioners in developing meaningful practices and interventions for future pandemic

Social Support and Post-Traumatic Growth
The Functional Description Model of Tedeschi and Calhoun [6] explains the development of PTG. Tedeschi et al. believed that traumatized individuals have their core beliefs challenged and experience emotional struggles, and that growing out of adversity requires personal characteristics and sociocultural characteristics. Specifically, an individual's personal characteristics (e.g., personality) influences how they experience the traumatic event. Social support (e.g., material or emotional comfort and support from the outside world) and positive coping processes (e.g., detachment from unachievable goals and unsustainable beliefs; reduction of emotional distress through effective emotion regulation strategies) help the individual to move on from their struggle with trauma. Therefore, PTG is achieved through the interplay of personal characteristics (e.g., personality), sociocultural influences (e.g., social support), and cognitive processes (e.g., coping strategies), as well as other factors [6,8].
Social support is a common predictor included in many previous studies on PTG [20,21]. Social support has been widely interpreted in two ways: perceived social support and received social support [22]. Perceived social support concerns the subjective evaluation of how individuals perceive friends, family members as available to provide material, and psychological and overall support during times of need, whereas received support relates to the actual quantity of support received [22]. The relationship between perceived social support and PTG was explored in this study. It is widely believed that high perceived social support predicts high PTG [21,[23][24][25][26]. Given that several studies have reported that people during COVID-19 often feel isolated and alienated and have difficulty accessing social support [27], there is a need to further clarify the role of perceived social support within PTG during the COVID-19 pandemic.

Personality Traits and Post-Traumatic Growth
Different empirical studies provide varying degrees of evidence to support the positive relationship between personality traits and PTG, including extraversion [6,26,28], agreeableness [29], conscientiousness [26,28,30], and optimism [31,32]. The findings on emotional stability are inconsistent; some studies did not show any significant relationship with PTG [33], while others showed a positive relationship [28]. The findings on openness to experience are also inconsistent. Some studies did not reveal any significant relationship with PTG [34,35], while others demonstrated a positive relationship [6,30]. Few studies have explored the relationship between personality traits and personal growth in the context of the pandemic [30], especially during the COVID-19 pandemic, so further research is needed to explore the relationship between personality and PTG.

The Role of Coping Strategies on Post-Traumatic Growth
Coping strategies have been widely examined as one of the factors in the PTG process [36]. Different coping strategies are associated with differences in psychological adjustment [3,37]. First, most studies have shown that problem-focused coping, such as active coping and planning, are positive predictors of PTG [38,39]. Second, research has found that emotion-focused coping, such as acceptance and positive reframing, can facilitate meaning-making and encourage PTG [20,38,40]. Third, few studies have directly explored the relationship between social support coping and PTG. Some relevant research suggests that people who actively seek social support to help manage stressors may also be more effective at coping with traumatic stressors [41], which is supported by a post-earthquake PTG study which reported that people who were more willing to seek help had higher PTG [42]. Fourth, an increasing number of studies have explored the relationship between avoidance-coping and PTG [38,43,44]. Some studies have shown that avoidance-coping is a maladaptive coping strategy [38,39,45]. However, emerging research has indicated that avoidance-coping decreases symptom distress and increases PTG [43,46,47]. Avoidant coping may play an adaptive role some time after a traumatic event [43,46]. Furthermore, coping may be flexible across situations, with strategies that are effective in specific events and not effective in others [48]. Thus, it is worthwhile to explore the relationship between coping strategies and PTG during the COVID-19 pandemic.
Previous studies have also shown that coping strategies play a mediating role between other situational/personal factors and PTG [20,42,49,50]. First, coping strategies supported by empirical research (problem-focused coping, emotion-focused coping and social support coping) were found to mediate the relationship between perceived social support and PTG [20,42,50,51]. That is, individuals who perceive strong social support are likely to be more capable of using appropriate coping strategies, and therefore more likely to report PTG [20]. Second, the relationship between personality traits and PTG is mediated through various coping processes [49]. Researchers suggested that adaptive coping mediated the relationship between the five-factor personality and PTG [52]. Research has shown that individuals with high extraversion scores adopted higher levels of problem-focused coping and social support coping. Furthermore, research has found that problem-focused coping mediates the relationship between extraversion and PTG [34]. At the same time, individuals with high conscientiousness, agreeableness and emotional stability presented with higher levels of problem-focused coping and emotion-focused coping [53,54]. A study supported the mediating role of problem-focused coping in the relationship between conscientiousness and positive emotions [55]. What is lacking in the literature is about how four coping strategies mediate the relationship between perceived social support, personality and PTG during the COVID-19 pandemic in particular.

The Present Study
This study aims to examine the role of perceived social support, personality, and coping strategies within PTG. In addition, this study investigates the mediation effect of coping strategies in the relation between perceived social support, personality and PTG.
The hypotheses of the current study are as follows: 1 (H1.1). Perceived social support is positively correlated with PTG.   Coping strategies (problem-focused, emotion-focused, and social support coping) mediate the relationship between perceived social support and PTG.

Hypotheses 2.2 (H2.2).
Coping strategies (problem-focused, emotion-focused, and social support coping) mediate the relationship between personality traits (extraversion, agreeableness, and conscientiousness) and PTG. Figure 1 shows the hypothesized model. No hypotheses were generated for openness, emotional stability, and avoidance coping due to inconsistent findings in the literature and, therefore, these are exploratory in nature.

Procedures and Participants
The convenience sampling method was used in this cross-sectional quantitative study. The data were collected through Qualtrics, an Internet-based survey platform, which provides multiple fraud detection options to increase data quality, including enabling multiple submission prevention and detecting duplicated responses. According to ExpertReview, a data quality check feature in the Qualtrics platform, the responses of this study were considered reliable and there were no duplicate respondents.

According to ExpertReview, a data quality check feature in the Qualtrics platform, the responses of this study were considered reliable and there were no duplicate respondents.
After an online survey was constructed, a pilot test was first conducted with 11 respondents to assess the clarity and the response time of the questionnaires (about 10 min), and data from the pilot study were not included in the final data analysis. Then the link to the formal survey was distributed from 25th April to 5th May 2021 via a social media (Facebook), an online discussion forum (Reddit), and instant messaging apps (WhatsApp and WeChat). The inclusion criteria for participants in this study were: (1) an age range of 18 years and older, and (2) the ability to use English proficiently.
Of the 213 participants who took part in the surveys, 32 were excluded because the respondent did not complete the survey. A chi-square analysis showed that there were no significant differences in the demographic characteristics between those who completed the survey and those who did not do so. Therefore, 181 surveys were used for further analyses, resulting in an 85.0% rate of completion. The sample was predominantly female (70.2%) with a mean age of 24.68 years (SD = 5.40).

Measures
Based on the research purposes, we chose questionnaires that were widely known and used in the literature on PTG and in the literature on stress and coping, including the Posttraumatic Growth Inventory-Short (PTGI-S) [19,44], Multidimensional Scale of Perceived Social Support (MSPSS) [20,51], The Ten-Item Personality Inventory (TIPI) [56], and Brief COPE Questionnaire [29]. In addition to these measures, a demographic information form was administered to the participants, which includes information on their gender, age, employment status, country of residence, and living situation during COVID-19. Given the uneven distribution of the pandemic around the world (7 January 2022, https://coronavirus.jhu.edu/map.html) and the different policies in each country (e.g., lockdown or not), which has been shown to be strongly related to people's mental health [27], the country of residence was chosen for this study instead of the country of origin. The questions were modified to specifically ask respondents to indicate their situation during the COVID-19 pandemic.

The Post-Traumatic Growth Inventory-Short (PTGI-S)
The PTGI-S [6] was used to measure the degree of positive change experienced during the COVID-19 pandemic, which has excellent psychometric properties (Cronbach's α = 0.91). The five subscales are (1) relating to others, (2) new possibilities, (3) personal strength, (4) spiritual change, and (5) appreciation of life. Higher scores indicate more significant degrees of change. Questions use a 6-point Likert scale from (1) no change to (6) a high degree of change. Scores at the 60th percentile or higher (≥32) indicate potential personal growth.

The Multidimensional Scale of Perceived Social Support (MSPSS)
The MSPSS [57] was used to measure perceived social support during the COVID-19 pandemic. The scale included 12 items describing perceived support from family, friends, and significant others (e.g., "I can talk about my problems with my family", "My friends really try to help me"). Items were ranked on a 7-point Likert scale, ranging from (1) strongly disagree to (7) strongly agree. Higher scores indicate a higher level of perceived social support. In the present study, the Cronbach's alpha value was 0.80.
Although a part of the subscales presented lower alpha values than conventionally accepted values, it was not totally unexpected. Indeed, in the study by Gosling, Rentfrow and Swann [58] where TIPI was developed and validated, the reported Cronbach's alphas were 0.68 for extraversion, 0.40 for agreeableness, 0.50 for conscientiousness, 0.73 for emotional stability, and 0.45 for openness to experience, which were similar to the present study. Gosling, Rentfrow and Swann [58] concluded that TIPI achieved an adequate level in each of the criteria evaluated: convergent and discriminant validity, test-retest reliability, and patterns of external correlates. In addition, due to the large number of questions measured in this study, the use of the TIPI was strategically chosen in order not to increase the burden of participants in filling out the questionnaires, but to improve the quality of the data received.

Brief COPE Questionnaire
The Brief COPE Questionnaire [60] consisted of 28 items that assessed how participants coped with the stress they faced during the COVID-19 pandemic. The Brief COPE consists of 14 conceptually distinct subscales. Four-point scales were used to measure the extent to which the participants were coping with stress associated with the COVID-19 pandemic, ranging from (1) I haven't been doing this at all to (4) I have been doing this a lot. Based on a four-factor structure [61], we grouped the coping strategies to measure problem-focused coping (active coping and planning; α = 0.84), avoidant coping (behavioral disengagement and denial; α = 0.77), social support coping (emotional support, instrumental support, and venting; α = 0.81), and emotion-focused coping (positive reframing, acceptance; α = 0.76).

Statistical Analysis
All demographic factors were summarized using frequencies and percentages. The relationships between the key variables were assessed using Pearson correlation analysis. Next, mediation analyses were conducted using the AMOS version 26 software. All path coefficients were estimated using the maximum likelihood method based on the multivariate normality of observable variables, and their significance was assessed using bootstrapping with 2000 replications. The coefficient of determination (R 2 ) was computed to assess how well the model explains the outcome. All tests were two-tailed, and a p-value of less than 0.05 was statistically significant.
A post hoc power analysis was performed to evaluate the power of the statistical analysis [63]. Given the final sample size (n = 181), alpha level at 0.05, and an effect size of 0.46, we were able to achieve a post hoc power larger than 0.99, which is greater than the conventional adequacy standard of 0.80.

Results
The descriptive statistics for PTG and its subdomains, demographic characteristics of participants, and the relationship between demographic factors and PTG are shown in Table 1. The sample was predominantly female (70.2%) and students (81.2%), with a mean age of 24.68 years (SD = 5.40). The participants were mainly from China (81.8%). A total of 84.0% of the participants reported living with others, and more than half of the participants reported living in China (61.3%) during the COVID-19 pandemic, followed by 22.1% living in Sweden. For PTG, there was no gender difference in this study (p = 0.92).
The average PTG score was 33.41 (SD = 10.88), and 60.8% participants with scores at the 32 points or higher demonstrated personal growth during COVID-19. As Table 1 shows, amongst PTG subdomains, personal strength was scored the highest by participants (M = 7.02; SD = 2.65) along with relating to others (M = 7.00; SD = 2.53) and appreciation of life (M = 6.81; SD = 2.53).

Mediation Models
A multiple mediation model was constructed to test if the participants' coping strategies mediated between their perceived social support and post-traumatic growth and between their personality traits and post-traumatic growth. The goodness-of-fit assessment of the path model showed that X 2 (20) = 34.25, p = 0.025, X 2 /df = 1.71, RMSEA = 0.06, CFI = 0.98, GFI = 0.98, and SRMR = 0.03, indicating the good model fit of the path model. The model explained 46% of the variance of PTG. Table 3 showed the significant mediation effects, and corresponding paths were shown in Figure 2. Only the significant indirect effects and the relevant direct effects are presented in the Table and Figure for readability. For example, results for social support coping are not presented in the Figure because no main effect and mediating effect of social support coping was found, which was inconsistent with the hypothesis. In addition, openness could not affect PTG directly or indirectly through any coping strategy. However, note that the complete results are available in Table A1 of Appendix A.

Discussion
The purpose of the current study was to identify factors that might predict PTG in response to the COVID-19 pandemic in an effort to find a measure to enhance it. More than half of the participants showed PTG, which confirmed that pandemics can bring about positive outcomes [7], along with traumatic and negative ones [64]. In addition, the which include the results from the variables included in the analysis which, however, were not presented above due to brevity (i.e., emotional stability, openness, and social support coping), please refer to Appendix A. ** = p < 0.01, * = p < 0.05.

Discussion
The purpose of the current study was to identify factors that might predict PTG in response to the COVID-19 pandemic in an effort to find a measure to enhance it. More than half of the participants showed PTG, which confirmed that pandemics can bring about positive outcomes [7], along with traumatic and negative ones [64]. In addition, the current study identified some mechanisms that lie behind post-traumatic growth during the pandemic.
In line with previous research [20,26,65], perceived social support positively influenced PTG. One possible explanation is that high perceived social support can provide a sense of having a safe environment, emphasize feelings of belonging, serve as a buffer against stress, provide new meaning, and generate more positive perceptions that endorse growth [6,8]. Besides, according to the Functional Description Model [6], the mediating effect of coping strategies also explains the relationship between perceived social support and PTG. Perceived social support facilitates cognitive processes, and people use coping strategies to identify positive meanings for personal growth [24]. The participants with high perceived social support in our study used more problem-focused coping and emotion-focused coping and presented higher levels of PTG, supporting the above claims.
The positive effect of extraversion on PTG was observed, consistent with previous studies [21,26,28]. People high in extraversion are fun-loving, active, and optimistic [19], so one possible explanation for the result is that people high in extraversion are more likely to express their emotions and expose themselves to others, which promotes PTG in interpersonal interactions [21]. Another possible explanation is also based on how extroverted persons are more optimistic. Specifically, optimistic individuals tend to focus on the most important matters and reject unachievable goals that are inconsistent with reality, which could lead to PTG [21,66]. Furthermore, people with high extroversion are more likely to use more support-seeking, problem-solving, and cognitive restructuring strategies, and achieve higher levels of PTG [53]; the mediating effects of emotion-focused coping between extraversion and PTG in our study support this explanation.
Positive correlations between conscientiousness and agreeableness and PTG were found, and further analysis revealed that their relationships were mediated by avoidance coping. This suggests that people with low agreeableness or low conscientiousness adopt more avoidance coping, and avoidance coping in turn alleviates stress and promotes growth to some extent [43]. People with low conscientiousness are characterized by low self-regulation, impulsiveness, and undiscipline [59]. People with low agreeableness tend to be manipulative, ruthless, uncooperative, and irritable [67]. Given this backdrop, it is not surprising that people with low conscientiousness or low agreeableness did not proactively deal with traumatic events, but rather take an avoidant approach [53]. It should be noted that some mediating effects were small in the present study and may need to be further validated.
The positive correlation between emotional stability and PTG contradicts some studies [5,33,34], yet it supports others [28]. Our finding indicates that emotionally stable people are able to better handle stressful situations and regulate their emotions. This implies that emotionally stable people may benefit from their emotional stability which protects them from negative effects of stressful events, such as the COVID-19 pandemic.
The most robust predictors of PTG were the use of problem-focused coping, emotionfocused coping and avoidance coping. Coping is accepted as "a transactional process between individuals, the context, and post-trauma outcome" [52] (p. 326). When faced with a stressful event during COVID-19, the participants in our study who adopted problemfocused coping tended to take a positive coping attitude and make a detailed plan to work through the problem to eliminate the stress, which is vital to maintain one's quality of life [38]. Besides, people who adopt emotion-focused coping are more inclined to solve problems emotionally by changing their cognitive processes, reconstructing what happened, and/or adopting an attitude of acceptance to make peace with the situation [38]. These strategies seemed to help the participants in our study reform their views on the COVID-19 pandemic, and consequently facilitate them to overcome COVID-19-related problems [68].
Avoidance coping as a positive predictor of PTG in this study contradicts some studies [38,39,45] but supports the results of others [43,44,46,47]. One explanation is that coping is situation-specific, and is cultural and context-dependent [46]. It has been suggested that avoidance-coping plays an adaptive role as a common response in the early post-traumatic period and promotes PTG [21,46,69]. In addition, an avoidant reaction alleviated the patient's anxiety to a greater extent in a Chinese study [70]. Another explanation is that appropriate avoidance may be beneficial in reducing symptoms of distress and improving patients' quality of life [69]. In the current global pandemic, the general population faces a stressful event beyond one's own control at an individual level. People cannot eradicate the virus, but are exposed to panic and anxiety. Perhaps the only thing people can do in such a situation is to find a way to extricate themselves from the anxiety of the stressful event. Thus, it is possible to get positive change through active distraction [71].
Moreover, researchers have proposed the Janus Face Two-Component model [72], which conceptualizes PTG as both an outcome of trauma and a strategy to relieve emotional distress. The model includes two components of PTG: a functional side and an illusory side. The functional side refers to the positive psychological outcome that results from the trauma, as illustrated in the Tedeschi and Calhoun [6] model. In contrast, the illusory side refers to treating PTG as a strategy or process, rather than an outcome. Some researchers have argued that if avoidance strategies promote PTG, it indicates the illusory side of PTG [43]. The significant effect of avoidance-coping in the present study is in line with this argument.
Social support coping was positively correlated with PTG, but further analysis revealed that social support coping did not significantly predict PTG and there was no mediating effect of social support coping. One explanation is that during the COVID-19 pandemic, people's access to social support was objectively hindered. Participants are not able to entirely rely on their preferred coping strategies for dealing with stress (e.g., socializing with other people, seeking social support) [10]. Another explanation is that people who use social support coping perceive more social support rather than vice versa. Thus, perceived social support might mediate the relationship between social support coping and PTG, rather than social support coping acting as a mediator between perceived social support and PTG. Further investigations are needed to test this speculation.

Implication
To our knowledge, this is the first study that was conducted to examine the associations between social support, personality, coping, and post-traumatic growth specifically in the context of the COVID-19 pandemic. Previous studies have not yet touched upon this kind of pandemic, which interrupts or prevents people from public socialization globally. The current study expanded the scope of research into this new phenomenon. The findings of this study suggest that our previous knowledge on post-traumatic growth, which were generated based on other categories of traumatic experiences, such as cancer, war, and natural disasters, has great potential to be generalizable to a new type of mass trauma brought about by COVID-19. The results highlight the vital role of personal characteristics (e.g., personality traits and coping strategies) and external resources (e.g., social support) in explaining the PTG, and revealed indirect routes that might contribute to PTG during the COVID-19 pandemic. The findings of this study not only supplement the growing body of literature on the psychological consequences of the COVID-19 pandemic, but also contribute to the literature by exploring the mediating role of coping strategies in the relationship between personality and PTC, and between perceived social support and PTG.
The findings have implications for clinical practice, and even informing strategies for public health authorities. It is essential for clinicians to teach individuals how to utilize different coping strategies that are carefully tailored to their level of perceived social support and personality in order to successfully handle their pandemic-related concerns and thoughts. This is in line with the suggestion by Trobst [73] that intervention procedures may be more effective if tailored for individuals based on personality dispositions. For example, individuals scoring low on conscientiousness may benefit from the skill and active distraction, while the outgoing extrovert may respond best to offers of emotional support. In addition, a severe shortage of resources could influence people's access to social support through conventional means, such as social support coping, during the COVID-19 pandemic. It implies the need for a variety of timely psychological support, including telemedicine and informal support groups [74].

Limitations
The present study has some shortcomings that should be acknowledged. The first limitation was related to the research design. The current study adopted a cross-sectional design, which accompanies two drawbacks. First, a cross-sectional design limits our ability to make causal inferences about the observed relationships. Therefore, it is noteworthy that our discussions and conclusions about the directions between the variables were only based on the theoretical conceptions, and were not substantiated by empirical test; thus, it is impossible to conclude from our study that the use of coping strategies lead to PTG. Second, although PTGI-S is psychometrically valid, without a pre-COVID-19 psychological profile, self-reported data from a single time-point may be subject to possible recall bias and social desirability. In order to obtain as much information as possible about the positive changes related to COVID-19 and to partly address the above-mentioned weaknesses, we specifically emphasized that the questions in the survey concerned situations during the COVID-19 period to the participants. However, we cannot be entirely sure that the data represent the actual growth of the participants. Hence, a longitudinal study is needed to enable more rigorous comparisons across time-points.
The second limitation was related to the sampling method. Although the post hoc power analysis showed that the current study obtained an adequate level of power, undeniably, the small sample size and convenient sampling method limited the representativeness of the sample in this study. Lack of randomization or representative samples may have led to a selection effect. That is, it might have been the case where people with high PTG were more willing to participate in the survey, while people with low PTG, who supposedly suffer from mental health issues, were more reluctant to respond to the online survey. The survey was conducted via the Internet, where its users tend to be younger; this might explain the overrepresentation of young people in our sample. The lack of older people in the sample may be particularly noteworthy given that they are more vulnerable to many risks driven by the COVID-19 pandemic. Additionally, most of the participants in this study were living in China, although a separate test only with the participants residing in China (n = 111) yielded similar results to those obtained from the entire sample. These may all lead to limitations in the generalizability of the findings to other similar populations.
The third limitation was the low Cronbach's alpha of some personality traits in the current study which we specified earlier in the methodology section. Again, given the research context, TIPS was a strategic choice, and TIPS is considered as adequate despite its inherent limitation of lower-than-usual Cronbach's alpha values due to its small number of items [58]. However, it is undeniable that some more nuanced details might be captured if a more sophisticated and reliable personality measure is used.
The fourth limitation was that psychopathological conditions were not considered in this study. There were two reasons why psychopathology was not considered. First, unlike many other studies that have examined the negative effect of the COVID-19 pandemic on mental health issues [75], our aim was to clarify the relationship between PTG and the relevant factors. Second, it has been suggested that the general population may experience less fear and psychopathology due to lower morbidity and mortality from COVID-19 than high-risk populations, such as health-care workers [75]. However, the absence of information on the psychopathology of the participants indeed limited our potential to either control for or investigate the potential roles that psychopathology might have played in the relationship between PTG and related factors, which deserves further exploration.
The last limitation was that we did not consider the participants' country of origin, which may have an impact on PTG. An individual's religiosity and spirituality are shaped by the context in which they were grown, and many studies have found a clear relationship between religiosity and PTG [76]. Additionally, research has indicated that individuals' cognitive strategies are influenced by their cultural background (e.g., religiosity and spirituality) [77]. Although we had our reasons to collect information on the participants' country of residence during the COVID-19 pandemic, the lack of information on the participants' country of origin undeniably limits our interpretation of the relationship between PTG and related factors.

Further Research
This study also provides directions for future research. First, future studies can adopt longitudinal designs to fully disentangle the underlying causality among the variables. Second, in addition to assessment by self-reporting, further research should consider clinical and observational data, or means of neuroscience, to fully understand the mechanisms behind PTG. Third, future efforts can be made to ensure to recruit more representative samples, including various age groups and different cultures, to reduce any biases that can be derived from selection effects. This would help to fill the gap that the current study leaves to the literature on the PTG of the general population. Fourth, cultural differences in PTG are also worthy of further investigation. Kashyap and Hussain [78] stated that individuals' cognitive strategies and growth processes are influenced by their culture, so it is crucial to research PTG within the framework of the individual's culture. In this study, the majority of participants were from China. Therefore, our findings illustrate the mechanisms of PTG in the context of the COVID-19 pandemic, mainly from a collectivist culture [79]. PTG in other cultural contexts (e.g., individualism) needs further study. Finally, as mentioned in the discussion, the relationship between avoidance-coping and PTG, and the possibility that perceived social support may mediate the relationship between social support coping and PTG, deserves further investigation.

Conclusions
In summary, the current study aimed to identify factors and mechanisms that might enhance PTG during the COVID-19 pandemic. Most people experience post-traumatic growth during the COVID-19 pandemic period. As expected, our findings indicate that perceived social support, some personality traits (extraversion, agreeableness, conscientiousness, and emotional stability), and some coping strategies (problem-focused coping, emotion-focused coping, and social support coping) are positively correlated with PTG during the pandemic. In addition, the association between perceived social support, personality factors (extraver-sion, agreeableness, and conscientiousness), and PTG are mediated by coping strategies (problem-focused coping, emotion-focused coping, and avoidance coping).

The current study did not fall under the requirements of the Ethical Review Act given, among others, its nature to ensure a complete anonymity and confidentiality of the research participants as well as its nature being non-harmful and non-influential (neither physically nor mentally) to the research participants. Therefore, the current study was considered as non-applicable to an ethical review and approval. However, we state that the current study was conducted according to the guidelines of the Declaration of Helsinki.
