Background: Perceived stigma has greatly influenced the life quality of the COVID-19 patients who recovered and were discharged (RD hereafter). It is essential to understand COVID-19 stigma of RD and its related risk factors. The current study aims to identify the characteristics of perceived COVID-19 stigma in RD using latent profile analysis (LPA), to explore its psycho-social influencing factors, and to determine the cut-off point of the stigma scale using receiver operating characteristic (ROC) analysis.
Methods: A cross-sectional study was conducted among COVID-19 RD in 13 communities in Jianghan District, Wuhan City, Hubei Province, China from June 10 to July 25, 2021, enrolling total 1,297 participants. Data were collected on demographic characteristics, COVID-19 perceived stigma, post-traumatic stress disorder (PTSD), anxiety, depression, sleep disorder, fatigue, resilience, social support, and peace of mind. LPA was performed to identify different profiles of perceived COVID-19 stigma level. Univariate analysis and multinominal logistic regression analysis were conducted to explore the influencing factors in different profiles. ROC analyses was carried out to identify the cut-off value of perceived stigma.
Results: Among the participants, three profiles of perceived stigma were identified: “low perceived COVID-19 stigma” (12.8%), “moderate perceived COVID-19 stigma” (51.1%), and “severe perceived COVID-19 stigma” (36.1%). Multinominal logistic regression analysis revealed that older age, living with other people, anxiety, and sleep disorder were positively associated with moderate perceived COVID-19 stigma, while higher educational level was negatively associated with moderate perceived COVID-19 stigma. Female, older age, living with other people, anxiety, and sleep disorder were positively associated with severe perceived COVID-19 stigma, while higher educational level, social support, and peace of mind were negatively associated with severe perceived COVID-19 stigma. ROC curve of the Short Version of COVID-19 Stigma Scale (CSS-S) for screening perceived COVID-19 stigma showed that the optimal cut-off value was ≥ 20.
Conclusion: The study focuses on the issue of perceived COVID-19 stigma and its psycho-socio influencing factors. It provides evidence for implementing relevant psychological interventions to COVID-19 RD.
1. Introduction
COVID-19 has emerged as a global health emergency and posed a great threat to almost all countries and regions (1). It affects all segments of the population, especially the patients of COVID-19 (2). The impact is far beyond merely physical concerns. Previous studies have shown that the pandemic has led to psychological problems among patients, healthcare workers, and other caregivers (3, 4). Patients infected with COVID-19 not only suffered from illness, but also had mental health problems due to viral infection and worries about after-effects (5). Perceived stigma is prevalent among COVID-19 survivors and healthcare workers in COVID-19 designated hospitals, which has an interrelated bearing on their mental health (6, 7).
In post pandemic era, most patients of COVID-19 have been discharged (8). The mental health of those who had recovered from COVID-19 and been discharged from hospital (RD hereafter) deserve more attention during their rehabilitation (9). These patients were isolated during treatment and had limited freedom and communication with the outside world (10). Thus, their negative emotions cannot be alleviated in a short period of time. RD may have a more serious sense of loneliness and repression, as well as a higher level of psychological pressure (11). In the aftermath and the long-covid period, they may experience depression, anxiety, fatigue, post-traumatic stress disorder, and neuropsychiatric syndromes (12–14). Poor mental health condition will impact one’s social behaviors and cognitive functions. As a result, RD’s mental health should be attached much importance.
RD’s mental health condition might affect their perceived COVID-19 stigma (15). Perceived stigma is one’s personal feelings about the stressors and his projection of the feelings on others (16). From the patient’s perspective, they might feel being stigmatized if their mental health condition was poor. COVID-19 RD are at high risk of PTSD, partly because of their near death experience, delirium, and ICU-related trauma during the COVID-19 experience (17, 18). They might have uncontrollable thoughts about the experience and their image in others’ mind, which would increase their perceived stigma. Perceived stigma might also in turn predict PTSD (19). Depression is another prevalent mental issue among COVID-19 RD (20). RD with depressive symptoms might be more sensitive and pessimistic to the negative attitudes from the community, which makes them feel more stigmatized emotions (21). Besides, to contain the spread, patients are required to stay in close isolation during treatment and reduce their movement after discharge, which may lead to feelings of loneliness and fear of discrimination, thus increasing their perceived stigma (22). Peace of mind is important for them to manage stressful situations, as well as avoid the irresistible but unwanted impulses (23). Resilience is not a linear path toward happiness, but a combination of behaviors that encourages individuals and communities to persevere and move forward confronting difficult situations (24, 25). Higher level of resilience might decrease the risk of developing psychological distress, and suppress suicidal thoughts and insomnia (26, 27). Resilience might be influenced by job stress, perceived stress, and mindfulness, and be promoted by brief resilience interventions based on positive psychology (28–30). Thus, with higher level of peace of mind and resilience, patients will control their emotions better and be less sensitive to the negative attitudes from others, which might result in lower sense of perceived stigma. From the society’s perspective, low perceived social support may also lead to perceived stigma among COVID-19 RD (31). Perceived stigma might in turn increase the mental problems among RD and be detrimental to their mental health recovery (32). Therefore, the stigma among COVID-19 RD may have a certain impact on the whole population.
The perceived COVID-19 stigma in RD could be evaluated by a modified 12-item HIV stigma scale, which contains 4 sub-scales to measure personalized stigma, disclosure concerns, concerns about public attitudes, and negative self-image (33). However, this scale has no cut-off point, which makes it hard to precisely evaluate the stigma among RD. Clinical psychiatric interviews are usually regarded as the gold standard for diagnosis and the criterion for determining cut-off points of screening tools, However, the identification and diagnosis of cases with perceived COVID-19 stigma has not reached a consensus. Additionally, the characteristics and prevalence of perceived COVID-19 stigma among RD and its psycho-social influencing factors remain elusive. Currently, most previous studies focused on the recursive effect of perceived stigma on mental health without considering the possible vicious circle between mental health and perceived stigma among RD. While according to the theory of socio-ecological model, one is not a passive recipient of life events, but a key role in constructing and modifying the living system (34). It is therefore important to explore the influencing factors of perceived COVID-19 stigma among RD. The specific objectives of current study are to identify the characteristics of perceived COVID-19 stigma in RD using latent profile analysis (LPA); to explore the psycho-social influencing factors of perceived COVID-19 stigma in RD; and to determine the cut-off point of the stigma scale using ROC analysis for further evaluation and application, which may help healthcare professions and policymakers to deal with the increasing stigma and control the pandemic effectively.
2. Methods
2.1. Study design and participants
The cross-sectional study was carried out among previously-infected COVID-19 patients in Jianghan District (Wuhan, China) from June 10 to July 25, 2021. Extracted from the electronic medical records of the Jianghan District Health Bureau, a total of 3,059 COVID-19 patients met the inclusion criteria and were eligible for the study, for they were infected with the original SARS-Cov-2 strain and were diagnosed between December 10, 2019 and April 20, 2020. When they were receiving clinical re-examination, 1,601 COVID-19 survivors were invited to complete a questionnaire survey on their mental health status, and 1,541 of them who finished the survey were included in the study. All investigators and support staff in this study were trained according to the same protocol and required to have an educational background in medicine or public health. From June to July 2021, the online structured questionnaire was distributed to those who had a history of COVID-19 infection and had been discharged. All participants’ digital informed consent was obtained to ensure their voluntary participation. An online survey platform Redcap was used to disseminate the self-administered electronic questionnaires and digital consent to the target population. The study was approved by the Ethics Review Board of the Institute of Pathogen Biology, Chinese Academy of Medical Sciences (IPB-2020-22), and the Research Ethics Committee of the hospital (2021001, 20210208). The participants had to meet the following criteria: (1) over the age of 18; (2) a history of COVID-19 hospitalization; (3) proficiency in Chinese; (4) able to independently complete scale assessments with the assistance of the researchers; (5) had a mobile communication device like a smartphone and a WeChat account; (6) able to access the Internet with mobile equipment at any time; (7) had not received PTSD, depression, or anxiety interventions within 1 month before his or her enrollment in the study. Those who met any of the following criteria were excluded: (1) had serious cognitive impairment; (2) had serious heart, brain, lung, kidney, liver, and other medical diseases or tumors; (3) found it difficult to complete the questionnaire study. In total, of the 1,541 participants who completed the questionnaire, 1,297 participants were included in the final analysis based on the criteria above.
2.2. Measures
2.2.1. Demographic characteristics
Demographic characteristics, including gender, age, region, marital status, etc., and items on COVID-19 infection, such as clinical classification of COVID-19 in patients and perceived mental health status during hospitalization, were collected.
2.2.2. Stigma
The Short Version of COVID-19 Stigma Scale (CSS-S) is a 12-item scale that is employed for evaluating the perceived stigma of patients of COVID-19 during the past 2 weeks (33). The scale was reviewed by several experts in the field and was approved to use in this population. Each item is scored on a Likert scale of 1–4. Higher total scores indicate greater stigmatization. In this study, the Cronbach’s alpha of the instrument was 0.936.
2.2.3. Post-traumatic stress disorder
The Impact of Events Scale-Revised (IES-R) is a 22-item scale aimed at screening posttraumatic stress symptoms in adults or older people. The items of this instrument are rated on a 5-point Likert scale from 0 to 4 (35, 36). The IES-R contains three dimensions measuring intrusion, avoidance, and hyperarousal. Respondents rate their degree of distress during the past 7 days after they have identified a specific stressful life event that occurred to them. A total score equal to or above 35 can be regarded as positive PTSD symptoms. This instrument has been proven valid and reliable among Chinese COVID-19 patients (37). In this study, the Cronbach’s alpha of the instrument was 0.965.
2.2.4. Anxiety
The Generalized Anxiety Disorder Questionnaire (GAD-7) consists of 7 items that are rated on a 4-point Likert scale from 0 to 3. It was developed for measuring the severity of generalized anxiety symptoms during the past 2 weeks (38). The scores of the instrument range from 0 to 21. A cutoff score of ≥ 5 is recommended for considering significant anxiety symptoms. This instrument has demonstrated to be reliable and valid among the Chinese population (39, 40). In this study, the Cronbach’s alpha of the instrument was 0.951.
2.2.5. Depression
The Patient Health Questionnaire (PHQ-9) is a 9-item questionnaire that is used for screening and monitoring depression of varying degrees of severity during the past 2 weeks (41). The items of the PHQ-9 are rated on a 4-point Likert scale ranging from 0 to 3. The total score is utilized to assess the degree of depression of participants, with scores of ≥ 5 indicating depression. This instrument has been validated among various Chinese populations (42, 43). In this study, the Cronbach’s alpha of the instrument was 0.914.
2.2.6. Sleep disorder
The Pittsburgh Sleep Quality Index (PSQI) consists of 18 items and is used to measure an individual’s quality of sleep during the past 2 weeks (44). It contains seven components including subjective sleep quality, sleep latency, sleep duration, sleep efficiency, sleep disturbance, use of sleep medication, and daytime dysfunction, and each component is a 4-point Likert scaled from 0 = no difficulty to 3 = severe difficulty. The total scores range from 0 to 21 and a cutoff score of ≥ 6 is recommended for considering certain sleep disorders (45). This instrument has been validated among Chinese population (46). In this study, the Cronbach’s alpha of the instrument was 0.784.
2.2.7. Fatigue
The Fatigue Scale-14 (FS-14) is a 14-item scale aiming at measuring the severity of fatigue during the past 2 weeks (47). The items of this instrument are rated on a 2-point scale of 0–1. The FS-14 contains two dimensions measuring physical fatigue and mental fatigue, respectively. Higher total scores of the 14 items indicate a higher level of fatigue. This instrument has been proved valid and reliable among Chinese (48). In this study, the Cronbach’s alpha of the instrument was 0.845.
2.2.8. Resilience
The Resilience Style Questionnaire (RSQ) consists of 16 items that are rated on a 5-point Likert scaled from 1 to 5. It is used to measure the level of an individual’s resilience during the past 2 weeks (49). Higher total scores of the 16 items indicate a greater ability to recover from negative events. This instrument was developed and validated among the Chinese rural left-behind adolescents and non-local medical workers (50, 51). In this study, the Cronbach’s alpha of the instrument was 0.975.
2.2.9. Social support
The level of perceived social support of the participants was measured by two items including emotional support and material support during the past 2 weeks (52). The items were: (1) “How much support can you obtain from family/friends/colleagues when you need to talk or to obtain emotional support?” and (2) “How much support can you obtain from family/friends/colleagues when you need material support (e.g., financial help)?” and each item was 11-point Likert scaled from 0 to 10. In this study, the Cronbach’s alpha of the instrument was 0.819.
2.2.10. Peace of mind
The Peace of Mind Scale (PoM) comprises a total of 7 items rated on a 5-point scale ranging from 1 (“not at all”) to 5 (“all of the time”) and is used for measuring the peace of mind during the past 2 weeks (53). Higher total scores indicate a more peaceful mind. This instrument has been validated among Chinese population (53). In this study, the Cronbach’s alpha of the instrument was 0.874.
2.3. Statistical analysis
Descriptive analyses were performed to describe the participants’ demographic characteristics, clinical characteristics, the condition of perceived stigma, and potential influencing factors.
In the absence of an accurate and precise reference standard, LPA has been widely employed to identify the symptom characteristics and to further calculate and determine optimal cut-off points of assessment instruments (54–56). LPA is a person-centered statistical method that employs latent profile model (LPM) to divide population into multiple profiles, and it focuses on identifying latent subpopulations within a population based on a set of continuous variables (57–59). Despite the possible arbitrariness for LPA in determining the number of class members due to its semi-subjective properties, the misclassification rate is relatively low, and it could produce more reasonable results compared with some other classification approaches (60–62). Generally, in LPA, individuals assigned to the latent profile that represents the lowest level of symptoms or risks are regarded as “non-cases,” and others are considered “cases” (56). Hence, LPA was conducted to identify the characteristics of perceived COVID-19 stigma among RD. Robust maximum likelihood (MLR) estimation was employed to estimate the parameters. The Lo–Mendell–Rubin (LMR) and the bootstrap likelihood ratio test (BLRT) were performed to compare the model fit improvement between models with k classes and k-1 classes, significant p values indicated a better model fit with k classes. The optimal number of classes was evaluated by the entropy, Akaike Information Criterion (AIC), Bayesian Information Criterion (BIC), the adjusted Bayesian Information Criterion (aBIC), and the interpretability and definition of classifications, where an entropy value≥0.80 represented adequate quality of classification, lower AIC, BIC, and aBIC values indicate better model fit, and the “turning point” of the scree plot for the aBIC could suggest an appropriate number of classes.
After the selection of optimal model and definition of classifications, Chi-square began with the full set of demographic and clinical characteristics, PTSD, anxiety, depression, sleep disorder, fatigue, resilience, social support, and peace of mind, to evaluate their associations with different characteristics of perceived COVID-19 stigma. Statistically significant variables (p ≤ 0.20) in the univariate analysis were further used for stepwise multinomial logistic regression analysis. Adjusted odds ratio (AOR) and the corresponding 95% confidence intervals (95% CI) were calculated to assess the regression model results.
Receiver operating characteristic (ROC) analysis was conducted to determine the optimal cut-off value for the CSS-S. The area under the ROC curve (AUC), sensitivity, specificity, and Youden’s index value were employed to evaluate the performance of classifiers, and Youden’s index value was used to identify the optimal cut-off value. SAS9.4 and Mplus8.3 were utilized to conduct all the analyses with level of significance determined at a 0.05 value of p.
3. Results
3.1. Demographic characteristics
Among the 1,541 people who finished the survey questions, 1,297 questionnaires were enrolled in the data analysis. As illustrated in Table 1, over half of the participants were male (n = 563, 56.6%) and were less than or equal to 60 years old (n = 683, 52.7%). The majority of the participants were from urban areas (n = 1,136, 87.6%) and married (n = 1,105, 85.2%). Most of the participants had an income for 2020 less than 60,000 China Yuan(CNY, 1 CNY equals 0.14 USD on 2022.12.31; n = 805, 62.1%), and had an education level as senior high school or below (n = 921, 71%). A small percentage of participants lived alone (n = 158, 12.2%), used alcohol no less than 2 times per week (n = 117, 9%), and were current smokers (n = 161, 12.4%). The COVID-19 patients were clinically classified into four categories: asymptomatic (n = 60, 4.6%), mild (n = 927, 71.5%), moderate (n = 132, 10.2%), critically severe (n = 178, 13.7%). A significant proportion of the participants had no experience at ICU (n = 1,250, 96.4%), had never received psychological or emotional counseling during hospitalization (n = 1,225, 94.4%), and had never received psychological or emotional counseling before infection (n = 1,169, 90.1%). Just under a half of participants stayed over 20 days in hospital (n = 611, 47.1%), and had no complication (n = 530, 40.9%). Most of the patients perceived good (n = 736, 56.7%) or moderate (n = 247, 19%) mental health status during hospitalization.
Table 1. Demographic characteristics of the participants.
3.2. Stigma and related psychological factors
The 12-item CSS-S’s total scores range from 12 to 48 with higher scores indicating a more stigmatizing attitude. The mean score in this study was 28.04 (SD = 7.33). The mean scores of fatigue, peace of mind, resilience, and social support were 6.38 (SD = 4.04), 24.70 (SD = 5.99), 56.82 (SD = 14.04), 14.25 (SD = 5.18), respectively. The prevalence of PTSD, anxiety, depression, and sleep disorder were 16.5, 28.8, 37.9, and 47.1%, respectively (Table 2).
Table 2. Descriptive statistics for CSS-S, FS-14, PoM, RSQ, social support, IES-R, GAD-7, PHQ-9 and PSQI.
3.3. Latent profile analysis
Latent profile models (LPA) with one-to-five-class solutions were specified, and the fit indices of the 5 models are displayed in Table 3. The entropies of all classifications were above 0.9. The LMR and BLRT test were all statistically significant. The AIC, BIC and aBIC decreased with the increase of class number, and the scree plot of aBIC flattened out after the 3-class model (see Figure 1). Taken together, considering the model fit, parsimoniousness, and interpretability of the classes, the 3-class model was selected as the optimal model for the current sample, the distribution and conditional means of items of CSS-S on each class in the 3-class model are illustrated in Figure 2 and Table 4. In the 3-class model, the average latent class probabilities for most likely latent class membership (0.978, 0.977, and 0.972) demonstrate reasonable classification and good distinction (see Table 5). Given the conditional means of items on each class, we define Class1 (n = 166, 12.8%) as “low perceived COVID-19 stigma” group, Class2 (n = 663, 51.1%) as “moderate perceived COVID-19 stigma” group, and Class3 (n = 468, 36.1%) as “severe perceived COVID-19 stigma.”

3.4. Influencing factors of perceived COVID-19 stigma of RD
The result of univariate analysis showed that female (χ2 = 21.999, p < 0.001), older age (χ2 = 45.595, p < 0.001), being married (χ2 = 4.401, p = 0.111), low family income (χ2 = 23.261, p < 0.001), living with other people (χ2 = 7.456, p = 0.024), low education level (χ2 = 61.653, p < 0.001), having complication (χ2 = 10.117, p = 0.006), perceiving worse mental health status during hospitalization (χ2 = 48.489, p < 0.001), PTSD (χ2 = 73.360, p < 0.001), anxiety (χ2 = 74.878, p < 0.001), depression (χ2 = 70.081, p < 0.001), sleep disorder (χ2 = 70.875, p < 0.001), and fatigue (F = 21.220, p < 0.001) were positively associated with perceived COVID-19 stigma, while resilience (F = 22.030, p < 0.001), social support (F = 25.070, p < 0.001), and peace of mind (F = 39.130, p < 0.001) were negatively associated with perceived COVID-19 stigma among RD (see Table 6). These variables were further employed in stepwise multinomial logistic regression analysis with the “low perceived COVID-19 stigma” group as a reference. The result of stepwise multinomial logistic regression analysis showed that older age (AOR = 1.753, p = 0.004), living with other people (AOR = 2.152, p = 0.003), anxiety (AOR = 2.444, p = 0.004), and sleep disorder (AOR = 1.921, p = 0.002) were positively associated with moderate perceived COVID-19 stigma, while higher educational level (AOR = 0.624, p = 0.012) was negatively associated with moderate perceived COVID-19 stigma; Female (AOR = 1.674, p = 0.011), older age (AOR = 3.046, p < 0.001), living with other people (AOR = 2.037, p = 0.011), anxiety (AOR = 2.813, p = 0.001), and sleep disorder (AOR = 2.628, p < 0.001) were positively associated with severe perceived COVID-19 stigma, while higher educational level (AOR = 0.340, p < 0.001), social support (AOR = 0.953, p = 0.021), and peace of mind (AOR = 0.951, p = 0.008) were negatively associated with severe perceived COVID-19 stigma among RD (Table 7).

3.5. Receiver operating characteristic analysis
To identify the optimal cut-off value of CSS-S for screening perceived COVID-19 stigma among RD, participants assigned to the “low perceived COVID-19 stigma” group in LPA were defined as “non-cases” (i.e., no stigma), and those assigned in “moderate perceived COVID-19 stigma” and “severe perceived COVID-19 stigma” groups were defined as “cases” (i.e., probable stigma). The ROC curve was then plotted for the total score of CSS-S using the binary outcome, with an AUC value of 99.96% (p < 0.001), indicating a good predictive capacity for perceived COVID-19 stigma (see Figure 3). The diagnostic criteria and indices are illustrated in Table 8. The optimal cut-off value was ≥ 20, where the sensitivity, specificity, and Youden’s index value were 0.996, 0.982, and 0.978, respectively.

4. Discussion
The cross-sectional study employs LPA to assess the characteristics of perceived COVID-19 stigma among RD and analyzes its psycho-socio contributing factors. Perceived stigma of RD was divided into three categories in this study. We measured the demographic characteristics and some possible psychological predictors of perceived COVID-19 stigma. Generally, older age, living with other people, anxiety, and sleep disorder were positively associated with moderate perceived COVID-19 stigma, while higher educational level was negatively associated with moderate perceived COVID-19 stigma; female, older age, living with other people, anxiety, and sleep disorder were positively associated with severe perceived COVID-19 stigma, while higher educational level, social support, and peace of mind were negatively associated with severe perceived COVID-19 stigma among RD. The cut-off point of the stigma scale was determined at 20 using ROC analysis.
This study classified COVID-19 RD into three groups according to the stigma level: “low perceived COVID-19 stigma,” “moderate perceived COVID-19 stigma,” and “severe perceived COVID-19 stigma” group. Only 12.8% of RD were categorized into the “low perceived COVID-19 stigma” group, which indicated the lowest levels of stigma and reported the lowest level of psychological risk factors. The majority belonged to the “moderate perceived COVID-19 stigma” (51.1%).
Compared with the “low perceived COVID-19 stigma” group, anxiety and sleep disorder were positively associated with moderate perceived stigma. Similar to previously published studies, anxiety was a major risk factor for stigma. In a study that evaluated the depression and anxiety symptoms among 174 patients who recovered from symptomatic COVID-19 infection in Saudi Arabia, the stigma scores were significantly associated with higher scores on anxiety (63). Some other studies on people living with epilepsy, dementia, and cancer patients also demonstrated that anxiety is one of the psychosocial determinants of perceived stigma (64–66). Therefore, mitigating the anxiety symptoms is essential to decrease the stigma among RD. Emotional regulation, mindfulness, and experiential techniques are possible solutions to improve social anxiety disorder symptoms (67). RD could also try exercise, yoga, and meditation, which were proven to have modest positive effect on assisting their anxiety alleviation (68). Hospitals and communities should assess the anxiety level of COVID-19 RD to detect anxiety as early as possible. For RD with anxiety symptoms, the community should provide them with knowledge and stress coping strategies, and provide training to help them manage emotions. Psychological interventions like mindfulness-based therapy could be implemented by government or community to alleviate anxiety symptoms (69). The society should be less hostile to RD. It is necessary for social media to refute false information, strengthen the information guidance of social media, and output positive information, so as to avoid the anxiety mood in origin.
Our study also found that sleep disorders is a determinant of moderate perceived stigma in RD. Previous studies showed that 29.5% of the COVID-19 hospitalized patients had sleep disorders (70). Poor sleep quality was associated with stigma (71). Cognitive behavior therapy is aimed at treating insomnia by avoiding behaviors and thoughts that might develop into sleep disorders (72). RD with sleep disorders could use this method on their own to improve their sleep quality. Effective programs based on the therapy could also be embedded in smartphones to assist their sleep promotion process (73). In addition, progressive muscular relaxation is an effective way to help COVID-19 patients feel less anxious and have better quality sleep (74).
The “severe perceived COVID-19 stigma” group reported three more risk factors compared with “moderate perceived COVID-19 stigma” group, including female gender, insufficient social support and peace of mind. Female gender is a risk factor of “long-covid” syndrome and tend to have a higher proportion of physical and psychological symptoms than male (75). Because of the more severe illness and torment they suffered, they might find it difficult to maintain a good mentality toward the stigmatized attitudes. A low perceived level of social support prevailed during the pandemic due to the shutdown of many places, like schools, markets, and workplaces to avoid transmission of the virus (76). RD facing such conditions may arouse a sense of isolation and vulnerability, which would cause severe stigma. Perceived social support and use of adaptive coping strategies were found to affect individuals’ psychological adjustment and resilience (77). Interventions like in-person interview, supportive psychotherapy, and positive attention would improve their social support and could be considered widely promoted (78). Peace of mind might increase one’s self awareness and attitude toward the surroundings, and indirectly reduce the sense of being stigmatized. A previous study on female patients with schizophrenia also identified that enhancing peace of mind will help reduce stigma level (79).
Our study determined 20 as the cut-off score for CSS-S by LPA and ROC analysis, which may guide future epidemiological studies on COVID-19 stigma. The cut-off value is instructive for clinical practice in COVID-19 RD mental health promotion. Hospitals are suggested to collect stigma information of discharged patients and carry out relevant psychological intervention for patients whose scores exceed 20.
Although our team have analyzed the same population in advance and explored the prevalence and influencing factors of anxiety and depression in RD (80), a further analysis in this study provided insightful observations from a different perspective. This study enriched our knowledge on the association between mental health and perceived stigma among RD, and provided possible suggestions for the authorities and the society to reduce perceived COVID-19 stigma in the future. However, it has several limitations. First, this cross-sectional study has its inherent limitations, for it contains no dimension of time to support a causal relationship. Second, the study was conducted more than 18 months after the COVID-19 patients were discharged, which may cause recall bias. Third, convenience sampling may decrease the representativeness of the population. Fourth, stigma contains two factors, namely “public stigma” and “self-perceived stigma.” In this study, we only mention the latter. Further studies should measure stigma more comprehensively in a representative sample.
5. Conclusion
This study provides an insightful result of the prevalence and influencing factors of perceived stigma among RD in Wuhan. Stigma among COVID-19 RD could be divided into 3 groups: “low perceived COVID-19 stigma,” “moderate perceived COVID-19 stigma,” and “severe perceived COVID-19 stigma” group. Based on the cut-off value we explored, the high proportion of perceived stigma level highlights the importance of solving the stigma and discrimination problem, for its impact on personal and community well-being. Therefore, it is essential to mitigate the psychological problems and reduce the perceived stigma level of RD as part of the response toward the COVID-19 pandemic. Psychological interventions on anxiety, sleep disorder, and social support are suggested to alleviate mental health problems and stigma among this population. Additionally, this study discovered the precise cut-off value for CSS-S, which provides a valuable tool for screening perceived stigma among future COVID-19 patients and can be used to identify the patients in noosed of tailored interventions.
