Background.

The study aims to understanding the levels of mental health literacy among residents of Guangdong Province, the first major province in China, and its influencing factors is crucial. Such understanding will serve as a solid foundation for mental health promotion initiatives and enhancing the overall mental health literacy levels among residents across the province.

Method

A multi-stage stratified equal-volume random sampling method was adopted in October-December 2022 to select permanent residents aged 18 years and above in Guangdong Province for the questionnaire survey, which consisted of a general demographic information questionnaire and a national mental health literacy questionnaire. Rao-Scott χ test with correction based on sampling design, independent samples t-test and binary multivariate logistic regression analysis were performed.

Results

A total of 51744 individuals completed the questionnaire, including 31822 (61.4%) urban residents and 19200 (38.6%) rural residents. The rate of achievement of mental health literacy was 13.6% among urban residents, which was significantly higher compared to the rate of 8.6% among rural residents. Logistic regression analysis showed that being female, having an education level of 12 years or higher, being mental worker, being a retiree, having a higher monthly household income, maintaining a regular diet, and using electronic products for 2–6 hours per day were all protective factors for mental health literacy attainment in urban residents, while having chronic diseases, being a smoker, having a history of drinking, and being were identified as risk factors in urban residents. Among in rural residents, being married, being younger, having an education level of 12 years or higher, being mental worker and using electronic products for 2–6 hours per day, maintaining a regular diet, and engaging in regular exercise were protective factors for achieving mental health literacy. Additionally, previous smoking was identified as a risk factor.

Conclusion

The study revealed a low level of mental health literacy among urban and rural residents of Guangdong Province, with a significant disparity between the two areas. These findings highlight the need for continuing efforts to increase the dissemination of mental health knowledge in rural communities and improve levels of mental health literacy.

cross-sectional studies

Mental health literacy, which refers to the understanding and awareness that enable individuals to recognize, handle, or prevent mental illnesses, encompasses the integration of knowledge, skills, and attitudes for the promotion and maintenance of mental well-being[1].

Individuals with a high level of psychological literacy are better equipped to identify psychological disorders accurately, actively seek mental health knowledge, and willingly seek help from mental health professionals[2–4]. Furthermore, they adopt a scientific approach to maintaining and promoting mental health, ultimately benefiting not only themselves but also those around them[5]. Mental health literacy is recognized as a crucial component of overall health literacy, directly impacting an individual's mental well-being[6, 7]. Consequently, numerous studies have been conducted to assess mental health literacy levels, with findings consistently revealing higher levels in developed countries[8–10]. Furthermore, interventions aimed at improving mental health literacy have been successful in these countries[11–13].

China, as a developing country, is undergoing a rapid economic and social transition, presenting new challenges for mental health maintenance and promotion. On the other hand, there are fewer psychiatrists than in the world's middle- and high-income countries[14]. According to a recent largescale survey, the prevalence of mental illness among adolescents aged 6 to 16 is 17.5%[15], and the elderly population is also facing a serious mental health crisis, with 1/5 of patients over 65 years of age meeting the diagnosis of depressive disorder[16]. However, another meta-analysis discovered that the identification rate of depression and anxiety disorders in China is less than 30%. Additionally, only less than 40% of the population seeks professional psychological help for mental health issues, while over 60% consider pharmaceutical treatment harmful[17].

Existing literature suggests that improving mental health outcomes is contingent upon increasing the level of mental health literacy[18, 19]. Despite this, studies on mental health literacy in China are still in their infancy, predominantly focusing on knowledge levels and attitudes towards mental health among various populations. There is a lack of comprehensive research examining multiple aspects of mental health literacy and conducting surveys with large sample sizes. On the contrary, previous research on mental health literacy has predominantly concentrated on college students and adolescents, with fewer investigations conducted among the general population residing in urban and rural areas[20–22]. Thus, this study aims to explore the different components of mental health literacy (such as mental health knowledge, positive mindset, mental health information acquisition, mental health awareness, recognition of psychological illness, attitudes towards seeking professional help, and coping with psychological distress) among Chinese adults and identify their influencing factors. We anticipate that the findings from this study will provide valuable insights into the determinants of mental health literacy, assisting policymakers in making informed decisions when formulating mental health policies and plans, ultimately benefiting the mental health of the Chinese population.

Subjects

Permanent residents of Guangdong Province, China, aged 18 or above (born before September 1, 2004 and have resided in Guangdong Province, China, for at least 6 months).

Sampling principles

In order to ensure the representativeness of the survey sample within the regional population, a random sampling technique with equal volume of multistage stratification was employed. This approach took into account the varying economic levels across different regions, the need for consistent geographical distribution coverage, as well as the practical feasibility of conducting the survey. The survey method is based on a targeted and centralized survey, supplemented by a household survey. The survey period is October-December 2022.

Sample size estimation and allocation

Based on the complex sampling design, the sample size estimation formula was used as follows: where the design efficiency def was set at 2.0, with a confidence level α of 95% (two-sided). Considering the estimates of mental health literacy levels of adult residents of Guangdong Province reported by the results of the 2021 Guangdong adult residents' mental health survey, P was found to be 12.1%. The allowable error, d, was taken as 0.2p. Using the above parameter values, the minimum sample size was calculated to be 1395 people. In consideration of an expected response rate of approximately 75.0% and a planned sample size of approximately 1860, the sample size was rounded up to 2000 people. Additionally, the sample was stratified by prefecture-level municipality, allowing it to represent the situation at each prefecture level. The minimum sample size for this stratification was 42,000 people, covering 21 prefecture-level municipalities across the province.

Sampling method

Stage 1 Extraction districts (prefectures/municipalities): 21 prefecture-level municipalities across the province were included, and 3 districts (prefectures/municipalities) were randomly selected from each prefecture-level municipality.

The second stage sampled streets/townships: 3 streets/townships were randomly sampled from each sample area (county/city).

Phase III sampling of the house (Village) Commission: an additional 2 house (Village) boards were sampled from each sampled street/township. In the fourth stage, surveyed households were sampled with respondents: for each sampling house (Village) board, 111–112 households were sampled using a systematic sampling method (e.g., starting point and spacing determined by gate number). Additionally, for each household, 1 person was randomly sampled (using either a draw method or the nearest birth date within a 15-day range, see Supplement Fig. 1).

In the third stage, each selected district and county was categorized into urban and rural areas, as defined by the National Bureau of Statistics of China.

Survey instruments

The National Mental Health Literacy Questionnaire (NMHLQ) is the designated questionnaire for monitoring the indicators of the National Health Commission of the People's Republic of China's "Mental Health Promotion Action". It consists of three parts: judgment questions, self-assessment questions, and case questions.

(1) The judgment question mainly aims to gauge one's level of mental health knowledge. It is scored out of a total of 20 points, with 0 points awarded for unanswered questions or choosing not to respond. Each correctly answered question earns 5 points. The overall score ranges from 0 to 100 points, with meeting a score greater than 80 indicating proficiency.

(2) The self-assessment questions primarily focused on evaluating attitudes towards mental health and encompassed three dimensions: positive mindset, acquiring mental health information, and being aware of one's mental health. Positive thinking pertains to maintaining self-esteem, self-confidence, rationality, calmness, and a positive outlook in the face of adversity. Mental health information acquisition pertains to the ability to obtain relevant information about mental health. Mental health awareness refers to the extent to which individuals prioritize and value their mental well-being. The assessment consists of a total of eight questions, each carrying a score ranging from 1 to 4 points. A minimum score of 24 points is considered the desired target.

(3) Case questions primarily assess mental health skills, including the identification of psychological disorders with correct rates of identifying depression and social anxiety disorders. Psychological professional help-seeking attitudes are also evaluated, as well as the ability to overcome illness stigma. The identification of mental illness refers to the prompt detection and recognition of mental health issues in oneself or others. Psychological professional help-seeking attitudes reflect the tendency to seek assistance from mental health professionals when experiencing psychological problems. Overcoming distress involves conquering feelings of self-ill pubarche and public ill pubarche. Self-illness stigmatization refers to the internalized negative experiences associated with mental illness, which often result in attitudes and behaviors such as social avoidance and concealing one's condition. Public disease stigma refers to societal attitudes and biases towards mental illness, including rejection, discrimination, and contempt. Each case consists of four questions, and there are a total of two cases. The maximum score is 40 points, with a passing threshold set at a minimum of 28 points.

(4) Measurement standards for individual mental health literacy: the total score of judgment questions is greater than or equal to 80 points; the total score of self-assessment questions is greater than or equal to 24 points, and the total score of case questions is greater than or equal to 28 points. Level of mental health literacy (%) = (number of people who achieved the mental health literacy standard / number of people surveyed) × 100%.

Statistical analysis

The IBM SPSS Statistics 26.0 (IBM Corp, Armonk, New York) basic package was utilized for database curation and statistical analysis. For descriptive statistical estimation of constituent ratios and prevalence among populations with different characteristics, the complex samples package was employed. The distribution of various sociodemographic characteristics in the study population and the comparison of rates were analyzed using the Rao Scott correction for sampling designχ2 test. To compare the scores of positive mindsets, mental health information acquisition, mental health awareness, psychological disease recognition, overcoming illness stigma, and psychological professional help-seeking attitude between urban and rural residents, an independent sample t-test was conducted. Additionally, binary multivariate logistic regression was employed to investigate the factors associated with mental health literacy. Statistical significance was determined using two-sided testing with α = 0.05.

Demographic Data of Rural and Urban Adults

The planned sample size for this investigation was 53605, and one permutation was used for those lost to follow-up in the initial sample, with an average permutation rate of 14.89%, and the actual completed effective sample was 51774, with an effect response rate of 84.37%.31802 (61.4%) were urban and 19972 (38.6%) were rural. Table 1 preliminarily shows the urban-rural residents’ differences in demographic and health-related factors.

There was no apparent disparity in the sex ratio between urban and rural residents. However, it was observed that adult residents in urban areas tended to be younger, more educated, and more likely to be unmarried when compared to their rural counterparts. Additionally, the per capita income of households in rural areas was significantly lower than that of urban areas. Moreover, rural regions exhibited a higher prevalence of chronic diseases in comparison to urban areas. Furthermore, the study also disclosed that urban residents had a higher proportion of mental worker and spent more time using mobile phones. They also had a lower percentage of individuals who currently smoke or consume alcohol, and they generally followed healthier dietary and exercise habits. Conversely, urban areas had a higher occurrence of obesity and underweight individuals (Table 1).

Comparison of mental health knowledge among urban and rural residents

Nearly half of the subjects in the mental health knowledge entry responded correctly less than 50% for urban and rural residents. The knowledge rate of rural residents is higher than that of urban residents for item 16, "Hypertension, coronary heart disease and gastric ulcer are all psychosomatic diseases". For the remaining 19 items, the knowledge rate of urban residents was higher than that of rural residents(Table 2).

Comparison of achievement rates of mental health literacy between urban and rural residents

The rate of achievement of mental health literacy was 13.6% among urban residents, which was significantly higher compared to the rate of 8.6% among rural residents. The attainment of mental health skills was also higher among urban residents (17.3%) than rural residents (11.6%), while the rate of attainment of mental health knowledge levels was lower among urban residents than among rural residents (88.9% vs. 91.5%). These differences were also seen in the respective subscales. Urban residents performed better in areas such as mental health awareness, identification of psychological diseases, and overcoming illness stigma. Conversely, rural residents showed higher scores in positive mentality, mental health information acquisition, and seeking psychological professional help. Similarly, urban residents displayed higher rates of correct identification of depression and social anxiety disorders compared to their rural counterparts (Table 3,Fig. 1 and Fig. 2). Such results also exist between rural and urban residents at different ages and by gender, as described in the supplementary material (Supplement table1and Table 2).

Regression analysis of factors related to mental health literacy among urban and rural residents

The findings revealed that certain factors were associated with the attainment of mental health literacy in urban residents. Specifically, being female, having an education level of 12 years or higher, being Mental worker, being a retiree, having a higher monthly household income, maintaining a regular diet, and using electronic products for 2–6 hours per day were all protective factors for mental health literacy attainment. On the other hand, having chronic diseases, being a smoker, having a history of drinking, and being manual worker were identified as risk factors. In contrast, among rural dwellers, being married, being younger, having an education level of 12 years or higher, being mental worker and manual worker, using electronic products for 2–6 hours per day, maintaining a regular diet, and engaging in regular exercise were protective factors for achieving mental health literacy. Additionally, previous smoking was identified as a risk factor.

This report primarily presents the fundamental situation of mental health literacy among urban and rural residents of Guangdong Province in China, specifically in the year 2022. The results indicate that only 13.6% of the urban population in Guangdong Province achieved the required mental health literacy level, while just 8.6% of rural residents attained the targeted level. Unfortunately, these figures fall significantly short of the 20% target set for the 2022 resident health literacy level, as proposed by the Action Advancement Committee of Health China. Thus, it is evident that the overall mental health literacy level among Guangdong residents remains distressingly low. The reason behind this is that the mental health knowledge amongst both urban and rural residents is lacking. This is similar to previous studies in other Chinese provinces[23, 24]. The target rate for urban and rural residents' mental health knowledge is only 17.3% and 11.6% respectively. According to Table 2, it is evident that the correct rate for the knowledge of nine problems amongst urban residents is less than 50%. For instance, the correct rate for recognizing the importance of developing children's self-confidence is only about 10%, indicating that residents have limited knowledge about the mental health of children and adolescents. To address this issue, it is necessary to enhance the promotion of children's and adolescents' mental health knowledge at the social, school, and family levels. Moreover, the correct rate for identifying emotions that are not harmful or beneficial, such as anxiety, is also very low, less than 20% for both urban and rural residents. This suggests that people lack sufficient knowledge about the function of negative emotions. Additionally, residents show low rates of correct knowledge for seven other questions, which calls for the development of corresponding educational materials to improve knowledge in these areas. By strengthening promotional and educational efforts, it is possible to enhance the mental health knowledge of residents[25].

Both urban and rural residents displayed a higher compliance rate in the self-assessment part, which pertains to attitudes towards mental health, compared to the knowledge judgment (mental health knowledge) and case part (mental health skills). This difference may be attributed to the fact that the self-assessment primarily assesses one's state of mind and awareness of mental health when confronted with challenges, which is not closely linked to knowledge. The discrepancy in dimensional outcomes indicated that the majority of urban and rural residents possessed a positive mindset and a heightened awareness of mental health. However, their understanding of mental health knowledge was not comprehensive enough, and this awareness did not translate into tangible actions. Consequently, the reciprocal relationship between mental health knowledge and skills was unable to foster positive reinforcement. The lack of mental health knowledge leads to a low level of psychological literacy, which has also been seen in some previous studies[26]. This suggests that merely having a positive mindset and awareness of mental health is insufficient. Therefore, all levels of government and health education must expand the range of mental health education, enhance the content of mental health education, and guide the general public towards acquiring comprehensive knowledge and skills in mental health. By doing so, the overall level of mental health literacy can be improved.

This study revealed significant disparities in mental health literacy between urban and rural populations. Urban residents demonstrated higher levels of mental health knowledge, as well as greater accuracy in identifying depression and social anxiety disorders. In terms of overcoming illness stigma and mental health awareness, urban residents excelled, obtaining higher recognition scores for mental illness. However, rural residents outperformed urban residents in positive mentality, mental health information acquisition, and seeking psychological professional help. These findings were consistent across different age groups and genders. Similar results can be seen in previous studies in China (Hong et al.; Song et al.2022). Several factors may contribute to these outcomes. Firstly, mental health promotion efforts in rural areas are inadequate, resulting in less attention to mental health and limited access to knowledge resources for residents. Secondly, significant variations exist between urban and rural areas in terms of economic conditions and cultural environment. Urban residents enjoy better economic prospects and have access to a wide range of educational opportunities, including mental health education. Thirdly, urban residents face higher living costs and work-related stress, which may render them more susceptible to mental inactivity. These findings corroborate previous studies that suggest mental health literacy levels are higher among urban residents, signaling the need for increased mental health education targeting rural residents to enhance their psychological literacy. Additionally, greater emphasis should be placed on cultivating a positive mindset among urban residents to effectively navigate life challenges.

The results of logistic regression analysis revealed that several factors were protective mental health literacy levels in urban residents. These included being female, having a higher level of education, possessing a higher economic income, using electronic products for 2–6 hours per day, being mentally active or retired, maintaining a regular diet. However, being engaged in physical work having chronic diseases, a history of smoking, or previous alcohol consumption. was identified as a risk factor. In contrast, the protective factors of mental health literacy in rural residents were being married, having a higher level of education, being mentally and physically active workers, using electronic products for 2–6 hours per day, regularly exercising, and maintaining a regular diet. The only identified risk factor among rural residents was previous smoking. Consistent with previous research, this study found that women had higher levels of mental health literacy compared to men[2, 27, 28]. This may be due to the fact that women are more intuitive about emotional understanding, or that women tend to use psychological and emotional labels more than men[29, 30]. The positive correlation observed between educational attainment, monthly family income, and mental health literacy in urban residents aligns with findings from prior studies[31, 32]. It suggests that individuals with lower education and income levels may have limited access to mental health resources and pay less attention to mental health knowledge. In contrast, individuals with higher education and income levels tend to lead healthier lifestyles, experience lower disease burden, and have more available mental health resources. The higher levels of mental health literacy observed among mental force workers and retirees, compared to those without these professions, may be due to their lower education and income levels, which limit their access to various resources. Also, employment is an important mental health intervention[33].

Individuals without chronic diseases exhibited higher levels of mental health literacy than those with chronic diseases. Previous studies have also shown lower levels of mental health literacy in patients with chronic diseases[34]. This may be attributed to the emphasis on physical health over mental health in medical treatment, resulting in limited proactive access to mental health-related resources. The findings suggesting that individuals who use electronic products for 2–6 hours have better mental health literacy compared to those who use electronic products for less than or equal to 2 hours may be because mental health literacy knowledge is primarily web-based. Furthermore, lifestyle habits such as smoking, drinking, following a regular diet, and engaging in regular exercise were associated with mental health literacy. This may be because adverse habits like smoking and drinking are linked to negative emotional events[34, 35], ultimately impacting mental health. Individuals who follow a regular diet and engage in regular exercise tend to lead more active lifestyles and prioritize their mental well-being[36], leading to higher levels of mental health literacy. In conclusion, promoting good lifestyle habits can positively impact mental health literacy and should be a focal point in future interventions.

The study also found that younger age and being married were protective factors for mental health literacy among rural residents. This is similar to previous studies[28, 37]. This could be attributed to younger individuals in rural areas having a higher level of education and the fact that China didn't implement 9-year compulsory education until 1986. As a result, older individuals may have lower levels of education and less access to mental health education knowledge. Additionally, the higher levels of mental health literacy observed among married individuals align with findings from previous study[38], which also highlighted higher marriage rates in rural areas compared to urban areas. These results illustrate the differing influence factors on mental health literacy between urban and rural populations. Therefore, future interventions should target these factors individually to achieve better outcomes. In conclusion, the study revealed a low level of mental health literacy among urban and rural residents of Guangdong Province, with a significant disparity between the two areas. These findings highlight the need for continuing efforts to increase the dissemination of mental health knowledge in rural communities and improve overall levels of mental health literacy.

The findings need to consider some limitations. Firstly, it is important to note that this study is a cross-sectional study and therefore cannot provide insights into trends or establish causality regarding changes in mental health literacy among residents. Secondly, the survey failed to adequately assess the effects of recent life events on respondents' psychology. Despite these limitations, the survey had several notable strengths. Firstly, the effective questionnaire used in this survey met the minimum requirements and strictly adhered to the principle of stratified sampling. Additionally, the sample selected was highly representative, thus enabling the findings to be generalizable to the overall mental health literacy of Guangdong Province residents. Secondly, the sample size of 51,774 participants was sufficiently large for conducting this investigation. Thirdly, this study investigated the impact of common demographic factors on mental health literacy, providing a more comprehensive understanding of how these factors influence knowledge in this domain. Lastly, the use of on-site investigation methods ensured the reliability of the data collected.

The findings indicate a concerning lack of mental health literacy among both urban and rural residents of Guangdong Province. Furthermore, there is a significant disparity between mental health literacy levels in urban and rural areas. It is imperative to initiate follow-up actions in order to promote the dissemination of mental health information to rural residents, thereby improving their overall mental health literacy.
