Belief in a just world and meaning in life among Chinese adolescents: The mediating role of basic psychological need satisfaction.

Previous literature has shown that adults with higher belief in a just world (BJW) experience greater meaning in life than those with less pronounced BJW. However, the role of BJW in adolescent meaning in life and the associated psychological mechanisms remain unclear. Thus, two studies were conducted to explore the roles of personal belief in a just world (PBJW) and general belief in a just world (GBJW) in meaning in life as well as the explanatory role of basic psychological need satisfaction among Chinese adolescents. Study 1 offered cross-sectional evidence that individuals higher in PBJW and GBJW displayed greater meaning in life, and basic psychological need satisfaction accounted for these associations. Study 2 provided longitudinal evidence that individuals higher in PBJW and GBJW at Time 1 exhibited greater meaning in life six months later (Time 2), wherein basic psychological need satisfaction at Time 1 served as a mediator. These findings contribute to understanding the adaptive benefits of PBJW and GBJW in meaning in life during adolescence and point to a crucial channel connecting BJW and meaning in life.

Birth cohort changes in anxiety levels among primary school students in China during 1995-2019: A cross-temporal meta-analysis.

To investigate birth cohort changes in anxiety levels among primary school students in China, we conducted a cross-temporal meta-analysis of 126 studies (N = 109,957) reporting the anxiety levels among primary school students in China during 1995-2019 using the Mental Health Diagnostic Test (MHT); higher MHT scores indicated higher anxiety. The results showed that: (1) The MHT scores for five types of mental health problems (social anxiety, lonely tendency, physical symptoms, terror tendency, and impulsive tendency) and the total MHT score were significantly negatively correlated with the data-collection year, indicating that the anxiety levels among primary school students in China decreased over time. (2) The MHT score for learning anxiety was significantly positively correlated with the data-collection year, indicating that the learning anxiety levels of primary school students in China increased over time. (3) The overall MHT score did not show significant gender differences, but gender-wise varying trends were observed in the types considered.

Changes of medical staffs' subjective well-being in China (2004-2020): A cross-temporal meta-analysis.

Subjective well-being is a crucial index measuring the mental health of medical staffs, and it is necessary to examine the changes in subjective well-being (SWB) level of Chinese medical staffs with time. A cross-temporal meta-analysis was performed using papers that measured the SWB level of Chinese medical staffs between 2004 and 2020. Moreover, a time-lag analysis was conducted to define whether the macro-social indicators can explain the changes in SWB. A total of 47 papers were included in the final sample. The results revealed that score of SWB was significantly negatively correlated with the year. Score of SWB was significantly associated with six social indicators of economic condition (the residents' consumption level, housing prices, and old-age dependency ratio), social connectedness (the divorce rate and the urbanization level), and overall threat (the crime rate), which indicated that social change may account for the decline of Chinese medical staffs' SWB level. Our study revealed a decreasing trend of Chinese medical staffs' SWB level over time, which was associated with macro-social changes in diverse areas. In addition, combined with the corresponding macro-social indicators, a three-dimensional theoretical framework is proposed to explain the SWB for medical staffs as a group.

Changes in mental health levels among Chinese physical education college students from 1995 to 2019.

To explore the changes in the mental health levels of Chinese physical education college students, the present study conducted a cross-temporal meta-analysis of 43 papers that adopted the Symptom Checklist 90 (SCL-90) from 1995 to 2019. The results showed that the average scores of the seven SCL-90 factors were negatively correlated with the year of data collection. The socioeconomic indicators (GDP, per capita GDP and household consumption level) were significantly negatively correlated with the eight dimension scores of the SCL-90 (except for phobic anxiety). The mean effect sizes of the sex differences in the seven dimension scores (except depression and phobic anxiety) were lower than the small effect size. In conclusion, Chinese physical education college students' mental health levels have increased in the past 25 years. This phenomenon may be related to Chinese socioeconomic growth, the implementation of national sports policies, and the provision of mental health education for college students. In addition, although the increasing trend in the mental health level of female students was more obvious, there were no significant sex differences.

Psychological security in Chinese college students during 2006-2019: The influence of social change on the declining trend.

BACKGROUND: As a key indicator to measure the mental health status, psychological security level of Chinese college students and its changes over time are of great value to examine. METHODS: A cross-temporal meta-analysis was performed using papers that measured the psychological security level of Chinese college students using the Security Questionnaire between 2006 and 2019. In addition, a time lag analysis was conducted to define whether the selected macro social indicators can explain the changes in the psychological security level. RESULTS: A total of 58 papers involving 28,352 Chinese college students were included in the final sample. The results revealed that scores of psychological security and its two factors were significantly negatively correlated with the year. Scores of psychological security and its two factors were significantly associated with five social indicators of economic condition (residents' consumption level), social connectedness (divorce rate, urbanization level) and overall threat (college enrollment rate, crime rate), suggesting that social change may account for the decline in psychological security level of Chinese college students. LIMITATIONS: The underlying mechanism is only discussed at a theoretical level. Thus, future studies can collect the relating empirical evidence to test the proposed theoretical model. CONCLUSIONS: Our study revealed a decreasing trend of Chinese college students' psychological security level across time, which was associated with macro-social changes in diverse areas. In addition, combined with the corresponding macro-social indicators, a three-dimensional theoretical framework is proposed to explain the psychological security for college students as a group.

Changes in Work-Family Conflict of Chinese Employees: A Cross-Temporal Meta-Analysis, 2005-2016.

With the rapid growth of China's economy, work-family conflict (WFC) level of Chinese employees might have changed over time. The present research performed a cross-temporal meta-analysis of 71 papers using the Work-Family Conflict Scale (WFCS) from three Chinese academic databases and three databases in English to investigate changes in Chinese employees' WFC (N = 23,635) during 2005-2016. Results showed that the WFC level of employees increased significantly by 0.77 standard deviations over the past 12 years. The increasing trend over time occurred among both male and female employees, which is slightly more salient among male employees. However, there was no significant gender difference in WFC scores. This study found that the increase in WFC scores among Chinese employees was associated with scores of six social indicators that might cause stress in workplace (the number of employees and number of college graduates) and stress in family (divorce rate, residents' consumption level, elderly dependency ratio, and family size) of 5 years before and the year of data collection, which indicates that social changes played an important role in changes of WFC. The explanations and implications of these changes are discussed.

Changes in Chinese nurses' mental health during 1998-2016: A cross-temporal meta-analysis.

In China, nursing is a profession with considerable stress, which may cause both physiological and psychological problems. The present study conducted a cross-temporal meta-analysis of 244 papers using the Symptom Checklist 90 (SCL-90) to investigate the changes in the mental health level of Chinese nurses (N = 71,286) from 1998 to 2016. Results showed that (a) relationships between scores of all nine types of mental problems in the SCL-90 and year were significantly positive, indicating that the mental health level of nurses decreased steadily in the past 19 years; (b) relationships between three social indicators (patient-to-nurse ratio, unemployment rate, and divorce rate) and scores of all nine types of mental problems in the SCL-90 were significantly positive, suggesting that the increase in these social indicators may be responsible for the decrease in Chinese nurses' mental health level.
