Background: Teachers in high-stress roles face increasing psychological distress such as anxiety and depression, underscoring the need for validated assessment instruments. Given the current absence of a comprehensive, designated, and time-efficient scale capable of evaluating depression, anxiety, and stress among the teacher population, the Depression, Anxiety, and Stress Scale-21 (DASS-21) presents itself as a promising alternative. Despite the widespread application of the DASS-21 for assessing psychological distress across various populations, its validity among teachers, along with questions about its factor structure and its potential property of time equivalence, remain unverified. This study endeavors to address these considerations by investigating the psychometric properties of the DASS-21 specifically within the population of Chinese primary and middle school teachers.Methods: Cross-sectional (n = 9,030) and longitudinal surveys (n = 1,642) were conducted using a non-probability sampling method. In addition to the DASS-21, the Chinese version of Chinese Teachers’ Job Burnout Questionnaire (CTJBO) was utilized to evaluate the criterion validity of this scale. Three different approaches, namely confirmatory factor analysis, Rasch analysis, and network analysis, were employed to evaluate internal reliability, construct validity, as well as time invariance of the DASS-21.Results: The DASS-21 demonstrated a high degree of internal consistency (Cronbach’s α > 0.85) as well as excellent convergent validity, despite poor discriminant validity as determined by average variance extracted. Confirmatory factor analysis and network analysis further supported convergent validity. The three-factor structure outperformed one- and two-factor alternatives, establishing time invariance. Rasch analysis at the item level identified six inappropriate items within the anxiety and stress subscales, which were subsequently removed. Network analysis presented a better revised network. Regression analysis with emotional exhaustion as the criterion provided logical and accurate results.Conclusion: The DASS-21 was found to be a reliable and valid tool for measuring the mental health of teachers over time. To assess the instrument’s psychometric properties, a combination of confirmatory factor analysis, Rasch analysis, and network analysis was utilized, which proved effective and is recommended for evaluating contentious instruments. Based on the results of the study, researchers and healthcare professionals are recommended to use the DASS-21 for assessing teachers’ psychological distress. However, certain items identified in the study may need to be removed to enhance the instrument’s appropriateness for this specific population.

Background: In recognizing the need for a reliable and valid instrument to assess psychological distress among children and adolescents, the present study translated the newly developed Depression Anxiety Stress Scale for Youth (DASS-Y) into Chinese, while also comparing its psychometric properties with those of the well-established DASS-21 within a primary and middle school demographic. Methods: Utilizing a combination of convenience sampling and purposive sampling, a cohort comprising 1,507 primary and 1,131 middle school students was recruited. Rasch analysis, confirmatory factor analysis (CFA), and structural equation modeling (SEM) were used in the data analysis. Results: Significant differences were observed between the DASS-Y and the DASS-21, notably within the anxiety subscale. The proportions of individuals with clinical mood disorders identified by the two scales demonstrated a significant disparity. Both scales, following an adjustment of responses, exhibited satisfactory internal consistency and convergent validity, with the acceptance of a three-factor structure. Furthermore, the DASS-Y showed superior discriminant validity relative to the DASS-21, providing more compelling evidence regarding concurrent validity. Conclusion: Overall, the Chinese version of the DASS-Y demonstrated superior robustness to the DASS-21 in terms of psychometric properties. The findings provide initial evidence for the psychometric properties of the DASS-Y from another culture.

During transitional periods, college freshmen may experience mental health issues. The Depression, Anxiety, and Stress Scale—21-item version (DASS-21) is commonly used for mental health assessment in China. However, evidence is lacking regarding its applicability with freshmen as a demographic. Debates also exist regarding its factor structure. This study aimed to evaluate the DASS-21′s psychometric properties with Chinese college freshmen and investigate its association with three kinds of problematic Internet use. A convenience sampling method was used to recruit two samples of freshmen—one of 364 (female 248; mean age 18.17 years) and the other of 956 (female 499; mean age 18.38 years) participants. McDonald’s ω and confirmatory factor analysis were conducted to evaluate both the scale’s internal reliability and construct validity. The results indicated acceptable reliability, with a one-factor structure inferior to a three-factor structure in terms of model fit. Furthermore, it was demonstrated that problematic Internet use was significantly and positively associated with depression, anxiety, and stress among Chinese college freshmen. Based on the prerequisite of measurement equivalence across two samples, the study also found that freshmen’s problematic Internet use and psychological distress were likely to be affected by the strict measures put in place during the COVID-19 pandemic.

Teachers in demanding work environments are prone to anxiety, depression, and stress. Validated measures across different cultural contexts are required. The present study evaluated the psychometric properties of the 21-item Depression, Anxiety and Stress Scale (DASS-21) and DASS-12 and DASS-8 among Spanish and Chinese primary school teachers. A total of 3930 primary school teachers were recruited, comprising samples from Spain (n = 1350) and China (n = 2580). Scale structure was analyzed using confirmatory factor analysis (CFA) and exploratory structural equation modeling (ESEM). Model comparisons were conducted to identify the best-fitting factor structure. Convergent and discriminant validity were examined, and concurrent validity was assessed using emotional exhaustion as a criterion variable. Optimal diagnostic thresholds were established through latent profile analysis (LPA) and receiver operating characteristic (ROC) analysis. Among the tested factor structures (unidimensional, oblique three-factor, ESEM, bifactor, and bifactor ESEM models), the ESEM model demonstrated superior fit indices, supporting acceptable factorial validity among both Spanish and Chinese samples. The DASS versions in the ESEM structure exhibited strong convergent, discriminant, and concurrent validity in the Spanish sample, while showing relatively weaker validity indices among the Chinese sample. Notably, the empirically derived cutoff scores for DASS-21 sub-dimensions among teachers were substantially higher than the originally recommended thresholds. The three DASS versions effectively assessed three types of psychological distress among Spanish teachers, while among the Chinese teachers, the DASS instruments appeared useful for assessing distress, though caution is recommended when using individual subscale scores.

Introduction: In light of the significant impact that teachers have on education quality and student growth, their mental health warrants special attention. With the increasing popularity of Information and Communication Technology (ICT) and the rise of online teaching during the pandemic, teachers have become a group prone to developing problematic smartphone use (PSU). Psychological need thwarting (PNT) has been shown to be closely related to PSU, psychological distress, and perceived administrative support. However, most previous studies have adopted a variable-centered approach, which may overlook the possibility that the three basic needs are not closely associated and could form distinct profiles. Therefore, this study aims to apply latent profile analysis to identify different PNT profiles and their associations with PSU, psychological distress, and perceived administrative support.Methods: A longitudinal survey was conducted using convenience and purposive sampling methods. The survey involved 1,642 primary and middle school teachers working in China over a two-month interval, with the first assessment in November 2021 (Time 1) and the second in January 2022 (Time 2).Results: The results indicate that a three-profile model, intricately based on the PNT data gathered at Time 1, is most optimal: Class 1 is labeled as ‘High autonomy-High competence and Moderate relatedness thwarting’, Class 2 as ‘High autonomy-High competence and High relatedness thwarting’, and Class 3 as ‘Low psychological needs thwarting’. Distinct associations were observed among the three profiles concerning PSU, psychological distress, and perceived administrative support. Specifically, in terms of PSU, the score of Class 2 was higher than Class 1, with that of Class 3 being the lowest at Time 1, while at Time 2 no significant difference was found between any two of these three groups; in terms of distress, the scores of the three profiles were arranged from high to low as Class 2, 1, and 3 at both time points; and in terms of perceived administrative support, the order was just the opposite, with 3, 1, and 2 from high to low at both Time 1 and Time 2.Conclusion: Notably, the consistent ranking of the three classes in terms of psychological distress and administrative support suggests a lasting influence of PNT. Future studies should explore this enduring impact further by employing additional longitudinal data sets and examining potential mediators or moderators beyond the current study’s scope.

Background Teachers' professional identity plays a critical role in shaping educational environments, particularly through its influence on teacher-student relationships and students' psychological resilience. Although the connection between professional identity and these factors is established, the indirect effect of professional identity on student resilience—mediated by teacher-student relationships and moderated by teachers' life satisfaction—has not been fully explored. This study investigates the impact of novice teachers' professional identity on seventh-grade students' psychological resilience, focusing on the mediating role of teacher-student relationships and the moderating effect of teachers' life satisfaction. Methods Data were collected from 69 novice teachers and 2,147 students across 10 middle schools in China. The study employed Hierarchical Linear Modeling (HLM) to analyze the direct and indirect effects of teachers' professional identity on students' psychological resilience, accounting for the nested data structure. Results The analysis revealed that a strong professional identity among novice teachers significantly enhances students' psychological resilience, primarily through the improvement of teacher-student relationships. However, the expected moderating effect of teachers' life satisfaction was not supported, possibly due to the uniformly high levels of life satisfaction among the participants. Conclusion These results underscore the importance of fostering a strong professional identity in novice teachers to cultivate positive teacher-student relationships, which are crucial for enhancing students' psychological resilience. The study offers valuable insights for educational policies and interventions aimed at supporting teacher development and improving student outcomes during the critical transition to middle school.
