Background: Sport Mental Health Continuum - Short Form (Sport MHC-SF) is an adaptation of the Mental Health Continuum-Short Form for athletes. Although validated in Western contexts, its applicability to the Chinese population remains unexplored. This study aims to validate the Chinese adaptation of the Sport MHC-SF in Chinese university athletes, evaluate its reliability and validity, and confirm its factorial structure.

Methods: A total of 1,025 Chinese university athletes (65% male, mean age 20 ± 1.54 years) were included in this study. Confirmatory factor analysis (CFA) and multi-group CFA (MGCFA) were conducted using Mplus 8.0 to evaluate the factorial structure and assess measurement invariance across sports levels.

Results: Both the three-factor and second-order models demonstrated a good fit for the Chinese adaptation of the Sport MHC-SF. Chi-square values were 262.704 (74) and 262.705 (74), respectively, with a comparative fit index (CFI) of 0.968, a Tucker-Lewis index (TLI) of 0.961, a standardized root mean square residual (SRMR) of 0.027, and a root mean square error of approximation (RMSEA) of 0.050 (90% CI: 0.043-0.056). Measurement invariance across ranked and non-ranked athletes was confirmed, with minimal changes in fit indices (ΔCFI ≤ 0.01, ΔTLI ≤ 0.01, ΔRMSEA ≤ 0.015) from configural to strict invariance.

Conclusion: The Chinese adaptation of the Sport MHC-SF scale has strong construct validity, reliability, and measurement invariance, making it a reliable tool for future research on the well-being of Chinese athletes. This study fills a critical gap in cross-cultural validation, offering a foundation for future research and practical applications in sports psychology among Chinese athletes.

Background: Nurses frequently encounter death due to their professional roles, impacting their perceptions of mortality. Previous research has largely focused on the negative aspect of death awareness, known as death anxiety, while the other aspect, death reflection, has been less explored. This study aims to investigate the profiles of death awareness among Chinese nurses and identify factors influencing these profiles, such as socio-demographic characteristics, work-related characteristics, death education, and resilience.

Method: A cross-sectional study was conducted using a convenience sample of 2882 nurses across China. Data were collected through an online survey from September to November 2023. Latent Profile Analysis was utilized to identify distinct profiles of death anxiety and death reflection among nurses. Multinomial logistic regression was used to analyze the predictive factors for different death awareness profiles.

Results: Three distinct profiles were identified: Calm Reflectors (low death anxiety, high death reflection), The Anxious (high death anxiety, low death reflection), and Anxious Reflectors (high levels of both death anxiety and death reflection). Factors such as resilience, years of service, parental status, education level, and read death education-related information significantly predicted the classification into these profiles. Specifically, higher resilience and engagement in death education were associated with the Calm Reflectors profile.

Conclusions: Our study suggests that nurses' death awareness can be categorized into three distinct profiles: Calm Reflectors, The Anxious, and Anxious Reflectors. Key predictors of these profiles include resilience, educational level, years of service, parental status, and read death education-related information. The findings suggest that enhancing resilience and targeted educational interventions are crucial for supporting nurses in managing death-related emotional and cognitive responses effectively.

Background: Wars profoundly impact mental health with growing long lasting consequences. This study assessed the prevalence of post-traumatic stress disorder (PTSD) and well-being among Sudanese affected by the ongoing conflict, with a specific focus on healthcare workers (HCWs).

Methods: A cross-sectional study was conducted between April 1 and June 30, 2024, using the validated Arabic versions of PTSD Checklist for the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) (PCL-5) and the World Health Organization (WHO)-5 Well-Being Index.

Results: A total of 1022 participants were included, and 44% were recruitted through online questionnaire and face-to-face interviews. Their mean age was 31.4 ± 12.5 years, 63.4% were females, 16.3% were HCWs and 83.3% were displaced due to conflict. The mean score of PTSD was 35 ± 21.3 with 56.9% having PTSD. The mean well-being score was 55.0 ± 23.9 with 40% reporting poor well-being. Among HCWs, 60.5% suffered from PTSD and 27.5% experienced poor well-being. A significant negative correlation was observed between PTSD and well-being scores (r=-0.273, p < 0.001). Predictors of PTSD were being male [β = -10.91, 95% confidence interval (CI) (-13.44, -8.38); p < 0.001], urban area resident [β = -10.38, 95%CI (-18.78, -1.98); p = 0.016], non-medical profession [β = 5.07, 95%CI (1.46, 8.67); p = 0.006], living with 2 to 10 households [β = 6.69, 95%CI (0.46, 12.91); p = 0.035], living with more than 20 households [β = 13.20, 95%CI (4.17, 22.23); p = 0.004], insufficient income [β = 4.32, 95% CI (1.84,6.81); p = 0.001], living in conflict zones [β = 13.38 95%CI (8.83,17.92); p < 0.001], refugee resettlement [β = 13.18, 95%CI (9.98,16.38); p < 0.001], and well-being score [β = -0.20, 95%CI (-0.25, -0.15); p < 0.001]. Predictors of well-being scores were living with more than 20 households [β = -17.44, 95%CI (-28.83, -6.04); p = 0.003], being a HCW [β =-6.22, 95%CI (-11.87, -0.57); p = 0.031], being a student [β = -7.55, 95%CI (-12.94, -2.16), p = 0.006, insufficient income [β = -5.04, 95%CI (-8.17, -1.90); p = 0.002], and living in conflict zones [β = -8.22, 95%CI (-13.96, -2.48); p = 0.005].

Conclusions: The study highlights an alarmingly high prevalence of PTSD among Sudanese including HCWs, with significant mental health consequences. These findings emphasize the urgent need for mental health interventions and humanitarian support to mitigate the psychological challenges faced by the conflict affected population.

Objective: This Research explores the intermediary function of academic stress and sleep quality in the connection between physical exercise and subjective well-being among high school students.

Methods: This Research conducted an online survey through random sampling with a sample of 540 (males = 310, females = 217; grade 10 = 159, grade 11 = 190, grade 12 = 178) high school students to explore the intermediary function of academic stress and sleep quality between physical exercise and subjective well-being. The participants were surveyed using PSQI, the Subjective Well-Being Scale, the ESSA, and PSQI. SPSS Statistics 26 was used to conduct reliability and validity tests, descriptive statistics, and correlation analysis. Mediation analysis was conducted utilizing Model 6 from the PROCESS 4.0 plugin.

Results: (1) Physical exercise shows a significant positive correlation with subjective well-being, and the direct impact of physical exercise on subjective well-being is also significant. (2) Physical exercise adversely affects academic stress and positively influences sleep quality. Academic stress negatively impacts sleep quality and subjective well-being, while sleep quality positively influences subjective well-being. (3) Academic stress and sleep quality serve as significant mediators between physical exercise and subjective well-being. The mediation effect encompasses two indirect paths: In one aspect, physical exercise has an indirect impact on subjective well-being through its influence on academic stress; in another aspect, physical exercise indirectly affects subjective well-being via the chain mediation effects of academic stress and sleep quality.

Conclusion: Physical exercise can directly influence the subjective well-being of high school students. Additionally, physical exercise can indirectly impact their subjective well-being through academic stress, and it can also indirectly influence their subjective well-being through the chain mediation effect of academic stress and sleep quality. Based on these findings, it is recommended that schools provide more opportunities for physical exercise, integrated with psychological counseling and sleep management, to help students effectively alleviate academic stress, thereby enhancing their overall well-being.

Background: The increasing demand for psychotherapy and limited access to specialists underscore the potential of artificial intelligence (AI) in mental health care. This study evaluates the effectiveness of the AI-powered Friend chatbot in providing psychological support during crisis situations, compared to traditional psychotherapy.

Methods: A randomized controlled trial was conducted with 104 women diagnosed with anxiety disorders in active war zones. Participants were randomly assigned to two groups: the experimental group used the Friend chatbot for daily support, while the control group received 60-minute psychotherapy sessions three times a week. Anxiety levels were assessed using the Hamilton Anxiety Rating Scale and Beck Anxiety Inventory. T-tests were used to analyze the results.

Results: Both groups showed significant reductions in anxiety levels. The control group receiving traditional therapy had a 45% reduction on the Hamilton scale and a 50% reduction on the Beck scale, compared to 30% and 35% reductions in the chatbot group. While the chatbot provided accessible, immediate support, traditional therapy proved more effective due to the emotional depth and adaptability provided by human therapists. The chatbot was particularly beneficial in crisis settings where access to therapists was limited, proving its value in scalability and availability. However, its emotional engagement was notably lower compared to in-person therapy.

Conclusions: The Friend chatbot offers a scalable, cost-effective solution for psychological support, particularly in crisis situations where traditional therapy may not be accessible. Although traditional therapy remains more effective in reducing anxiety, a hybrid model combining AI support with human interaction could optimize mental health care, especially in underserved areas or during emergencies. Further research is needed to improve AI's emotional responsiveness and adaptability.

In second language acquisition research, the psychological factors associated with language learning have been a prominent focus. The affective turn in and introduction of positive psychology in this field have further boosted research on the roles of positive learner psychological factors (e.g. motivation) in performance (e.g. engagement). However, the theoretical lens for investigating these variables requires further clarification, and the roles of some variables (e.g. boredom) in language learning have been under-researched. Guided by this background, this study aims to explore the complex relationships between learners' basic psychological needs, self-determined motivation, boredom and behavioural engagement among 687 Chinese senior high school EFL learners from the perspective of self-determination theory (SDT). Quantitative data collection and analysis revealed that students' basic psychological needs directly predicted behavioural engagement. Basic psychological needs also indirectly predicted behavioural engagement through the simple mediation of boredom and the chain mediation of self-determined motivation and boredom. However, the simple mediation of self-determined motivation in the relationship between basic psychological needs and behavioural engagement was non-significant. The findings enrich the application of SDT in the language learning engagement research, providing valuable implications for teachers and educators.

Background: Childhood subjective socioeconomic status (operational definition of harshness) and unpredictability significantly influence life history strategies and subsequent psychological and behavioral patterns. Existing research on Chinese populations has been limited by inconsistent metrics and inadequate measurement items. This study aimed to adapt and validate the Chinese versions of the Childhood Perceived Poverty and Wealth Questionnaire (C-CPPWQ) and the Childhood Perceived Unpredictability Questionnaire (C-CPUQ), addressing cultural differences and expanding measurement subjects.

Methods: We conducted Exploratory Factor Analysis (EFA) with 493 students and Confirmatory Factor Analysis (CFA) with 1217 students to validate the factor structures. Concurrent validity was assessed using correlations with life history strategies (Mini-K) and childhood trauma (CTQ-SF) and reliability were also evaluated.

Results: The C-CPPWQ's two-factor model (perceived wealth and perceived poverty) demonstrated good fit (CFI = 0.95; TLI = 0.94; SRMR = 0.05; RMSEA = 0.08) and strong internal consistency (alpha = 0.90), with significant correlations with Mini-K (r = -0.28, p < 0.001) and childhood trauma (r = 0.29, p < 0.001). The C-CPUQ's three-factor model (Unpredictability of Parenting, Unpredictability of External Environment, and Unpredictability of Daily Happening) also showed a good fit (CFI = 0.96; TLI = 0.95; SRMR = 0.04; RMSEA = 0.07) and high reliability (alpha = 0.95), with significant correlations with Mini-K (r = -0.39, p < 0.001) and childhood trauma (r = 0.72, p < 0.001).

Conclusions: The newly adapted 14-item C-CPPWQ and 16-item C-CPUQ for Chinese contexts exhibit satisfactory psychometric properties, making them valuable tools for researching and evaluating childhood adversity.

Internet usage has become an inevitable part of daily life. Adolescents who are developmentally vulnerable due to family dynamics or who suffer psychological distress are at greater risk of problematic Internet use. This study aims to reveal the intricate psychological pathways linking family social support to problematic Internet use among adolescents and the mediating roles of hostility and depression. The study uses serial mediation analyses and Hayes PROCESS macro to examine a large sample of 2,047 adolescents (1,182 females and 865 males). Results revealed a significant negative association between family social support and problematic Internet use. Both hostility and depression were found to be critical mediators, functioning independently and sequentially in the relationship between family social support and problematic Internet use. The findings highlight the protective role of family social support against problematic Internet use among adolescents by reducing hostility and depressive symptoms. This investigation contributes to the extant literature by elucidating the psychological mechanisms underlying problematic Internet use. It suggests that interventions targeting family support systems, feelings of hostility, and depression may effectively mitigate problematic Internet use among adolescent populations.

Gender differences in interoceptive awareness-awareness of internal bodily signals such as heartbeat perception-have been suggested, with some findings indicating behaviourally reduced but subjectively enhanced awareness in women, though these findings are still contentious. This study aimed to comprehensively examine gender differences in three aspects of interoceptive awareness: behavioural accuracy, subjective confidence, and relationship between them (i.e., metacognition). We used a modified heartbeat counting task that prohibited estimation strategies and increased the number of trials up to 20. Using data from 74 healthy young adults (39 women and 35 men), we evaluated gender differences and practice effects for each measure via Bayesian linear mixed models, controlling for individual heart rate and trial duration on a trial-by-trial basis. Contrary to previous research, the results revealed no reduced interoceptive accuracy in women; instead, higher interoceptive accuracy score was associated with shorter trial durations and lower heart rates regardless of gender. Moreover, women exhibited underconfidence about their performance, and therefore lower metacognition scores, compared to men. Trial repetitions moderated women's lowered metacognition but did not affect accuracy or confidence. These findings highlight potential physiological and psychological confounding factors in the heartbeat counting task, such as heart rate and reporting style, and emphasise several cautions for studying gender differences in interoceptive awareness.
