Borderline personality disorder (BPD) is common among young adults. Related studies showed a wide range of prevalence among university students. Few studies regarding BPD symptoms and their correlations with different variables have been reported in the Chinese population. A cross-sectional, online survey was conducted on a sample of university students in China between November 2021 and January 2022. Sociodemographic questionnaires, the Screening Instrument for Borderline Personality Disorder (SI-Bord), the 18-item Experience in Close Relationships-Revised (ECR-R-18), the Meaning In Life Questionnaire (MLQ), the 10-item Perceived Stress Scale (PSS-10), the Patient Health Questionnaire (PHQ-9), the Rosenberg Self-Esteem Scale (RSES) and the Resilience Inventory (RI-9) were completed. Data were analyzed using Pearson’s correlation methods. Among 767 participants, mean age was 20.33 ± 1.495 years, and the majority were males (53.5%). According to the SI-Bord’s cut-off score >7, BPD symptoms were found in 17.5% of participants. Attachment anxiety, avoidance, depression, perceived stress, lack of meaning in life, resilience and self-esteem were significantly correlated with BPD symptoms with r’s of 0.473, 0.180, 0.451, 0.481, −0.148, −0.238 and −0.388, respectively (all p’s < 0.01). The prevalence of BPD symptoms is high among Chinese university students and significantly associated with mental health outcomes, suggesting that an early detection of BPD symptoms is necessary for this population.

Background: Borderline personality disorder (BPD), a significant personality trait frequently observed in young adults, is associated with challenges in mental health and academic performance. Screening for BPD symptoms is essential. The Screening Instrument for Borderline Personality Disorder (SI-Bord) is widely used to assess general BPD symptoms. However, despite being translated and culturally adapted, the psychometric properties of the Chinese version of the SI-Bord have not been thoroughly investigated in a Chinese population. Objectives: The aim of the study was to evaluate the psychometric properties of the Chinese version of the Screening Instrument for Borderline Personality Disorder (SI-Bord) among university students using confirmatory factor analysis (CFA). Methods: Participants completed the SI-Bord along with the Perceived Stress Scale (PSS), the Meaning in Life Questionnaire (MLQ), the Experiences in Close Relationships–Revised (ECR-R), and the Rosenberg Self-Esteem Scale (RSES). Results: A total of 715 Chinese university students (mean age = 20.33 years; age range = 18–25), including 385 males (54.2%) and 325 females (45.5%), participated in this study. The unidimensional model demonstrated adequate fit indices. The SI-Bord showed significant correlations with the PSS and ECR-R (attachment anxiety), alongside smaller correlations with the MLQ, supporting its convergent and discriminant validity. The Chinese version of the SI-Bord exhibited good reliability. Invariance testing confirmed at least metric invariance across various groups. Conclusions: The Chinese version of the SI-Bord demonstrates strong validity and reliability as a tool for screening for core BPD symptoms among Chinese university students. Further studies are encouraged to evaluate the validity of the SI-Bord across diverse groups, including age, socioeconomic status, and geographic regions. Applying it in clinical BPD samples will further enhance its utility across Chinese populations.

University students from diverse sexual orientations encounter specific mental health challenges due to academic demands, minority stress, and societal stigma; however, research focusing on these issues is still scarce in Southeast Asia. This research aimed to examine the mental health outcomes of heterosexual and sexuality diverse students in Thailand, concentrating on both negative aspects—such as depression, anxiety, and perceived stress—and positive aspects—like resilience, inner strength, and perceived social support. A cross-sectional survey was performed with 442 university students aged between 20 and 30, employing validated self-report instruments. Statistical methods, including t-tests and multiple regression analyses, were used to evaluate differences and relationships between sexual orientation and mental health outcomes while controlling for confounding variables. The findings revealed that sexuality diverse students showed notably higher levels of depression (B = 0.115, p < .05) and lower perceived social support (B = -0.10, p < .05) when compared to their heterosexual counterparts. Nevertheless, there were no significant differences found in anxiety, perceived stress, resilience, or inner strength. Perceived social support proved to be a crucial protective factor, with greater levels linked to reduced depression, anxiety, and perceived stress (p < .01). These results underscore the necessity for inclusive university policies, specific mental health interventions, and peer and family support initiatives to enhance the well-being of sexuality diverse students in Thailand.
