4. Discussion
This study compared mental health outcomes between straight and sexuality-diverse university students in Thailand. It explored positive factors such as inner strength, resilience, and perceived social support, while also assessing negative outcomes like depression, anxiety, and perceived stress. The study identified mental health disparities between the groups, aligning with global research on LGBTQ+ well-being and highlighting unique challenges faced by sexuality-diverse students in Southeast Asia.
Interestingly, no significant difference in resilience was found between straight and sexuality-diverse students, suggesting similar coping abilities despite mental health disparities. Resilience, a key protective factor against perceived stress, anxiety, and depression [
22], helps individuals adapt to adversity. This aligns with research indicating that LGBTQ+ individuals benefit from social support networks that enhance resilience [
23,
24]. In Thailand, LGBTQ+ student groups and community resources likely contribute to this resilience [
25]. However, societal and familial pressures may undermine confidence in identity, highlighting the need for interventions to strengthen self-esteem and identity development [
26]. Resilience was linked to lower anxiety, depression, and perceived stress, yet sexuality-diverse students may experience reduced resilience due to minority stress and internalized stigma, weakening its protective effects [
4].
The findings support that perceived social support played a crucial role in mental health, with higher support linked to lower anxiety, depression, and perceived stress, as well as greater resilience and inner strength. Social support helps mitigate minority stress [
27,
28]. Yet sexuality-diverse students in Thailand may struggle to access it due to traditional family structures. Alternative sources, such as peer networks and spirituality, may aid resilience, though further research is needed [
29]. Cultural expectations around family, religion, and societal roles can create challenges for LGBTQ+ individuals [
5], underscoring the need for culturally sensitive mental health interventions to foster supportive environments.
Sexuality-diverse students reported significantly higher depression levels than their straight peers, aligning with minority stress theory, which links stigma and discrimination to mental health challenges [
4,
30]. Despite Thailand’s reputation for LGBTQ+ tolerance, deep-rooted cultural norms uphold heteronormativity, contributing to alienation [
5]. While most parents in this study were supportive, some were not, reflecting the complex reality of acceptance. Research highlights the contrast between Thailand’s perceived inclusivity and the actual stigmatization faced by LGBTQ+ individuals, particularly in education [
31]. These societal pressures likely contribute to the heightened anxiety, depression, and stress observed among sexuality-diverse students [
26].
The findings revealed that sexuality diverse students reported lower levels of resilience and inner strength compared to their heterosexual peers. Resilience, which embodies an individual’s empowerment, self-assurance, and capacity to overcome life’s challenges [
32], seemed to be diminished among sexuality-diverse students. While this difference didn't reach statistical significance (p = .213,
Table 3), it signals a potential area for further exploration.
Sexuality-diverse students exhibited higher levels of internalized homophobia (IHP) than their straight peers, with 41.0% reporting low IHP, while 36.7% of straight students showed moderate-to-high levels (p = .001). They also held more positive attitudes toward sexual minorities (p < .001). Parental support varied significantly, with fewer sexuality-diverse students (38.1%) reporting supportive parents compared to straight students (46.9%, p < .001), while a greater proportion faced unsupportive parental attitudes (10.2% vs. 4.8%). These findings align with the psychological mediation framework, suggesting that stigma and discrimination diminish resilience and self-esteem, leading to poorer mental health outcomes [
33,
34].
Mental health disparities were evident, particularly in depression and perceived social support. Sexuality-diverse students reported significantly lower social support across all models (Model 1: B = -0.105, p = .024; Model 2: B = -0.118, p = .016; Model 3: B = -0.100, p = .045), possibly due to peer rejection, institutional discrimination, or internalized stigma [
6]. Sexual orientation also emerged as a significant predictor of depression (B = 0.115, p = .020), even after adjusting for demographic factors, reinforcing evidence that LGBTQ+ youth face heightened depression risks due to minority stress [
35]. While anxiety and stress differences were less pronounced, sexuality-diverse students consistently reported higher mean scores (Anxiety: 8.99 ± 5.17 vs. 8.75 ± 4.96; Depression: 4.81 ± 4.34 vs. 3.94 ± 3.70; Perceived stress: 18.42 ± 6.49 vs. 18.53 ± 5.99,
Table 3), reflecting the cumulative burden of navigating a heteronormative society.
Unlike previous research emphasizing discrimination’s negative effects [
14], this study highlights protective factors such as resilience and inner strength. Despite reporting lower perceived social support (p = .009,
Table 3), sexuality-diverse students exhibited resilience levels comparable to their straight peers, suggesting that coping strategies and community support may buffer the psychological effects of minority stress. These findings expand on previous studies by empirically demonstrating how variations in social support influence university students' mental health in Thailand [
31].
4.1. Implications
The findings of this research suggest that university students who identify as sexuality diverse face a greater risk of mental health disparities, especially depression and lower perceived social support, compared to their heterosexual counterparts. These disparities underscore the need for targeted mental health initiatives and policy measures that address the specific challenges faced by this group.
Given the heightened vulnerability of sexuality diverse students to depression and lower social support, universities and policymakers need to adopt targeted mental health interventions to address these disparities. Suggested initiatives include: Improving LGBTQ+ inclusive mental health services by educating mental health practitioners on LGBTQ+ cultural competence. Establishing peer mentorship programs to bolster social support networks for sexuality diverse students. Introducing family acceptance programs to inform families about the importance of supporting their LGBTQ+ children. Reinforcing anti-discrimination policies within universities to foster safer and more inclusive educational environments.
4.2. Limitations
1)The study's sample was limited to university students in Thailand, so the findings may not apply to the broader sexuality diverse population in different age groups, educational settings, or geographic regions. 2) The study relied on self-reported data, which may introduce bias due to social desirability or inaccurate recall. This could lead to participants underreporting or overreporting mental health symptoms, resilience, or perceived social support, potentially affecting the accuracy of the findings. 3) Cultural factors unique to Thailand, such as the influence of Buddhism or specific societal norms, may have impacted the experiences of sexuality diverse individuals in ways not fully captured in the study. To gain a more comprehensive understanding of the mental health experiences of sexuality diverse individuals in Thailand, future research should consider longitudinal designs, larger and more diverse samples, and the inclusion of additional variables.
