Unraveling psychological burden: the interplay of socio-economic status, anxiety sensitivity, intolerance of uncertainty, and stress in first-year medical students

Abstract

Background

The escalating prevalence of mental health issues among young adults, set against the backdrop of a global healthcare system under pressure, underscores the necessity for cultivating a resilient medical workforce. This study investigates the influence of socio-economic status (SES) on psychological well-being, with a particular focus on Anxiety Sensitivity (AS) and Intolerance of Uncertainty (IU) among first-year medical students. Understanding the psychological dimensions affecting medical students is crucial for fostering a future medical workforce that is both capable and mentally healthy.

Methods

This research involved 321 first-year medical students, evaluated using the Perceived Stress Questionnaire (PSQ), Anxiety Sensitivity Index (ASI), the Intolerance of Uncertainty Scale (UI-18), and the Student Self-Efficacy Scale (SSE), alongside socio-economic categorization. Employing descriptive statistics, ANOVA, and correlation analyses, the study aimed at elucidating the SES impact on AS and IU, among other psychological constructs.

Results

The analysis revealed significant SES-related differences, especially in the realms of Anxiety Sensitivity and Intolerance of Uncertainty. Notably, ASI_C (cognitive concerns) exhibited strong positive correlations with both UI_A (reduced ability to act due to IU) (Pearson’s r = 0.562, p < 0.001) and UI_B (burden due to IU) (Pearson’s r = 0.605, p < 0.001), highlighting the link between cognitive aspects of anxiety and uncertainty intolerance. Furthermore, UI_C (vigilance due to IU) was significantly associated with SES (F(4, 316) = 2.719, p = 0.030, η² = 0.033), pointing to the complex ways in which socio-economic factors modulate responses to uncertainty. Self-efficacy emerged as a significant counterbalance, showing protective associations against the adverse effects of heightened Anxiety Sensitivity and Intolerance of Uncertainty.

Conclusion

Our findings indicate that lower socio-economic status is associated with higher levels of Anxiety Sensitivity and Intolerance of Uncertainty, which contribute to increased stress among first-year medical students. Additionally, Self-Efficacy emerged as a significant protective factor, mitigating the expressions of AS and IU. Although medical faculties cannot change SES characteristics within their student body, recognizing its impact allows for the development of tailored support systems to address the unique challenges faced by students from diverse socio-economic backgrounds. This study underscores the necessity of considering social diversity, particularly regarding AS and IU characteristics, to foster a supportive and effective medical education environment with an outlook on sustainable mental health in a demanding work context.
