<p>Prevalence and associated factors of depression and anxiety among doctoral students: the mediating effect of mentoring relationships on the association between research self-efficacy and depression/anxiety</p>

Abstract

PurposeAlthough the mental health status of doctoral students deserves attention, few scholars have paid attention to factors related to their mental health problems. We aimed to investigate the prevalence of depression and anxiety in doctoral students and examine possible associated factors. We further aimed to assess whether mentoring relationships mediate the association between research self-efficacy and depression/anxiety.MethodsA cross-sectional study was conducted among 325 doctoral students in a medical university. The Patient Health Questionnaire 9 and Generalized Anxiety Disorder 7 scale were used to assess depression and anxiety. The Research Self-Efficacy Scale was used to measure perceived ability to fulfill various research-related activities. The Advisory Working Alliance Inventory-student version was used to assess mentoring relationships. Linear hierarchical regression analyses were performed to determine if any factors were significantly associated with depression and anxiety. Asymptotic and resampling methods were used to examine whether mentoring played a mediating role.ResultsApproximately 23.7% of participants showed signs of depression, and 20.0% showed signs of anxiety. Grade in school was associated with the degree of depression. The frequency of meeting with a mentor, difficulty in doctoral article publication, and difficulty in balancing work–family–doctoral program was associated with both the level of depression and anxiety. Moreover, research self-efficacy and mentoring relationships had negative relationships with levels of depression and anxiety. We also found that mentoring relationships mediated the correlation between research self-efficacy and depression/anxiety.ConclusionThe findings suggest that educational experts should pay close attention to the mental health of doctoral students. Active strategies and interventions that promote research self-efficacy and mentoring relationships might be beneficial in preventing or reducing depression and anxiety.

Association Between Anxiety Symptoms and Problematic Smartphone Use Among Chinese University Students: The Mediating/Moderating Role of Self-Efficacy

“…Self-efficacy, as one of the most important positive psychological qualities, has become a plastic internal psychological resource and can serve as a buffer against mental disorders ( 41 – 43 ). CL Liu et al demonstrated that self-efficacy was negatively correlated with the levels of both depression and anxiety among doctoral students ( 44 ). Self-efficacy training has been confirmed effective in reducing mental problems, such as anxiety and depression ( 45 ).…”

It Must have been Burnout: Prevalence and Related Factors among Spanish PhD Students

“…TMMS-24: Trait Meta-Mood Scale. Burnout in Spanish PhD Students 9 Liu et al, 2019). Following this line of work, we hypothesized that burnout can be a reaction to this prolonged exposure to stress.…”

“…One way to do this could be to explore the management styles or dimensions that form the relationship. A possible starting point is the study by Liu et al (2019). These authors used a 30 item measure to assess the strength of the mentoring relationship in three dimensions: Rapport (encouragement, respect, and interpersonal warmth), apprenticeship (the degree to which the advisor teaches the advisee about professional work), and task focus (the degree to which the advisor facilitates the advisee's progress through the graduate program).…”

La carrera investigadora en arqueología y su impacto en la salud mental de los investigadores predoctorales

“…Diferentes investigaciones señalan el papel fundamental de las relaciones dentro del entorno académico a la hora de condicionar la experiencia de los doctorandos (Corcelles et al 2019), siendo especialmente relevante el papel de los directores de tesis (Evans et al 2018; González-Ocampo y Castelló 2019; Liu et al 2019). Una buena dirección influye directamente en el bienestar de un doctorando y, por tanto, puede condicionar su permanencia o no dentro del sistema académico una vez acabada la tesis, por lo que es una variable importante a considerar en un estudio como el nuestro.…”
