Prevalence and underlying factors of depressive disorders among PhD students: a mixed-method study in the Indian context

Abstract

PurposeThis study estimated the prevalence of depressive disorders among PhD students and analyzed the underlying factors in the Indian context.Design/methodology/approachThe authors utilized an “Integrative framework” and a mixed-method approach involving survey and in-depth interviews. The survey was conducted among 240 PhD students using multistage cluster sampling in two public universities of Kerala, India. Data were collected using a self-administered Patient Health Questionnaire-9. In-depth interviews were conducted among 12 students using semi-structured interview guide. Multinomial regression and thematic analyses were undertaken to examine the factors associated with depressive disorders.FindingsAbout 31.7, 41.7, 17.9, 6.7 and 2.1% had no/minimal, mild, moderate, moderately severe and severe depressive disorders, respectively. Students belonging to economically weaker section (OR = 3.06; 95% CI = 1.32–7.12), having limited knowledge of local language (OR = 4.24; 95% CI = 1.00–17.95) and earning less than INR 20,000/month (OR = 2.36; 95% CI = 1.12–5.00) were more likely to report moderate to severe depressive disorders. In addition, thematic analyses of interviews found that financial hardship, disagreement between student-supervisor, compromised students' support services and an uncertain job market were the key factors affecting the mental health of students and inhibiting academic performance.Originality/valueThis study adds to the existing literature by examining the prevalence and underlying factors of depressive disorders among doctoral students in the Indian context. The results of this study can act as a guide for universities and educational regulatory bodies to address the burgeoning issue of depressive disorders among research students in India.

Internet Addiction, Symptoms of Anxiety, Depressive Symptoms, Stress Among Higher Education Students During the COVID-19 Pandemic

“…Slovak students also reported more depression than anxiety, which is in line with the results revealed by Hajduk et al ( 57 ). In comparison, a similar prevalence was observed among Indian doctoral students (26.7%) ( 86 ), Chinese students (15.8%) ( 87 ), and Korean students (14%) ( 88 ), while a higher prevalence was observed among students from Germany (37%) ( 89 ), Bangladesh (48.8%) ( 90 ), and Malaysia (33.8%) ( 91 ). The mean score was 6.34 for Czech students and 5.77 for Slovak students, indicating mild depressive symptoms.…”

A holistic model of resources to enhance the doctoral student's well-being

“…This includes online informal mentoring groups, supervisory emotional and technical assistance, and inspiring doctoral students that increase their sense of self-determination. At the exosystem level, institution resources and policies, could create and support the students by increasing access to research facilities and equipment, increasing funding opportunities for the students like stipends and research grants, providing intensive coursework (Skopek et al, 2022), increasing transparency in the doctoral education regulations (McCray and Joseph-Richard, 2021), affording scholarship opportunities and organizing professional development workshops on advanced statistics (Sin et al, 2021;Waight and Giordano, 2018), research methodology (Caliskan and Holley, 2017) and writing for high-impact journal publications (LT et al, 2022). The requirements of the doctoral program, which include presenting research output at conferences, writing for high-impact journal publications, managing the research fund along with personal expenses and developing the necessary research competencies, must be well communicated to the students by the universities in their doctoral regulations.…”

Stimulating Creativity Through Cognitive Symmetry Breaking: Tagorean Theory of Sustainable Human Development

“…In recent years, there has been growing interest in the relevance of the Tagorean approach in the Indian education system. The Indian education system is one of the largest in the world, but it has faced several challenges such as high drop-out rates [11][12][13][14], self-harm [15][16][17], a lack of quality education [18][19][20][21][22], and a focus on rote learning rather than critical thinking. In this context, the Tagorean approach has gained attention, with some scholars arguing that it offers a viable alternative to the dominant approaches in the conventionally practised education system.…”
