Work organization and mental health problems in PhD students
Open accessPublished version of a preprint
Abstract
Research policy observers are increasingly concerned about the potential impact of current academic working conditions on mental health, particularly in PhD students. The aim of the current study is threefold. First, we assess the prevalence of mental health problems in a representative sample of PhD students in Flanders, Belgium (N = 3659). Second, we compare PhD students to three other samples: (1) highly educated in the general population (N = 769); (2) highly educated employees (N = 592); and (3) higher education students (N = 333). Third, we assess those organizational factors relating to the role of PhD students that predict mental health status. Results based on 12 mental health symptoms (GHQ-12) showed that 32% of PhD students are at risk of having or developing a common psychiatric disorder, especially depression. This estimate was significantly higher than those obtained in the comparison groups. Organizational policies were significantly associated with the prevalence of mental health problems. Especially work-family interface, job demands and job control, the supervisor’s leadership style, team decision-making culture, and perception of a career outside academia are linked to mental health problems.

Written from the paper’s full text.
TL;DR
In a representative Flemish sample of 3,659 PhD students, 32% screened at GHQ4+ for risk of a common psychiatric disorder, and 51% reported at least two GHQ-12 symptoms. Mental health problems were more prevalent than in three comparison groups and were linked to work-family conflict, job demands and control, supervisor leadership, team decision-making, and career perceptions.
Key findings
- Prevalence among PhD students was 51% for GHQ2+, 40% for GHQ3+, and 32% for GHQ4+. The most common symptoms included constant strain, unhappiness/depression, sleep loss from worry, difficulty overcoming problems, and reduced enjoyment of daily activities.
- Compared with the highly educated general population, PhD students had adjusted risk ratios of 1.90 for GHQ2+, 2.26 for GHQ3+, and 2.43 for GHQ4+. Compared with highly educated employees, the corresponding ratios were 2.02, 2.56, and 2.84; compared with higher education students, they were 1.53, 1.63, and 1.85.
- Work-family conflict was the strongest predictor in relative-weight terms (34.1% for GHQ2+ and 29.8% for GHQ4+). Job demands had ORs of 1.896 for GHQ2+ and 1.651 for GHQ4+; job control had ORs of 0.784 and 0.631; family-work conflict had ORs of 1.206 and 1.296; work-family conflict had ORs of 1.521 and 1.522.
- Inspirational supervisor leadership was associated with lower odds (OR 0.868 for GHQ2+, 0.908 for GHQ4+), laissez-faire leadership with higher distress odds (OR 1.084 for GHQ2+), and closed team decision-making with higher GHQ4+ odds (OR 1.205). No discipline differences were found; executing-phase students had lower odds than initiating-phase students, and positive career perceptions inside or outside academia were associated with better mental health.
Methods
- Cross-sectional 2013 web survey of junior researchers at all Flemish universities; the analytic sample was 3,659 PhD students from a total population of 12,191, with a 33% response rate. Selective non-response analyses showed slightly more women, younger respondents, social scientists, and Belgians than in the total population.
- Comparison groups came from Belgian Health Interview Surveys: highly educated general population (N = 769), highly educated employees (N = 592), and higher education students (N = 333, pooled across 2001, 2004, 2008, and 2013).
- Mental health was measured with the GHQ-12 using GHQ2+, GHQ3+, and GHQ4+ thresholds. Analyses included adjusted risk ratios controlling for age and gender, and logistic regressions producing odds ratios, relative weights, and Nagelkerke R² values (0.202 for GHQ2+ and 0.204 for GHQ4+), with controls for gender, age, partner, and children.
Limitations
- The paper states that the cross-sectional design prevents causal conclusions, including possible self-selection or the alternative that distressed PhD students evaluate their environment more negatively.
- The paper also states that findings may be specific to Flanders, that financial conditions differ from countries where PhD students face more financial worries, and that GHQ4+ is a probabilistic screening measure rather than a clinical diagnosis.
- Evident from the text: the 33% response rate and selective non-response may affect prevalence estimates; all mental health measures are self-reported; and the higher education student comparison group was pooled across multiple survey years.

“Studies almost unanimously report a consistent link between high job demands and emotional exhaustion and depressive feelings (e.g.De Lange et al., 2004).”
§ Work organization and mental health problems in PhD students > 2.3.1. Work context Work roles and workload demands, job control, support by peers or supervisors, and job insecurity are the most frequently examined characteristics of the work context (e.g.WHO, 2010).Studies almost unanimously report a consistent link between high job demands and emotional exhaustion and depressive feelings (e.g.De Lange et al., 2004).While PhD students clearly have different roles, tasks and responsibilities to fulfill than regular employees do, we believe that there are a series of common psychological characteristics that make it useful to study PhD students' roles through the lens of the organizational context in which they perform their study and research work.For reasons of clarity, we use the commonly accepted terminology in occupational health psychology, with the clear understanding that work-related aspects, such as job demands, refer to the demands experienced by students in their specific study and research roles.Job demands are those physical, social or organizational aspects of the job that require sustained physical or mental effort.Job control on the other hand, refers to control over the work environment, more specifically over the pace of work, the timing of breaks, or the use of skills (Karasek and Theorell, 1990).Most, but not all, occupational health studies find significant emotional costs when job control is low (De Lange et al., 2004;Vanroelen et al., 2009).Existing research on occupational stress in university staff has consistently found work load to be one of the main causes of stress (e.g.Gillespie et al., 2001;Winefield et al., 2003;Kinman, 2001;Kinman et al., 2006;Tytherleigh et al., 2005;Biron et al., 2008;Sun et al., 2011;Mark and Smith, 2012;Boyd et al., 2011). For PhD students, the balance between demands and control might be different across scientific disciplines as it entails differences in academic practice.Writing a doctoral dissertation in the natural sciences may entail working as part of a large team within a specific well-defined project, and operating with pre-defined, transparent quantitative publication criteria (Larivière, 2012).For PhD students in the humanities and social sciences, establishing one's own research idea (and thus often working in isolation) may constitute more of a challenge in terms of perseverance, given also the lack of consensus over the quality criteria in these fields (Long and Fox, 1995).

The Correlational analyses section reports that higher job demands predicted increases in both depression and emotional exhaustion over time. The paper therefore supports the link, but its findings do not establish the claim that studies report it almost unanimously; the Introduction describes mixed support for the broader high-strain hypothesis. The supplied passages give no page numbers. (LLM, conf=0.84)

The Correlational analyses section (page unavailable) reports that greater supervisor support was associated with lower emotional exhaustion over time. It does not report that support affected anxiety or job tension; for job satisfaction, the reported direction runs from satisfaction to later supervisor support, not the reverse. (LLM, conf=0.88)

“As prior research has shown that both employment frustration (not finding the work one wants) and reward frustration (e.g.poor promotion prospects) have an impact on self-reported mental health (e.g.Castro et al., 2010), the current study will also examine the career prospects of PhD students.”

“In a Finnish study of 383 PhD students, Stubb et al. (2011) found that 44% reported the academic community as a source of empowerment, enthusiasm and inspiration, while 56% experienced it as a source of burden.”
§ Work organization and mental health problems in PhD students > 2.3.1. Work context Work roles and workload demands, job control, support by peers or supervisors, and job insecurity are the most frequently examined characteristics of the work context (e.g.WHO, 2010).Studies almost unanimously report a consistent link between high job demands and emotional exhaustion and depressive feelings (e.g.De Lange et al., 2004).While PhD students clearly have different roles, tasks and responsibilities to fulfill than regular employees do, we believe that there are a series of common psychological characteristics that make it useful to study PhD students' roles through the lens of the organizational context in which they perform their study and research work.For reasons of clarity, we use the commonly accepted terminology in occupational health psychology, with the clear understanding that work-related aspects, such as job demands, refer to the demands experienced by students in their specific study and research roles.Job demands are those physical, social or organizational aspects of the job that require sustained physical or mental effort.Job control on the other hand, refers to control over the work environment, more specifically over the pace of work, the timing of breaks, or the use of skills (Karasek and Theorell, 1990).Most, but not all, occupational health studies find significant emotional costs when job control is low (De Lange et al., 2004;Vanroelen et al., 2009).Existing research on occupational stress in university staff has consistently found work load to be one of the main causes of stress (e.g.Gillespie et al., 2001;Winefield et al., 2003;Kinman, 2001;Kinman et al., 2006;Tytherleigh et al., 2005;Biron et al., 2008;Sun et al., 2011;Mark and Smith, 2012;Boyd et al., 2011). For PhD students, the balance between demands and control might be different across scientific disciplines as it entails differences in academic practice.Writing a doctoral dissertation in the natural sciences may entail working as part of a large team within a specific well-defined project, and operating with pre-defined, transparent quantitative publication criteria (Larivière, 2012).For PhD students in the humanities and social sciences, establishing one's own research idea (and thus often working in isolation) may constitute more of a challenge in terms of perseverance, given also the lack of consensus over the quality criteria in these fields (Long and Fox, 1995).

“The GHQ is a screening instrument to identify psychological distress and potential cases of common psychiatric disorder (especially depression), leaving the task of diagnosing actual disorder to a psychiatric interview (McDowell, 2006).”
§ Work organization and mental health problems in PhD students > 3.3.1. Mental health problems Mental health problems were measured using the 12-item version of the General Health Questionnaire (GHQ) (Goldberg, 1972;Goldberg and Williams, 1988).The GHQ is a screening instrument to identify psychological distress and potential cases of common psychiatric disorder (especially depression), leaving the task of diagnosing actual disorder to a psychiatric interview (McDowell, 2006).The GHQ is the most frequently used scale worldwide to tap into psychological well-being (e.g.Boyd et al., 2011).The internal consistency of the GHQ-12 was 0.88 in Sample 1 and 0.87 in Sample 2. The 12 GHQ items are presented in Table 3. GHQ items explore the respondent's experience in recent weeks compared to his or her usual experience.Response categories are item-specific but all responses are given on 4-point Likert-type scales.We adopt the GHQ scoring method, which uses a bimodal 0-0-1-1 scheme (to score subsequent response categories), conceiving the respondent's total number of 1 scores over the 12 items as an indication of the number of symptoms experienced.In order to determine that a person has a mental health problem, (s)he should experience a minimum number of symptoms.The literature reports substantial variation in the minimum number of symptoms to be considered (Goldberg et al., 1997).In the current study we opt for the GHQ2+ (presence of at least 2 symptoms), indicating psychological distress.We also assess the GHQ4+ (presence of at least 4 symptoms), indicating the risk of having or developing a common psychiatric disorder (especially depression) (Goldberg, 1972;Goldberg and Williams, 1988).A worldwide study on mental health by the World Health Organization suggests using the GHQ4+ if the mean GHQ score in the sample is higher than 2.70 (Goldberg et al., 1998).In Sample 1, the mean GHQ score is 2.84.However, for reasons of comparison with other studies on mental health in the university sector (see Table 2), we also include the GHQ3+ (presence of at least 3 symptoms) when calculating prevalence. Preliminary multigroup confirmatory factor analyses across both samples in our study attested to the stability of the measurement model underlying the GHQ.

GHQ items explore the respondent's experience in recent weeks compared to his or her usual experience.Response categories are item-specific but all responses are given on 4-point Likert-type scales.We adopt the GHQ scoring method, which uses a bimodal 0-0-1-1 scheme (to score subsequent response categories), conceiving the respondent's total number of 1 scores over the 12 items as an indication of the number of symptoms experienced.In order to determine that a person has a mental health problem, (s)he should experience a minimum number of symptoms.The literature reports substantial variation in the minimum number of symptoms to be considered (Goldberg et al., 1997).In the current study we opt for the GHQ2+ (presence of at least 2 symptoms), indicating psychological distress.We also assess the GHQ4+ (presence of at least 4 symptoms), indicating the risk of having or developing a common psychiatric disorder (especially depression) (Goldberg, 1972;Goldberg and Williams, 1988).A worldwide study on mental health by the World Health Organization suggests using the GHQ4+ if the mean GHQ score in the sample is higher than 2.70 (Goldberg et al., 1998).In Sample 1, the mean GHQ score is 2.84.However, for reasons of comparison with other studies on mental health in the university sector (see Table 2), we also include the GHQ3+ (presence of at least 3 symptoms) when calculating prevalence. Preliminary multigroup confirmatory factor analyses across both samples in our study attested to the stability of the measurement model underlying the GHQ.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-10-10, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-10 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Cited sources are checked with a language model’s help (gpt-6-sol).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
