## Executive GIST (TL;DR)
- This secondary analysis used the publicly available **Nature Careers 2025 Global PhD Survey** dataset with responses from 3,785 PhD students across 107 countries to examine how supervisor support relates to overall PhD satisfaction. - The study distinguishes two broad components of supervision: **supervisory contact frequency** (amount of contact) and the **quality of supervisor support**, which was disaggregated into **supervisory relationship quality**, **research guidance**, **career guidance**, and **supervisor career support**. - Ordinary least squares (OLS) regression served as the baseline estimation method, with ordered logit, binary logit, alternative-outcome models, and extended-control checks used for robustness. - In descriptive and reduced models, **contact frequency** showed a positive association with overall PhD satisfaction, but this association became weak and unstable after adding the support-quality dimensions. - By contrast, **supervisory relationship quality**, **research guidance**, **career guidance**, and **career support** remained positively and consistently associated with overall PhD satisfaction across model specifications. - These quality dimensions were also associated with whether students reported that their doctoral experience met their initial expectations. - The authors conclude that the **content and developmental quality of supervisory interaction** matter more than contact time alone for PhD students’ learning experience. - The study contributes by (1) separating contact frequency from support quality, (2) disaggregating support into multiple dimensions, and (3) providing global evidence using a large, publicly available dataset to inform institutional efforts to strengthen supervision, feedback, and career development support. - Data availability, funding, and competing interests: data were publicly available via Figshare, no specific funding was received, and authors declared no competing interests.

Using publicly available data from 3,785 PhD students in 107 countries in the Nature Careers 2025 Global PhD Survey, this study examines how supervisory contact frequency, relationship quality, research guidance, career guidance, and career support are associated with overall PhD satisfaction. Ordinary least squares regression provides the baseline estimates, supplemented by ordered logit and binary logit models and alternative-outcome and extended-control checks. Contact frequency is positively associated with satisfaction in descriptive and reduced models, but its independent association becomes weak and unstable after support-quality dimensions are introduced. In contrast, supervisory relationship quality, research guidance, career guidance, and career support remain positively and consistently associated with satisfaction across model specifications. These dimensions are also associated with whether students perceive their doctoral experience as meeting their initial expectations. The findings indicate that the quality and developmental content of supervisory interaction matter more than contact time alone. By disaggregating supervisory support, this study contributes global evidence to doctoral education research and informs institutional efforts to strengthen supervision quality, feedback, and career development support. ## Figures ![Fig 1](https://journals.plos.org/plosone/article/figure/image?size=inline&id=10.1371/journal.pone.0357413.g001) ![Table 4](https://journals.plos.org/plosone/article/figure/image?size=inline&id=10.1371/journal.pone.0357413.t004) ![Table 5](https://journals.plos.org/plosone/article/figure/image?size=inline&id=10.1371/journal.pone.0357413.t005) ![Table 1](https://journals.plos.org/plosone/article/figure/image?size=inline&id=10.1371/journal.pone.0357413.t001) ![Table 2](https://journals.plos.org/plosone/article/figure/image?size=inline&id=10.1371/journal.pone.0357413.t002) ![Table 3](https://journals.plos.org/plosone/article/figure/image?size=inline&id=10.1371/journal.pone.0357413.t003) ![Fig 1](https://journals.plos.org/plosone/article/figure/image?size=inline&id=10.1371/journal.pone.0357413.g001) ![Table 4](https://journals.plos.org/plosone/article/figure/image?size=inline&id=10.1371/journal.pone.0357413.t004) ![Table 5](https://journals.plos.org/plosone/article/figure/image?size=inline&id=10.1371/journal.pone.0357413.t005) ![Table 1](https://journals.plos.org/plosone/article/figure/image?size=inline&id=10.1371/journal.pone.0357413.t001) ![Table 2](https://journals.plos.org/plosone/article/figure/image?size=inline&id=10.1371/journal.pone.0357413.t002) ![Table 3](https://journals.plos.org/plosone/article/figure/image?size=inline&id=10.1371/journal.pone.0357413.t003) **Citation:** Li NY, Zhang H, Wang J, Ye M (2026) How does supervisor support shape PhD students’ learning experience?

Its quality is closely related not only to the supply of highly trained talent for universities and research institutions, but also to knowledge production, academic innovation, and the long-term development of professional labour markets. In recent years, PhD students’ learning experience has become an increasingly important topic in higher education research. Compared with undergraduate and taught postgraduate education, doctoral learning is more prolonged, individualized, and uncertain. PhD students are expected to complete research training, dissertation writing, academic publishing, career decision-making, and identity transition over an extended period. Their evaluation of the doctoral experience is therefore shaped not only by research outputs or coursework, but also by the support relationships embedded in the training process. Within doctoral education, supervisors constitute one of the most important sources of institutional support. Supervisors influence PhD students’ research directions, methodological choices, and dissertation progress. They also shape students’ overall perceptions of the doctoral experience through feedback practices, communication quality, career advice, and access to development opportunities. Existing English-language studies have widely shown that supervisor support is closely associated with PhD students’ satisfaction, research engagement, mental health, and academic persistence [[1](https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0357413#pone.0357413.ref001)–[3](https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0357413#pone.0357413.ref003)]. This body of research has moved doctoral education studies beyond a narrow focus on completion rates and research outputs toward a stronger concern with students’ lived experiences during doctoral training. Nevertheless, existing discussions of supervisor support still require further refinement. On the one hand, many studies treat supervisor support as an overall construct, which may obscure differences among its internal dimensions. The support PhD students receive from supervisors is not limited to research guidance; it also includes relational support, career guidance, and encouragement for diverse career pathways. On the other hand, the distinction between supervisory contact frequency and the quality of supervisor support has not been sufficiently clarified. In doctoral training practice, increasing the amount of supervisor–student contact is often regarded as a direct way to improve supervision quality. Yet contact frequency does not necessarily imply effective support. Frequent contact may provide timely feedback, but it may also involve more intensive administrative communication, progress pressure, or formalized interaction. What may matter more for PhD students’ learning experience is not the amount of contact itself, but whether the interaction contains clear, trustworthy, and development-oriented support. This issue is particularly relevant in the current context of doctoral education. As the career destinations of PhD graduates become increasingly diverse, doctoral training no longer serves only traditional academic career pathways. PhD students need not only guidance on dissertation writing and research methods, but also opportunities to discuss academic, non-academic, and cross-sector career development. Whether supervisors are willing to discuss career issues openly, accept non-academic career choices, provide relevant advice, and encourage students to participate in career development activities has become an important component of how PhD students evaluate their training experience. If supervisor support continues to be understood merely as academic supervision, it becomes difficult to explain the complexity of contemporary doctoral learning experiences. Against this background, this study conducts a secondary analysis of the publicly available anonymized data from the Nature Careers 2025 Global PhD Survey [[4](https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0357413#pone.0357413.ref004)]. Drawing on responses from 3,785 PhD students across 107 countries, it examines how supervisor support is associated with PhD students’ learning experience. Overall PhD satisfaction is used as the main outcome variable. Supervisor support is divided into two dimensions: supervisory contact frequency and the quality of supervisor support. The latter is further specified as supervisory relationship quality, research guidance, career guidance, and supervisor career support. Methodologically, ordinary least squares regression is used as the baseline model, supplemented by ordered logit models, binary logit models, alternative outcome models, and models with extended control variables for robustness checks. The central purpose of this study is not simply to verify whether supervisor support matters, but to compare the relative explanatory roles of supervisory contact frequency and support quality. The empirical results show that supervisory contact frequency is significantly associated with overall PhD satisfaction in simpler models. However, after supervisory relationship quality, research guidance, career guidance, and career support are included, the independent role of contact frequency is no longer consistently significant. By contrast, supervisory relationship quality, research guidance, career guidance, and career support remain positively and robustly associated with overall PhD satisfaction across different model specifications. These findings suggest that PhD students’ learning experience is more consistently associated with the quality of supervisor support than with contact frequency itself. This study makes three main contributions. First, at the level of research question, it distinguishes supervisory contact frequency from the quality of supervisor support, thereby addressing whether increasing supervisor–student contact is sufficient to improve doctoral learning experience. Second, in terms of variable construction, it disaggregates supervisor support into multiple dimensions, including supervisory relationship, research guidance, career guidance, and career support, rather than treating supervisor support as a single undifferentiated construct. Third, empirically, it uses a global publicly available PhD survey dataset to conduct systematic model-based analysis, providing new evidence for understanding the relationship between supervisor support and doctoral learning experience across diverse doctoral training contexts. Accordingly, the study addresses three research questions. **RQ1:** How is supervisory contact frequency associated with overall PhD satisfaction? **RQ2:** How are supervisory relationship quality, research guidance, career guidance, and supervisor career support associated with overall PhD satisfaction? **RQ3:** Does supervisory contact frequency retain an independent association with overall PhD satisfaction after support-quality dimensions are taken into account, and do the observed patterns remain stable across alternative model specifications and outcome measures? ## Literature review PhD students’ learning experience is commonly understood as their overall experience of research training, academic interaction, institutional support, and career development. It is often reflected in indicators such as satisfaction, research engagement, mental health, academic persistence, and career expectations. Recent studies suggest that the doctoral experience is not determined solely by individual ability, but is embedded in multiple conditions, including supervisory relationships, research communities, peer support, departmental environment, and life pressures. Dericks et al. [[1](https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0357413#pone.0357413.ref001)] found that the quality of supervisors, departments, and peers all affected PhD student satisfaction, with supervisor supportiveness playing a particularly important role. Corcelles-Seuba et al. [[5](https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0357413#pone.0357413.ref005)], Rönkkönen et al. [[6](https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0357413#pone.0357413.ref006)], and Cao et al. [[7](https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0357413#pone.0357413.ref007)] further showed that supervisor support and research community support contribute to PhD students’ research engagement and academic involvement. Negative doctoral experiences are also frequently associated with psychological stress, burnout, dropout intentions, and the risk of interrupting doctoral studies [[8](https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0357413#pone.0357413.ref008)–[10](https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0357413#pone.0357413.ref010)]. Supervisor support is not a single behaviour, but a combination of relational, academic, and developmental support. Relational support involves trust, respect, communication, and emotional availability; research guidance concerns topic selection, methodology, dissertation feedback, and academic norms; career support involves career discussions, understanding of non-academic pathways, and access to development opportunities. Wang et al. [[2](https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0357413#pone.0357413.ref002)] distinguished the roles of high-quality supervision and peer support in shaping PhD students’ research experience, while emphasizing that supervisor support remains a core resource in doctoral research training. From a multicultural perspective, Guarimata-Salinas et al. [[11](https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0357413#pone.0357413.ref011)] argued that contemporary doctoral supervisors are no longer merely dissertation managers, but increasingly perform educational, relational, and developmental functions. Mavrogalou-Foti et al. [[12](https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0357413#pone.0357413.ref012)] also found a significant association between supervisory relationships and doctoral students’ mental health outcomes. Taken together, these studies suggest that supervisor support should be disaggregated into specific dimensions rather than treated as a broad and undifferentiated construct [[3](https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0357413#pone.0357413.ref003),[13](https://journals.plos
