Mediating role of self-efficacy in the association between multidimensional resource support and postdoctoral job satisfaction

Why this matters to working scientists and the public

Behind many scientific breakthroughs are postdoctoral researchers—PhD graduates in temporary positions who drive experiments, write papers, and mentor students. Yet their own happiness at work often receives little attention. This study asks a simple but crucial question: when do postdocs feel satisfied with their jobs, and how does the support they receive—from paychecks to mentoring—shape that satisfaction through their own confidence in their abilities?

Different kinds of help at work

The researchers focus on four broad forms of help that postdocs can receive. First is support from supervisors, including how often they communicate and how well they respond to needs. Second is financial support, mainly satisfaction with salary and compensation. Third is organizational support, such as mental health services, work–life balance, training, job security, safety, and a culture of inclusion. Fourth is career development support, which covers optimism about future job prospects and chances for promotion. Together, these make up a rich picture of the environment surrounding early-career researchers.

A global snapshot of postdoc life

The team analyzed responses from 3,838 postdocs who completed Nature’s 2023 global postdoc survey, spanning 93 countries and a wide range of disciplines. Overall, postdocs rated their job satisfaction moderately high on a seven-point scale, suggesting many still find meaning and enjoyment in their work. But there were striking gaps in how well different needs were met. Organizational conditions—such as training access or feeling safe at work—tended to score relatively well. In contrast, pay and especially career support lagged behind. Many postdocs felt poorly compensated, worried about their future, and were dissatisfied with promotion opportunities, reflecting intense competition for permanent academic jobs.

How support and confidence work together

Using regression and mediation analyses, the authors showed that all four support types are linked to higher job satisfaction: more helpful supervisors, better pay, stronger organizational backing, and clearer career pathways each predict more content postdocs, even after accounting for age, gender, discipline, and whether someone works in their home country. Younger postdocs and those staying in their home country tended to be more satisfied. A smaller subsample of Chinese postdocs revealed broadly similar trends, although supervisor support was less clearly tied to satisfaction once other factors were considered, hinting at cultural or structural differences in how mentorship is experienced.

The quiet power of self-belief

A key innovation of the study is its focus on self-efficacy—the belief that one can succeed and make meaningful accomplishments. The authors found that better support at work boosts this sense of personal capability, which in turn lifts job satisfaction. In statistical terms, self-efficacy partially carries the positive effects of supervisor, financial, organizational, and career development support into higher overall contentment. For example, generous organizational resources not only make daily tasks easier; they also help postdocs feel more competent and effective, and that stronger self-belief is closely tied to feeling satisfied with the job.

What institutions and policymakers can do

These findings have practical implications for universities, research institutes, and funding agencies. Improving postdocs’ lives is not just about raising salaries, although financial support clearly matters. It also means building inclusive, well-resourced workplaces that protect mental health, offer genuine career guidance, and create real openings for advancement inside and outside academia. Structured mentoring, feedback that emphasizes growth, and programs that let postdocs build skills and see their progress can all strengthen self-efficacy. By investing in both external resources and internal confidence, institutions can foster a healthier, more motivated community of early-career researchers—supporting not only individual well-being but also the long-term vitality of scientific innovation.
