Aim/Purpose. Doctoral education still suffers from two severe overlapping problems: high dropout rates and low emotional wellbeing experienced by many doctoral candidates (e.g., depression or anxiety symptoms). Yet, there are few interventional approaches specifically designed to address them in the doctoral student population.Background. Among structural, psychosocial and demographic factors influencing these problems, the self-perception of progress has emerged recently as a crucial motivational factor in doctoral persistence. This paper explores an intervention approach (in the form of workshops) focusing on doctoral progress. Methodology. This paper reports on an iterative design-based research study of workshop interventions to foster such perception of progress in doctoral students’ everyday practice. We gathered mixed data over four iterations, with a total of N=82 doctoral students from multiple disciplines in Spain and Estonia.Contribution. An approach to preventive interventions that combines research-backed education about mental health and productivity, peer sharing and discussion of experiences and indicators of progress, as well as self-tracking, analysis and reflection upon everyday evidence of their own progress. The paper provides initial evidence of the effectiveness of the proposed interventions, across two institutions in two different countries. Further, our data confirms emergent research on the relationships among progress, emotional wellbeing and dropout ideation in two new contexts. Finally, the paper also distils design knowledge about doctoral interventions that focus on progress, relevant for doctoral trainers, institutions and researchers.Findings. Our quantitative and qualitative results confirm previous findings on the relationships among progress, burnout and dropout ideation. Our iterative evaluation of the workshops also revealed a large positive effect in students’ positive psychological capital after the workshops (Cohen’s d=0.83). Our quantitative and qualitative analyses also started teasing out individual factors in the variance of these benefits.Recommendations for Practitioners. Intervention design guidelines for doctoral trainers include: focusing on actionable productivity and mental health practices, the use of activities targeting perception biases and taboos, or the use of active practices and real (anonymous) data from the participants to make progress visible and encourage reflection.Recommendations for Researchers. The construct of progress, its components and its relationships with both emotional wellbeing and doctoral dropout, need to be more deeply studied, using multiple methods of data collection, especially from more frequent, ecologically valid data sources (e.g., diaries).Impact on Society. The proposed interventions (and focusing on doctoral progress more generally) hold promise to address the current emotional wellbeing and dropout challenges facing hundreds of thousands of doctoral students worldwide, ultimately helping increase the research and innovation potential of society as a whole.Future Research. More rigorous evaluative studies of the proposed approach need to be conducted, with larger samples and in other countries/contexts. Aside from the proposed one-shot training events, complementary longitudinal interventions focusing on supporting everyday progress and reflection throughout the doctoral process should be trialed.
