S-Index Interpretation
The S-Index (Sharing Index) is a comprehensive metric that represents the cumulative impact of all your datasets. It is calculated as the sum of Dataset Index scores across all your claimed datasets.
What it means:
- A higher S-index indicates greater overall impact of your datasets relative to typical datasets in their fields of research
- The S-Index grows as you add more datasets or as existing datasets gain more citations and mentions
- It provides a single number to track your research data impact over time
Current S-Index: 4.4 (sum of 6 datasets Dataset Index scores)

The Teachers’ Occupational Wellbeing Study examines Finnish teachers’ occupational wellbeing, along with its predictors and outcomes, using a comprehensive survey questionnaire. Attention is also given to demographic aspects, such as regional differences and variation across educational levels and institutions. The aim is to use the findings to inform interventions, teacher training, and policy development.The study began in spring 2020, at the onset of the COVID-19 pandemic and was started by Professor Katariina Salmela-Aro (1961-2025). Since then, data have been collected biannually every spring and autumn. In addition, the collection of longitudinal data began in spring 2024. This design enables the examination of both general trends (cross-sectional data) and individual-level changes over time (longitudinal study).The survey data have been gathered in close collaboration with the Trade Union of Education in Finland (OAJ), consisting of responses from its members. The participants include teachers from across Finland and all educational levels.The study is currently part of and funded by the EDUCA Flagship. More information about the study and its main results can be found on the EDUCA Flagship website and in the supporting materials provided on this page. The project is currently led by University Lecturer Dr. Lauri Hietajärvi ([email protected]) from University of Helsinki, Finland, and managed by Dr. Olli-Pekka Heinimäki ([email protected]) from the same university. ****Selected sections of datasets from 2020 to 2024 have been made openly available for anyone to use. Please read the relevant documentation carefully before working with the data. Should you have any questions, please contact the project management.The attached documents includes:Teacher occupational wellbeing study data collection report – openly distributed version: Details about the project and data collection.Time Series 2020–2025: Key wellbeing trends across the full dataset (each time point).Representativeness of the Data: Estimates of representativity at each measurement point.Teacher_occupational_wellbeing_measures_overall: Summary of all measures included in the survey across timepoints.README: Information about the open-access datasets and how they were generated from the original data.2020_Spring.zip – 2024_Spring.zip: Nine open-access datasets collected at different time points (each provided in both .sav and .csv formats).Scale documentation 2020–2024 open: Scale documents for each of the published nine datasets.

The Principal barometer is an ongoing follow-up study of principals, deputy principals, vice-principals, and school leaders of primary education or upper secondary education in Finland. The principal barometer is an extensive longitudinal study aimed at investigating the occupational well-being of Finnish principals. The research is carried out in co-operation between researchers from the University of Helsinki and Suomen Rehtorit ry (Association of Finnish school principals). Our primary goal is to investigate and follow the well-being of Finnish principals and compare with international data as well as other industries and professions. This project is adjacent to the international Educator Health and Wellbeing study, led by Professor Philip Riley from Australia, and involves collaboration with Australian Catholic University’s Institute for Positive Psychology and Education.We utilise a comprehensive questionnaire to examine the principals' work situation, well-being, resources, and management practices. Additionally, we collect physiological data, such as HRV (heart rate variability) using the Firstbeat device, which tracks rest time, working time, and exercise. Our focus areas include recovery, job crafting, servant leadership, engagement, and burnout.More information about the Principal Barometer here.Note: the survey is distributed in Finnish and Swedish, some of the material are translated to english. This Zenodo record will be updated periodically. Inquiries for more information, possible collaboration and use of the dataset are welcomed.Files:Raportti Rehtoribarometri 2024.pdf - contains a report on the results of the 2024 surveyThe Finnish Principal Barometer (2019-2024).pdf - contains a short description of the project and datasetrehtoribarometri_measures_longitudinal_20250508.xlsx - contains an overview of the measures included across the waves

NOTE: Version 2 provides the updated numbers for this data set.The primary aim of this research project is to study teachers’ work-related well-being in Finland, and its relationship with various work-related demands and resources. Study of teachers' work-related well-being in Finland has been conducted from 2020 onwards. An online questionnaire distributed biannually enables a comprehensive examination of teachers’ well-being across different regional and educational contexts. Beginning 2024, the study expands to include longitudinal research.Since 2020, an online questionnaire has been distributed biannually to OAJ (the Trade Union of Education in Finland) members towards the end of each spring and autumn semester. The respondents include teachers from all across Finland, representing a wide range of educational levels. This broad data collection enables a comprehensive examination of teachers’ well-being across different regional and educational contexts.Initially, responses were collected anonymously, enabling the tracking of well-being trends over time. Beginning in Spring 2024, the study expanded to include the collection of contact information from consenting participants, setting the stage for future longitudinal research.Data was collected between 2020–2024 as follows:Spring 2020: 1 182 participants.Autumn 2020: 1 502 participantsSpring 2021: 1 336 participants.Autumn 2021: 1 046 participants.Spring 2022: 476 participants.Autumn 2022: 687 participantsSpring 2023: 1 628 participants.Autumn 2023: 1 396 participants.Spring 2024: 1 182 participants.Information about the data set can be found at: https://www.helsinki.fi/en/researchgroups/motivation-learning-and-well-being-in-digital-era/study-of-teachers-work-related-well-being This research is conducted by the University of Helsinki in collaboration with the Trade Union of Education in Finland (OAJ).The study is led by Academy Professor Katariina Salmela-Aro ([email protected]). For inquiries, please contact University Lecturer Lauri Hietajärvi ([email protected]) or Postdoctoral Researcher Olli-Pekka Heinimäki ([email protected]).This research has been funded by the Strategic Research Council as part of the EduRESCUE research project and by the Academy of Finland for the EDUCA research flagship.
