Abstract Background School-based outdoor education (OE) is a teaching method aiming to promote pupils’ learning and wellbeing. OE with its action-oriented and cooperative learning approach can inspire teachers to develop their teaching and may also have a positive impact on their work wellbeing. According to self-determination theory, satisfaction or frustration of employees’ basic psychological needs - need for autonomy, competence and relatedness - are important facilitators or impediments of work wellbeing. We explored possible associations between OE use and teachers’ 1) satisfaction/frustration of basic needs at work and b) work engagement. Methods The study, part of the LärMiljö-study, used data collected in 2022 through electronic surveys among teachers in Swedish-language primary schools in Finland; N = 134 teachers from 44 schools. Main measures were the 24-item Basic Psychological Need Satisfaction and Need Frustration at Work Scale and 9-item Utrecht Work Engagement Scale. Data was analysed with Mann-Whitney U-tests and Spearman correlation. Results The vast majority was female, classroom teachers and had a master’s degree. Preliminary findings show that 69% practiced OE (sporadically or regularly) and 31% did not; both groups were similar in terms of teaching experience, age and gender. Teachers using OE had higher autonomy and competence need satisfaction, and lower relatedness need frustration than teachers not using OE (p < 0.05). There was no difference in overall work engagement (p = 0.07), but OE teachers had higher dedication to work (p < 0.05). Satisfaction of basic needs at work was positively, and frustration of needs negatively, associated with work engagement (p < 0.001). Conclusions Practicing OE appears to have positive associations with teachers’ dedication to work and satisfaction of need for autonomy and competence, and a negative association with relatedness frustration. More research is needed to confirm and examine the direction of these associations. Key messages • Outdoor education (OE) may besides pupils’ learning and wellbeing also promote teachers’ work wellbeing. Work wellbeing among teachers was studied within the framework of self-determination theory. • Practicing OE seems to be positively associated with teachers’ dedication to work, a sub-dimension of work engagement, and satisfaction of the basic needs for autonomy and competence at work.
