4.4. Limitations
While this study offers valuable insights into the relationship between positive education practices and teacher well-being, several limitations should be acknowledged. This study employed a convenience sampling method, which may limit the generalisability of the findings. Participants self-selected into the study, potentially introducing selection bias. Furthermore, the sample was predominantly female (84.6%) and urban-based (77.1%), which reflects the demographic makeup of the teaching workforce in Greece but restricts broader applicability—particularly to male educators and those in rural or underserved regions. Future studies should aim for stratified or randomised sampling to ensure more balanced demographic representation.
This study’s cross-sectional design provides a snapshot of associations between variables but does not allow for causal inferences. Longitudinal or experimental designs would be more appropriate to examine how implementing positive education practices influences changes in well-being, life satisfaction, and self-efficacy over time. Moreover, integrating qualitative methods, such as interviews or focus groups, could provide richer insights into teachers’ subjective experiences and the contextual nuances of implementation.
Furthermore, the findings are situated within Greece’s specific socio-cultural and educational context. While the instruments used were validated in Greek samples, caution should be exercised in generalising the results to teachers in other cultural or educational systems without further cross-cultural validation. All data were collected through self-report questionnaires, which can be influenced by social desirability bias and subjective interpretation. While validated tools were employed (e.g., PEPS, the PERMA Profiler, the SWLS, the TSES), supplementing self-report data with observational or qualitative methods in future research could provide a more nuanced understanding of implementation fidelity and contextual factors.
Another important limitation of this study is the potential influence of unmeasured contextual variables that may act as confounders. While demographic characteristics such as age, gender, educational level, and teaching experience were statistically controlled, other factors—such as school leadership practices, teacher workload, organisational climate, and student demographics—were not directly assessed. These variables could plausibly affect the implementation of positive education practices and teacher perceptions of well-being. For instance, supportive leadership and manageable workloads may facilitate the adoption of positive practices while also independently enhancing staff morale and engagement. Future research would benefit from incorporating multilevel modelling or mixed-methods designs to account for these school-level and contextual influences. Doing so would allow for a more nuanced understanding of the conditions under which positive education practices are most effectively implemented and experienced.
4.5. Implications, Challenges, and Future Directions
This study offers important educational policy, practice, and research implications, particularly in light of persistent structural and institutional challenges. Although the value of positive education is increasingly acknowledged, its implementation remains hindered by several barriers. These include limited teacher training, resistance to pedagogical innovation, mounting performance pressures, and a general lack of systemic and institutional support (
Brunzell et al., 2018;
Waters & Loton, 2019). Addressing these issues requires more than isolated efforts; instead, coordinated and sustained reform is necessary across multiple levels of the education system.
A critical step toward such reform involves systematically embedding well-being science into pre-service teacher education and ongoing professional development. Ensuring teachers are adequately prepared to implement positive education practices demands consistent and targeted investment. This can be achieved by allocating funding specifically for long-term training programmes in positive psychology, including certified courses, in-school workshops, and collaborative initiatives with higher education institutions. Equitable access to these opportunities is especially important for schools in under-resourced or high-need contexts, where structural challenges are most acute.
In addition to investment in professional learning, systemic change must include integrating well-being practices into national and regional educational frameworks. Education authorities can legitimise positive education as a core pedagogical priority rather than a peripheral initiative by formally embedding these principles into teaching standards, curriculum guidelines, and teacher evaluation systems. Such integration elevates the status of well-being within education systems and promotes greater coherence and consistency in implementation.
The role of school leadership is also pivotal in this process. Leaders should be supported and incentivised to prioritise teacher and student well-being through leadership development in social and emotional learning, performance frameworks that include well-being indicators, and the institutional recognition of well-being initiatives. Furthermore, adopting whole-school implementation frameworks, such as PERMAH, SEARCH, or the Positive Educational Practices Framework, offers a structured and scalable approach for aligning well-being principles with school culture, teaching practices, and relational dynamics.
Equally important is recognising that schools operating in high-stress or low-resource environments require flexible, context-sensitive implementation models. Blended training options, increased access to psychosocial support services, and culturally relevant adaptations are essential strategies for addressing disparities in opportunity and impact. Beyond these structural adjustments, school leadership must also model psychological safety, empathy, and trust. Cultivating a culture that actively supports the well-being of both staff and students is central to ensuring sustainable and meaningful change. Integrating social and emotional learning (SEL) within broader school improvement agendas can further reinforce a holistic, human-centred approach to education.
In addition to these practical and policy-oriented recommendations, this study highlights several key directions for future research. Longitudinal designs are particularly important for capturing the development of teacher well-being, job satisfaction, and self-efficacy over time—especially before, during, and after implementing positive education practices. Such research would offer valuable insights into long-term outcomes, including the prevention of burnout, the enhancement of teacher retention, and the sustainability of instructional effectiveness.
Moreover, employing mixed-methods approaches that combine quantitative analysis with qualitative inquiry would enable a more nuanced and contextually grounded understanding of how teachers experience and implement positive education. Exploring factors such as individual motivation, sources of resistance, and coping strategies during implementation would contribute to developing more adaptable and effective interventions.
Comparative research across cultural and educational systems also holds promise for expanding the applicability of well-being pedagogy. Such studies could illuminate how positive education is understood and enacted in different contexts, thereby identifying culturally appropriate practices and informing the customisation of interventions to local needs. Additionally, future studies should examine the relative efficacy of specific interventions—such as mindfulness practices, gratitude-based activities, or values-driven approaches—in enhancing teacher resilience and engagement. Identifying the most effective and scalable strategies will be crucial for evidence-based programme planning and policy development.
Finally, there is an urgent need to focus research efforts on how positive education can be effectively tailored and sustained in under-resourced and high-need settings. In these environments, teacher stress is often greatest and institutional support most limited. Developing flexible, equity-focused models of positive education that are feasible and impactful in such contexts will be essential for bridging the well-being gap and promoting more inclusive and sustainable educational reform.
