This exploratory study evaluated a short-term (6–8 weeks) psychoeducation and support group for teachers focused on stress prevention and mindfulness (labeled SPAM group). A total of 4 groups were implemented in different schools, and evaluation was conducted with quantitative (pre- and post-measures of teacher vulnerability to stress, job satisfaction, and mindfulness) and qualitative (post-intervention interviews) elements using a quasi-experimental mixed methods design. Members reported higher mindfulness scores than participants in the comparison condition, which consisted of teachers in the same school who did not complete the group, and qualitative analyses were supportive of teachers’ satisfaction.
