Development and Validation of the Marburg Self-Regulation Questionnaire for Teachers (MSR-T). Trends in Higher Education. 2023; 2(3):434-461. https://doi.org/10.3390/higheredu2030026 As part of the studies, items for a questionnaire measuring teachers' self-regulation competencies in four professionally relevant contexts were constructed and subjected to item analyses in Study 1, resulting in a reduction from 79 to 55 items. In addition, associations between self-regulation and job and health satisfaction (individual items) were examined in several regression analyses. In the second study, item reduction was again carried out on the basis of item analyses and a CFA, and the final version of the questionnaire (27 items) was correlated with convergent and divergent questionnaires to investigate validity.
