Study limitations
SECONDARY
Because this study is a secondary outcome analysis and was not initially used to detect differences in symptoms of burnout, a power calculation was not performed. The response rate on the self-reported questionnaire was relatively high (75%). However, there remains a risk of non-response bias. Another area for improvement is that the SMBQ might not precisely reveal the clinical picture of the different diagnoses included in CMDs, which may have impacted the results. Being involved in a research study might also have affected participants’ motivation to engage in TAU.
