Published in BMC Medical Education, the following study aims to (1) adapt a Spanish version of the Burnout Clinical Subtype Questionnaire-12 for use with students, (2) test its factorial validity, internal consistency, convergent and discriminant validity, and (3) assess potential socio-demographic and occupational risk factors associated with the development of the subtypes. The three established subtypes in the BCSQ-12 are the “frenetic” (related to “overload”), “under-challenged” (related to “lack of development”), and “worn-out” (related to “neglect”). The results support the definition of burnout and affirms that BCSQ-12-SS can be used for the recognition of clinical profiles and for the suggestion of intervention strategies specific to the characteristics of each particular case.
