Introduction:

The preparation of health professionals to obtain the scientific degree cannot be considered a collateral and accessory task, but one of the main activities for the solution of important health problems and the scientific-technological development of the sector.

Objectives:

Critically assess the main methodological weaknesses that arise in the elaboration of the theoretical framework of doctoral theses in Biomedical Sciences.

Methods:

A descriptive cross-sectional study was conducted where the unit of analysis were 25 doctoral theses approved during the five-year period 2010-2015.Theoretical level methods and empirical level methods were used as qualitative research techniques such as observation, interview and the analysis of documents. Once the information is obtained, the methodological triangulation of sources is carried out to arrive at integrative considerations.

Results:

The analysis of this structural component in the theses evaluated revealed a group of insufficiencies such as: non-observance of the historical chronology of the object / field, little consultation of normative documents, poor systematization of existing theories and their contributions, insufficient theoretical interpretation of the authors consulted to base their own judgments or a theory, poor exercise of scientific criticism in the analysis of the evidence and inadequacies in the writing of this section.

Conclusions:

It is evident that there are still inadequacies in the construction of the theoretical framework, therefore, the methodological suggestions made can serve as proposals to teachers who advise postgraduate academic training and researchers themselves in their scientific activity.
