Introduction: The World Health Organization (WHO) has defined the word “health” not only as the absence of an illness, but as a perspective that goes beyond the physical or biological wellfare of a person, involving a mental and social prosperity of an individual. Because of all these aspects, the health specialist or the so called Internal User has the need to adapt himself/herself to a new way of intervention in the Familiar Health Center, that it used to be called “health center” or “doctor’s office”. Objective: Determine the perception that the intern user has about the biomedical transition to the biopsychosocial one. Materials and methods: using quantitative methodology with a phenomenological approach. The instrument used was an interview that was applied to 23 users, specialists, related to the Family Health Center Pinares, located in Chiguayante, in February 2009. Results and discussion: The information does not demonstrate the rejection to the new Model of Familiar Health. Nevertheless, you can observe deficient or fragmented knowledge that was brought together with not so many resources; making difficult the implementation of the biopsychosocial model
