This reading offers to scientific researchers, an indispensable and non-existent guide to design qualitative interviews, specifying the structural, epistemological, methodological and ontological interdisciplinary paths to be used. Considering Freud (1912), Kvale (2011), Martinez (2002, 2006, 2011 and 2014), Moreno (1959) and Ruiz (1996 and 2012), among others, the Bintrafocused Matrix is innovated, whose use prevents the risk of dispersion of the researcher in the phase of information gathering, responding to "What" (goals) to establish, "Why" and "how" to search for information. It emerges from its use, academic discussion, consultation with multidisciplinary experts and calibration interviews, an instrument called "Charter Interview", inspired by psychoanalytic Psychodrama, the interviewees vividly act during the meeting, immersed in a sort of theatrical scenario, guided with techniques similar to those of Role Exchange, Mirror and Imaginary. It is concluded that the Bintrafocused Matrix prevents the risk of investigative dispersion and the Charter Interview significantly improves the projection of the imaginary in the interviewees.
