STOPPIELLO, Luis Alberto. Early Triadic Interaction Scale (ETIS): Issues concerning its reliability and validity. Subj. procesos cogn. [online]. 2011, vol.15, n.2, pp.111-132. ISSN 1852-7310.

When the author started working with films regarding a triad family, he had to deal with two problems: the bias of the researcher and the criteria for sample fragmentation. The paper presents the two alternative solutions devised: concerning the first issue, the creation of a score instrument for early triadic interaction sequences and concerning the second issue, the theoretical justification for the beginning and end cuts of each filming session, according to Greimas semiotics. Finally, the author considers the scale created from the standpoint of reliability and validity of the instrument.
