The present study aimed to analyze the Inventory of Interpersonal Problems-64 (IIP-64) reliability and validity in an incidental online community sample of 701 participants living in Colombia. The internal consistency of the scales was estimated by two methods, Cronbach’s alpha and McDonald’s Omega, with acceptable to good results. Evidence of construct validity was analyzed using principal component analysis (PCA) and its plotting in a Cartesian plane. The PCA and the graphical analysis results indicate that the instrument has two main dimensions that allow the derivation of the eight theoretical scales of the octagonal circumplex model of interpersonal behavior. The descriptive values of the scales and quartiles were also estimated for their reference to the Colombian population. It is concluded that, with some minor considerations, the instrument is valid and reliable in the Colombian population.
