Psychometric properties of the Inventory of Interpersonal Problems-64 in Colombia

Psychometric study of the Inventory of Interpersonal Problems-64 (IIP-64) in an online convenience sample of 701 participants in Colombia. Internal consistency was estimated with Cronbach's Alpha and McDonald's Omega, yielding acceptable to good results. Construct validity was examined through principal component analysis (PCA) and its representation on a Cartesian plane; both showed two main dimensions allowing derivation of the eight theoretical scales of the interpersonal circumplex octagonal model. Descriptive values and quartiles were calculated for population reference. With minor caveats, the IIP-64 is valid and reliable in Colombia.
