ELYSEU JUNIOR, Sebastião  and  YOSHIDA, Elisa Medici Pizão. EPP - Ownership patterns scale: construction, validity and reliability. Aval. psicol. [online]. 2008, vol.7, n.2, pp. 159-170. ISSN 1677-0471.

The study presents an initial evaluation of the psychometrics properties of the Escala de Padrões de Posse-EPP (Ownership Patterns Scale), a self-report instrument, designed to measure ownership. Ownership is conceived as behavior patterns of conquering and/or maintenance of an ownership figure: people, pets, things, places, and goods in general. Its function is the regulation of provision of goods to the usufruct of the individual and his or her offspring , as well as, to preserve the species. Participants were 296 undergraduate (140 male and 156 female). Items were developed to assess four patterns of ownership - secure, anxious, jealous and reactive ownership -, and two patterns of "non-ownership" - detachment and envious. Results pointed to acceptable temporal stability for some patterns and satisfactory internal consistence. A factorial structure study suggested that ownership is better represented by the following dimensions: Security of Ownership of People and Security of Ownership of Things.
