RT Journal Article T1 Otherness measuring scale: design and validation for social sciences A1 Mateus De Oro, Cirit A1 Jabba Molinares, Daladier A1 Erazo Coronado, Ana María A1 Aguaded, José Ignacio A1 Campis Carrillo, Rodrigo Mario A1 Parody, Alexander AB This paper is the result of a scale validation process, applicable to social science research, which allows the constructsof otherness and coexistence and their relationship to be trasnformed into measurable, systematized variables. Inturn, this scale is the product of a research project whose main objectives were (i) to demonstrate the relationshipbetween coexistence as an independent variable and otherness as a dependent variable, and (ii) to create and statisticallyvalidate a scale to measure both variables, so to use it in applied research. The sample consisted of 600participants. Three instruments were used: two semantic differentials and a 33-item questionnaire. The applicationwas carried out virtually due to the SARS-CoV-2 virus. The method includes a mixed type of work, i.e., qualitative,and quantitative procedures. The results showed two factors, the other as strange or foreign and the other as equal.The final scale consisted of 10 items, with a Cronbach’s alpha of 0.86 and variance explaining 58% of the otherness.
