Desarrollo y validación psicométrica de la Escala de Privacidad en la Vivienda

ResumenEl propósito de este estudio fue generar un instrumento que permita medir la privacidad en las viviendas urbanas de México de manera confiable y válida. Para lo cual se construyó una escala conformada por 20 reactivos con cinco opciones de respuesta; para realizar su validación psicométrica se aplicó a 200 habitantes de la Ciudad de México, de entre los 14 y 75 años de edad, 110 mujeres y 90 hombres con diferentes ocupaciones y grados de escolaridad. Se llevaron a cabo análisis para conocer el poder discriminativo de los reactivos; la confiabilidad y la estructura factorial válida para la población de la Ciudad de México. La escala final estuvo constituida por 11 reactivos, organizados en tres factores Control de Acceso a la Información, Control de Acceso a la Persona e Intimidad.

The main objective of this research was to generate a reliable and valid scale that assessed dwelling privacy in Mexico City’s population. A scale was developed specifically for this purpose. The scale included 20 items with five options for answers (Never, few times, sometimes, frequently and always). The scale was applied to a sample of 200 Mexico City’s inhabitants in order to obtain its psychometrical validation. The distribution of the participants was as follow: age between 14 to 75; 110 women and 90 men: diverse occupations and school levels. A proper analysis took place in order to learn about the items discriminative power, reliability and valid factorial structure. The final scale was conformed by 11 items organized by three factors as follow: 1) Information Access Control, 2) Person Access Control and 3) Intimacy it explains 68% of variance and has a reliability of Cronbach Alpha =0.89. Afterwards a Confirmatory Factor Analysis was conducted to verify if the structure obtained from the Principal Component Analysis was correct, and a good fit was achieved (df=39, x2= 48.07, p = .151; CFI= .987; RMSEA= .032).
