Abstract

The biophilia hypothesis states that human beings have an innate tendency to connect with nature. The current study aimed to examine the psychometric properties of the full and short versions of both the Environmental Identity Scale (EID) and the Nature Relatedness Scale (NR). Participants were 209 Singaporean undergraduate students (67.9% females) from a medium-sized university in Singapore. Exploratory factor analyses revealed a unidimensional structure for the Full EID and the Short EID. Acceptable internal consistency coefficients of .96 and .92 were found for the two instruments, respectively. Exploratory factor analyses revealed a three-factor structure for the Full NR: (a) NR-Self; (b) NR-Experience; and (c) NR-Perspective. However, two items were removed, and there are differences in the items that load on each factor. In addition, the NR-Perspective is unreliable, with an internal consistency coefficient of .62. Exploratory factor analyses revealed a unidimensional structure for the Short NR. An acceptable internal consistency coefficient of .82 was found. Taken together, the current study provided support for the use of the Full and Short EID and the Short NR as psychometrically valid instruments among Singapore undergraduate students.

Resumen

La hipótesis de la biofilia afirma que los seres humanos tienen una tendencia innata a conectar con la naturaleza. El presente estudio persigue examinar las propiedades psicométricas de las versiones completa y corta tanto de la Escala de Identidad Ambiental (Environmental Identity Scale, EID) como de la Escala de Relación con la Naturaleza (Nature Relatedness Scale, NR). Los participantes fueron 209 estudiantes de grado singapurenses (67.9% mujeres) de una universidad de tamaño medio en Singapur. Los análisis factoriales exploratorios encontraron una estructura unidimensional para las versiones completa y corta de la EID, también encontrando para estos dos instrumentos coeficientes de consistencia interna aceptables de .96 y .92, respectivamente. Para la NR completa, los análisis factoriales exploratorios encontraron una estructura de tres factores: (a) NR-Self; (b) NR-Experiencia; y (c) NR-Perspectiva. Sin embargo, se eliminaron dos ítems y se encontraron diferencias en los ítems que cargan en cada factor. Además, la NR-Perspectiva no es fiable, y tiene un coeficiente de consistencia interna de .62. Los análisis factoriales exploratorios mostraron una estructura unidimensional para la NR Corta. Se halló un coeficiente de consistencia interna aceptable, .82. En resumen, el presente estudio presta apoyo al uso de la EID Completa y Corta, y de la NR Corta, como instrumentos psicométricamente válidos para la población de estudiantes de grado en Singapur.
