The ABC connectedness to nature scale: development and validation of a scale with an approach to affective, behavioural, and cognitive aspects

Connectedness to nature influences the well-being and health of individuals, communities, and the planet. Although many validated scales exist, none includes the three fundamental aspects of any attitude: the affective, behavioural, and cognitive components. The study’s main objective was to develop and validate an integral tool, the ABC Connectedness to Nature Scale (ABC-CNS), which would enable the measurement of the affective, behavioural, and cognitive aspects of this construct. The questionnaire was administered to 1,375 students (878 Ecuadorian and 497 Spanish). Exploratory factor analysis retained the three expected factors. Confirmatory factor analyses confirmed a robust adjustment for the tridimensional structure, but cross-cultural invariance was not attained: Although the ABC-CNS is valid for both Ecuador and Spain, the scores cannot be compared in both cultural contexts analysed. The pattern of relations with other psychological variables (proenvironmental values, appreciation and preservation of nature, and individual and classmates’ proenvironmental behaviours) provided evidence of the structure and construct validity. The ABC-CNS scale is an integral, reliable, and short tool to measure connectedness to nature through the proposed dimensions. The tool is suitable for environmental professionals and researchers to assess individuals’ connectedness to nature, a psychological variable that may affect a person’s mental health and proenvironmental behaviour.
