Psychometric Validation and Environmental Psychological Correlates of the Light Triad Traits

Abstract. The Light Triad Scale (LTS) measures the concept of the Light Triad, which was conceptualized as personality traits that reflect a person’s loving and beneficent orientation toward others, consisting of Faith in Humanity, Humanism, and Kantianism. As a novel construct, the Light Triad has yet to establish its structural validity in non-Western countries and needs to demonstrate its association with environmental psychology constructs. This study aims to: (1) examine the structural and criterion validity of the LTS in the Philippines and (2) determine the influence of the Light Triad on environmental concerns and green purchase intentions. Data were collected through an online survey completed by 447 Filipino adolescents. Comparing three models (i.e., one-factor, two-factor, and intercorrelated three-factor models), the present findings corroborated the original model which proposed an intercorrelated three-factor model of the LTS. The LTS demonstrated criterion validity by establishing correlations with relevant measures of environmental psychological constructs. Additionally, path analysis showed that Humanism and Kantianism predicted green purchase intentions via an increase in environmental concern. Measurement and conceptual strengths, future directions, and limitations are discussed.
