Interdependence, a mutual dependence between entities, is a key concept to understand interactions occurring in social and natural environments. We argue that understanding social and natural phenomena in terms of interdependence could predict children's pro-environmental behaviors (PEBs). The existing literature reveals a lack of studies promoting PEBs among children. We first reviewed the literature on interdependence to demonstrate why it is a theoretically viable construct to foster PEBs in children. Second, we identified a lack of instruments to measure children's preference for explanations in terms of interdependence. Thus, in study 1, we developed and administered a 9-item vignette-based scale combining pictures and everyday situations with various explanations, the Preference for Explanations in Terms of Interdependence scale—PETI to 351 Swiss pupils (10-12 years old). Exploratory factor analysis revealed a one-dimensional structure. Analyses showed satisfying nomological and predictive validity (on self-reported behaviors). Study 2 (N = 96) was conducted at recreational areas and aimed at extending the predictive validity of the PETI scale to actual behaviors. Contrary to our expectations, results revealed no direct effect of the PETI score, but a significant main effect of age, and a significant interaction effect between PETI and age showing that PETI was more positively associated to PEBs for older (10-13 years old) than for younger (6-9 years old) children. Reliability analyses suggested that the PETI scale is better suited for children aged 10 and over. We discuss the utility of the PETI scale in studying the relationship between children's understanding of interdependence and the endorsement of PEBs.

Abstract
Interdependence, a mutual dependence between entities, is a key concept to understand interactions occurring in social and natural environments. We argue that understanding social and natural phenomena in terms of interdependence could predict children's pro-environmental behaviors (PEBs). The existing literature reveals a lack of studies promoting PEBs among children. We first reviewed the literature on interdependence to demonstrate why it is a theoretically viable construct to foster PEBs in children. Second, we identified a lack of instruments to measure children's preference for explanations in terms of interdependence. Thus, in study 1, we developed and administered a 9-item vignette-based scale combining pictures and everyday situations with various explanations, the Preference for Explanations in Terms of Interdependence scale—PETI to 351 Swiss pupils (10-12 years old). Exploratory factor analysis revealed a one-dimensional structure. Analyses showed satisfying nomological and predictive validity (on self-reported behaviors). Study 2 (N = 96) was conducted at recreational areas and aimed at extending the predictive validity of the PETI scale to actual behaviors. Contrary to our expectations, results revealed no direct effect of the PETI score, but a significant main effect of age, and a significant interaction effect between PETI and age showing that PETI was more positively associated to PEBs for older (10-13 years old) than for younger (6-9 years old) children. Reliability analyses suggested that the PETI scale is better suited for children aged 10 and over. We discuss the utility of the PETI scale in studying the relationship between children's understanding of interdependence and the endorsement of PEBs.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
