Providing a Causal Model of the Perception Relationships of of Social Support and Environmental Responsibility Based on the Role of Psychological Capital among Secondary School Students

The purpose of this study was to provide a causal model of the relationships between social support perception and environmental responsibility with regard to the mediating role of psychological capital among secondary school students in Larestan by path analysis. For this purpose, 341 secondary school students (181 girls and 160 boys) were selected by ratio stratified sampling method and then, answered to a self-report questionnaire consisting of social support (Wax, 1986), psychological capital (Luthans, 2007) and the environmental responsibility (Hui Saos, 2005) subscales. To confirm the reliability of subscales, Cronbach's alpha coefficient was used. Overall, the results of the research showed that social support (family support, teachers, and peers) through the mediation of psychological capital (resilience, hope, self-efficacy, and optimism) has an indirect and positive effect on environmental responsibility. Among the components of psychological capital, optimism and hope have the greatest direct impact on environmental responsibility. Among the dimensions of social support, family support has the most indirect effect on environmental accountability.
