The interplay among environmental attitudes, pro-environmental behavior, social identity, and pro-environmental institutional climate. A longitudinal study

By using a panel design in a sample of 298 undergraduate/master students at an Italian public university, the present study aimed to test longitudinally the interplay among environmental attitudes, pro-environmental behavior, social identity, and pro-environmental institutional climate. The relationships were tested with cross-lagged analysis based on two waves over a 2-month period. The cross-lagged panel analysis revealed positive cross-lagged effects of social identity on environmental attitudes and pro-environmental institutional climate perceptions on social identity. Environmental attitudes and social identity at Time 1 did not predict Time 2 pro-environmental behavior. Pro-environmental behavior at Time 1 did not predict Time 2 environmental attitudes. Pro-environmental institutional climate perceptions at Time 1 did not predict Time 2 pro-environmental behavior. Finally, social identity at Time 1 did not predict Time 2 pro-environmental institutional climate perceptions.
