The present study was meant to investigate longitudinal change in pro-environmental behaviour from the early teenage years to early adulthood as it relates to changes in nature connectedness and the endorsement of pro-environmental norms. A cross-sequential study design was used in which two cohorts of Canadian adolescents (12- to 14-year-olds, = 220, 110 females, and 18- to 20-year-olds, = 390, 305 females) were followed up longitudinally over four years and three waves of data collection. All measures were based on Rasch scales. Latent growth models demonstrated non-linear change in both cohorts. Pro-environmental behaviour, connectedness with nature and norm endorsement significantly increased in the first two years of the longitudinal study, while this increase levelled off thereafter. Cross-lagged panel analyses demonstrated that nature connectedness and endorsement of pro-environmental norms reciprocally predicted pro-environmental behaviour in both cohorts, with one dominant path from pro-environmental behaviour to norm endorsement. As adolescents and young adults continue to engage in pro-environmental behaviour, they increasingly tend to endorse pro-environmental norms. Connectedness with nature and norm endorsement, by contrast, did not evidence any cross-lagged relationship. Overall, the study provides valuable insights into how the disposition to engage in pro-environmental behaviour forms in youth.

青年的环保行为、与自然的联系以及对环保规范的认可：纵向关系

本研究旨在调查从青少年早期到成年早期亲环境行为的纵向变化，因为它与自然联系的变化和对亲环境规范的认可有关。采用交叉序贯研究设计，对两组加拿大青少年（12 至 14 岁，= 220 名女性，110 名女性，以及 18 至 20 岁，= 390 名女性，305 名女性）进行了随访纵向历时四年、三波数据收集。所有测量均基于拉希量表。潜在增长模型显示了两个队列中的非线性变化。在纵向研究的前两年，亲环境行为、与自然的联系和规范认可显着增加，但此后这种增加趋于平稳。交叉滞后面板分析表明，自然关联性和对亲环境规范的认可可以相互预测两个群体的亲环境行为，并且从亲环境行为到规范认可有一个主要路径。随着青少年和年轻人继续参与有利于环境的行为，他们越来越倾向于认可有利于环境的规范。相比之下，与自然的联系和规范的认可并没有证明任何交叉滞后的关系。总体而言，这项研究为了解青年人如何形成环保行为的倾向提供了宝贵的见解。
