Abstract

The present research integrates core aspects of social identity theory with the theory of planned behaviour to investigate factors influencing engagement in sustainable agricultural practices. Using a two-wave prospective design, two studies were conducted with samples of farmers (N = 609 and N = 259, respectively). At Time 1, a questionnaire survey assessed theory of planned behaviour variables in relation to engaging in riparian zone management (a sustainable agricultural practice). In addition, intergroup perceptions (i.e. relations between rural and urban groups), group norms and group identification were assessed. At Time 2, self-reported behaviour was measured. There was support for the integrated model across both studies. As predicted, past behaviour, attitudes and perceived behavioural control were significant predictors of intentions, and intentions significantly predicted self-reported behaviour. Group norms and intergroup perceptions were also significant predictors of intentions providing support for the inclusion of social identity concepts in the theory of planned behaviour. More supportive group norms were associated with higher intentions, especially for high-group identifiers. In contrast, more negative intergroup perceptions were associated with lower intentions and, unexpectedly, this effect only emerged for low-group identifiers. This suggests that in the context of decisions to engage in riparian zone management, an important sustainable agricultural practice, high identifiers are influenced predominantly by in-group rather than out-group considerations, whereas low identifiers may attend to cues from both the in-group and the out-group when making their decisions.

摘要

本研究将社会认同理论的核心方面与计划行为理论相结合,以调查影响参与可持续农业实践的因素。采用两波前瞻性设计,对农民样本进行了两项研究(样本量分别为N = 609和N = 259)。在时间1,通过问卷调查评估了与参与河岸带管理(一种可持续农业实践)相关的计划行为理论变量。此外,还评估了群体间认知(即农村和城市群体之间的关系)、群体规范和群体认同。在时间2,测量了自我报告的行为。两项研究均支持整合模型。正如预测的那样,过去的行为、态度和感知行为控制是意图的显著预测因素,而意图又显著预测了自我报告的行为。群体规范和群体间认知也是意图的显著预测因素,这为在计划行为理论中纳入社会认同概念提供了支持。更支持性的群体规范与更高的意图相关,尤其是对于高群体认同者。相比之下,更消极的群体间认知与更低的意图相关,而且出乎意料的是,这种效应仅在低群体认同者中出现。这表明,在参与河岸带管理(一项重要的可持续农业实践)的决策背景下,高认同者主要受内群体而非外群体因素的影响,而低认同者在做决策时可能会关注来自内群体和外群体的线索。
