The study of pro-environmental behavior has been dominated by self-report scales and field observations. Although both approaches have their merits, they also suffer from critical limitations that obstruct progress towards a better understanding of pro-environmental behavior. The Pro-Environmental Behavior Task (PEBT) was developed to address these limitations by facilitating the study of actual pro-environmental behavior under controlled laboratory conditions. In the present research, we examined whether the PEBT can also provide a valid and reliable indicator of people's propensity to show pro-environmental behavior. In support of the task's test-retest reliability, we found PEBT choice behavior to be strongly correlated across a period of approximately one month (r = 0.81). In addition, PEBT performance was significantly correlated to both objective observations and subjective reports of other pro-environmental behaviors. Our results further suggest participants' PEBT choices to be most closely related to individual differences in transportation behavior. These findings indicate that the PEBT might prove useful not only as a procedure for the experimental study of pro-environmental behavior, but also for the performance-based assessment of a person's propensity to engage in pro-environmental behavior.

自我报告量表和实地观察已成为对环境行为研究的主导。尽管这两种方法都有其优点，但它们也受到严重的限制，阻碍了对更好地了解环保行为的进展。开发环境友好行为任务（PEBT）是为了通过在受控实验室条件下促进对实际环境行为的研究来解决这些限制。在本研究中，我们研究了PEBT是否还可以提供有效和可靠的指标来表明人们表现出亲环境行为的倾向。为了支持任务的重测可靠性，我们发现PEBT选择行为在大约一个月的时间段内与相关性很强（r = 0.81）。此外，PEBT的表现与其他客观的环保行为的客观观察结果和主观报告显着相关。我们的结果进一步表明，参与者的PEBT选择与运输行为的个体差异最密切相关。这些发现表明，PEBT不仅可以作为对环保行为进行实验研究的程序，而且可以用于基于绩效的人对环保行为倾向的评估。
