Plastic waste management is one of the most challenging problems of our time. Until now, only 9% of the produced plastics has been recycled. In order to increase recycling, a behavior change towards sorting of plastic waste is needed. Therefore, the main aim of the study is to gain insight in the individual and situational determinants associated with plastic waste sorting behavior. The Integrated Framework for Encouraging Pro-environmental Behaviour will be used as the theoretical framework. This framework assumes that individual egoistic and hedonic values are negatively related to pro-environmental behaviour, whereas individual biospheric and altruistic values are positively related to pro-environmental behaviour. Situational cues can activate these values, resulting in (non) pro-environmental behaviour. Taking the Integrated Framework for Encouraging Pro-environmental Behaviour into account, this study will test the hypothesized associations between individual and situational determinants and plastic waste sorting behavior, using an ecological momentary assessment approach (Experience Sampling Method, ESM). A signal-contingent scheme with semi-random intervals will be used for the ESM questionnaire. Over a period of seven consecutive days, an ESM-based smartphone app will prompt participants ten times a day to fill in a short questionnaire containing questions about situational determinants and plastic waste sorting behaviour. Participants will also complete an online questionnaire before and after the study measuring the individual determinants and plastic waste sorting behaviour. ESM has many benefits over traditional surveys, such as improved ecological validity and the possibility to explore temporal relationships. The disadvantages of ESM are mainly related to the burden for the participants and the possibility of reactivity effects. The results will provide insight into the relationship between situational cues, individual values and plastic waste behaviour. The practical implications of the findings of this study can be of interest for policy makers in order to reach plastic waste reduction targets. Furthermore, the situational cues that activate values, which increase or decrease plastic waste sorting, can be targeted in interventions. The results of this study can also be relevant for further research studying and stimulating pro-environmental behaviour in general.

塑料垃圾分类的个体和情境决定因素:经验抽样方法研究协议

塑料废物管理是我们这个时代最具挑战性的问题之一。到目前为止,只有 9% 的生产塑料得到了回收利用。为了增加回收利用,需要改变对塑料废物分类的行为。因此,该研究的主要目的是深入了解与塑料垃圾分类行为相关的个体和情境决定因素。鼓励亲环境行为的综合框架将用作理论框架。该框架假设个人利己主义和享乐价值观与亲环境行为负相关,而个人生物圈和利他主义价值观与亲环境行为正相关。情境线索可以激活这些价值观,导致(非)亲环境行为。考虑到鼓励亲环境行为的综合框架,本研究将使用生态瞬时评估方法(经验抽样方法,ESM)测试个人和情境决定因素与塑料垃圾分类行为之间的假设关联。ESM 问卷将使用具有半随机间隔的信号随机方案。在连续 7 天的时间里,基于 ESM 的智能手机应用程序每天会提示参与者十次填写一份简短的问卷,其中包含有关情境决定因素和塑料垃圾分类行为的问题。参与者还将在研究之前和之后完成一份在线问卷,以测量个体决定因素和塑料垃圾分类行为。与传统调查相比,ESM 有很多好处,例如提高生态有效性和探索时间关系的可能性。ESM 的缺点主要与参与者的负担和反应性效应的可能性有关。结果将深入了解情境线索、个人价值观和塑料垃圾行为之间的关系。这项研究结果的实际意义可能会让政策制定者感兴趣,以实现减少塑料废物的目标。此外,可以在干预中针对激活价值的情境线索,从而增加或减少塑料垃圾分类。这项研究的结果也可能与进一步研究和刺激一般的亲环境行为有关。ESM 的缺点主要与参与者的负担和反应性效应的可能性有关。结果将深入了解情境线索、个人价值观和塑料垃圾行为之间的关系。这项研究结果的实际意义可能会让政策制定者感兴趣,以实现减少塑料废物的目标。此外,可以在干预中针对激活价值的情境线索,从而增加或减少塑料垃圾分类。这项研究的结果也可能与进一步研究和刺激一般的亲环境行为有关。ESM 的缺点主要与参与者的负担和反应性效应的可能性有关。结果将深入了解情境线索、个人价值观和塑料垃圾行为之间的关系。这项研究结果的实际意义可能会让政策制定者感兴趣,以实现减少塑料废物的目标。此外,可以在干预中针对激活价值的情境线索,从而增加或减少塑料垃圾分类。这项研究的结果也可能与进一步研究和刺激一般的亲环境行为有关。个人价值观和塑料垃圾行为。这项研究结果的实际意义可能会让政策制定者感兴趣,以实现减少塑料废物的目标。此外,可以在干预中针对激活价值的情境线索,从而增加或减少塑料垃圾分类。这项研究的结果也可能与进一步研究和刺激一般的亲环境行为有关。个人价值观和塑料垃圾行为。这项研究结果的实际意义可能会让政策制定者感兴趣,以实现减少塑料废物的目标。此外,可以在干预中针对激活价值的情境线索,从而增加或减少塑料垃圾分类。这项研究的结果也可能与进一步研究和刺激一般的亲环境行为有关。
