The article addresses an imporant and under-explored issue of eradicating single-use cups using theoretical framework of behaviour change. As there is not much literature on this particular behaviour, and none - to my knowledge - of the application of the Behaviour Change Wheel theory to it, it has a potential to contribute to the field significantly. At this stage, this is a protocol of a mixed-methods study.
It would be beneficial to expand the literature review to elaborate more on two areas:
a) Include the research on previous efforts made to increase the use of reusable cups, for instance, the two behaviour change interventions, published recently:
- Poortinga, W., & Whitaker, L. (2018). Promoting the use of reusable coffee cups through environmental messaging, the provision of alternatives and financial incentives. Sustainability, 10(3), 873.
- Novoradovskaya, E., Mullan, B., Hasking, P., & Uren, H. V. (2021). My cup of tea: Behaviour change intervention to promote use of reusable hot drink cups. Journal of Cleaner Production, 284, 124675.
b) Elaborate on the theories referred to in the introduction, COM-B, TDF and BCW. It is important to reflect why these three models were chosen, how they demonstrated effectiveness previously, and provide some examples of specific components of the frameworks, not just descriptions. It would also be beneficial to elaborate further on how COM-B and TDF line up with BCW, as it is not particularly clear.
It is also important to clarify the aims of the research. For example, in "What are the influences on single-use and reusable cup use?" it is unclear as to what exactly 'influences' refer to. There is potnetial to formulate hypotheses for the survey part of the findings.
In Methods I was wondering about details of the conducted power analysis, e.g., for which statistical test was it conducted?
Regarding the Survey: it may be needed to insert another question as the very first one or as an inclusion criterion for the study, whether the participant consumes takeaway hot drinks at all. There is a risk to end up with skewed data if those who do not drink takeaway hot drinks would be completing the survey and it is not controlled for.
In the Procedure section it is unclear how exactly the participants would be selected: randomly or using a certain strategy?
I am very excited to read this paper once the data can be obtained!
