Using Mobile Food Delivery Applications during the COVID-19 Pandemic: Applying the Theory of Planned Behavior to Examine Continuance Behavior

Round 1

Reviewer 1 Report

The work has merit, it is well structured. Nevertheless, I do believe that it can be enhanced.

In this article authors explore impact of the customers’ perception of food safety, social isolation, food delivery hygiene, and subject norms on the behavioral intention and continuance behavior to use mobile food delivery apps during the COVID-19 pandemic. Their conceptual framework is based on TAM and Theory of Planned Behavior.

There needs to be a clear justification of why the authors are using this conceptual framework in their work.

The abstract does not read very well. This is one of the most important sections of the manuscript. Please consider revising and editing the abstract since there are some grammatical errors as well.

Some of the survey questions could be brought into the paper – This would also add value and make it easier to follow. A link to the questionnaire can also be helpful – Authors mentioned this was sent Facebook, email and Zalo messages, perhaps later it was added to a webpage for better access.

The paper is well organized and written in a logical order. However, this manuscript needs major editing. There are extensive grammatical errors throughout this paper. The authors will need to re-edit this. There are some typos as well, for example:

Line 332: Survey is misspelled.

Other mistakes for example:

Line 37: Should this not be online to offline e-commerce is a new type of e-commerce in which ….

It is written the other way around: offline to online

Reviewer 2 Report

The idea of the study is interesting, in the context in which COVID-19 pandemic has opened up a significant market for food delivery services.

The current manuscript is written and presented with details in the research steps and results. Thus, the goal of this study (to figure out what variables influence customers' behavior and continuance behavior towards mobile food delivery apps) has been achieved.

However, I recommend that the authors make some minor changes:

- introduce the structure of the paper in the introduction, so that readers know the logical of the paper;

- pass the title to Figure 1;

- the reference (Siddiqui, 2020) from line 195, pass it to the reference format;

- check compliance with syntax rules.

Reviewer 3 Report

• Did you measure behavior or intention? Provide all measures used in this research as a table/appendix.
• Is the prediction power of your proposed model superior to the original TPB?
• The construct name “food delivery” in your figure is awkward.
• I wonder why the author omitted the use of belief construct as a predictor of subjective norm.
• Attitude, which is a salient factor in a socio-psychology model, is missing.
• The author mentioned TAM and TPB many times throughout the manuscript. Yet, the proposed theoretical framework does not include crucial factors within such theories.
• The paper deals with an interesting topic, but it simply reconfirms existing knowledge and relations in a new context. Given its limited new contribution to the field and scientific knowledge, I could not find much meaning of this research.

Round 2

Reviewer 3 Report

I thank the authors to conduct a revision.

Yet, the manuscript has not been much improved. The manuscript includes a lack of originality, which cannot be revisable. The manuscript should be entirely re-designed to be more theoretically and practically meaningful. Thus, I would not change my position of "reject".  Hope my decision does not discourage the authors.
