What is the correct punctuation for the sentence regarding clients in the delayed-treatment condition?

Using quotation marks around the phrase regarding clients in the delayed-treatment condition is appropriate when directly quoting a term or a specific phrase from a source. In academic writing, especially in APA format, this signifies that the words are borrowed from another work and indicates the beginning and end of the quoted material. This not only gives credit to the original author but also helps to clarify that the enclosed content is not the writer's own wording, thereby maintaining academic integrity.

In this instance, if the phrase is a direct quote from a source, placing it within quotation marks ensures proper citation practices. It's an essential rule of APA style to quote direct phrases verbatim and to clearly differentiate them from the writer's explanations or analysis. This approach guides readers to understand the context and source of the information accurately.
