Paraphrasing occurs when you summarize key ideas from an article into your own words. Even though you are rephrasing the original writing, the ideas are not yours. You must give credit each time you rewrite the original source.
Since you are paraphrasing ideas from an article that supports your research paper, APA requires that you make it clear which ideas are yours and which come from your sources. A lengthy paraphrase of one or more paragraphs requires that you cite a source each time an idea comes from that source. It may seem awkward to keep citing the source at the end of each paraphrased sentence, but that is the only way that the reader can distinguish between your original ideas and those you borrow.
For this reason, you cannot cite only at the end of the paragraph.
Below are some examples that should help you:
Incorrect: (Citing only at the end of the paragraph)
Anxiety is a common result for patients with chronic illnesses, such as cancer, who ae undergoing treatment. Mind-body therapy has become a significant addition to conventional therapy that clinicians can use to help patients during treatment. Doctors can discuss alternative therapies with patients so they can consider what options might suit their needs. Once a patient has expressed an interest in a particular therapy, it is important to refer patients to appropriately experienced practitioners (Hart, 2013).
Correct but Awkward:

Much Better:
Anxiety is a common result for patients with chronic illnesses, such as cancer, who ae undergoing treatment (Hart, 2013). According to Hart (2013), mind-body therapy has become a significant addition to conventional therapy that clinicians can use to help patients during treatment. Hart (2013) claims that doctors can discuss alternative therapies with patients so they can consider what options might suit their needs.
