Is it correct that if you are paraphrasing an entire paragraph or more from one source in an APA paper, you must cite the source after every sentence?

I can’t find the information on any of the cites that I trust would give me the correct answer (purdue owl, etc).

In my paper I am describing an experiment that was done by three researchers. Because I am describing it in detail, it is taking more than one paragraph.

Below is the first paragraph cited in 2 different ways. Can someone verify for me which one of these is correct, or if neither of them is correct, what I should do to fix it?

The main problem in addiction therapy is figuring out how long to keep a drug abuser in the program long enough for it to work. One of the best ways to ensure this is to create a good therapeutic alliance, meaning that the client feels that he or she can trust the therapist and feels like they are in a non-judging, safe environment (Wesley, Minatrea, & Watson, 2009). In the study that I will be referencing, Wesley, Minatrea, & Watson arranged for participants who were seeking therapy for substance dependence in a residential treatment facility to be split into two groups; the control group who would receive traditional therapy, and the experimental group who would receive AAT. The 231 participants were of varying age groups, genders, races, income, education levels, and sexuality. There were participants who had been court ordered to receive treatment as well as participants who had personally chosen to receive treatment.

The therapy dog used was a Beagle mix named Mitzi Ann. Mitzi Ann was chosen for this experiment because of the “tricks” that she had been taught. Mitzi Ann was trained to retrieve a tissue from a tissue box and bring it to any participant who began crying or who sneezed. She naturally moved from client to client throughout the therapy sessions, making herself available for physical touch to anyone who wanted it. Physical touch can be very important in an addiction therapy setting because of the social stigma that many addicts deal with; they are often rejected by family and friends and many of the participants in this study had previously been homeless, had come directly out of jail, and had not experienced the comfort of home in some time.

or would I have to cite them at the end of every sentence, even when I’m describing the expiriment in paraphrase for an entire paragraph? Or could I just cite them at the end of each paraphrased paragraph describing the expiriment?
