DeWayne has decided to seek psychotherapy for some personal difficulties he has been having. While on the telephone with one possible clinician, he asks her to describe the kind of treatment approach that she uses with clients. "I don’t limit myself to a single theory or approach," the therapist answers. "Instead I operate in a(n) _________ fashion, integrating various treatment approaches based on the specific needs of each client."

According to my research on the different types of psychological approaches, I can say that based on the information provided within the question Dewayne seems to be operating in an eclectic fashion. Eclecticism is an approach (like mentioned in the question) that instead of staying on a strict treatment or set of assumptions, it integrates different treatment approaches based on many theories, styles, and ideas in order to gain a better understanding of something and find the best possible solution.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.
