Not everyone who practices psychology is in agreement that Evidence-Based Practices are always the best options. Step 1. Back to the research journals! Find at least two articles that talk about the pros and cons of using evidence-based practices. Present a summary of your findings in the research in your discussion post that addresses the pros (at least one) and the cons (at least one) on this matter. Step 2. What are your opinions on this topic? Do you think all clinicians should be limited to evidence-based practices? Why or why not? Step 3. Cite your sources in APA format.

While I can't answer your assignment question/s for you, in this response I'll try to provide you with some tips and suggestions to assist you in researching and preparing your own discussion post.
Human beings are complex creatures, so it is understandable that not all psychological interventions will have the same impact on those receiving treatment. This doesn't mean, however, that there aren't a range of good reasons why evidence-based practices have come to be highly valued in the world of modern psychology.
Before you start your research, you might like to prepare a simple list on paper or on a computer where you can enter the pros (on one side of the list) and the cons (on the other side of the list) of evidence-based practices as you read through your selected articles. This will help you to keep your notes clear and organized, which will likely be useful when it comes time to create your discussion post.
Now I will briefly touch on one example of the benefits of evidence-based practice. (Note: this is not an example derived from a journal article, as requested in your initial question.) In a piece published in the OCD Newsletter (Spring, 2019), Dean McKay, PhD, Jonathan Abramowitz, PhD, and Eric Storch, PhD, wrote about instances where the use of therapeutic approaches that were not evidence-based caused clients' OCD symptoms to worsen.

In the context of psychology, it is logical that there is not a one-process-fits-all approach to evidence-based practice. Psychology consists of a vast number of fields: behavioral disorders, cultures, child and adolescent development, abnormal brain patterns, and so on. Psychology consists of both quantitative and qualitative measures, and approaches to diagnosis differ between clinical practices and research contexts.
I cannot provide points on every field of psychology related to evidence-based practice, but here are a few to get you started. Evidence-based practice in psychology (EBPP) has become an important process in healthcare systems and healthcare policy. EBPP is crucial to pharmacological treatment and research pertaining to emerging and experimental drug therapy. On the other hand, issues can arise with EBPP. For instance, studies pertaining to immigrants may be biased toward some cultural and ethnic groups rather than others. Additionally, immigrant social contexts can be vastly different across different urban and rural areas, which may not apply to others.
Some particularly helpful and authoritative sources you can refer to are the following: the NCBI (National Center for Biotechnology Information), Psychology Today, the American Psychological Association, and Psych Central. There are also a vast number of academic journals and publications that can be accessed through Google Scholar.
