A debate rages in psychology. It is not one of the usual kind, dwelling on a specific aspect of the mind or a new drug, but a controversy dealing with the very foundations of psychology. The issue is determining how psychologists should treat patients and on what psychologists base their choices. Some feel that they must be empirically-supported treatments, treatments backed by hard data and scientifically supported. Others feel that this standard for treatments is much too confining for the complex field of psychology and that many good treatments cannot be backed by hard data. The American Psychological Association President Task Force on Evidence-Based Treatment came out with a plan for psychology that effectively maintains a high scientific standard but allows for a variety of research designs to be used in determining how to treat a patient. This plan of evidence-based practice in psychology (EBPP) is a strong standard for psychology because it allows patients to receive science-backed treatment that is still personalized.
EBPP “is the integration of the best available research with clinical expertise in the context of patient characteristics, culture, and preferences” (APA Task Force 2006). The first major facet of EBPP is the use of the best available research. For many, this might imply only randomized clinical trials (RCTs), and opponents have argued that RCTs are too narrow a type of study for psychology. A very valid point, this had been addressed in the new EBPP standard. Multiple types of research are included, ranging from public health and ethnographic research, to systematic case studies, to qualitative research, to meta-analyses (APA Task Force 2006).

This systematic review conducted by Takeda A, Taylor SJC, Taylor RS, Khan F, Krum H, Underwood M, (2012) sourced twenty-five trials, and the overall number of people of the collective trials included was 5,942. Interventions were classified and assessed using the following headings.-
“At its core evidence based ‘anything’ is concerned with using valid and relevant information in decision making” “high quality research is the most important source of valid information”. Psychological Association (2006, p. 273) defines EBP as "the integration of the best available research with clinical expertise in the context of patient characteristics, culture and preferences. " When caring for patients it is fundamentally important to have a good selection of up to date evidence Based Practice clinical articles to support research strategies, this allows professionals to assemble the most recent and accurate information known which enables them to make decisions tailored to the individual’s plan of care. It is essential to have clinical expertise and have the involvement of the individual patient, they must have full engagement and incorporation in order to have the accurate evaluation.... ... middle of paper ...
The disorder which is being treated is actually strengthened to the point of a serious mental illness. Similarly, in today’s society, medical and psychological advice may have the same effect. Medical technology and practice have progressed considerably since the time of the “Yellow Wallpaper.” This is not to say that today’s physicians are infallible. Perhaps some of today’s treatments are the “Yellow Wallpaper” of the future.
230) in EBP. Clinical opinion, together with the best relevant research evidence, provides the framework to for the best patient outcome. The nurse’s clinical opinion is acquired through knowledge and skills developed from undergraduate, graduate, or continuing education, clinical experience, and clinical practice (Melnyk & Fineout-Overholt, 2010). Clinical opinion also includes internal evidence, which is generated within a clinical setting from quality improvement outcomes, management initiatives or EBP implementation projects (Melnyk & Fineout-Overholt, 2010). Nurses use their clinical opinion when they identify each patient’s condition, individual risks, personal values and expectations, benefits of possible interventions, and gather evidence for EBP. When searching for the best available evidence, there is a hierarchy in the strength of evidence. The highest level of evidence usually comes from a systematic review or an evidence-based clinical practice guideline based on a systematic review. Systematic reviews provide the strongest evidence through a summary combining the results from many relevant, unbiased studies, to answer a particular clinical question. Nurses critically assess the individual studies, to gather the best evidence available for patient care. Systematic

Cognitive Behavioral Therapy appears to be a new treatment, although its roots can be traced to Albert Ellis’s Reason and Emotion in Psychotherapy, published in 1962. Cognitive therapy assumes that thoughts precede actions and false self-beliefs cause negative emotions. It is now known that most depression treatments have cognitive components to them, whether they are recognized or not. In the 1970’s many psychologists began using cognitive components to describe depression. From there, they developed cognitive forms to treat depression with impressive results (Franklin, 2003).
According to APA (2005), "evidence-based practice in psychology (EBPP) is the integration of the best available research with clinical expertise in the context of patient characteristics, culture, and preferences."
Evidence-based practice is important to consider when researching for interventions, further knowledge, or help to guide a new idea in the health professions. Evidence-based practice is comprised of three significant concepts: respect and awareness for the targeted population’s values, previous clinical practice or experience with that population, and systematic research to establish a better understanding of what is already known about the study’s focus. These concepts are all taken into consideration when designing and conducting a study because it provides a more valid and credible source for others.
There are some key distinctions between Randomized Controlled Trials (RCT) in a psychotherapeutic context and a medical context. There are key differences between the design of an RCT to evaluate a new drug and an RCT to evaluate a new form of couples’ therapy. However, it is important to begin by defining and understanding the importance of RCT in research (O'Brien, 2013).
Research indicates that efforts to reconcile science and practice in psychology since the Boulder conference in 1949 have mostly failed (Hayes, 1999). The scientist-practitioner (SP) ideal claims that practitioners should consume new research, evaluate their own methods as well as research and share their findings with other practitioners and scientists (Hayes et al, 1999). The SP gap has implications in a managed-care system in that it can make professionals accountable, ensures research is relevant to practice and provides structure and a theoretical framework for practitioners; without these, there is risk of losing accountability, the profession to the dominant scientific paradigm and government funding (Perez, 1999). Such obstacles to an integrated model in practice include, a lack of understanding of the model, the inherent split due to naturally different interests of scientists and practitioners, inefficiencies of traditional evidence in the clinical setting and differing epistemological attitudes of scientists and practitioners. In light of this, it will be argued that in the era of managed care, a more pragmatic local clinical model is suited for psychological practice.

“Legal, Ethical and Professional Issues” (Chapter 15) is an interesting chapter in the textbook “Abnormal Psychology.” Just like the name of the chapter, it helps understand legal, ethical, and professional issues related to the practice of psychology. This is very important because by offering service a psychologist is responsible for the people that are under his or her care, that even goes for people participating for research. Psychologist have authority to practice in their area of expertise, using methods that are not harmful to their recipients and “ that preferably have a strong scientific basis” and never doing treatments that are unorthodox and will put their patients health and safety in any more jeopardy. This also gives patients
Evidence-based medicine (EBM) has been described as “the conscientious, explicit, and judicious use of current best evidence in making decision about the care of individual patients” . Evidence-Based Practice is a thoughtful integration of the best available evidence, coupled with clinical expertise. It enables one to address healthcare questions with an evaluative and qualitative approach. It is about applying the best available research evidence in provision of health, behavior and education services to enhance outcomes. Evidence-Based practice is about performing the best possible practice in order to provide the best possible care .

The Science of Psychology “Psychology is the scientific study of mind, brain and behaviour. Some of what you do learn may seem like ‘common sense’, or at least familiar to you because you are learning about topics in which you can relate to. However some things you may believe is true, but is incorrect. The way we know this is through the application of scientific methods.” Mark Leary suggests that the subject matter of psychology is much more familiar to most people than is the subject matter of physics or biology; we see behaviour all around us.
