ABNORMAL PSYCHOLOGY - What Is Art Therapy?

















Question: What Is Art Therapy?
Answer:
It may surprise you to learn that art can be an effective tool in mental health treatment. What could art possibly have to do withpsychotherapy? As an expressive medium, art can be used to help clients communicate, overcome stress, and explore different aspects of their own personalities. In psychology, the use of artistic methods to treat psychological disorders and enhance mental health is known as art therapy.
Art therapy integrates psychotherapeutic techniques with the creative process to improve mental health and well-being. The American Art Therapy Association describes art therapy as "a mental health profession that uses the creative process of art making to improve and enhance the physical, mental and emotional well-being of individuals of all ages. It is based on the belief that the creative process involved in artistic self-expression helps people to resolve conflicts and problems, develop interpersonal skills, manage behavior, reduce stress, increase self-esteem and self-awareness, and achieve insight."

When Did Art Therapy Originate?

While people have been using the arts as a way to express, communicate, and heal for thousands of years, art therapy only began to formalize during the middle of the 20th-century. Doctors noted that individuals suffering from mental illness often expressed themselves in drawings and other artworks, which led many to explore the use of art as a healing strategy. Since then, art has become an important part of the therapeutic field and is used in some assessment and treatment techniques.

When Is Art Therapy Used?

Art therapy can be used to treat a wide range of mental disorders and psychological distress. In many cases, it might be used in conjunction with other psychotherapy techniques such as group therapy or cognitive-behavioral therapy.
Some situations in which art therapy might be utilized include:
  • Children with learning disabilities

  • Adults experiencing severe stress

  • Children suffering from behavioral or social problems at school or at home

  • People experiencing mental health problems

  • Individuals suffering from a brain injury

  • Children or adults who have experienced a traumatic event

How Does Art Therapy Work?

An art therapist may use a variety of art methods including drawing, painting, sculpture, and collage with clients ranging from young children to the elderly. Clients who have experienced emotional trauma, physical violence, domestic abuse, anxiety, depression, and other psychological issues can benefit from expressing themselves creatively. Hospitals, private mental health offices, schools, and community organizations are all possible settings where art therapy services may be available.
You might also wonder how an art therapy session differs from the average art class. "In most art therapy sessions, the focus is on your inner experience—your feelings, perceptions, and imagination. While art therapy may involve learning skills or art techniques, the emphasis is generally first on developing and expressing images that come from inside the person, rather than those he or she sees in the outside world," explains Cathy Maldiochi in The Art Therapy Sourcebook . "And while some traditional art classes may ask you to paint or draw from your imagination, in art therapy, your inner world of images, feelings, thoughts, and ideas are always of primary importance to the experience."

How to Become an Art Therapist

Are you interested in a career in art therapy? While laws vary from state to state, in most cases you may need to first become a licensed clinical psychologist, professional counselor, or social worker in order to offer psychotherapy services. Start by checking with your state to learn more about the education, training, and professional credentials you will need to practice art therapy.
In the United States, the Art Therapy Credentials Board, Inc. (ATCB) offers credentialing programs allow art therapists to become registered, board certified or licensed art therapists, depending upon the state in which they live and work.
According to the American Art Therapy Association, the minimum requirements:
  1. A master's degree in art therapy, or
  2. A master's degree in counseling or a related field with additional coursework in art therapy
Additional post-graduate supervised experience is also required. You can learn more about the training and educational requirements to become an art therapist on the AATA website.

ABNORMAL PSYCHOLOGY - What Is Cognitive Behavior Therapy?

















Cognitive behavior therapy (CBT) is a type of psychotherapeutic treatment that helps patients understand the thoughts and feelings that influence behaviors. CBT is commonly used to treat a wide range of disorders including phobias, addiction, depression and anxiety.
Cognitive behavior therapy is generally short-term and focused on helping clients deal with a very specific problem. During the course of treatment, people learn how to identify and change destructive or disturbing thought patterns that have a negative influence on behavior.

Cognitive Behavior Therapy Basics

The underlying concept behind CBT is that our thoughts and feelings play a fundamental role in our behavior. For example, a person who spends a lot of time thinking about plane crashes, runway accidents, and other air disasters may find themselves avoiding air travel. The goal of cognitive behavior therapy is to teach patients that while they cannot control every aspect of the world around them, they can take control of how they interpret and deal with things in their environment.
Cognitive behavior therapy has become increasingly popular in recent years with both mental health consumers and treatment professionals. Because CBT is usually a short-term treatment option, it is often more affordable than some other types of therapy. CBT is also empirically supported and has been shown to effectively help patients overcome a wide variety of maladaptive behaviors.

Types of Cognitive Behavior Therapy

According to the British Association of Behavioural and Cognitive Psychotherapies, "Cognitive and behavioural psychotherapies are a range of therapies based on concepts and principles derived from psychological models of human emotion and behaviour. They include a wide range of treatment approaches for emotional disorders, along a continuum from structured individual psychotherapy to self help material."
There are a number of different approaches to CBT that are regularly used by mental health professionals. These types include:

The Components of Cognitive Behavior Therapy

People often experience thoughts or feelings that reinforce or compound faulty beliefs. Such beliefs can result in problematic behaviors that can affect numerous life areas, including family, romantic relationships, work, and academics. For example, a person suffering from low self-esteemmight experience negative thoughts about his or her own abilities or appearance. As a result of these negative thinking patterns, the individual might start avoiding social situations or pass up opportunities for advancement at work or at school.
In order to combat these destructive thoughts and behaviors, a cognitive-behavioral therapist begins by helping the client to identify the problematic beliefs. This stage, known as functional analysis, is important for learning how thoughts, feelings, and situations can contribute to maladaptive behaviors. The process can be difficult, especially for patients who struggle with introspection, but it can ultimately lead to self-discovery and insights that are an essential part of the treatment process.
The second part of cognitive behavior therapy focuses on the actual behaviors that are contributing to the problem. The client begins to learn and practice new skills that can then be put into use in real-world situations. For example, a person suffering from drug addiction might start practicing new coping skills and rehearsing ways to avoid or deal with social situations that could potentially trigger a relapse.
In most cases, CBT is a gradual process that helps a person take incremental steps towards abehavior change. Someone suffering from social anxiety might start by simply imagining himself in an anxiety-provoking social situation. Next, the client might start practicing conversations with friends, family, and acquaintances. By progressively working toward a larger goal, the process seems less daunting and the goals easier to achieve.

Uses of Cognitive Behavior Therapy

Cognitive behavior therapy has been used to treat people suffering from a wide range of disorders, including anxiety, phobias, depression, and addiction. CBT is one of the most researched types of therapy, in part because treatment is focused on highly specific goals and results can be measured relatively easily.
Cognitive behavior therapy is often best-suited for clients who are comfortable with introspection. In order for CBT to be effective, the individual must be ready and willing to spend time and effort analyzing his or her thoughts and feelings. Such self-analysis can be difficult, but it is a great way to learn more about how internal states impact outward behavior.
Cognitive behavior therapy is also well-suited for people looking for a short-term treatment option that does not necessarily involve pharmacological medication. One of the greatest benefits of cognitive-behavior therapy is that it helps clients develop coping skills that can be useful both now and in the future.

Criticisms of Cognitive Behavior Therapy

Initially, some patients suggest that while they recognize that certain thoughts are not rational or healthy, simply becoming aware of these thoughts does not make it easy to stop having them. It is important to note that CBT does not just involve identifying these thought patterns; it is focused on using a wide range of strategies to help clients overcome these thoughts. Such strategies may include journaling, role-playing, relaxation techniques, and mental distractions.

ABNORMAL PSYCHOLOGY - Who Can Provide Psychotherapy?

















Question: Who Can Provide Psychotherapy?
Answer: Providers of psychotherapy and other mental health services may hold a number of titles, credentials, or licensures. Job titles such as "Psychologist" and "Psychiatrist" require the individual to meet specific state and national requirements. Regulation of titles such as "Psychotherapist" and "Therapist" vary from state to state. For example, in the state of Oregon, use of the title "Psychotherapist" is restricted to individuals who are licensed by the Oregon Board of Psychological Examiners.

If you are interested in working in mental health or if you are seeking a therapist for treatment, it is important to understand the credentials, licensing requirements and certifications of therapy providers.

Psychiatrists

  • Qualifications include graduation from medical school followed by a resident program in psychiatric care.

  • Some psychiatrists are board-certified, indicating they have received additional training beyond medical school and psychiatric residency.

  • Psychiatrists can prescribe medication to clients.

Psychologists

  • Ph.D. psychologists have five years of graduate training in psychology.

  • Psy.D. psychologists have the same training as those with a Ph.D., but there is less emphasis on research and experimental methods.

  • Most states require one to two years of supervised experience after graduation for full licensure.

Counselors

  • Licensed counselors typically have two to three years of graduate training in counseling methods.

  • Specialty areas include marriage and family counseling, school counseling, community counseling and substance about counseling.

  • Many states require counselors to be licensed by National Board for Certified Counselors (NBCC), which can grant the title of National Certified Counselor.

Social Workers, LCSW

  • Licensed clinical social workers (LCSWs) have approximately two years of graduate training in therapy, as well as completion of an internship and supervised experience in the field.

  • Other social workers may have a Master's degree in social work as well as supervised clinical experience.

Advanced Psychiatric Nurses

  • Advanced psychiatric nurses hold a Master's degree or higher in psychiatric-mental health nursing.

  • These professionals are able to assess patients, diagnose disorders, provide psychotherapy, and prescribe medications in some states.

  • Advanced psychiatric nurses work as clinical nurse specialists or nurse practitioners and work in diverse settings including hospitals, private clinics, mental health settings, emergency psychiatric settings and substance abuse treatment centers.

ABNORMAL PSYCHOLOGY - Types of Therapy

















The popular conception of therapy is that of the classic talk therapy; a client, a couch and a psychologist with a notepad and pencil in hand. While some approaches do utilize this method, there are numerous types of therapy that can be used to help a client overcome problems. In all cases, the goal of therapy is to provide a nonjudgmental environment that allows the client and therapy provider to work together towards a mutually agreed upon set of goals.
The following are just a few of the many different types of therapy available.

Psychoanalytic Therapy

What is Psychoanalytic Therapy?
Psychoanalytic therapy is one of the most well-known treatment modalities, but it is also one of the most misunderstood by mental health consumers. Founded by Sigmund Freud, psychoanalytic therapists generally spend time listening to patients talk about their lives, which is why this method is often referred to as "talk therapy." The therapy provider will look for patterns or significant events that may play a role in the client’s current difficulties. Psychoanalysts believe that childhood events and unconscious feelings, thoughts and motivations play a role in mental illness and maladaptive behaviors.
Benefits of Psychoanalytic Therapy
While this type of therapy has many critics who claim that psychoanalytic therapy is too time consuming, expensive and generally ineffective, this treatment has several benefits as well. The therapist offers an empathetic and nonjudgmental environment where the client can feel safe in revealing feelings or actions that have led to stress or tension in his or her life. Oftentimes, simply sharing these burdens with another person can have a beneficial influence.

Cognitive-Behavioral Therapy

What is Cognitive-Behavioral Therapy?
Cognitive therapists tend to focus on specific problems. These therapists believe that irrational thinking or faulty perceptions cause dysfunctions. A cognitive therapist may work with a client to change thought patterns. This type of therapy is often effective for clients suffering from depression or anxiety.
Behavioral therapists work to change problematic behaviors that have been trained through years of reinforcement. A good example of behavioral therapy would be a therapist working with a client to overcome a fear of heights. The therapist would encourage the client to gradually face their fear of heights through experience. The client might first imagine standing on the roof of a tall building or riding an escalator. Next, the client would slowly expose themselves to greater and greater levels of their fear until thephobia diminishes or disappears entirely.
Benefits of Cognitive-Behavioral Therapy
Cognitive and behavioral approaches can be highly effective when treating specific problems. Oftentimes, cognitive and behavioral approaches are combined when treating a disorder. A therapist treating a client with social anxiety may help the client form more accurate thinking patterns as well as focusing on specific behaviors, such as social avoidance.

Group Therapy

What is Group Therapy?
Group therapy is a form of psychotherapy where two or more clients work with one or more therapists or counselors. This methods is a popular format for support groups, where group members can learn from the experiences of others and offer advice. This method is also more cost effective than individual psychotherapy and is oftentimes more effective.
Benefits of Group Therapy
It is common for those suffering from a mental illness or problem behavior to feel alone, isolated or different. Group therapy can help clients by providing a peer group of individuals that are currently experiencing the same symptoms or who have recovered from a similar problem. Group members can also provide emotional support and a safe forum to practice new behaviors.

ABNORMAL PSYCHOLOGY - What's the Difference Between a Psychologist and a Psychiatrist?

















Question: What's the Difference Between a Psychologist and a Psychiatrist?
Answer:
The question sounds like the setup for a joke, but it's an important difference to understand whether you are a student of psychology or a consumer searching for a mental health provider. The terms "psychologist" and "psychiatrist" are often used interchangeably to describe anyone who provides therapy services. While psychologists and psychiatrists both conductpsychotherapy and research, there are significant differences between the two professions.

Education, Training, and Credentials

The simplest answer lies in the educational background required for each profession. A psychiatrist has a degree in medicine and apsychologist has a doctoral-level degree in psychology. However, there are a number of other distinctions that make each profession quite unique.
Psychologists receive graduate training in psychology and pursue either a Ph.D. (Doctor of Philosophy) or Psy.D. (Doctor of Psychology) in clinical or counseling psychology. Doctorate programs typically take five to seven years to complete and most states require an additional one or two year long internship in order to gain licensure. Other states require an additional year or two of supervised practice before granting full licensure.
The title of "psychologist" can only be used by an individual who has completed the above education, training, and state licensure. Informal titles such as "counselor" or "therapist" are often used as well, but other mental health care professionals such as licensed social workerscan also claim these titles.
Psychiatrists are physicians that have specific training in the assessment, diagnosis, treatment, and prevention of mental illnesses. In order to become a psychiatrist, students first earn an undergraduate degree before they attend medical school and receive an M.D. After finishing their medical training, they also complete an additional four years of residency training in mental health. Some also receive additional training in a specific area of interest such as geriatric psychiatry, child and adolescent psychiatry, addictions, and other areas.

Prescribing Medications

A second important distinction between the two careers is that psychiatrists can prescribe medications, while in most states psychologists cannot. However, there has been a recent push to grant prescribing powers to psychologists. Some states such as New Mexico and Louisiana now grant prescribing privileges to medical psychologists holding a post-doctoral masters degree or equivalent in clinical psychopharmacology.
Kevin McGuinness, chairman of the Commissioned Corps Mental Health Functional Advisory Group, writes, "For those interested in a career in psychology as a prescriber, it is important to know that certain federal employees and uniformed commissioned officers (Army, Air Force, Public Health Service, Navy, etc.) that are licensed in one state as a medical psychologist may prescribe an any other state to which they are assigned by the federal government."

Which is Better?

If you are considering a career as a therapist, you will need to determine which career path is best for you. Are you interested in conducting psychotherapy, administering psychological tests, and conducting research? If so, a career as a psychologist may be the best choice for you.
On the other hand, if you have an interest in medicine and want to be able to prescribe medications to your patients, a career in psychiatry might be your ideal choice.
If you do not want to invest five to eight years in graduate training, consider pursuing a career as a licensed social worker or counselor. These professionals are also qualified to provide mental health services depending up training and experience. Both social work and counseling typically require two or three years of graduate study.
Psychiatric nursing is another great career option for students interested in medicine. Advanced Psychiatric Nurses hold a master's degree or higher in psychiatric-mental health nursing and are able to assess patients, diagnose disorders, provide psychotherapy, and prescribe medications.

ABNORMAL PSYCHOLOGY - A List of Psychological Disorders

















List and Descriptions of the Categories of Psychological Disorders


Psychological disorders, also known as mental disorders, are patterns of behavioral or psychological symptoms that impact multiple areas of life. These disorders create distress for the person experiencing these symptoms. The following list of psychological disorders includes some of the major categories of psychological disorders listed in the Diagnostic and Statistical Manual of Mental Disorders as well as several examples of each type of psychological disorder.

Adjustment Disorders

This classification of mental disorders is related to an identifiable source of stress that causes significant emotional and behavioral symptoms. The diagnostic criteria listed by the DSM-IV diagnostic criteria included:
  • (1) Distress that is marked and excessive for what would be expected from the stressor and
  • (2) Creates significant impairment in school, work or social environments.
In addition to these requirements, the symptoms must occur within three months of exposure to the stressor, the symptoms must not meet the criteria for an Axis I or Axis II disorder, the symptoms must not be related to bereavement and the symptoms must not last for longer than six months after exposure to the stressor.
The DSM-V (released in May of 2013) moved adjustment disorder to a newly created section of stress-related syndromes.


Dissociative Disorders
Anxiety Disorders

Anxiety disorders are those that are characterized by excessive and abnormal fear, worry and anxiety. In one recent survey published in the Archives of General Psychology1, it was estimated that as many as 18% of American adults suffer from at least one anxiety disorder.

A psychological disorder, also known as a mental disorder, is a pattern of behavioral or psychological symptoms that impact multiple life areas and/or create distress for the person experiencing these symptoms.


What Is the Purpose of Getting a Diagnosis?
How are Psychological Disorders Diagnosed?

The classification and diagnosis is an important concern for both mental health providers and mental health clients. While there is no single, definitive definition of mental disorders, a number of different classification and diagnostic criteria have emerged. Clinicians utilize theDiagnostic and Statistical Manual of Mental Disorders (DSM-IV TR), published by the American Psychiatric Association, to determine whether a set of symptoms or behaviors meets the criteria for diagnosis as a psychological disorder. The International Classification of Diseases (ICD-16), published by the World Health Organization, is also frequently used.
While some people may avoid seeking a diagnosis out of fear of social stigma, getting a diagnosis is an essential part of finding an effective treatment plan. A diagnosis is not about applying a label to a problem, it is about discovering solutions, treatments and information related to the problem.

How Prevalent Are Psychological Disorders?

Relatively recent research has revealed that psychological disorders are far more prevalent that previously believed. According to the National Institute of Mental Health (NIMH), approximately 26 percent of American adults over the age of 18 suffer from some type of diagnosable mental disorder in a given year.1
The 1994 National Comorbidity Survey (NCS) indicated that 30 percent of respondents had experienced symptoms of at least one psychological disorder in the previous year. The survey also indicated that nearly half of all adults experience some form of mental disorder at some point in their life.2

What Are the Different Types of Mental Disorders?

The DSM-IV TR describes approximately 250 different psychological disorders, most of which fall under a category of similar or related disorders. Some of the prominent diagnostic categories include eating disorders, mood disorders, somatoform disorders, sleep disorders, anxiety disorders and personality disorders.
