Learning Objectives. Define “psychological disorder” and summarize the general causes of disorder. Explain why it is so difficult to define disorder, and how the Diagnostic and Statistical Manual of Mental Disorders ( DSM) is used to make diagnoses. Describe the stigma of psychological disorders and their impact on those who suffer from them. The focus of this chapter and the next is, to many people, the heart of psychology.

This emphasis on abnormal psychology — the application of psychological science to understanding and treating mental disorders — is appropriate, as more psychologists are involved in the diagnosis and treatment of psychological disorder than in any other endeavour, and these are probably the most important tasks psychologists face. In 2012, approximately 2.8 million people, or 10.1% of Canadians aged 15 and older, reported symptoms consistent with at least one of six mental or substance use disorders in the past 12 months (Pearson, Janz, & Ali, 2013). At least a half billion people are affected worldwide. The six disorders measured by the Canadian Mental Health Survey were major depressive episode, bipolar disorder, generalized anxiety disorder, and abuse of or dependence on alcohol, cannabis, or other drugs. The impact of mental illness is particularly strong on people who are poorer, of lower socioeconomic class, and from disadvantaged ethnic groups. People with psychological disorders are also stigmatized by the people around them, resulting in shame and embarrassment, as well as prejudice and discrimination against them.

Thus the understanding and treatment of psychological disorder has broad implications for the everyday life of many people. Table 13.1, “Prevalence Rates for Psychological Disorders in Canada, 2012,” shows the prevalence, the frequency of occurrence of a given condition in a population at a given time, of some of the major psychological disorders in Canada. Prevalence Rates for Psychological Disorders in Canada, 2012, adapted by J.

Walinga from Statistics Canada 2013. In this chapter our focus is on the disorders themselves. We will review the major psychological disorders and consider their causes and their impact on the people who suffer from them. Then in Chapter 14, “Treating Psychological Disorders,” we will turn to consider the treatment of these disorders through psychotherapy and drug therapy. Defining Disorder A psychological disorder is an ongoing dysfunctional pattern of thought, emotion, and behaviour that causes significant distress, and that is considered deviant in that person’s culture or society (Butcher, Mineka, & Hooley, 2007). Psychological disorders have much in common with other medical disorders. They are out of the patient’s control, they may in some cases be treated by drugs, and their treatment is often covered by medical insurance. Like medical problems, psychological disorders have both biological (nature) as well as environmental (nurture) influences.

These causal influences are reflected in the bio-psycho-social model of illness (Engel, 1977). The bio-psycho-social model of illness is a way of understanding disorder that assumes that disorder is caused by biological, psychological, and social factors (Figure 13.1, “The Bio-Psycho-Social Model”).

The biological component of the bio-psycho-social model refers to the influences on disorder that come from the functioning of the individual’s body. Particularly important are genetic characteristics that make some people more vulnerable to a disorder than others and the influence of neurotransmitters. The psychological component of the bio-psycho-social model refers to the influences that come from the individual, such as patterns of negative thinking and stress responses.

The social component of the bio-psycho-social model refers to the influences on disorder due to social and cultural factors such as socioeconomic status, homelessness, abuse, and discrimination. Figure 13.1 The Bio-Psycho-Social Model.

The bio-psycho-social model of disorder proposes that disorders are caused by biological, psychological, and social-cultural factors. Figure 13.2 How Thin Is Too Thin? Psychology in Everyday Life: Combating the Stigma of Abnormal Behaviour Every culture and society has its own views on what constitutes abnormal behaviour and what causes it (Brothwell, 1981). The Old Testament Book of Samuel tells us that as a consequence of his sins, God sent King Saul an evil spirit to torment him (1 Samuel 16:14). Ancient Hindu tradition attributed psychological disorder to sorcery and witchcraft. During the Middle Ages it was believed that mental illness occurred when the body was infected by evil spirits, particularly the devil.

Remedies included whipping, bloodletting, purges, and trepanation (cutting a hole in the skull, Figure 13.3) to release the demons. Figure 13.3 Trepanation. Trepanation (drilling holes in the skull) has been used since prehistoric times in attempts to cure epilepsy, schizophrenia, and other psychological disorders. Until the 18th century, the most common treatment for the mentally ill was to incarcerate them in asylums or “madhouses.” During the 18th century, however, some reformers began to oppose this brutal treatment of the mentally ill, arguing that mental illness was a medical problem that had nothing to do with evil spirits or demons. In France, one of the key reformers was Philippe Pinel (1745-1826), who believed that mental illness was caused by a combination of physical and psychological stressors, exacerbated by inhumane conditions.

Pinel advocated the introduction of exercise, fresh air, and daylight for the inmates, as well as treating them gently and talking with them. Reformers such as Phillipe Pinel (1745-1826), Dorothea Dix (1802-1887), Richard M. Bucke (1837-1902), Charles K. Clarke (1857-1924), Clifford W. Beers (1876-1943), and Clarence M. Hincks (1885-1964) were instrumental in creating mental hospitals that treated patients humanely and attempted to cure them if possible (Figure 13.5). These reformers saw mental illness as an underlying psychological disorder, which was diagnosed according to its symptoms and which could be cured through treatment.

Dr Richard Bucke was appointed superintendent of the Asylum for the Insane in Hamilton in 1876 and a year later of the asylum in London, Ontario. He believed mental illness was a failure of the human biological adaptive process. In his attempts to reform the crude treatment of mentally ill patients he abandoned the practice of pacifying the inmates with alcohol or restraining them, and inaugurated regular cultural and sports events for patients.

Dr Charles Clarke was an assistant superintendent at the Hamilton asylum in the early 1880s, and later superintendent of the asylum at Kingston, Ontario. By 1887 he had changed the asylum from a jail to a hospital and was instructing nurses and attendants in the care of the mentally ill. By 1893 he was advocating that the term “asylum” be dropped and that special hospitals be constructed for the mentally ill.

Dr Clarence Hincks, born in St Mary’s, Ontario, was interested in mental health partly due to his own experiences with severe depression. In 1918, with Beers’s help, he organized the Canadian National Committee for Mental Hygiene, which later became the Canadian Mental Health Association.

Dix was a Massachusetts schoolteacher who wrote, lectured, and informed the public and legislators about the deplorable conditions in mental institutions like those shown in Figure 13.4. She was successful in influencing a number of state legislatures either to establish or improve their mental institutions, and because of her efforts a mental hospital was built in St. John’s, Newfoundland, in 1885. She also lobbied the Nova Scotia legislature and oversaw the building of a hospital for mental patients in that province. Phillipe Pinel was a French physician who became intensely interested in mental health in the 1770s. He took a psychological approach as opposed to the prominent biological approach that was the custom and introduced new forms of treatments that involved close contact with and careful observation of patients.

Pinel visited each patient up to several times a day, engaging them in lengthy conversations, and took careful notes in an effort to assemble a detailed case history and a natural history of the patient’s illness. At the time, his therapy was quite contrary to the usual practices of bleeding, purging, or blistering.

Figure 13.5 Portraits of Philippe Pine, Benjamin Rush, and Dorothea Dix. Reformers such as Philippe Pinel, Benjamin Rush, and Dorothea Dix fought the often brutal treatment of the mentally ill and were instrumental in changing perceptions and treatment of them. Despite the progress made since the 1800s in public attitudes about those who suffer from psychological disorders, people, including police, coworkers, and even friends and family members, still stigmatize people with psychological disorders.

A stigma refers to a disgrace or defect that indicates that person belongs to a culturally devalued social group. In some cases the stigma of mental illness is accompanied by the use of disrespectful and dehumanizing labels, including names such as crazy, nuts, mental, schizo, and retard. The stigma of mental disorder affects people while they are ill, while they are healing, and even after they have healed (Schefer, 2003). On a community level, stigma can affect the kinds of services social service agencies give to people with mental illness, and the treatment provided to them and their families by schools, workplaces, places of worship, and health-care providers. Stigma about mental illness also leads to employment discrimination, despite the fact that with appropriate support, even people with severe psychological disorders are able to hold a job (Boardman, Grove, Perkins, & Shepherd, 2003; Leff & Warner, 2006; Ozawa & Yaeda, 2007; Pulido, Diaz, & Ramirez, 2004). The mass media has a significant influence on society’s attitude toward mental illness (Francis, Pirkis, Dunt, & Blood, 2001). While media portrayal of mental illness is often sympathetic, negative stereotypes still remain in newspapers, magazines, film, and television. (See the following video for an example.) Television advertisements may perpetuate negative stereotypes about the mentally ill.

For example, in 2010 Burger King ran an ad called “The King’s Gone Crazy,” in which the company’s mascot runs around an office complex carrying out acts of violence and wreaking havoc.: The most significant problem of the stigmatization of those with psychological disorder is that it slows their recovery. People with mental problems internalize societal attitudes about mental illness, often becoming so embarrassed or ashamed that they conceal their difficulties and fail to seek treatment. Stigma leads to lowered self-esteem, increased isolation, and hopelessness, and it may negatively influence the individual’s family and professional life (Hayward & Bright, 1997). Despite all of these challenges, however, many people overcome psychological disorders and go on to lead productive lives. It is up to all of us who are informed about the causes of psychological disorder and the impact of these conditions on people to understand, first, that mental illness is not a “fault” any more than is cancer. People do not choose to have a mental illness.

Second, we must all work to help overcome the stigma associated with disorder. Organizations such as the Canadian Mental Health Association (CMHA) help by working to reduce the negative impact of stigma through education, community action, and individual support. Diagnosing Disorder: The DSM Psychologists have developed criteria that help them determine whether behaviour should be considered a psychological disorder and which of the many disorders particular behaviours indicate. These criteria are laid out in a 1,000-page manual known as the Diagnostic and Statistical Manual of Mental Disorders (DSM), a document that provides a common language and standard criteria for the classification of mental disorders (American Psychiatric Association, 2013). The DSM is used by therapists, researchers, drug companies, health insurance companies, and policymakers in Canada and the United States to determine what services are appropriately provided for treating patients with given symptoms. The first edition of the DSM was published in 1952 on the basis of census data and psychiatric hospital statistics. Since then, the DSM has been revised five times. The last major revision was the fourth edition ( DSM-IV), published in 1994, and an update of that document was produced in 2000 ( DSM-IV-TR).

Pdf

The fifth edition ( DSM-5) is the most recent edition and was published in 2013. The Medical Council of Canada transitioned to the DSM-5 recently (MCC, 2013). The DSM-IV-TR was designed in conjunction with the World Health Organization’s 10th version of the International Classification of Diseases ( ICD-10), which is used as a guide for mental disorders in Europe and other parts of the world. The DSM does not attempt to specify the exact symptoms that are required for a diagnosis. Rather, the DSM uses categories, and patients whose symptoms are similar to the description of the category are said to have that disorder. The DSM frequently uses qualifiers to indicate different levels of severity within a category. For instance, the disorder of mental retardation can be classified as mild, moderate, or severe.

Each revision of the DSM takes into consideration new knowledge as well as changes in cultural norms about disorder. Homosexuality, for example, was listed as a mental disorder in the DSM until 1973, when it was removed in response to advocacy by politically active gay rights groups and changing social norms. The current version of the DSM lists about 400 disorders.

Although the DSM has been criticized regarding the nature of its categorization system (and it is frequently revised to attempt to address these criticisms), for the fact that it tends to classify more behaviours as disorders with every revision (even “academic problems” are now listed as a potential psychological disorder), and for the fact that it is primarily focused on Western illness, it is nevertheless a comprehensive, practical, and necessary tool that provides a common language to describe disorder. Most insurance companies will not pay for therapy unless the patient has a DSM diagnosis. The DSM approach allows a systematic assessment of the patient, taking into account the mental disorder in question, the patient’s medical condition, psychological and cultural factors, and the way the patient functions in everyday life. Diagnosis or Overdiagnosis? ADHD, Autistic Disorder, and Asperger’s Disorder Two common critiques of the DSM are that the categorization system leaves quite a bit of ambiguity in diagnosis and that it covers such a wide variety of behaviours. Let’s take a closer look at three common disorders — attention-deficit/hyperactivity disorder (ADHD), autistic disorder, and Asperger’s disorder — that have recently raised controversy because they are being diagnosed significantly more frequently than they were in the past. Attention-Deficit/Hyperactivity Disorder (ADHD) Zack, aged seven years, has always had trouble settling down.

He is easily bored and distracted. In school, he cannot stay in his seat for very long and he frequently does not follow instructions. He is constantly fidgeting or staring into space. Zack has poor social skills and may overreact when someone accidentally bumps into him or uses one of his toys. At home, he chatters constantly and rarely settles down to do a quiet activity, such as reading a book.

Symptoms such as Zack’s are common among seven-year-olds, and particularly among boys. But what do the symptoms mean? Does Zack simply have a lot of energy and a short attention span? Boys mature more slowly than girls at this age, and perhaps Zack will catch up in the next few years. One possibility is for the parents and teachers to work with Zack to help him be more attentive, to put up with the behaviour, and to wait it out. But many parents, often on the advice of the child’s teacher, take their children to a psychologist for diagnosis.

If Zack were taken for testing today, it is very likely that he would be diagnosed with a psychological disorder known as attention-deficit/hyperactivity disorder (ADHD). ADHD is a developmental behaviour disorder characterized by problems with focus, difficulty maintaining attention, and inability to concentrate, in which symptoms start before seven years of age (Canadian Mental Health Association, 2014). Although it is usually first diagnosed in childhood, ADHD can remain problematic in adults, and up to 7% of university students are diagnosed with it (Weyandt & DuPaul, 2006). In adults the symptoms of ADHD include forgetfulness, difficulty paying attention to details, procrastination, disorganized work habits, and not listening to others. ADHD is about 70% more likely to occur in males than in females (Kessler, Chiu, Demler, & Walters, 2005), and is often comorbid with other behavioural and conduct disorders. The diagnosis of ADHD has quadrupled over the past 20 years, and it is now diagnosed in about one out of every 37 Canadian children. It is the most common psychological disorder among children in the world (Olfson, Gameroff, Marcus, & Jensen, 2003). ADHD is also being diagnosed much more frequently in adolescents and adults (Barkley, 1998). You might wonder what this all means.

Are the increases in the diagnosis of ADHD because today’s children and adolescents are actually more distracted and hyperactive than their parents were, due to a greater awareness of ADHD among teachers and parents, or due to psychologists and psychiatrists’ tendency to overdiagnose the problem? Perhaps drug companies are also involved, because ADHD is often treated with prescription medications, including stimulants such as Ritalin. Although skeptics argue that ADHD is overdiagnosed and is a handy excuse for behavioural problems, most psychologists believe that ADHD is a real disorder that is caused by a combination of genetic and environmental factors. Key Takeaways. More psychologists are involved in the diagnosis and treatment of psychological disorder than in any other endeavour, and those tasks are probably the most important psychologists face.

The impact on people with a psychological disorder comes both from the disease itself and from the stigma associated with disorder. A psychological disorder is an ongoing dysfunctional pattern of thought, emotion, and behaviour that causes significant distress and that is considered deviant in that person’s culture or society.

According to the bio-psycho-social model, psychological disorders have biological, psychological, and social causes. It is difficult to diagnose psychological disorders, although the DSM provides guidelines that are based on a category system. The DSM is frequently revised, taking into consideration new knowledge as well as changes in cultural norms about disorder. There is controversy about the diagnosis of disorders such as ADHD, autistic disorder, and Asperger’s disorder.
