Understanding Abnormal Behavior

To understand what abnormal behavior is, we first have to understand what normal behavior is. Normal really is in the eye of the beholder, and most psychologists have found it easier to explain what is wrong with people then what is right. How so?

Psychology worked with the disease model for over 60 years, from about the late 1800s into the middle part of the 20th century. The focus was simple – curing mental disorders – and included such pioneers as Freud, Adler, Klein, Jung, and Erickson. These names are synonymous with the psychoanalytical school of thought. In the 1930s, behaviorism, under B.F. Skinner, presented a new view of human behavior. Simply, human behavior could be modified if the correct combination of reinforcements and punishments were used. This viewpoint espoused the dominant worldview of the time – mechanism – which presented the world as a great machine explained through the principles of physics and chemistry. In it, human beings serve as smaller machines in the larger machine of the universe.

Moving into the mid to late 1900s, we developed a more scientific investigation of mental illness, which allowed us to examine the roles of both nature and nurture and to develop drug and psychological treatments to “make miserable people less miserable.” Though this was an improvement, there were three consequences as pointed out by Martin Seligman in his 2008 TED Talk entitled, “The new era of positive psychology.” These are:

• “The first was moral; that psychologists and psychiatrists became victimologists, pathologizers; that our view of human nature was that if you were in trouble, bricks fell on you. And we forgot that people made choices and decisions. We forgot responsibility. That was the first cost.”
• “The second cost was that we forgot about you people. We forgot about improving normal lives. We forgot about a mission to make relatively untroubled people happier, more fulfilled, more productive. And “genius,” “high-talent,” became a dirty word. No one works on that.”
• “And the third problem about the disease model is, in our rush to do something about people in trouble, in our rush to do something about repairing damage, it never occurred to us to develop interventions to make people happier — positive interventions.”

Starting in the 1960s, figures such as Abraham Maslow and Carl Rogers sought to overcome the limitations of psychoanalysis and behaviorism by establishing a “third force” psychology, also known as humanistic psychology. As Maslow said,

“The science of psychology has been far more successful on the negative than on the positive side; it has revealed to us much about man’s shortcomings, his illnesses, his sins, but little about his potentialities, his virtues, his achievable aspirations, or his full psychological height. It is as if psychology had voluntarily restricted itself to only half its rightful jurisdiction, and that the darker, meaner half.” (Maslow, 1954, p. 354).

Humanistic psychology instead addressed the full range of human functioning and focused on personal fulfillment, valuing feelings over intellect, hedonism, a belief in human perfectibility, emphasis on the present, self-disclosure, self-actualization, positive regard, client centered therapy, and the hierarchy of needs. Again, these topics were in stark contrast to much of the work being done in the field of psychology up to and at this time.

In 1996, Martin Seligman became the president of the American Psychological Association (APA) and called for a positive psychology or one that had a more positive conception of human potential and nature. Building on Maslow and Roger’s work, he ushered in the scientific study of such topics as happiness, love, hope, optimism, life satisfaction, goal setting, leisure, and subjective well-being. Though positive and humanistic psychology have similarities, their methodology was much different. While humanistic psychology generally relied on qualitative methods, positive psychology utilizes a quantitative approach and aims to help people make the most out of life’s setbacks, relate well to others, find fulfillment in creativity, and find lasting meaning and satisfaction (https://www.positivepsychologyinstitute.com.au/what-is-positive-psychology).

So, to understand what normal behavior is, do we look to positive psychology for an indication, or do we first define abnormal behavior and then reverse engineer a definition of what normal is? Our preceding discussion gave suggestions about what normal behavior is, but could the darker elements of our personality also make up what is normal to some extent? Possibly. The one truth is that no matter what behavior we display, if taken to the extreme, it can become disordered – whether trying to control others through social influence or helping people in an altruistic fashion. As such, we can consider abnormal behavior to be a combination of personal distress, psychological dysfunction, deviance from social norms, dangerousness to self and others, and costliness to society.

How Do We Determine What Abnormal Behavior Is?

In the previous section we showed that what we might consider normal behavior is difficult to define. Equally challenging is understanding what abnormal behavior is, which may be surprising to you. A publication which you will become intimately familiar with throughout this book, the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders 5th edition, Text Revision (DSM-5-TR; 2022), states that, “Although no definition can capture all aspects of the range of disorders contained in DSM-5″ (pg. 13) certain aspects are required. These include:

• Dysfunction – Includes “clinically significant disturbance in an individual’s cognition, emotion regulation, or behavior that reflects a dysfunction in the psychological, biological, or developmental processes underlying mental functioning” (pg. 14). Abnormal behavior, therefore, has the capacity to make well-being difficult to obtain and can be assessed by looking at an individual’s current performance and comparing it to what is expected in general or how the person has performed in the past. As such, a good employee who suddenly demonstrates poor performance may be experiencing an environmental demand leading to stress and ineffective coping mechanisms. Once the demand resolves itself, the person’s performance should return to normal according to this principle.
• Distress – When the person experiences a disabling condition “in social, occupational, or other important activities” (pg. 14). Distress can take the form of psychological or physical pain, or both concurrently. Alone though, distress is not sufficient enough to describe behavior as abnormal. Why is that? The loss of a loved one would cause even the most “normally” functioning individual pain. An athlete who experiences a career-ending injury would display distress as well. Suffering is part of life and cannot be avoided. And some people who exhibit abnormal behavior are generally positive while doing so.
• Deviance – Closer examination of the word abnormal indicates a move away from what is normal, or the mean (i.e., what would be considered average and in this case in relation to behavior), and so is behavior that infrequently occurs (sort of an outlier in our data). Our culture, or the totality of socially transmitted behaviors, customs, values, technology, attitudes, beliefs, art, and other products that are particular to a group, determines what is normal. Thus, a person is said to be deviant when he or she fails to follow the stated and unstated rules of society, called social norms. Social norms change over time due to shifts in accepted values and expectations. For instance, homosexuality was taboo in the U.S. just a few decades ago, but today, it is generally accepted. Likewise, PDAs, or public displays of affection, do not cause a second look by most people unlike the past when these outward expressions of love were restricted to the privacy of one’s own house or bedroom. In the U.S., crying is generally seen as a weakness for males. However, if the behavior occurs in the context of a tragedy such as the Vegas mass shooting on October 1, 2017, in which 58 people were killed and about 500 were wounded while attending the Route 91 Harvest Festival, then it is appropriate and understandable. Finally, consider that statistically deviant behavior is not necessarily negative. Genius is an example of behavior that is not the norm.

Though not part of the DSM conceptualization of what abnormal behavior is, many clinicians add dangerousness to this list when behavior represents a threat to the safety of the person or others. It is important to note that having a mental disorder does not imply a person is automatically dangerous. The depressed or anxious individual is often no more a threat than someone who is not depressed, and as Hiday and Burns (2010) showed, dangerousness is more the exception than the rule. Still, mental health professionals have a duty to report to law enforcement when a mentally disordered individual expresses intent to harm another person or themselves. It is important to point out that people seen as dangerous are also not automatically mentally ill.

The Costs of Mental Illness

This leads us to wonder what the cost of mental illness is to society. The National Alliance on Mental Illness (NAMI) states that mental illness affects a person’s life which then ripples out to the family, community, and world. For instance, people with serious mental illness are at increased risk for diabetes, cancer, and cardiometabolic disease while 18% of those with a mental illness also have a substance use disorder. Within the family, an estimated 8.4 million Americans provide care to an adult with an emotional or mental illness with caregivers spending about 32 hours a week providing unpaid care. At the community level 21% of the homeless also have a serious mental illness while 70% of youth in the juvenile justice system have at least one mental health condition. And finally, depression is a leading cause of disability worldwide and depression and anxiety disorders cost the global economy $1 trillion each year in lost productivity (Source: NAMI, The Ripple Effect of Mental Illness infographic; https://www.nami.org/Learn-More/Mental-Health-By-the-Numbers).

In terms of worldwide impact, data from 2010 estimates $2.5 trillion in global costs, with $1.7 trillion being indirect costs (i.e., invisible costs “associated with income losses due to mortality, disability, and care seeking, including lost production due to work absence or early retirement”) and the remainder being direct (i.e., visible costs to include “medication, physician visits, psychotherapy sessions, hospitalization,” etc.). It is now projected that mental illness costs will be around $16 trillion by 2030. The authors add, “It should be noted that these calculations did not include costs associated with mental disorders from outside the healthcare system, such as legal costs caused by illicit drug abuse” (Trautmann, Rehm, & Wittchen, 2016). The costs for mental illness have also been found to be greater than the combined costs of somatic diseases such as cancer, diabetes, and respiratory disorders (Whiteford et al., 2013).

Christensen et al. (2020) did a review of 143 cost-of-illness studies that covered 48 countries and several types of mental illness. Their results showed that mental disorders are a substantial economic burden for societies and that certain groups of mental disorders are more costly than others. At the higher cost end were developmental disorders to include autism spectrum disorders followed by schizophrenia and intellectual disabilities. They write, “However, it is important to note that while disorders such as mood, neurotic and substance use disorders were less costly according to societal cost per patient, these disorders are much more prevalent and thus would contribute substantially to the total national cost in a country.” And much like Trautmann, Rehm, & Wittchen (2016) other studies show that indirect costs are higher than direct costs (Jin & Mosweu, 2017; Chong et al., 2016).

Defining Key Terms

Our discussion so far has concerned what normal and abnormal behavior is. We saw that the study of normal behavior falls under the providence of positive psychology. Similarly, the scientific study of abnormal behavior, with the intent to be able to predict reliably, explain, diagnose, identify the causes of, and treat maladaptive behavior, is what we refer to as abnormal psychology. Abnormal behavior can become pathological and has led to the scientific study of psychological disorders, or psychopathology. From our previous discussion we can fashion the following definition of a psychological or mental disorder: mental disorders are characterized by psychological dysfunction, which causes physical and/or psychological distress or impaired functioning, and is not an expected behavior according to societal or cultural standards.
