Every professional discipline, from math and science to philosophy and psychology, bases its work and beliefs on theories. Most of these theories can best be described as explanations, hypotheses, or hunches, rather than testable facts. For students, the word theory may conjure up some dry, conceptual images, vaguely recalling the physicists’ theory of relativity or the geologists’ plate tectonics. Compared to most other theories, however, psychological theories are filled with familiar concepts since terms from psychological theories have filtered their way into parts of mainstream thinking and speech. Advertisements use the behaviorist ploy of linking a gorgeous, seductive woman to the family-style utilitarian minivan. And who has not attributed language mistakes to subconscious motivation? As the fictional king greets his queen: “Good morning, my beheaded …. I mean my beloved!” we comprehend the Freudian slip.


Dealing with other people is one of the most universally anxiety-provoking activities, and psychological theories provide plausible explanations for perplexing behavior. Maybe the guy at the front desk who never greets you in the morning does not really despise you; maybe he has an inferiority complex because his mother was cold and his father was absent from the home. In much the same way, patient stories are complex and always unique. It is useful to have a broad base of knowledge about personality development, human needs, the ingredients of mental health, contributing factors to mental illness, and the importance of relationships.


This chapter will provide you with snapshots of some of the most influential psychological theories. It will also provide an overview of the treatment, or therapy, they inspired and the contributions they have made to the practice of psychiatric mental health nursing. The theoretical journey begins with a look at Sigmund Freud, often referred to as the “father of psychoanalysis, and it moves on to Erik Erikson and Harry Stack Sullivan, who initially were devotees of Freud but later found Freudian theory lacking and took a divergent path. The chapter then focuses on the theory of the “mother of psychiatric nursing,” Hildegard Peplau. Abraham Maslow, a representative theorist from the humanistic approach to psychiatry, follows her work. Ivan Pavlov, John B. Watson, and B. F. Skinner represent the behaviorist approach. The final leg of this trip explores two dominant approaches to treating psychiatric illness: cognitive-behavioral therapy and biological therapies. Each of these theoretical approaches and therapies is evaluated for relevance to psychiatric mental health nursing. Let’s begin our expedition!



Psychoanalytic theories and therapies


Sigmund freud’s psychoanalytic theory


Sigmund Freud (1856-1939), an Austrian neurologist, revolutionized thinking about mental health disorders with his groundbreaking theory of personality structure, levels of awareness, anxiety, the role of defense mechanisms, and the stages of psychosexual development. Originally, he was searching for biological treatments for psychological disturbances and even experimented with using cocaine as medication. He soon abandoned the physiological approach and focused on psychological treatments. Freud came to believe that the vast majority of mental disorders were due to unresolved issues that originated in childhood. He arrived at this conclusion through his experiences treating people with hysteria, individuals who were suffering physical symptoms despite the absence of an apparent physiological cause.


As part his treatment, Freud initially used hypnosis, but this provided mixed therapeutic results. He then changed his approach to talk therapy, known as the cathartic method. Today, we refer to catharsis as “getting things off our chests.” Talk therapy evolved to include “free association,” which requires full and honest disclosure of thoughts and feelings as they come to mind. Dream analysis became an essential part of his therapy since Freud believed that urges and impulses of the unconscious mind were symbolically played out in dreams. Freud (1961, 1969) concluded that talking about difficult emotional issues had the potential to heal the wounds causing mental illness. Viewing the success of these therapeutic approaches led Freud to construct his psychoanalytic theory.



Levels of awareness


Through the use of talk therapy and free association, Freud came to the conclusion that there were three levels of psychological awareness in operation. He offered a topographic theory of how the mind functions, a description of the landscape of the mind. He used the image of an iceberg to describe these levels of awareness (Figure 2-1).

Personality structure


Freud (1960) delineated three major and distinct but interactive systems of the personality: the id, the ego, and the superego.






Defense mechanisms and anxiety


Freud (1969) believed that anxiety is an inevitable part of living. The environment in which we live presents dangers and insecurities, threats and satisfactions. It can produce pain and increase tension or produce pleasure and decrease tension. The ego develops defenses, or defense mechanisms, to ward off anxiety by preventing conscious awareness of threatening feelings.


Defense mechanisms share two common features: (1) they all (except suppression) operate on an unconscious level and (2) they deny, falsify, or distort reality to make it less threatening. Although we cannot survive without defense mechanisms, it is possible for our defense mechanisms to distort reality to such a degree that we experience difficulty with healthy adjustment and personal growth. Chapter 12 offers further discussions of defense mechanisms.



Psychosexual stages of development


Freud believed that human development proceeds through five stages from infancy to adulthood. His main focus, however, was on events that occur during the first 5 years of life. From Freud’s perspective, experiences during the early stages determined an individual’s lifetime adjustment patterns and personality traits. In fact, Freud thought that personality was formed by the time the child entered school and that subsequent growth consisted of elaborating on this basic structure. Freud’s psychosexual stages of development are presented in Table 2-1.



TABLE 2-1   


FREUD’S PSYCHOSEXUAL STAGES OF DEVELOPMENT















































STAGE (AGE) SOURCE OF SATISFACTION PRIMARY CONFLICT TASKS DESIRED OUTCOMES OTHER POSSIBLE PERSONALITY TRAITS
Oral (0-1 yr) Mouth (sucking, biting, chewing) Weaning Mastery of gratification of oral needs; beginning of ego development (4-5 mo) Development of trust in the environment, with the realization that needs can be met Fixation at the oral stage is associated with passivity, gullibility, and dependence; the use of sarcasm; may develop orally focused habits (e.g., smoking, nail-biting).
Anal (1-3 yr) Anal region (expulsion and retention of feces) Toilet training Beginning of development of a sense of control over instinctual drives; ability to delay immediate gratification to gain a future goal Control over impulses Fixation at the anal stage is associated with anal retentiveness (stinginess, rigid thought patterns, obsessive-compulsive disorder) or anal-expulsive character (messiness, destructiveness, cruelty).
Phallic (oedipal) (3-6 yr) Genitals (masturbation) Oedipus and Electra Sexual identity with parent of same sex; beginning of superego development Identification with parent of the same sex Fixation may result in reckless, self-assured, and narcissistic, person. Lack of resolution may result in inability to love and difficulties with sexual identity.
Latency (6-12 yr) — — Growth of ego functions (social, intellectual, mechanical) and the ability to care about and relate to others outside the home (peers of the same sex) The development of skills needed to cope with the environment Fixations can result in difficulty identifying with others and in developing social skills, leading to a sense of inadequacy and inferiority.
Genital (12 yr and beyond) Genitals (sexual intercourse) — Development of satisfying sexual and emotional relationship; emancipation from parents—planning of life goals and development of a sense of personal identity The ability to be creative and find pleasure in love and work Inability to negotiate this stage may derail emotional and financial independence, may impair personal identity and future goals, and disrupt ability to form satisfying intimate relationships.

Classical psychoanalysis


Classical psychoanalysis, as developed by Sigmund Freud, is seldom used today. Freud’s premise that all mental illness is caused by early intrapsychic conflict is no longer widely thought to be valid, and such therapy requires an unrealistically lengthy period of treatment (i.e., three to five times a week for nearly six years), making it prohibitively expensive and not insured for most. There are two concepts from classic psychoanalysis that are important for nurses to know: transference and countertransference (Freud, 1969).


Transference refers to feelings that the patient has toward health care workers that were originally held toward significant others in his or her life. When transference occurs, these feelings become available for exploration with the patient. Such exploration helps the patient to better understand certain feelings and behaviors. Countertransference refers to unconscious feelings that the health care worker has toward the patient. For instance, if the patient reminds you of someone you do not like, you may unconsciously react as if the patient were that individual. Countertransference underscores the importance of maintaining self-awareness and seeking supervisory guidance as therapeutic relationships progress. Chapter 10 talks more about countertransference and the nurse-patient relationship.



Psychodynamic therapy


Psychodynamic therapy follows the psychoanalytic model by using many of the tools of psychoanalysis, such as free association, dream analysis, transference, and countertransference; however, the therapist has increased involvement and interacts with the patient more freely than in traditional psychoanalysis. The therapy is oriented more to the here and now and makes less of an attempt to reconstruct the developmental origins of conflicts (Dewan, Steenbarger, & Greenberg, 2011). Psychodynamic therapy tends to last longer than other common therapeutic modalities and may extend for more than 20 sessions, which insurance companies often reject.


The best candidates for psychodynamic therapy are relatively healthy and well-functioning individuals, sometimes referred to as the “worried well,” who have a clearly circumscribed area of difficulty and are intelligent, psychologically minded, and well motivated for change. Patients with psychosis, severe depression, borderline personality disorders, and severe character disorders are not appropriate candidates for this type of treatment. Supportive therapies, which are within the scope of practice of the basic level psychiatric nurse, are useful for these patients. A variety of supportive therapies are described in chapters concerning specific disorders (Chapters 11 to 24).


At the start of treatment, the patient and therapist agree on what the focus will be and concentrate their work on that focus. Sessions are held weekly, and the total number of sessions to be held is determined at the outset of therapy. There is a rapid, back-and-forth pattern between patient and therapist, with both participating actively. The therapist intervenes constantly to keep the therapy on track, either by redirecting the patient’s attention or by interpreting deviations from the focus to the patient.


Brief therapies share the following common elements:




Erik erikson’s ego theory


Erik Erikson (1902-1994), an American psychoanalyst, was also a follower of Freud; however, Erikson (1963) believed that Freudian theory was restrictive and negative in its approach. He also stressed that an individual’s development is influenced by more than the limited mother-child-father triangle and that culture and society exert significant influence on personality. According to Erikson, personality was not set in stone at age 5, as Freud suggested, but continued to develop throughout the life span.


Erikson described development as occurring in eight predetermined and consecutive life stages (psychosocial crises), each of which consists of two possible outcomes (e.g., industry vs. inferiority). The successful or unsuccessful completion of each stage will affect the individual’s progression to the next (Table 2-2). For example, Erikson’s crisis of industry versus inferiority occurs from the ages of 7 to 12. During this stage, the child’s task is to gain a sense of personal abilities and competence and to expand relationships beyond the immediate family to include peers. The attainment of this task (industry) brings with it the virtue of confidence. The child who fails to navigate this stage successfully is unable to master age-appropriate tasks, cannot make a connection with peers, and will feel like a failure (inferiority).

Implications for psychiatric mental health nursing


Erikson’s developmental model is an essential component of patient assessment. Analysis of behavior patterns using Erikson’s framework can identify age-appropriate or arrested development of normal interpersonal skills. A developmental framework helps the nurse know what types of interventions are most likely to be effective. For example, children in Erikson’s initiative-versus-guilt stage of development respond best if they actively participate and ask questions. Older adults respond to a life-review strategy that focuses on the integrity of their life as a tapestry of experience. In the therapeutic encounter, individual responsibility and the capacity for improving one’s functioning are addressed. Treatment approaches and interventions can be tailored to the patient’s developmental level.



Interpersonal theories and therapies


Harry stack sullivan’s interpersonal theory


Harry Stack Sullivan (1892-1949), an American-born psychiatrist, initially approached patients from a Freudian framework, but he became frustrated by dealing with what he considered unseen and private mental processes within the individual. He turned his attention to interpersonal processes that could be observed in a social framework. Sullivan (1953) defined personality as behavior that can be observed within interpersonal relationships. This premise led to the development of his interpersonal theory.


According to Sullivan, the purpose of all behavior is to get needs met through interpersonal interactions and to decrease or avoid anxiety. He defined anxiety as any painful feeling or emotion that arises from social insecurity or prevents biological needs from being satisfied. Sullivan coined the term security operations to describe measures the individual employs to reduce anxiety and enhance security. Collectively, all of the security operations an individual uses to defend against anxiety and ensure self-esteem make up the self-system.


There are many parallels between Sullivan’s notion of security operations and Freud’s concept of defense mechanisms. Both are processes of which we are unaware, and both are ways in which we reduce anxiety. Freud’s defense mechanism of repression, however, is an intrapsychic activity, whereas Sullivan’s security operations are interpersonal relationship activities that can be observed.



Implications for psychiatric mental health nursing


Sullivan’s theory is the foundation for Hildegard Peplau’s nursing theory of interpersonal relationships examined later in this chapter. Sullivan believed that therapy should educate patients and assist them in gaining personal insight. Sullivan first used the term participant observer, which underscores that professional helpers cannot be isolated from the therapeutic situation if they are to be effective. Sullivan would insist that the nurse interact with the patient as an authentic human being. Mutuality, respect for the patient, unconditional acceptance, and empathy, which are considered essential aspects of modern therapeutic relationships, were important aspects of Sullivan’s theory of interpersonal therapy.


Sullivan also demonstrated that a psychotherapeutic environment characterized by an accepting atmosphere that provided numerous opportunities for practicing interpersonal skills and developing relationships is an invaluable treatment tool. Group psychotherapy, family therapy, and educational and skill training programs, as well as unstructured periods, can be incorporated into the design of a psychotherapeutic environment to facilitate healthy interactions. This method is used today in virtually all residential and day hospital settings.



Interpersonal psychotherapy


Interpersonal psychotherapy is an effective short-term therapy derived from the school of psychiatry that originated with Adolph Meyer and Harry Stack Sullivan. The assumption is that psychiatric disorders are influenced by interpersonal interactions and the social context. The goal of interpersonal psychotherapy is to reduce or eliminate psychiatric symptoms (particularly depression) by improving interpersonal functioning and satisfaction with social relationships (Dewan, Steenbarger, & Greenberger, 2011). Interpersonal psychotherapy has proved successful in the treatment of depression. Treatment is predicated on the notion that disturbances in important interpersonal relationships (or a deficit in one’s capacity to form those relationships) can play a role in initiating or maintaining clinical depression. In interpersonal psychotherapy, the therapist identifies the nature of the problem to be resolved and then selects strategies consistent with that problem area. Four types of problem areas have been identified (Hollon & Engelhardt, 1997):




Hildegard peplau’s theory of interpersonal relationships in nursing


Hildegard Peplau (1909-1999) (Figure 2-2), influenced by the work of Sullivan and learning theory, developed the first systematic theoretical framework for psychiatric nursing in her groundbreaking book Interpersonal Relations in Nursing (1952). Peplau not only established the foundation for the professional practice of psychiatric nursing but also continued to enrich psychiatric nursing theory and work for the advancement of nursing practice throughout her career.
