Community and Public Health Nursing
PRACTICUM
HEALTH PROBLEMS OF ADOLESCENTS.
Upon mastery of this chapter, you should be able to:
● Identify major health problems and concerns for school-age and adolescent
populations in the United States.
● Describe types of programs and services that promote health and prevent
illness and injury of school-age and adolescent
populations.
● State the recommended immunization schedule for school-age children
and give the rationale for the timing of each immunization.
● Describe some common roles and functions of school nurses.
● Evaluate the potential benefits of school-based health centers,
and discuss
possible parental or community objections.
Children and adolescents are important population
groups to community
health nurses because their physical and emotional health is vital to the future of
society and because they require
guidance and direction. Mortality
rates for children and adolescents have decreased dramatically
since the early 1900s, but morbidity
rates
remain high. Children and adolescents are vulnerable to many illnesses, injuries, and
emotional problems, often as a result
of a complex and stressful environment.
Violence
against children and deaths due to homicide
occur
in the United States at alarming rates. Unintentional injuries, suicide, and homicide are the
leading threats to life and
health for adolescents. Other health problems include alcohol and drug abuse, unplanned
pregnancies, STDs and HIV/AIDS,
and poor nutrition. All of these problems create major
challenges for the community health nurse who seeks to prevent illness and injury among
children and adolescents and
to promote their health. Chronic illnesses such as asthma and diabetes are important to
monitor. Irritating, somewhat common
problems, such as head lice and acne, can respond to
treatment and education. Health
services for children and adolescents span three categories:
prevention, health protection, and health promotion. The community health nurse plays a
vital role in each. Preventive
services include immunization programs,
parental
support services, family planning programs, services for those with STDs, and alcohol
and drug abuse prevention programs.
Health protection services include accident
and
injury control, programs to reduce environmental hazards,
control of infectious diseases, and services to protect children and adolescents from child
abuse and neglect. Health
promotion services include programs in nutrition and weight control; exercise and
physical fitness; smoking, alcohol,
and
drug abuse education; and stress control. Schoolbased health centers provide a convenient
place for the provision of
primary health care as well as health education and mental health counseling. The role of school nurses includes
three basic interventions. With
educational interventions such as nutrition teaching, nurses provide information and
encourage clients to act responsibly
on behalf of their own health. Nurses employ
persuasive
tactics to move clients toward more positive
health
behaviors by engineering interventions, such as encouraging consistent use of contraceptives by
adolescents. With
enforcement interventions, such as reporting and intervening in child abuse, nurses practice a
form of coercion to protect
children from threats to their health.
Nursing
of the school-age population involves providing health
services and health education and ensuring a
healthful
school environment. School nurses may provide these
services as part of their roles within health departments, or they may be hired by the school
district full-time. The increasingly
complex
needs of the school-age population and
the
collective accessibility for delivery of primary health care services to children in the
school setting are prompting schools
to hire nurses with advanced preparation as nurse practitioners
and credentialed school nurses expand their services to this aggregate.
The five stages and age ranges of human development relating
specifically to pediatric nursing are found in Table 1.

Development
Related to Pediatric Nursing
Principles of Growth and Development
At least
eight principles providing a framework for studying human development are
embedded within the issues and theories discussed in the following pages.
Although not all of these principles are proven by research, they are often
observed in children and generally assumed to be true (Hetherington &
Parke, 1993; Murray & Zentner, 2001).
1. Development is orderly and sequential. This principle suggests
that maturation follows a predictable and universal timetable. For example,
children learn to crawl before they learn to walk, and they learn to walk
before they learn to run. These changes occur rapidly during the first year of
life and slow during middle and late childhood. Even though the onset and
length of each developmental change vary among children, the basic sequence is
the same, allowing comparison to norms.
2. Development is directional. Skill development proceeds along two
different pathways: cephalocaudal and proximodistal. Cephalocaudal development
proceeds from the head downward. Therefore, areas closest to the brain or head
develop first, followed by the trunk, then legs and feet. For example, head
control is followed by sitting, then crawling, and then walking. Proximodistal
development proceeds from the inside out. Controlled movements closest to
the body's center (trunk, arms) develop before controlled movements distant to
the body (fingers). For example, grasping changes from using the entire hand to
just the fingers as infants get older.
3. Development is unique for each child. Ever)' child has a
unique timetable for physiological, psychosocial, cognitive, and moral development.
For example, some children can name four colors by the time the y are 3 years
old, whereas others cannot name four colors until they are 4V2 years old. Some
children walk well at 11 months; others do not walk well until they are 14
months old.
4. Development is interrelated. Physiological, psychosocial,
cognitive, and moral aspects of development affect and are affected by one
another. For example, central nervous system maturation is necessary for
cognitive development. Children cannot be independent in toileting if they are
not aware of the urge to void and cannot independently remove clothing.
5. Development becomes increasingly differentiated. This means
responses become more specific and skillful as the child grows. Young infants
respond to stimuli in a generalized way involving the entire body, whereas
older children respond to specific stimuli in a more refined and specialized
way. For example, infants will react with their entire body to pain by crying
and withdrawing, whereas a child is able to localize the pain, can often
identify its source, and may only withdraw the extremity experiencing the pain.
An infant will use the entire hand to grab a toy before developing the fine
motor ability necessary for the pincer grasp.
6. Development becomes increasingly integrated and complex. This
means, as new skills are gained, more complex tasks are learned. For example,
learning to drink from a cup initially requires eye-hand coordination, then
grasping, and then hand-mouth coordination. Infants' cooing is followed by
babbling, before these sounds are refined into the understandable speech of a
child.
7. Children are competent. They possess qualities and abilities
ensuring their survival and promoting their development. For example, newborns
can cough, sneeze, suck, swallow, digest, breathe, and elicit caretaking
responses from adults. Children make their needs known to caregivers in
increasingly sophisticated ways so that others know if they are cold, hungry,
or in pain.
8. New skills
predominate. This occurs because of the strong drive to practice and
perfect new abilities, especially early in life, when the child is not capable
of coping well with several new skills simultaneously. For example, when
children are learning to walk, talk, or feed themselves with utensils, their
attention and effort is focused on developing that one skill; they do not
usually learn to walk, talk, and feed themselves at the same time.
Issues of Human Development
Theories on
growth and development are often considered from the perspective of seven
issues. These issues help explain how development occurs and what humans are
like and can be applied to theories of human development. These issues answer
questions related to the importance of biology or the environment on development,
whether children are inherently good, bad, or actively involved in their own
development, if development occurs gradually or abruptly, if children are more
similar than different from one another, or if one's personality or way of
interacting with others remains stable throughout life. The issues discussed
include nature versus nurture, continuity versus discontinuity, passivity
versus activity, critical versus sensitive periods, universality versus context
specificity, assumptions about human nature, and behavioral consistency.
Nature versus Nurture
One of the more important and oldest issues discussed in human
development is the nature/nurture controversy. This debate concerns the
influence that biology (nature) and the environment (nurture) have on an
individual. Nature describes genetically inherited traits such as eye
color or body type, or disease such as cystic fibrosis or hemophilia. This view
sees development as predetermined by genetic factors and not altered by the
environment. A person believing in the principle of nature would suggest that
all normal children achieve identical developmental milestones at a similar
time due to maturational forces. If children differed in achieving these
milestones, it would be because of differences in their genetic makeup. Nurture
refers to the influences that the environment has on development, and
includes the influences that child-rearing methods, culture, learning
experiences, and society have on development. A person believing in the
principle of nurture would suggest that development can take different paths
depending on the experiences that an individual has over a lifetime.
Today, most developmentalists believe that both nature and nurture are
important, and that the relative contribution of each depends on the aspect of
development studied. Developmentalists today are also more concerned about how
biological and environmental factors interact to produce developmental
differences and changes, rather than the importance of one over the other .
Continuity versus Discontinuity
This issue addresses the nature of change across development. Continuity
suggests that change is orderly and built upon earlier experiences.
Development is a gradual and smooth process without abrupt shifts; the course of
development looks like a smooth growth curve. This issue also suggests early
and late development are connected; aggressive toddlers become aggressive
adults, curious infants become creative adolescents, and shy preschoolers
become introverted adults. Finally, continuity proposes that changes occur
quantitatively, or in degrees. For example, when children grow older, they
become taller, run faster, and learn more about the world around them.
Discontinuity suggests development is a series of discrete steps or
stages that elevate the child to a more advanced or higher level of functioning
with increased age. The course of development looks like a flight of stairs.
There is no connection between early and later development; behavior seen later
in life has replaced behavior seen earlier in life. For example, infants once
comfortable around strangers may come to fear them as they get older; a shy and
introverted preschooler may become an outgoing, extroverted adolescent.
Discontinuity would also argue that adult behavior cannot be predicted by
knowing what the person was like as a child. Finally, discontinuity implies
qualitative change, or changes that make the individual different as growth
occurs, as when a nonverbal infant becomes a toddler using language, or when a
prepubertal child becomes a mature adolescent.
Passivity versus Activity
This issue views the child as either a passive recipient shaped by
external environmental forces, or as internally driven and actively
participating in development. The passive view suggests that child-rearing
beliefs, practices, and behaviors cause children to be either shy or assertive.
Children become delinquent because of their association with an antisocial peer
group. Talented and creative teachers deserve credit for a child's interest in
mathematics or literature. Those disagreeing with this view believe children
purposefully, creatively, and actively seek experiences to control, direct, and
shape their development. Active children also modify caregiver, peer, and teacher
behavior (Figure 2).
Figure 2 Active children are interested in learning about other children's
projects and art work.
For example, an inquisitive, friendly child may encourage that same
behavior in an otherwise indifferent or unfriendly peer or adult.
Critical versus Sensitive Period
This issue concerns the importance of different time periods in
development, and asks if some phases are more important than others in
developing particular abilities, knowledge, or skills. The critical period refers
to a limited time span when a child is biologically prepared to acquire certain
behaviors, but needs the support of a suitably stimulating environment. Indeed,
there are some periods during development when children need to experience
certain sensory and social input if their development is to proceed normally.
The first 3 years of life are important for developing language, social, and
emotional responsiveness. If there is little or no opportunity for these
experiences during this time, children may have difficulty learning language,
developing close friendships, or having an intimate emotional relationship
later in life.
The sensitive period, on the other hand, is a time span that is
optimal for certain capacities to emerge when the individual is especially receptive
to environmental influences (Bornstein, 1989). Supporters of this view believe
some behaviors can be modified during early development. For example, infants
reared in an impoverished orphanage grew up without identifiable intellectual
deficits if they were placed in a stimulating and nurturing adoptive home
(Skeels, 1966). The fact that early experiences can be modified suggests humans
are malleable and adaptable and, for some areas of development, there are
sensitive rather than critical periods.
Universality
versus Context Specificity
The
importance of culture to development is embedded within this issue. Some
theorists believe an individual's culture has a profound influence on development.
Others suggest there are culture-free laws of development that apply to all
children in all cultures. For example, universality would say humans follow
similar developmental pathways regardless of their culture: language is
acquired and used at 11-14 months of age, cognitive changes preparing children
for school or higher learning occur during 5-7 years of age, and sexual
maturity is reached during the preteen or teenage years. Context specificity
on the other hand, would suggest there are differences in children related
to cultural values, beliefs, and experiences. For example, some societies
encourage early walking by providing opportunities to exercise and practice
these new skills, whereas in other societies carrying or swaddling infants is the
norm, thereby reducing the chance of walking until older.
Assumptions about Human Nature
The
doctrine of original sin used by Thomas Hobbes (1588-1679) to describe a
child's nature, suggests children are inherently evil and selfish egotists who
must be controlled by society. The doctrine of innate purity, proposed
by Jean Jaques Rousseau (1712-1778), suggests children are inherently good and
born without an intuitive sense of what is right and wrong. The doctrine of tabula
rasa, proposed by John Locke (1632-1704), suggests children are neither
good nor evil, but rather enter the world as a blank slate without inborn
tendencies, and are molded through life experiences. These assumptions are
based on 17th and 18th century social philosophers and rarely addressed
directly in theories of human development today. However, emphasis on positive
or negative aspects of a child's character and a particular theorist's belief
reflect an individual's orientation and assumptions about human nature. For
example, if one believes children are inherently caring and helpful, or on the
other hand, innately selfish, child-rearing practices would vary. Permissive
parents may believe children should be allowed to develop without interference
(innate purity), whereas authoritarian parents may take an approach that would
combat and control their child's selfish and aggressive impulses so they would
develop positive behaviors.
Behavioral Consistency
This issue
addresses whether or not a child's basic behavioral traits change according to
the setting (school, neighborhood, family). Some theorists suggest individual
personality characteristics and predispositions cause children to behave
similarly no matter the setting. Others suggest children's behavior changes
from one setting to another. Those supporting the former view would say a
particular child can always be described as honest, helpful, aggressive, or
independent, no matter the situation. The latter view would argue children's
behavior shifts according to the situation and who/what is present—friend in
need, angry caregiver or teacher, competitive game, or a difficult test.
THEORIES OF HUMAN DEVELOPMENT
The
following theoretical views present various ways of examining human development
during childhood and adolescence (Figure 3).
Figure 3. The
Eclectic Nature of Human Development
Freud and Psychosexual Development
Sigmond Freud (1856-1939), a Viennese physician,
originated the psychosexual theory emphasizing the importance of
unconscious motivation and early childhood experiences in influencing behavior,
and describing concepts related to personality and stages of development
(Freud, 1933). His ideas, considered radical when proposed early in the
twentieth century, became popular in the United States during the 1930s and
continue to influence thinking about human development today.
Central to
Freudian theory is the notion that two basic biological instincts (life and
death) motivate behavior, must be satisfied, and compete for supremacy (Freud,
1933). The life instinct aims for survival and is responsible for such life
sustaining activities as eating, breathing, copulation, and behavior that
expresses self preservation, love, and constructive conduct. The death instinct
on the other hand, is a destructive force expressed by self centered and cruel
behavior, hate, aggression, and destructive conduct. These instincts, the
source of psychic energy that drives human behavior, have three components: id,
ego, and superego. As the child matures, these components of personality become
more rational and reality bound (Freud, 1933).
During infancy,
all psychic energy resides in the id, the inborn element of personality
that is driven by selfish urges. The id obeys the "pleasure
principle," oriented toward maximizing pleasure and immediately satisfying
needs, even when biologic needs cannot be appropriately or realistically met.
The id is manifest as the irrational, selfish, impulsive part of personality
(Freud, 1933).
As the infant
develops, the ego or rational and controlling part of the personality
emerges. The ego operates according to the "reality principle"
as realistic ways of gratifying instinctual drives are discovered. Ego
functions allow individuals to be successful and include memory, cognition,
intelligence, problem solving, compromising, separating reality from fantasy,
and incorporating experiences and learning into future behavior. Ego
development continues during childhood and throughout the life span (Freud,
1933).
The third
component of personality is the superego or conscience, which emerges
when the child internalizes caregiver or societal values, roles, and morals.
Superego development begins in infancy, and becomes apparent in the preschool
and school-aged years when the child learns socially acceptable behavior. The
superego strives for perfection rather than for pleasure or reality. After the
superego emerges, children have a conscience that tells them the difference
between right and wrong, and which behaviors are socially acceptable outlets
for the id's undesirable impulses. The superego also serves as a disciplinarian
by creating feelings of remorse and guilt for transgressing rules, and self
praise and pride for adhering to rules (Freud, 1933).
Conflict among
the id, ego, and superego is inevitable throughout life. Mature, healthy
personalities, however, are in a dynamic balance, with the id communicating its
basic needs, the ego restraining the id until realistic ways are found to
satisfy these needs, and the superego determining whether or not the ego's
problem-solving strategies are morally acceptable. Freud believed defense
mechanisms, such as regression, displacement, projection, and sublimation were
created as escape valves to repress painful experiences or threatening thoughts
coming from the id's unsatisfied needs that were not managed by the ego or
superego (Freud, 1933).
To Freud, the
most important life instinct was the sex instinct, which changed its character
and focus according to biological maturation. (Freud's concept of sex and
sexuality was broader than what is implied in the use of these words today, and
indicates sexuality in its genital manifestations as well as any kind of
pleasure seeking.) As the sex instinct's psychic energy (libido) shifts
from one part of the body to another, the child passes through five stages of
development: oral, anal, phallic, latency, and genital (Table 2). Each stage is
related to a specific body part (erogenous zone) that brings primary pleasure
to the child during that stage. According to Freud, adult personality is
profoundly impacted by how each stage is managed.
Table 2. Stages of Freud's
Psychosexual Development
Application
Freud provides insight into human actions, and helps us understand others
by realizing all behavior is meaningful and may hide inner needs or conflicts.
Therefore, it is especially important to teach this information as well as
normal behavior for the various stages to parents. Since during infancy comfort
and pleasure are obtained through the mouth, it is important to offer babies a
pacifier if they are NPO, or a bottle, pacifiers, or the breast after painful
procedures. When hungry, they should be promptly fed (if not NPO). Providing
plastic or rubber rings or other toys suitable for teething infants are also
appropriate.
Toddlers are gratified by controlling body excretions. Therefore, when
caring for children between 1 and 3 years of age, asking about the status of
toileting and words and rituals used for elimination is important. It is wise
to provide a child-sized potty chair and avoid starting toilet training during
periods of illness or stress. In addition, toddlers should be reprimanded
carefully if toilet training is difficult or if the child has accidents. Finally,
parents need to be flexible and patient in toilet training and begin when the
toddler indicates readiness.
Preschool children are concerned about sexuality and initially identify
with the parent of the opposite gender. Nurses should teach parents that curiosity
about gender differences and masturbation is normal. In addition, nurses should
be aware of preschoolers who appear more comfortable with a particular nurse
(no matter the gender), attempt to accommodate that situation, and encourage
parents to participate in the care of their child. School-aged children and
adolescents should be encouraged to have contact with friends, and their
questions answered honestly. Privacy for both school age and adolescent clients
should be ensured during physical examinations or when they are changing
clothes or showering in gym class.
Erikson and
Psychosocial Development
Erik Erikson (1902-1994) acknowledged the contribution of biologic
factors to development, but felt that the environment, culture, and society
were also important. His psychosocial (epigenetic) theory of
development stresses the complexity of interrelationships existing between
emotional and physical variables during one's lifetime (Erikson, 1963).
Erikson agreed with many of Freud's ideas regarding basic instincts and
the three components of personality (id, ego, superego). In addition, he
believed development was stagelike, and conflict resolution was necessary at
each stage in order for the individual to successfully advance to the next
stage. In fact, Erikson's first five stages of development and the approximate
ages of each stage correspond closely with those outlined by Freud (Table 3).
Erikson differs from Freud, however, in that he believes children actively
adapt and explore their environment instead of being passively controlled and
molded by caregivers and society. Erikson also assumes humans are rational
creatures whose actions, feelings, and thoughts are controlled primarily by the
ego instead of the id, superego, or conflicts between the three components of
personality.
Table 3. Comparison of Stage Theories of Human Development
For Erikson, lifespan development consisted of eight sequential stages.
Five of these stages describe infants through adolescents (Table 4). Each stage
is dominated by major developmental conflicts or crises related to societal
demands and expectations that must be addressed or resolved before the
individual can progress to the next stage.
Table 4. Stages of Erikson's Psychosocial Theory of
Development
The resolution of each conflict or crisis might be positive (favorable
and growth enhancing), or negative (unfavorable, frustrating, and making later
development difficult). Erikson believed major conflicts occurring during each
stage are rarely completely resolved. Instead, they are of primary or dominant
importance during a particular stage and then become less important or dominant
as other conflicts arise in later stages. In addition, he suggests conflict is
rarely completely resolved positively. Rather, the positive resolution
predominates over the negative resolution during a particular stage. Failure to
successfully master a crisis or developmental task does not destine the child
to failure since delayed mastery is possible. It is true, however, that
difficulty at one stage may affect progress through later stages (Erickson, 1963).
Application
Erikson's theory provides us with a means of assessing and gaining
insight into five developmental crises children and adolescents face, and
allows us to use this knowledge to teach caregivers behaviors they can expect
to see in their children. It also helps us realize the importance of societal
influences on health and behavior, and that psychosocial development is a
lifelong process. Erikson's theory is easy to apply to practice. Health care
provides a variety of situations and opportunities where a child's progression
through stages can be facilitated, and caregivers taught how to encourage
positive resolution of each developmental crisis. Since meeting basic needs
(feeding, bathing, changing) in a timely and appropriate fashion during infancy
results in the development of trust, it is critical that feeding and hygiene
needs be met promptly. When an infant is ill, parents should be encouraged to
spend as much time as possible with their infant.
Figure 4. Letting toddlers feed themselves is important.
For toddlers, independence is increasing and self control gained by
maintaining familiar daily routines. Allowing opportunities for the child to
independently dress, feed, and do self-hygiene care is important (Figure 4). If
restraint for procedures or treatments
is necessary, explanations and comfort should be provided and caregivers
encouraged to participate. Love, approval, and praise are important for
toddlers and children in all stages.
Preschoolers like to initiate activities and remain curious and
interested in the world around them. Opportunities to explore, ask questions,
and create should be provided. Nurses should accept children's choices and
negative expression of feelings, answer their questions, and allow them to play
with medical equipment so their curiosity is satisfied and their knowledge
about experiences broadened.
For school-aged children, involvement and success in a variety of
activities provide a sense of self-worth and value. Nurses should provide the
school-aged child with opportunities for continuing school work if hospitalized
or ill, maintaining hobbies or activities, interacting with their peers, and
adjusting to limitations imposed by illness or hospitalization.
Primary care nurses need to be in touch with school nurses when a child
with a chronic condition is hospitalized and when this child is ready to return
home and to school.
Adolescents are searching for who they will become independent from their
parents. Nurses should allow adolescent clients to be as autonomous as
possible, encourage them to take responsibility for their own actions, support
their life choices, introduce them to other teens, and provide them with a
separate recreation or activity area if in an acute care setting. Parental
involvement in the care of adolescents is still important.
Sullivan and Interpersonal Development
Harry Stack Sullivan (1892-1949) focused on interpersonal relations as
important behavioral motivators and the source of psychological health. His interpersonal
theory posits that the self concept is the key to personality development.
He acknowledged the importance of the environment (especially the home),
and also emphasized the role of social approval and disapproval in forming a
child's self concept. Sullivan believed personality development was largely the
result of childhood experiences, interpersonal encounters, and the mother-child
relationship. How well physiological needs were met in an interpersonal situation
affected not only one's sense of satisfaction and security, but also allowed
anxiety to be avoided. Poor environmental interactions caused anxiety and
tension; a positive social relationship resulted in security, a major life goal
(Sullivan, 1953).
Stages of Interpersonal Development
Sullivan describes seven stages of interpersonal development (Sullivan,
1953); six relate specifically to infants through adolescents (Table 5).
Sullivan believed each stage prepared the personality for the next stage and
failure to successfully
achieve stage activities limited personality development and opportunities for
a successful life. Refer to Table
3 for a comparison of Sullivan's first six stages with Freud's and Erikson's
stages.
Table 5. Stages of Sullivan's Interpersonal Theory of
Development
Application
Sullivan also has relevance to the nursing care of children. Perhaps the
two most important points he made is to emphasize the significance of
interpersonal relations with others on personality development, and meeting the
child's basic needs in a timely and appropriate fashion. This does not mean,
however, that caregivers protect children from all discomforts or meet needs
before they are expressed. The key is to relieve unpleasant feelings associated
with basic needs so feelings of security and attachment result in a "good
me" rather than a "bad me." Sullivan also has helped us realize
the important place chums have in a school-aged child's life, and how this
experience is critical for developing interpersonal relationships later in
life.
Behavioral Perspective
The behavioral perspective posits that human actions and
interactions come from learned responses to environmental stimuli. Behavioral
theorists study human behavior in a laboratory setting and then apply this
information to the general population, and look for ways to alter or control
the environment to change, modify, or teach desired behaviors.
Pavlov and Classical Conditioning
Ivan Pavlov (1849-1936), a Russian physiologist, initially discovered
linkages between a stimulus and a response while studying a dogs response to
food. He learned a dog would respond (salivate) not only when he saw food
(unconditioned stimulus), but also when he saw the person who fed him or heard
a bell ring just before the food appeared (conditioned stimulus), because the
dog had learned that the bell or appearance of the man meant food would follow.
This learning to respond to a new stimulus the same way a familiar stimulus was
responded to is called classical conditioning, and suggests learning
occurs when a response that is already part of the organism s normal activities
(salivating) can be reproduced by an associated stimulus that previously would
not have produced it—for example, the presence of a person or the sound of a
bell (Crain, 2000; Murray & Zentner, 2001). Another example of classical
conditioning would be when an infant, seeing the spoon used for feeding,
becomes excited (waving hands and arms, kicking legs, making babbling sounds)
because the spoon is associated with being fed and the infant knows that
feeding time is coming soon.
Skinner and Operant Conditioning
Operant
conditioning, a term originated by B. F. Skinner (1904-1990), involves
behavioral changes due to either negative (punishment) or positive
(reinforcers) consequences rather than just the occurrence of a stimuli. If
behavior is rewarded, the likelihood of it reoccurring increases; if behavior
is punished, chances are it will not reoccur. Positive reinforcement includes
friendly smiles, praise, or special treats/privileges; punishment includes
criticism, a frown, or withdrawal of privileges. Skinner discovered behavioral
change became more permanent when consequences were provided intermittently
rather than continuously, and believed the essence of development involved
constantly acquiring new behaviors or habits due to reinforcing or punishing
stimuli. He emphasized why behaviors occur rather than simply describing the
behavior seen (Skinner, 1953).
Bandura and Social Learning
A third
kind of behaviorism is social learning, proposed by Albert Bandura (b. 1925).
According to this view, children learn by imitating and observing others (a
model), as well as by classical and operant conditioning. Social learning
theorists also believe behavior is influenced by the environment and learned
through various experiences. However, they do not believe behavioral change is
a mindless response to stimuli. Rather, they suggest personality, past
experiences, relationships with the model, the situation itself, and cognition
also impact behavioral change (Bandura, 1977). Cognition plays a part because
to successfully imitate behavior, a child must be capable of remembering,
rehearsing, and organizing the behavior seen. Children often will think about
connections between behavior and consequences and will likely be affected more
by what they believe will be the consequences rather than what the consequences
actually are. For example, learning to play a musical instrument is expensive
for families, and demanding and time consuming for children. However, children
and their parents continually tolerate the cost and inconvenience because they
are anticipating rewards once the child learns to play the instrument.
Bandura
also believes modeled behavior can be weakened or strengthened depending on
whether it is punished or rewarded. Bandura suggests observational learning
(learning that results from merely watching others), where children acquire a
variety of new behaviors when "models" are merely pursuing their own
interests and not attempting to teach, reward, or punish, is another important
method of learning behaviors. For example, research has shown children who
watch television violence frequently are more aggressive than those children
who do not watch very much television violence (Murray & Zentner, 2001).
Finally, Bandura found children tend to model behavior of children and adults
of their same gender more often than not, and males model behavior of others
more often than females do.
Application
Although
behaviorism has been criticized for denying the inherent capabilities of
persons to willfully respond to environmental situations and its relative
elementary nature, it is useful in health care. Positive behaviors can be reinforced
by encouragement, praise, and other rewards, and behaviors needing to be
altered or removed from a child's repertoire can be extinguished by either
ignoring or punishing. Parents commonly use these concepts when toilet training
or teaching their children cooperation, compromise, helpfulness, and empathy.
Some academic and preschool programs and parents use behavior modification and
time-out activities to modify and change undesirable behavior in children.
Operant conditioning can also help plan new or extinguish undesirable behavior
by providing specific guidelines, determining available reinforcers,
identifying responses acceptable for reinforcement, and planning how
reinforcers will be scheduled so behavior is repeated.
Social
learning theory is also readily applicable to health care. Children often will
cooperate with procedures (blood draws, X rays) if they see other children or
adults they emulate cooperating for the same procedure. Nurses can help parents
realize that their appearance and behavior is often imitated by their children,
and determine who might be significant role models for their children to
emulate. Finally, nurses need to demonstrate nurturing approaches or discipline
methods so parents learn effective parenting practices.
