Eating Disorders
• Anorexia Nervosa• Bulimia• Obesity
![Page 3: Chapter 14](https://reader035.vdocuments.site/reader035/viewer/2022070419/56815d3c550346895dcb41e9/html5/thumbnails/3.jpg)
4 characteristics often observed in victims of anorexia nervosa
• Most often between 14 and 18 years old• Primarily female• Often have perfectionist tendencies• Face a real risk of death
![Page 4: Chapter 14](https://reader035.vdocuments.site/reader035/viewer/2022070419/56815d3c550346895dcb41e9/html5/thumbnails/4.jpg)
Social History of Anorexia Nervosa
• 1920s, “flapper” styles - eating disorders increased
• increasing prevalence of restrictive eating disorders in the 20th century, in the richer, more industrialized countries with thriving fashion industries
• True anorexia nervosa extremely rare in economically deprived groups and during wars and famines
![Page 5: Chapter 14](https://reader035.vdocuments.site/reader035/viewer/2022070419/56815d3c550346895dcb41e9/html5/thumbnails/5.jpg)
Personality Traits Associated with Anorexia Nervosa
• Perfectionist tendencies• Excessive self-criticism, guilt, depression• Driven by need to be thin • Only a few had history of being overweight• Can run in families
![Page 6: Chapter 14](https://reader035.vdocuments.site/reader035/viewer/2022070419/56815d3c550346895dcb41e9/html5/thumbnails/6.jpg)
The Course of Anorexia Nervosa
• Most describe experiences that they believe prompted or precipitated their unusual eating behavior
• onset usually quite sudden• Despite even strong objections from others,
anorexics deny that they are thin and continue behavior
• True anorexic pursues the destructive routine until physically unable to go on
![Page 7: Chapter 14](https://reader035.vdocuments.site/reader035/viewer/2022070419/56815d3c550346895dcb41e9/html5/thumbnails/7.jpg)
Etiology of Anorexia Nervosa
• Why do seemingly trivial occurrences trigger their anorexia?
• Despite much study, the etiology of anorexia nervosa remains unclear– genetic factors
– hormonal and endocrine problems
– obsessive-compulsive tendencies, depression,
– Neither genetic nor environmental influences can be ruled out
![Page 8: Chapter 14](https://reader035.vdocuments.site/reader035/viewer/2022070419/56815d3c550346895dcb41e9/html5/thumbnails/8.jpg)
Treatment of Anorexia Nervosa
• correct the individual’s nutrition problem and achieve medical stabilization
• Restore a normal diet, which can be difficult if patients resist
• Treatment must address a variety of factors since the weight and nutrition problems may be symptoms of other persistent psychological difficulties
• Therapy approaches often include family counseling. Family therapy seems to have more lasting effects
![Page 9: Chapter 14](https://reader035.vdocuments.site/reader035/viewer/2022070419/56815d3c550346895dcb41e9/html5/thumbnails/9.jpg)
Bulimia Nervosa
• Bulimia vs. Anorexia– Bulimia Nervosa: frequent episodes of
uncontrolled binge eating alternately purging. Can co-occur with Anorexia Nervosa
– With Bulimia, individuals usually maintain weight close to appropriate level; with anorexia individual greatly underweight
![Page 10: Chapter 14](https://reader035.vdocuments.site/reader035/viewer/2022070419/56815d3c550346895dcb41e9/html5/thumbnails/10.jpg)
• With Bulimia individuals fluctuate between gaining and loosing weight
• With Anorexia, individuals suffer extreme, life-threatening, weight loss.
![Page 11: Chapter 14](https://reader035.vdocuments.site/reader035/viewer/2022070419/56815d3c550346895dcb41e9/html5/thumbnails/11.jpg)
Etiology of Bulimia Nervosa
• Causes of bulimia are somewhat unclear at this time.
• Preoccupation with food and have a persistent urge to eat
• Those with bulimia seem to have more affective disturbance, particularly depression, than most people.
• Higher than normal level of substance abuse, and some report a history of sexual abuse.
• Similar to anorexia, bulimia probably stems in part from cultural and social pressures to be thin
![Page 12: Chapter 14](https://reader035.vdocuments.site/reader035/viewer/2022070419/56815d3c550346895dcb41e9/html5/thumbnails/12.jpg)
Treatment of Bulimia Nervosa
• medical evaluation of the individual should be undertaken at the outset.
– may be ruptures in the gastric or esophageal areas due to vomiting
– metabolic complications from either the vomiting or the abuse of laxatives
– Serious dental complications include erosion of tooth enamel from highly acidic vomit
![Page 13: Chapter 14](https://reader035.vdocuments.site/reader035/viewer/2022070419/56815d3c550346895dcb41e9/html5/thumbnails/13.jpg)
• Approaches to bulimia have included medication and various combinations of education, counseling, and behavior management
• Antidepressants are helpful in reducing binge eating, despite a substantial relapse rate when discontinued
• Various strategies are used in behavioral therapy approaches
• Training in self-monitoring
![Page 14: Chapter 14](https://reader035.vdocuments.site/reader035/viewer/2022070419/56815d3c550346895dcb41e9/html5/thumbnails/14.jpg)
• Cognitive-behavioral therapies
– basic behavioral management
– interrupting the disordered eating and then examining connections between certain cognitions and eating
– self-monitoring training and management of self-reinforcement contingencies
– relapse prevention and the use of multiple interventions Obesity
![Page 15: Chapter 14](https://reader035.vdocuments.site/reader035/viewer/2022070419/56815d3c550346895dcb41e9/html5/thumbnails/15.jpg)
Obesity
• Obese individuals have excess body fat and weigh approximately 30% more than is considered normal
• 5 – 10% of preschool children are obese• 27% of ages 6-11 are obese• 22% of teenagers• Prevalence especially among children has
increased substantially in last 15 years
![Page 16: Chapter 14](https://reader035.vdocuments.site/reader035/viewer/2022070419/56815d3c550346895dcb41e9/html5/thumbnails/16.jpg)
Childhood Obesity
• Serious health risk because it usually precedes a lifelong battle with obesity
• Depression• Social maladjustment
![Page 17: Chapter 14](https://reader035.vdocuments.site/reader035/viewer/2022070419/56815d3c550346895dcb41e9/html5/thumbnails/17.jpg)
Causes of Obesity
• Theories vary and often appear to be in conflict
• One view hereditary or constitutional condition
• Physiologically, there seem to be two types of obesity
– Hyperplastic obesity occurs when an individual has an abnormally high number of fat cells
– Hypertrophic obesity occurs when individuals are overweight primarily because of extremely enlarged fat cells.
![Page 18: Chapter 14](https://reader035.vdocuments.site/reader035/viewer/2022070419/56815d3c550346895dcb41e9/html5/thumbnails/18.jpg)
• Biological or physiological explanations feature the inheritance of a tendency toward obesity or slimness
• Many view learned behavior as an important cause of obesity
• Research suggests that obesity in youngsters does predict adult obesity
![Page 19: Chapter 14](https://reader035.vdocuments.site/reader035/viewer/2022070419/56815d3c550346895dcb41e9/html5/thumbnails/19.jpg)
• Being grossly overweight has psychological con-sequences as well as physical dangers
– negative physical self-perceptions
– score lower on general self-worth than non-obese peers.
![Page 20: Chapter 14](https://reader035.vdocuments.site/reader035/viewer/2022070419/56815d3c550346895dcb41e9/html5/thumbnails/20.jpg)
Treatment of Obesity
• Solutions and treatments for being overweight that might seem uncomplicated on the surface, often fail in the context of chronic obesity
– behavioral therapies
– medical treatments
![Page 21: Chapter 14](https://reader035.vdocuments.site/reader035/viewer/2022070419/56815d3c550346895dcb41e9/html5/thumbnails/21.jpg)
• Treatment must be approached in a systematic fashion
– multidisciplinary team (perhaps consisting of a physician, nutritionist, psychologist, and exercise therapist) is more effective
– The ability to monitor one’s own behavior is important
![Page 22: Chapter 14](https://reader035.vdocuments.site/reader035/viewer/2022070419/56815d3c550346895dcb41e9/html5/thumbnails/22.jpg)
Pharmacological Treatments
• Drugs that suppress appetite often have a number of undesirable or intolerable side effects
– lost weight is rapidly regained once the medication is discontinued
– Amphetamine-based medications that suppress appetite, increase activity, and heighten mood have been popular in both over-the-counter and prescription forms
• The benefits may be short-lived
![Page 23: Chapter 14](https://reader035.vdocuments.site/reader035/viewer/2022070419/56815d3c550346895dcb41e9/html5/thumbnails/23.jpg)
Surgical Interventions
• restrict stomach capacity, either by stapling procedures or by inserting balloon-type devices into the gastric cavity
– These approaches should be employed only in the most severe cases when other therapies have been unsuccessful
![Page 24: Chapter 14](https://reader035.vdocuments.site/reader035/viewer/2022070419/56815d3c550346895dcb41e9/html5/thumbnails/24.jpg)
Behavioral interventions
• Multifaceted behavioral treatment successfully treated obese children
• Children only age group for whom weight-reduction programs of any type have produced lasting benefits
• Behavioral programs tend to focus on managing eating behavior rather than attempting to change personality
![Page 25: Chapter 14](https://reader035.vdocuments.site/reader035/viewer/2022070419/56815d3c550346895dcb41e9/html5/thumbnails/25.jpg)
• Self-monitoring capacity
– Obese people frequently do not realize the unsuitability of the foods they consume and how quickly and often they eat
– Self-monitoring allows the person to become conscious of behaviors that contribute to undesirable eating, which can then be targeted for modification
![Page 26: Chapter 14](https://reader035.vdocuments.site/reader035/viewer/2022070419/56815d3c550346895dcb41e9/html5/thumbnails/26.jpg)
Toileting Problems
• Encopresis: Abnormal or unacceptable patterns of fecal expulsion by children beyond the age of toilet training and lacking organic pathology
• Enuresis: Recurrent bed-wetting or wetting of clothing at least twice a week for 3 months, diagnosed in children over 5
![Page 27: Chapter 14](https://reader035.vdocuments.site/reader035/viewer/2022070419/56815d3c550346895dcb41e9/html5/thumbnails/27.jpg)
Encopresis
• Retentive encopresis: an excessive retention of fecal material
• Non-retentive encopresis: uncontrolled expulsion of feces (incontinence) resulting in soiled clothing and bedding
• discontinuous, or secondary, encopresis• continuous, or primary, encopresis • Distinctions are very important in trying to
establish causation and devise treatment
![Page 28: Chapter 14](https://reader035.vdocuments.site/reader035/viewer/2022070419/56815d3c550346895dcb41e9/html5/thumbnails/28.jpg)
Treatment of Encopresis
• medical• psychoanalytic• behavioral
![Page 29: Chapter 14](https://reader035.vdocuments.site/reader035/viewer/2022070419/56815d3c550346895dcb41e9/html5/thumbnails/29.jpg)
Medical treatment
• emphasize direct physical control of fecal matter using enemas, laxatives, and stool softeners along with modified diet and sometimes pediatric counseling
• In some cases, medication employed to control bowel actions
• Most view encopresis as a combined physiological and behavioral problem
• Multimodal treatments may include behavioral shaping as well as the physical control techniques mentioned above
![Page 30: Chapter 14](https://reader035.vdocuments.site/reader035/viewer/2022070419/56815d3c550346895dcb41e9/html5/thumbnails/30.jpg)
Enuresis
• DSM-IV-TR cites prevalence for 5 – 10% for children at 5 years of age, 3 – 5% by age 10 and a lingering 1% of 15 year olds
• Most clinicians view urinary incontinence after about 3 to 5 years of age as a problem
![Page 31: Chapter 14](https://reader035.vdocuments.site/reader035/viewer/2022070419/56815d3c550346895dcb41e9/html5/thumbnails/31.jpg)
Functional Nocturnal Enuresis
• May happen during the day• Connection between sleep and urinary
incontinence• Considerable attention given to the
relationship between enuresis and sleep patterns
• Some literature relates sleep cycles and sleep abnormalities to enuresis
![Page 32: Chapter 14](https://reader035.vdocuments.site/reader035/viewer/2022070419/56815d3c550346895dcb41e9/html5/thumbnails/32.jpg)
The Psychodynamic
• interprets enuresis as a symptom of an inner conflict
• Effectiveness of psychoanalytic treatment has been poorly documented, and there is little research evidence for a success rate
![Page 33: Chapter 14](https://reader035.vdocuments.site/reader035/viewer/2022070419/56815d3c550346895dcb41e9/html5/thumbnails/33.jpg)
Medical explanations
• Include developmental or maturational lag, genetic influences, abnormalities of the urinary tract, and a deficit in cortical control
![Page 34: Chapter 14](https://reader035.vdocuments.site/reader035/viewer/2022070419/56815d3c550346895dcb41e9/html5/thumbnails/34.jpg)
Treatment
• Medications have been used
– Fluvoxamine is one popular alternative
• Behavioral approaches focus on the environmental contingencies related to urination.
– Urine alarms viewed as treatment of choice when combined with other treatments
![Page 35: Chapter 14](https://reader035.vdocuments.site/reader035/viewer/2022070419/56815d3c550346895dcb41e9/html5/thumbnails/35.jpg)
Sleep Disorders
• May occur in 30-45% of very young children
• Specific sleeping difficulties, such as insomnia, are reported by a similar proportion of adults
![Page 36: Chapter 14](https://reader035.vdocuments.site/reader035/viewer/2022070419/56815d3c550346895dcb41e9/html5/thumbnails/36.jpg)
Normal Sleep Cycle
• 2 distinct states– REM sleep: period during which rapid eye
movements occur and an individual dreams
– NREM sleep: lacks rapid eye movements, made up of 4 distinguishable stages
• Stage 1 : transitional period between wakefulness and sleep
• Stages 2, 3, and 4: characterized by differences in amount and type of brain-wave activity, generally spoken of as increasing in “depth” of sleep
![Page 37: Chapter 14](https://reader035.vdocuments.site/reader035/viewer/2022070419/56815d3c550346895dcb41e9/html5/thumbnails/37.jpg)
Parasomnias
• sleep disruptions associated with specific parts of the sleep cycle, stages of sleep, or sleep-wake shifts
• Activation of physiological systems at inappropriate times during the sleep-wake cycle”
• Relate to cognitive processes
![Page 38: Chapter 14](https://reader035.vdocuments.site/reader035/viewer/2022070419/56815d3c550346895dcb41e9/html5/thumbnails/38.jpg)
Nightmares and Night Terrors
• Sleep disorders in the parasomnia category • For some children, sleep disturbances are
frequent, persistent, and intense, and are then considered serious enough to be considered disorders
• tend to happen at different times of night and during different sleep stages. from ordinary dreams
![Page 39: Chapter 14](https://reader035.vdocuments.site/reader035/viewer/2022070419/56815d3c550346895dcb41e9/html5/thumbnails/39.jpg)
Differences between nightmares and night terrors
• Children experiencing night terrors typically sleep through the episode, even though their behavior is extremely agitated.
• Eyes are often wide open, as though they were staring at something in terror; they make grimaces and exhibit considerable physical movement, sometimes running about the room frantically; they may also shout and scream.
![Page 40: Chapter 14](https://reader035.vdocuments.site/reader035/viewer/2022070419/56815d3c550346895dcb41e9/html5/thumbnails/40.jpg)
• In nightmares, Children’s movements and verbalization much more subdued, typically restricted to moaning and slight movements in bed
![Page 41: Chapter 14](https://reader035.vdocuments.site/reader035/viewer/2022070419/56815d3c550346895dcb41e9/html5/thumbnails/41.jpg)
• Nightmares followed by a period during which the child is awake, recognizes people and surroundings, can provide a coherent account of what has transpired, and can remember the contents of the dream
• Night terrors followed by instant and peaceful sleep, lack of recognition of people and surroundings, and frequently, complete amnesia regarding both contents and occurrence
![Page 42: Chapter 14](https://reader035.vdocuments.site/reader035/viewer/2022070419/56815d3c550346895dcb41e9/html5/thumbnails/42.jpg)
Causes of nightmares and night terrors
• Largely unknown at this time• Theories
– sexual impulses that are not understood by the individual or experiences in a previous life
– associated with a variety of other conditions such as bronchial asthma, milk intolerance, night-time feeding, and genetic disposition
– multiple causes appear to be
![Page 43: Chapter 14](https://reader035.vdocuments.site/reader035/viewer/2022070419/56815d3c550346895dcb41e9/html5/thumbnails/43.jpg)
Sleep-Walking Disorder (Somnambulism)
• Somnambulism and night terrors have a number of common features; not unusual to find both problems in the same child
• Can create serious problems since children can place themselves in danger by walking in unsafe places such as balconies and stairways
• senses are not functioning in a manner that would protect them from falling or other types of accidents
![Page 44: Chapter 14](https://reader035.vdocuments.site/reader035/viewer/2022070419/56815d3c550346895dcb41e9/html5/thumbnails/44.jpg)
• Most often attributed to some type of emotional stress
• Treatment has followed several approaches with varying degrees of success
![Page 45: Chapter 14](https://reader035.vdocuments.site/reader035/viewer/2022070419/56815d3c550346895dcb41e9/html5/thumbnails/45.jpg)
Dyssomnias
• Sleep disorders in which the affected individual has significant and chronic difficulty related to the “amount, quality, or timing of sleep”
![Page 46: Chapter 14](https://reader035.vdocuments.site/reader035/viewer/2022070419/56815d3c550346895dcb41e9/html5/thumbnails/46.jpg)
Primary Insomnia
• Involves a problem in falling asleep that has a duration of at least a month, causes substantial impairment in several areas of functioning, and is not related to substance effects or a general medical condition
• Seems to begin in the early adult years and is relatively rare during childhood or adolescence
![Page 47: Chapter 14](https://reader035.vdocuments.site/reader035/viewer/2022070419/56815d3c550346895dcb41e9/html5/thumbnails/47.jpg)
Causes
• Anxiety or worrying is a significant contributor to insomnia
• Some evidence suggests that stress, anxiety, and panic attacks are more frequent among individuals with serious insomnia conditions
![Page 48: Chapter 14](https://reader035.vdocuments.site/reader035/viewer/2022070419/56815d3c550346895dcb41e9/html5/thumbnails/48.jpg)
Treatments
• Medication widely employed, but with mixed results
• Non-pharmacological treatments have the advantage of avoiding harmful side effects and placing the patient in greater control
• Comprehensive behavioral treatment packages have had high success rates
![Page 49: Chapter 14](https://reader035.vdocuments.site/reader035/viewer/2022070419/56815d3c550346895dcb41e9/html5/thumbnails/49.jpg)
Narcolepsy
• Disorder in which individuals encounter “sleep attacks” at times when they are trying to stay awake
– often thought of as excessive sleep, but should more correctly be viewed as inappropriate sleep
![Page 50: Chapter 14](https://reader035.vdocuments.site/reader035/viewer/2022070419/56815d3c550346895dcb41e9/html5/thumbnails/50.jpg)
Cause of Narcolepsy
• Largely eluded researchers to date
– One factor that has been identified relates to disturbances of REM sleep
![Page 51: Chapter 14](https://reader035.vdocuments.site/reader035/viewer/2022070419/56815d3c550346895dcb41e9/html5/thumbnails/51.jpg)
Treatment of Narcolepsy
• Primarily drug therapy• Non-pharmacological treatments, such as
behavior management and diet alteration, are only recently getting attention in the literature, and considerable research is needed to establish their effectiveness
![Page 52: Chapter 14](https://reader035.vdocuments.site/reader035/viewer/2022070419/56815d3c550346895dcb41e9/html5/thumbnails/52.jpg)
Speech Disorders
• Delayed Speech• Phonological (articulation) disorders• Stuttering (fluency disorder)
![Page 53: Chapter 14](https://reader035.vdocuments.site/reader035/viewer/2022070419/56815d3c550346895dcb41e9/html5/thumbnails/53.jpg)
Definitions
• Defective speech refers to speech behavior that is sufficiently deviant from normal or accepted speaking patterns that it attracts attention and adversely affects communication for either the speaker or the listener
![Page 54: Chapter 14](https://reader035.vdocuments.site/reader035/viewer/2022070419/56815d3c550346895dcb41e9/html5/thumbnails/54.jpg)
Delayed Speech
• Failure of speech to develop at the expected age – Some children with delayed speech develop
little or no expressive speech beyond vocalizations that are not interpretable as conventional language
– Other children with delayed speech can speak a little, but their proficiency is limited for their age and they mainly use nouns without qualifying or auxiliary words
![Page 55: Chapter 14](https://reader035.vdocuments.site/reader035/viewer/2022070419/56815d3c550346895dcb41e9/html5/thumbnails/55.jpg)
Etiology of Speech Delays
• may stem from experience deprivation, • may be the result of sensory deprivation
from an anatomical defect such as a hearing loss
• neurological problems (e.g., cerebral palsy)• serious emotional disturbances such as
childhood schizophrenia and autism and less severe problems such as negativism
![Page 56: Chapter 14](https://reader035.vdocuments.site/reader035/viewer/2022070419/56815d3c550346895dcb41e9/html5/thumbnails/56.jpg)
Negativism
• When children are developing speech, great pressure is being exerted on them by their parents to learn many other skills as well
• Demands exceed some children’s tolerance level, and they may be unable to perform as expected
• Certain children respond negatively to such a situation by refusing to perform
![Page 57: Chapter 14](https://reader035.vdocuments.site/reader035/viewer/2022070419/56815d3c550346895dcb41e9/html5/thumbnails/57.jpg)
• If form of rebellion, the reward contingencies in the environment must be altered
• may also be necessary to alter behavior patterns that are only indirectly related to the speech delay
![Page 58: Chapter 14](https://reader035.vdocuments.site/reader035/viewer/2022070419/56815d3c550346895dcb41e9/html5/thumbnails/58.jpg)
Experience Deprivation
• Environmental contingencies must exist in a configuration that will permit and promote children’s learning to speak
• Some households that do not promote language acquisition, and significantly delayed child speech may result
– child does not have much exposure to modeling of speech and perhaps receives little reinforcement for speaking and vocalizing
![Page 59: Chapter 14](https://reader035.vdocuments.site/reader035/viewer/2022070419/56815d3c550346895dcb41e9/html5/thumbnails/59.jpg)
Other Circumstances
• A child with normal hearing capacity is born to deaf parents
• May also occur in homes where there is a great deal of verbalization and noise occurring in a very confused and unsystematic fashion
![Page 60: Chapter 14](https://reader035.vdocuments.site/reader035/viewer/2022070419/56815d3c550346895dcb41e9/html5/thumbnails/60.jpg)
Treatment of Speech Delays
• Speech delay caused by experience deprivation can be treated by using fundamental principles of learning
![Page 61: Chapter 14](https://reader035.vdocuments.site/reader035/viewer/2022070419/56815d3c550346895dcb41e9/html5/thumbnails/61.jpg)
Phonological Disorders
• Previously classified as articulation disorders
• Most frequently occurring category of all speech disorders according to DSM-IV-TR
