  1. 13 Health-Related and Substance-UseDisorders

  2. History • Ancient Greek philosophers believed disease was caused by an imbalance in the body’s basic elements • Medieval period: belief that mental and physical illnesses resulted from demonic possession • 19th century: Charcot and Freud studied the role of the mind in physical symptoms

  3. History (cont’d.) • 20th Century • 1968: The Society of Pediatric Psychology was established to connect psychology and pediatrics • 1976: SPP established the Journal of Pediatric Psychology • Broadened the research and theory on physical outcomes of child health disorders to encompass: the psychosocial effects of illness; and the interplay between psychosocial effects and illness

  4. Sleep Disorders • Sleep is the primary activity of the brain during the early years of development • A bidirectional relationship exists between sleep problems and psychological issues • Sleep disorders can: • Cause other psychological problems • Result from other disorders • Mimic or worsen symptoms of major disorders

  5. The Regulatory Functions of Sleep • Sleep is essential for brain development • Sleep deprivation impairs functioning of the prefrontal cortex • Leading to decreased concentration and diminished ability to inhibit or control basic drives, impulses, and emotions • Sleep produces an “uncoupling” of neurobehavioral systems • Allowing for retuning of CNS components

  6. Maturational Changes • Sleep patterns, needs, and problems change over the course of maturation • Infants and toddlers ► more night-waking problems • Preschoolers ► more falling-asleep problems • Younger school-aged children ► more going-to-bed problems • Adolescents have increased need for sleep, but are often sleep deprived

  7. Features of Sleep Disorders • Primary sleep disorders are the result of: • Abnormalities in the body’s ability to regulate sleep-wake mechanisms • The timing of sleep

  8. Features of Sleep Disorders (cont'd.) • Dyssomnias: disorders of initiating or maintaining sleep • Are characterized by difficulty getting enough sleep, not sleeping when one wants to, and not feeling refreshed from sleep • Involve disruptions in the sleep process • May resolve themselves as the child matures • Are quite common in childhood, with the exception of narcolepsy

  9. Dyssomnias

  10. Parasomnias • Disorders in which behavioral or physiological events intrude on ongoing sleep • Involve physiological or cognitive arousal at inappropriate times during sleep-wake cycle • Complaints of unusual behaviors while asleep • Common afflictions of early to mid-childhood • Include nightmares (REM parasomnias) and sleep terrors and sleepwalking (often referred to as arousal parasomnias)

  11. Parasomnias (cont'd.)

  12. Treatment • Behavioral interventions • Identify suspected causes of disrupted sleep • Behavioral interventions for circadian rhythm disorders can be effective when adolescent and family are highly motivated • Goals of behavioral intervention is to: • Eliminate sleep deprivation • Restore a more normal sleep and wake routine

  13. Treatment (cont’d.) • Prolonged treatment of parasomnias is usually not necessary • Treatment of nightmares • Provide comfort at the time of the occurrence and attempt to reduce daytime stressors • Parents of sleepwalkers should take precautions to avoid chances of the child being injured • Brief afternoon naps may be beneficial

  14. Elimination Disorders • Elimination problems can turn into distressing and chronic difficulties • Can affect participation in education and social activities • Two elimination problems occurring during childhood and adolescence • Enuresis • Encopresis • Children eventually outgrow eliminating disorders

  15. Enuresis • Involuntary discharge of urine during day or night • Three subtypes • Nocturnal only - most common; wetting occurs only during sleep at night • Diurnal only - passage of urine during waking hours, more common in females • May be associated with social anxiety or preoccupation with a school event • Combination of nocturnal and diurnal

  16. Prevalence and Course • Nocturnal enuresis 4-13% for children under age 10 • By age 10 - affects 3% of males and 2% of females • By late adolescence - declines to 1% of males and less than 1% of females • Diurnal enuresis affects 3% of 6-year-olds • Both forms - more common among less educated, lower SES, and institutionalized children

  17. Causes and Treatment • Causes include deficiency of antidiuretic hormone (ADH), immature signaling mechanism, and genetics • Treatments • Standard behavioral training methods • Medications - desmopressin (synthetic ADH); • Psychological interventions (especially urine alarm) are more effective than medications or waiting for the child to grow out of the problem

  18. Encopresis • The passage of feces in inappropriate places • Two DSM-5 subtypes: with or without constipation and overflow incontinence • Prevalence and course • 1% of 5-year olds; more common in boys • Primary encopresis: child has reached age 4 without establishing fecal continence) • Secondary encopresis: current episode preceded by period of continence

  19. Causes and Treatment • Causes include : • Avoiding, suppressing, and not recognizing signs when it is time for a bowel movement • Abnormal defecation dynamics that, combined with avoidance, increases risk for chronic constipation ► encopresis develops • Treatment includes combined medical and behavioral interventions

  20. Chronic Illness • A chronic illness is one that: • Persists for more than three months in a given year or requires a period of continuous hospitalization for more than one month • 10-20% of youths under age 18 will experience one or more chronic health conditions • Approximately 5% of these children suffer from a disease so severe that it interferes with daily activities

  21. Chronic Illness (cont’d.) • DSM-5 categories (somatoform disorders and psychological factors affecting physical condition) have limited applicability to pediatric populations • Somatoform disorders (e.g., somatization, hypochondriasis, and pain disorders) involve physical symptoms that resemble or suggest a medical condition but lack organic or physiological evidence

  22. Normal Variations in Children’s Health • Children have a good concept of pain and how to express it • Children often express fears, dislikes, and avoidance through somatic complaints • Girls report more symptoms of pain and anxiety

  23. Normal Variations in Children’s Health (cont’d.) • Chronic illness viewed as a form of major stress that requires adaptation • Helps researchers identify factors promoting successful adaptation to chronic illnesses • Asthma is the most common chronic illness in childhood

  24. Normal Variations in Children’s Health (cont’d.) • Social class and ethnicity do not influence who is affected by chronic illness • A connection exists between SES, ethnicity, and survival rates among children and adults • Particularly those with cancer

  25. Incidence Rates of Selected Chronic Illnesses

  26. Diabetes Mellitus • Insulin-dependent diabetes mellitus is a lifelong metabolic disorder • The body is unable to metabolize carbohydrates as a result of inadequate pancreatic release of insulin • Treatment regimen includes insulin injections, diet, and exercise • Metabolic control is intrusive and can be especially difficult during adolescence

  27. Diabetes Mellitus (cont’d.) • No gender differences • Rates of the disease are increasing • Today’s children have a one in three chance of being diagnosed with diabetes • Behavioral strategies: • Help promote regimen adherence, metabolic control, and family adaptation • Reinforce symptom reduction or medication use, and self-control methods

  28. Childhood Cancer • In comparison to adults, onset in children is more sudden and the disease is often at a more advanced stage when first diagnosed • Most common form is acute lymphoblastic leukemia (ALL)

  29. Childhood Cancer (cont'd.) • Long-term complications from recurrent malignancy, growth retardation, neuropsychological deficits, cataracts, and infertility continue to pose a risk to survival and quality of life • Approximately 80% of pediatric cancer patients survive • 50% will have serious physical or mental illness as adults and will require long-term care

  30. Development and Course • Children with chronic illnesses are more likely to suffer emotional and behavioral adjustment problems • Children with chronic illness accompanied by disability are at greatest risk • Most children adapt successfully to their illness and show considerable resilience

  31. Development and Course (cont’d.) • Effect on family members • The child’s illness may result in family cohesion and support or in family disruption and crisis • Chronic illness may precipitate PTSD in family members • Perceived social support and parental adaptation are key • Siblings of children with a chronic illness experience heightened social and mental health problems

  32. Social Adjustment and School Performance • Children with more severe, disruptive illnesses suffer primarily in social adjustment • Maladjustment may be expressed by displaying submissive behavior with peers and engaging in less social activity • Social adjustment problems are linked to CNS illnesses because they impact cognitive abilities such as social judgment

  33. The Transactional Stress and Coping Model • Adaptation to chronic illness is influenced by the nature of the illness, and also by personal and family resources • Child and family processes mediate the illness-outcome relationship • Psychological mediators include parental adjustment, child adjustment, and their interrelationship

  34. Intervention • Psychosocial interventions • Empowering families • Support groups and educational programs • Treatment-related activities based on needs of the family • Helping children cope • Providing information and training in coping skills

  35. Adolescent Substance Use Disorders (SUDs) • SUDs in adolescence include substance dependence and substance abuse • Criteria for substance abuse involve one or more harmful and repeated negative consequences of substance use over the last 12 months • Diagnosis of substance abuse is not given if the individual meets criteria for substance dependence

  36. Adolescent Substance Use Disorders (cont’d.)

  37. Adolescent Substance Use Disorders (cont’d.)

  38. Prevalence and Course • Alcohol is the most prevalent substance used and abused by adolescents • Adolescent cigarette smoking has been declining • Daily marijuana use has increased • Use of other illicit drugs such as MDMA, opiates, cocaine, and crack has increased • Estimated 12% of American adolescents • Meet the criteria for substance abuse or dependence

  39. Trends in Annual Prevalence Use

  40. Age of Onset • Some amount of substance use during adolescence is normative behavior • Critical risk factor is age of first use • The odds of developing alcohol dependence decreases by 9% for each year that onset of drinking is delayed • Alcohol use before age 14 is a strong predictor of subsequent alcohol abuse or dependence

  41. Sex and Ethnicity • Sex differences in lifetime prevalence rates are converging due to increased substance use among girls • African American youth have substantially lower usage rates than whites • Hispanics have the highest rate of lifetime usage for powder cocaine, crack cocaine, heroin, and methamphetamines

  42. Illicit Drug Use Among Persons 12 or Older

  43. Course • Rates typically peak around late adolescence then decline during young adulthood • Alcohol use influences involvement in other high-risk behaviors, especially unsafe sexual activity, smoking, and drinking and driving • Girls who report dating aggression are five times more likely to use alcohol than girls in nonviolent relationships; boys are two-and-one-half times more likely

  44. Associated Characteristics • Using more than one drug simultaneously • Poor academic achievement, higher rates of academic failure, and higher rates of delinquency • More parental conflict, • Disruption of neurodevelopmental processes • High comorbidity with ADHD and conduct problems

  45. Personality Characteristics • Increased sensation seeking preference for novel, complex, and ambiguous stimuli • Positive attitudes about substance abuse and having friends with similar attitudes • Perceiving oneself to be physically older than same-age peers and striving for adult social roles • School disconnectedness

  46. Other Causes • Family functioning • Lack of parental involvement • Lower trust between adolescent females and their parents • Peers and culture • Association with deviant and substance-using peers • False consensus (“everyone’s doing it”) • Substance use glamorized by peer culture

  47. Treatment and Prevention • Family-based approaches that seek to: • Modify negative interactions between family members, improve communication, and develop effective problem-solving skills to address areas of conflict • Motivational interviewing (MI) • A patient-centered and directive approach • Addresses ambivalence and discrepancies between a person’s current values and behaviors and their future goals

  48. Treatment and Prevention (cont’d.) • Adolescents with more severe levels of abuse, unstable living conditions, or comorbid psychopathology require an inpatient or residential setting • Effective approaches address multiple influences (peer, family, school, and community) on the individual
