E N D
The research area • Interdisciplinary • Pediatrics, Psychologists, Psychiatrists, other mental/health care disciplines • Relatively new field (since mid-1980) • Term ‘trauma’ can create problems for understanding across disciplines = physical injury (e.g. traumatic brain injury) for medical practitioner
Terms and definitions • Medical traumatic stress • Pediatric traumatic stress • Medical trauma
Pediatric Medical Traumatic Stress (PMTS) • “a set of psychological and physiological responses of children and their families to pain, injury, serious illness, medical procedures, and invasive or frightening treatment experiences” (NCTSN, 2009) • Similar and related to ASD and PTSD • PTSS = continuum of key symptoms • E.g., Arousal, re-experiencing, avoidance
Illness and Injuries frequently studied • Cancer • Organ transplant • Burns • Motor vehicle/ road traffic accidents • Traumatic brain injury
Potentially Traumatic Medical Events (PTME) (Kazak et al., 2006) • Injury • Most common experience (1 in 4 children receive medical care each year) (National Safe Kids Campaign, 2004) • Other conditions, burns, sickle cell disease, diabetes, sever asthma • Painful procedures and frightening treatment experiences • Affect large groups • Cancer and other complications of other chronic and potentially dehabilitating conditions • From epidemiological perspective less common (but common in medical settings) • Unintentional injuries and neoplasms are most common cause of death in childhood (Arias et al., 2003)
Some Questions (Stuber et al, 2003) • Basic questions about diagnostic requirements • Symptoms cause real functional impairment or clinical important distress? • What number of symptoms, severity of symptoms, or level of impairment necessary (to be clinically significant) • Applied theoretical/practical questions • What constitutes the traumatic event in medical illness • Event differs for children and parents • Who develop and sustain symptoms • Similar symptoms to children exposed to other types of traumatic events
Prevalence of ASD and PTSD Debate about prevalence and suitability of PTSD framework
ASD vs. PTSD ASD PTSD A: (1) + (2) B: re-experiencing (1) C: Avoidance (3) D: Increased arousal (2) E: lasts for more than 1 mo F: clinically significant distress or impairment Duration and onset Duration: < 3 mo = acute, >3mo = chronic Onset: >6mo = delayed • A: (1) traumatic event, and (2) subjective response • B: dissociative symptoms (3) • C: persistent re-experiencing (1) • D: marked avoidance (?) • E: marked anxiety or increased arousal (?) • F: clinically significant distress or impairment • G: Lasts for min. 2 days, max. 4 weeks, within 4 weeks of event • H: not due to effects of substance (drug) or medical conditions
Illness: Childhood Cancer • Bone marrow transplant (cancer) (Stuber et al., 1991) • All children increased PTSD symptoms even 12 months post • Cancer vs. other traumas (Pelcovitz et al., 1998) • 35% of adolescent cancer met PTSD criteria vs. ‘only’ 7% physically abused (life-time PTSD) • 17% cancer vs. 11% abuse (current PTSD)
Illness: Childhood Cancer • Disease-free childhood cancer survivors at end of treatment (Barakat et al., 1997; Kazak et al., 1997) • No sign. difference between Cancer survivors and controls • Cancer: 2.6% severe, 12.1% moderate symptoms • Controls: 3.4% sever, 12.3% moderate • Young adult survivors (Hobbie et al., 2000; Rourke et al., 1999) • 20.5% met DSM-IV criteria (at some point after end of treatment)
Illness: Organ Transplant • Adolescent heart, liver, kidney transplant recipients (1 year post-transplant) (Mintzer et al, 2005) • 16% met criteria of PTSD, another 14.4% met 2/3 symptom clusters • Children in pediatric ICU (intensive care unit) vs. children in general pediatric wards (after discharged) (Rees et al., 2004) • 21% of ICU, none in general ward
Other Illnesses • Adolescents with life-threatening asthma (Kean et al., 2006) • 20% met PTSD criteria • Children undergoing surgery for congenital heart disease (CHD) (Toren & Horesh, 2007) • CHD most common birth defect (1/125), twice as many as all cancers combined • 30% met PTSD criteria
Injury (PTSD) • Children with motor vehicle/ traffic injury (see O’Donnell et al, 2003; Saxe et al., 2003) • PTSD assessed 1-6 mo post-injury range from 17.5% to 42% • 12 mo. post-injury 2% to 36% • Children with burns (e.g., Stoddard et al., 1989) • 50% PTSD symptoms • 6.7% met DSM-III PTSD criteria (8.9 years post-burn) • No studies using DSM-IV
Injury (ASD) • Diagnosis widely criticized (Bryant & Harvey, 1997) • Only few studies, mostly physical injuries • 14-16% MVA (Bryant & Harvey, 1998; Harvey & Bryant, 1999) • 12% burns (Harvey & Bryant, 1999) • Other injuries 6-16% (Mellman et al., 2001; Fuglsang et al., 2002)
Traumatic brain injury (TBI) • TBI = insult to the brain typically resulting in loss of consciousness • Discussion: Do you think PTSD is possible in TBI?
Traumatic brain injury (TBI) • Argued that if experiences not encoded one cannot posses trauma-related memories (Mayou et al., 1993) • Empirical Review (Bryant, 2001) • Mild TBI: 24-33% met PTSD criteria • Sever TBI: 27% PTSD • Childhood PTSD: 4-14%, but 68% at least one PTSD symptomn
Debate about prevalence and suitability of PTSD framework • Variations most likely due to methodological issues (O’Donnell et al., 2003) • Physical injury (symptoms due to organic pathology) • Role of traumatic brain injury (e.g., amnesia) • Influence of subsequent and prior traumatization • Symptoms may be caused by medication (i.e. Narcotic analgesia) • Timing of assessment • Sample size and selection • Role of litigation (compensation)
Direct comparison of different conditions • Walker et al (1999) • Transplant vs. chronic illness and routine surgery • PTS sign. greater in transplant group • LTX=20.83, CHA=12.50, ENT=4.77 (mean CPTS-RI) • Landolt et al (2003) • Diabetes, cancer and accident-related injury • Accident-related injury associated with higher PTSS scores • 14.6% accidents, 10% cancer, 5.4% diabetes (moderate to sever)
Comparison with other types of traumatic events • Stoppelbein et al., 2006 • Cancer vs. parental bereavement (traumatic?) • Lower levels in cancer (m=24.03) than in bereaved children (m=37.15) (CPTS-RI score)
Comparison with health peers • Gerhardt et al., 2007 • No sign. Difference: 3% cancer past PTSD vs. 6% controls (?), 20% cancer vs. 13% control at leats one PTSS • Brown et al., 2003 • PTSD higher in cancer than in comparions • Schwartz & Drotar, 2006 • PTSD more likely in cancer, no difference on sub-clinical PTSD symptoms
Conclusion about prevalence • PTSD is not a universal side-effect of childhood medical illness or injury • Expect perhaps acute burns • However, PTSS in majority of these children • Move beyond debating prevalence (Manne, 2009)
Adopting a broader perspective(Manne, 2009) • cross-situation perspective • Unique and common characteristics of childhood illness and injury • Cognitive, psychological, biological characteristics of child, parents, family’s social context • Sub-clinical PTSS syndromes, other psychological problems • Quality of life
Other relevant clinical conditions • Co-morbitity in PTSD is the norm • 80-85% of individuals with PTSD meet criteria for another psychiatric condition (in large community samples) (Bradley et al., 2000; Creamer et al., 2001) • Depression: 60% at discharge to 9% at 12 mo post) (Schnyder et al., 2001; Shalev et al., 1998; Holbrook et al., 1998) • Anxiety disorders (other than PTSD) and substance use (Blanchard et al., 1995; Mayou et al., 2001)
Other psychological problems: Beyond disorders • Quality of life (QOL) • Far reaching consequences for quality of life • Burn survivors (Landolt et al., 2007) • Overall QOL impaired in children with PTSD • PTSD severity associated with impaired physical, cognitive and emotional dimensions of QOL • Limited physical (e.g. more bodily complaints) and emotion functioning (e.g. more feelings of sadness)
Factors predict PTSD and PTSS • Child characteristics • Persistent, unmanaged pain (Saxe et al., 2001; Stoddard et al., 2006) • Medical complications (Mintzer et al., 2005) • Sustained bodily disfigurement (Rusch et al., 2000) • Cognitive impairment (Vasa et al., 2004) • Life-threatening episode (e.g., asthma episode) (Kean et al., 2006) • Recurrence of illness (Jurbergs et al., 2007)
Cognitive characteristics of child • Current perception of threat posed by illness injury • Perceive the illness as life-threatening (Barakat et al., 1997; Rourke et al, 2007) • Perceive treatment as more intense (Barakat et al., 1997; Rourke et al, 2007) • Perceive higher risk for recurrence (Stoppelbein et al., 2006) • Perceive that medical complications are more sever (Copeland et al., 2007)
Psychological characteristics • Pre-trauma psychological problems • Trait anxiety (Ozono et al., 2007) • Anxiety disorder (Muris et al., 2003) • Emotional response during illness or immediately post-injury • Significant distress and/or traumatic symptomatology in children (Bryant et al., 2007; DiGallo et al., 1997) and parents (Manne et al., 2004; Ribi et al., in press)
Biological and genetic factors • Physiological arousal indices (e.g., increased heart rate) (De Young et al., 2007; Stoddard et al., 2006) • High epinephrine and cortisol levels (Delahanty et al., 2005; Glover & Poland, 2002) • Genes/genetic polymorphism involved in dopamine and serotonin regulation (Koene et al., 2005; Lu et al, in press)
Factors predict PTSD and PTSS • Family contextual factors • Perceived social support from family members (protective) (Kazak et al., 1999) • Family conflict (risk) (Manne et al., 2002)
Resilience and Posttraumatic growth • In acute phase majority shows symptoms • Long-term majority seems to be resilient • Posttraumatic Growth in a considerable proportion (e.g. Barakat et al., 2006)
Developmental considerations • Developmental difference may alter type of response (Widows et al., 2000) • Medical illness and injury at different developmental stages may result in different psychopathology (Stuber et al., 1996) • Depends on children’s understanding of illness • Some PTSD symptoms may not appear until adolescent (Hobbie et al., 2000; Rourke et al., 1999)
Scheeringa et al. (1995) suggest • Requirement of effortful avoidance and memory gaps to be deleted • Behavioral symptoms, such as play re-enactment, separation anxiety, nightmares, and aggression to be added
Children’s understanding of illness • Depends on cognitive development (Salmon & Bryant, 2002) • Theory of mind? • awareness of own and others mental states such as beliefs, desire, intentions and emotions • Seems highly relevant! • Especially relevant = understanding of symptoms (and control of symptoms) • Medical symptoms? • Psychological symptoms (e.g. intrusive thoughts)
Developmental aspects • Landolt et al. (2009) report poorer physical, motor, cognitive + emotional functioning in children with PTSD symptoms • Is it possible that PTSD and PTSS impede development?
