Topical Review: Medical Trauma During Early Childhood.

OBJECTIVE: Early childhood is a high-risk period for exposure to traumatic medical events due to injury/illness. It is also one of the most important and vulnerable periods due to rapid development in neurobiological systems, attachment relationships, cognitive and linguistic capacities, and emotion regulation. The aim of this topical review is to evaluate empirical literature on the psychological impact of medical trauma during early childhood (0-6 years) to inform models of clinical care for assessing, preventing, and treating traumatic stress following injury/illness. METHODS: Topical review of empirical and theoretical literature on pediatric medical traumatic stress (PMTS) during early childhood. RESULTS: There are important developmental factors that influence how infants and young children perceive and respond to medical events. The emerging literature indicates that up to 30% of young children experience PMTS within the first month of an acute illness/injury and between 3% and 10% develop posttraumatic stress disorder. However, significant knowledge gaps remain in our understanding of psychological outcomes for infants and young children, identification of risk-factors and availability of evidence-based interventions for medical trauma following illness. CONCLUSIONS: This topical review on medical trauma during early childhood provides: (a) definitions of key medical trauma terminology, (b) discussion of important developmental considerations, (c) summary of the empirical literature on psychological outcomes, risk factors, and interventions, (d) introduction to a stepped-model-of-care framework to guide clinical practice, and (e) summary of limitations and directions for future research.

Accuracy of delirium assessments in critically ill children: A prospective, observational study during routine care.

OBJECTIVES: The objectives of this study was to explore the accuracy of the Cornell Assessment for Pediatric Delirium (CAP-D), Pediatric Confusion Assessment Method for the Intensive Care Unit (pCAM-ICU), and Preschool Confusion Assessment Method for the Intensive Care Unit (psCAM-ICU) when implemented in routine care as delirium screening tools, and to assess patient characteristics and clinical variables that may affect their validity. DESIGN: This is a prospective observational study. SETTING: The study was conducted in a 36-bed, mixed paediatric intensive care unit (PICU) at an Australian tertiary hospital. PATIENTS: The study included critically ill children developmentally aged 6 months to 17 years, with a PICU length of stay >18 h. INTERVENTIONS: No interventions were provided in the study. MEASUREMENTS AND MAIN RESULTS: Patients were screened for delirium by their bedside nurse (CAP-D and pCAM-ICU/psCAM-ICU) once daily, for up to 5 d. Delirium status identified using screening instruments was compared with delirium diagnosis using the diagnostic criteria for delirium (Diagnostic and Statistical Manual of Mental Disorders, 5th Edition). In this sample, the CAP-D retained its high sensitivity (91.3%) and good specificity (75.2%), whereas the psCAM-ICU and pCAM-ICU had moderate sensitivity (58.8% and 75.0%, respectively) and excellent specificity (89.8% and 84.9%, respectively). There was moderate agreement between the CAP-D and the psCAM-ICU (κ = 0.52, p < .001) and good agreement between the CAP-D and the pCAM-ICU (κ = 0.80, p < .01). CONCLUSIONS: Although the CAP-D, psCAM-ICU, and pCAM-ICU all appear promising in their validation studies, when implemented in routine care, their performance can be variable. The CAP-D performed well in routine clinical practice, but follow-up diagnosis is required to confirm delirium. The psCAM-ICU and pCAM-ICU both provide valuable, objective assessments of delirium in critically ill children; however, further evaluation of their implementation in routine clinical practice is needed.

Development of an international data repository and research resource: the Prospective studies of Acute Child Trauma and Recovery (PACT/R) Data Archive.

Background: Studies that identify children after acute trauma and prospectively track risk/protective factors and trauma responses over time are resource-intensive; small sample sizes often limit power and generalizability. The Prospective studies of Acute Child Trauma and Recovery (PACT/R) Data Archive was created to facilitate more robust integrative cross-study data analyses. Objectives: To (a) describe creation of this research resource, including harmonization of key variables; (b) describe key study- and participant-level variables; and (c) examine retention to follow-up across studies. Methods: For the first 30 studies in the Archive, we described study-level (design factors, retention rates) and participant-level (demographic, event, traumatic stress) variables. We used Chi square or ANOVA to examine study- and participant-level variables potentially associated with retention. Results: These 30 prospective studies (N per study = 50 to 568; overall N = 5499) conducted by 15 research teams in 5 countries enrolled children exposed to injury (46%), disaster (24%), violence (13%), traffic accidents (10%), or other acute events. Participants were school-age or adolescent (97%), 60% were male, and approximately half were of minority ethnicity. Using harmonized data from 22 measures, 24% reported significant traumatic stress ≥1 month post-event. Other commonly assessed outcomes included depression (19 studies), internalizing/externalizing symptoms (19), and parent mental health (19). Studies involved 2 to 5 research assessments; 80% of participants were retained for ≥2 assessments. At the study level, greater retention was associated with more planned assessments. At the participant level, adolescents, minority youth, and those of lower socioeconomic status had lower retention rates. Conclusion: This project demonstrates the feasibility and value of bringing together traumatic stress research data and making it available for re-use. As an ongoing research resource, the Archive can promote 'FAIR' data practices and facilitate integrated analyses to advance understanding of child traumatic stress.

Antecedentes: Los estudios que identifican niños luego de la exposición a trauma agudo y realizan un seguimiento prospectivo para identificar factores protectores o de riesgo, y respuestas al trauma en el tiempo requieren una gran cantidad de recursos; el tamaño pequeño de las muestras frecuentemente limita su poder y generalización. El Banco de Información de los Estudios Prospectivos sobre Trauma Agudo y Recuperación en el Niño (PACT/R por sus siglas en inglés) se creó para facilitar un análisis de datos más robusto e integrativo entre los estudios.Objetivos: a) Describir la creación de este recurso de investigación, incluyendo la armonización de variables clave; b) describir las variables clave a nivel de estudios y de participantes; y c) evaluar la permanencia del seguimiento en los estudios.Métodos: Describimos las variables 'nivel de estudio' (diseño, factores, tasas de permanencia) y 'nivel de participantes' (demografía, evento, estrés traumático) en los 30 primeros estudios del Banco. Empleamos Chi cuadrado o ANOVA para evaluar los niveles de estudio y de participante potencialmente asociados con la permanencia.Resultados: Estos 30 estudios prospectivos (N por estudio = 50 a 568; total N = 5499) realizados por 15 grupos de investigación en 5 países reclutaron niños expuestos a lesión (46%), desastre (24), violencia (13%), accidentes de tránsito (10%) u otros eventos agudos. Los participantes estaban en edad escolar o en la adolescencia (97%), 60% eran varones y, aproximadamente la mitad pertenecían a una minoría étnica. Empleando la armonización de datos para 22 mediciones, el 24% reportó estrés traumático significativo mayor o igual a un mes luego del evento. Otros desenlaces comúnmente evaluados incluyeron a la depresión (19 estudios), síntomas internalizantes y externalizantes (19), y salud mental de los padres (19). Los estudios incluyeron entre 2 y 5 evaluaciones de investigación; 80% de los participantes fueron mantenidos para dos o más evaluaciones. En el nivel de estudio, una mayor permanencia se asoció a un mayor número de evaluaciones planificadas. En el nivel de participantes, los adolescentes, los jóvenes pertenecientes a minorías, y aquellos en niveles socioeconómicos más bajos presentaron menores tasas de permanencia.Conclusión: Este proyecto demuestra la viabilidad y el valour de integrar la información sobre la investigación en estrés traumático y hacerla disponible para ser reutilizada. Como recurso de investigación en curso, el Banco puede promover el uso de prácticas de información 'FAIR' y facilitar el análisis integrado para generar progreso en la comprensión del estrés traumático infantil.

The Course of Posttraumatic Stress in Children: Examination of Symptom Trajectories and Predictive Factors Following Admission to Pediatric Intensive Care.

OBJECTIVES: This study investigated trauma symptom trajectories of children 2-16 years old following admission to pediatric intensive care and identified factors that predicted a child's trauma symptom trajectory. DESIGN: Prospective longitudinal design. SETTING: Two tertiary care PICUs in Brisbane, Qld, Australia. PATIENTS: Children 2-16 years old admitted to PICU for longer than 8 hours. MEASUREMENTS MAIN RESULTS: Maternal reported child posttraumatic stress symptoms (n = 272) on the Trauma Symptom Checklist for Young Children were used to assess posttraumatic stress symptoms up to 12 months post admission. Semiparametric group-based trajectory analyses were completed to identify patterns over time. Age, gender, length of stay, premorbid functioning, maternal perceived threat to life, and maternal acute distress were assessed as potential risk factors. Three likely trajectory groups were identified. The majority of children were resilient (83.8%); however, a significant minority experienced chronic symptoms (12.9%) or elevated stress symptoms which resolved quickly (3.3%). After controlling for other variables, maternal report of premorbid internalizing behavior significantly predicted both chronic (odds ratio, 6.3) and recovery (odds ratio, 38.0) trajectories. Maternal acute distress significantly predicted child chronic symptom trajectories (odds ratio, 5.2). CONCLUSIONS: Children with elevated trauma symptoms postintensive care need timely and effective intervention. The majority of children with high levels of acute symptoms will continue to have chronic, ongoing posttraumatic stress symptoms. In addition, acute maternal distress and preexisting internalizing child behavior predict ongoing psychologic distress after discharge from the PICU. Screening in the acute period post-PICU admission may identify children likely to experience ongoing chronic posttraumatic distress symptoms and enable targeted treatment of children at risk. This is the first study to examine symptom trajectories in children following pediatric intensive care admission and includes a sample of very young children.

Preventive intervention for trauma reactions in young injured children: results of a multi-site randomised controlled trial.

BACKGROUND: Young children are at particular risk for injury. Ten per cent to twenty-five per cent develop posttraumatic stress disorder (PTSD). However, no empirically supported preventive interventions exist. Therefore, this study evaluated the efficacy of a standardised targeted preventive intervention for PTSD in young injured children. METHODS: Injured children (1-6 years) were enrolled in a multi-site parallel-group superiority prospective randomised controlled trial (RCT) in Australia and Switzerland. Screening for PTSD risk occurred 6-8 days postaccident. Parents of children who screened 'high-risk' were randomised to a 2-session CBT-based intervention or treatment-as-usual (TAU). Primary outcomes were PTSD symptom (PTSS) severity, and secondary outcomes were PTSD diagnosis, functional impairment and behavioural difficulties at 3 and 6 months postinjury using blinded assessments. Trials were registered with the Australian New Zealand Clinical Trials Registry (ACTRN12614000325606) and ClinicalTrials.gov (NCT02088814). Trial status is complete. RESULTS: One hundred and thirty-three children screened 'high-risk' were assigned to intervention (n = 62) or TAU (n = 71). Multilevel intention-to-treat analyses revealed a significant intervention effect on PTSS severity over time (b = 60.06, 95% CI: 21.30-98.56). At 3 months, intervention children (M = 11.02, SD = 10.42, range 0-47) showed an accelerated reduction in PTSS severity scores compared to control children (M = 17.30, SD = 13.94, range 0-52; mean difference -6.97, 95% CI: -14.02 to 0.08, p adj. = .055, d = 0.51). On secondary outcomes, multilevel analyses revealed significant treatment effects for PTSD diagnosis, functional impairment and behavioural difficulties. CONCLUSIONS: This multi-site RCT provides promising preliminary evidence for the efficacy of a targeted preventive intervention for accelerating recovery from PTSS in young injured children. This has important clinical implications for the psychological support provided to young children and parents during the acute period following a single-event trauma.

Cognitive/affective factors are associated with children's acute posttraumatic stress following pediatric intensive care.

This study aimed to explore children's experiences and memories of the pediatric intensive care unit (PICU) and identify the relative importance of premorbid, trauma, and cognitive/affective variables associated with acute posttraumatic stress symptoms (PTSS). Participants were 95 children aged 6-16 years admitted to the PICU and their parents. Children completed questionnaires and an interview assessing PTSS, peritrauma affect, and their memory of the admission 3 weeks following discharge. Medical data were extracted from patient charts. Premorbid and demographic data were provided by parent questionnaire. Most children remembered some aspects of their admission. Younger age, admission for traumatic injury (rather than non-injury-related reasons), and cognitive/affective factors including confusion, peritrauma panic, and sensory memory quality were associated with acute PTSS. Age and traumatic injury accounted for 18% of the variance in PTSS (p < .01). The addition of cognitive/affective variables increased the explained variance to 38% (p < .001). Child age did not moderate the effect of cognitive/affective variables on PTSS. This study demonstrates that objective indicators of disease severity do not adequately explain the high prevalence of PTSS in children following PICU admission. It also suggests that subjective, cognitive factors such as the way children process and remember a PICU admission are very important in the onset of PTSS.

Large-Scale Dissemination of Internet-Based Cognitive Behavioral Therapy for Youth Anxiety: Feasibility and Acceptability Study.

BACKGROUND: Internet-based cognitive behavioral therapy (iCBT) for child and adolescent anxiety has demonstrated efficacy in randomized controlled trials, but it has not yet been examined when disseminated as a public health intervention. If effective, iCBT programs could be a promising first-step, low-intensity intervention that can be easily accessed by young people. OBJECTIVE: The objective of our study was to examine the feasibility and acceptability of a publicly available online, self-help iCBT program (BRAVE Self-Help) through exploration of program adherence, satisfaction, and changes in anxiety. METHODS: This study was an open trial involving the analysis of data collected from 4425 children and adolescents aged 7-17 years who presented with elevated anxiety at registration (baseline) for the iCBT program that was delivered through an open-access portal with no professional support. We assessed the program satisfaction via a satisfaction scale and measured adherence via the number of completed sessions. In addition, anxiety severity was assessed via scores on the Children's Anxiety Scale, 8-item (CAS-8) at four time points: baseline, Session 4, Session 7, and Session 10. RESULTS: Participants reported moderate satisfaction with the program and 30% completed three or more sessions. Statistically significant reductions in anxiety were evident across all time points for both children and adolescents. For users who completed six or more sessions, there was an average 4-point improvement in CAS-8 scores (Cohen d=0.87, children; Cohen d=0.81, adolescents), indicating a moderate to large effect size. Among participants who completed nine sessions, 57.7% (94/163) achieved recovery into nonelevated levels of anxiety and 54.6% (89/163) achieved statistically reliable reductions in anxiety. CONCLUSIONS: Participant feedback was positive, and the program was acceptable to most young people. Furthermore, significant and meaningful reductions in anxiety symptoms were achieved by many children and adolescents participating in this completely open-access and self-directed iCBT program. Our results suggest that online self-help CBT may offer a feasible and acceptable first step for service delivery to children and adolescents with anxiety.

Delirium in the Critically Ill Child: Assessment and Sequelae.

Delirium is a common and serious neuropsychiatric complication in critically ill patients of all ages. In the context of critical illness, delirium may emerge as a result of a cascade of underlying pathophysiologic mechanisms and signals organ failure of the brain. Awareness of the clinical importance of delirium in adults is growing as emerging research demonstrates that delirium represents a serious medical problem with significant sequelae. However, our understanding of delirium in children lags significantly behind the adult literature. In particular, our knowledge of how to assess delirium is complicated by challenges in recognizing symptoms of delirium in pediatric patients especially in critical and intensive care settings, and our understanding of its impact on acute and long-term functioning remains in its infancy. This paper focuses on (a) the challenges associated with assessing delirium in critically ill children, (b) the current literature on the outcomes of delirium including morbidity following discharge from PICU, and care-giver well-being, and (c) the importance of assessment in determining impact of delirium on outcome. Current evidence suggests that delirium is a diagnostic challenge for clinicians and may play a detrimental role in a child's recovery after discharge from the pediatric intensive care unit (PICU). Recommendations are proposed for how our knowledge and assessment of delirium in children could be improved.

Predictors of non-return to work 2 years post-injury in road traffic crash survivors: Results from the UQ SuPPORT study.

PURPOSE: Individuals who have sustained an injury from a road traffic crash (RTC) are at increased risk for long lasting health problems and non-return to work (NRTW). Determining the predictors of NRTW is necessary to develop screening tools to identify at-risk individuals and to provide early targeted intervention for successful return to work (RTW). The aim of this study was to identify factors that can predict which individuals will not RTW following minor or moderate injuries sustained from a RTC. METHOD: Participants were 194 claimants (63.4% female) within a common-law "fault-based" system from the UQ SuPPORT cohort who were working prior to their RTC. Participants were assessed at 6 months on a variety of physical and mental health measures and RTW status was determined at 2 years post-RTC. RTW rate was 78.4%. RESULTS: Univariate predictors of NRTW included being the driver or passenger, having a prior psychiatric diagnosis, high disability level, low mental or physical quality of life, predicted non-recovery, high pain, low function, high expectations of pain persistency, low expectations about RTW, having a psychiatric diagnosis, elevated depression or anxiety. The final multivariable logistic regression model included only two variables: disability level and expectations about RTW. Seventy-five percent of individuals who will not RTW by 2 years can be identified accurately at an early stage, using only these two predictors. CONCLUSION: The results are promising, because they suggest that having information about two factors, which are easily obtainable, can predict with accuracy those who will require additional support to facilitate RTW.

Generic versus disorder specific cognitive behavior therapy for social anxiety disorder in youth: A randomized controlled trial using internet delivery.

The study examined whether the efficacy of cognitive behavioral treatment for Social Anxiety Disorder for children and adolescents is increased if intervention addresses specific cognitive and behavioral factors linked to the development and maintenance of SAD in young people, over and above the traditional generic CBT approach. Participants were 125 youth, aged 8-17 years, with a primary diagnosis of SAD, who were randomly assigned to generic CBT (CBT-GEN), social anxiety specific CBT (CBT-SAD) or a wait list control (WLC). Intervention was delivered using a therapist-supported online program. After 12-weeks, participants who received treatment (CBT-SAD or CBT-GEN) showed significantly greater reduction in social anxiety and post-event processing, and greater improvement in global functioning than the WLC but there was no significant difference between CBT-SAD and CBT-GEN on any outcome variable at 12-weeks or 6-month follow-up. Despite significant reductions in anxiety, the majority in both treatment conditions continued to meet diagnostic criteria for SAD at 6-month follow-up. Decreases in social anxiety were associated with decreases in post-event processing. Future research should continue to investigate disorder-specific interventions for SAD in young people, drawing on evidence regarding causal or maintaining factors, in order to enhance treatment outcomes for this debilitating condition.

Coping with Accident Reactions (CARE) early intervention programme for preventing traumatic stress reactions in young injured children: study protocol for two randomised controlled trials.

BACKGROUND: Accidental injury represents the most common type of traumatic event experienced by children under the age of 6 years. Around 10-30 % of young injured children will go on to develop post-traumatic stress disorder (PTSD) and other co-morbid conditions. Parents of injured children are also at risk of PTSD, and this is associated with short- and long-term consequences for their children's physical and psychological recovery. Despite the significance of this problem, to date, the mental health needs of injured young children have been neglected. One reason for this is due to the uncertainty and considerable debate around how to best provide early psychological intervention to traumatised children and adults. To address these gaps, researchers and psychologists in Australia and Switzerland have developed the Coping with Accident Reactions (CARE) programme, which is a two-session early intervention designed to prevent persistent PTSD reactions in young injured children screened as 'at risk'. Two separate international studies are being conducted to evaluate the effectiveness and feasibility of this programme. METHODS/DESIGN: The study design for the two proposed studies will employ a randomised controlled trial design and children (aged 1-6 years) who are screened as at risk for PTSD 1 week after an unintentional injury, and their parents will be randomised to either (1) CARE intervention or (2) treatment as usual. Assessment will be completed at baseline (2 weeks) and 3 and 6 months post-injury. DISCUSSION: This international collaboration provides an excellent opportunity to test the benefit of screening and providing early intervention to young children in two different countries and settings. It is expected that outcomes from this research will lead to significant original contributions to the scientific evidence base and clinical treatment and recovery of very young injured children. TRIAL REGISTRATION: The Australian study was registered with the Australian New Zealand Clinical Trials Registry ( ACTRN12614000325606 ) on 26 March 2014. The Swiss study was registered with ClinicalTrials.gov ( NCT02088814 ) on 12 March 2014.

Early Maternal Reflective Functioning and Infant Emotional Regulation in a Preterm Infant Sample at 6 Months Corrected Age.

OBJECTIVE: This study investigated the influence of maternal reflective functioning (RF) on 6-month-old infants' emotional self-regulating abilities in preterm infant-mother dyads. METHODS: 25 preterm (gestational age 28-34.5 weeks) infants' affect, gaze toward mother, and self-soothing behaviors (thumb-sucking and playing with clothing) were measured during the still-face procedure at 6 months corrected age. Maternal RF was measured at 7-15 days post-delivery using the Parent Development Interview. RESULTS: Infants with high RF mothers showed the most negative affect during the still-face episode (M = 21.33s, SE = 5.44), whereas infants with low RF mothers showed the most negative affect in the reunion episode (M = 18.14s, SE = 3.69). Infants with high RF mothers showed significantly more self-soothing behaviors when distressed (Ms > 14.5s) than infants with low RF mothers (Ms < 1s), p's < .01. CONCLUSION: Maternal RF was associated with infants' self-regulating behavior, providing preliminary evidence for the regulatory role of maternal RF in preterm infants' emotion regulation capacity.

Physical Therapist-Delivered Pain Coping Skills Training and Exercise for Knee Osteoarthritis: Randomized Controlled Trial.

OBJECTIVE: To investigate whether a 12-week physical therapist-delivered combined pain coping skills training (PCST) and exercise (PCST/exercise) is more efficacious and cost effective than either treatment alone for knee osteoarthritis (OA). METHODS: This was an assessor-blinded, 3-arm randomized controlled trial in 222 people (73 PCST/exercise, 75 exercise, and 74 PCST) ages ≥50 years with knee OA. All participants received 10 treatments over 12 weeks plus a home program. PCST covered pain education and training in cognitive and behavioral pain coping skills, exercise comprised strengthening exercises, and PCST/exercise integrated both. Primary outcomes were self-reported average knee pain (visual analog scale, range 0-100 mm) and physical function (Western Ontario and McMaster Universities Osteoarthritis Index, range 0-68) at week 12. Secondary outcomes included other pain measures, global change, physical performance, psychological health, physical activity, quality of life, and cost effectiveness. Analyses were by intent-to-treat methodology with multiple imputation for missing data. RESULTS: A total of 201 participants (91%), 181 participants (82%), and 186 participants (84%) completed week 12, 32, and 52 measurements, respectively. At week 12, there were no significant between-group differences for reductions in pain comparing PCST/exercise versus exercise (mean difference 5.8 mm [95% confidence interval (95% CI) -1.4, 13.0]) and PCST/exercise versus PCST (6.7 mm [95% CI -0.6, 14.1]). Significantly greater improvements in function were found for PCST/exercise versus exercise (3.7 units [95% CI 0.4, 7.0]) and PCST/exercise versus PCST (7.9 units [95% CI 4.7, 11.2]). These differences persisted at weeks 32 (both) and 52 (PCST). Benefits favoring PCST/exercise were seen on several secondary outcomes. Cost effectiveness of PCST/exercise was not demonstrated. CONCLUSION: This model of care could improve access to psychological treatment and augment patient outcomes from exercise in knee OA, although it did not appear to be cost effective.

A Web-Based Early Intervention Can Prevent Long-Term PTS Reactions in Children With High Initial Distress Following Accidental Injury.

The present study explored the targeting of a preventative information provision intervention delivered to children following accidental injury by assessing the impact of initial traumatic distress on response to treatment. Analyses were based on baseline and 6-month outcome of child traumatic stress in a control (n = 28) and an intervention group (n = 31). Moderation of treatment outcome by initial levels of child traumatic stress was assessed through multiple hierarchical regression analyses. Results indicated the interaction between treatment provision and initial level of posttraumatic stress significantly predicted 6-month outcome (ß = -.42, p = .019). When initial distress was high, children in the control group demonstrated an increase in trauma symptoms, and had significantly higher trauma symptoms at follow-up than those in the treatment group (d = 0.94, p = .008). When initial distress was not elevated, no significant differences were noted between the groups. These results indicate that a preventative early intervention may be best targeted at children presenting with the specific risk factor of high initial distress.

A new method for assessing content validity in model-based creation and iteration of eHealth interventions.

BACKGROUND: The advent of eHealth interventions to address psychological concerns and health behaviors has created new opportunities, including the ability to optimize the effectiveness of intervention activities and then deliver these activities consistently to a large number of individuals in need. Given that eHealth interventions grounded in a well-delineated theoretical model for change are more likely to be effective and that eHealth interventions can be costly to develop, assuring the match of final intervention content and activities to the underlying model is a key step. We propose to apply the concept of "content validity" as a crucial checkpoint to evaluate the extent to which proposed intervention activities in an eHealth intervention program are valid (eg, relevant and likely to be effective) for the specific mechanism of change that each is intended to target and the intended target population for the intervention. OBJECTIVE: The aims of this paper are to define content validity as it applies to model-based eHealth intervention development, to present a feasible method for assessing content validity in this context, and to describe the implementation of this new method during the development of a Web-based intervention for children. METHODS: We designed a practical 5-step method for assessing content validity in eHealth interventions that includes defining key intervention targets, delineating intervention activity-target pairings, identifying experts and using a survey tool to gather expert ratings of the relevance of each activity to its intended target, its likely effectiveness in achieving the intended target, and its appropriateness with a specific intended audience, and then using quantitative and qualitative results to identify intervention activities that may need modification. We applied this method during our development of the Coping Coach Web-based intervention for school-age children. RESULTS: In the evaluation of Coping Coach content validity, 15 experts from five countries rated each of 15 intervention activity-target pairings. Based on quantitative indices, content validity was excellent for relevance and good for likely effectiveness and age-appropriateness. Two intervention activities had item-level indicators that suggested the need for further review and potential revision by the development team. CONCLUSIONS: This project demonstrated that assessment of content validity can be straightforward and feasible to implement and that results of this assessment provide useful information for ongoing development and iterations of new eHealth interventions, complementing other sources of information (eg, user feedback, effectiveness evaluations). This approach can be utilized at one or more points during the development process to guide ongoing optimization of eHealth interventions.

Feasibility of a screening program for at-risk children following accidental injury.

Screening is recommended as a simple method for identifying those who should be monitored for risk following trauma. Effective methods for implementing large-scale screening programs are yet to be established. This study tested the feasibility and utility of a screening program with hospitalized youth exposed to injury in 3 Australian hospitals. Eligible families (N = 1,134) were contacted and 546 children (48.0%) screened for risk of posttraumatic stress disorder (PTSD) at 1-2 weeks postinjury. There were 95 (17.4%) children whose screen result was at risk. A rescreening phase was introduced during the study, with 68 children completing the rescreen at 4-6 weeks postinjury, and 26 (38.2% of those rescreened) still at risk. Of those initially screened, 29 (5.3%) completed diagnostic assessments, 21 (3.8%) were diagnosed with partial or full PTSD, and 17 (3.1%) commenced treatment. Screening was successful at identifying and reaching children with PTSD, but the response rate was lower than expected, which limited the utility of the program. The addition of a rescreening phase demonstrated that not all at-risk children required intervention. These findings replicate previous studies that have shown natural remission in PTSD symptoms and highlight the potential for rescreening as part of a watchful waiting approach.

PTSD perpetuates pain in children with traumatic brain injury.

OBJECTIVE: This study tested theoretical models of the relationship between pain and posttraumatic stress disorder (PTSD) in children with traumatic brain injury (TBI). METHODS: Participants consisted of 195 children aged 6-15 years presenting to 1 of 3 Australian hospitals following a mild-severe TBI. Children were assessed at 3, 6, and 18 months after their accident for PTSD (via the Clinician-Administered PTSD Scale for Children and Adolescents [CAPS-CA] clinical interview) as well as physical pain (via the Child Health Questionnaire, 50-item version [CHQ-PF50]). Trained clinicians administered the CAPS-CA at home visits, and the CHQ-PF50 was collected through questionnaires. RESULTS: Structural equation modeling found the data supported the mutual maintenance model and also the nested perpetual avoidance model. CONCLUSIONS: Both models indicate PTSD is driving the presence of pain, and not vice versa. A fourth model stating this was proposed. Therefore, it may be useful to address PTSD symptoms in treating child pain for expediting recovery.

Prospective evaluation of parent distress following pediatric burns and identification of risk factors for young child and parent posttraumatic stress disorder.

OBJECTIVE: Early childhood is a high-risk time for exposure to potentially traumatic medical events. We have previously reported that 10% of young children continue to have posttraumatic stress disorder (PTSD) 6 months after burn injury. This study aimed to 1) document the prevalence and prospective change in parental psychological distress over 6 months following their child's burn injury and 2) identify risk factors for posttraumatic stress symptoms (PTSS) in young children and their parents. METHODS: Participants were 120 parents of 1-6-year-old children with unintentional burn injuries. Data were collected within 2 weeks, 1 month, and 6 months of burn injury using developmentally sensitive diagnostic interviews and questionnaires. RESULTS: Within the first month, ∼ 25% of parents had a probable PTSD diagnosis, and moderate to extremely severe levels of depression, anxiety, and stress. Distress levels decreased significantly over time; however, 5% of parents still had probable PTSD at 6 months. Hierarchical multiple regression and path analyses indicated that parent posttraumatic stress reactions contributed significantly to the development and maintenance of child PTSS. Other risk factors for child PTSS included premorbid emotional and behavioral difficulties and larger burn size. Risk factors identified for parent PTSS included prior trauma history, acute distress, greater number of child invasive procedures, guilt, and child PTSS. CONCLUSIONS: The findings from this study suggest that parents' responses to a traumatic event may play a particularly important role in a young child's psychological recovery. However, further research is needed to confirm the direction of the relationship between child and parent distress. This study identified variables that could be incorporated into screening tools or targeted by early intervention protocols to prevent the development of persistent child and parent PTSS following medical trauma.

The use of diaries in psychological recovery from intensive care.

Intensive care patients frequently experience memory loss, nightmares, and delusional memories and some may develop symptoms of anxiety, depression, and post-traumatic stress. The use of diaries is emerging as a putative tool to 'fill the memory gaps' and promote psychological recovery. In this review, we critically analyze the available literature regarding the use and impact of diaries for intensive care patients specifically to examine the impact of diaries on intensive care patients' recovery. Diversity of practice in regard to the structure, content, and process elements of diaries for intensive care patients exists and emphasizes the lack of an underpinning psychological conceptualization. The use of diaries as an intervention to aid psychological recovery in intensive care patients has been examined in 11 studies, including two randomized controlled trials. Inconsistencies exist in sample characteristics, study outcomes, study methods, and the diary intervention itself, limiting the amount of comparison that is possible between studies. Measurement of the impact of the diary intervention on patient outcomes has been limited in both scope and time frame. Furthermore, an underpinning conceptualization or rationale for diaries as an intervention has not been articulated or tested. Given these significant limitations, although findings tend to be positive, implementation as routine clinical practice should not occur until a body of evidence is developed to inform methodological considerations and confirm proposed benefits.

The diagnosis of posttraumatic stress disorder in school-aged children and adolescents following pediatric intensive care unit admission.

OBJECTIVES: This study explored the diagnosis of posttraumatic stress disorder (PTSD) in children and adolescents following pediatric intensive care unit (PICU) admission. Specifically, the study aimed to describe the presentation and prevalence of PTSD symptoms 6 months postdischarge, explore the validity of the DSM-IV PTSD algorithm and alternative PTSD algorithm (PTSD-AA) in school-aged children and adolescents, and examine the diagnostic utility of Criterion C3 (inability to recall aspects of a trauma) in this cohort. METHODS: Participants were 59 children aged 6-16, admitted to PICU for at least 8 hours. PTSD was assessed via diagnostic interview (Children's PTSD Inventory) 6 months following PICU discharge. RESULTS: The PTSD-AA was found to provide the most valid measure of PTSD at 6 months. Removing Criterion C3 improved the validity of Criterion C. CONCLUSIONS: This study supports the use of the PTSD-AA excluding Criterion C3 for identifying highly traumatized children and adolescents following PICU admission.
