Mediator and moderator effects in developmental and behavioral pediatric research.

The terms mediation and moderation are defined and clarified with particular emphasis on the role of mediational and moderational analyses in developmental and behavioral pediatric research. The article highlights the applicability of mediational and moderational analyses to longitudinal, intervention, and risk and protective factor research, and it provides basic information about how these analyses might be conducted. Also included is a discussion of various ways that both mediator and moderator variables can be incorporated into a single model. The article concludes with extended examples of both types of analyses using a longitudinal pediatric study for illustration. The article provides recommendations for applying mediational and moderational research in clinical practice.

Family functioning in children and adolescents with spina bifida: an evidence-based review of research and interventions.

ABSTRACT. Research on the adjustment of families of children with spina bifida is reviewed, with a focus on delineating the impact of spina bifida on family functioning, the strengths and weaknesses of past research, and the needs for future evidence-based research on family interventions with this population. PsychINFO and MEDLINE literature searches were used to identify studies of family functioning and family-based interventions for children with spina bifida. Identified studies were empirically evaluated for the presence or absence of key methodological or analytic criteria. Thirty-two studies of family functioning were identified from 25 separate research groups; most studies displayed significant methodological limitations. No published studies of interventions to promote adaptive family functioning were identified. Methodologically sound, longitudinal, and theory-driven studies of family functioning are needed, as are randomized family-based intervention trials to promote adaptive functioning and better psychosocial outcomes in families of children with spina bifida. Specific recommendations for future work as well as clinical implications are noted.

Pediatric Pain Screening Tool: rapid identification of risk in youth with pain complaints.

Family functioning and posttraumatic stress symptoms in youth and their parents after unintentional pediatric injury

19.5 billion dollars annually in the United States alone. Risk-stratified care is known to improve outcomes in adults with chronic pain. However, no tool exists to stratify youth who present with pain complaints to appropriate interventions. The Pediatric Pain Screening Tool (PPST) presented here assesses prognostic factors associated with adverse outcomes among youth and defines risk groups to inform efficient treatment decision making. Youth (n = 321, ages 8-18, 90.0% Caucasian, 74.8% female) presenting for multidisciplinary pain clinic evaluation at a tertiary care center participated. Of these, 195 (61.1%) participated at 4-month follow-up. Participants completed the 9-item PPST in addition to measures of functional disability, pain catastrophizing, fear of pain, anxiety, and depressive symptoms. Sensitivity and specificity for the PPST ranged from adequate to excellent, with regard to significant disability (78%, 68%) and high emotional distress (81%, 63%). Participants were classified into low- (11%), medium- (32%), and high- (57%) risk groups. Risk groups did not significantly differ by pain diagnosis, location, or duration. Only 2% to 7% of patients who met reference standard case status for disability and emotional distress at 4-month follow-up were classified as low risk at baseline, whereas 71% to 79% of patients who met reference standard case status at follow-up were classified as high risk at baseline. A 9-item screening tool identifying factors associated with adverse outcomes among youth who present with pain complaints seems valid and provides risk stratification that can potentially guide effective pain treatment recommendations in the clinic setting.

The Pivotal Role of Pediatric Psychology in Chronic Pain: Opportunities for Informing and Promoting New Research and Intervention in a Shifting Healthcare Landscape

This study examined the association between family functioning and the development of posttraumatic stress symptoms (PTSS) in youth and parents following an unintentional traumatic injury of a child. Fifty-one parent-child dyads completed questionnaires and a structured interview assessing PTSS and family functioning. Multiple regression analyses were applied to evaluate the contribution of family functioning to the development of PTSS after controlling for demographic characteristics and known predictors. Family functioning had both direct and moderating influences on the development of PTSS in parents. We were unable to demonstrate a systematic impact of family functioning on the development of PTSS in children from the same families.

Collecting and Managing Multisource and Multimethod Data in Studies of Pediatric Populations

Purpose of ReviewIn the context of new efforts to formulate more comprehensive diagnostic and treatment processes for chronic pain conditions, this review aims to provide an overview of some of the most salient developments in the diagnosis and clinical treatment of pediatric chronic pain and to delineate the current and future role of clinical pediatric psychologists in these efforts.Recent FindingsThe acceptance and promotion of the multidisciplinary approach to pediatric pain management has had an especially significant impact on the field of pediatric psychology. Though chronic pain was historically conceptualized as a biomedical problem, psychology is increasingly viewed as a routine, integral, and component part of treatment. With this evolving biopsychosocial paradigm, pediatric psychology is poised to help shape the development of this field, contributing to emerging conceptual and diagnostic frameworks via consultation, research, clinical care, and education.SummaryThis review discusses the role of pediatric psychologists as collaborators in emerging diagnostic and assessment frameworks, leaders in pain-related research, drivers of clinical care, and educators for providers, patients, and the lay public. With increased opportunities to enhance the conceptualization and treatment of pediatric pain, pediatric psychologists have an important role to play in reducing the prevalence and persistence of pediatric pain.
