  • Pediatric-Collaborative Health Outcomes Information Registry (Peds-CHOIR): a learning health system to guide pediatric pain research and treatment. Pain Bhandari, R. P., Feinstein, A. B., Huestis, S. E., Krane, E. J., Dunn, A. L., Cohen, L. L., Kao, M. C., Darnall, B. D., Mackey, S. C. 2016; 157 (9): 2033-2044


    The pediatric adaptation of the Collaborative Health Outcomes Information Registry (Peds-CHOIR) is a free, open-source, flexible learning health care system (LHS) that meets the call by the Institute of Medicine for the development of national registries to guide research and precision pain medicine. This report is a technical account of the first application of Peds-CHOIR with 3 aims: (1) to describe the design and implementation process of the LHS; (2) to highlight how the clinical system concurrently cultivates a research platform rich in breadth (eg, clinic characteristics) and depth (eg, unique patient- and caregiver-reporting patterns); and (3) to demonstrate the utility of capturing patient-caregiver dyad data in real time, with dynamic outcomes tracking that informs clinical decisions and delivery of treatments. Technical, financial, and systems-based considerations of Peds-CHOIR are discussed. Cross-sectional retrospective data from patients with chronic pain (N = 352; range, 8-17 years; mean, 13.9 years) and their caregivers are reported, including National Institutes of Health Patient-Reported Outcomes Measurement Information System (PROMIS) domains (mobility, pain interference, fatigue, peer relations, anxiety, and depression) and the Pain Catastrophizing Scale. Consistent with the literature, analyses of initial visits revealed impairments across physical, psychological, and social domains. Patients and caregivers evidenced agreement in observable variables (mobility); however, caregivers consistently endorsed greater impairment regarding internal experiences (pain interference, fatigue, peer relations, anxiety, and depression) than patients' self-report. A platform like Peds-CHOIR highlights predictors of chronic pain outcomes on a group level and facilitates individually tailored treatment(s). Challenges of implementation and future directions are discussed.

  • Single-Case Research Design in Pediatric Psychology: Considerations Regarding Data Analysis JOURNAL OF PEDIATRIC PSYCHOLOGY Cohen, L. L., Feinstein, A., Masuda, A., Vowles, K. E. 2014; 39 (2): 124-137


    Single-case research allows for an examination of behavior and can demonstrate the functional relation between intervention and outcome in pediatric psychology. This review highlights key assumptions, methodological and design considerations, and options for data analysis.Single-case methodology and guidelines are reviewed with an in-depth focus on visual and statistical analyses.Guidelines allow for the careful evaluation of design quality and visual analysis. A number of statistical techniques have been introduced to supplement visual analysis, but to date, there is no consensus on their recommended use in single-case research design.Single-case methodology is invaluable for advancing pediatric psychology science and practice, and guidelines have been introduced to enhance the consistency, validity, and reliability of these studies. Experts generally agree that visual inspection is the optimal method of analysis in single-case design; however, statistical approaches are becoming increasingly evaluated and used to augment data interpretation.

  • Ecological system influences in the treatment of pediatric chronic pain PAIN RESEARCH & MANAGEMENT Logan, D. E., Engle, L., Feinstein, A. B., Sieberg, C. B., Sparling, P., Cohen, L. L., Conroy, C., Driesman, D., Masuda, A. 2012; 17 (6): 407-411


    Family, school and the peer network each shape the chronic pain experience of the individual child, and each of these contexts also represents a domain of functioning often impaired by chronic pain. The goal of the present article is to summarize what is known about these bidirectional influences between children with pain and the social systems that surround them. Case reports that illustrate these complex, transactional forces and their ultimate impact on the child's pain-related functioning are included. A case involving siblings participating in an intensive interdisciplinary program for functional restoration and pain rehabilitation highlights how parents change through this treatment approach and how this change is vital to the child's outcomes. Another case involving a child undergoing intensive interdisciplinary treatment illustrates how school avoidance can be treated in the context of pain rehabilitation, resulting in successful return to the regular school environment. Finally, an acceptance and commitment therapy-focused group intervention for children with sickle cell disease and their parents demonstrates the benefits of peer contact as an element of the therapeutic intervention.

  • The Influence of Parent Preprocedural Anxiety on Child Procedural Pain: Mediation by Child Procedural Anxiety JOURNAL OF PEDIATRIC PSYCHOLOGY Bearden, D. J., Feinstein, A., Cohen, L. L. 2012; 37 (6): 680-686


    Data suggest parents' preprocedural anxiety is related to children's acute procedural anxiety and pain. This study examined the temporal relations among these constructs to determine whether children's anxiety mediates the relation between parents' anticipatory anxiety and children's procedural pain.A total of 90 preschoolers receiving immunizations, their parents, and the nurses rated children's procedural anxiety and pain. Parents provided ratings of their own preprocedural anxiety.Bootstrapping analyses revealed that children's procedural anxiety mediated the relation between parents' preprocedural anxiety and children's procedural pain according to parents' report and nurses' report but not children's self-report of anxiety and pain.Analyses suggest that children's procedural anxiety mediates the relation between parents' anticipatory anxiety and children's procedural pain. Thus, targeting parents' preprocedural anxiety might be beneficial to the parents as well as the children undergoing a distressing medical procedure.

  • Pain Intensity, Psychological Inflexibility, and Acceptance of Pain as Predictors of Functioning in Adolescents with Juvenile Idiopathic Arthritis: A Preliminary Investigation JOURNAL OF CLINICAL PSYCHOLOGY IN MEDICAL SETTINGS Feinstein, A. B., Forman, E. M., Masuda, A., Cohen, L. L., Herbert, J. D., Moorthy, L. N., Goldsmith, D. P. 2011; 18 (3): 291-298


    Juvenile Idiopathic Arthritis (JIA) is a chronic rheumatic disease associated with pain and maladjustment. This study investigated whether pain, acceptance of pain, and psychological inflexibility uniquely predicted functional disability, anxiety, general quality of life (QOL), and health-related quality of life (HQOL) among adolescents with JIA. Twenty-three adolescents with JIA and pain were recruited from a pediatric rheumatology clinic. Participants completed self-report measures pertaining to the key study variables. A series of multiple regression analyses demonstrated that higher pain uniquely predicted higher functional disability. Greater psychological inflexibility uniquely predicted higher anxiety, lower general QOL, and lower HQOL. Increases in acceptance of pain were found to be uniquely related to increases in general QOL. These data confirm prior findings that pain impacts functioning, and provide preliminary findings that psychological inflexibility and acceptance may be important targets of psychological intervention for youth with JIA and pain to improve functioning and QOL.

  • Cognitive Defusion Versus Thought Distraction: A Clinical Rationale, Training, and Experiential Exercise in Altering Psychological Impacts of Negative Self-Referential Thoughts BEHAVIOR MODIFICATION Masuda, A., Feinstein, A. B., Wendell, J. W., Sheehan, S. T. 2010; 34 (6): 520-538


    Using two modes of intervention delivery, the present study compared the effects of a cognitive defusion strategy with a thought distraction strategy on the emotional discomfort and believability of negative self-referential thoughts. One mode of intervention delivery consisted of a clinical rationale and training (i.e., Partial condition). The other mode contained a condition-specific experiential exercise with the negative self-referential thought in addition to the clinical rationale and training (i.e., Full condition). Nonclinical undergraduates were randomly assigned to one of five protocols: Partial-Defusion, Full-Defusion, Partial-Distraction, Full-Distraction, and a distraction-based experimental control task. The Full-Defusion condition reduced the emotional discomfort and believability of negative self-referential thoughts significantly more than other comparison conditions. The positive results of the Full-Defusion condition were also found among participants with elevated depressive symptoms.
