Validation and Clinical Application of a Biopsychosocial Model of Pain Intensity and Functional Disability in Patients with a Pediatric Chronic Pain Condition Referred to a Subspecialty Clinic

Abstract

Background. Pediatric chronic pain is considered to be a multidimensional construct that includes biological, psychological, and social components. Methods. The 99 enrolled study patients (mean age 13.2 years, 71% female, 81% Caucasian) and an accompanying parent completed a series of health-related questionnaires at the time of their initial appointment in a pediatric chronic pain medicine clinic. Results. Significant correlations (r ≥ 0.30, P < 0.05) were observed between pediatric chronic pain intensity and patient anxiety, patient depression, patient pain coping, parent chronic pain intensity, and parent functional disability. Pediatric chronic pain intensity was significantly associated with patient anxiety (P = 0.002). Significant correlations (r ≥ 0.30, P < 0.05) were observed between pediatric functional disability and patient chronic pain intensity, patient anxiety, patient depression, patient pain coping, parent chronic pain intensity, parent functional disability, parent anxiety, parent depression, and parent stress. Pediatric functional disability was significantly associated with patient chronic pain intensity (P = 0.025), patient anxiety (P = 0.021), patient pain coping (P = 0.009), and parent functional disability (P = 0.027). Conclusions. These findings provide empirical support of a multidimensional Biobehavioral Model of Pediatric Pain. However, the practical clinical application of the present findings and much of the similar previously published data may be tenuous.

Psychological Factors that Influence Decision-Making Regarding Trauma-Related Pain in Adolescents with Temporomandibular Disorder

“…To understand the psychological factors related to pain and trauma in young adolescents, we must consider the multidimensional nature of adolescent TMD, within the context of the biopsychosocial model, because adolescents are vulnerable in terms of functional TMJ pain derived from the interplay between organic dysfunction and psychosocial factors 52,53 . Psychological stress resulting from events occurring at school and in the family, and the related muscle hyperactivity and muscle fatigue, as well as oral habits, have been suggested as etiological factors 2 .…”

Pain Intensity, Headache Frequency, and the Behavioral Activation and Inhibition Systems

“…3 However, "biopsychosocial" models and treatments often focus more on psychosocial factors than biological ones; the "bio" piece of these models is often underdeveloped. [4][5][6][7] A greater focus on biological factors-in particular the role that central nervous system structures and processes play in experience of pain-may be used to inform the development of neuromodulatory interventions that could enhance the efficacy of psychosocial interventions, and help to better understand how psychosocial interventions influence pain. [8][9][10][11][12] Two neurophysiological factors that could potentially play an important role in pain and its effects on behavior are the behavioral inhibition and behavioral activation systems (BIS and BAS, respectively).…”

Ask me: Children's experiences of pain explored using the draw, write, and tell method

“…Emotional responses have been shown not only to exacerbate and intensify pain, but also lower a child's pain threshold (LeMay et al., ). These findings highlight the need to consider assessment and interventions that go beyond addressing physical symptoms of pain to include the complex interplay of emotional factors (Vetter et al., ).…”
