Making Sense of "Somatization": A Systematic Review of its Relationship to Pediatric Pain

Data visualization as an intervention for pediatric chronic pain: a pilot feasibility study protocol for a randomized controlled crossover trial

Background

Chronic pain is a common and costly condition in youth, associated with negative implications that reach far beyond the pain experience itself (e.g., interference with recreational, social, and academic activities, mental health sequelae). As a self-appraised condition, pain experience is influenced by patient’s biases and meaning-making in relation to their symptoms and triggers. We propose that interacting with self-reported data will impact the experience of pain by altering understanding and expectations of symptom experience and how pain interacts with other factors (e.g., sleep, emotions, social interactions). In this study, we aim to establish the feasibility and acceptability of using a data visualization platform to track and monitor symptoms and their relationship with other factors, versus simply daily reporting of symptoms using a smartphone-based Ecological Momentary Assessment (EMA).

Methods

This protocol is for a randomized, single-center, open-label crossover trial. We aim to recruit 50 typically developing youth aged 12–18 years with chronic pain to take part in two phases of data collection. The trial will utilize an A-B counterbalanced design in which participants will be randomly assigned to receive either Part A (EMA alone for 7 days) or Part B (EMA plus visualization platform for 7 days) first and then receive the opposite phase after a 7-day break (washout period). Key outcomes will be participant reports of acceptability and feasibility, EMA completion rates, barriers, and perceptions of the benefits or risks of participation. Secondary exploratory analyses will examine the relationship between EMA-reported symptoms over time and in relation to baseline measures, as well as pilot data on any improvements in symptoms related to engaging with the data visualization platform.

Discussion

This protocol describes the feasibility and pilot testing of a novel approach to promoting self-management and facilitating symptom appraisal using visualized data. We aim to determine whether there is a sufficient rationale, both from the perspective of feasibility and patient satisfaction/acceptability, to conduct a larger randomized controlled trial of this intervention. This intervention has the potential to support clinical care for youth with chronic pain and other conditions where self-appraisal and understanding of symptom patterns are a critical component of functional recovery.

When feelings hurt: Learning how to talk with families about the role of emotions in physical symptoms

Emotions are at the core of all human experiences, but talking about emotions is challenging, particularly in the context of medical encounters focused on somatic symptoms. Transparent, normalizing, and validating communication about the mind-body connection opens the door for respectful, open dialogue between the family and members of the care team, acknowledging the lived experience that is brought to the table in understanding the problem and co-creating a solution.

Pediatric Avoidant-Restrictive Food Intake Disorder and gastrointestinal-related Somatic Symptom Disorders: Overlap in clinical presentation

Certain presentations of Avoidant/Restrictive Food Intake Disorder (ARFID) and Somatic Symptom and Related Disorders (SSRDs) have conceptual overlap, namely, distress and impairment related to a physical symptom. This study compared characteristics of pediatric patients diagnosed with ARFID to those with gastrointestinal (GI)-related SSRD. A 5-year retrospective chart review at a tertiary care pediatric hospital comparing assessment data of patients with a diagnosis of ARFID (n = 62; 69% girls, M_age = 14.08 years) or a GI-related SSRD (n = 37; 68% girls, M_age = 14.25 years). Patients diagnosed with ARFID had a significantly lower percentage of median BMI than those with GI-related SSRD. Patients diagnosed with ARFID were most often assessed in the Eating Disorders Program, whereas patients diagnosed with an SSRD were most often assessed by Consultation-Liaison Psychiatry. Groups did not differ on demographics, psychiatric diagnoses, illness duration, or pre-assessment services/medications. GI symptoms were common across groups. Patients diagnosed with an SSRD had more co-occurring medical diagnoses. A subset (16%) of patients reported symptoms consistent with both diagnoses. Overlap is observed in the clinical presentation of pediatric patients diagnosed with ARFID or GI-related SSRD. Some group differences emerged, including anthropometric measurements and co-occurring medical conditions. Findings may inform diagnostic classification and treatment approach.

Somatization and Somatic Symptom Disorder and its overlap with dimensionally measured personality pathology: A systematic review

OBJECTIVE

Difficulties in the assessments of Somatoform Disorders (SD) and Personality Disorders (PD) regarding operationalization, arbitrary thresholds, and reliability led to a shift from categorical to dimensional models in the DSM-5. Empirical research data postulates a continuous level of severity in both groups of diseases. The aim of this systematic review was to investigate the overlap between somatization and personality pathology.

METHODS

Until July 2020, we conducted a systematic literature search with PubMed, Web of Science and SCOPUS. We specifically reviewed current empirical data on the Alternative Model of Personality Disorders (AMPD) and Somatic Symptom Disorder (SSD) and SD. Data was drawn out using predefined data panels. Results were reflected in the context of the Hierarchical Taxonomy of Psychopathology (HiTOP) model. Risk of bias was assessed due to blinding, randomization, selective reporting, incomplete data, and attribution bias.

RESULTS

A total of eight studies (N = 2979) met the inclusion criteria. Whereas categorical measures revealed mixed results, positive correlations between SD/SSD and dimensionally measured personality functioning were present in four studies (N = 1741). In three studies (N = 2025) correlations between SD/SSD and neuroticism/negative affectivity (d = 0.22-1.041) were present. Moreover, harm avoidant (d = 0.526 - 0.826) and self-defeating traits (d = 0.892) revealed significant associations with somatization.

CONCLUSIONS

Dimensional personality assessments are highly neglected in patients with SSD and warrant further research. However, in line with the HiTOP model, there is tentative evidence that somatization can be described as an independent personality trait, which shows most striking overlaps with self-pathologies (Criterion A) and the trait of negative affectivity (Criterion B).

Identifying the content and context of pain within paediatric rheumatology healthcare professional curricula in the UK: a summative content analysis

BACKGROUND

The curriculum for professionals working in paediatric rheumatology should include pain but it is unclear to what extent this currently occurs. The aim of this study was to identify pain-related curriculum content and the context in which pain is presented in educational and training documentation for healthcare professionals in this clinical speciality.

METHODS

Core curricula documents from UK based professional organisations were identified in partnership with healthcare professionals. Documents were analysed using a summative content analysis approach. Key pain terms were quantified and weighted frequencies were used to explore narrative pain themes. Latent content was interpreted qualitatively to explore the context within which pain terms were positioned.

RESULTS

Nine curriculum documents were identified and analysed from doctors, nurses, physiotherapists and occupational therapists specialising in paediatric rheumatology. Pain themes represented a mean percentage of 1.51% of text across all documents. Pain was rarely presented in the context of both inflammatory and non-inflammatory condition types despite being a common feature of each. Musculoskeletal pain was portrayed simply as a 'somatic' symptom, rather than as a complex phenomenon involving biological and psychosocial processes. Content around the assessment and management of pain was vague and inexplicit.

CONCLUSION

Current educational and training documentation in paediatric rheumatology do not include core pain topics. Curricula for these healthcare professionals would benefit from updates in contemporary pain theories and examples of in-context, evidence-based pain practices. This should be a priority starting point for optimising patient pain care in paediatric musculoskeletal healthcare.
