CLINICAL EVIDENCE

Supporting Research for The Middle Moment and Guided Agency.

This registry compiles peer-reviewed clinical research investigating the impact of control, agency, and somatic stress on procedural timelines and pediatric patient care.

01Clinical Database Category

Powerlessness and Lack of Control as the Driver of Pediatric Clinical Anxiety

The root of clinical resistance and procedural hesitation

World Journal of Clinical Pediatrics, 5(2), 143–150Ref: 2016

Minimizing Pediatric Healthcare-Induced Anxiety and Trauma

Lerwick, J.L. (2016). Minimizing Pediatric Healthcare-Induced Anxiety and Trauma. World Journal of Clinical Pediatrics, 5(2), 143–150.

Key Scientific Finding

"Children are often subject to psychological trauma because they lack control of their environment. This sense of helplessness, coupled with fear and pain, causes children to feel powerless in healthcare settings. These emotional responses delay important medical treatment, take more time to complete, and reduce patient satisfaction."

The Compounding Effect: How Unmanaged Anxiety Shapes Future Healthcare Experiences

The compounding loop of procedural trauma memory

Frontiers in Public Health, 7:250Ref: 2019

Hospitalized Children: Anxiety, Coping Strategies, and Pretend Play

Frontiers in Public Health (2019). Hospitalized Children: Anxiety, Coping Strategies, and Pretend Play. Frontiers in Public Health, 7:250.

Key Scientific Finding

"In the short term, extreme distress may compromise the completion of a required medical procedure. In the long term, it may lead to difficulties in future encounters that discourage the use of medical treatments."

ScienceDirect, February 2025Ref: 2025

Play-Based Training Program for Overcoming Hospital Fear in Children

ScienceDirect (2025). Play-Based Training Program for Overcoming Hospital Fear in Children. ScienceDirect, February 2025.

Key Scientific Finding

"Painful experiences during blood draws and other invasive procedures can lead to fear of future procedures. Previous painful experiences, fear of needles, and anxiety can lead to avoidance of medical procedures entirely."

The Physiological Impact of Anxiety on Procedure Outcomes

The clinical and operational case for emotional regulation

PubMed, 2018Ref: 2018

Anxiety and Salivary Cortisol Levels in Children Undergoing Esophago-Gastro-Duodenoscopy Under Sedation

PubMed (2018). Anxiety and Salivary Cortisol Levels in Children Undergoing Esophago-Gastro-Duodenoscopy Under Sedation. PubMed, 2018.

Key Scientific Finding

"Higher anxiety in children undergoing procedures results in increased medication requirements and longer procedural durations, which can cause potential complications."

PMC/NIH, 2024Ref: 2024

Effect of Educational Brochures on Preprocedural Anxiety in Pediatric Endoscopy: A Randomized Controlled Trial

PMC/NIH (2024). Effect of Educational Brochures on Preprocedural Anxiety in Pediatric Endoscopy: A Randomized Controlled Trial. PMC/NIH, 2024.

Key Scientific Finding

"Preoperative anxiety has been linked to increased pain sensitivity, poor compliance, and in some cases the cancellation of procedures. Up to 70% of children undergoing surgical procedures experience pronounced preoperative distress."

Non-Pharmacological Interventions and Cortisol Reduction

Physiological modification of pediatric stress responses

PMC/NIH, 2023Ref: 2023

Investigating Non-Pharmacological Stress Reduction Interventions in Pediatric Patients Confirmed with Salivary Cortisol Levels: A Systematic Review

PMC/NIH Systematic Review (2023). Investigating Non-Pharmacological Stress Reduction Interventions in Pediatric Patients Confirmed with Salivary Cortisol Levels: A Systematic Review. PMC/NIH, 2023.

Key Scientific Finding

"Non-pharmacological interventions hold a promising role in reducing levels of anxiety or distress in children, as confirmed with salivary cortisol measurement. Anxiety and distress were found to be reduced in the majority of the studies reviewed."

PMC/NIH, 2014Ref: 2014

Interventions to Improve Cortisol Regulation in Children: A Systematic Review

PMC/NIH Systematic Review (2014). Interventions to Improve Cortisol Regulation in Children: A Systematic Review. PMC/NIH, 2014.

Key Scientific Finding

"Cortisol activity can be altered by psychosocial interventions. These findings indicate physiologic plasticity that can be leveraged by interventions and suggest it may be possible to repair regulatory systems after childhood adversity — which could inform strategies for reducing health disparities and promoting lasting improvements in health."

Chronic Stress and Long-Term Health Consequences in Children

Somatic equity and developmental stress consequences

Hormone Research in Paediatrics, 2023Ref: 2023

Stress and Growth in Children and Adolescents

Karger Publishers (2023). Stress and Growth in Children and Adolescents. Hormone Research in Paediatrics, 2023.

Key Scientific Finding

"Early-life adversities, emotional or physical, have been associated with long-term negative physical and mental health outcomes. Targeted interventions to reduce stress during infancy, childhood, and adolescence can have far-reaching benefits to long-term health."

PMC/NIH, 2019Ref: 2019

Extending the Toxic Stress Model into Adolescence: Profiles of Cortisol Reactivity

PMC/NIH (2019). Extending the Toxic Stress Model into Adolescence: Profiles of Cortisol Reactivity. PMC/NIH, 2019.

Key Scientific Finding

"A greater sense of control is correlated with better mental health outcomes and less stress across multiple life domains. Children who develop perceived control over themselves and their environment demonstrate measurably better health outcomes."

Important Regulatory Notice & Disclaimer

Cosmos Continuum has not conducted independent clinical trials on the specific outcomes of StoryWall or Breathe With Me in pediatric settings within the United States. The research compiled here supports the foundational principles underlying Guided Agency — the relationship between control, anxiety, and clinical outcomes in children — rather than constituting direct product validation.

As clinical deployments expand, Cosmos Continuum is committed to developing its own evidence base in partnership with clinical institutions.
