Carl L. von Baeyer is a Canadian psychologist,academic,and author. He is a professor emeritus of psychology at the University of Saskatchewan. [1]
Von Baeyer is most known for his work on the assessment of pain in children. He was awarded the 2017 Jeffrey Lawson Award for Advocacy in Children's Pain Relief from the American Pain Society. His authored works include publications in academic journals including Pain and The Journal of Pain [2] as well as book chapters. Von Baeyer is a Fellow of the Canadian Psychological Association. [3]
He has explored and advocated for the benefits and feasibility of a shared parenting arrangement where both parents work part-time while also spending time at home with their children. [4]
Von Baeyer completed his BA in psychology in 1971 from the University of British Columbia,followed by an MA in 1974 and PhD in 1978 from the University of Waterloo in clinical psychology. [1]
Von Baeyer joined the faculty of the University of Saskatchewan in Saskatoon in 1978,assuming various positions. His noteworthy roles included terms as Director of Clinical Psychology Training for the PhD program and chair of the Behavioural Sciences Research Ethics Board. [1]
At Royal University Hospital in Saskatoon,von Baeyer founded and directed the Internship (Residency) Training in Clinical Psychology from 1982 to 1989 and pioneered the Pediatric Complex Pain Clinic Pilot Project in 2009. [1]
Additionally,from 2002 he served as one of five co-principal investigators and co-founders of 'Pain in Child Health',a training initiative in health research funded by the Canadian Institutes of Health Research. [5] He chaired the ChildKind International Resource Library from 2015 to 2018. [6]
After retirement as Professor Emeritus from the University of Saskatchewan [1] he moved from Saskatoon to Winnipeg. There he co-chaired the Pediatric Pain Interdisciplinary Interest Group at the Children's Hospital,Health Sciences Centre,Winnipeg,from 2013 to 2017.
Von Baeyer has authored or co-authored over 120 research articles. His works have been cited over 17,000 times according to Google Scholar. [2]
In his 1994 research,von Baeyer investigated whether repeated clinical pain measurement affects perceived pain intensity and distress in low-back-pain patients,finding that daily self-monitoring does not significantly alter subjective pain intensity over an 8-day period. [7]
Much of von Baeyer's work has focused on pediatric pain. His 2001 collaborative study introduced and validated the Faces Pain Scale-Revised (FPS-R),a six-face adaptation of the original seven-face FPS for children's pain assessment. It demonstrated a strong correlation with visual analogue and colored analogue scales,suitable for ages 4–12,adhering to a 0-10 metric. [8]
In a 2004 publication,he examined the impact of children's memories of painful experiences on their later reactions to pain and healthcare interventions,discussing developmental,individual,situational,and methodological factors,as well as strategies to mitigate negative consequences. [9]
A systematic review published in 2007 was commissioned by the Initiative on Methods,Measurement,and Pain Assessment in Clinical Trials (IMMPACT). [10] It focused on observational pain scales for children aged 3 to 18. It identified 20 scales,recommended specific ones for acute pain contexts,and suggested further research for chronic pain assessment. [11]
In 2009,he presented validation data supporting the use of the Numerical Rating Scale (NRS) for self-report of pain intensity in children aged 8 years and older,demonstrating functional equivalence with other self-report pain scales like the Faces Pain Scale-Revised (FPS-R) and the Visual Analogue Scale (VAS). [12] Moreover,in 2017,he co-edited a book titled Chronic and Recurrent Pain,which highlighted the prevalence and impact of pediatric chronic pain,discussing various conditions,their consequences,and advocating for improved recognition and treatment strategies to advance understanding and care for affected children. [13]
Von Baeyer's 2018 study investigated the validity and reliability of the Verbal Numerical Rating Scale (VNRS) as a measure of pain intensity in children aged 4 to 17 years,finding strong support for its use in children aged 6 to 17 years but cautioning against its use in those aged 4 and 5 years due to weaker convergent validity. [14] In his 2019 work,he studied clinically significant changes in pain scores among children with painful conditions,using VNRS and FPS-R scales. Taking into account initial pain intensity and patient characteristics,the study offered guidelines for clinical practice and research. [15]
A later work published in 2021 examined the suitability of two alternate simplified pain intensity scales for preschool-aged children,finding that while 3-year-olds struggle with both scales,4-year-olds demonstrate greater accuracy with the Simplified Concrete Ordinal Scale,suggesting its potential superiority over the Simplified Faces Pain Scale. [16]
Von Baeyer was born in Zurich,Switzerland;his family emigrated to Canada when he was one year old. He is a descendant of Johann Jacob Baeyer,a German geodesist,and of his son,Adolf von Baeyer,who was awarded the Nobel Prize in Chemistry in 1905. He is a brother of Hans Christian von Baeyer,a science writer and Chancellor Professor of Physics at the College of William and Mary. [18]
Pain is a distressing feeling often caused by intense or damaging stimuli. The International Association for the Study of Pain defines pain as "an unpleasant sensory and emotional experience associated with,or resembling that associated with,actual or potential tissue damage."
Palliative care is an interdisciplinary medical caregiving approach aimed at optimizing quality of life and mitigating suffering among people with serious,complex,and often terminal illnesses. Within the published literature,many definitions of palliative care exist. The World Health Organization (WHO) describes palliative care as "an approach that improves the quality of life of patients and their families facing the problems associated with life-threatening illness,through the prevention and relief of suffering by means of early identification and impeccable assessment and treatment of pain,illnesses including other problems whether physical,psychosocial,and spiritual". In the past,palliative care was a disease specific approach,but today the WHO takes a broader patient-centered approach that suggests that the principles of palliative care should be applied as early as possible to any chronic and ultimately fatal illness. This shift was important because if a disease-oriented approach is followed,the needs and preferences of the patient are not fully met and aspects of care,such as pain,quality of life,and social support,as well as spiritual and emotional needs,fail to be addressed. Rather,a patient-centered model prioritizes relief of suffering and tailors care to increase the quality of life for terminally ill patients.
Pain management is an aspect of medicine and health care involving relief of pain in various dimensions,from acute and simple to chronic and challenging. Most physicians and other health professionals provide some pain control in the normal course of their practice,and for the more complex instances of pain,they also call on additional help from a specific medical specialty devoted to pain,which is called pain medicine.
Functional gastrointestinal disorders (FGID),also known as disorders of gut–brain interaction,include a number of separate idiopathic disorders which affect different parts of the gastrointestinal tract and involve visceral hypersensitivity and motility disturbances.
A pain scale measures a patient's pain intensity or other features. Pain scales are a common communication tool in medical contexts,and are used in a variety of medical settings. Pain scales are a necessity to assist with better assessment of pain and patient screening. Pain measurements help determine the severity,type,and duration of the pain,and are used to make an accurate diagnosis,determine a treatment plan,and evaluate the effectiveness of treatment. Pain scales are based on trust,cartoons (behavioral),or imaginary data,and are available for neonates,infants,children,adolescents,adults,seniors,and persons whose communication is impaired. Pain assessments are often regarded as "the 5th vital sign".
Patrick J. McGrath,OC,FRSC FCAHS is a Canadian psychologist noted for his contribution to research on childhood pain.
The visual analogue scale (VAS) is a psychometric response scale that can be used in questionnaires. It is a measurement instrument for subjective characteristics or attitudes that cannot be directly measured. When responding to a VAS item,respondents specify their level of agreement to a statement by indicating a position along a continuous line between two end points.
The Pediatric Attention Disorders Diagnostic Screener (PADDS),created by Dr. Thomas K. Pedigo and Kenneth L. Pedigo,is a suite of computer administered neuropsychological tests of attention and executive functioning. The PADDS is used in the diagnosis of attention deficit hyperactivity disorder (ADHD) in children between the ages of 6 and 12 years. The PADDS software program represents a multi-dimensional,evidence-based approach to ADHD assessment,consisting of the Computer Administered Diagnostic Interview (CADI),the Swanson,Nolan,and Pelham—IV (SNAP-IV) Parent and Teacher rating scales,and the three computer-administered objective measures of the Target Tests of Executive Functioning (TTEF). It calculates a diagnostic likelihood ratio,where each data source is allowed to contribute to (or detract from) the prediction of the diagnosis,as well as normalized relative standard scores,t-scores,z-scores,and percentile ranks for comparison to the non-clinical reference group.
Pediatric psychology is a multidisciplinary field of both scientific research and clinical practice which attempts to address the psychological aspects of illness,injury,and the promotion of health behaviors in children,adolescents,and families in a pediatric health setting. Psychological issues are addressed in a developmental framework and emphasize the dynamic relationships which exist between children,their families,and the health delivery system as a whole.
Abdominal migraine(AM) is a functional disorder that usually manifests in childhood and adolescence,without a clear pathologic mechanism or biochemical irregularity. Children frequently experience sporadic episodes of excruciating central abdominal pain accompanied by migrainous symptoms like nausea,vomiting,severe headaches,and general pallor. Abdominal migraine can be diagnosed based on clinical criteria and the exclusion of other disorders.
The Patient-Reported Outcomes Measurement Information System (PROMIS) provides clinicians and researchers access to reliable,valid,and flexible measures of health status that assess physical,mental,and social well–being from the patient perspective. PROMIS measures are standardized,allowing for assessment of many patient-reported outcome domains—including pain,fatigue,emotional distress,physical functioning and social role participation—based on common metrics that allow for comparisons across domains,across chronic diseases,and with the general population. Further,PROMIS tools allow for computer adaptive testing,efficiently achieving precise measurement of health status domains with few items. There are PROMIS measures for both adults and children. PROMIS was established in 2004 with funding from the National Institutes of Health (NIH) as one of the initiatives of the NIH Roadmap for Medical Research.
Pain catastrophizing is the tendency to describe a pain experience in more exaggerated terms than the average person,to ruminate on it more,and/or to feel more helpless about the experience. People who report a large number of such thoughts during a pain experience are more likely to rate the pain as more intense than those who report fewer such thoughts.
Catastrophic thinking has widely been recognized in the development and maintenance of hypochondriasis and anxiety disorders. This broadly accepted understanding has classified catastrophizing as a tendency to misinterpret and exaggerate situations that may be threatening. Pain is an undesirable sensory and emotional experience in response to potential or actual tissue damage. A general consensus of pain catastrophizing involves an exaggerated negative perception to painful stimuli. The components of catastrophizing that are considered primary were long under debate until the development of the Pain Catastrophizing Scale (PCS) by Michael J. L. Sullivan and Scott R. Bishop of Dalhousie University in 1995. The PCS is a 13 item scale,with each item rated on a 5-point scale:0 to 4. The PCS is broken into three subscales being magnification,rumination,and helplessness. The scale was developed as a self-report measurement tool that provided a valid index of catastrophizing in clinical and non-clinical populations. The results of the initial development and validation studies,performed by Sullivan and Bishop,indicated that the PCS is a reliable and valid measurement tool for catastrophizing,according to Sullivan and Bishop. The high test-retest relationships concluded that individuals may possess enduring beliefs with regards to the threat value of painful stimuli. It was also found that from a clinical perspective,the PCS may be useful in identifying individuals that may be more susceptible to high distress responses from aversive medical procedures such as chemotherapy or surgery.
The Children's Depression Inventory is a psychological assessment that rates the severity of symptoms related to depression or dysthymic disorder in children and adolescents. The CDI is a 27-item scale that is self-rated and symptom-oriented. The assessment is now in its second edition. The 27 items on the assessment are grouped into five major factor areas. Clients rate themselves based on how they feel and think,with each statement being identified with a rating from 0 to 2. The CDI was developed by American clinical psychologist Maria Kovacs,PhD,and was published in 1979. It was developed by using the Beck Depression Inventory (BDI) of 1967 for adults as a model. The CDI is a widely used and accepted assessment for the severity of depressive symptoms in children and youth,with high reliability. It also has a well-established validity using a variety of different techniques,and good psychometric properties. The CDI is a "Level B test," which means that the test is somewhat complex to administer and score,with the administrator requiring training.
The General Behavior Inventory (GBI) is a 73-question psychological self-report assessment tool designed by Richard Depue and colleagues to identify the presence and severity of manic and depressive moods in adults,as well as to assess for cyclothymia. It is one of the most widely used psychometric tests for measuring the severity of bipolar disorder and the fluctuation of symptoms over time. The GBI is intended to be administered for adult populations;however,it has been adapted into versions that allow for juvenile populations,as well as a short version that allows for it to be used as a screening test.
Childhood chronic pain affects at least 5% of the population under the age of 18,according to conservative epidemiological studies. Rates of pediatric chronic pain have also increased in the past 20 years. While chronic pain conditions vary significantly in severity,they often affect children's mental health,academic performance,activities of daily living,social participation,and general quality of life. The outcomes of childhood chronic pain are affected by a number of factors,including demographic factors,genetics,access to rehabilitation services,and school and family support.
Pain management in children is the assessment and treatment of pain in infants and children.
