The aim of this review is to illustrate an innovative framework for assessing the psychosocial aspects of medical disorders within the biopsychosocial model. It is based on clinimetrics, the science of clinical measurements. It may overcome the limitations of DSM-5 in identifying highly individualized responses at the experiential, behavioral, and interpersonal levels.
A critical review of the clinimetric formulations of the biopsychosocial model in the setting of medical disease was performed. References were identified through searches from PubMed for English articles on human subjects published from January 1982 to October 2023.
Clinimetric methods of classification have been found to deserve special attention in four major areas: allostatic load (the cumulative cost of fluctuating and heightened neural or neuroendocrine responses to environmental stressors); health attitudes and behavior; persistent somatization; demoralization and irritable mood. This type of assessment, integrated with traditional psychiatric nosography, may disclose pathophysiological links and provide clinical characterizations that demarcate major prognostic and therapeutic differences among patients who otherwise seem deceptively similar because they have the same medical diagnosis. It may be of value in a number of medical situations, such as: high level of disability or compromised quality of life in relation to what is expected by disease status; delayed or partial recovery; insufficient participation in self-management and/or rehabilitation; failure to resume healthy role after convalescence; unhealthy lifestyle; high attendance of medical facilities disproportionate to detectable disease; lack of treatment adherence; illness denial.
The clinimetric approach to the assessment of key psychosocial variables may lead to unique individual profiles, that take into account both biology and biography. It may offer new opportunities for integrating psychosocial and medical perspectives.
