    The Personalized Health Determinants Model (PHDm) expands Engel's Bio-Psycho-Social model into nine interrelated dimensions.

  • 2

    The PHDm includes Biological, Psychological, Social, Cultural, Environmental, Economic, Political, Spiritual, and Lifestyle dimensions.

  • 3

    Operationalization of the PHDm is illustrated through a case study on obesity using Bayesian Networks and rule-based scoring.

    Preliminary evaluation of the PHDm shows promising predictive accuracy but remains a proof-of-concept prototype.

    Further validation and integration into electronic health records are necessary before the PHDm can be clinically deployed.
