[Personal Factors of the Bio-Psycho-Social Model (WHO): A Revised Classification by the German Society for Social Medicine and Prevention (DGSMP)].

Background: In 2010, the ICF working group of Faculty II "Applied Social Medicine and Rehabilitation" of the German Society for Social Medicine and Prevention, DGSMP proposed a classification of personal factors (PF) for the German-speaking area. Meanwhile, the International Classification of Functioning, Disability and Health (ICF) and WHO's bio-psycho-social model were increasingly integrated into the German Social Code (Book IX for Rehabilitation and Participation). It was a legislative decision that the needs assessment for the rehabilitation process must be "comprehensive".

Personal factors and their relevance for the assessment and allocation of benefits in social medicine and rehabilitation.

A broad and common understanding of the nature of Personal Factors contributes and initiates a dialogue between professionals involved in health care to gain a comprehensive perspective regarding an individual's health condition and accurately allocate social benefits and medical interventions. Personal Factors play an essential role in the International Classification of Functioning, Disability and Health (ICF) and the underlying Bio-Psycho-Social Disease Model. To date, the World Health Organisation (WHO) has not classified Personal Factors for global use despite their impact on the functioning of individuals as facilitators or barriers.
