An evolutionary-based model of health and viability

Area of Science:

• Psychology
• Evolutionary Biology
• Sociology

Background:

• Health and viability are influenced by numerous psychosocial variables.
• Illness and death can serve an evolutionary function, enhancing group natural selection.
• Social context and individual contribution to social networks are critical for health.

Purpose of the Study:

• To present a comprehensive model of health and viability.
• To integrate psychosocial factors, evolutionary principles, and social context into a health model.
• To highlight the role of clinical practice and nursing in restoring patient viability.

Main Methods:

• Conceptual model development integrating psychosocial variables.
• Analysis of evolutionary functions of illness and death.
• Examination of social context's impact on health and viability.

Main Results:

• Evolutionary viability, defined by social network contribution, is a crucial health determinant.
• Life events, lifestyle, control perceptions, and viability emotions are key components of the model.
• The model suggests a need for clinical interventions focused on enhancing patient viability.

Conclusions:

• Restoring a sense of viability is essential in clinical practice.
• Nursing, with its interpersonal focus, is well-positioned to address patient viability needs.
• A psychosocial-evolutionary framework offers new perspectives on health and well-being.
