Lehman Biopsychosocial Model

Introduction

  • The article by Lehman, David, and Gruber explores the biopsychosocial model of health.

  • The authors propose a dynamic biopsychosocial model that integrates systems theories from developmental scholars.

  • The focus is on how biological, psychological, interpersonal, and contextual factors interact over time to shape health.

Dynamic Biopsychosocial Model

  • Conceptual Roots: Expands on Engel's biopsychosocial model (1980) integrating Bronfenbrenner's heirarchical ecological models and Sameroff's transactional model.

  • Reciprocal Influences: Health is influenced by the reciprocal interactions of various factors across personal and historical time.

Components of the Model

Biological Dynamics

  • Physical Influences: Key biological systems include immune and cardiovascular systems.

  • Interconnected Systems: Biological dynamics interact with social and psychological factors.

  • Gene-Environment Interactions: Advances in the understanding of gene-environment interactions and epigenetics contribute to health outcomes.

Psychological Dynamics

  • Mental Health Factors: Encompasses cognitive, emotional, motivational, and behavioral factors influenced by identity and coping strategies.

  • Self-Systems: Literature suggests self and identity should be considered systems in health psychology.

Interpersonal Dynamics

  • Direct and Indirect Influences: Considers actual and perceived social contacts and their impact on health.

  • Complex Relationships: Recognizes the complexity of interpersonal factors and their dynamic characteristics over time.

  • System Examples: Friendship networks and peer influences on health behaviors among youth are examples of interpersonal dynamics.

Contextual Dynamics

  • Cultural Influences: Includes societal norms, values, and policies that shape interpersonal and psychological factors.

  • Example: Legislative changes reflecting cultural shifts (e.g., same-sex marriage laws) potentially impact public health behaviors and understandings.

Centrality and Time

  • Concept of Centrality: The relevance of various dynamics fluctuates over time, affecting health impacts.

  • Dynamic Changes: Factors like parental relationships and social influences are not static and change throughout an individual's life cycle.

Case Studies

Brandon's Example

  • Background: A white male from a middle-class family struggling with ADHD.

  • Impact of Family Dynamics: Influences of parenting styles lead to emotional regulation issues.

  • Health Outcomes: Brandon's ongoing struggles with behavior and relationships due to his upbringing and neighborhood environment.

  • Resolution: Mentorship and supportive relationships help improve Brandon’s health and coping mechanisms over time.

Evette's Example

  • Background: An Alaska Native woman from a rural community facing high rates of substance abuse and mental health issues.

  • Influences on Health: Historical trauma and cultural challenges coupled with family dynamics contribute to her depression and obesity.

  • Support Systems: Community and cultural connections play a crucial role in her recovery journey.

Implications and Conclusions

  • Mentorship Importance: Highlighted as a potential intervention for at-risk youth health outcomes.

  • Cultural Competence in Health Care: Need for culturally sensitive approaches within health services to improve minority health.

  • Future Research Directions: Utilizing dynamic biopsychosocial perspectives for evaluating health determinants and policies that include social network dynamics and environmental influences.
