Background & History of Ecologic Models Application of Ecological Models to Health BehaviorGuiding Principles of Ecologic Models Types of Ecologic ModelDEFINITION OF TERMS

ECOLOGIC MODEL- Provide comprehensive frameworks forunderstanding the multiple and interactingdeterminants of health behavior.

BACKGROUND & HISTORY OF ECOLOGIC MODELS Ecology Based on a rich conceptual tradition in the behavioral sciences Accdg. to Stokols (1992), ecologic models focus on the nature of peoples transactions with their physical and socio-cultural surroundings.

GUIDING PRINCIPLES OF ECOLOGIC MODEL

4 Principles of Ecologic Model

1.2.3.4.Multiple levels of factors influence perspectives are proposed.

Influences interact across levels Multi-level interventions should be most effective in changing behavior Ecological models are most powerful when they are behavior-specific

TYPES OF ECOLOGIC MODEL

TYPES OF ECOLOGIC MODEL

1. Clark-Leavell Triad Model There are three interactive factors that affect health and illness

2. Lever Model

AGENTAENVIRONMENTHOST Used to show the relationship between the host, agent and environment

5. Rothmans Pie A cause of a disease is an event, condition, or characteristics that plays an essential role in producing an occurrence of the disease
