Glanz & Rimer - Part 1 Flashcards
Theory
Presents a systematic way of understanding events or situations. It is a set of concepts, definitions, and propositions that explain or predict these events or situations by illustrating the relationships between variables. Theories are broad and abstract.
Concepts
The building blocks of a theory
Constructs
Concepts developed or adapted for use in a particular theory
Variables
The operational forms of constructs. They define the way a construct is to be measured in a specific situation.
Models
They draw on a number of theories to help understand a particular problem in a certain setting or context.
Conceptual framework/theoretical framework
Theories that are not highly developed or have not been rigorously tested.
Explanatory theory
Describes the reasons why a problem exists
Examples of explanatory theories
The health belief model, the theory of planned behavior, and the precaution adoption process model.
Change theory
Guides the development of health interventions
Examples of change theories
Community organization and diffusion of innovation’s
What are characteristics of a useful theory?
Logical, consistent with every day observations, similar to those used in previous successful programs, and supported by past research in the same area or related ideas.
Ecological perspective
Emphasizes the interaction between, and the interdependence of, factors within and across all levels of a health problem. It highlights peoples interactions with their physical and socio-cultural environments.
Two key concepts of the ecological perspective?
Behaviour affects, and is affected by, multiple levels of influence. And, individual behaviour both shapes, and is shaped by, the social environment (called reciprocal causation).
Five levels of influence for health related behaviours and conditions (ecological perspective)
Intra-personal or individual factors. Interpersonal factors. Institutional or organizational factors. Community factors. Public policy factors.
Intra-personal level (ecological perspective)
Individual characteristics that influence behavior, such as knowledge, attitudes, beliefs, and personal traits.
