8: Theory-Driven Public Health Interventions Flashcards
What is an intervention
An intervention is a deliberate and planned action or set of actions aimed at bringing about a change in a specific behavior, condition, or outcome.
What are theory-driven approaches to intervention design
Theory-driven approaches involve using established theories or models to guide the design and development of interventions. These theories provide a framework for understanding behavior and identifying effective strategies for behavior change
What are the key principles of a complex intervention
- Addressing multiple levels
- Adapting to context
- Iterative development
- Fidelity and flexibility
What are some mobile technologies that can be used for interventions
Mobile applications (apps)
SMS (Short Message Service)
Wearable devices
Telehealth and video conferencing
What are the advantages of mobile technologies for interventions
- Wide reach
- Convenience
- Real-time data collection
What are the disadvantages of mobile technologies for interventions
- Access and equity
- Reliance on technology
- Privacy and security concerns
What are the study designs for evaluating interventions
Randomized Controlled Trials (RCTs)
Quasi-experimental designs
Pre-post designs
Observational studies
How to design your own public health intervention
- Identify the problem
- Conduct a needs assessment
- Set objectives and goals
- Select theoretical frameworks
- Develop intervention components
- Pilot and refine
- Implement and evaluate
- Disseminate and scale up
What is a logic model
A logic model is a systematic and visual representation of the relationships among the resources, activities, outputs, and outcomes of a program, project, or intervention.
What are the components of a logic model
Inputs: Resources and materials required for the intervention.
Activities: Specific actions and processes carried out as part of the intervention.
Outputs: Direct products or services resulting from the activities.
Outcomes: Changes or results expected from the intervention.
Assumptions: Underlying beliefs or hypotheses about how the intervention will work.
External Factors: Contextual influences that may affect the intervention’s implementation or outcomes.
What are the benefits of using logic models
Clarity and Focus: Provides a clear understanding of intervention goals and activities.
Alignment: Ensures objectives, strategies, and outcomes are aligned.
Communication: Facilitates communication among stakeholders.
Evaluation and Monitoring: Helps plan and conduct evaluations.
Learning and Improvement: Identifies areas for improvement in the intervention design and implementation.
What are the steps for developing a logic model
Identify the Purpose: Determine why you need a logic model and clarify goals.
Engage Stakeholders: Involve key stakeholders in the development process.
Define Components: Determine inputs, activities, outputs, outcomes, assumptions, and external factors.
Establish Relationships: Identify causal relationships between the components.
Use Visual Representation: Create a visual diagram or flowchart.
Refine and Validate: Review the logic model with stakeholders and make revisions.
Utilize and Update: Apply the logic model for planning, implementation, and evaluation.
What are multilevel interventions
Multilevel interventions recognize that people’s behavior is influenced by both individual characteristics and the larger contexts they live in. They target change at multiple levels simultaneously to create lasting behavior change.
What is intervention evaluation
Intervention evaluation is a framework used to develop and assess the effectiveness of complex interventions. It involves process evaluation, feasibility study, pilot study, and randomized controlled trials (RCTs).
