Help phase Flashcards
What are the criteria for selecting the variable for intervention? (2)
- Is the variable modifiable
- Does it have the greatest effect on the outcome variable?
Which types of variables are excluded for an intervention? (6)
- Personality traits
- Political/religious
- Stable environmental conditions
- medical/psychiatric conditions
- Lack of intelligence and/or literacy
- Strong biological basis
What is described about the variables in the balance table (2)?
- the extent to which a variable is modifiable
- The expected effect on the outcome cariable
What are the 3 main tasks of developing an intervention?
- Selecting the right channel
- Selecting the appropriate method
- Selecting the strategy
What does ‘channel’ mean in creating an intervention?
The way how the target group members are being reached (e.g., sticker, leaflet, counseling)
What does ‘method’ mean in creating an intervention?
How will changes be brought about? e.g., persuading with arguments, proving information, using role-models
What does ‘strategy’ mean in creating an intervention?
How is the method translated to a specific context. Example; role-model; what will he or she do or don’t do.
What should be considered in selecting the right channel for an intervention? (4)
- Effectiveness (do you reach target group)
- Intensity (is exposure via this channel intensive enough for change)
- Appropriateness (is the channel appropriate for method and strategy)
- Impact (participation rate * effectiveness)
What is modeling?
learning through the observation of others
What is enactive learning?
learning a skill by trying to accomplish it yourself
What is differential reinforcement?
- undesired behavior is no longer rewarded
- Desired alternative behavior is rewarded
What is the divergent phase of intervention formulating?
Listing as many applications as possible
What is the convergent phase of intervention formulating?
Critical evaluation of the mentioned interventions in the divergent phase
What are the 6 techniques to generate applications for interventions?
- Direct intervention association
- Direct method approach
- Debilitating strategies
- Interviews
- Insights from theory
- Insights from research
Divergent phase: direct intervention association
free association based on all sources what makes intuitively sense
Divergent phase: direct method approach
looking at applications that have been used in similar conditions?
Divergent phase: debilitating strategies
Come ups with applications that have undesired effects on the problem
Divergent phase: interviews
Interviewing people from the target group
What are assessment methods used in pre-testing an intervention? (5)
- Interview
- Quantitative assessment (questionnaire)
- Recall (what u remember)
- Observation
- Expert opinions
What are the 4 phases of the diffusion process used in the implementation of new, large-scale interventions?
- Dissemination phase
- Adoption phase
- Implementation phase
- Continuation phase
What is the dissemination phase in the diffusion process?
How is the intervention being distributed and what members of an eco-system should be informed?
– rating awareness among executers
What is the adoption phase in the diffusion process?
In this phase people become motivated to use the innovation. Theys should be made aware of at least 2 things: the value of their action; the easiness of undertaking such action
– motivating executers to perform an action and support them in actual execution
What is the implementation phase of the diffusion process?
Engaging in behavior that allows for even better exposure to the target group
– providing feedback and reinforcement
What is the continuation phase of the diffusion process?
Accepting the intervention as the new normal
In which phases are executers of the intervention positively reinforced?
Adoption and implementation phase
What are the 3 components of treatment fidelity in interventions?
- Delivery - offered as intended?
- Receipt - received/understood as intended?
- Enactment - are strategies used as intended?
Why is treatment fidelity crucial (3) in intervention development?
- If intervention is effective, you want to know if it was because of program
- If intervention is ineffective, you want to know if it was because of implementation or the intervention itself?
- If fidelity is low, it causes noise in your study design and you will need a much bigger number of participants
