Question 4

Multiply strategy and Multiply setting

Answer 4

both very effective, as it can reach a large number of people in a variety of ways

Question 5

Intervention Mapping

Answer 5

Effective decision making - of each step of intervention development

planning is explicit / transparent

Question 6

Steps of intervention mapping (Kok et al.,2016)

Answer 6

1. What is the problem?
2. What is the objective / desired change? What are the determinants of the problem? Who are we targeting?
3. Identify possible intervention methods
4. Design program material / pretest material
5. Implementation of intervention
6. Monitor / evaluate, measure effects / processes

Question 7

What is the problem?

Answer 7

Check for Needs assessment or problem analysis

Needs assessment - bridge gap between individuals current and desired state

Problem analysis - asses what needs to be changed and for whom?

Question 8

What is the desired change/objective? Determinants of problem? Target population?

Answer 8

Learning objectives –> What do individuals need to learn/do?

Change objectives –> What needs to be changed in organisations / community?

• Kok et al. 2016 *
  1. Create matrices
  2. combine (sub)behaviour + behaviour interventions
  3. identify behaviour that is targeted by intervention

Question 9

Determinants

Answer 9

Factors that affect the nature of an outcome

Personal determinants - individual / cognitive factors, etc

External determinants - structural / social factors, etc.

Question 10

Identify possible intervention methods

Answer 10

How can determinants be influenced to the desired change

(Kok et al. 2016)

1. select theory based intervention –> that match determinant
2. identified beliefs bundle / translate to practical application (ex. face to face group discussions)

Question 11

Design program material / pretest material

Answer 11

(Kok et al., 2016)

integrate practical applications –> organised program

Question 12

Implementation of intervention

Answer 12

Kok et al. 2016

identify program users / supporters –> what are their needs

Question 13

Network Intervention

Answer 13

People can be influenced by their social network to adopt a new behaviour

Question 14

Network intervention uses social media to;

Answer 14

meet objectives / reach outcomes

accelerate social change

generate influence

Question 15

Network intervention strategies

Answer 15

which component of social network will be targeted

Induction

individual

segmentation

alteration

Question 16

Induction

Answer 16

generating new connections with individuals

ex. word of mouth

Question 17

Individual level

Answer 17

intervention strategies that target a specific individual in a social network

ex.

broker (bridging)

leader

nodes

Question 18

Segmentation

Answer 18

intervention strategies that target a specific group within a social network

ex.

mutually exclusive

core-periphery network

Question 19

Alteration

Answer 19

intervention strategies that change the network itself

• -> adding / deleting nodes
• -> adding / deleting ties
• -> rewriting existing ties
