Lecture 2 - Social Media Interventions Flashcards
Social media intervention
Internet based intervention strategy that exploits the affordances (functions) of social media platforms to produce a change in behaviour / improvement of situations
Benefits of social media interventions
- Increase interaction with others
- More tailored, available, shared information
- Increased accessibility and widen access
- Public health surveillance
- Peer/Social/ Emotional support
- Potential influence to health policy
limitations of social media interactions
lack of reliability of information
privacy, confidentiality, data security issues
information overload
self-report
self-selection (rather than through randomisation)
high participant dropout rate
Validity
how likely an approximation of causal relation is true or false
4 types of validity (Tengstedt et al. 2018)
Statistical conclusion
internal
constructed
external
Statistical conclusion validity
2 types of mistakes
suggesting that an intervention –> has an effect when it does not
suggesting that an intervention –> has no effect when it does
Internal validity
cause and effect validity
Constructed validity
confounding
External validity
whether relationship between variables can be generalised to other groups of people, time perspectives, setting
How to choose a social platform
target group
functionality of different social media platforms
individual identity
group identity
cognitive load
interactivity
availability (presence)
Target group
generational difference in social media in frequency and preferred platforms
gender differences on social media in type of information searched up
sub-target population may need to be addressed by different methods
Functionality of different social media platforms
individual identity
Extent to which social media interventions require users to reveal their identity
high identity
low identity
Group identity
extent to which social media interventions allow users to identify themselves with a group or with each other
Benefits of group identity
peer-to-peer communication; social support
sense of belonging
network informed association
Cognitive load
The extent to which social media interventions require cognitive investments from users
Cognitive load is determined by;
complexity of information
modality of information
required input from users
Interactivity
The extent to which users can;
give feedback
start a conversation
generate content
Availability (Presence)
The extent to which users can see someone is online
sense of connectivity in real time
