INFORMATIONThose without access to this information are
increasingly becoming isolated. We live in a digital world.

DEFINING INFORMATION QUALITY
People need the right information at the right time for the right purpose.

DEFINING INFORMATION QUALITY
What is meant by these quality dimensions?
Information quality is complex, Multidimensional and has human involvement
Fit for purpose

DEFINITION OF INFORMATION QUALITY
• The right information means that it must have:-

ONLINE ENVIRONMENT & CONTEXT The online environment The information producer & consumer -in a specific context. The information needs of these people need to be
considered.
So much information!
So many choices!
What does it all mean?
![Page 11: Retha de la Harpe Associate Professor Faculty Informatics & Design](https://reader036.vdocuments.pub/reader036/viewer/2022070421/56815ff8550346895dcef7af/html5/thumbnails/11.jpg)
INFORMATION CONTEXT
In community-based contexts, information intermediaries often provide information to individuals from communities with a low literacy level.
![Page 12: Retha de la Harpe Associate Professor Faculty Informatics & Design](https://reader036.vdocuments.pub/reader036/viewer/2022070421/56815ff8550346895dcef7af/html5/thumbnails/12.jpg)
INFORMATION INTERMEDIARIES The information intermediaries typically convey
information on an informal basis, via face-to-face meetings, focus groups, or discussions.
This could result in information degradation over time, or prove inadequate for sharing and public dissemination.
![Page 13: Retha de la Harpe Associate Professor Faculty Informatics & Design](https://reader036.vdocuments.pub/reader036/viewer/2022070421/56815ff8550346895dcef7af/html5/thumbnails/13.jpg)
COMMUNITY BASED CONTEXTS HEALTH INTERMEDIARIES
• There is emphasis today on wellbeing through health promotion and disease prevention.
• More individuals obtain relevant information to enable them manage their own lifestyles.
![Page 14: Retha de la Harpe Associate Professor Faculty Informatics & Design](https://reader036.vdocuments.pub/reader036/viewer/2022070421/56815ff8550346895dcef7af/html5/thumbnails/14.jpg)
COMMUNITY BASED CONTEXTS HEALTH INTERMEDIARIES
In community-based contexts health intermediaries take on the role as information consumers to convey relevant information to the individuals.
Even in these cases the health intermediaries may also not have easy access to relevant information.

MOBILE TECHNOLOGY IN THE GLOBAL SOUTH
The context of ubiquitous mobile technology in the Global South Community-oriented information systems Granting universal access – but is this enough?

What is eHealth literacy?
Defined as the ability to
seek, find, understand and appraise health information from electronic sources
and apply the knowledge gained to addressing or solving a health problem.
Unlike other distinct forms of literacy, eHealth literacy combines facets of literacy skills and
applies them to eHealth promotion and care.
WHO, 2013

Reaching poor communities• A mobile library and resource centre for outreach to
support rural schools, early childhood care centres and adult education
• Poor communities - rural and urban communities where people are trapped in a perpetual cycle of poverty and unemployment with the appalling social ills such as… substance abuse, family violence, child abuse, disease and crime … amongst others. A mobile library goes out to rural primary schools to improve the reading literacy rates.

Health Information LiteracyAn Asset
• For individuals & communities
• Important form of social capital
• and means empowerment

The story of a Health IntermediaryHealth promoter: David
• Completed his Matric; works for NPO in a high-transmission area
• Distributes promotional health materials (condoms, pamphlets)
• A lot of tense discussions with community members, especially medical male circumcision, unprotected sex, and condom use
• Uses paper-based promotional materials; wishes these were more colourful and interactive
• He owns a feature mobile phone and uses a pay-as-you-go option. He has limited money available to buy more airtime

Context considerations to design mHealth Solutions
Four intersecting dimensions of context– Personal (micro)
– Physical (meso)
– Socio-economic (macro)
– Interactional (dynamic)
![Page 21: Retha de la Harpe Associate Professor Faculty Informatics & Design](https://reader036.vdocuments.pub/reader036/viewer/2022070421/56815ff8550346895dcef7af/html5/thumbnails/21.jpg)
Context Information need
Personal (micro) Locally defined information about treatment, prevention, and promotion.
Physical (meso) Information that supports the services provided, including health facilities, resources, services, partners, and training opportunities in the region.
Socio-economic (macro) Information about guidelines, policies, international best practices, and laws.
Interactional (dynamic) Information practices; information seeking and behaviour of individuals and groups; experiences when interacting with information objects and with mobile devices, systems or applications.
![Page 22: Retha de la Harpe Associate Professor Faculty Informatics & Design](https://reader036.vdocuments.pub/reader036/viewer/2022070421/56815ff8550346895dcef7af/html5/thumbnails/22.jpg)
mHealth Intermediary Information Model
• Health intermediaries need information to support their work practices;
• Currently, the vast amount of health information is not always accessible and locally relevant;
• An intervention may be needed to facilitate the access and use of relevant health information for intermediaries. mHealth has the potential to facilitate this;
• Intermediaries’ work practices are influenced by the contexts in which they function;
![Page 23: Retha de la Harpe Associate Professor Faculty Informatics & Design](https://reader036.vdocuments.pub/reader036/viewer/2022070421/56815ff8550346895dcef7af/html5/thumbnails/23.jpg)
mHealth Intermediary Information Model
• Contextual aspects are complex and need to be unpacked to provide for possible information interventions;
• Contexts manifest as both static and dynamic modalities. Example, availability of a phone (static) against using the phone to seek and use information (dynamic).
• In designing mobile interventions, both static and dynamic context considerations are required.

Two contextual design considerations
1. Determine the static context dimensions across three levels: personal (subjective, experiential realms) physical (temporal, spatial, material realms) macro (geographic and socio-economic realms)
2. Determine the dynamic information space in terms of information practices Relations user experiences (the ‘fourth context’)
This concerns the interaction between intermediaries and recipients, especially related to information practices, objects and behaviour.
