Using
Manifest and Latent Content Analysis

Why do content analysis?
•
Identify content and framing of communication
•
Disclose differences in communication content between individuals,
groups, institutions or societies
•
Audit communication content against objectives
•
Describe trends in the content or framing of messages over time
•
Indicate pertinent features such as comprehensiveness of coverage
•
Detect the existence of propaganda, prejudices or intentions of
authors
•
Provide an empirical basis for monitoring shifts in public opinion and
making inferences about the effects of communication on public
opinion / behaviour- see case studies

qualitative
Latent analysis
hidden meaning
Manifest content analysis: One Definition
“a research technique for the objective, systematic, and
quantitative description of manifest content of
communications"
(Berelson, 1952)
MRC/CSO Social and Public Health Sciences Unit, University of Glasgow.
Manifest content analysis
Features
• Content is inherent in the text
• Messages are quantifiable using a systematic approach
• Measured objectively
(aim to limit the subjectivity)
• A message has but one content, all other meanings
being deviant, wrong or subjective- hence excluded
• Reductionist approach with its roots in the positivism
paradigm (establishing and discovering objective facts)

Manifest coding frame

Latent content analysis: One Definition
“a research method that uses a set of procedures to make
inferences about the sender(s) of the message, the
message itself, or the audience of the message”
(Weber, 1990)
MRC/CSO Social and Public Health Sciences Unit, University of Glasgow.
Latent content analysis
Features
• The meaning of the message only emerges with
interpretation (high level of interpretation)
• A message may have different meanings
• A message is socially constructed
• Roots are in the constructivist paradigm
constructed not discovered from the world)

Could content analysis be used to analyse
dynamic social media data? If so how?
