Content analysis is an indirect observational method used to analysehuman behaviour. This often produces qualitative data (written words or transcripts). This is then transformed into quantitative data.
Steps to perform a content analysis:
Decide a research question.
Select a sample (eg randomly / systematically) from a larger quantity of all possible data (eg diary entries / children's books).
Coding - Researcher decides on categories / coding units to be recorded (eg occurrences of particular words), these are based on the research question.
Work through data - Read the sample and tally the number of times the pre-determined categories appear.
Data analysis - Can be performed on quantitative data to look for patterns.
Coding units must be completely operationalised, meaning they are defined as clearly as possible.
Testing for reliability and consistency:
Test-retest. Run the content analysis again on the same sample and compare the two sets of data.
Inter-rater reliability. A second observer also performs the content analysis with the same data sets and behavioural categories. These would then be compared.
A correlation would then be conducted to test how closely related the variables are.
Strengths of content analysis:
High external validity - The 'artefacts' used are not solely created for the research but have rather been taken from the real world, allowing findings to be gerneralised.
Strengths of content analysis:
Replicable - Procedures are very clear and tend to be standardised. The categories within are also operationalised, allowing a very clear set of instructions that can be followed.
Limitations of content analysis:
Researcher / observerbias - They may interpret the text in a way supporting their pre-existing views, meaning the study may lack validity.
Limitations of content analysis:
Lacks validity - Data was not collected under controlled conditions, meaning it may lack validity. For example, written historical records (eg diaries) may not contain an accurate record of the past.
Thematic analysis is when researchers start attempting to identify deeper meanings of the text by allowing themes to emerge.
Performing a thematic analysis:
Collect text / recordings into text through transcription.
Read text / transcripts fist to spot patterns that can be coded and collected.
Re-read transcripts to look for emergent themes.
Strengths of thematic analysis:
This stops the research imposing their own bias on the analysis (by only looking for what they want to see), as they looks for general themes that emerge.
