Sources of Personality Data:
Self-report Data (S-data): the information a person reveals through interviews,
periodic reports, and questionnaires.
2 forms of Self-report data:
Structured: the responses are set (i.e. Dichotomous [i.e., Forced-Choice, yes or no]
or Likert ratings [rate something 1-5]
Pros: - it’s standard and utilizes stats,
- Everyone understands the question and gives similar answers
Cons: - limited in responses & limited accuracy
Unstructured: the responses are not set (open ended questions)
Pros: - very detailed
- No limits in responses
Cons: - not standard so people might misinterpret the question
- Doesn’t use stats
Limitations of Self-report Data
- Honesty in responses
- Not having self-knowledge or objectivity to respond
Other s-data Approaches
- Event Sampling Ecological Momentary Assessment: Self-report that occurs
over time to assess variables that might change in ‘real-time’
Nock et al. 2009 Experiment
- Suicidal and self injury reports
- Findings: that suicidal thoughts and self injury thought have unique
differences and features, this may be helpful for treatment
