Study Notes

Personality Assessment, Measurement, and Research Design

  • This material covers personality assessment, measurement, and research design.
  • Learning objectives include understanding sources of personality data, evaluation of personality measurements, and different research designs in personality.

Sources of Personality Data

  • Self-Report Data (S-Data): Information provided by the individual, such as through surveys or interviews. Individuals have a wealth of self-knowledge often unavailable to others. S-data personality tests can be either structured (using response options) or unstructured (open-ended). Limitations include potential dishonesty or lack of accurate self-awareness from the participant.

  • Observer-Report Data (O-Data): This data comes from individuals who know the person being studied, such as friends, family, or teachers. Observers have access to information unavailable to others, potentially providing insights into natural behaviors. Strengths include multiple observer perspectives (inter-rater reliability) and access to real-world behavior. Limitations involve potential bias based on the relationship with the target person. Observations can be naturalistic (in everyday settings) or artificial (in contrived situations).

  • Test-Data (T-Data): Standardized testing situations used to ascertain how various individuals react. This approach uses a standardized situation to elicit a response from participants, allowing a comparison of their reactions. Examples include Henry Murray's bridge-building test; a task with standardized parameters to elicit the behavior. Potential limitations include participants' attempts to guess the intended trait being measured, potential for researcher bias in how the task is presented. A secondary data type within this category are physiological measures (e.g., fMRI). Such measures assess biological reactions, bypassing conscious manipulation.

  • Life-Outcome Data (L-Data): Information obtained from a person's life events, activities, and outcomes. Public records like marriage or speeding tickets may provide valuable insights into personality. Recognize that life outcomes may be influenced by factors other than personality.

Issues in Personality Assessment

  • Links among different data sources are important but not perfect. All data sources have limitations. Replicating results ("triangulation") creates more robust discoveries.

Evaluation of Personality Measures

  • Reliability: The degree to which a measurement is consistent. Types include test-retest, internal consistency, and inter-rater reliability. Response sets, such as extreme responding or social desirability, can affect reliability.
  • Validity: The degree to which a measurement actually measures what it's intended to measure. Types include face validity, predictive/criterion validity, convergent validity, discriminant validity, and construct validity.
  • Generalizability: The extent to which a measure's validity applies across different contexts, situations, and groups of people.

Research Designs in Personality

  • Experimental Methods: Designed to determine causality (if one variable causes another). This involves manipulating one variable and observing its effect on another. Randomization and counterbalancing are essential to avoid bias or predetermined patterns.
  • Correlational Studies: Observe relationships between variables but do not establish causality. Correlation coefficients quantify the relationship between variables, ranging from -1.00 (inverse relationship), 0 (no relationship), to +1.00 (direct relationship). Limitations include the directionality problem and the third variable problem.
  • Case Studies: In-depth examinations of individual lives or personalities. These are useful for generating hypotheses and providing detailed insights, but results rarely generalize to broader populations.

When to Use Experimental, Correlational, and Case Study Designs

  • Each design has strengths and weaknesses. The choice depends on the research question and the goals of the study. A combination of designs provides a more complete understanding of personality.

Summary and Evaluation

  • Identifying sources of personality data is the first part of personality assessment and measurement. The quality of data and choice of research design is essential. There is no single perfect method or approach.
