Study Notes
Introduction to Psych Assessment
- Begins with a foundational understanding of psychological assessments.
- Emphasizes the importance and purpose of psych testing in various contexts.
What Makes a Good Test
- Good tests are reliable, valid, and practical.
- Their ability to measure what they are intended to measure is crucial.
Reliability and Validity
- Error is always present in psychological assessments; minimizing it is key.
- Classical Test Theory (CTT) posits that an individual's observed score consists of their true score plus error.
- True scores are unknown, but the goal is to reduce errors to be close to those true scores.
Types of Error
- Random Error: Unpredictable and can affect scores variably.
- Systematic Error: Predictable and constant; can be accounted for.
Error Variance
- Standard Error of Measurement: Indicates the extent of deviation of an observed score from the true score.
- Standard Error of the Mean: Measures sampling error by comparing samples.
- Standard Error of the Score: Reflects how one person’s scores vary over parallel tests.
- Standard Error of the Difference: Assesses how significant a score difference must be.
Reliability Coefficient
- Evaluates the variance of true scores and error scores.
- Variance indicates how scores differ, often illustrated using standard deviations.
Internal Consistency
- Internal consistency tests measure reliability within assessments.
- Cronbach's Alpha evaluates internal consistency; understanding its limitations is essential.
Test Development
- Focus on developing assessments that accurately capture the entire construct intended for measurement.
- Understanding various methods and approaches for creating reliable and valid tests is critical.
