Study Notes
Reliability in Psychological Testing
- Reliability ensures consistency and reproducibility in test scores
- Test-retest reliability measures consistency over time by administering the same test to the same group.
- Interrater reliability checks for consistency in scores between different observers
- Internal consistency measures how well items within a test that are meant to assess the same construct produce similar results.
- Equivalent forms reliability evaluates if different versions of the same test produce consistent results.
Validity in Psychological Testing
- Validity assesses if a test actually measures what it claims to measure.
- A test must be reliable to be valid.
- A reliable test is not necessarily valid because a test can reliably measure the wrong construct.
Kinds of Test Validity
- Face validity refers to whether the test, on its face, appears to measure what it is intended to.
- Content validity measures if the test fully covers all aspects of the construct.
- Predictive validity assesses whether the test can predict future performance or behavior.
- Construct validity examines if the test aligns with theoretical assumptions about the construct.
Correlation Analysis
- Pearson correlation calculates the strength and direction of the relationship between two continuous variables.
- It requires data on an interval or ratio scale and both variables should be normally distributed.
- The calculation involves the covariance of the two variables.
Effect Size in Inferential Statistics
- Effect size quantifies the magnitude of a result in the population, beyond just statistical significance.
- Cohen's d measures the difference between two means in terms of standard deviations.
- The Pearson correlation coefficient (r) itself acts as the effect size for correlation analyses.
Degrees of Freedom and t Distribution
- Degrees of Freedom (df) refers to the number of independent data points free to vary.
- t Distribution is bell-shaped and accounts for more variability, particularly with smaller sample sizes.
Parametric vs Non-Parametric Tests
- Parametric tests assume data is normally distributed and measured on an interval or ratio scale.
- Non-parametric tests are used when parametric assumptions are not met.
Neuropsychological Assessment
- Clinical Neuropsychologist assess and treat individuals with brain disorders affecting cognitive functions.
- Referral Questions guide the assessment process, determining the cognitive areas to focus on.
- Cognitive Characterization, Diagnostic Opinion, Rehabilitation, Behavior Management, Psychoeducation, and Monitoring Change are core roles of a neuropsychologist.
Psychoeducational Assessment Report
- Referral Questions identify specific concerns.
- Background Information includes developmental, educational, family history, and previous interventions.
- Assessment Results summarize test scores and observations, followed by interpretations.
- Recommendations provide individualized suggestions, such as further assessments or classroom accommodations.
