  • Actuarial Assessment: An approach to evaluation characterized by the application of empirically demonstrated statistical rules as determining factor in assessors' judgement and actions
  • Mechanical Prediction: Application of computer algorithms together with statistical rules and probabilities to generate findings and recommendations

Levels of Interpretation

  • Level I: Minimal concern with intervening processes, data are primarily treated in a sampling or correlate way
  • Level II: Descriptive Generalizations, hypothetical construct, the assumption of an inner state which goes logically beyond the description of visible behavior
  • Level III: The effort to develop a coherent and inclusive theory of the individual life or a "working image" of the patient

Parties in Psychological Assessment

  • Test Author/Developer: Creates the tests or other methods of assessment
  • Test Publishers: Publish, market, sell, and control the distribution of tests
  • Test Reviewers: Prepare evaluative critiques based on the technical and practical aspects of the tests
  • Test Users: Uses the test of assessment
  • Test Takers: Those who take the tests
  • Test Sponsors: Institutions or government who contract test developers for various testing services

Assumptions About Psychological Testing and Assessment

  • Assumption 1: Psychological Traits and States Exist: Psychological traits and states are assumed to exist and can be measured
  • Assumption 2: Psychological Traits and States can be Quantified and Measured: Traits and states can be measured using tests and other methods
  • Assumption 3: Test-Related Behavior Predicts Non-Test-Related Behavior: The tasks in some tests mimic the actual behaviors that the test user is attempting to understand
  • Assumption 4: Test and Other Measurement Techniques have Strengths and Weaknesses: Competent test users understand and appreciate the limitations of the test they use
  • Assumption 5: Various Sources of Error are Part of the Assessment Process: Error refers to something that is more than expected, and it is a component of the measurement process
  • Assumption 6: Testing and Assessment can be Conducted in a Fair and Unbiased Manner: Tests are tools and can be used properly or improperly
  • Assumption 7: Testing and Assessment Benefit Society: Considering the many critical decisions that are based on testing and assessment procedures, we can readily appreciate the need for tests### Psychological Assessment
  • A field of study that focuses on the development and use of tools to measure and evaluate human behavior, abilities, and characteristics.

Reliability

  • Refers to the consistency of a test's measurements.
  • Mortality: Problems in absences in the second session (just remove the first tests of the absents).
  • Coefficient of Stability: Statistical tool used to measure reliability, e.g., Pearson R, Spearman Rho.
  • Parallel Forms/Alternate Forms Reliability: Established when at least two different versions of the test yield almost the same scores.
  • Split-Half Reliability: Obtained by correlating two pairs of scores obtained from equivalent halves of a single test administered once.
  • Internal Consistency (Inter-Item Reliability): Measures the consistency among items within the test.
  • Error: Factors that affect reliability, e.g., Carryover Effects, Practice Effect, Item Sampling.

Error

  • Carryover Effects: Happened when the test-retest interval is short, wherein the second test is influenced by the first test.
  • Practice Effect: Scores on the second session are higher due to their experience of the first session of testing.
  • Scorer Differences: The degree of agreement or consistency between two or more scorers with regard to a particular measure.

Tests

  • Power Tests: Allow test takers to attempt all items.
  • Speed Tests: Contain items of uniform level of difficulty with a time limit.
  • Criterion-Referenced Tests: Designed to provide an indication of where a test taker stands with respect to some variable or criterion.

Theories

  • Classical Test Theory: Everyone has a "true score" on a test, which is affected by random error.
  • Domain Sampling Theory: Estimates the extent to which specific sources of variation under defined conditions are contributing to the test scores.
  • Generalizability Theory: Based on the idea that a person's test scores vary from testing to testing because of the variables in the testing situations.

Item Response Theory

  • The probability that a person with X ability will be able to perform at a level of Y in a test.
  • Focuses on item difficulty.

Latent-Trait Theory

  • A system of assumption about measurement and the extent to which item measures the trait.
  • The computer is used to focus on the range of item difficulty that helps assess an individual's ability level.

Standard Error of Measurement

  • Provides an estimate of the amount of error inherent in an observed score or measurement.
  • Higher reliability, lower SEM.

Validity

  • A judgment or estimate of how well a test measures what it is supposed to measure.
  • Content Validity: Degree of representativeness and relevance of the assessment instrument to the construct being measured.
  • Criterion Validity: A judgment of how adequately a test score can be used to infer an individual's most probable standing on some measure of interest.
  • Construct Validity: Judgment about the appropriateness of inferences drawn from test scores regarding individual standing on a variable called construct.

Test Blueprint

  • A plan regarding the types of information to be covered by items, the number of items tapping each area of coverage, and so forth.

Additional Concepts

  • Factor Analysis: Designed to identify factors or specific variables that are typically attributes, characteristics, or dimensions on which people may differ.
  • Bias: Factor inherent in a test that systematically prevents accurate, impartial measurement.
  • Rating: Numerical or verbal judgment that places a person or an attribute along a continuum identified by a scale of numerical or word descriptors.
