Question | Answer |
What is a dimension in personality psychology? | It refers to a continuum on which an individual can have various levels of a trait. |
What are the three core questions regarding a test's dimensionality? | 1. How many dimensions are reflected in the test items? 2. If a test has more than one dimension, are those dimensions correlated with each other? 3. If a test has more than one dimension, what are those dimensions? |
What is unidimensionality? | The property of a test where the test items reflect only one psychological dimension. |
What is conceptual homogeneity? | The property of test items whereby the responses to each test item would be a function or measure of the same psychological attribute. |
How are scores computed in unidimensional tests? | Only a single score is computed, which reflects the single psychological attribute measured by the test. All the items are combined in some way to form a composite or "total" score. |
What is multidimensionality? | The property of a test where the test items reflect more than one psychological dimension. |
What are some examples of multidimensional tests with correlated dimensions? | The Weschler Intelligence Scale for Children (WISC-IV) and the Stanford-Binet (SB5) |
How do standard multidimensional tests with correlated dimensions group questions? | They have groups of questions that assess different psychological attributes called subtests. |
What are subtests? | groups of questions that assess different psychological attributes in multidimenional tests with correlated dimensions |
In the SB5, how are questions ordered? | Each subtest, proven to correlate positively with each other, measures a different facet of intelligence. 1. Fluid Reasoning 2. General Knowledge 3. Quantitative processing ability 4. Visual-Spatial processing ability 5. Working memory |
How are scores in multidimensional tests with correlated dimensions scored? | Since each subtest is unidimensional and the questions in each subtest are conceptually homogeneous, each subtest produce its own score. These scores are then combined to produce a total test score. |
What is a higher-order factor in multidimensional tests with correlated dimensions? (MTCD) | They are a factor that is at a more general level than the specific factors or attributes. |
What is the difference between unidimensional tests and MTCDs? | Unidimensional tests only need to have their one composite score psychometrically evaluated. In MTCDs, each subtest in addition to the composite score needs to be evaluated. |
What is an example of multidimensional tests with uncorrelated dimensions (MTUD)? | The NEO Five Factor Inventory, or NEO-FFI. |
How are scores in MTUDs calculated? | A score is obtained for each subtest, but these scores are not combined. Also, each of these scores are evaluated seperately for psychometric quality. |
