Studying group differences
___________________________: Do test scores change, following an experimental manipulation, in the direction predicted by the theory underlying the construct?

_________________________: Does the test have high correlations with measures of the same and related traits (convergent validity) and low correlations with measures of unrelated traits (discriminant validity)?
Assessing the test’s convergent and discriminant validity
_______________: Does the test have the factorial composition it would be expected to have — i.e., does it have factorial validity?
Assessing the test’s factorial validity
Construct validity is said to be the most ____-____ of the methods of test validation. The developer of a test designed to measure a construct begins with a ____ about the ____ of the ____, which then guides the test developer in ____ ____ ____ and in choosing the ____ for ____ the ____ ____. If the developer of a creativity test believes that creativity is unrelated to general intelligence, that creativity is an innate characteristic that cannot be learned, and that creative people can be expected to generate more alternative solutions to certain types of problems than non-creative people, she would want to determine the correlation between scores on the creativity test and a measure of intelligence, see if a course in creativity affects test scores, and find out if test scores distinguish between people who differ in the number of solutions they generate to relevant problems.

The ____-____ ____ (Campbell & Fiske, 1959) is used to systematically organize the data collected when assessing a test’s convergent and discriminant validity. The multitrait-multimethod matrix is a ____ of ____ ____, and, as its name suggests, it provides information about the ____ of ____ between ____ or ____ ____ that have each been assessed using ____ or ____ ____. When the correlations between different methods measuring the same trait are larger than the correlations between the same and different methods measuring different traits, the matrix provides evidence of the test’s ____ and ____ ____.

Heterotrait-Heteromethod Coefficients; Discriminant Validity; Small
Note that, in a multitrait-multimethod matrix, only those correlation coefficients that include the test that is being ____ are of ____. For the above example, the correlation between the assertiveness rating and the aggressiveness rating (r = .16) is a heterotrait-monomethod coefficient, but it isn’t of interest because it doesn’t provide information about the assertiveness test. Also, the number of correlation coefficients that can provide evidence of convergent and discriminant validity depends on the ____ of ____ ____ in the ____. In the example, only four measures were included (the minimum number), but there could have been more.
Validated; Interest; Number of Measures Included; Matrix
Example: Three of the correlation coefficients in the above multitrait-multimethod matrix are relevant to the construct validity of the assertiveness test. The correlation between the assertiveness test and the assertiveness rating (monotrait-heteromethod coefficient) is .71. Since this is a relatively high correlation, it suggests that the test has ____ ____. The correlation between the assertiveness test and the aggressiveness test (heterotrait-monomethod coefficient) is .13 and the correlation between the assertiveness test and the aggressiveness rating (heterotrait-heteromethod coefficient) is .04. Because these two correlations are low, they confirm that the assertiveness test has ____ ____. This pattern of correlation coefficients confirms that the assertiveness test has ____ ____. Note that the monotrait-monomethod coefficient for the assertiveness test is .93, which indicates that the test also has adequate reliability. (The other correlations in the matrix are not relevant to the psychologist’s validation study because they do not include the assertiveness test.)
Convergent Validity; Discriminant Validity; Construct Validity
In the context of the multitrait-multimethod matrix, “mono” means same and “hetero” means ____. Keeping this in mind will help you “translate” the names of the correlation coefficients contained in the matrix: For example, a heterotrait-monomethod coefficient indicates the correlation between two different traits that have been measured with the ____ ____ of ____.

For the exam, know that convergent and discriminant validity are methods for assessing ____ ____ and be familiar with the names and Interpretations of the various types of correlation coefficients contained in a multitrait-multimethod matrix (e.g., know that a large monotrait-heteromethod coefficient provides evidence of ____ ____). It is NOT likely that you will encounter a question on the exam that resents a matrix and requires you to interpret a specific correlation coefficient or identify a particular type of coefficient.
Construct Validity; Convergent Validity
A test has construct validity when it has been shown that the test actually measures the hypothetical (1) ____ it is intended to measure. One method for assessing a test’s construct validity is to determine if the test has both (2) ____ and (3) ____ (divergent) validity. When a test has (4) ____ correlations with measures that assess the same construct, this provides evidence of the test’s (5) ____ validity; when a test has (6) ____ correlations with measures of unrelated characteristics, this indicates that the test has (7) ____ validity.

A ____ ____ is conducted to identify the minimum number of common factors (dimensions) required to account for the intercorrelations among a set of tests. subtests, or test items. The information obtained from a factor analysis is used for several reasons including assessing a test’s ____ ____. When used for this purpose, a test is considered to have construct (factorial) validity when it has ____ ____ with the factor(s) that it would be ____ to ____ ____ and ____ ____ with the factor(s) It would ____ be ____ to ____ ____. In other words, when employed as a method for assessing construct validity, factor analysis is another way to obtain information about a ____ ____ and ____ ____.
Factor Analysis; Construct Validity; High Correlations; Expected to Correlate With and Low Correlations; Not be Expected to Correlate With; Test’s Convergent and Discriminant Validity
____ ____ ____ to a ____ of ____: When using factor analysis to assess the construct validity of a test, the test is administered to a sample of examinees along with other tests, some that measure the same construct and some that measure different constructs.
Administer Several Tests to a Group of Examinees
____ ____ on ____ ____ with ____ on ____ ____ ____ to ____ a ____ (_) ____: High correlations between tests suggests that they are measuring the same construct(s), while low correlations indicate that they are measuring different constructs. It is the pattern of correlations between the tests that indicates how many factors should be “extracted” in the factor analysis.
Correlate Scores on Each Test with Scores on Every Other Test to Obtain a Correlation (R) Matrix
____ ____ of ____ ____ ____ ____, ____ the ____ ____ to a ____ ____: The data in the correlation matrix are used to derive a factor matrix. The factor matrix contains correlation coefficients (“factor loadings”), which indicate the degree of association between each test and each factor.
Using One of Several Factor Analytic Techniques, Convert the Correlation Matrix to a Factor Matrix
____ the ____ of the ____ by “____” ____: The pattern of factor loadings tn the original factor matrix is usually difficult to interpret, so the factors are “rotated” to obtain a clearer pattern of correlations. As noted below, the rotation can produce either orthogonal or oblique factors.
Simplify the Interpretation of the Factors by “Rotating” Them
____ and ____ the ____ in the ____ ____ ____: The appropriate names (labels) for the factors are determined by examining the tests that do and do not correlate with each factor. When the factor analysis is being conducted to assess a test’s construct validity, validity is demonstrated when the test has high correlations with the factor(s) it would be expected to correlate with and low correlations with the factor(s) it would not be expected to correlate with.
Interpret and Name the Factors in the Rotated Factor Matrix
Example: A psychologist decides to assess the construct validity of an interpersonal assertiveness test (Test A) by administering it to a group of salespeople along with two other measures of assertiveness (Tests B and C) and three measures of aggressiveness (Tests X, Y, and Z). The psychologist first derives a correlation matrix from the data she has collected. The correlation matrix provides her with the information she needs to determine how many factors to extract and with the data required to derive the initial factor matrix. Because the initial factor matrix is difficult to interpret, the psychologist ____ the initial factors and obtains the following rotated factor matrix:
Rotates
The numbers listed under the headings “Factor I” and “Factor Il” are ____ ____, which are correlation coefficients that indicate the degree of association between each test and each factor. One way to interpret a factor loading is to ____ ____ to determine the amount of ____ in ____ ____ that is accounted for by (explained by) the ____: The interpersonal assertiveness test (Test A) has factor loadings of .78 and .16 with Factors I and Il, respectively. This means that 61% (.782) of variability in the assertiveness test is accounted for by Factor I, while 3% (.162) is accounted for by Factor II.

The numbers in the last column of the factor matrix are the ____. Each test’s ____ indicates its “common variance,” or the amount of variability in test scores that Is due to the factors that the test shares in common, to some degree, with the other tests included in the analysis. In other words, a test’s communality indicates the ____ ____ of ____ in ____ ____ that is accounted for by ____ of the ____ ____. The communality for the interpersonal assertiveness test is .64. This means that 64% of variability in assertiveness test scores is accounted for by a combination of Factor I and Factor II.
Communalities; Communality; Total Amount of Variability in Test Scores; All of the Identified Factors
Recall that a ____ ____ indicates the amount of variability in test scores that represents true score variability.
