Exam 19: The Dependent Variable: Skillfully Measuring Intended Outcomes

In which of the following methods of data collection are participants unaware of the assessment procedure, thus eliminating reactivity?

In the context of calculating estimates of reliability, _____ is a metric based on the average interitem correlations and the number of items on the measure.

In the context of using raters for obtaining assessments, interrater agreement is both necessary and sufficient for reliable assessments.

The purpose of the dependent variable is to:

No one variable can adequately operationalize a construct because some of the variance in that variable is due to other constructs and some is due to error.

The validity of a study is concerned with whether the construct being measured is the construct of interest.

For a variable X, a reliability coefficient of r_xx that equals .75 indicates that _____ of the variance in the scores is due to true differences in the level of the characteristic of interest, and that _____ is due to other factors.

It is important that the dependent variables be designed to reflect the construct designated as the effect or outcome of the independent variable.

To indicate how a participant functions normally, an assessment process should affect the characteristics of the participant directly.

Method variance appears in counseling research when various aspects of counseling are rated from different perspectives.

Which of the following is true of reliability?

In the context of procedural considerations of designing the dependent variable, the order of the administration of instruments can have an effect on the responses obtained.

Discriminant validity is said to exist when:

For a study to be informative, scores on the dependent measure need to be similar among the study's participants.

Mood transitioning is a general tendency to evaluate oneself negatively on all dimensions.

In the context of the methods of data collection, the rationale behind projective techniques is that:

A key disadvantage of self-reports is that they are _____.

Which of the following is mentioned under the heading "Reliability estimates" in the Methods section of a thesis?

Self-reports can be biased by a number of factors, whereas measures of physiological responses can be made directly and are often presumed to be free of bias.

In the context of measuring a construct, the degree to which obtained scores reflect the true scores for individuals is called the _____ of the scores.
