How I Will Measure Anxiety, Kindness and a Score: A PS598 Unit 4 Discussion Board Post Defining Criterion Measures

Initial Post
Four variables run through the design: which prompt a student writes to, which I control, plus three I measure, namely anxious thinking during the exam, the score itself and how kind students usually are to themselves. Only the last three need criterion measures.
For cognitive test anxiety, I will use the Cognitive Test Anxiety Scale. Cassady and Johnson (2002) developed it to measure the worry and self-deprecating thoughts that interfere with test performance, as distinct from bodily symptoms, and found that higher scores were related to lower exam performance and lower entrance exam scores among undergraduates. The cognitive focus fits my hypothesis, which predicts that self-compassion will reduce self-critical thinking rather than physical arousal. Students will complete it right after the exam, rating how they felt during it.
For baseline self-compassion, I will use the Self-Compassion Scale Short Form. Raes et al. (2011) shortened Neff's original 26-item scale to 12 items and found that the short form correlated almost perfectly with the long form and had adequate internal consistency, though they recommended the total score rather than subscale scores for short-form use. Twelve items fit the five minutes I will have in the first week of class.
For exam performance, I will use the percentage score on the first Anatomy and Physiology I unit exam, which is common to all sections and graded with an answer key.
Each measure answers a different question: what students thought during the exam, how kind they usually are to themselves and what they actually scored.
Two limits matter. Both scales are self-report, so students who want to please may underreport anxiety. And the exam score depends on preparation, which the experiment cannot control except through random assignment.
What criterion measure did you choose, and what does it miss?
Reply to Tasha
Tasha, a burnout inventory sounds right for nurses. Check, the way Raes et al. (2011) checked the self-compassion short form, whether the short form supports the subscales you plan to use.
Reply to Ryan
Ryan, I agree that grade point average is too broad for your study. Cassady and Johnson (2002) used specific exam scores, which tie the outcome to a moment.

The Purdue Global PS598 Unit 4 instructions
Unit 4 asks you to define a criterion measure for each variable in your capstone and explain why you chose it. List your variables and say which you manipulate and which you measure. For each measured variable, name the instrument, describe what it captures and cite evidence of its reliability or validity from the developers or later research. Explain how each measure fits your hypothesis and your setting, including time limits and when it will be given. Name at least two limits of your measures. Invite peers to name the limit of their own chosen measure, and in two replies suggest another measure or point out a weakness in the one the classmate chose.
Inside the PS598 Unit 4 example
The post opens by listing four variables and noting which one is manipulated. A paragraph describes the Cognitive Test Anxiety Scale, its cognitive focus and its link to exam performance, and explains why it is given right after the exam. A paragraph presents the Self-Compassion Scale Short Form, its close match to the long form and its use as a total score. A paragraph names the common unit exam as the performance measure. A highlighted line sums up what each measure answers. A paragraph names two limits, self-report bias and uncontrolled preparation. Replies discuss checking short-form subscales for a burnout inventory and using specific exam scores rather than grade point average.
PS598 Unit 4 rubric: what earns full points
Graders look for a named instrument for every measured variable, with a clear statement of what it captures and evidence of reliability or validity from a cited source. The strongest posts explain why each measure fits the hypothesis, for example why a cognitive scale suits a prediction about self-critical thoughts. Practical fit, such as time limits and timing of administration, shows planning. Naming limits honestly earns credit. Replies are graded on whether they suggest a better measure or name a real weakness. Respect for classmates' choices and correct APA references for the scale developers are expected, along with timely posting. Explaining when each measure is given shows the post has thought ahead to the procedure.
PS598 Unit 4 help: mistakes that cost points
Many posts on measures name a scale without saying what it measures or citing evidence that it works. Others pick whichever scale they have heard of most, whether or not it suits the prediction. A common mistake is using subscale scores from a short form that its authors recommend scoring only as a total. Some students forget the outcome that is not a questionnaire, such as an exam score. Before posting, check that every measured variable has an instrument, a citation for reliability or validity, a reason it fits the hypothesis and a time when it will be given, and that you name at least two limits.

PS598 Unit 4 questions, answered
What is a criterion measure?
The specific instrument or observation used to measure an outcome variable.
Why report reliability?
Because an unreliable measure adds noise and makes real effects harder to detect.
What should a reply add?
Another measure, or a weakness in the measure the classmate chose.

The PS598 Unit 4 post defining measures for test anxiety, self-compassion and exam scores is above, with replies.
Why is the anxiety scale given after the exam in the PS598 Unit 4 sample?
So students rate how they felt during the exam itself, without being prompted to focus on anxiety just before testing.
