Example of Assessing Validity via Correlation Matrix

When using correlational research to evaluate the validity of a new psychological measurement by comparing it to an established test, the new measurement is classified as the independent variable.

A researcher develops a new 10-item shyness questionnaire and administers it alongside a well-established 50-item shyness scale to 200 participants. She then calculates the correlation between participants' scores on the two measures and finds a strong positive correlation. What does this strong positive correlation suggest about the new 10-item questionnaire?

A research team is developing a new assessment tool for 'Academic Persistence.' Match the methodological goal they are trying to achieve with the specific way they would use correlation in their study.

A psychologist has developed a new 5-item scale to measure 'Academic Motivation.' To analyze whether this new scale is a valid assessment tool, they decide to conduct a study using correlation. Arrange the following steps of this validation process in the correct logical order.

A research team has developed a new, brief 'Academic Resilience Scale' (ARS) and needs to construct a study design to provide evidence of its validity. Which of the following research protocols should they assemble to best use the correlational method for this validation goal?

A researcher developing a new questionnaire for 'academic motivation' administers it alongside a well-established motivation scale to a group of students. If the new questionnaire is valid, the researcher should expect to find a strong _________ correlation between the scores of the two tests.

A researcher conducts a study to validate a new 'Academic Stress' scale by correlating its results with a well-established stress inventory, finding a correlation of $r = .82$. In their analysis, the researcher identifies the established inventory as the 'independent variable.' When evaluating this methodological approach, a student should conclude that this label is incorrect because correlational research used for validation does not establish _____.

Dr. Green is evaluating the validity of a new 8-item questionnaire designed to measure 'test anxiety' by administering it to 150 students alongside a well-established 40-item test anxiety inventory. If the new questionnaire is a valid measure of test anxiety, Dr. Green should expect a correlation coefficient close to $r = .00$ when analyzing the scores from the two assessments.

A researcher is developing a new 'Empathy Scale' and collects pilot data to evaluate its psychometric properties. They obtain the following correlational results:

• Correlation between the Empathy Scale at Time 1 and Time 2: $r = .88$
• Correlation between the Empathy Scale and a well-established Empathy Inventory: $r = .21$
• Correlation between the Empathy Scale and a Social Desirability Scale: $r = .74$

To diagnose the psychometric quality of this new instrument, arrange the analytical
