Background

Measurement is important for many areas of organizational psychology, but is especially relevant when considering employee selection and performance evaluation. Suppose you are hiring a new Ultrasound Technician for your hospital. According to your most recent job analysis, Ultrasound Technicians:

• review the patient's medical history and physician's instructions and prepare equipment for the procedure according to specifications of examination.
• greet the patient and explain procedures, record any medical history that may be relevant, and assist the patient in assuming physical positions for examination.
• operate Ultrasound equipment as required, to obtain diagnostic exams according to specifications.
• care for and treat patients of all age ranges who may use perinatal services.
• complete other similar and related duties as assigned.

The performance criteria for this position that the individual will be evaluated on bi-annually include the following:

1. Accuracy of medical reports obtained for diagnostic tests
2. Patient care and satisfaction
3. Attitude

Using this information, please complete Parts A, B, and C.

Part A: The Outcomes

Operationally define and determine how you would measure each of the performance constructs. There are many possible answers, so be creative and specific. There are no wrong answers as long as you justify your response. Hint: a criterion is the outcome variable (like your dependent variable).

Criteria	Operational Definition	Suggested measurement for performance evaluation based on operational definition
1. Accuracy of medical reports
2. Patient care and satisfaction
3. Attitude

Part B: The Predictors

Given everything you know about this position and the performance criteria expected; identify two constructs you would measure during the selection process to choose the best candidate. In other words, what three (or more) predictor variables are needed at the time of hire, how would you define these constructs, and how would you measure them? Hint: A predictor is like your independent variable.

Part C: How Did We Do?

Let's suppose that you have been using these two selection methods for about five years. Your boss wants you to determine whether your selection tools are reliable and valid. Given everything you've read in Chapter 3, explain how you would determine the test-retest reliability and construct and predictive validities of your measures?Be specific.
