Decision Scenario, Treatments, and Manipulation Check Questions

Decision Scenario and Treatments “For the past 3 months you have been working for a U.S.-based call center. This call center employs about 500 qualified customer service representatives who spend most of their time taking incoming calls. Customer service representatives are physically located in one of many working groups. Employees in each working group work in close proximity to each other and have similar job tasks and duties. Working groups consist of 15 employees on average. You have [no // 2] coworkers that you consider to be friends within your working group (though you do have a few coworker friends outside of your working group). Your manager just announced that [a new hire // an acquaintance that you referred // a close friend that you referred] will be joining the company [and will be in your working group // but will not be in your working group].”

Manipulation Check Questions (embedded later in the survey) Which of the following describes the hire in the scenario you read earlier?  The person was a close friend that I referred.  The person was an acquaintance that I referred.  The person was a new hire only (i.e., you did not know this person previously). Where was the hire going to be working at based on the scenario you read earlier?  In your working group  In a different working group Prior to the hire, how many coworker friends were in your working group as indicated in the scenario?  No coworkers  2 coworkers
