Primary use / Purpose:
The Situational Communication Apprehension Measure (SCAM) was developed to provide and instrument which could measure state CA in any context. This is a self-report instrument which can apply to how a person felt in any recent communication event (the closer in time between the event and completion of this instrument, the more valid the measure will be).
In the example provided, in the directions we describe the communication context as "the last time you interacted with someone who had a supervisory role over you." This may be replaced by any other context, e.g. "talked with one of your subordinates," "talked with your teacher outside class," "met with your physician."
