Self-Perceived Communication Competence Scale (SPCC)

People's abilities to communicate effectively vary a lot, and sometimes the same person is more competent to communicate in one situation than in another. Please indicate how competent you believe you are to communicate in each of the situations described below. Indicate in the space provided at the left of each item your estimate of your competence. 

Presume 0 = completely incompetent and 100 = competent.

_____1. Present a talk to a group of strangers.
_____2. Talk with an acquaintance.
_____3. Talk in a large meeting of friends.
_____4. Talk in a small group of strangers.
_____5. Talk with a friend.
_____6. Talk in a large meeting of acquaintances.
_____7. Talk with a stranger.
_____8. Present a talk to a group of friends.
_____9. Talk in a small group of acquaintances.
_____10. Talk in a large meeting of strangers.
_____11. Talk in a small group of friends.
_____12. Present a talk to a group of acquaintances.

Scoring: To compute the subscores, add the percentages for the items indicated and divide the total by the number indicated below.

Public 1 + 8 + 12; divide by 3.
Meeting 3 + 6 + 10; divide by 3.
Group 4 + 9 + 11; divide by 3.
Dyad 2 + 5 + 7; divide by 3.

Stranger 1 + 4 + 7 + 10; divide by 4.
Acquaintance 2 + 6 + 9 + 12; divide by 4.
Friend 3 + 5 + 8 + 11; divide by 4.

To compute the total SPCC score, add the subscores for Stranger, Acquaintance, and Friend. Then, divide that total by 3.
Higher SPCC scores indicate higher self-perceived communication competence with basic communication contexts (public, meeting, group, dyad) and receivers (strangers, acquaintance, friend).
