Communicative Competence Scale
Wiemann (1977) created the Communicative Competence Scale (CCS) to measure communicative competence, an ability "to choose among available communicative behaviors" to accomplish one's own "interpersonal goals during an encounter while maintaining the face and line" of "fellow interactants within the constraints of the situation" (p. 198). Originally, 57 Likert-type items were created to assess five dimensions of interpersonal competence (General Competence, Empathy Affiliation/Support, Behavioral Flexibility, and Social Relaxation) and a dependent measure- (interaction Management). Some 239 college students used the scale to rate videotaped confederates enacting one of four role-play interaction management conditions (high, medium, low, rude). The 36 items that discriminated the best between conditions were used in the final instrument. Factor analysis resulted in two main factors-general and relaxation-indicating that the subjects did not differentiate among the dimensions as the model originally predicted.
Subjects use the CCS to assess another person's communicative competence by responding to 36 items using Likert scales that range from strongly agree (5) to strongly disagree (1). The scale takes less than 5 minutes to complete. Some researchers have adapted the other-report format to self-report and partner-report. These formats are available from the author.
The CCS appears to be internally consistent. Wiemann (1977) reported a .96 coefficient alpha (and .74 magnitude of experimental effect) for the 36item revised instrument. McLaughlin and Cody (1982) used a 30-item version for college students to rate their partners after 30 minutes of conversation and reported an alpha of .91. Jones and Brunner (1984) had college students rate audio-taped interactions and reported an overall alpha of .94 to .95; subscale scores had alphas ranging from .68 to .82. Street, Mulac, and Wiemann (1988) had college students...
