Scale Description

The Self-Perceived Communication Competence Scale (SPCC) is a psychometric tool designed to assess individuals’ self-perception regarding their communication abilities. Developed by James C. McCroskey, it is widely used in research to measure how individuals evaluate their own communication skills across various social and professional contexts.

Data Analysis and Use

The analysis of SPCC responses involves evaluating answers to 12 statements related to communication competence in different social contexts. These statements assess individuals’ self-perception in four different settings:

  • Public Speaking
  • Group Discussion
  • Interpersonal Communication
  • Communication with Strangers

Responses are rated on a five-point Likert scale (from 1 = Very Low Ability to 5 = Very High Ability). Participants are asked to evaluate their abilities in various communication situations, such as speaking in front of an audience, participating in group discussions, communicating with friends, and interacting with strangers.

Objective

The goal of the SPCC is to provide a reliable and valid measure of individuals’ self-perception of their communication competence. This measurement can be used by researchers and professionals to better understand how people perceive their own communication abilities and to develop interventions aimed at improving these skills.

Calibration

Calibration of the SPCC involves calculating the total scores for each of the four categories, as well as an overall self-perception score of communication competence. These scores can be categorized to indicate levels of self-perceived communication competence:

  • Low Self-Perception of Ability: Indicates that the individual perceives their communication skills as inadequate.
  • Moderate Self-Perception of Ability: Indicates that the individual has moderate confidence in their communication skills.
  • High Self-Perception of Ability: Indicates that the individual has high confidence in their communication skills.
