Abstract
The Computer-mediated communication (CMC) Competence Scale, primarily developed by Spitzberg (2006), is a comprehensive psychometric instrument designed to assess an individual’s perceived ability and disposition toward effective communication in digital environments. This scale operationalizes communication competence across multiple dimensions, including internal factors like Motivation and Knowledge, behavioral factors categorized under Skills (e.g., Coordination, Expressiveness, Composure), and perceptual outcomes (e.g., Effectiveness, Satisfaction, Appropriateness). The instrument moves beyond simple technology usage to measure the sophisticated psychosocial processes involved in successful digital interaction, recognizing that competence in computer-mediated environments is a complex, multi-faceted construct.

Purpose
The primary purpose of the CMC Competence Scale is to provide a robust, multi-dimensional measure for researchers and practitioners to evaluate individual differences in adapting and performing effectively within various computer-mediated communication contexts. It seeks to quantify how well individuals manage the unique challenges and opportunities presented by digital media, such as asynchronous delays, lack of nonverbal cues, and rapid technological change.
The scale aids in identifying specific areas—ranging from technical confidence (Efficacy) to strategic choices (Selectivity) and interactional quality (Attentiveness, Appropriateness)—where an individual excels or struggles in CMC. This detailed assessment allows for targeted interventions or training programs aimed at enhancing overall digital communication proficiency.
Construct
The scale measures CMC Competence, which is theoretically grounded in the traditional model of communication competence, conceptualized as an interaction of Motivation, Knowledge, and Skills (Morreale, Spitzberg, & Barge, 2001). However, this instrument adapts the model specifically to the digital domain, integrating 15 distinct factors grouped into three main categories:
- Motivation/Arousal: Factors related to the desire, enjoyment, and anxiety surrounding CMC usage (Motivation, Composure, Attractiveness).
- Knowledge/Cognition: Factors concerning understanding how to communicate effectively through digital media and confidence in using new technologies (Knowledge, Efficacy).
- Skills/Behavior: Specific interactional abilities and strategic choices made during CMC (Coordination, Attentiveness, Expressiveness, Selectivity, Appropriateness, Effectiveness, Clarity, Satisfaction, Efficiency/Productivity, General Usage).
Validity
The scale’s validity is supported by its careful development process, which aimed to establish strong construct validity by linking items directly to established theoretical dimensions of competence. Spitzberg (2006) detailed the preliminary development and testing, indicating that the multi-dimensional structure successfully mapped onto the proposed components of CMC competence.
Furthermore, the inclusion of outcome-oriented dimensions (Effectiveness, Satisfaction) and strategic dimensions (Selectivity) demonstrates the instrument’s ability to predict and reflect successful communication outcomes, lending support to its predictive validity within the context of digital interaction studies.
Reliability
The internal consistency of the subscales, assessed using Cronbach’s alpha, demonstrates generally high reliability across the major dimensions, though some usage-oriented subscales show lower scores. The reliability coefficients reported by Bubaš et al. (2003) and confirmed in subsequent research (Spitzberg, 2006) are as follows:
- High Reliability (Alpha > .80): Knowledge (.90), Motivation (.85), Efficacy (.85), Composure (.88), Appropriateness (.87), Effectiveness (.85), CMC Interactivity Orientate (.87).
- Moderate Reliability (Alpha .70 – .79): Coordination (.78), Attentiveness (.82), Expressiveness (.74), Satisfaction (.78), Task Orientation (.77), Co-orientation (.80), Productivity/Efficiency (.72).
- Acceptable Reliability (Alpha < .70): General Usage (.65).
These values suggest that the core cognitive and affective components of the scale are highly reliable measures of their respective constructs.
Factor Analysis
While the specific details of the initial factor analysis method (e.g., Exploratory Factor Analysis or Confirmatory Factor Analysis) are elaborated upon in the seminal 2006 article, the resulting structure confirms a highly differentiated, multi-factor model. The scale is organized into 15 distinct factors, which are clustered under the broader headings of Motivation, Knowledge, Efficacy, and various Skill categories (Coordination, Attentiveness, Expressiveness, Composure, Selectivity, Appropriateness, Effectiveness, Clarity, Satisfaction, Attractiveness, Efficiency/Productivity, General Usage).
This extensive factor structure allows researchers to analyze specific facets of competence rather than relying solely on a single, global CMC competence score. The factors concerning Efficacy and Motivation often emerge as key drivers influencing performance across the various behavioral skill dimensions.
