Communication · Executive Insight Brief · 192
Ten dimensions are not ten reliable scores
Ten self-reported dimensions organize development while observed interpersonal effectiveness remains separate evidence.
Premise
Interpersonal competence is easily reduced to confidence, fluency, or executive presence. Rubin and Martin’s ICCS widens the construct by integrating ten communication dimensions, allowing leaders to examine perceived capability as a pattern rather than a single impression. Its use remains bounded: the instrument records how people describe their characteristic communication. It does not directly observe conduct, certify competence across relationships, or establish a fixed interpersonal type.
