Description

The Interpersonal Communication Inventory (ICI-80) is a psychometric instrument designed to assess an individual’s interpersonal communication skills, attitudes, and communication effectiveness. The questionnaire evaluates the ability to communicate clearly, listen actively, express emotions appropriately, understand others’ perspectives, and adapt communication styles across different social and professional situations.

The ICI-80 consists of 80 items that examine multiple dimensions of interpersonal communication, including active listening, verbal and non-verbal communication, emotional expression, empathy, feedback, assertiveness, conflict management, and responsiveness to different communication styles. The instrument provides a comprehensive assessment of communication competence, helping identify both strengths and areas requiring further development.

The scale is widely used in organizational psychology, counseling psychology, educational psychology, communication research, human resource management, and leadership development, where effective interpersonal communication is recognized as a fundamental component of individual and organizational success.

Analysis and Use of Data

The analysis of the ICI-80 is based on participants’ responses to 80 items, typically rated using a Likert-type response scale.

The instrument evaluates multiple dimensions of interpersonal communication by calculating both overall and subscale scores, allowing researchers and practitioners to identify areas in which individuals demonstrate effective communication skills as well as areas requiring improvement.

The collected data can be used to investigate relationships between interpersonal communication and variables such as emotional intelligence, empathy, leadership, teamwork, organizational commitment, job satisfaction, conflict management, psychological well-being, academic achievement, and social competence. Comparative analyses may also be conducted across demographic groups, occupational sectors, educational settings, or organizational levels.

Psychometric evaluation of the ICI-80 generally includes the assessment of internal consistency using Cronbach’s alpha, test–retest reliability, and construct validity through exploratory or confirmatory factor analysis. Researchers may also examine convergent and discriminant validity by comparing ICI-80 scores with other measures of communication competence, emotional intelligence, social skills, and interpersonal functioning.

Objective

The primary objective of the Interpersonal Communication Inventory (ICI-80) is to provide a reliable and valid assessment of interpersonal communication effectiveness. More specifically, the instrument aims to:

  • Assess individuals’ interpersonal communication skills.
  • Evaluate strengths and weaknesses across different communication dimensions.
  • Enhance communication self-awareness.
  • Support research examining communication competence in personal, educational, and occupational settings.
  • Facilitate the development and evaluation of communication training and professional development programs.

Scoring

The ICI-80 consists of 80 items, which are scored according to the administration guidelines of the instrument using a Likert-type response scale.

Overall scores and subscale scores are calculated by summing or averaging participants’ responses. Higher scores indicate more effective interpersonal communication, stronger listening skills, greater empathy, clearer emotional expression, and better adaptability across different communication contexts. Lower scores suggest reduced communication effectiveness and identify areas that may benefit from communication skills training or professional development.

For research purposes, it is recommended that the psychometric properties of the instrument be evaluated using Cronbach’s alpha, test–retest reliability, and construct validity analyses.

Applications

The Interpersonal Communication Inventory is widely used in organizational psychology, educational psychology, counseling psychology, communication studies, leadership research, human resource management, and organizational behavior. It has been applied in studies investigating communication competence, leadership effectiveness, teamwork, emotional intelligence, conflict resolution, counseling effectiveness, employee performance, academic achievement, and interpersonal relationships.

In professional practice, the ICI-80 assists psychologists, counselors, educators, trainers, managers, and human resource professionals in evaluating communication competence, identifying developmental needs, designing communication training programs, and monitoring improvements following educational or organizational interventions.
