Analysis

The Interpersonal Check List (ICL) is a questionnaire developed to assess interpersonal behaviors and attitudes. Its analysis is based on a model that includes various categories of interpersonal relationships and interactions. Each question in the ICL evaluates specific aspects of interpersonal behavior, such as friendliness, aggressiveness, acceptance, and rejection. This tool is particularly useful in psychological and clinical research, as it helps to understand how people interact with others and how these interactions affect their relationships and mental health.

Purpose

The purpose of this questionnaire is to evaluate and understand interpersonal behaviors and relationships. Specifically, the ICL is designed to capture how individuals perceive and interact with others, examining aspects such as friendliness, aggressiveness, acceptance, and rejection. Through its questions, the questionnaire provides a detailed picture of behavioral patterns and emotional responses that characterize interpersonal interactions.
The information collected from the ICL is used to improve the understanding of human behavior, to develop more effective psychotherapeutic interventions, and to enhance the quality of interpersonal relationships. Overall, the main goal of the questionnaire is the promotion of mental health and communication through a thorough assessment of interpersonal dynamics.
