Instrument Description

The Susceptibility to Infidelity Instrument (SII) is a psychometric tool designed to assess an individual’s likelihood or susceptibility to engaging in infidelity within a relationship. This tool examines various psychological and behavioral factors that may contribute to infidelity, helping researchers and therapists better understand the dynamics leading to this behavior.

Data Analysis and Use

The analysis of responses to the SII involves evaluating answers to a series of statements related to behaviors, attitudes, and perceptions regarding infidelity. Responses are typically scored on a five-point Likert scale (from 1 = Strongly Disagree to 5 = Strongly Agree). The statements may cover various aspects, such as:

  • Personal Morality and Values: Perceptions regarding ethics and commitment in relationships.
  • Relationship Satisfaction: Levels of satisfaction and communication within the relationship.
  • Social Influences: Impact of friends and social circles on the individual’s behavior.
  • Opportunities for Infidelity: Situations and environments that may facilitate infidelity.

Objective

The goal of the SII is to provide a reliable and valid measure of susceptibility to infidelity. This measure can be used to identify individuals who may be at risk of engaging in infidelity and to develop interventions aimed at enhancing relationship stability and commitment.

Calibration

Calibration of the SII involves calculating total scores for each of the categories, as well as an overall susceptibility to infidelity score. These scores can be categorized to indicate levels of susceptibility to infidelity:

  • Low Susceptibility to Infidelity: Indicates that the individual has a low risk of engaging in infidelity.
  • Moderate Susceptibility to Infidelity: Indicates that the individual has a moderate risk of engaging in infidelity.
  • High Susceptibility to Infidelity: Indicates that the individual has a high risk of engaging in infidelity.
