Management of Differences Inventory

Abstract

The Management of Differences Inventory (MODI) is a 36-item psychological scale developed by H. S. Kindler in 1981. It is designed to assess and analyze an individual’s preferred style for managing differences, disagreements, and workplace conflict management. By asking respondents to divide points between paired statements describing reactions to work-related disagreements, the MODI maps individual behavior onto two critical dimensions: Viewpoint flexibility and Interaction intensity. These dimensions collectively define nine distinct approaches or strategies utilized in organizational settings for resolving differences. The inventory provides a detailed profile of the respondent’s conflict resolution style.

Purpose

The primary purpose of the Management of Differences Inventory (MODI) is to provide employees, particularly managers, with an insightful analysis of their typical style when confronted with disagreements on work-related issues. The scale helps individuals understand their reactive patterns and strategic choices when their views diverge from those of colleagues or stakeholders.

By quantifying responses across 36 paired items, the MODI aims to illuminate the underlying mechanisms that drive an individual’s approach to managing differences. This self-assessment is intended to enhance self-awareness, improve interpersonal effectiveness, and facilitate the development of more constructive organizational behavior and conflict resolution skills.

Construct

The MODI measures the construct of Conflict Management Style as defined by two orthogonal dimensions: Viewpoint flexibility and Interaction intensity. These dimensions form the basis for classifying nine specific approaches to conflict resolution.

  • Viewpoint Flexibility: This dimension reflects how open an individual is to changing or adjusting their initial position. It captures the perceived importance and attainability of the person’s own position, alongside their willingness to learn and incorporate other points of view into the resolution process. A high score suggests an openness to adaptation and learning.
  • Interaction Intensity: This dimension measures the degree of personal involvement and the desired type of relationship outcome during the conflict resolution process. It reflects how actively and assertively the individual engages in the interaction and whether the desired outcome is collaborative, dominant, or accommodative.

These two dimensions define nine specific approaches for managing differences. For each approach, the inventory provides explanations concerning intents, processes, practical applications, and examples. The nine approaches identified are:

  • maintain
  • smooth
  • dominate
  • decide by rule
  • coexist
  • bargain
  • yield
  • release
  • collaborate

Validity

While specific statistical validity coefficients (e.g., criterion or predictive validity) are not detailed in the available abstract, the scale’s construct validity is grounded in the empirical derivation of its core dimensions. The structure of the MODI emerged from the systematic analysis of how managers report preparing to deal with work-related disagreements.

The two resulting dimensions, Viewpoint flexibility and Interaction intensity, provide a theoretically robust framework consistent with established models of conflict management styles, such as those focusing on assertiveness versus cooperativeness. The subsequent definition of nine distinct behavioral approaches further supports the scale’s ability to differentiate between various conflict handling strategies in a work context.

Reliability

Specific data regarding the internal consistency (e.g., Cronbach’s alpha) or test-retest reliability of the Management of Differences Inventory were not provided in the source entry. Reliable application of the instrument depends on the clarity of the items and the consistent interpretation of the frequency scoring system by respondents.

Factor Analysis

The development of the MODI utilized the responses of the initial sample group to identify the foundational structure of conflict management behavior. Based on the responses of over 200 managers detailing their preparation for dealing with divergent views on work-related issues, an exploratory analysis revealed the emergence of two primary factors: Viewpoint flexibility and Interaction intensity. These two factors serve as the organizing dimensions for the entire inventory and its nine behavioral approaches.

Instrument

Test Type: Self-report behavioral inventory; Forced-choice/Paired comparison assessment

Format: 36 items, each consisting of two alternative statements (A and B). Respondents divide 3 points between the two alternatives based on frequency of use.

Language Available: English (Original Publication)

Population Group: Employees, specifically managers and professionals dealing with organizational differences.

Age Group: Adult (Working professionals)

Population Details: Initial sample based on over 200 managers.

Test Methodology: The scale uses a distribution scoring method where respondents allocate three points between two options (A and B) to indicate the relative frequency of each behavior. Scoring options are: Very often = 3; Moderately often = 2; Occasionally = 1; and Rarely or Never = 0. The total score for A plus B must equal 3 for each item pair. The output includes a profile indicating the management style, scoring for the two dimensions (Viewpoint flexibility and Interaction intensity), and an explanation for each of the nine approaches.
