Revised guidelines for Urist's Mutuality of Autonomy Scale (MOA).

Area of Science:

• Psychological assessment
• Personality research
• Psychometrics

Background:

• The Rorschach Mutuality of Autonomy (MOA) scale is a tool for assessing interpersonal relations.
• Previous studies using the MOA scale reported interrater agreement below 80%, raising concerns about data reliability.
• Ambiguous scoring guidelines in existing literature necessitate clarification for accurate application.

Purpose of the Study:

• To revise and clarify the scoring guidelines for the Rorschach Mutuality of Autonomy (MOA) scale.
• To improve interrater agreement to at least 80% for enhanced reliability in future research.
• To provide a clear and unambiguous scoring manual for the MOA scale.

Main Methods:

• A group of 19 naive graduate students initially used existing literature guidelines.
• Raters' agreement was assessed, and guidelines were revised based on performance and feedback.
• A second revision involved the original 19 raters plus 13 new raters to validate improved agreement.

Main Results:

• Initial interrater agreement with existing guidelines was 67%.
• The first revision of guidelines increased agreement to 75% among 19 raters.
• The second revision achieved 80% interrater agreement with a larger group of 32 raters.

Conclusions:

• Revised MOA scale guidelines significantly enhance interrater reliability.
• The improved guidelines address ambiguity and confusion in previous scoring manuals.
• The finalized revised guidelines are suitable for use in new Rorschach studies, ensuring more dependable results.
