Development and Validation of the Scale for Understanding Life-Oriented Expression and Dispositions.

Area of Science:

• Psychology
• Personality Science

Background:

• Existing temperament and personality measures have limitations in capturing motivational drives and relational context.
• A need exists for a comprehensive tool to assess adult dispositional orientations across multiple life domains.

Purpose of the Study:

• To develop and validate the Scale for Understanding Life-Oriented Expression and Dispositions (SULEDIS), a self-report instrument for assessing adult life orientations.
• To provide a nuanced framework for understanding adult dispositions beyond trait-based models.

Main Methods:

• The SULEDIS was developed through theoretical review, expert consultation, and item refinement, utilizing a dual-axis framework.
• The scale assesses four orientations (health, relationships, achievement, meaning) across three domains (self, family, organization) using 96 forced-choice items.
• Data from 212 adults were analyzed for reliability, validity, and factorial structure using Categorical Principal Component Analysis (CATPCA).

Main Results:

• Most SULEDIS subscales demonstrated adequate internal consistency and test-retest reliability.
• Correlation analyses showed coherent relationships among subscales, with strong correlations between self-meaning (r=-0.78) and organization-meaning (r=0.79).
• The scale exhibited partial convergent validity with traditional personality assessments, and CATPCA confirmed consistent three-factor structures.

Conclusions:

• The SULEDIS offers a practical and nuanced framework for understanding adult dispositions.
• The scale has promising applications in counseling, education, and personal development.
• SULEDIS provides a valuable alternative to trait-based models for dispositional assessment.
