The Beck Inventory: psychometric properties in university students

Area of Science:

• Psychology
• Clinical Psychology
• Psychometrics

Background:

• The Beck Depression Inventory (BDI) is a widely used self-report measure for assessing depression.
• A revised, copyrighted version, the Beck Inventory (BI), was developed to potentially refine depression assessment.

Purpose of the Study:

• To evaluate the psychometric properties of the Beck Inventory (BI).
• To compare the BI's performance against the established Beck Depression Inventory (BDI).

Main Methods:

• The study involved 204 university students.
• Psychometric properties including test-retest reliability and concurrent validity were assessed.
• The BDI was used as the criterion for concurrent validity.

Main Results:

• The Beck Inventory (BI) exhibited excellent two-week test-retest reliability (.90) and internal consistency (coefficient alpha = .87).
• Concurrent validity was high, with a correlation of .94 against the BDI.
• A statistically significant, though small, difference in mean scores was observed, with the BI yielding slightly lower scores, particularly on items related to Sadness, Suicidal Ideas, and Insomnia.
• Depression levels showed no significant relationship with demographic variables.

Conclusions:

• The Beck Inventory (BI) is a psychometrically sound instrument for measuring depression.
• The BI shows high reliability and validity, comparable to the BDI.
• The BI may offer a slightly more sensitive measure for specific depressive symptoms.
