Definition

DEPI is a composite index that summarizes how many signs in the protocol point toward depressive features. It integrates variables from affect, burden, negative self-image, and emotional withdrawal.

Interpretation

• If DEPI is positive, assess depressive symptoms more closely without assuming that discouragement, hopelessness, guilt, or loss of energy is present from the index alone.
• The index gains meaning when it appears together with SumV, SumY, MOR_self, and altered Afr.
• Its empirical support is limited, so it sets an assessment priority rather than establishing a probable depressive pattern or episode.
• If CDI is also positive, vulnerability may be mixed with a stronger sense of helplessness.

Cautions

• A positive DEPI is not automatically a formal diagnosis.
• A negative DEPI does not exclude depression.
• Life context, grief, and recent stress can influence the constellation.

Cautions

• The base variables should be reviewed before fixing a clinical conclusion.
• It should be integrated with Affect, SumV, SumY, MOR_self, and CDI.

Evidence Strength

• Evidence tier: limited
• Empirical support for depression-related constructs is limited. A positive result calls for further assessment; it is not evidence of particular symptoms or a diagnosis.
• Separately assess current mood, anhedonia, sleep and appetite, guilt, suicidal ideation, duration, and functional impairment, and do not use a negative result to rule out depression.
