Multiple linear regression model of factors associated with higher vulnerability index (VI) scores.

VI score was associated more strongly with unipolar than bipolar (I or II) depression and with lower self-ratings of suicidal ideation or wish to die, but was not associated with self-reported depressed mood. Factors not associated with VI score included sex, age, clinician-rated dysphoria, and self-ratings of dysphoria, vital drive, anxiety, unusual bodily experiences, autonomic symptoms, or total morbidity.
