A factorial analysis of BDI scores

Undertook a factorial analysis of the BDI on a sample of 214 male cardiac outpatients. The factor structure yielded three psychologically distinct dimensions interpreted as negative self‐attitudes, physiological symptoms and sadness. The sample was divided into depressed and nondepressed subgroups in order to investigate whether the BDI factor structure is dependent on the range of BDI scores selected. While the first two factors from the nondepressed group's scores mimicked those for the full sample, in general the subgroups' factor structures provided no clear interpretation.
