A sample of 119 female suicide attempters completed the Beck Scale for Suicide Ideation. Although confirmatory common factor analyses failed to support previously hypothesized one-, two-, or three-factor models, confirmatory principal components analyses substantiated hypothesized one- & two-dimensional models. Heuristics for the number of factors converged on two latent dimensions & exploratory principal components analyses verified the presence of 2 previously hypothesized suicide ideation factors – motivation & preparation. Scales based on this two-dimensional model demonstrated convergent validity with other suicide indices. (33 refs.)
