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