This research examines the importance of assessing motivations that crisis patients attribute for considering a suicide attempt. For 251 consecutive patients attending a crisis unit, suicide attempters and ideators indicated agreement with each of 14 reasons for attempting suicide. Principal components analysis of these agreement ratings yielded two factor scales of motives: Extrapunitive/Manipulative Reasons and Internal Perturbations. Scores for internal perturbations correlated significantly with patients' wishes to die, clinicians' ratings of patients' suicidal desire and preparation for suicide, and clinicians' overall evaluation of patients' suicidal risk. Associations between internal perturbations and these suicide measures were nonredundant with hopelessness. It is concluded that evaluating a suicidal person's internal reasons for attempting suicide has unique assessment value. (C) 1998 John Wiley & Sons. Inc.
