This research examines the importance of assessing motivations that cr
isis patients attribute for considering a suicide attempt. For 251 con
secutive patients attending a crisis unit, suicide attempters and idea
tors indicated agreement with each of 14 reasons for attempting suicid
e. Principal components analysis of these agreement ratings yielded tw
o factor scales of motives: Extrapunitive/Manipulative Reasons and Int
ernal Perturbations. Scores for internal perturbations correlated sign
ificantly with patients' wishes to die, clinicians' ratings oi patient
s' suicidal desire and preparation for suicide, and clinicians' overal
l evaluation of patients' suicidal risk. Associations between internal
perturbations and these suicide measures were nonredundant with hopel
essness. It is concluded that evaluating a suicidal person's internal
reasons for attempting suicide has unique assessment value. (C) 1998 J
