In order to assess the reliability and validity of Cole's (1988) four-
item version of the Suicidal Behaviors Questionnaire (SBQ), 57 clinica
l outpatients completed it and the Reasons for Living Inventory (RFL),
and 86 undergraduates completed it and the Scale for Suicide Ideation
(SSI). Two weeks later, 30 undergraduates completed the SBQ again. Cr
onbach alphas were moderate (clinical sample = .75; nonclinical sample
= .80). Test-retest correlations were also significant (r = .95). The
SBQ and SSI were significantly correlated (r = .69). The SBQ and RFL
were also significantly correlated (r = -.34), although modestly. In v
iew of its moderate to strong reliability, its construct and fact vali
dity, its ease of administration and scoring, and its brevity, the SBQ
is recommended as a brief screening instrument for suicidality for re
searchers and clinicians.
