SIBAT was specifically developed to measure rapid change in suicidality, based on concerns that existing scales such as BSS are not designed to discriminate differences associated with rapid change. Patient-rated section includes following modules: Module 1 (M-1)(demographic information,suicide history), M-2(current suicidal thinking),M-3 (protective factors), M-4 (suicide behavior),M-5(suicide risk),M-6(suicide-implicit association test).Patient-reported global assessment of suicide risk summarizes patient's judgment of suicide risk (Module 6). Scores: 0(None), 1(Very weak), 2(Weak), 3(Moderately weak), 4(Mild), 5(Moderate), 6 (Moderately strong), 7(Strong), 8(Extremely strong), 9(Extremely strong,constant). Negative change in score indicates improvement. LOCF approach used for missing visit data in ITT LOCF efficacy analyses, last post baseline observation was carried forward as the "End Point" follow up phase.
