“…The Willingness to Intervene against Suicide questionnaire (WIS; Aldrich et al, 2014) was developed based on the TBP (Ajzen, 1985) and is composed of four subscales measuring attitudes, subjective norms, PBC and intention to intervene. Previous research shows the subscales within the WIS range in reliability from .72 to .90 (Aldrich, 2015; Aldrich et al, 2014). Both the pretest and posttest used the WIS subscales to measure attitudes about suicide intervention (14 items, pretest, α = .83; posttest, α = .75), subjective norms regarding support from important others (9 items, pretest, α = .77; posttest, α = .75), PBC regarding intervention (17 items, pretest, α = .87; posttest, α = .91), intention to intervene with a suicidal individual (20 items, pretest, α = .89; posttest, α = .88) and experience with mental health issues, family history of mental health issues, experience with suicide, experience with intervention and demographic information.…”
