01 - Scoring & cutoffs
How scoring works.
Four items, each contributing points as shown against the response options; totals run from 3 to 18. A total of 7 or above is the validated cutoff for adults in the general population (sensitivity 93%, specificity 95%; Osman et al., 2001), and 8 or above is the validated cutoff for adult psychiatric inpatients (sensitivity 80%, specificity 91%). Scores at or above the relevant cutoff warrant a fuller clinical risk assessment.
The SBQ-R is a screening aid, not a risk-prediction instrument or a substitute for clinical assessment. Any endorsement of recent ideation, a plan, or a past attempt merits direct clinical follow-up regardless of the total score.
