Objectives:Structured professional judgement is now the most widely accepted approach to clinical risk assessment and risk management. The Suicide Risk Assessment and Management Manual (S-RAMM) is a new structured professional judgement tool closely modelled on the HCR-20. This is the first prospective validation study for this instrument.Methods:Two post-membership registrars jointly interviewed 81 of 83 current inpatients to rate the S-RAMM. Two assistant psychologists independently rated the HCR-20, GAF and PANSS. All incidents of self-harm, attempted suicide, suicide and violence to others were collated from hospital reporting of critical incidents over the next six months supplemented by examination of other records.Results:For combined self-harm and suicide outcomes, the S-RAMM total score using the receiver operating characteristic had an area under the curve AUC=0.89, (95% CI 0.79 to 0.99). The S-RAMM performed as well for the prediction of self-harm and suicide as the HCR-20 did for violence, and better than measures of mental state (PANSS total score) and global function (GAF).Conclusions:The S-RAMM has better than minimum acceptable characteristics for use as a clinical or research tool for suicide risk assessment, and performs almost as well as the HCR-20 does for violence. Further prospective studies are now required, in other populations.
Objective:There are validated tools for structured professional judgement of risk of violence, but few for risk of suicide. The Suicide Risk Assessment and Management Manual (S-RAMM) is a new structured professional judgement tool closely modelled on the HCR-20. This is the first validation study for the S-RAMM. We measured inter-rater reliability, internal consistency, concurrent validity with another validated risk instrument (HCR-20) and with a measure of psychopathology (PANSS). We tested whether the tool could distinguish between groups of patients clinically assessed as at varying levels of risk of suicide or self harm.Method:Two researchers jointly interviewed 25 current in-patients for inter-rater reliability (Cohen's kappa) and internal consistency (Cronbach's alpha) and interviewed 81 of 83 current in-patients to assess whether the mean scores for different wards were significantly different (using ANOVA). Two other researchers made independent ratings of the HCR-20 and PANSS.Results:Inter-rater reliability was acceptable for all items (Cohen's kappa >0.5 for all but three items) and all sub-scale and total scores (Spearman correlations all >0.8). Internal consistency was high, (Cronbach's alpha all sub-scales >0.6). Scores stratified significantly with high scores for admission and intensive care units and progressively lower scores in rehabilitation and predischarge units. The HCR-20 historical and S-RAMM background scores did not correlate but the dynamic sub-scales correlated significantly. PANSS scores also correlated significantly with S-RAMM scores.Conclusion:The S-RAMM has better than minimum acceptable characteristics for use as a clinical or research tool. Prospective studies of sensitivity and specificity are now required.
