HCR-20V3 = Historical, Clinical, Risk Management-20, Version 3. Maximum/minimum values = 0–20 (H), 0–10 (C & R). SAM = guidelines for Stalking Assessment and Management. Maximum/minimum values = 0–20 (Nature of stalking), 0–20 (Perpetrator risk factors). SRP = Stalking Risk Profile. SRR = Summary risk rating. ICCA,1 = intraclass correlation coefficient, single measure (absolute agreement). Kw = weighted kappa.
Bolded items: p ≤ .001.
↵a Difference scores calculated as the difference between the last follow-up and baseline risk scores.
↵b Scale reliability calculated on those items common across motivational types (n = 12 for Stalking violence; n = 4 for Recurrence). The Persistence (12 items) and Psychosocial damage (11 items) scales contain the same items across each typology.
