There is an error in the fifth sentence under the “Participants” heading of the Materials and Methods section. The correct sentence is: Participants’ mean age at the time of their first ROM assessment was 40 years (SD = 10.15, range = 22–72). There is an error in the first sentence of the Results section. The correct sentence is: For the whole group of patients, 867 IFTEs were assessed between September 2011 and June 2014. There are errors in the second and third sentences of the first paragraph under the “Leave approval” heading of the Results section. The correct sentences are: For the patients who had not received guided leave approval, the mean protective behaviour scores (t (211) = -2.7, p = .01) and mean resocialization skills scores (t (63.42) = -5.09, p = .00) on the IFTE were significantly lower (MProtective behaviour = 43.60, SD = 15.19, N = 183; MResocialization skills = 49.88, SD = 17.91, N = 202) than those of patients who had received guided leave approval (MProtective behaviour = 51.56, SD = 13.27, N = 30; MResocialization skills = 61.59, SD = 11.06, N = 33). Problem behaviour scores did not differ significantly (t (284) = 1.36, p = .18). There are errors in the second paragraph under the “Leave approval” heading of the Results section. The correct paragraph is: Mean factor scores differed significantly for patients who had and patients who had not received unguided leave approval on protective behaviour (t (428) = -3.13, p = .00), problem behaviour (t (45.11) = 4.07, p = .00) and resocialization skills (t (40.02) = -5.50, p = .00). Mean factor scores for patients who had not received unguided leave approval was MProtective behaviour = 48.41 (SD = 15.15, N = 407), MProblem behaviour = 41.83 (SD = 16.32, N = 535) and MResocialization skills = 54.05 (SD = 17.41, N = 439). Mean factor scores for the patient group who had received unguided leave approval were MProtective behaviour = 58.47 (SD = 11.87, N = 23), Mproblem behaviour = 33.95 (SD = 10.68, N = 35) and MResocialization skills = 65.32 (SD = 10.08, N = 29). There are errors in the third paragraph under the “Leave approval” heading of the Results section. The correct paragraph is: The patient group who had not received transmural leave approval also differed significantly from patients who had received transmural leave approval, on protective behaviour (t (496) = -2.20, p = .03) and problem behaviour, t (39.06) = 3.91, p = .00). Mean factor scores for patients who had not received transmural leave approval were MProtective behaviour = 49.99 (SD = 15.01, N = 474) and MProblem behaviour = 40.87 (SD = 15.86, N = 641). Mean factor scores for the patient group who had received transmural leave approval were MProtective behaviour = 56.90 (SD = 14.70, N = 24) and MProblem behaviour = 32.27 (SD = 12.30, N = 34). There are errors in the second sentence of the first paragraph under the “General and physical aggression Main group” heading of the Results section. The correct sentence is: Forty incidents of physical aggression were reported approximately 10.52 weeks after assessment (SD = 11.01, range = 0–54). There are errors in the fourth and fifth sentence of the first paragraph under the “General and physical aggression Main group” heading of the Results section. The correct sentences are: One-hundred and fifty-eight general aggressive incidents were reported approximately 10.51 weeks after assessment (SD = 9.87, range = 0–54). Two-hundred and twenty-six UDS violations were reported approximately 8.96 weeks after assessment (SD = 10.32, range = 0–58). There are errors in the second and third sentences of the first paragraph under the “Personality-disordered group” heading of the Results section. The correct sentences are: Twenty-nine physical aggression incidents were reported approximately 10.97 weeks after assessment (SD = 11.39, range = 0–54). One-hundred and three general aggression incidents were reported approximately 9.95 weeks after assessments (SD = 9.87, range = 0–54), and 164 UDS violations were reported approximately 9.76 weeks after assessments (SD = 10.93, range = 0–58). There are errors in the second and third sentences of the first paragraph under the “Personality disordered group with co-morbid substance use disorders” heading of the Results section. The correct sentences are: For the PSDS group, including 91 patients, 22 physical aggression incidents were reported approximately 8.32 weeks after assessment (SD = 7.57, range = 0–26), and 70 general aggression incidents approximately 8.26 weeks after assessment (SD = 8.95, range = 0–37). One hundred and thirty-six UDS violations were reported approximately 9.88 weeks after assessment (SD = 10.12, range = 0–58). There are errors in the seventh and eight sentences of the Discussion section. The correct sentences are: All resocialization items, apart from self-care skills, showed a significant predictive validity for unguided leave. Treatment cooperation, working skills, rule compliance and skills to prevent substance use were most predictive of unguided leave. There are errors in the tenth sentence of the Discussion section. The correct sentence is: Antisocial behaviour, hostility, manipulative behaviour, and rule compliance were all marginally predictive of transmural leave. There are errors in Tables 3–6.
