3 68 CHAPTER 3 with children item was restricted to apply only to men with a history of sexual offenses with at least one victim less than 14 years old. The STABLE-2007 has 13 items organized into five subsections (significant social influences, intimacy deficits, sexual self-regulation, general self-regulation, and cooperation with supervision). The items of the STABLE-2007 are presented in Table 3.1 and were scored using 3-point scales (0 = no problem, 1 = some concern/slight problem, 2 = present or definite concern). A score of 2 on any item suggests sufficient concern to be worthy of consideration in treatment, supervision, and management plans of men with a history of sexual offenses. The information required to score the STABLE-2007 was obtained during a structured interview conducted by an officer. When available, evaluators were encouraged to use collateral information, such as police reports, previous presentencing reports, specialized testing, psychological testing, and information from family members, friends, and employers. Data were collected by a total of 156 parole and probation officers who attended a 2-day training session primarily involving descriptions of the scoring criteria combined with exercises. Most of the training sessions were conducted by the principal investigators of the DSP (Karl Hanson and Andrew Harris), although other trainers were used in some jurisdictions. Descriptive and demographic data on the supervision officers were not collected, but the officers would have included men and women with varying levels of expertise and sex crime specialization (Hanson et al., 2007). As part of the DSP project, the interrater reliability of the STABLE-2000 was calculated on the basis of file reviews of 87 randomly selected cases (Hanson et al., 2007). The intraclass correlation coefficient (ICC) for the total score was .89 (for the individual items, range = .66–.92; Mdn = .83). Reliability calculated using this approach would tend to overestimate the interrater agreement; the second raters used case files prepared by the officer who originally scored the case. Second, the ICC of the total score of the STABLE-2000 was calculated on the basis of a structured interview with the offender and the use of collateral information for an initial score at the start of the supervision and a follow-up score after the first 6 months of the supervision period. The ICC for the initial score was .94 (n = 87), and that for the follow-up score was .93 (n = 45). The predictive properties of the STABLE-2007, as measured with the area under the curve, were .67 (95% confidence interval [CI] = [.60, .74]) for sexual recidivism and .67 (95% CI = [.62, .72]) for violent (including sexual contact) recidivism (Hanson et al., 2007). Table 3.1. STABLE-2007 Dynamic risk factors (van den Berg et al., 2020, p. 543) Item Dynamic risk factor Description 1 Significant social influences This item is based on the subtraction of the number of people likely to influence decisions and behavior of the man with a history of sexual offenses in positive versus negative ways. Differences: >2 = score 0, 0 or 1 = score 1, <0 = score 2.
