“…Borowsky, Hogan, and Ireland (1997) found community connectedness and emotional health were the most significant strengths to protect male adolescents against perpetrating sexual violence, while achievement in academia was the key strengths factor for adolescent females. A study involving learning-disabled adolescents who had sexually harmed found that assessment of strengths significantly predicted future desistance from committing both sexual and nonsexual offences (Griffin & Vettor, 2011). Furthermore, research conducted on adolescent males of mainstream ability found that strengths had a real and important role in reducing risks, in that those 'high risk' males who were identified as possessing a number of strengths did not go on to sexually re-offend (Griffin, Beech, Print, Bradshaw, & Quayle, 2008).…”

The Good Lives Model (GLM) is a strengths-based approach that conceptualises sexually harmful behaviour as an individual's inappropriate means to meet their core personal and social needs. It promotes managing potential risk through acknowledging the individual's needs, goals and aspirations and working towards meeting these in safe and positive ways. As a specialist organisation working with adolescents who sexually harm, G-map has adapted the GLM for its client group and employs it as a framework for problem formulation and intervention planning. Using a single case-study design, this paper illustrates how the GLM can be used as a framework for therapeutic practice. The case study involves an adolescent male who sexually assaulted an adult female. G-map's experience of the clinical utility and strengths of the Good Lives Model are discussed, alongside an acknowledgement that the dearth of outcome research relating to this model is a limitation.

“…Findings are reflective of early studies of youth with low intellectual functioning reporting some youth had sexually abused strangers (Gilby et al, 1989;Lane, 1997). Griffin and Vettor (2012) found that the "sexually harmful" male adolescents (p. 69) in their sample who met diagnostic criteria for intellectual disability had "more ingrained behaviour; more distortions supportive of entitlement and control-based strategies for coping" (p. 67).…”

“…A United Kingdom tool, Assessment, Intervention and Moving on Project 2 (AIM2) Print et al, 2007, was designed for male youth, ages 12-18 "of mainstream educational ability who are known to have sexually abused others" (Griffin, Beech, Print, Bradshaw, & Quayle, 2008, p. 213), validated on a small sample of 70 adolescent males. Griffin and Vettor (2012) found good predictive validity when applying an adapted version of AIM-2 to a small sample (N = 46) of male adolescents who "sexually harmed" (p. 64) and met diagnostic criteria for intellectual disability. The other tool, MEGA ♪3 (i.e.…”

Presented are the largest studies in the field of risk assessment of sexually abusive youths, of youth with low intellectual functioning of borderline or below average (n = 746 and n = 522). Youth were part of two major validation studies [1979-2017]: MEGA ♪ Combined Samples Studies (N = 3,901 and MEGA ♪ Combined Cross Validation Studies (N = 2,717). Samples were adjudicated and non-adjudicated (males, females, and transgender-female (Trans-MTF) sexually abusive youth, ages 4-19). The measure employed was the ecologically framed MEGA ♪ risk level assessment tool, with statistically weighted cutoff scores (i.e. normative data, calibrated risk levels grounded on given algorithms) according to age and gender. Presented are findings on descriptive characteristics and risk levels of youth in both samples who have low intellectual functioning of borderline or below average. Risk assessment tools for sexually abusive youth need to show sensitivity to developmental issues, gender, and intellectual functioning, with calibrated risk levels according to age and gender.

“…The findings from a pilot study suggest that the risk scale and strength scale predicted sexual recidivism among a group of youth (Griffin et al, 2008). Similarly, another study demonstrated that the AIM2 predicted sexual reoffending among youth with intellectual disabilities who committed sexual offences (Griffin & Vettor, 2012).…”

The reliability and validity of the SAPROF among forensic mental health patients

Assessing and managing level of risk among forensic mental health patients is a primary role of clinical forensic psychologists. Forensic assessments are focused on risk factors and deficits, whereas patient strengths and protective factors are either partially included or overlooked altogether by forensic psychologists. As a result, less is known about protective factors in general and how they may serve to inform risk management practices. The Structured Assessment of Protective Factors for Violence Risk (SAPROF) is the first tool to exclusively rely on protective factors and was investigated for the current study. The psychometric properties of the SAPROF were examined using a sample of 50 Canadian patients found Not Criminally Responsible (NCR) at a psychiatric hospital using both file information and semi-structured interviews. Outcome variables included risk management decisions (change in privilege level and security level) and indicators of recidivism (psychiatric medication administration, institutional misconduct and disposition breaches). The study found some evidence for intrarater and interrater reliability, construct validity, predictive validity and incremental predictive validity. The SAPROF approached significance for adding incremental predictive validity to the HCR-20 V3, a measure of violence risk, for disposition breaches and institutional misconduct, and effect sizes doubled. Given that the addition of the SAPROF increased the accuracy of the violence risk assessment, there are considerable implications for informing clinical practice. Implications for risk assessment, treatment planning, intervention and risk management decisions implemented by review boards and clinical practitioners are discussed. It is recommended that the SAPROF be added as an adjunct measure to risk assessment batteries and included in hospital reports, given that it predicted several patient behaviours.
