How to integrate the good lives model into treatment programs for sexual offending : an introduction and overview

Gwenda M. Willis; Pamela M. Yates; Theresa A. Gannon; Tony Ward

The good lives model (GLM) represents a new theoretical framework informing sex offender treatment programs; however, substantial variation has been observed in terms of how GLM-related ideas and practices have been applied. Integrated appropriately, the GLM offers potential for improving outcomes of programs following a cognitive-behavioral therapy (CBT) approach and operating according to a narrow operationalization of risk, need, responsivity (RNR) principles. Conversely, misguided or otherwise poor integration could increase the very risk practitioners work to prevent and manage. The purpose of this article is to provide an introduction and overview on how to integrate the GLM into treatment using CBT and RNR. The authors describe clinical implications of the GLM as they relate to program aims and orientation, assessment and intervention planning, content, and delivery.

The Good Lives Model in Practice: Offence Pathways and Case Management

Mayumi Purvis; Tony Ward; Gwenda M. Willis

During the past decade, the Good Lives Model of Offender Rehabilitation (GLM) has gained considerable momentum and popularity as a rehabilitation framework for forensic populations. The GLM is primarily applied by the treatment sector, however very recently, it has been used to generate a structured strengths based approach to case management. The purpose of this paper is multi-layered. First, we present the theory of the GLM, explaining its conceptual underpinnings and in addition, present the results of recent GLM empirical research that found two pathways to offending: direct and indirect. Next, we describe how the GLM conceptual underpinnings, together with the empirical research findings, translate into a structured and meaningful case management approach for community corrections. The process for effective case management of offenders using the GLM is outlined and further, two GLM case management tools are presented and their purpose and application to offender rehabilitation is briefly set out. Finally, we describe the necessary support factors that are vital to the integrity, success and sustainability of this case management approach.

Adverse Childhood Experiences in the Lives of Male Sex Offenders: Implications for Trauma-Informed Care

Jill S. Levenson; Gwenda M. Willis; David S. Prescott

This study explored the prevalence of childhood trauma in a sample of male sexual offenders (N = 679) using the Adverse Childhood Experience (ACE) scale. Compared with males in the general population, sex offenders had more than 3 times the odds of child sexual abuse (CSA), nearly twice the odds of physical abuse, 13 times the odds of verbal abuse, and more than 4 times the odds of emotional neglect and coming from a broken home. Less than 16% endorsed zero ACEs and nearly half endorsed four or more. Multiple maltreatments often co-occurred with other types of household dysfunction, suggesting that many sex offenders were raised within a disordered social environment. Higher ACE scores were associated with higher risk scores. By enhancing our understanding of the frequency and correlates of early adverse experiences, we can better devise trauma-informed interventions that respond to the clinical needs of sex offender clients.

The Good Lives Model (GLM) An Evaluation of GLM Operationalization in North American Treatment Programs

Gwenda M. Willis; Tony Ward; Jill S. Levenson

The good lives model (GLM) has become an increasingly popular theoretical framework underpinning sex offender treatment programs, and preliminary research suggests that the GLM may enhance the efficacy of programs that adhere to the Risk, Need, and Responsivity (RNR) principles. However, this potential rests on the appropriate operationalization of the GLM in practice. Operationalized appropriately, the GLM aims to facilitate risk reduction alongside equipping clients with the tools to live personally meaningful and fulfilling lives. However, misguided operationalization of the GLM could result in ineffective treatment and ultimately higher rates of reoffending. This article presents findings from a multisite study exploring how the GLM has been operationalized and the degree to which the GLM has been integrated in a sample of 13 North American treatment programs. A comprehensive coding protocol was developed that included items related to program aims and client induction/orientation, assessment, intervention planning, intervention content, and intervention delivery. Each site was visited and items were rated through a review of program documentation, interviews with program directors/managers, and observations of treatment groups. Findings from inductive (how the GLM was operationalized) and deductive (the extent to which the GLM was integrated) analyses are presented and GLM consistent and inconsistent practices are highlighted. The article concludes with suggestions for ways in which program responsiveness to the GLM could be enhanced.

Beyond Static and Dynamic Risk Factors The Incremental Validity of Release Planning for Predicting Sex Offender Recidivism

Carwyn Scoones; Gwenda M. Willis; Randolph C. Grace

Both desistance research and strengths-based approaches to offender rehabilitation suggest that attempts to reduce sex offender recidivism should attend to an offender’s release environment. Recent research has demonstrated that better quality release planning is associated with reduced recidivism; however, whether release planning contributes significant incremental validity in predicting recidivism over and above static and dynamic risk factors is unclear. In the present study, release planning was retrospectively assessed for a sample of child molesters (n = 196) who had been released into the community following completion of a prison-based treatment program and its relative contribution to recidivism risk prediction was investigated. The average follow-up period was 11.08 years, during which 13.3% of the sample were convicted of a new sexual offence. Hierarchical Cox regression analyses showed that release planning contributed additional predictive validity for sexual recidivism after controlling for static and dynamic risk factors. Findings suggest that assessment of release planning might improve accuracy of sex offender risk assessments and that improved release planning should contribute to reductions in recidivism.

Adverse Childhood Experiences in the Lives of Female Sex Offenders

Jill S. Levenson; Gwenda M. Willis; David S. Prescott

This study explored the prevalence of early trauma in a sample of U.S. female sexual offenders (N = 47) using the Adverse Childhood Experiences (ACE) scale. Compared with females in the general population, sex offenders had more than three times the odds of child sexual abuse, four times the odds of verbal abuse, and more than three times the odds of emotional neglect and having an incarcerated family member. Half of the female sex offenders had been sexually abused as a child. Only 20% endorsed zero adverse childhood experiences (compared with 35% of the general female population) and 41% endorsed four or more (compared with 15% of the general female population). Higher ACE scores were associated with having younger victims. Multiple maltreatments often co-occurred in households with other types of dysfunction, suggesting that many female sex offenders were raised within a disordered social environment by adults with problems of their own who were ill-equipped to protect their daughters from harm. By enhancing our understanding of the frequency and correlates of early adverse experiences, we can better devise trauma-informed interventions that respond to the clinical needs of female sex offender clients.

Demographic Differences in Public Attitudes Towards Sex Offenders

Gwenda M. Willis; Sanna Malinen; Lucy Johnston

Emotionally fueled public responses to news of released sex offenders have the potential to jeopardize the re-entry process, for example, hindering access to stable housing and employment opportunities. Influencing change in public attitudes towards sex offenders so that they are conducive to successful community re-entry is important in efforts to prevent recidivism. Maximizing the effectiveness of attempts to change public attitudes first requires identifying whether specific demographic groups are more prone to negative attitudes, so that attempts to change attitudes can be appropriately targeted. In the present study, 401 community members completed an online questionnaire designed to assess the affective, cognitive and behavioral dimensions of attitudes towards sex offenders. Differences in attitudes towards sex offenders based on respondent sex, age, educational attainment, occupation, parental status and familiarity with victims and perpetrators of sexual assault were investigated. Females demonstrated more-negative attitudes on affective and behavioral measures compared with males, and respondents with low levels of educational attainment demonstrated more-negative attitudes than respondents with higher levels of educational attainment on cognitive and behavioral measures; however, all groups demonstrated negative attitudes towards sex offenders to some extent. Implications for community-level interventions that promote effective re-entry, and hence reduce the likelihood of sexual reoffending are discussed.

The Rehabilitation of Offenders: Reducing Risk and Promoting Better Lives

Clare-Ann Fortune; Tony Ward; Gwenda M. Willis

This article examines the nature of offender rehabilitation and briefly reviews the effectiveness of correctional interventions in reducing recidivism. It then outlines the two most prominent contemporary theories of offender rehabilitation: the Risk-Need-Responsivity Model and the Good Lives Model (GLM). Our aim is to introduce these two broad rehabilitation frameworks and analyse their practice implications. We conclude that the GLM can offer an alternative view of offender rehabilitation that seeks to help offenders live more fulfilling lives while also reducing risk.

Current re-entry practices in sex offender treatment programmes: desistance facilitating or hindering?

Svenja Göbbels; Gwenda M. Willis; Tony Ward

Abstract Little is known about current re-entry practices, nor the extent to which they facilitate re-entry, reintegration and, ultimately, desistance from future offending. Göbbels, Ward and Willis recently developed the Integrative Theory of Desistance from Sex Offending (ITDSO), which comprehensively describes the individual desistance process in four phases. In the current research, the re-entry phase of the ITDSO was used as a theoretical framework to evaluate current re-entry practices in five North American sex offender treatment programmes. Inductive thematic analyses were conducted using interview data from programme directors and final client assignments. Eleven themes were identified. Findings are discussed in relation to their fit with the ITDSO and suggestions are made for improving re-entry practices so that they better promote desistance.
