Overview of Talk Raymond Knight Rutgers Conference, 2014
Raymond Knight Rutgers Conference, 2014 Violence, Mental Health, and Communities, 2014 The Etiology and Primary Prevention of Rape Raymond A. Knight, Ph.D. Overview of Talk ² Effective prevention requires a valid etiological model. ² I will present a promising model and draw out its implications for developing effective prevention programs. Part II I will integrate these traits into both their known developmental antecedents and the potential genetic predispositions of these traits that interact with early experience. Preventing Rape Overview of Talk ² This talk is a polemic for the primary prevention of rape. ² I will argue that current prevention programs have been suboptimal because they focus on the correlates and not the causes of rape. Part I 1. I will set up the polemic by critically evaluating current prevention models and arguing that they may be focusing on correlated components of sexual aggression and not core causes. 2. I will present an overall causal model that integrates the extant research on the traits related to a proclivity for sexually coercive behavior. 3. I will integrate into this model the research on the concurrent correlates of rape proclivity. 4. I will then unpack nature of the traits. Part III I will draw out the implications of the proposed etiological model for treatment and recommend modifications for prevention strategies. 1 Raymond Knight Rutgers Conference, 2014 Common Target of Programs Part I (a) Evaluation of Current Prevention Strategies Most have been targeted acquaintance rape and have applied a skills-based approached aimed at improving sexual relationship knowledge and dating behavior and countering rape-supportive attitudes (Gidycz, Orchowski, & Edwards, 2011). Overall Results Anderson & Whiston, 2005 0.9 0.8 Rape Knowledge 0.7 Meta-analysis of 69 studies 102 treatment interventions 18,172 participants 0.6 Rape Attitudes Rape Empathy Rape Attitudes Rape Knowledge Behavioral Intent Awareness Behavior Incidence 0.5 0.4 0.3 Rape Attitudes 0.2 Incidence 0.1 0 Conclusion on Rape Incidence If effectiveness is defined solely as a decrease in sexual assault, then there is little support available from the current pool of studies. Anderson & Whiston, 2005 Preventing Rape Outcome Categories Recommended New Directions ² Develop longer, more comprehensive, multi-level prevention strategies that include peer, community, and societal levels. ² Intervene earlier, in high schools. ² Focus on by-stander interventions. ² Attempt to impact the social context. 2 Raymond Knight Rutgers Conference, 2014 Alternatively ² Historically, primary prevention programs have depended on empirically validated etiological models. ² Interventions that target causes rather than correlates have greater potential for success. ² Moffitt (2005) – Aggression literature is littered with prevention programs that do not work, because they target correlates. ² To be successful we must determine the best etiological/causal models. ² Generate recommendations for intervention from the model. Part I (b) Current Correlates and Hypothetical Traits of Rape Validation Etiology SEM Model Replicated • College Students (Johnson & Knight, 1998) • Community non-criminal controls (Knight & Sims-Knight, 2003) • Generic non-sexual criminals (Johnson & Knight, 1998) • Juvenile Sexual Offenders (Knight & SimsKnight, 2004) (Knight & Sims-Knight, 2003) Validation Recent Developments in the Etiology Model Traits Consistent with • College Students (Malamuth, 2003; Abbey, Jacques-Tiura, & LeBreton, 2011) • Representative Sample of Adolescent Males (Casey, Beadnell, & Lindhorst, 2009) • Generic Sex Offenders (Lussier, LeClerc, Cale, & Proulx, 2007) Preventing Rape 3 Raymond Knight Rutgers Conference, 2014 Recent Additional Developmental Antecedents in the Etiology Model Merging of CM and Hypersexuality MTC:R4 Transformation from the Etiological to the Typological Model H h ig t Ex Lo w MTC:R4 Psychopathic" ing gh Hi Ex te a rn liz s/ High Callou (CM) Manipulative Hi gh Se x Mod S.C.! ua liz at io n Vindictive!

Concurrent Correlates Morton-Bourgon, 2005, 2009; Knight & Thornton, 2007, 2014). Concurrent Correlates ? Alcohol Use Alcohol Use and Abuse Alcohol Use • Plays multifaceted role in rape (Abbey, Distorted Perceptions Zawacki, Buck, Clinton, & McAuslan, 2004; Prentky & Knight, 1991). Sexual Coercion • In 50% of sexual assaults-v the perpetrator has been drinking (Abbey et al., 2004). Rape Attitudes v the victims have been found to be using alcohol Pornography Use Alcohol Use and Abuse v Impairs inhibitory controls; v Exacerbates communication misinterpretations; v Disrupts of higher order cognitive processing; and v Interacts with existing personality characteristics (e.g., trait aggression)-- (Abbey et al., 2004). Alcohol Use and Abuse Results in – v increased frequency and recidivism of sexual coercion (Abbey, Wegner, Pierce, & Jacques-Tiura, 2012), v increased violence in the assault (Hamdi & Knight, in press; Abbey et al., 2003), v curvilinear relation to the severity of outcome (i.e., whether coitus is achieved) (Abbey et al., 2003). All interface with sexually coercive behavior Preventing Rape Also, victim alcohol consumption covaries with a greater risk of completed rape. 5 Raymond Knight Rutgers Conference, 2014 Distorted Perceptions Traits ? ? ? Alcohol Use • Covaries with the Externalizing Spectrum (Krueger, Hicks, Patrick, Carlson, Iacono, & McGue, 2002). • Covaries with the PCL Impulsivity/ Antisocial Behavior Factor (Factor 1), • But not with the PCL AffectiveInterpersonal Characteristics Factor (Factor 2) (Taylor & Lang, 2006). Distorted Perceptions Distorted Perceptions • • Rape, especially acquaintance rape, occurs within a social context that requires the active selection and processing of information. Multiple studies have suggested that males who are likely to rape may have perceptual biases that lead to specific misperceptions of women s communications (Abbey, 1982, 1987). Distorted Perceptions § Drieschner and Lange (1999) -- three hypothetical classes of perception-§ the tendency to over-perceive § § friendly behavior as seductive and assertive behavior as hostile; § in ambiguous situations a positivity bias that transforms negative, dismissive communications into encouragement; and § a general set to mistrust women s communications and perceive them as hostile. Traits ? ? ? The over-perception of sexual intent in women's behavior has received the greatest empirical support (Farris, Treat, Viken, & McFall, 2008). Distorted Perceptions Method Non-Task Condition Method – Attentional Study 36 undergraduates at a northeastern university Shape Tasks: v Short form of the Multidimensional Inventory of Development, Sex, and Aggression (the MIDSA) v Cognitive disattention task.

Hostility Toward Women MIDSA (MIDSA, 2011;Knight & Sims-Knight, 2003) Pornography Use Pornography Use Pornography Use Two meta-analyses establish a moderate correlation between porn use and sexual coercion (Hald, Malamuth, O Connor, & Yuen, 2008; Oddone-Paolucci, Genius, & Violato, 2000). Sexual Coercion The same risk factors like high sexual fantasy, sociosexuality, dominance, hypermasculinity, etc. predict both porn use and rape (Kingston, Malamuth, Fedoroff, & Marshall, 2009; Malamuth, Addison, & Koss, 2000). Risk Factors Sexual Coercion ? Pornography Use Traits ? ? ? Pornography Use Pornography Use Exposure to sexual materials is more likely to increase rape proclivity in those who are high on these common risk factors (Kingston et al., 2009; Malamuth, & Huppin, 2005).

(Teicher, Samson, Polcari, & McGreenery, 2006) Genetic Variation and Environment Vulnerable Resilient Maladaptive Adaptive Getting from Genes to Behaviors MAOA gene • Encodes the MAOA enzyme that metabolizes neurotransmitters such as norepinephrine, serotonin, and dopamine. • Variation in this gene results in higher or lower MAO activity. • Lower MAO activity is related to increased aggressive behavior. • A meta-analysis has corroborated MAOA gene by environment effects on aggression (Kim-Cohen et al., 2006). Preventing Rape Focus • Single genes that help us to specify the effects of genes on behavior. • Gene by environment interactions that confirm the importance of nature and nurture . • Lesson – Some genes are expressed only when they encounter deleterious environments. – They are not a death sentence. Edwards, Dodge, et al., 2009 Child Development Longitudinal Project • Community sample followed from age 5 to 22; • Examined in males the effects of physical abuse and presence of variant alleles of the MAOA gene. 15 Raymond Knight Rutgers Conference, 2014 MAOA Buffers Effect of Abuse on Arrest % Arrested by Age 22 80 70 60 50 Low MAOA High MAOA 40 30 20 10 0 No Overall Summary of Etiology Findings • Early stress -> prevalent and harmful among sex offenders. • Types of abuse -> differential effects. • Genetic component involved in both externalizing and internalizing syndromes. • Genes interact Yes Early Physical Abuse (Edwards, Dodge, et al., 2009) More Summary and Treatment Implications Sexual Abuse Hypersexuality, Anx & Dp Emotional & Physical Abuse Anger, Hostility, Delinquency Traits in Etiological Model Sexual Coercion Part III Recommendations for Treatment and Prevention Strategies Targets of Intervention TREATMENT Implications TREATMENT Implications Key Dynamic Recidivism Predictors Core Traits Externalizing Self-Management Criminality Antisociality Impulsivity Externalizing Callous/ Manipulative Callousness Grievance Thinking Callous/ Manipulative Hypersexuality Sexualization Sex Deviance Sex Attitudes Hypersexuality Core Traits Preventing Rape Map Onto Map Onto Key Dynamic Recidivism Predictors Self-Management Criminality Antisociality Impulsivity Andrews & Bonta (2006) (R/N/R) Needs Principle Treatment Targets, replicated for Sex Offenders (Hanson et al., 2009) Callousness Grievance Thinking Sexualization Sex Deviance Sex Attitudes 16 Raymond Knight Rutgers Conference, 2014 Types of Prevention Strategies • UNIVERSAL strategy -- Intervening in a general way in the population with a generic program. • SELECTED strategy -- Intervening in a sample that is known to have a high base rate for the particular problem. • INDICATED strategy – Intervening with individuals who have the prodromal signs of a disorder, but have not yet crossed the line.

Conclusions • Thus, our etiological model proposes a difference in perspective on prevention than that currently in vogue. • The data we have presented call for the concerted research effort that is necessary to maximize the efficacy of prevention interventions. Conclusions • We must advocate for – – the etiology research that will maximize their efficacy of our interventions efficacy, and – the implementation research that will test this efficacy. • In the long run prevention is not only the route that will most effectively minimize the pain and suffering of victims, it also will prove to be the most cost effective solution to the problem of violence.
