Causal Interpretations of Correlational Evidence Regarding Violence.

Inferring causation from correlation can lead to erroneous explanations of violent behavior and the development and implementation of ineffective or even harmful interventions and policies. This article explores the inferences that violence researchers draw from evidence related to violent offending. We invited authors of articles published in violence journals to complete an online survey in which they were asked to identify a factor that may be a cause of violence, cite a study that demonstrates the factor is associated with violence, and provide their inferences from that study. We read each study and coded its research design (description of a sample [n = 9], cross-sectional/retrospective non-experiment [n = 18], single-wave longitudinal non-experiment [n = 10], multi-wave longitudinal non-experiment [n = 0], or randomized experiment [n = 5]) and the appropriate inferences (inter-rater reliability was adequate; κ = 0.73-1.00). Reassuringly, participants (N = 42; 57.1% in United States; 59.5% women) rarely indicated that their identified study demonstrated that their factor was a cause of violence (0.0%-16.7%) when the study was not a randomized experiment. However, many participants failed to acknowledge any plausible alternate interpretations (e.g., reverse causality, third variable) of the results from non-experimental studies (50.0%-88.9%). Moreover, most participants incorrectly selected a causal implication as following from the results of non-experimental studies (77.8%-100%). Our results suggest that even among authors of articles published in peer-review scientific journals on violence, many appear to infer causation from correlation.

Violent attitudes in Portugal and Canada: Measurement invariance and psychometric properties of the Evaluation of Violence Questionnaire.

Theory and evidence suggest that attitudes toward violence are relevant for the explanation, prediction, and reduction of violent behavior. The purpose of the present study was to adapt a measure of violent attitudes-the Evaluation of Violence Questionnaire (EVQ)-for use in Portugal, test the cross-country equivalence, and test the validity of both versions. We found the expected one-factor structure, high internal consistency, and cross-country measurement invariance for the Portuguese and original EVQ with men in Portugal (N = 320) and Canada (N = 298). We also found the expected pattern of correlations with measures of more versus less theoretically relevant constructs: both versions of the EVQ showed the strongest correlations with overall aggression and reactive aggression; slightly lower correlations with proactive aggression; negative correlations with self-control; and the smallest correlations with self-esteem. Our results support the equivalence, reliability, and validity of the Portuguese and original versions of the EVQ.

Using reaction time procedures to assess implicit attitudes toward violence in a nonconvicted male sample.

In this study, we sought to capture implicit attitudes toward violence by administering response latency measures. We then examined their associations with explicit (e.g., assessed with self-report) attitudes toward violence and self-reported violent behavior in a combined sample of males from a Canadian university and males from the general community (N = 251; 156 students and 95 community members). To date, there have been mixed findings regarding these associations; some of this inconsistency may be due to the difficulty in accurately conceptualizing and assessing implicit attitudes toward violence. Therefore, we administered three response latency measures to assess this construct: a violence evaluation implicit association test (VE-IAT), a personalized VE-IAT (P-VE-IAT), and a violence evaluation relational responding task, along with three self-report measures of explicit attitudes toward violence and three self-report measures of violent behavior. More positive implicit attitudes toward violence were related to more positive explicit attitudes toward violence (for VE-IAT and P-VE-IAT; r = 0.18 to 0.22), greater likelihood of violence (for VE-IAT; r = 0.18 and for P-VE-IAT; r = 0.16), and greater propensity for violence (for the VE-IAT; r = 0.16). All measures of explicit attitudes toward violence and violent behavior were moderately to strongly associated with one another (r = 0.42 to 0.81). Furthermore, implicit attitudes toward violence explained additional variance in some violent outcomes above explicit attitudes alone. Our findings suggest that scores on certain reaction time measures are important for understanding likelihood and propensity for violence, especially when combined with explicit attitude measures.

Exploring the Underlying Constructs of Rape-Related Cognition Scales and Their Relationships With Sexual Aggression.

Rape-related cognitions (typically defined as encompassing any number of cognitive constructs) are thought to play a role in sexual aggression. However, rape-related cognition scales often assess these cognitive constructs as one. The purpose of this study is to explore the factor structure of these measures using a sample of 191 community men. We found that items from the Rape Myth Acceptance, RAPE, and Illinois Rape Myth Acceptance (IRMA) scales formed one factor, which was significantly related to sexual aggression. We further found that four and six IRMA subscales were significantly related to past and likelihood of sexual aggression, respectively. Additionally, one IRMA subscale was independently related to past and likelihood of sexual aggression. The results are discussed in terms of implications and direction for future research.

Evaluative Attitudes May Explain the Link Between Injunctive Norms and Sexual Aggression.

The current study examined the extent to which evaluative attitudes toward sexual aggression (i.e., positive or negative evaluative judgments about sexually aggressive behavior) mediate the association between injunctive norms (i.e., extent to which peers approve or disapprove of sexually aggressive behavior) and self-reported sexual aggression against women. Participants were 200 male undergraduate students. Approximately one in four males reported engaging in at least one sexually aggressive act since the age of 16. Participants with a history of sexual aggression also reported the highest likelihood of engaging in sexually aggressive behavior in the future. We tested two separate mediation models to examine the extent to which evaluative attitudes account for the link between injunctive norms and sexual aggression: one model with self-reported history of sexual aggression as the outcome and the other with likelihood of engaging in sexually aggressive behavior as the outcome. Results showed that more positive evaluative attitudes toward sexual aggression accounted for the association between injunctive norms and self-reported history of sexual aggression. Similarly, evaluative attitudes accounted for the link between injunctive norms and self-reported likelihood of engaging in sexually aggressive behavior in the future. Overall, these findings are consistent with theoretical and empirical explanations of sexual offending and general criminal behavior; however, this is the first study to explore the relationship between injunctive norms and evaluative attitudes in the context of explaining sexually aggressive behavior. If more rigorous research establishes a causal relationship between injunctive norms, evaluative attitudes, and sexually aggressive behavior, this would suggest that targeting these factors in prevention programs may reduce sexual aggression by male undergraduate students.

How well do indirect measures assess sexual interest in children? A meta-analysis.

OBJECTIVE: We quantitatively reviewed the construct validity evidence for all cognitively based indirect measures of sexual interest in prepubescent children (pedophilic interest) and pubescent children (hebephilic interest) using meta-analysis. METHOD: Studies were included if they presented scores on a cognitively based indirect measure of pedohebephilic interest for a sample of adolescent or adult males who had committed a sexual offense against a child 16 years of age or younger, or who reported sexual interest in children, and for a comparison group. Studies were also included if they reported on the strength of association between scores on an indirect measure and an independent indicator of pedohebephilic interest in a sample of males. We used meta-analysis with robust variance estimation to summarize effect sizes and metaregression to test potential moderators. RESULTS: Cognitively based indirect measures of pedohebephilic interest showed a moderate difference between pedohebephilic (n = 2,552) and nonpedohebephilic males (n = 2,434), d = 0.61, 95% CI [0.46, 0.76], k = 39. A small-to-moderate correlation was also observed between indirect measures and independent indicators of pedohebephilic interest, r = .23, 95% CI [0.17, 0.28], k = 23, n = 3,623. These effects were qualified by substantial heterogeneity; however, most moderators we tested did not account for a significant amount of heterogeneity. CONCLUSIONS: Findings suggest that publication bias did not substantially distort the results. However, the lack of significant moderators suggests more research is needed to understand the conditions under which indirect measures best reflect pedohebephilic interest.

Disentangling Cognitions About Sexual Aggression.

We examined the extent to which evaluative attitudes toward sexual aggression are distinct from other cognitions regarding sexually aggressive behavior. Evaluative attitudes toward sexual aggression refer to the extent to which sexual aggression is viewed negatively or positively. In a secondary analysis of online survey data from 495 community men, exploratory factor analysis revealed that items from a measure of evaluative attitudes formed a distinct factor from items designed to measure cognitive distortions regarding rape. These findings suggest that evaluative attitudes may be distinct from cognitive distortions. Furthermore, hierarchical regression analyses indicated that evaluative attitudes explained unique variance in self-reported past sexual aggression, proclivity for sexually aggressive behavior, and likelihood to rape. If future research finds support for a causal relationship between evaluative attitudes and sexual aggression, well-established evaluative-attitude-change procedures from the social psychological literature could be adapted to address evaluative attitudes toward sexual aggression in interventions aimed at reducing sexually aggressive behavior.

The Violent Behavior Vignette Questionnaire (VBVQ): A Measure of Violent Behavior for Research in Forensic and Non-Forensic Settings and Populations.

The measurement of violent behavior presents serious challenges for research on violence. In the current article, we present initial tests of the construct validity of scores on the Violent Behavior Vignette Questionnaire (VBVQ), which consists of a series of interpersonal conflict vignettes with response options in a multiple-choice format designed to measure current violent behavior. Violent responses on the initial version of the VBVQ generally corresponded to independent indicators of physical aggressiveness and violent behavior among male university students, men in the community, and incarcerated male offenders. We then refined the VBVQ and again tested the validity of its scores in new samples of men in the community and incarcerated male offenders. In both samples, men who selected a violent response option on the VBVQ generally had much higher levels of physical aggressiveness and violent behavior than did men who selected non-violent response options. However, VBVQ responses were not associated with the number of violent offenses in offenders' official criminal records. Our findings provide some support for the use of the VBVQ in lab and correctional/forensic research, but further research is required to determine whether it offers advantages over other measures.

Explicit and Implicit Self-Esteem, Narcissism, and Recidivism Risk in a Sample of Men Who Have Sexually Offended Against Children.

The relationship between implicit and incongruent explicit and implicit (i.e., discrepant) self-esteem, narcissism, and sexual offending against children requires further research. We examined the relationships between self-esteem, narcissism, and risk of violent (including sexual) recidivism and compared sexual offenders against children (n = 28) and non-sexual offenders (n = 44) on these measures. All participants were adult men. In both groups, greater narcissism was associated with greater risk. Among sexual offenders against children, contrary to theoretical accounts and previous research findings, higher explicit self-esteem was associated with greater risk. However, further analysis indicated that explicit self-esteem may only be relevant to recidivism risk insofar as it reflects narcissism. Neither implicit nor discrepant self-esteem were related to recidivism risk in either group. Group comparisons indicated that sexual offenders against children had lower explicit self-esteem and narcissism than non-sexual offenders. In summary, our findings suggest that although sexual offenders against children have lower explicit self-esteem and narcissism than other offenders, within this group, higher explicit self-esteem and greater narcissism may be associated with greater risk. Taken together, previous and current findings suggest that including measures of narcissism in psychological assessment batteries administered to sexual offenders against children could be beneficial. Our findings also further question the wisdom of targeting low self-esteem in correctional treatment programs aimed at reducing recidivism.

Validity in Phallometric Testing for Sexual Interests in Children: A Meta-Analytic Review.

Valid assessment of pedohebephilic interests (i.e., sexual interest in children) is fundamental to forensic clinical practice. Phallometric testing-which measures changes in penile circumference or volume, while stimuli depicting different ages and sexual activities are presented-is widely used in clinical and research settings to detect such interests. This meta-analysis summarizes studies comparing sexual offenders against children and various types of controls on phallometric tests for pedohebephilic interests (37 samples; N = 6,785) and studies examining the relationship between phallometric test scores and sexual reoffending (16 samples; N = 2,709). The findings suggest that several phallometric testing procedures are valid indicators of pedohebephilic interest. Certain methodological features of phallometric tests were associated with greater validity, such as, slide or audio-plus-slide stimuli and z-score-based indices. In addition, phallometric tests for pedohebephilic, pedophilic, and hebephilic interests predicted sexual reoffending which provides further evidence that phallometric test scores are valid indicators of sexual interest in children. In general, the interpretation of phallometric test scores as indicators of pedohebephilic interests is supported.

"I Know Correlation Doesn't Prove Causation, but . . .": Are We Jumping to Unfounded Conclusions About the Causes of Sexual Offending?

Identifying causes of sexual offending is the foundation of effective and efficient assessment, intervention, and policy aimed at reducing sexual offending. However, studies vary in methodological rigor and the inferences they support, and there are differences of opinion about the conclusions that can be drawn from ambiguous evidence. To explore how researchers in this area interpret the available empirical evidence, we asked authors of articles published in relevant specialized journals to identify (a) an important factor that may lead to sexual offending, (b) a study providing evidence of a relationship between that factor and sexual offending, and (c) the inferences supported by that study. Many participants seemed to endorse causal interpretations and conclusions that went beyond the methodological rigor of the study they identified. Our findings suggest that some researchers may not be adequately considering methodological issues when making inferences about the causes of sexual offending. Although it is difficult to conduct research in this area and all research designs can provide valuable information, sensitivity to the limits methodology places on inferences is important for the sake of accuracy and integrity, and to stimulate more informative research. We propose that increasing attention to methodology in the research community through better training and standards will advance scientific knowledge about the causes of sexual offending, and improve the effectiveness and efficiency of practice and policy.

Emotional Congruence with Children: Are Implicit and Explicit Child-Like Self-Concept and Attitude Toward Children Associated with Sexual Offending Against Children?

Some men convicted of sexual offences against children express an exaggerated affiliation with childhood, ascribe child-like characteristics to themselves, experience strong non-sexual liking of children, and hold positive views of children and childhood. These features are generally called emotional congruence with children. The present study examined child-like self-concept, which is an association of self with children and child-like characteristics, attitude toward children, and general emotional congruence with children as correlates of sexual offending against children and pedophilia. Male participants (18 sexual offenders against unrelated children; 7 incest offenders; 22 non-sexual offenders; 54 students) completed newly developed implicit and explicit measures of child-like self-concept and attitude toward children, as well as more established self-report measures of emotional congruence with children. Assessments of pedophilic interest and sexual recidivism risk were obtained from official file information. Sexual offenders against unrelated children reported higher levels of implicit child-like self-concept and self-reported emotional congruence with children when compared to the other three groups. Implicit child-like self-concept showed a small correlation with emotional congruence measures, whereas implicit attitude toward children was moderately correlated with the emotional congruence measures. Implicit child-like self-concept, implicit attitude toward children, and the emotional congruence measures were associated with greater pedophilic interest and sexual recidivism risk. The present findings provide a nuanced understanding of the emotional congruence with children construct and have implications for theory, research, and treatment of sexual offenders against children.

Attitude May Be Everything, But Is Everything an Attitude? Cognitive Distortions May Not Be Evaluations of Rape.

Cognitive distortions are often referred to as attitudes toward rape in theory, research, and clinical practice pertaining to sexual aggression. In the social-psychological literature, however, attitudes are typically defined as evaluations; thus, in this context, attitudes toward rape are considered evaluations of rape (e.g., rape is negative vs. positive). The purpose of the current study was to explore whether a widely used measure of cognitive distortions (RAPE Scale; Bumby, 1996) assesses evaluation of rape, and, if not, whether evaluation of rape and the cognitions assessed by the RAPE Scale are independently associated with sexually aggressive behavior. Participants (660 male undergraduate students) completed the RAPE Scale as well as measures of evaluation of rape and sexually aggressive behavior. An exploratory factor analysis revealed that the RAPE Scale items formed a correlated but distinct factor from the Evaluation of Rape Scale items. Regression analyses indicated that the Evaluation of Rape Scale and the RAPE Scale had small to moderate independent associations with self-report measures of sexually aggressive behavior. Our results suggest that evaluation of rape may be distinct from cognitive distortions regarding rape, and both evaluation and cognitive distortions may be relevant for understanding sexual violence.

Examining Implicit and Explicit Evaluations of Sexual Aggression and Sexually Aggressive Behavior in Men Recruited Online.

The purpose of the current study was to explore the relationship between implicit and explicit evaluations of sexual aggression and indicators of sexually aggressive behavior in samples of students and community men recruited online. Participants were male undergraduate students recruited online from a Canadian University ( N = 150) and men recruited from the community via an online panel ( N = 378). Participants completed measures of implicit and explicit evaluations of sexual aggression, cognitive distortions regarding rape, self-reported past sexually aggressive behavior, and self-reported proclivity to commit sexually aggressive behavior. We found that more positive explicit evaluations and more cognitive distortions were moderately to strongly associated with sexual aggression; however, this was not the case for implicit evaluations of rape. Our results suggest that explicit evaluations of sexual aggression and cognitive distortions may be relevant for understanding sexual aggression against adults, and that more research is needed exploring whether or not implicit evaluations are associated with sexually aggressive behavior.

Implicit and Explicit Evaluations of Sexual Aggression Predict Subsequent Sexually Aggressive Behavior in a Sample of Community Men.

The current longitudinal study explored the extent to which implicit and explicit evaluations of sexual aggression predict subsequent sexually aggressive behavior. Participants (248 community men recruited online) completed measures of implicit and explicit evaluations and self-reported sexually aggressive behavior at two time points, approximately 4 months apart. Implicit and explicit evaluations of sexual aggression at Wave 1 had small significant and independent predictive relationships with sexually aggressive behavior at Wave 2, while controlling for sexually aggressive behavior at Wave 1. This is the first study to test whether implicit and explicit evaluations predict subsequent sexually aggressive behavior. Our findings are consistent with the possibility that both implicit and explicit evaluations may be relevant for understanding and preventing subsequent sexually aggressive behavior. If these findings can be replicated, evaluations of sexual aggression should be studied with more rigorous methodology (e.g., experimental design) and correctional/forensic populations, and possibly addressed in risk assessment and interventions.

The Factor Structure of the Aggression Questionnaire With Violent Offenders.

The Buss-Perry Aggression Questionnaire (AQ) is a self-report measure of aggressiveness commonly employed in nonforensic and forensic settings and is included in violent offender pre- and posttreatment assessment batteries. The aim of the current study was to assess the fit of the four-factor model of the AQ with violent offenders ( N = 271), a population for which the factor structure of the English version of the AQ has not previously been examined. Confirmatory factor analyses did not yield support for the four-factor model of the original 29-item AQ. Acceptable fit was obtained with the 12-item short form, but careful examination of the relationships between the latent factors revealed that the four subscales of the AQ may not represent distinct aspects of aggressiveness. Our findings call into question whether the AQ optimally measures trait aggressiveness among violent offenders.

Are Child Abusers Sexually Attracted to Submissiveness? Assessment of Sex-Related Cognition With the Implicit Association Test.

Child sexual abuse is associated with social anxiety, low self-esteem, and intimacy deficits. This, in combination with the core belief of a dangerous world, might suggest that child abusers are sexually attracted to submissiveness. The Implicit Association Test (IAT) was used to examine this hypothesis. Results indicated that child abusers have a stronger sexual preference for submissiveness than rapists, although there were no differences between child abusers and non-sexual offenders. Multinomial logistic regression analysis revealed that submissive-sexy associations have incremental value over child-sex associations in differentiating child abusers from other offenders. The predictive value of both implicit associations was explored by correlating IAT scores with measures for recidivism risk, aggression, and interpersonal anxiety. Child abusers with stronger child-sex associations reported higher levels of interpersonal anxiety and hostility. More research on implicit cognition in sex offenders is required for a better understanding of what these and similar implicit measures are exactly measuring and what role implicit cognition may play in sexual offending.

Does Change on the MOLEST and RAPE Scales Predict Sexual Recidivism?

The purpose of the current study was to examine whether the MOLEST and RAPE scales and change on these measures predicted sexual recidivism in a sample of 146 adult male sexual offenders who participated in a high-intensity treatment program while incarcerated. The majority of subjects had functional scores on the MOLEST and RAPE scales prior to treatment. Of those who had dysfunctional pre-treatment scores, the majority made significant gains. However, the MOLEST and RAPE scales did not significantly predict sexual recidivism. This was the case for pre-treatment scores, post-treatment scores, and change scores. Our findings are generally not consistent with the view that these measures assess dynamic risk factors for sexual recidivism. However, this is the first published study to examine the predictive validity of these scales and more rigorous research is needed before firm conclusions can be drawn.

Does change in hostility predict sexual recidivism?

The purpose of the study was to examine whether scores on a widely used measure of hostility--the Buss-Durkee Hostility Inventory (BDHI)--and change on this measure predicted sexual recidivism in a sample of 120 adult male incarcerated sexual offenders. Pre- and posttreatment scores, simple difference scores, and clinically significant change were examined. The majority of participants had functional scores on the BDHI prior to treatment. Of those who had dysfunctional pretreatment scores, the majority remained unchanged. Higher posttreatment scores on the Assault and Verbal Hostility subscales significantly predicted sexual recidivism. The remaining pre- and posttreatment scores as well as change scores and classifications did not significantly predict sexual recidivism. Our findings suggest that the Assault and Verbal Hostility subscales may be useful for predicting sexual recidivism but were not clearly consistent with the notion that the BDHI assesses a dynamic risk factor(s) for sexual recidivism. Due to a number of limitations of the current study, however, more rigorous research is needed before firm conclusions can be drawn.
