Predicting perceptions of date rape: an examination of perpetrator motivation, relationship length, and gender role beliefs

The purpose of the current study is to examine the influence of multiple offender motivations (including no indication of a motivation), relationship length, and gender role beliefs on perceptions of a male-on-female date rape. A sample of 348 U.S. college students read a brief vignette depicting a date rape and completed a questionnaire regarding their attributions about the victim (culpability, credibility, trauma, pleasure) and perpetrator (culpability, guilt, sentencing recommendations). Results indicate that providing observers with information about the perpetrator's motivation was associated with lower victim blame. Relationship length is not predictive of rape attributions. Egalitarian gender role attitudes are associated with lower levels of victim blame. Overall, gender role attitudes exert a more significant influence on rape attributions than participant gender. The findings suggest that knowledge of an offender's motivation as well as observers' gender role attitudes can influence attributions about the culpability of victims and perpetrators of date rape.     

Effectiveness of citizen police academies in changing the attitudes, beliefs, and behavior of citizen participants

The purpose of this study was to determine whether the citzen police academies (CPA) in two cities were effective in changing participants’ attitudes, beliefs, and behavior toward police. Pre-and post-test questionnaires were used to obtain participants’ ratings of their attitudes and beliefs concerning police officers and their willingness to cooperate with police. Participants were also asked to indicate what cooperative behaviors they had actually engaged in before and/or during the CPA. At the end of the CPA, participants in both cities rated themselves as having more positive attitudes toward police, and more willingness to engage in behaviors that would help police. There was also an increase in actual performance of some cooperative behaviors during the CPA. These changes did not seem to be overly dependent on the jurisdiction (large versus small city), the demographics of the CPA participants, or the specific characteristics of the CPA curriculum.     

Measuring the validity and reliability of forensic likelihood-ratio systems

There has been a great deal of concern recently about validity and reliability in forensic science. This paper reviews for a broad target audience metrics of validity and reliability (accuracy and precision) which have been applied in forensic voice comparison and which are potentially applicable in other branches of forensic science. The metric of validity is the log likelihood-ratio cost (C_llr), and the metric of reliability is an empirical estimate of credible intervals. A revised procedure for the calculation of credible intervals is introduced.     

Reassessing the reliability and validity of self-report delinquency measures

Several issues related to the reliability and validity of self-report delinquency measures are raised and discussed. These include problems associated with the use of internal consistency as the measure of reliability, the level of reliability or precision required for different types of analyses, problems with the content validity of self-report measures, problems of overreporting and underreporting, problems with the use of official records as a validity check on self-reports, and the lack of any good criterion as a major obstacle in assessing the empirical validity of self-report measures. In the light of these problems, some cautions about the use of self-report measures are made.     

Problems of reliability and validity in criminal justice research

Reliability and validity are critical standards of scientific inquiry. This analysis directs attention to problems of reliability in data collection and to problems of validity in measuring two key criminal justice variables: the offense and the sentence. The discussion and empirical analysis indicate that reliability of official information sources in criminal justice cannot be assumed. Furthermore, there is evidence to suggest that the criterion of validity is even more elusive. This elusiveness is demonstrated in the operational definition of criminal offense, an important predictor variable, and in attemps to operationally define the criminal sanction, i.e., the disposition of charges against convicted defendants. These considerations suggest that research in the sentencing area may not be directed to the subject at hand and that research results should be interpreted with “scientific” caution.     

The development and initial validation of the dating attitudes inventory: a measure of the gender context of dating violence in men

The development and initial psychometric investigation of the Dating Attitudes Inventory (DAI) is reported. The DAI was created, to fill a gap in the literature and to measure specific masculine ideology and traditional gender attitudes that rationalize the abuse of women. Using a sample (n = 164) of male college students, a 20-item measure was developed consisting of two subscales (Rationalization of Abuse and Dominance and Control) and a total score. The 20-item DAI and other measures used for validation were completed by 216 male college students. The DAI correlated in theoretically expected ways with measures of propensity for abusiveness, relational dominance, and masculine gender role stress. A confirmatory factor analysis supported the two theorized factors of the DAI. Results of the present study offer initial support for the validity and reliability of the DAI. The authors discuss the importance of measuring masculine gender role attitudes and beliefs that support and rationalize dating violence.     

Reliability and validity of the original and revised legal attitudes questionnaire

The Legal Attitudes Questionnaire (LAQ) predicts juror bias, but there is little evidence concerning its reliability and construct validity. Two studies provide such evidence for two versions of the LAQ. In Study 1 a questionnaire containing both versions of the LAQ, measures of related and unrelated constructs, and demographic questions was completed by 294 undergraduates. In Study 2 a shortened questionnaire was completed by 102 jury-eligible adults. In both studies, the revised version of the LAQ was superior to the original LAQ in terms of missing data, internal reliability, and construct validity. A refined version of the revised scale is presented, evaluated, and recommended for future use.This article is an expanded version of a poster presented at the meeting of the American Psychology and Law Society in March, 1992. We are grateful to Barbara Martin and Ray Wolfe for their comments on a previous version of this article. We would like to thank Sean Henriques, Tracy Chavez, Jennifer Devenport, Alex Milov, and Cathy Mucha for their assistance in data acquisition, entry, and verification. Finally, we thank the Miami Beach Kiwanis for participating in this study.     

Construct validity,reliability and predictive validity of the dynamic risk assessment and management system (DRAMS) in offenders with intellectual disability

Background. There have been a number of developments in the assessment of dynamic risk in the criminological literature. The dynamic risk assessment and management system (DRAMS) has been developed to facilitate the measurement of dynamic factors of risk for offenders with intellectual disability. Method. The study was designed to assess the construct validity, reliability and predictive utility of the DRAMS in 23 male forensic patients in a high secure setting. Predictions were made against independently collected incident data. Concurrent validity was assessed against the Ward Anger Rating Scale (WARS). Results. A reformulation of the individual section variables according to convergent and discriminant correlational analysis revealed Cronbach's alpha levels of >.8 for all sections apart from mood (alpha .750) and items retained to facilitate clinical information (alpha ?.017). Two hundred pairs of WARS and DRAMS assessments revealed orderly sectional correlations. The sections of mood, antisocial behaviour, and intolerance/agreeableness predicted incidents with a medium effect size as did total DRAMS score. There were highly significant differences between assessments taken 1 or 2 days prior to an incident and control assessments conducted at least 7 days from an incident. Conclusions. The reformulated DRAMS has good construct and concurrent validity. It appears to be a reliable assessment tool and informs on risk levels relating to stable and acute proximal factors. It appears as an important addition to the utility of risk assessments for this population.     

Rape myth beliefs and prejudiced instructions: Effects on decisions of guilt in a case of date rape

Purpose. The purpose of this study was to investigate the potential effects of pro and anti rape myth bias in judges' summing up statements on verdicts given by individuals. Method. A convenience sample of 90 male and 90 female students from a British university completed the Rape myth acceptance (RMA) scale ( Burt, 1980 ). A scenario depicting a date rape was read, ending with guidance that was either pro or anti rape myth, or neutral. Results. Rape myth supporting guidance was associated with innocent verdicts, and anti rape myth guidance with guilty verdicts, regardless of degree of rape myth acceptance. Level of rape myth acceptance and gender were also found to predict verdict. Conclusion. Rape myth biased guidance may influence verdicts in a rape scenario in which the attribution of blame to the man and woman depicted could be perceived as being ambiguous.     

Assessing reliability, validity, and clinical utility of the BEST-Index in measuring living skills among forensic inpatients

The assessment of behavioral change as a result of inpatient treatment in forensic psychiatry is an important precondition for violence risk prediction in forensic psychiatry. In relation to a multitude of diagnostically based risk assessment instruments, there is a shortage of appropriate instruments with which to carry out valid and reliable therapeutic assessments that are behaviorally based and therefore appropriate for use within varied psychiatric contexts. There is also a need for instruments which will offer assessors the opportunity to examine possible relationships between criteria of social risk and criteria of more general aspects of social functioning. Tapping the issues pointed out above, the authors present an overview of a normatively based social profiling instrument (the BEST-Index), and discuss evidence for its validity, reliability, and aspects of clinical utility.     

Substance use and PTSD symptoms impact the likelihood of rape and revictimization in college women

The present study utilized a mixed retrospective and prospective design with an 8-month follow-up period to test a model of revictimization that included multiple childhood (i.e., child sexual, physical, and emotional abuse) and situational variables (i.e., substance use, sexual behavior) for predicting rape among 276 college women. It was of particular interest to determine whether traumatic responses (e.g., posttraumatic symptomatology or risky behavior) increased vulnerability for revictimization. During the 8-month follow-up period, 9% of participants were raped; 88% of assaults involved substance use by the victim. Posttraumatic stress disorder (PTSD) symptomatology predicted rape, substance use, and sexual behavior. Substance use, but not sexual behavior, mediated the relation between PTSD symptomatology and rape during the follow-up period. Sexual behavior indirectly impacted risk for rape via substance use. Results suggest that college women with PTSD symptomatology may be at greater risk for rape if they use substances to reduce distress.     

Local justice in the allocation of college admissions: A statistical study of beliefs versus practice

This study examines admission decisions at a highly selective private university. A statistical analysis of 300 admission decisions is used to compare admissions officers' beliefs about how the admissions process works with their actual pattern of decisions. As a group, the officers underestimate the effect of applicant race, gender, alumni status, and athletic ability on their academic and personality ratings and final admission decisions. Individual officers place different weights on the decision-making criteria, with the model explaining less variation in the ratings of officers with more years of experience. The comparison of beliefs with practice has implications for evaluating the distributive and procedural fairness of the college admissions process.     

Men and intimate partner rape: characteristics of men who sexually abuse their partner

This article explores men's use of sexual violence against their intimate partner. Although there is a growing body of information about men's use of physical violence, there is less data about men's sexual violence in intimate partnerships. Data were collected from 229 men who were enrolled in an intervention program for men who abuse. Of men in this study, 53% had sexually assaulted their partner at least one time. This article will address the ways in which this sample of men sexually abused their partner and the connection between physical and sexual abuse within their relationships.     

Sexuality, substance use, and susceptibility to victimization: risk for rape and sexual coercion in a prospective study of college women

An 8-month prospective study examined behavioral, personality, and psychological variables thought to increase vulnerability for college women's experience of rape and verbal sexual coercion. Participants were 276 college women who completed self-report surveys. During 1 academic year, 9.5% of women were raped and 11.7% reported verbal sexual coercion. Elevated levels of sexual concerns, dysfunctional sexual behavior, and impaired self-reference were associated with both verbal sexual coercion and rape. Alcohol and marijuana use increased risk only for rape, whereas self-criticism and depression increased risk only for verbal coercion. Findings suggest that multiple aspects of sexuality, such as shame regarding sexuality and using sex to meet nonsexual needs, may increase risk for both types of sexual victimization. Results support conclusions that rape and verbal sexual coercion have both shared and unique risk factors. Implications for future research and intervention programs are discussed.     

Experimental results of fingerprint comparison validity and reliability: A review and critical analysis

Our purpose in this article is to determine whether the results of the published experiments on the accuracy and reliability of fingerprint comparison can be generalized to fingerprint laboratory casework, and/or to document the error rate of the Analysis–Comparison–Evaluation (ACE) method. We review the existing 13 published experiments on fingerprint comparison accuracy and reliability. These studies comprise the entire corpus of experimental research published on the accuracy of fingerprint comparisons since criminal courts first admitted forensic fingerprint evidence about 120 years ago. We start with the two studies by Ulery, Hicklin, Buscaglia and Roberts (2011, 2012), because they are recent, large, designed specifically to provide estimates of the accuracy and reliability of fingerprint comparisons, and to respond to the criticisms cited in the National Academy of Sciences Report (2009).Following the two Ulery et al. studies, we review and evaluate the other eleven experiments, considering problems that are unique to each. We then evaluate the 13 experiments for the problems common to all or most of them, especially with respect to the generalizability of their results to laboratory casework.Overall, we conclude that the experimental designs employed deviated from casework procedures in critical ways that preclude generalization of the results to casework. The experiments asked examiner-subjects to carry out their comparisons using different responses from those employed in casework; the experiments presented the comparisons in formats that differed from casework; the experiments enlisted highly trained examiners as experimental subjects rather than subjects drawn randomly from among all fingerprint examiners; the experiments did not use fingerprint test items known to be comparable in type and especially in difficulty to those encountered in casework; and the experiments did not require examiners to use the ACE method, nor was that method defined, controlled, or tested in these experiments.Until there is significant progress in defining and measuring the difficulty of fingerprint test materials, and until the steps to be followed in the ACE method are defined and measurable, we conclude that new experiments patterned on these existing experiments cannot inform the fingerprint profession or the courts about casework accuracy and errors.     

Regional differences in spanking experiences and attitudes: A comparison of Northeastern and Southern college students

This study examined regional differences in college students experiences with corporal punishment. Students from two universities, one in the Northeast and one in the South, were surveyed about three aspects of spanking: their experiences receiving physical punishment, their assessments of their punishments, and their attitudes toward spanking. In general, Northeastern students were less likely than Southern students to have been hit and were hit less frequently. Further, Northeastern students were less likely than Southern students to feel that their spankings were justified, and less likely to favor spanking. Analyses of covariance for selected dependent variables controlling for religion, parents' education, and gender revealed that the effect of region was more important for attitudes than for behaviors. Implications of the findings for parents, children, and family professionals are discussed.     

The use and acceptance of sexually aggressive tactics in college men

This study extended the findings of Cleveland, Koss, and Lyon's (1999) research on rape tactics to a sample of college men by examining the use and acceptance of sexually aggressive tactics. Participants included 297 male undergraduate students who filled out instruments assessing for a history of sexual aggression and other personality characteristics. In addition, a measure was created to assess acceptance of sexually aggressive tactics, the Sexual Strategies Questionnaire, and a principal components analysis indicated the presence of two components: overt and covert tactics. Although the overt and covert tactics are comparable to those found by Cleveland and colleagues, the former may provide a greater level of discrimination between general and tactical alcohol usage. Finally, a regression analysis demonstrated that a history of sexually aggressive behavior and increased hypergender ideology were found to predict acceptance of sexually aggressive tactics. Directions for future research are discussed.
