Consistency and Accuracy of Batterer Typology Identification

Researchers in the field of domestic violence have derived “typologies” to better conceptualize the differences found among batterers (e.g., Holtzworth-Monroe and Stuart [1994]. Psychol. Bull. 116: 476–497). Efforts have since been made to evaluate clinicians' accuracy in classifying batterers into subtypes (Langhinrichsen-Rohling, Huss, and Ramsey [2000]. J. Fam. Violence 15: 37–53). The present study investigated the accuracy and consistency with which experienced clinicians could sort profiles into an empirically derived MCMI-based batterer typology (Hamberger, Lohr, Bonge, and Tolin [1996] Violence Vict. 11: 277–292). Seven PhD level psychologists with experience in the field of domestic violence were asked to sort 36 MCMI profiles into three piles. Each pile was represented by each of the three prototypical cluster types described in Hamberger et al. (1996) using the Basic 8 MCMI subscales. Overall, expert raters were able to sort most profiles into the three clusters accurately. However, the expert raters had the most difficulty correctly sorting some of the “nonpathological” profiles, as 40% were placed into the antisocial cluster and (6%) were sorted into the negativistic-dependent cluster. There are a number of possible explanations for the lower accuracy in sorting the nonpathological cluster. Results suggest that psychologists with domestic violence training can accurately sort MCMI profiles of batterers into the main three subtypes derived from empirically-based typology research. Clinical implications for typology assessment are discussed.     

Drug and violence prevention: Rediscovering the critical rational dimension of evaluation research

Following criticism of government-funded drug prevention activities of the early 1990s, a spate of best practice or science-based lists of alcohol, drug and violence prevention programs have been produced by federal agencies in recent years. The writings of Donald T. Campbell on validity have had a profound influence on the development of the methodological quality scales that have been utilized in the review processes used to generate these lists. Implicit in this approach to the identification of science-based prevention programs is the idea that science is equivalent to research methodology and study design. Following Karl Popper and Campbell, I contend that, while certain designs are clearly better than others in dealing with threats to internal validity and allow for better generalization of results beyond the study population, utilization of these designs in and of itself is not sufficient to designate an evaluation study as scientific. Nor can the accumulation of data from such studies be used to proclaim an entire area of research a science, as has occurred with the field of so-called prevention science. Rather, the fundamental criterion by which to judge the scientific status of a theory is falsifiability. If the field of drug and violence prevention is truly a science, then it should be subjecting its predictions about the effects of intervention programs to genuinely critical tests and not attempting to verify these hypotheses. It is argued that it has failed to do this, and two specific examples of prevention programs that appear on a number of science-based lists of prevention programs are discussed.     

Racial Solidarity and Political Participation

Studies conducted in the 1960s and 1970s generally confirmed that racial group solidarity boosted rates of participation among African Americans. But since the 1980s, research has tended to conclude that the effect of solidarity on voter turnout among blacks and other minorities has moderated if not faded entirely. We hypothesize that part of this observed decline is explained by a dilution of measures of group solidarity in recent studies. We argue that a fair test of racial solidarity requires using a comprehensive measure that incorporates both psychological “identification” and the ideological beliefs that comprise “consciousness.” Moreover, we hypothesize that the effects of solidarity, will vary across forms of participation and be greatest on political activities that require group coordination. Our re-analysis of the 1984 NBES using separate measures of identification and consciousness indicates that the more narrowly circumscribed measures of these concepts used in recent studies are likely to have underestimated its influence on political participation. We show that racial identification and consciousness had a modest effect on voting turnout in 1984, but a significant influence on participation in several traditional campaign activities, petitioning government officials, and especially participation in protests and boycotts.     

The effects of mass media on crime prevention awareness,attitudes, and behavior: The case of crime stoppers

Research has been limited on the effects of mass media in increasing awareness of and participation in crime prevention programs. Mass media campaigns have been criticized as ineffective because they are neither informative nor motivating. Crime Stoppers is a program that appears responsive to these criticisms. The program involves dramatic reenactment of unsolved crimes and promises monetary rewards and anonymity for persons with information leading to the arrest or conviction of criminals. The present research examines the effects of Crime Stoppers on awareness, attitudes, and behaviors. Implications for theory and policy are discussed.     

Game tree analysis of international crises

Conflicts among nations can often be understood as games in which players (nations) possessing strategies (the sets of actions they may take) face alternative consequences (loss or gain of territory or prestige) determined by their choices of action. Amenable to this type of analysis is the recent Falkland Islands crisis involving Argentina and Great Britain. The events in this case provide an illustration of the way “three-stage, two-person sequential game tree models” can explain the outcome of a crisis situation, whether the parties involved possess perfect information regarding the likely actions of their opponents or are subject to misperceptions about them. When misperceptions occur, the effects can be severely detrimental to both players. Under certain conditions a single misperception by a player of an opponent's preferences can lead to conflict even though both players would have preferred another outcome, one that would in fact have resulted if the error in perception had not occurred. Thus, the outcome of such a “game” is highly sensitive not only to the players' actual preferences but to mutual perceptions of those preferences.     

Social learning and adolescent deviance abstention: Toward understanding the reasons for initiating,quitting, and avoiding drugs

Tests of theories that attempt to explain why individuals currently use drugs are widespread; however, the theoretical examinations of abstention from drugs and the cessation of their use are rare. For its part, social learning theory has been supported consistently in its delineation of the process by which substance use is learned. We propose that cessation and abstention are also learned behavior. Using logistic regression analysis, we examine the ability of social learning variables to distinguish among abstainers, current users, and former users of illicit drugs within a sample of 1688 middle- and high-school students in two widely separated nonurban communities. Results indicate that social learning variables clearly distinguish abstainers from current users but are less able to distinguish former users and current users or former users from abstainers. The theoretical, research, and policy implications of these findings are examined in detail.
