This study examined the reliability and validity of Short-Term Assessment of Risk and Treatability (START) and Level of Service Inventory–Revised (LSI-R) assessments overall and by client race. Research assistants completed START and LSI-R assessments for 95 diversion clients. Arrests and jail days were collected via official records and self-report 3, 6, 9, 12, and 18 months after baseline. Assessments demonstrated good interrater reliability and convergent validity. START strength total scores and LSI-R risk estimates were the strongest predictors of recidivism. Total scores and risk estimates did not differ as a function of client race, but there were some differences in accuracy of START vulnerability and LSI-R total scores and risk estimates in predicting jail days (but not arrests), over shorter follow-ups. No such differences were found for START strength total scores across any follow-up period or recidivism measure. }, number={7}, journal={ASSESSMENT}, author={Lowder, Evan M. and Desmarais, Sarah L. and Rade, Candalyn B. and Johnson, Kiersten L. and Van Dorn, Richard A.}, year={2019}, month={Oct}, pages={1347–1361} }

However, little is known regarding correlates of such behaviors within this population. In a community-based sample of women who use methamphetamine ( N = 322), we examined participant characteristics (i.e., demographics, drug- and sex-related behaviors, and mental health characteristics) associated with three operationalizations of risky heterosexual behaviors in the past 6 months (i.e., number of male partners, condomless sex with male partners, and both multiple male partners and condomless sex). Analyses revealed important distinctions in the correlates of risky heterosexual behaviors as a function of outcome. Results suggest that HIV and STI prevention strategies should consider characteristics associated with differing risky heterosexual behaviors. In addition, differences in correlates of these behaviors suggest a need for standardization in measurement and evaluation of sexual risk in research and practice with women who use methamphetamine. }, number={2}, journal={Journal of Drug Issues}, publisher={SAGE Publications}, author={Johnson, Kiersten L. and Desmarais, Sarah L. and Van Dorn, Richard A. and Lutnick, Alexandra and Kral, Alex H. and Lorvick, Jennifer}, year={2016}, month={Feb}, pages={148–160} }

This study examined the role of static indicators and proximal, clinically relevant indicators in the prediction of short-term community violence in a large, heterogeneous sample of adults with mental illnesses.


METHODS
Data were pooled from five studies of adults with mental illnesses (N=4,484). Follow-up data were available for 2,579 participants. A hierarchical linear regression assessed the incremental validity of a series of variable clusters in the prediction of violence risk at six months: static characteristics (age, sex, race-ethnicity, and primary diagnosis), substance use (alcohol use and drug use at baseline), clinical functioning (psychiatric symptoms at baseline and recent hospitalization), recent violence, and recent victimization.


RESULTS
Results demonstrated improved prediction with each step of the model, indicating that proximal indicators contributed to the prediction of short-term community violence above and beyond static characteristics. When all variables were entered, current alcohol use, recent violence, and recent victimization were positive predictors of subsequent violence, even after the analysis controlled for participant characteristics.


CONCLUSIONS
This study provides empirical evidence for three proximal, clinically relevant indicators in the assessment and management of short-term violence risk among adults with mental illnesses: current alcohol use, recent violence, and recent victimization. Consideration of these indicators in clinical practice may assist in the identification of adults with mental illnesses who are at heightened risk of short-term community violence.}, number={7}, journal={Psychiatric Services}, publisher={American Psychiatric Association Publishing}, author={Johnson, Kiersten L. and Desmarais, Sarah L. and Grimm, Kevin J. and Tueller, Stephen J. and Swartz, Marvin S. and Van Dorn, Richard A.}, year={2016}, month={Jul}, pages={771–778} }

We also explored participant characteristics differentiating four categories of perpetration and victimization: non-victim/non-perpetrators, victims only, perpetrators only, and victim–perpetrators. Results indicated that adults with mental illnesses were unlikely to report violent outcomes but, when they did, were more likely to report perpetration and victimization, rather than perpetration alone. In addition, bivariate and multivariable analyses showed that sex, age, race/ethnicity, and primary diagnosis differed across categories. Victim–perpetrators, for example, were more likely to be young, Black, and have a primary diagnosis of bipolar disorder, major depressive disorder, substance use disorder, or “other.” Altogether, our findings provide evidence for a victim–perpetrator overlap in this population and suggest that preventive measures targeting violence and victimization may be more effective than those with separate strategies for each. }, number={3}, journal={Journal of Interpersonal Violence}, publisher={SAGE Publications}, author={Johnson, Kiersten L. and Desmarais, Sarah L. and Van Dorn, Richard A. and Grimm, Kevin J.}, year={2014}, month={Jun}, pages={522–540} }

This study sought to (a) examine perceptions of police held by PMI, (b) compare them to perceptions held by the general population, and (c) explore whether differences between PMI and general population perceptions are attributable to contact with the police in the past year. We drew data from a survey of 244 PMI and the 2009 Canadian General Social Survey (GSS) (Brennan, 2011). Both surveys administered the same items querying perceptions of and contact with the police in the prior 12 months. GSS participants were individually matched to PMI participants on sociodemographic characteristics (n = 225 per group). Overall, participants held fairly positive perceptions of the police, but perceptions held by GSS participants were more positive than those held by PMI participants. PMI participants were more likely than GSS participants to have contact with the police in the prior 12 months. In multivariate models, perceptions differed between PMI and GSS participants for police performance in being approachable and treating people fairly, and overall confidence in police; police contact was not associated with perceptions nor did it moderate effects of participant group. Consistent with the procedural justice framework, fair and equitable treatment appears to be of primary relevance to PMI perceptions of the police.
