ItemEvaluating the concurrent validity of the HCR-20 scales(2013) Jung, Sandy; Ledi, Denise; Daniels, MelissaThe Historical, Clinical and Risk Management (HCR-20) violence risk assessment scheme was constructed to be applicable to a variety of populations, including civil and forensic psychiatric patients and correctional offenders. Research has demonstrated that the HCR-20 is strongly linked to forensic hospital readmissions and to increased risk for future violence. However, few studies have examined the psychometric properties of the HCR-20; of particular interest, the HCR-20 clinical and risk management (RM) items have had little cross-validation with other measures using independent samples. The present study is an archival examination of offenders who have been assessed at a forensic outpatient clinic and for whom the HCR-20 was used as part of the assessment. Concurrent validity was explored by correlating the Historical, Clinical and RM scales and its items with theoretically relevant constructs as measured by other psychometric measures, including the personality assessment inventory. A series of analyses to investigate the validity of the HCR-20 are reported using a small community forensic sample originally assessed at the presentence stage in the legal process. This research provides a much needed investigation of the concurrent validity for the scales and items of the HCR-20. ItemAn examination of convergent constructs among Level of Service measures and other measures(2012) Jung, Sandy; Daniels, Melissa; Friesen, Michael; Ledi, Denise; Jung, SandyThe Level of Service Inventory-Revised and its successor, the Level of Service/Case Management Inventory are theoretically based risk assessment measures derived from what are known as the “Central Eight” risk factors. These Level of Service instruments have been empirically demonstrated to predict recidivism; however, given the importance of using the these instruments to assess the central eight risk factors, it is also important to ensure that the measures’ subscales are actually assessing the intended constructs. In the present study, files of 219 offenders were coded to investigate the concurrent and discriminant validity by correlating seven of the Level of Service subscales with construct-relevant scales of the Personality Assessment Inventory, Cormier-Lang Criminal History Score, Minnesota Multiphasic Personality Assessment-2, and intelligence measures. The results provide preliminary support for the construct validity of the domains measured by the Level of Service instruments, with the exception of the Emotional/Personal subscale. ItemMissed initial appointments at an outpatient forensic psychiatric clinic(2009) Daniels, Melissa; Jung, SandyNon-attendance at first appointments is a significant problem in both the health and mental health care systems, and much of the research that has aimed to identify possible predictors of initial appointment, non-attendance at general treatment facilities have often provided contradictory and inconclusive results. This retrospective study reviewed the charts of patients who were referred to an outpatient forensic psychiatric clinic over a two-year period and identified a subset of patient- and clinic-related factors that have previously been identified in the literature to be associated with non-attendance. Of the 1630 charts reviewed, only 71.7% of patients attended their initial appointment. The findings indicated that forensic patients who were older and faced consequences related to sentencing were most likely to attend their initial appointments. The potential to improve attendance and subsequent treatment by identifying common factors that contribute to missing initial appointments is discussed, along with implications for increased efficiency of service delivery.
