Improving forensic tribunal decisions: the role of the clinician

Three empirical investigations of forensic decision-making were conducted: a study of 104 hearings by a forensic tribunal; an evaluation of which aspects of forensic patients' clinical presentation were empirical predictors of violence; and a survey of forensic clinicians to determine which factors they said they used to assess risk of violent recidivism and which they actually used. Results showed a significant correlation between actuarial risk and clinical advice to the tribunal, and a nonsignificant trend for patients higher in actuarial risk to receive more restrictive dispositions. Psychotic diagnoses and symptoms were not indicators of increased risk of violent recidivism. Clinicians endorsed some empirically valid indicators of risk, but also relied on some invalid indicators. There was also inconsistency between factors clinicians said they used and factors actually related to their hypothetical decision-making. An automated system is presented as an illustration of how the consistency and validity of forensic decisions could be enhanced.     

Projection of the Magnocellular Red Nucleus to the Region of the Accessory Abducens Nucleus in the Rabbit

The projection of the magnocellular red nucleus (RNm) to the region of the accessory abducens nucleus (AABD) was traced in rabbit using the bidirectional tracer wheat germ agglutinin-horseradish peroxidase (WGA-HRP). In one set of animals, recordings of antidromic responses from RNm neurons elicited by electrical stimulation of the rubrospinal tract were used to localize injections of WGA-HRP for orthograde labeling of RNm terminals. In a different set of animals, horseradish peroxidase was injected into the retractor bulbi muscle to retrogradely label motoneurons of the AABD. The positions of RNm fibers and terminals were examined and compared to the locations and distribution of AABD cell bodies and labeled dendrites. Analyses revealed that along the entire rostrocaudal extent of the AABD, RNm efferents terminate primarily lateral to, or in the lateral aspects of, labeled motoneurons. For the rostral AABD, RNm efferents terminate only lateral to the nucleus. Although the terminals are not positioned to contact cell bodies of the AABD, they could overlap with dendrites that extend in the lateral direction. RNm efferents terminate more extensively within the posterior AABD, overlapping within both dendritic and cell body regions of the nucleus. Even in this posterior region, however, RNm efferents were distributed primarily over the lateral half of the nucleus. These data show that RNm can monosynaptically influence the AABD, through primarily its lateral and posterior aspects. Our findings also show that a major target of RNm efferents is the reticular cell population located lateral to the AABD, suggesting that the RNm also may affect AABD motoneuronal output indirectly through its projection to reticular cells.

Perfectionism,Shame, and Depressive Symptoms

The authors examined the relationship between depression, maladaptive perfectionism, and shame. Regression analyses were used to replicate a model in which maladaptive perfectionism was negatively associated with self‐esteem and positively associated with symptoms of depression, with self‐esteem mediating the effects of maladaptive perfectionism on depressive symptoms. Additional models showed that the path from maladaptive perfectionism to depression was partially mediated by shame, although these paths differed for men and women.     

Perfectionism and Obsessive-Compulsive Symptoms

This study was designed to determine whether perfectionism, as assessed by the revised almost perfect scale (APS-R; R. B. Slaney, M. Mobley, J. Trippi, J. S. Ashby, & D. G. Johnson, 1996), was a significant predictor of obsessive-compulsive (OC) symptoms in a non-clinical sample of 308 university students. Perfectionistic discrepancy emerged as a general predictor of obsessive thought difficulties and compulsive checking behavior. Excessive concerns about making mistakes also emerged as a significant specific predictor of obsessive cognitive but not behavioral symptoms after other dimensions of perfectionism were controlled. An interaction effect indicated that students with high discrepancy but low standards were more likely to experience OC-related washing symptoms than other students. The general effects of perfectionism on OC symptoms, the specific effects of certain perfectionism dimensions over others, and other perfectionism research results, implicate APS-R discrepancy as a core dimension of maladaptive perfectionism and APS-R high standards as either benign or protective in the associations with OC symptoms.
