Using dynamic risk and protective factors to predict inpatient aggression: Reliability and validity of START assessments

The Short-Term Assessment of Risk and Treatability (START; C. D. Webster, M. L. Martin, J. Brink, T. L. Nicholls, & S. L. Desmarais, 2009; C. D. Webster, M. L. Martin, J. Brink, T. L. Nicholls, & C. Middleton, 2004) is a relatively new structured professional judgment guide for the assessment and management of short-term risks associated with mental, substance use, and personality disorders. The scheme may be distinguished from other violence risk assessment instruments because of its inclusion of 20 dynamic factors that are rated in terms of both vulnerability and strength. This study examined the reliability and validity of START assessments in predicting inpatient aggression. Research assistants completed START assessments for 120 male forensic psychiatric patients through review of hospital files. They also completed Historical-Clinical-Risk Management-20 (HCR-20; C. D. Webster, K. S. Douglas, D. Eaves, & S. D. Hart, 1997) and Hare Psychopathy Checklist: Screening Version (PCL:SV; S. D. Hart, D. N. Cox, & R. D. Hare, 1995) assessments. Outcome data were coded from hospital files for a 12-month follow-up period using the Overt Aggression Scale (OAS; S. C. Yudofsky, J. M. Silver, W. Jackson, J. Endicott, & D. W. Williams, 1986). START assessments evidenced excellent interrater reliability and demonstrated both predictive and incremental validity over the HCR-20 Historical subscale scores and PCL:SV total scores. Overall, results support the reliability and validity of START assessments and use of the structured professional judgment approach more broadly, as well as the value of using dynamic risk and protective factors to assess violence risk.

Culture,Institutions, and Morally Dubious Behaviors: Testing Some Core Propositions of the Institutional-Anomie Theory

This study draws on self-report data on the prevalence of morally dubious behaviors in Europe to examine Messner and Rosenfeld's institutional-anomie theory. Institutional-anomie theory tries to explain cross-national differences in crime rates through the interplay between the cultural commitments and the institutional arrangements characterizing a society. The relevant state of research is unsatisfactory and full of gaps. Deficiencies exist, especially with regard to the postulated cultural dynamics. Findings from a series of multilevel models testing the combined effects of cultural forces and social institutions on respondents’ engagements in morally dubious behaviors that are committed in pursuit of self-interest—thereby controlling for differences in sociodemographic composition—shed doubt on the theory's explanatory power. Neither the cultural imperatives of the “American Dream” nor the extent of anomic orientations are linked in the expected manner to the observed cross-national variation in rates of moral misconduct across Europe.     

Neuro-feedback intervention efficacy for treating children with Autism Spectrum Disorder

This study explored practitioners perceptions of a neuro-feedback intervention in treating children with Autism Spectrum Disorder’s (ASD). Informants were a convenience sample of ten South African neuro-feedback practitioners registered with the Health Professions Council of South Africa (HPCSA). The data on their views on neuro-feedback treatment efficacy, with children with ASD, were collected by means of semi-structured in-depth interviews. Thematic analysis of the data suggest practitioners to perceive neuro-feedback treatment to enhance the social, mood, behaviour, academic life, and family functioning of children with ASD. Additionally, the practitioners perceived neuro-feedback treatment to assist in reducing anxiety among children with ASD.     

Quantum Cooperation

In a theoretical simulation the cooperation of two insects is investigated who share a large number of maximally entangled EPR-pairs to correlate their probabilistic actions. Specifically, two distant butterflies must find each other. Each butterfly moves in a chaotic form of short flights, guided only by the weak scent emanating from the other butterfly. The flight directions result from classical random choices. Each such decision of an individual is followed by a read-out of an internal quantum measurement on a spin, the result of which decides whether the individual shall do a short flight or wait. These assumptions reflect the scarce environmental information and the small brains’ limited computational capacity. The quantum model is contrasted to two other cases: In the classical case the coherence between the spin pairs gets lost and the two butterflies act independently. In the super classical case the two butterflies read off their decisions of whether to fly or to wait from the same internal list so that they always take the same decision as if they were super correlated. The numerical simulation reveals that the quantum entangled butterflies find each other with a much shorter total flight path than in both classical models.     

Comparing the EthoVision 2.3 system and a new computerized multitracking prototype system to measure the swimming behavior in fry fish

Coming from the framework of unmarked fry tracking, we compared the capacities, advantages, and disadvantages of two recent video tracking systems: EthoVision 2.3 and a new prototype of multitracking. The EthoVision system has proved to be impressive for tracking a fry using the detection by gray scaling. Detection by subtraction has given less accurate results. Our video multitracking system is able to detect and track more than 100 unmarked fish by gray scaling technique. It permits an analysis at the group level as well as at the individual level. The multitracking program is able to attribute a number to each fish and to follow each one for the whole duration of the track. Our system permits the analysis of the movement of each individual, even if the trajectories of two fish cross each other. This is possible thanks to the theoretical estimation of the trajectory of each fish, which can be compared with the real trajectory (analysis with feedback). However, the period of the track is limited for our system (about 1 min), whereas EthoVision is able to track for numerous hours. In spite of these limitations, these two systems allow an almost continuous automatic sampling of the movement behaviors during the track.     

The level of effort required for behaviour as a moderator of the attitude–behaviour relation

It was hypothesized that the manner in which attitudes influence behaviour is moderated by the level of effort required to perform a behaviour. The effort needed was manipulated in a field experiment by varying the difficulty of getting access to the attitude object. When the behaviour required substantial effort, the mediating role of intentions was strong, and attitudes had only indirect effects on behaviour, consistent with the theory of reasoned action. When the behaviour required little effort, however, attitudes had a significant direct effect on behaviour, and the mediating role of intentions was reduced. The theoretical and practical implications of these findings are discussed.     

Der Foto-Hand-Test

Projective psychological techniques might be useful for measuring forensically relevant constructs in the context of a multimodal assessment strategy but are often considered to be deficient concerning reliability and validity. The Photo Hand Test (FHT), a German version of the Hand Test, is a diagnostic tool aimed at measuring aggressive dispositions. It uses photographs of hand gestures which test persons are required to interpret. The answers are coded and an acting-out score is computed from diverse categories.A study on the reliability and validity of the FHT protocols from 98 offenders and a comparison group of 55 non-offenders was carried out. Internal consistency coefficients of the FHT scores were low and unsatisfactory. Offenders had higher acting-out scores than non-offenders, they did not give more aggression-prone interpretations but more interpretations coded as aggression-inhibiting. Correlations of the FHT scores with self-report scales from the Antisocial Personality Questionnaire did not show the expected patterns; however, they did suggest effects of a hostility bias: persons who interpreted many hand gestures as aggression-prone did not describe themselves as highly aggressive or impulsive but were more distrustful and paranoid. This indicates a projection mechanism different from the one postulated by the FHT authors.The results suggest that FHT measures should be interpreted with caution in forensic evaluations.     

„Intention to treat“ oder „treatment as received“ – Umgang mit Abbrechern in der Forschung zur Straftäterbehandlung

Lack of internal validity is a frequent problem in evaluation studies of offender treatment, as randomized controlled trials are difficult to implement and comparison groups in quasi-experimental studies are often not completely equivalent. Special matching procedures or statistical control of selection bias by using potentially interfering variables as covariates can provide a solution to some of these problems; however, a high dropout rate from offender treatment programs presents another problem, as the variables that cause attrition are often risk factors for reoffending. It is argued that a treatment-as-received (TR) approach which compares treatment completers with the comparison group may confound genuine treatment effects with selection effects. Particularly high recidivism rates in dropouts may be due to negative effects of attrition (e.g. stigmatization) but may more likely reflect a higher a priori risk for reoffending. Using data from some recent treatment studies, the authors show that alleged positive effects often disappear when a more adequate intention-to-treat (ITT) approach is used in which dropouts are retained in the treatment sample.
