Shared decision making (SDM) is being increasingly challenged for promoting an innovative role model while adhering to an archaic approach to patient‐clinician communication, both in clinical practice and the research field. Too often, SDM has been studied at the individual level, which ignores the interpersonal system between patients and physicians. We aimed to encourage debate by reflecting on the essentials of SDM in terms of epistemology. We operationalized the SDM core concept of information exchange in terms of social systems theory. An epistemological analysis of the term information refers to its inherent process character. Exchange of information thereby becomes synonymous with social sense construction, indicating that, rather than just being a vehicle, the act of communication itself is the information. We plead for the adoption of existing dyadic analytical methods such as those offered by the interpersonal paradigm. Implications of an updated concept of information for the use of SDM‐evaluation methods, for SDM‐goal setting, and for clinical practice of SDM are described.

Background The wide scale permeation of health care by the shared decision making concept (SDM) reflects its relevance and advanced stage of development. An increasing number of studies evaluating the efficacy of SDM use instruments based on various sub-constructs administered from different viewpoints. However, as the concept has never been captured in operable core definition it is quite difficult to link these parts of evidence. This study aims at investigating interrelations of SDM indicators administered from different perspectives. Method A comprehensive inventory was developed mapping judgements from different perspectives (observer, doctor, patient) and constructs (behavior, perception) referring to three units (doctor, patient, doctor-patient-dyad) and an identical set of SDM-indicators. The inventory adopted the existing approaches, but added additional observer foci (patient and doctor-patient-dyad) and relevant indicators hitherto neglected by existing instruments. The complete inventory comprising a doctor-patient-questionnaire and an observer-instrument was applied to 40 decision consultations from 10 physicians from different medical fields. Convergent validities were calculated on the basis of Pearson correlation coefficients. Results Reliabilities for all scales were high to excellent. No correlations were found between observer and patients or physicians neither for means nor for single items. Judgements of doctors and patients were moderately related. Correlations between the observer scales and within the subjective perspectives were high. Inter-perspective agreement was not related to SDM performance or patient activity. Conclusion The study demonstrates the contribution to involvement made by each of the relevant perspectives and emphasizes the need for an inter-subjective approach regarding SDM measurement.

The current study examined the relationship between psychopathy, intelligence and two variables describing the conviction history (length of conviction and number of prior convictions). It was hypothesized that psychopathy factors (interpersonal and antisocial factors assuming a 2-factor model or interpersonal, affective, lifestyle and antisocial factors assuming a 4-factor model) would be related in different ways to IQ scores, length of conviction and number of prior convictions. Psychopathy and IQ were assessed using the PCL:SV and the CFT 20-R respectively. Results indicated no association between interpersonal psychopathy features (Factor 1, two-factor model), IQ and the number of prior convictions but a positive association between Factor 1 and the length of conviction. Antisocial features (Factor 2, two-factor model) were negatively related to IQ and the length of conviction and positively related to the number of prior convictions. Results were further differentiated for the four-factor model of psychopathy. The relationship between IQ and psychopathy features was further assessed by statistically isolating the effects of the two factors of psychopathy. It was found that individuals scoring high on interpersonal features of psychopathy are more intelligent than those scoring high on antisocial features, but less intelligent than those scoring low on both psychopathy features. The results underpin the importance of allocating psychopathic individuals to subgroups on the basis of personality characteristics and criminological features. These subgroups may identify different types of offenders and may be highly valuable for defining treatment needs and risk of future violence.

OBJECTIVE Shared decision making (SDM) between patient and physician is an interpersonal process. Most SDM measures use the view of one party (patient, physician or observer) as a proxy to capture this process although these views typically diverge. This study suggests the compound measure SDM(MASS) (SDM Meeting its concepts ASSumptions) integrating these three perspectives in one single index. METHODS SDM(MASS) was derived theoretically and compared empirically to unilateral perspectives of patients, physicians and observers by application to a data set of 10 physicians (40 consultations) receiving an SDM training. RESULTS The constituting parts of SDM(MASS) were highly reliable (Cronbachs alpha .94; interrater reliability .74-.87). Unilateral appraisal of training effects was divergent. SDM(MASS) revealed no effect. CONCLUSION SDM(MASS) combines noteworthy information about SDM processes from different viewpoints and thereby delivers plausible assessments. It could overcome immanent shortcomings of unilateral approaches. However, it is a complex measure needing further validation.

We investigated possible age differences in the frequency of antisocial personality disorder (ASPD), and of psychopathy according to Hares criteria and its constituent features: In a cross-sectional study 226 male violent offenders, detained in adult or youth custody, were investigated using the Psychopathy Checklist Screening Version (PCL:SV) and the SCID II Interview. Their ages ranged from 18 to 59 years. Total PCL:SV score was negatively correlated with age. ANOVA showed that total PCL scores for three age groups differed significantly. Both effects were due entirely to Factor 2 of the PCL. Factor 1 was not related to age. The frequency of ASPD was also lower among older prisoners. The relationship with age was similar to that of PCL:SV Factor 2. These results point to age-related effects in psychopathy and suggest that different aspects of psychopathy follow different developmental courses. The results of our group comparison suggest that the different subfacets of psychopathy are not stable over time to the same extent. In order to make statements about the course of intraindividual development, however, longitudinal studies would be required.

Objective: This study examined the predictive validity of the German translation of the Psychopathy Checklist-Screening Version (PCL-SV) for negative events during the course of the prison sentence of German prisoners. Method: Using the PCL-SV, we investigated 145 offenders in a German prison at the start of their sentences. We then compared the extreme groups identified by the PCL-SV—the high and low scorers—using a prospective design with respect to negative events and factors during the course of the sentences. This involved the standardized collection of data on both objective records of disciplinary incidents and subjective impressions from prison staff on the basis of operationalized criteria. Results: The high scorers were involved in significantly more disciplinary incidents and were also rated significantly less favourably by prison staff than the low scorers. Conclusion: Until now, the PCL has only been shown to predict recidivism following release from prison. The results of our study show that the PCL also has predictive validity for problems during the course of the sentence. It is therefore recommended that the PCL be used routinely at the start of the prison sentence to estimate the likelihood of subsequent difficulties.

BackgroundEmesis and nausea are side effects induced by chemotherapy. These effects lead to enormous stress and strain on cancer patients. Further consequences may include restrictions in quality of life, cachexia or therapy avoidance. Evidence suggests that cancer patients develop the side effects of nausea and vomiting in anticipation of chemotherapy. Contextual cues such as smell, sounds or even the sight of the clinic may evoke anticipatory nausea and vomiting prior to infusion. Anticipatory nausea and vomiting are problems that cannot be solved by administration of antiemetica alone.The purpose of the proposed randomized placebo-controlled trial is to use an overshadowing technique to prevent anticipatory nausea and vomiting and to decrease the intensity and duration of post-treatment nausea and vomiting. Furthermore, the effect on anxiety, adherence and quality of life will be evaluated.Methods/DesignFifty-two pediatric cancer patients will be evenly assigned to two groups: an experimental group and a control group. The participants, hospital staff and data analysts will be kept blinded towards group allocation. The experimental group will receive during three chemotherapy cycles a salient piece of candy prior to every infusion, whereas the control group will receive flavorless placebo tablets.DiscussionIf an effectiveness of the overshadowing technique is proven, implementation of this treatment into the hospitals’ daily routine will follow. The use of this efficient and economic procedure should aid a reduced need for antiemetics.Trial registrationCurrent Controlled Trials ISRCTN30242271/

Objective: To consider the extent to which the presence of psychopathy, as indicated by the psychopathy checklist: screening version (PCL:SV), can predict intramural behaviour in offenders with mental disorders serving compulsory treatment at a German forensic psychiatric hospital. Method: The PCL:SV was used with 48 offenders detained at a forensic psychiatric hospital in Germany. In a prospective design, objective and subjective measures of behaviour were compared for those identified as high and low scorers on the PCL:SV. Data were obtained from hospital records of disciplinary incidents (objective) and from interviews with case managers and therapists (subjective), according to predefined criteria and in standardized forms. Results: The hospital records of the high scorers indicated they had been involved in significantly more disciplinary incidents than low scorers. Their behaviour was also rated significantly more negative by therapists than the low scorers. Conclusion: Numeorus studies found the psychopathy checklist (PCL) score to be a reliable predictor of recidivism in offenders after release. The present study has demonstrated that the PCL score has also predictive validity for intramural behaviour problems in individuals serving compulsory treatment at a forensic psychiatric hospital. As a result, we recommend the routine use of the PCL with offenders starting a period of compulsory detention to identify those at increased risk for problem behaviour.

Shared decision-making (SDM) has the potential to overcome outdated social role models in the health care system. The concept, however, adheres to archaic epistemological assumptions as can be inferred from the rudimentary stage of the measurement methods used and from the information monopoly that the physician still holds in this concept. Advantages of an up-to-date model of knowledge for understanding and operationalising SDM are outlined. To this purpose, essential definitions of the concept are reflected in terms of epistemology. Accordingly, information emerges through a process of social construction. Likewise, interpersonal relations do not represent a static condition; rather, they develop anew with each interaction. Therefore, constructs suitable to focus on dyadic interaction processes can be used as indicators of sharing in SDM. Theories and methods of the interpersonal paradigm are advocated.
