Behavioural treatment of obsessional-compulsive patients in routine clinical practice

There is a paucity of information available about the extent to which findings from research studies of behavioural treatments can be generalised to routine clinical practice. The characteristics and treatment at a series of 36 patients with obsessional-compulsive disorders who were referred to a National Health Service Behaviour Therapy Clinic are described. It appears that the methods developed and evaluated in research trials have been incorporated into everyday clinical practice, with some modifications (e.g. less in vivo practice but more home task assignment). The outcomes reported in the research trials were replicated in the clinical setting, and were shown to be achieved economically in terms of therapist time.     

On the numerical approximation of the bivariate normal (tetrachoric) correlation coefficient

In this paper a rapid and reliable method is found for estimating the value of the Bivariate Normal Correlation Coefficient, ρ, given values of the joint probability and the normal deviates,h andk, or the related areas. This technique finds useful application in the computational approximation of the tetrachoric correlation coefficient,r, when the underlying distributions may be assumed to be normal.     

Zum Zusammenhang zwischen Projektionsoperatoren und Eigenschaften

Der nichtdistributive, orthokomplementäre Verband der Projektionsoperatoren in der Quantenmechanik hat Anlaß zu mancherlei Interpretationen gegeben, so z. B. als eine von der klassischen Logik abweichende Quantenlogik, oder man deutete die Projektionsoperatoren als Eigenschaften von Mikroobjekten. Wir glauben, mit dieser Arbeit ein wesentliches Argument für die letztere Interpretation liefern zu können:Es ist nämlich möglich, in der Menge der Eigenschaftsbegriffe eine Ordnungs-relation einzuführen. Mit dieser Ordnungsrelation bildet einen nichtdistributiven, orthokomplementären Verband. D.h. bei einer solchen Interpretation werden keinerlei Veränderungen — weder im Verband der Aussagen noch im Verband der Eigenschaftsbegriffe — durch die Entdeckung der Quantenmechanik notwendig.     

A comparison of two psychological treatments for bulimia nervosa

Two standardized psychological treatments for bulimia nervosa were studied. A cognitive behavioural approach was compared with a form of short-term focal psychotherapy. Twenty-four patients who met strict diagnostic criteria for bulimia nervosa were randomly allocated to the two treatments. All the interviews were tape-recorded so that checks on their content could be made. Assessments took place at the beginning and end of treatment, and at 4-, 8- and 12-month follow-up. None of the patients dropped out of treatment or follow-up, but 1 patient from each treatment group had to be withdrawn on clinical grounds. Patients in both groups made substantial improvements which were well maintained over the 12-month treatment-free follow-up period. The cognitive behavioural approach was superior to short-term focal psychotherapy in terms of its effect on the patients' overall clinical state, their general psychopathology and social adjustment, and their assessment of their outcome.     

Affect intensity and the appraisal of emotion

The present study investigated the association between a personality trait known as affect intensity and the perceived qualities of emotions. Subjects completed the Affect Intensity Measure (AIM), and they rated the phenomenological qualities and causal dimensions of previous emotional experiences involving happiness, pride, anxiety, and hate. The results showed that high and low scorers on the AIM reported different perceptions of certain qualities of the emotional event, independent of the emotion's valence; subjects with high scores on the AIM rated their emotions as higher in intensity, frequency, and vividness of recall. In contrast, further analyses revealed little relation between AIM scores and causal dimension ratings of the emotions. However, within-subject analyses indicated that the emotions did differ in their perceived causes, thus supporting predictions from Weiner's attributional model of emotion. The results are discussed in terms of the need for a complex approach to the study of emotion which incorporates intersubject and intrasubject differences.     

An empirical investigation of psychopathy in a noninstitutionalized and noncriminal sample

This study examined the construct of psychopathy using the Psychopathy Checklist-Revised (PCL-R) in 54 participants from the general population. To obtain a sample of community participants with psychopathic characteristics, participants were recruited using advertisements for a "personality study" that incorporated the characteristics of psychopathy in a nonpejorative manner. The methodology successfully recruited community participants with moderately elevated PCL-R scores. Participants exhibited the personality features of psychopathy (Factor 1) to a greater extent than the behavioral features (Factor 2), which is consistent with the results obtained with the PCL-R normative samples. Roughly 40% of the sample reported no history of involvement with the criminal justice system, yet these participants exhibited moderately elevated PCL-R scores. Moreover, a sizeable portion of the noncriminal participants reported a substantial history of violent behavior. Comparisons of PCL-R scores between participants with and without a criminal history suggest that these two groups differ in ways unrelated to criminal justice system involvement.
