Electrodermal lability in anxiety disorders

Twenty-eight anxiety patients, aged below 50 years, were diagnosed according to DSM-III-R criteria (panic disorder with and without agoraphobia, generalised anxiety disorder, and anxiety disorder not otherwise specified). The patients were characterised by high levels of state and trait anxiety and neuroticism, compared with the controls. However, there were no differences between patients and controls in electrodermal habituation rate, non-specific activity, or skin resistance level. When the patients were divided into electrodermally labile and stable subjects, significant differences were found between patients and controls in both electrodermal activity and Eysenck's personality dimensions. The labile patients were more introverted and attained higher psychoticism scores than either the stable patients or controls. Duration of anxiety symptoms removed the difference found in extroversion, but not in any other variable. The results are discussed in relation to the utility of electrodermal measurements in validation of diagnostic entities. It is concluded, that from the psychophysiological point of view, anxiety disorders may be examined within a dimensional framework.     

Amnesic effects of diazepam: "Drug dependence" explained by state-dependent learning

An experimental study on 12 healthy volunteers showed that an amnesic effect of a therapeutic dose of diazepam (10 mg 3 times a day) may be explained by a theory of state-dependent learning. Asymmetric state-dependence was demonstrated by visually as well as verbally learned material, but in the latter case there was also evidence of an anticonsolidating effect upon learning. The findings are related to drug dependence, and it is suggested that therapeutic gains obtained during long-term diazepam treatment may not transfer to the no-drug state.     

THE NEW UNIFORM GUIDELINES ON EMPLOYEE SELECTION PROCEDURES IN THE CONTEXT OF UNIVERSITY PERSONNEL DECISIONS

The new Uniform Guidelines on Employee Selection Procedures are considered in a context of university employment decisions. The use of student evaluations as valid criteria for faculty personnel decisions such as hiring, retention, tenure, promotion, or salary increases is examined. Standards of validity contained in the Guidelines are probably not being met with regard to most student rating forms currently used. Recommendations are made regarding use of student and administrators' ratings as criteria for personnel decisions. The need for studies on contaminating sources of variance in ratings is emphasized.     

The Epidemiology of Homicide followed by Suicide: A Systematic and Quantitative Review

This systematic review of population based studies of homicide followed by suicide was conducted to examine the associations between rates of homicide‐suicide, rates of other homicides and rates of suicide. The review analysed 64 samples, including the case of an outlier (Greenland) that were reported in 49 studies. There was a significant association between the rates of homicide‐suicide and those of other homicides in studies from the U.S.A. Outside the U.S.A. there was no clear association between homicide‐suicide and other homicide but there was modest but significant association between rates of suicide and homicide‐suicide. Homicide‐suicide appears to be closer in epidemiological terms to homicide than suicide in regions with high rates of homicide and measures to reduce homicide in these regions may also reduce homicide‐suicide.
