Psychometric properties of the Danish MCMI-I translation.

A translation of the MCMI-I has been in use in Denmark for some years. An untested assumption in the interpretation of the pattern of test results is that the psychometric characteristics of the Danish and American versions are similar. The purpose of this study was to evaluate the psychometric properties of the questionnaire by using traditional psychometric analysis techniques on the results of a sample consisting of 423 patients and 179 normal controls. Coefficient alpha was calculated for the 20 clinical subscales of the test and the Danish results were strikingly similar to the original coefficients reported by Millon. Furthermore, factor analysis of the subscales showed a factor structure very similar to American findings, and it is concluded that the psychometric properties of the Danish MCMI are not significantly different from the original.

"Chronic painter's syndrome". A reanalysis of psychological test data in a group of diagnosed cases, based on comparisons with matched controls.

Twenty solvent-exposed workers, most of them painters, had been diagnosed as cases of toxic encephalopathy in 1978/79. Two years later they were re-examined with an extensive battery of neuropsychological tests. Their performance was unchanged on retesting. We have now compared their test results with those of non-exposed control subjects. Previous impressions of significant intellectual impairment in the solvent-exposed patients could not be confirmed when the influence of age, education, and intelligence was taken into consideration. The present group with presumed toxic encephalopathy is assumed to be representative of other patients who were similarly diagnosed in our department. The presently reanalyzed cases had been diagnosed as brain damaged and reported as such in the literature. Thus, they may have contributed to the formation of the concept of the "chronic painters' syndrome" with dementia.

Conservatively treated patients with cerebral arteriovenous malformation: mental and physical outcome.

Twenty five patients with conservatively treated cerebral arteriovenous malformation were followed up for a mean of 10.6 years after diagnosis. The follow up included neuropsychological examination. Bleeding did not occur after the time of diagnosis. Three patients had moderate to severe neurological deficits, five had moderate to severe intellectual impairment. Nineteen had an unaffected occupational status. It is concluded that the outcome in conservatively treated patients may be no worse than in surgically treated patients.

Discrimination between organic and hepatic encephalopathy by means of continuous reaction times.

Measurement of continuous reaction times (CRT) was applied to 105 hospitalized controls, 65 patients with brain damage and 47 patients with hepatic encephalopathy. One hundred and fifty reaction times were measured in every patient. The best discrimination between controls and patients with organic brain damage was obtained with the 10 percentile of the reaction time distribution (86% correct classification). The 90 percentile discriminated best between controls and patients with hepatic encephalopathy (86% correct classification). Furthermore, the ratio between the 50 percentile and the difference between the 10 and 90 percentile made it possible to discriminate between the two groups of patients (91% correct classification), which indicates that the CRT test is suitable as a screening device for discrimination between organic brain damage and hepatic encephalopathy.

Number connection test and continuous reaction times in assessment of organic and metabolic encephalopathy: a comparative study.

Number Connection Test (NCT) and Continuous Reaction Times (CRT) have been used for assessment of encephalopathy in groups of 105 controls, 65 brain damaged patients and 22 patients with hepatic encephalopathy. With the use of NCT, 65% of the patients with cerebral damage could be correctly classified with regard to presence versus absence of brain disease, whereas the use of CRT gave 85% correct classification. With regard to hepatic encephalopathy the CRT was better for classification than NCT; respectively 86% and 64% were correctly classified. The NCT could not separate the patient with brain damage from the patients with hepatic encephalopathy, whereas CRT could classify respectively 95% and 86% correctly. When the tests were performed on five successive days, the NCT scores showed a learning effect, whereas the CRT gave stable measures. This means that the CRT was superior to the NCT for classification purposes.

Intravenous radionuclide angioscintigraphy and computer tomography in cerebral arteriovenous malformations.

In 25 patients with cerebral arteriovenous malformation (AVM) computer tomography (CT) was compared with dynamic and static intravenous radionuclide angioscintigraphy (99mTc-labelled red blood cells). The diagnosis was verified by arteriography performed 2-20 years prior to this study. Scintigrams and CT-scans were evaluated 'blindly' by independent observers after pooling of the patient studies with 20 and 20 control studies, respectively. Only images strictly characteristic of AVM were classified as positive. The nosographic sensitivity of both methods was about 70%, in a few patients they were supplementary. Neither CT nor scintigraphy were able to detect lesions of less than 2 cm diameter. The methods seem to be of equal and rather high specificity, and are both well suited as screening procedures. CT provides additional information as to other intracranial abnormalities. The screening method of first choice when AVM is suspected may be CT or angioscintigraphy, depending on availability of equipment and expertise.

Better psychological functioning and higher social status may largely explain the apparent health benefits of wine: a study of wine and beer drinking in young Danish adults.

BACKGROUND: Findings from a recent series of Danish studies suggest that moderate wine drinkers are healthier than those who drink other alcoholic beverages or those who abstain. OBJECTIVE: To identify possible explanatory factors associated with the health benefits of wine consumption through the examination of a wide spectrum of social, cognitive, and personality characteristics related to both beverage choice and health in young Danish adults. SUBJECTS AND METHODS: Descriptive cross-sectional study of characteristics associated with beverage choice in a sample of 363 men and 330 women between the ages of 29 and 34 years, selected from the Copenhagen Perinatal Cohort on the basis of perinatal records. MAIN OUTCOME MEASURES: Socioeconomic status, education, IQ, personality, psychiatric symptoms, and health-related behaviors, including alcohol consumption, were analyzed. The outcome variables were subjected to linear and logistic regression analyses with 2 factors (beer and wine), each with 2 levels (drinking or not drinking a certain beverage type). RESULTS: Wine drinking was significantly associated with higher IQ, higher parental educational level, and higher socioeconomic status. Beer drinking was significantly associated with lower scores on the same variables. On scales concerning personality, psychiatric symptoms, and health-related behaviors, wine drinking was associated with optimal functioning and beer drinking with suboptimal functioning. CONCLUSIONS: Our data demonstrate that wine drinking is a general indicator of optimal social, cognitive, and personality development in Denmark. Similar social, cognitive, and personality factors have also been associated with better health in many populations. Consequently, the association between drinking habits and social and psychological characteristics, in large part, may explain the apparent health benefits of wine.
