Test-retest reliability of retrospective self-reports in three populations of alcohol abusers

The reliability of alcohol abusers' retrospective self-reports was evaluated using a time-line follow-back interview technique. Independent groups of male subjects were interviewed in three different treatment settings (outpatient,n=12; inpatient,n=12; residential,n=12) on two separate occasions to assess the test-retest reliability of their self-reports of daily drinking and related events occurring 1 year prior to treatment. Correlational and scatterplot analyses generally showed a high correlation and low discrepancy between the two sets of interview responses for all groups. However, since some population differences were found in the reliability of reports for some variables, further research is needed to delineate the conditions under which reliable and valid retrospective self-reports can be obtained from different populations of alcohol abusers.This research was supported, in part, by Grant No. AA07072 from the National Institute on Alcohol Abuse and Alcoholism to Vanderbilt University.     

BRIEF HIERARCHICAL ASSESSMENT OF POTENTIAL TREATMENT COMPONENTS WITH CHILDREN IN AN OUTPATIENT CLINIC

Seven parents conducted assessments in an outpatient clinic using a prescribed hierarchy of antecedent and consequence treatment components for their children's problem behavior. Brief assessment of potential treatment components was conducted to identify variables that controlled the children's appropriate behavior. Experimental control via a brief reversal was achieved for 6 of the 7 children, (1 child continued to behave appropriately following initial improvement in behavior). For these 6 children, improved behavior occurred with changes in treatment components. Our results extend previous studies of direct assessment procedures conducted in outpatient clinic settings.     

A study of the classification capabilities of neural networks using unsupervised learning: A comparison withK-means clustering

Several neural networks have been proposed in the general literature for pattern recognition and clustering, but little empirical comparison with traditional methods has been done. The results reported here compare neural networks using Kohonen learning with a traditional clustering method (K-means) in an experimental design using simulated data with known cluster solutions. Two types of neural networks were examined, both of which used unsupervised learning to perform the clustering. One used Kohonen learning with a conscience and the other used Kohonen learning without a conscience mechanism. The performance of these nets was examined with respect to changes in the number of attributes, the number of clusters, and the amount of error in the data. Generally, theK-means procedure had fewer points misclassified while the classification accuracy of neural networks worsened as the number of clusters in the data increased from two to five.Acknowledgements: Sara Dickson, Vidya Nair, and Beth Means assisted with the neural network analyses.     

Is medicine hermeneutics all the way down?

Several recent publications have suggested that hermeneutics, the method of literary criticism, might prove to be useful in medicine. In this essay I consider this thesis with particular attention to the claim that medicine is hermeneutics all the way down. After examining an anti-positivist critique of positivist medicine and arguing that hermeneutic interpretation involves a more radical critique of modern medicine, I examine the supposed consequences of hermeneutical universalism:relativism, skepticism andantirealism which further evaluation reveals to be only potential consequences of hermeneutics. A brief discussion ofphronesis and of the possible texts of medicine concludes the article.     

An examination of gender differences for job satisfaction,mental health,and occupational stress among senior U. K. civil servants

This study found that gender differences exist within senior U.K. civil servants. Females within the civil service were significantly more job dissatisfied, and suffered from poorer mental and physical ill health. They also showed more concern about their role at work, the factors associated with their particular job, the job's relationship to the home environment, and the constraints of the job. Males were more affected by how much control they felt they had at work, and by their hard-driving and achievement oriented behavior.     

A BRIEF COMPONENT ANALYSIS OF POTENTIAL TREATMENT PACKAGES IN AN OUTPATIENT CLINIC SETTING WITH YOUNG CHILDREN

The purpose of this study was to develop outpatient clinic assessments that allowed us to assess multiple treatment variables, produce relatively quick effects, and isolate active treatment components. Assessment began by evaluating a treatment package consisting of antecedent and consequence variables followed by a component analysis to determine the separate effects of the treatment variables. Three examples of the findings are presented.
