Valuing Environmental Outcomes: Preferences for Constant or Improving Sequences

Experimental results on individuals' preferences for temporal sequences of environmental outcomes related to air quality and near-shore ocean water quality are compared with preferences for sequences of health and monetary outcomes. Generally, graduate business student participants gave significantly lower ratings to environmental and health sequences (with equal means) that worsened over time, relative to the ratings they gave to sequences that either remained the same or improved over time. This pattern was reversed by the participants when they faced sequences of monetary payments. This preference structure held for both short (5-year) and long (50-year) time horizons, and it was confirmed with choice data. A model proposed by Loewenstein and Prelec for the valuation of sequences of outcomes was applied to the current data set and compared to the traditional discounting model. In all cases, the model that incorporated “Gestalt” features of the sequence (slope and uniformity) performed better than the net present value discounting model at predicting the mean ratings for the sequences in the different domains.     

Use of Self-Report Measures of Anxiety and Depression in Outpatients with Schizophrenia: Reliability and Validity

The psychometrics of many self-report measures of anxiety and depression have been established for patients with anxiety disorders, but little is known about use of these measures in patients with psychotic disorders. This study examined psychometrics of commonly used self-report measures. Self-report measures and interviewer ratings were collected on 33 outpatients diagnosed with schizophrenia disorders. A sample of 46 patients with anxiety disorders completed the same self-report measures. Internal consistency was high for the self-report measures in both samples. Test-retest reliability was moderate to high. Scores on self-report measures were correlated with interviewer ratings and with scores on other self-report measures of similar constructs, supporting the convergent validity of the measures. Reliable and valid information about anxiety and depression can be obtained through administering the self-report measures to outpatients diagnosed with psychotic disorders. There was more overlap among measures than was expected, possibly because of poor discriminant validity. One explanation of this may be that anxiety constructs overlap more in patients with schizophrenia or related disorders than in non-psychotic populations.     

Confirming the Factor Structure of Attention Deficit Hyperactivity Disorder Symptoms in Adult, Nonclinical Samples

Three separate models have been proposed to describe the factor structure of attention deficit hyperactivity disorder (ADHD) in the past 20 years. The Diagnostic and Statistical Manual of Mental Disorders-III (DSM-III, 1980) proposed 3 separate factors of inattention, hyperactivity, and impulsivity. The DSM-III-R (1987) proposed a single factor. The DSM-IV (1994) described the disorder as having 2 factors: hyperactivity/impulsivity and inattention. The following 2 studies employed confirmatory factor analysis to compare each of these models and 3 alternative models. University students completed questionnaires that assessed each of the 18 symptoms listed in the DSM-IV for ADHD. The 3-factor model fit the data significantly better than each of the other models in both studies. These findings suggest that a 3-factor model of inattention, hyperactivity, and impulsivity describes adult ADHD symptoms better than current alternatives.     

Psychodynamik und neurophysiologischer Befund bei einem Patienten mit einer zwanghaften Lesestörung

The present single case study is aimed to investigate neuro-physiological correlates of checking and ordering compulsions in a 40 years old patient suffering from obsessive-compulsive disorder (OCD) by means of the functional magnetic resonance imaging (fMRI) method. After the presentation of the psychogenesis and psychodynamic of the OCD case, the cardinal symptom, a compulsive reading disturbance, is described in detail. Based on the symptom analysis eight different texts, hierarchically arranged by their degrees of difficulty were composed and presented to the patient for reading during fMRI. The results of the fMRI during symptom provocation display significant increase of activation in fronto-thalamic-cortical neural circuits with the occurence of compulsive reading disturbances compared with unproblematic texts and with the reading of a control subject. The findings are discussed in relation to the neurobiologic literature as well as to an object-psychological model of the OCD.     

A naturalistic longitudinal evaluation of counselling in primary care

This study evaluated the effectiveness of generic counselling in a primary healthcare setting during three months of counselling and followed up the patients' progress after counselling had finished for the next twenty-one months. Questionnaires were completed by patients within the Dorset Primary Care counselling service on referral to counselling and at set points afterwards. A naturally occurring waiting-list group was compared with patients receiving counselling at baseline and three months. Measurements were taken of patients' psychiatric symptomatology, quality of life (QOL) and self-esteem. Patients who received counselling made highly significant improvements compared with those on the waiting list. These improvements were maintained throughout the long-term follow-up. This would indicate that generic counselling has positive effects that can be maintained for a long period of time after counselling has been completed.     

Encoding and output order processes in short-term order recall of distinctive items.

Adults recalled the order of the letters in one of two four-letter segments following a distractor task. They knew in advance the identity of the letters in each segment. A letter was made distinctive by replacing it with a red dash. This unusual form of distinctiveness generally had negative effects on recall of both the segment containing the missing letter and the absent letter within the segment. Encoding and output processes were manipulated by varying precue information and recall order instructions, respectively. Informing participants in advance whether or not a trial would contain a distinctive (i.e., missing) letter depressed recall. Constraining output order eliminated the disadvantage for the absent letter. The results are discussed in terms of encoding and output order processes in short-term recall of order information.     

Overcoming Barriers to Collaboration Between Basic Behavioral Scientists and Public Health Scientists in Research on Mental Disorders

The behavioral and public health sciences both have a long and rich history supporting basic, translational, and applied research aimed at improving human lives and reducing human suffering. Through the complementary expertise of these disciplines, investigators have contributed to significant, worldwide improvements in mental and physical health. Further gains can be achieved through collaborative research among scientists in these 2 fields. Unfortunately, there are a number of barriers to such collaboration originating in different intellectual traditions, research methods, and the structure and values of academia. We identify these barriers and potential strategies for overcoming them. Several areas for future collaborative research appear promising, especially comorbid mental and physical disorders, adherence to interventions, stigma, and emotional processes. Theory-guided preventive interventions may represent especially fertile areas of collaborative effort.     

Crones, Dirty Old Men, Sexy Seniors: Representations of the Sexuality of Older Persons

The representations of the sexuality of older persons in American society are neither flattering nor accurate. Often what is presented is filled with confusion, uncertainty, and contradictions. Sexuality of old people, like sexuality of adolescents, frightens most adults in between. Evidence suggests hope that in popular culture, conventional representations of sexless older people are finally undergoing a change. The popular literature aimed at elderly or midlife audiences increasingly portrays older persons as healthy, vigorous, and not unattractive. Since in the popular mind attractiveness and sexuality are believed to be closely linked, this change signals an increased willingness to credit old people who are aging well (i.e., who look and act young) with being sexually interested and probably active.     

On-line Homework/Quiz/Exam applet: Freely available Java software for evaluating performance on line

The Homework/Quiz/Exam applet is a freely available Java program that can be used to evaluate student performance on line for any content authored by a teacher. It has database connectivity so that student scores are automatically recorded. It allows several different types of questions. Each question can be linked to images and detailed story problems. Three levels of feedback are provided to student responses. It allows teachers to randomize the sequence of questions and to randomize which of several options is the correct answer in multiple-choice questions. The creation and editing of questions involves menu selections, buttonpresses, and the typing of content; no programming knowledge is required. The code is open source in order to encourage modifications that will meet individual pedagogical needs.
