Prevalence and Diagnostic Correlates of DSM-IV Pathological Gambling in Psychiatric Outpatients

Studies of the prevalence of pathological gambling (PG) in psychiatric and substance abusing patients suggest that the disorder is not rare. Most studies have been of substance abusers in treatment, and the rate of PG has been found to be several times higher than the rate found in community based epidemiological surveys. However, only one study has examined the prevalence of PG in a heterogeneous sample of patients, and this was a study of psychiatric inpatients. We are not aware of any prior study of the prevalence of PG in a psychiatric outpatient sample. In the present report from the Rhode Island Methods to Improve Diagnosis and Services (MIDAS) project we examined the current and lifetime prevalence of PG in 1,709 psychiatric outpatients interviewed with a semi-structured diagnostic interview that included a module to diagnose DSM-IV PG. Forty (2.3%) patients had a lifetime history of DSM-IV PG, all of whom had at least one other DSM-IV axis I disorder. Patients with PG had significantly more axis I disorders than patients without PG, and had significantly higher rates of bipolar disorder, social phobia, panic disorder with agoraphobia, alcohol use disorder, and other impulse control disorders. Possible reasons for the low prevalence of PG in our sample are discussed.     

Functional foods for cardiovascular disease in women

Cardiovascular disease (CVD) is the leading cause of death in women. Functional food consumption can play an important role in the prevention and treatment of CVD. The purpose of this review is to establish recommendations for the intake of functional food ingredients in a healthy diet, such as soy proteins and isoflavone, omega-3 fatty acids (FAs) from fish oils (FOs) including eicosapentaenoic acid (EPA) and docoshexaenoic acid (DHA) and plant sterols-(PS) enriched foods - for prevention and treatment of CVD in postmenopausal women. First, controversial results exist on CVD risk factors after intake of soy protein and isoflavone that indicates that further clinical studies need to be done to better understand their role in maintaining and improving cholesterol levels. However, since soy contains polyunsaturated fats, replacing some higher fat meat protein sources with soy products may contribute to cardiovascular health. Secondly, FOs, including EPA and DHA, have shown promising effects for lowering triglyceride levels. In addition, emerging research appears to show that omega-3 FAs may have additional health effects with improved arterial health and a reduction in oxidative stress in postmenopausal women. Thirdly, foods and beverages supplemented with PS may reduce cholesterol; therefore, are a worthy addition to interventions aimed at lowering heart disease risk in women. Overall, incorporating functional foods into a healthy diet may be beneficial in helping to reduce lipids levels and thus the risk of CVD.     

Effects of human-related disturbance on breeding success of urban and non-urban blue tits (<Emphasis Type="Italic">Cyanistes caeruleus</Emphasis>)

There is a need to study the effects of urbanization on wildlife in order to understand the ecological implications of increasing urbanization and find out how to reduce its threats to biodiversity. The blue tit evolved as a forest species and prefers deciduous and mixed forests, whereas its nesting in urban habitats is a more recent phenomenon. Our long-term study of blue tit populations has been conducted in two habitats: an urban parkland (frequently visited by people) and a deciduous forest outside of the city. Using linear mixed modeling, we revealed that a relationship of blue tit breeding success (and the number of fledglings) with thermal conditions in May differed between the urban parkland and the forest. While the relationship was positive in the forest, it was negative in the parkland. In addition, breeding success in the parkland increased with increasing number of rainy days in May. We argue that the main possible reason for such patterns is human activity in the parkland, which interferes with tit parental care, especially the regular feeding of nestlings, whereas it is evidently associated with weather conditions. Human disturbance in the forest is likely to be negligible.     

On the efficiency of some non-orthogonal split-plot×split-block designs with control treatments

Many split-plot×split-block (SPSB) type experiments used in agriculture, biochemistry or plant protection are designed to study new crop plant cultivars or chemical agents. In these experiments it is usually very important to compare test treatments with the so-called control treatments. It happens yet that experimental material is limited and it does not allow using a complete (orthogonal) SPSB design. In the paper we propose a non-orthogonal SPSB design for consideration. Two cases of the design are presented here, i.e. when its incompleteness is connected with a crossed treatment structure only or with a nested treatment structure only. It is assumed the factors' levels connected with the incompleteness of the design are split into two groups: a set of test treatments and a set of control treatments. The method of constructions involves applying augmented block designs for some factors' levels. In a modelling data obtained from such experiments the structure of experimental material and appropriate randomization scheme of the different kinds of units before they enter the experiment are taken into account. With respect to the analysis of the obtained randomization model the approach typical to the multistratum experiments with orthogonal block structure is adapted. The proposed statistical analysis of linear model obtained includes estimation of parameters, testing general and particular hypotheses defined by the (basic) treatment contrasts with special reference to the notion of general balance.     

Unemployment in Poland - causes and remedial measures

This article describes unemployment and labor market policy in Poland after 1989. The analysis is based on official statistics, legislation and Polish social science literature. The unemployment situation in Poland is continually changing. Conclusions drawn by social scientists in 1991 and 1992 no longer give an adequate account of labor market trends in 1995. Steeply rising unemployment is the most traumatic upheaval in post-Communist Polish society. At the end of 1989, the number of people looking for work in Poland was far less than the number of available jobs. But by the end of 1992 there were 62 job-seekers for every job opening, dropping to 56 in September 1994. The social problems associated with unemployment vary from region to region. Women and young people predominate among the unemployed. The Polish government set up a Work Fund in January 1990 to alleviate unemployment. The Work Fund is the first real measure taken to assist the unemployed, but new legislation is needed if it is to become more effective.     

Reluctant Reforms: The Case of Kazakhstan

This paper investigates what happens during reluctant reforms in which normative imperatives conflict with self-interest. In the literature one of the expected outcomes is hypocrisy. However, the claim of hypocrisy is a strong one and needs backing. The purpose of this paper is to investigate on the basis of which indicators such claims can be warranted and whether these indicators are found in the case of reforms in the Republic of Kazakhstan. The common thread in the literature about hypocrisy is the point of inconsistency. Inconsistency in two ways: in the case of reforms to claim to induce huge changes, while resulting in nominal reforms, not changing anything; and inconsistency in the reactions to and opinions about such changes showing ‘differential judgments according to contexts’. This is investigated for the reforms in Kazakhstan with regard to promoting democracy and protecting human rights during the last decade. The analysis argues that these reforms as well as the international reactions do possess all the elements indicative for hypocrisy. At the end the implications for research on reforms are discussed.     

Individual control treatment in split-plot experiments

The paper deals with experiments laid out in a complete or an incomplete split-plot design in which one control (standard) treatment occurs in addition to the usual treatments. Usually the control (standard) treatment has been treated as one specific factor level. In this paper, in contrast to others in this area, the control (standard) may not be strictly connected with treatment combinations. The new incomplete split-plot designs with control satisfy all generally accepted methodological requirements, with special reference to the problems of randomisation. Moreover, tools are described which allow checking of the general balance or efficiency of the design, as well as performance of experiments with inference.

A Psychometric Evaluation of the DSM-IV Pathological Gambling Diagnostic Criteria

Specific diagnostic criteria for pathological gambling (PG) have been available for 25 years, since the publication of DSM-III. Little research has examined the psychometric performance of the diagnostic criteria. The goal of the present report from the Rhode Island Methods to Improve Diagnostic Assessment and Services (MIDAS) project was to examine the sensitivity, specificity and predictive values of the DSM-IV PG criteria for psychiatric outpatients who screened positive for a gambling problem. A total of 1709 psychiatric outpatients were evaluated with a semistructured diagnostic interview for PG. Of all patients 88 screened positive for PG, 40 of whom met DSM-IV diagnostic criteria for a lifetime history of PG. All ten DSM-IV criteria were significantly more frequent in the PG group. The sensitivity of the criteria ranged from 25.0% to 90.0% (mean = 67.8%), whereas specificity ranged from 62.5% to 100% (mean = 81.9%). Positive predictive values ranged from 64.1% to 100% (mean = 78.9%), and negative predictive values ranged from 61.5% to 90.7% (mean = 77.1%). Guidelines are recommended for determining whether a diagnostic criterion should be retained as part of the set of diagnostic criteria, and our results suggested that two of the DSM-IV PG criteria are candidates for elimination (criterion 8—commitment of illegal acts; criterion 10—reliance on others for financial assistance to relieve a desperate financial problem).
