Episodic autobiographical memory in depression: Specificity, autonoetic consciousness, and self-perspective

Autobiographical memory (AM) and the self are closely linked. AM retrieval in depression is characterized by a lack of specificity, suggesting an impairment of episodic AM. Autonoetic consciousness and self-perspective, which are critical to episodic AM, have never been addressed in depression. Twenty-one depressed inpatients and 21 matched controls were given an episodic AM task designed to assess positive and negative memories regarding specificity, autonoetic consciousness (remember/know procedure), and self-perspective (field/observer procedure). For specificity, "remember", and "field" responses, ANOVAs revealed a main group effect and a group x valence interaction. Between groups, patients showed lower scores than controls for positive memories. Within groups, patients showed greater scores for negative memories, and controls showed greater scores for positive memories. There is a global episodic AM impairment of positive memories in depression regarding specificity, autonoetic consciousness, and self-perspective. Our results suggest new cognitive interventions to improve the self-relevance of positive memories in depression.     

Intelligence and individual differences in becoming neurally efficient

Physiological approaches to human psychometric intelligence have shown a higher neural efficiency (i.e. less cortical activation) during cognitive performance in brighter subjects. The main aim of this study was to explore the relationship between intelligence and cortical activation patterns in the framework of the learning test concept. In 27 participants we assessed the topography and extent of cortical activation by means of event-related desynchronization (ERD) during reasoning tests in a pre-test--training--post-test design and related it to psychometric intelligence (measured by the German Leistungs-Prüf-System, LPS). Significant associations between intelligence and cortical activation patterns were exclusively found at anterior (frontal) recording sites, which corroborates the central role of the frontal lobe for higher-order cognitive functions. The hypothesized negative intelligence-activation correlation was observed only after the training, i.e. in the post-test, but not in the pre-test. More important, the decrease in cortical investment from pre-test to post-test correlated negatively with intelligence, indicating that the higher the subjects' general mental ability the larger the decrease in the amount of cortical activation. These findings suggest intelligence-related individual differences in becoming neurally efficient.     

Stressful work, psychological job strain, and turnover: a 2-year prospective cohort study of truck drivers

Based on a model that combines existing organizational stress theory and job transition theory, this 2-year longitudinal study examined antecedents and consequences of turnover among Dutch truck drivers. For this purpose, self-reported data on stressful work (job demands and control), psychological strain (need for recovery after work and fatigue), and turnover were obtained from 820 drivers in 1998 and 2000. In agreement with the model, the results showed that strain mediates the influence of stressful work on voluntary turnover. Also in conformity with the model, job movement to any job outside the trucking industry (i.e., interoccupational turnover) resulted in a larger strain reduction as compared to job movement within the trucking industry (intraoccupational turnover). Finally, strain was found to stimulate interoccupational turnover more strongly than it stimulated intraoccupational turnover. These findings provide a thorough validation of existing turnover theory and give new insights into the turnover (decision) process.     

The antecedents of aggressive behavior among men with schizophrenia: a prospective investigation of patients in community treatment

The association between psychotic symptoms and violence is unclear, due in part to methodological features of investigations that have examined this question, and in part to the fact that the association likely differs by disorder and treatment conditions. Using data from The Comparative Study of the Prevention of Crime and Violence by Mentally Ill Persons, we examined 128 men with schizophrenia or schizoaffective disorder discharged from general and forensic psychiatric hospitals in Canada, Finland, Germany, and Sweden. The association between symptoms and aggressive behavior was studied during two 6 month periods when the patients lived in the community. Severe positive and negative symptoms of psychosis, depression, and anxiety were measured at the beginning of each of the 6 month periods. In addition, at the beginning of the second 6 month period changes in symptoms in the previous period were indexed. Aggressive behavior was measured in each 6 month period by reports from patients and from collaterals. During the first 6 months post-discharge, after controlling for the presence of antisocial personality disorder or PCL score and past diagnoses of alcohol/drug abuse/dependence, the presence of a severe positive symptom significantly increased the risk of aggressive behavior. During the second 6 month period, after controlling for antisocial personality disorder or PCL score and self-reported alcohol/drug use, the presence of a severe positive symptom, a TCO symptom, and an increase in TCO symptoms significantly increased the risk of aggressive behavior. Neither depot medications nor obligatory community treatment reduced the risk of aggressive behavior after controlling for the presence of a severe positive symptom and/or TCO symptoms. These findings suggest that, among men with schizophrenia being treated in the community, the presence of severe psychotic symptoms and the development of TCO symptoms are antecedents of aggressive behavior.     

Comparability of self-report checklist and interview data in the assessment of stressful life events in young adults

The purpose of this study was to evaluate the incremental value of conducting an interview to assess stressful life events over the self-report questionnaire approach, first by examining the degree to which life events reported on a questionnaire met inclusion criteria in a detailed stress interview, and second, by comparing the magnitude of prospective associations with depression symptoms for the two different assessment procedures. Data from the Oregon Adolescent Depression Project were examined, in which 191 community-residing young adults (55% female; M age=23.6, SD=0.6) completed a mailed questionnaire assessing the frequency with which 33 life events had occurred to them or to other important people in their lives prior to the diagnostic and stress interviews. An average of 67.5% of events occurring to self met criteria for classification as a life event on the stress interview, as did 19.7% of the events occurring to others. Events having a large effect on the participant had a greater likelihood of meeting inclusion criteria on the stress interview. Contrary to expectation, stress scores from the interview assessment did not result in stronger associations with depression. Recommendations for assessment of stressful life events are offered.     

Comparison of social time-out and activity time-out procedures in suppressing ethanol self-administration in alcoholics

The experiments compared the potencies of three different contingent time-out procedures for suppressing drinking in alcoholics, and also compared two different experimental methodologies for conducting such studies. In a residential research ward setting fourteen volunteer chronic alcoholics were given daily access to 17 alcoholic drinks provided that a minimum of 40 min elapsed between receiving successive drinks. Each drink contained 1 oz 95-proof ethanol in orange juice. During the baseline condition subjects were free to drink with no behavioral restrictions. However during the time-out conditions, specific behavioral restrictions were imposed on the subjects for the 40-min period following receipt of each drink. The results showed that Social time-out suppressed drinking to 71 per cent of baseline conditions, while Activity time-out and the combined Social and Activity time-out suppressed intake to 36 and 24 per cent, respectively. The study also demonstrated that similar experimental results were obtained when subjects were continuously exposed to the experimental conditions for a number of consecutive days. or intermittently exposed to different conditions in a mixed order over successive days.     

Goal attainment scaling: An idiosyncratic method to assess treatment effectiveness in agoraphobia

Goal attainment scaling (GAS) is an individually tailored way to measure treatment gains, using a highly standardized procedure. An advantage of the method is that it takes into account individual characteristics of the patients, and at the same time the data are suitable for quantitative analysis and comparable across patients. Despite the wide acceptance and use of the method in the evaluation of psychotherapy, data on its psychometric properties are rather scarce. In the current study, GAS was used as one of several outcome measures in a research project on the effectiveness of various treatments for panic disorder with agoraphobia. Guidelines for GAS are presented as well as data on the reliability and validity of the procedure. Results indicate that the procedure is reliable, valid, and sensitive to the improvement of patients during treatment. Comparison of GAS with standardized measures revealed considerable concordance, although the clinical end status of patients diverged somewhat dependent on the measure considered.     

On the Relation Between Religiosity and the Endorsement of Conspiracy Theories: The Role of Political Orientation

Religious and conspiracy beliefs share the feature of assuming powerful forces that determine the fate of the world. Correspondingly, they have been theorized to address similar psychological needs and to be based on similar cognitions, but there exist little authoritative answers about their relationship. We delineate two theory-driven possibilities. If conspiracy theories and religions serve as surrogates for each other by fulfilling similar needs, the two beliefs should be negatively correlated. If conspiracy and religious beliefs stem from the same values and cognitions, this would speak for a positive correlation that might be diminished—for example—by controlling for shared political ideologies. We approached the question with a meta-analysis (N = 10,242), partial correlations from large Christian-dominated datasets from Germany, Poland, and the United States (N = 12,612), and a preregistered U.S. study (N = 500). The results indicate that the correlations between religiosity and conspiracy theory endorsement were positive, and political orientation shared large parts of this covariance. Correlations of religiosity with the more need-related conspiracy mentality differed between countries. We conclude that similarities in the explanatory style and ideologies seem to be central for the relation between intrinsic religiosity and endorsing conspiracy theories, but psychological needs only play a minor role.
